Starting from technological innovations in the form of (1) physical adaptation studies on benefits and use of walking, (2) BUM Desa's fortune research in terms of economic functions and social functions that are efficient, (3) female role seekers seeking additional income from the informal sector, ( 4) study of coffee pulp extraction for oil products and various organic acids, (5) education studies to improve students' mathematical analytical skills with Bridge Analogy method, (6) study of adding magnesium and iron to micro algae cultures to increase population and lipid production , (7) descriptive study on Public-Private Cooperation to determine the most effective between Built-Transfer, Built-Operate-Transfer or Built-Transfer-Operate on Bandar Radin Inten II, and (8) friendly geopolymer research even when mixed with NaOH the more so that the quality of absorption, porosity and specific gravity can replace conventional cement.

    For more details, Editorial presents prawacana that has been compiled as follows:

    Akhmad Baiquni Muhaemin conducted a study which should be used to measure the walking ability of the local people of Bandar Lampung in Kemiling compared to data from the literature. From the sample data obtained, Muhaemin concluded that the local Kemiling community, Bandar Lampung, assumed that walking was only an activity that was not too influenced by the purpose and quality in the trip.

    Ridwan Saifuddin conducted research on the benefits of BUM Desa as expected by the Government. For his research sample, Saifuddin took one BUM Desa, BUM Desa Swadesa Arta Mandiri, Desa Wonomarto, Kabupaten Lampung Utara, which was not yet clear the fiscal magnitude of its business. BUM Desa Swadesa Arta Mandiri has several business units, such as managing water tourism, trade, village markets, waste management, and financial institutions. It is expected that BUM Desa Swadesa Arta Mandiri is able to synergize economic functions and financial functions so that it is profitable. Without analysis of management personnel (board of directors) and personnel curators (board of commissioners), Saifuddin concluded that BUM Desa Swadesa Arta Mandiri had not been financially profitable or had a social role.

    Susianti conducts research on empowering women in the informal sector in an effort to increase income. With a directed sampling method for families in Sleman Regency, DIY, Susianti tries to analyze the business reasons for women to work in the informal sector. In fact, Sleman Regency, DIY is a district that is not yet prosperous, surely Susianti's conclusion is the main reason and motivation that encourages women to work in the informal sector in Sleman Regency to increase family income to meet their needs.

    Muhammad Hanif and Heru argued that the remaining coffee pulp from the instant coffee industry could still be used to extract the coffee oil. Heru and Hanif conducted a study by extracting coffee oil from Robusta coffee pulp using Soxhlet extractor, by varying the time and mass of instant coffee pulp. The results showed that the percentage of extracts did not differ significantly for extraction times for 6, 7 and 8 hours. Coffee pulp mass variation was carried out for extraction time 6 and 8 hours and it was observed that the mass variation of coffee pulp (15, 20, and 25 g) was generally significant for the extracts obtained, but not significant for coffee pulp mass 15 g with extraction time 6 and 8 hours.

    Nia Agustina, Nanang Supriadi, Komarudin argues that improving teaching and learning skills can be improved by Bridge Analogy. Understanding of students takes place independently through mathematical reasoning. The study was conducted on a sample population of class VIII students of SMP 19. In addition, the results of the study also obtained a difference in the increase in students' mathematical reasoning abilities in terms of self-efficacy.

    Anggi Pratiwi argues that the Tetraselmiss chuii micro algae which are fed with MgSO4.7H2O and FeSO4.7H2O as a source of magnesium and iron to increase lipid content. Algae were maintained in the reactor with a composition of 300 ml micro algae: 700 ml sea water with 30 ppt salinity and 2000 lux light. The results showed that the highest lipid content of 20,175% in Tetraselmis chuii microalgae was obtained by adding 6 grams of MgSO4.7H2O and on adding 36 µM FeSO4.7H2O.

    Dian Sera Fauzela, Bambang Utoyo Sutiyoso, Sasana Putra responded to the limited costs of providing infrastructure. Fauzela, Sutiyoso and Putra then examined the ability of Public Private Partnership (KPS) in the development of Radin Inten II Airport, South Lampung. Descriptive studies are carried out using the AHP (Analitycal Hierarchy Process) analysis technique which is used to analyze the best priority sequence that can be applied in the Public Private Partnership. AHP analysis directs the results to the form of Built-Transfer (BT) development rather than Built-Operate-Transfer (BOT) and Built-Transfer-Operate (BTO) because of doubts about the Government's side to be able to operate Intan II Radin Airport which is financially and management-wise satisfy customers.

