The objective of this experiment was to investigate the pattern of Violin Crab distribution at mangrove forest in Kahyapu and Gulf of Muaro. The methodology used in this experiment, carried out from 2017 to 2018, was a survey done by random sampling. The samples were taken from 2 stations at 10 plots, whose size was1m x 1m each. The variable measured included the crab pattern of distribution and abiotic factor which might affect the growth of the crabs, such as water pH, temperature, and salinity Muaro Labu Nawi.

The violin crab inhabitating Kahyapu showed random pattern of distribution while those in the Gulf of Muaro Labu Nawi had clustered and random distribution. Moreover, Kahyapu habitat had water temperature of 27–30 C, solution pH of 6.4–6.7, and salinity level of 26–28%.

The research was conducted at the Experimental Garden and Laboratory of the Payakumbuh State Agricultural Polytechnic. The treatments of biofertilizer were carried out by immersing the seeds in biofertilizer 4% solution for 12 hours, then maize plants were treated with a biofertilizer in the planting hole, and the age of the plants was 14, 28, 42, 56 days after planting. Observation parameters were carried out on endophytic bacteria of the maize plant and the number of bacterial populations.

For the sake of achieving self-sufficiency in soybeans, one important factor is the availability of scatter seeds. Provision of appropriate soybean seeds has a strategic role as a means of supporting increased soybean production. In the field, the seed flow system in Mojokerto Regency, East Java Province, is still facing problems, namely the absence of seed channels for rainy season cultivation in dry land so that it cannot grow a sustainable \"Jabalsim\" system. For this reason, this activity aims to 1) produce superior soybean seeds according to farmers' preferences to meet market demand, 2) grow seed producers in soybean development areas to ensure adequate supply and distribution of quality seeds of superior varieties, and 3) as well as assist in the application of technological innovations to reduce the yield gap. The results showed that the activity of seed production in Wuwut Village, Mojoanyar Sub-District, Mojokerto District could be categorized as independent. Indicators of independence are: 1) Establishment of a seed producer on behalf of Arifin with a certificate of breeder as Extention Seed producer number 030 / UPT.PSBTPH / MJK / VII / 2019, 2) Superior Varieties of Soybean has been adopted and developed (Dega I, Devon I, Deja II) at the research location even outside the research area, 3) Availability of seeds at all times for the needs of members, and 4) the emergence of a soybean seedling business that has partnered with seed providers. To maintain the continuity of the seeds producer that have been formed, monitoring of their business developments on a regular basis was needed. In addition, in the future, it is necessary to provide access to seed programs that are assisted as one of the seed providers and provide physical infrastructure support so that the speed and volume of seed production can increase.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84658568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