    Muhammad Amin, David Candra B, Kusno Isnugroho, Yusuf Hendronursito, Reni Septiana argued that cheap geopolymers could be generated as expensive conventional cement substitutes. The materials for making geopolymers are pearlite, basalt and feldspart which are given the addition of NaOH to increase the absorption and porosity values. In their research, Amin et al. concluded that the more addition of NaOH the smaller the absorption and porosity and the greater the specific gravity of geopolymers so that it increases the strength of geopolymers. Amin et al. believes that the use of geopolymers as a substitute for cement will be environmentally friendly because it is an earth mineral, although the use of NaOH as a strong base has been very limited in industrial and household use.

    This Journal of Innovation and Development Volume 06 Number 03 contains eight scientific works from various studies. Starting from the work of technological innovations about the government innovation of public service delivery, evaluation of Lampung Province's Tuha Integrated Superior Vocational High School, disparity and structural transformation between regencies / cities in Kalimantan, character recognition of Lampung characters, hydroponic floating raft system on lettuce plants, portable measuring devices to measure retail gasoline, increase student understanding of Islamic value-based trigonometric concepts, and develop mathematical modules for the PQ4R model as sequentially below.

    Lesmana Rian Andhika conducts research on "Elements and Factors of Government Government Innovation in Public Service" and states that many innovations have been produced in the Government's public services but cannot show greater inclusiveness of benefits. Research conducted to evaluate the benefits of these innovations uses descriptive qualitative methods with deductively collected data from several scientific sources and Government regulations. The results of the study indicate that innovation governance contributes to improving the quality of public services, but innovation governance can also be evaluated from three sectors, namely: institutions as implementers, policy actors as decision makers, and community participation as recipients of Government service innovations.

    Ridwan Saifuddin, Elip Heldan, Zainal Mutaqim, Ika Tri Wulan who conducted the "Evaluation of the Tuha Child Integrated Integrated Vocational High School in Lampung Province" and argued that the establishment of the State Vocational School was a manifestation of the commitment to education development in the region. Thus an evaluation is needed to find out the existing conditions, the learning process, and the achievement of the educational process in the school with a descriptive-qualitative method. The evaluation results show that three main factors need to be strengthened, namely: Human Resources and Educational Administration, Management of Educational Quality through the Internal and External Quality Assurance System, Financial Management, Laboratory Facilities and Infrastructure, and Land Ownership status.

    Maria Christina Yuli Pratiwi who examined "Inter-Regency / City Structural Disparities & Transformations in Kalimantan" argued that the development between regions on the island of Borneo was uneven. The study was conducted to prove the effectiveness of the Kutnez hypothesis on the island of Borneo. The study utilized the Klassen typology, Williamson index, Theil entropy index, Structural Transformation, and Gini Ratio to analyze development inequality in 56 districts / cities during the period 2010-2016. The results showed that: (1) the majority of the area on Kalimantan island is classified as developing fast, (2) the Kutnetz hypothesis applies on the island of Borneo, (3) development inequality on the island of Borneo tends to decrease, (4) the East Kalimantan Province the biggest cause of development inequality on the island of Borneo, and (5) the highest structural transformation occurs in Kutai Kartanegara Regency.

    Halim Abdillah Sholeh, Yessi Mulyani, Hery Dian Septama conducted a study on "Comparative Study of the Characteristics of Lampung Character Recognition with the Edge Detection Method of Roberts and Sobel" because they were concerned about the extinction of the Lampung script culture because it was rarely used. The study was conducted to preserve the Lampung script culture through the introduction of digital Lampung scripts with image processing and pattern recognition methods. The research was conducted in two stages, namely the Training Stage using image processing and the Training Stage with the back propagation method training in Artificial Neural Networks (ANN). In Edge Detection image processing, characters from Lampung characters were analyzed by line letter pattern using edge detection Robert and Sobel. Image processing results are continued with ANN analysis. The results showed that the Sobel edge detection method was better than Roberts with error percentage of 14.5 and 28.5% respectively.

    Carmia Dwi Pratiwi, Ary Susatyo Nugroho, M. Anas Dzakiy conducted a study of "Response to Growth and Production of Three Lettuce Varieties in the Hydroponic Floating Raft System" of three lettuce varieties namely Junction (Lactuca sativa capitata), Romaine (Ls longfolia), and Red Salad Bowl (Ls crispa) with floating raft hydroponic technique. The study was conducted using a completely randomized design with three replications and a simple random sample was taken. The study compared plant variables: plant height, number of leaves and wet weight; and laying plants: near nutrient reservoirs, in the middle, and near residual reservoirs. The results showed that the best plant response to growth and production was lettuce placed near nutrient reservoirs.

    Wahyu Saputra, Fransiskus Simanjuntak, Prasetyo Budiyanto, Andri Sepriyawan developed the "DBE Meter for Retail Gasoline Meters" because they thought that the Public Fuel Filling Stations (SPBUs) were unable to service motorized vehicles whose development was so rapid. As an alternative, consumers turn to retail fuel sellers who doubt the accuracy of their measuring devices. This study designed-built an electronic measuring device in the form of a flow meter that uses an arduino uno controller, a simple portable measuring funnel that has been programmed as a measuring device to control. The flow of fuel that goes into the vehicle's fuel tank is put into the measuring funnel so that it can display the amount of fuel being supplied. The test results showed that the measurement error was 0.9 - 2.8% which was still at the permit limit.

    Nova Nindarti, Suherman, Syaiful Anwar who conducted the research "Improving the Concept of Trigonometry Based on Islamic Values ​​through Pocket Books" argues that trigonometry is a mathematical material about angles. The use of trigonometry in everyday life is seen in buildings. This study aims to improve the understanding of trigonometry concepts in students with the help of Islamic value-based pocket books in Liwa 2 Public High School, West Lampung Regency. The method used is Quasi Research Design with non-similar control groups. Sampling is done in cluster. The sequence of research starts from the initial exam, trigonometry concepts based on Islamic value books, and final examinations to assess the increase in mastery of students' trigonometry.

    Novicha Muthia, Netriwati, Iip Sugiharta conducted a research "Development of Mathematical Modules to Implement the PQ4R Model" which aims to develop a mathematics learning media in the form of a module assisted by the PQ4R model. For the development of learning media, the ADDIE procedure (Analyze, Design, Development, Implementation, Evaluation) is used through interviews, questionnaires, documentation and examinations. Data analysis techniques used are feasibility test, attractiveness test, and t test. The main results of this research and development are the mathematics learning modules for the PQ4R model which have been declared appropriate to be used as learning media with material scores 3.42 and media scores 3.77. The attractiveness test on a small scale obtained a score of 3.49 and on a large scale a score of 3.71 was obtained to obtain very interesting criteria. The effectiveness of media use tested t states that H1 is accepted which means that the module learning PQ4R model is effective for improving mathematics learning outcomes.

    The Journal of Innovation and Development Volume 06 Number 02 contains eight scientific papers from the study with different themes. Starting from the research on the production of sweet potatoes, cement and cellulose composite concrete, a strategic plan to safeguard cassava production as a staple food for Siger Rice, the use of biogas production waste from livestock waste as a source of soil health organic fertilizer, natural resource management that is not in accordance with good prerequisites governance , optimization of hydrolysis process on bioethanol fermentation of sorghum seeds of local and sweet varieties, software for translating Lampung-Indonesian sentences with attention -based neural machine translation approaches . A brief introduction to understanding each study topic is presented in the following summary:     


    Hasan Basri investigated the effect of five sweet potato varieties on sweet potato production if planted in the BPP Lampung field which did not explain its classification and fertility. The five sweet potato varieties grown were Sukuh Ayamurasaki, Sawentar, Cangkuang, and Antin-1. Basri's research used a randomized block design with three replications and a mean analysis using the smallest significant difference of 5%. The results obtained were respectively the highest and the lowest were Ayammurasaki, Sawentar, Sukuh, Antin-1, and Cangkuang varieties with consecutive production equivalent to 20.24;18.46; 17.20; 12.02; and 8.00 tons per ha . Basri has not yet concluded how well the production of each variety as stated in the description set by the Ministry of Agriculture.


    Annisa Mufida, M. Rouf Suprayogi, Edwin Azwar conducted a study on cellulose composite concrete fiber gedebok banana to obtain lighter material with strength and quality that matched even more than existing materials. Banana gedebok is ligned using NaOH to produce cellulose in powder and woven form and mixed with 0 and 5% into K-275 quality concrete mix. Analysis of banana gedebog which has been decomposed-lignin has cellulose content of 13.04%, hemicellulose 18.28% and lignin 0.67%. It turns out that concrete composites that have lower tensile strength and compressive strength compared to normal concrete, but the highest attenuation power of cellulose webbing concrete compared to cellulose powder concrete and normal concrete with absorbed sound intensity of 52-68 dB. From these conclusions, Mufida, Suprayogi and Azwar have not determined what their composite concrete benefits are.


    Henita Astuti, Alvi Yani, Suraya Kaffi conducted an assessment of the strategic plan for developing staple food based on local resources in Lampung Province. Astuti Yani and Kaffi argue that staple foods in Lampung Province are tapioca products in the form of Siger Rice. So many problems presented by these three researchers include handling cassava at abundant harvest, types of cassava that can be processed into Siger Rice, quality of Siger Rice food products, procedures for production processes, supporting human resource education, availability of adequate production houses, support resources, regulatory support, organized waste, registered P-IRT licenses, and program implementation are right on target, but effective solutions have not been described. Nevertheless Astuti, Yani and Kaffi argued that the results of their studies could be used to determine the Local Government's policy on cassava and Siger rice.


    Bambang Singgih, Susmiati repeated the survey that has been done a lot about the use of biogas production waste from livestock waste as a source of organic fertilizer. Singgih and Susmiati reiterated the importance of organic fertilizers as soil health materials. The results of their survey showed that livestock biogas waste contained organic, inorganic, NPK in various percent, and other nutrients, namelyamino acids, fatty acids, humic acid, vitamin B- 12, auxin hormones, cytokines, antibiotics, and micronutrients such as iron, copper, zinc, manganese, and molybdenum are not mentioned how much the concentration of% or ppm respectively. Aside from being an organic fertilizer, Singgih and Susmiati also mentioned the greatness of the biogas production waste for other uses such as bio-pesticides, biological fertilizers, regulating plant growth, animal feed, improving soil structure, increasing weed growth, increasing soil fertility and increasing soil microorganism activity even though not yet explained in detail from the results of their survey.


    Taufik Hidayat by praising the greatness of God for the abundance of the country that "has all" analyzing natural resource management in the perspective of good governance using descriptive-exploratory methods by utilizing available documents. Hidayat concluded that there were "mismanagement" in the pen g elolaan natural resources because management is not referring to the principles of good governance: participation, provision of law, transparency, responsiveness, orientation of the agreement, the balance, the effectiveness and kemangkusan, keterbuktian, and strategic vision.


    Banon Rustiaty conducted a study to calculate the optimization of the hydrolysis process on bioethanol fermentation of sorghum seeds of local Hermada varieties and Numbu sweet varieties. Research Rustiaty grain sorghum preceded by soaking in NaOH solution of 0.05% at a temperature of 45 ° C for 1.5 hours compared to without soaking. The results of his research showed that there was no difference in the ratio of fermentation between sorghum seeds which were soaked or not. The fermentation ratios obtained at NaOH immersion were 86.75 and 89.67%, while without immersion were 85.81 and 87.68% respectively for Hermada and Lumbu varieties. But in this study Rustiaty has not determined whether soaking sorghum seeds into NaOH solution is important as the initial treatment before fermentation is carried out.


    Muhtarom, Nurhadi Kusuma, Eri Purwanti conducted descriptive quantitative analysis to find out the Village Index Building in Gadingrejo District, Pringsewu Regency, Lampung Province. Their analysis used a data triangulation method which concluded that the majority of villages in Gadingrejo Subdistrict were included in the Developing Village Classification of 87%. The Social Resilience Index is the highest indicator in the realization of rural development in Gadingrejo sub-district, which is 0.71 which indicates that the average social / social development of the village in Gadingrejo sub-district is in Advanced Classification. In his discussion, Muhtarom Kusuma, and Purwanti did not discuss why there was a gap between the method of triangulation and the conclusions of the Developing Village Classification and Social Resilience Index which were in Advanced Classification.


    Zaenal Abidin, Adi Sucipto, Arief Budiman created a software for translating Lampung-Indonesian sentences with an attention -based neural machine translation (NMT) approach that blends encoder anddecoder inside the translation machine . Based on the test results, they concluded that the NMT approach used 25 single sentences without out-of-vocabulary (OOV), 25 single sentences with OOV, 25 compound sentences without OOV and 25 compound sentences with OOV showing understudy (BLEU) bilingual evaluation values obtained by approach NMT is 51.96%. In this study, Abidin, Sucipto, and Budiman have not mentioned how many single sentences and compound sentences both with and without OOV that meet the requirements of testing with the NMT approach.

    Journal of Innovation and Development Volume 0 6 No. 0 1 contains eight scientific papers with different themes. Starting from the modeling management of mineral resources based on community empowerment, efforts to increase students' learning activities, analysis of genetic differences in fish beronang and cobia berorigin Indonesia and Taiwan, utilization of animal waste into biogas in the biogas reactor dome type fixed (fixed dome), surveys of fishing activities in West Coast Pesisir Lampung, an analysis of the performance of the Development Planning Council (Musrenbang) of Lampung Province in 2017,   the use of mineral perlite mortar Lampung as aggregate material against strong to early press, and efforts to increase kedel ai in acid soil Mera h-Yellow Podzolic Lampung using Bokashi organic materials. A brief introduction to understanding each of the study topics is presented in the following sections:                         

    Taufik Hidayat and Yoka Pramadi establishes a community-based strengthening resource management model with financial inclusion in the form of training, provision of appropriate technology, assistance, post-management and financing.

    Ganjar Winata conducts tests to improve student learning activities using visual aids on mathematics subjects. The visual aids used are a combination of letter cards and number cards. Testing of combined card methods shows that material understanding is faster because students are encouraged to immediately master the material.

    Yudha Trinoegraha Adiputra, Jin Chywan Gwo and Te Hua Hsu compare genetic diversity fish beronang ( Siganus ) and cobia ( Ranchycentron canadum ) from Indonesia and Taiwan used DNA fingerprint method with AFLP ( amplified fragment length polymorphism ). The results show that Taiwan beronang different from beronang Indonesia with a distant genetic distance. In contrast, most Indonesian cobia join in a separate group of Taiwanese cobia populations into two groups. Thus the beronang population of Indonesia is genetically eligible to be developed as a cultivation commodity. The development of the Indonesian cobia population as a cultivation population can utilize the genetic source of the cobia of Taiwan to cope with inbreeding.

    Bambang Singgih and Yusmiati examine the use of livestock waste to be processed into biogas by anaerobic fermentation process is a series of biogas reactor equipment. Of the three types of biogas reactors were used that type of float, ti pe fixed dome, and the type of balloon, dome type fixed (fixed dome) recommended its use because of the cost of construction and maintenance is cheaper, can be made by farmers, and more durable than reactor balloon.

    Yudha Adiputra , Siti Hudaidah, Margie Brite, Andhika Bayu Saputra, Dede Nur Abdul Halim , and Firmansyah conducted a survey to fishermen and lob stamp collectors in West Coast District, Lampung from August to December 2016 . Survey results indicate that lobster catching activities did not develop, but there was a decrease in fishing volume . A high valuable lobster enis diminishing andtheir size is getting smaller. They conclude their p erlu the development of lobster fishery which is not only in the form of capture fisheries which are restricted to its capture quota, but also aquaculture fishery. In addition it is necessary to release lobster fries breeding results to anticipate increased consumption and protection of natural stocks .

    Ridwan Saifuddin, Dedy Hermawan, and Sigit Prasetyo analyzed the performance of Musrenbang Development Planning (Musrenbang) Lampung Province. The Musrenbang study is contained in the Government Work Plan (RKP) and Regional Government Work Plan (RKPD) of Lampung Province 2017 , and in the national medium-term planning document (RPJMN) and Lampung Province (RPJMD) 2015-2019. From the identification of 88 indicators of regional development goals , there are 79 indicators that have been realized in Lampung Province. It is concluded that the suitability level of the programis 88.76%, which according to the Performance Ministry Rating Scale of the Ministry of the Interior is included in the high category range.

    Via Apri Setiani, Syafriadi, Bramantyo Bayu Aji, and Muhammad Amin conduct research on the use of mineral perlite mortar Lampung as aggregate material against strong to early press. The peritans used are mesh 40 with cement composition : the pearlite is 1: 2, 1: 3, 1: 4 and 1: 5 . P erlit Lampung meet the standards as mortar aggregate material because it has a high Si content, namely 57.06 %. The results showed that the best press was obtained on mortar with cement composition: perlite 1: 2 ie 156.8 kg / cm 2 . The compressive strength of the mortar decreases with the increase in the number of pearlite in the cement composition : the pearlite of the SiO 2 bond with the free CaO which forms Ca (OH) 2, resulting in reduced mortar density and the formation of air cavities .

    Hasan Basri attempted to increase Lampung's keel ai on the less fertile Podsolik Mera h-Kuning acid by using bokashi organic material. Application of 15 ton / ha bokashi yielded yield of seeds / plants and per heavier plot compared with treatments without bokashi and bokashi 10 ton / ha ie 13.17 g / plant weight and 16,64 kg / plot equivalent to 1.69 ton / ha . Thus there is an opportunity to increase soybean production by administering high-dose bokashi 15 tons / ha.
