This research reveals local farmers' cultivation practices using production inputs. The methods used are observation and interviews. Respondents were determined by deliberate methods. Research variables included sustainable agriculture indicators such as land conservation, agroforestry, integrated pest control, protective crops, crop nutrient management, and crop diversification. Data were obtained through a closed questionnaire with \"Yes\" or \"No\" questions. The answer \"Yes\" was given a score of 1, while the answer \"No\" was a score of 0. Next, the data is tabulated and analyzed using descriptive analysis. The results showed that farmers on Hiri Island maintain agricultural productivity by implementing sustainable agricultural practices with several indicators such as water source management 42%, integrated pest control 50%, crop diversification 65%, crop nutrition management 65%, land conservation 75%, and agroforestry 83%. Farmers on this island have implemented the concept of sustainable agriculture, but it needs to be done continuously by maximizing cultivation practices on small islands.   Keywords: hiri, small island characteristics, archipelago agriculture","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139245894","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}

Transjakarta Corridor 8 Harmoni - Lebak Bulus covers Central Jakarta, West Jakarta, and South Jakarta which are government centers and densely populated settlements. The high activity in the area causes an increase in transportation flows and greenhouse gas emissions. The transportation sector is the highest contributor to CO2e emissions in the capital city, thus reducing environmental quality, especially the greenbelt in Transjakarta Corridor 8. The assessment of ecological functions in this study consists of 7 variables, namely noise reduction, pollution reduction, air humidity, view control, glare control, direction and accident prevention. The research location is divided into 5 segments with the analysis method used, namely the assessment of ecological function aspects and the formulation of recommendations based on Hierarchical Process Analysis. The results of the assessment on ecological functions with noise-canceling variables were (Polyalthia longifolia) Glodongan Tiang, (Casuarina sp.) Spruce, (Acacia auriculiformis) Acacia, and (Archontophoenix alexandrae) Alexander Palm. The results of the pollution reduction assessment of each segment are dominated by vegetation types (Mangifera indica) Mango, (Polyalthia longifolia) Glodongan Tiang, (Carbera odollam) Bintaro. Based on the results of the questionnaire, the AHP assessment weight was obtained. The combined AHP results show the highest priority scale for the evaluation recommendations of this research is Pollution Reduction as the most important variable with a weight of 0.348, the second rank is Accident Reducer with a weight of 0.300, the third rank is Glare Control with a weight of 0.150.

The second factor was 4 types of host plant many as 4 levels: corn (Zea mays), sorghum (Sorghum bicolor. (L.) Moench), centro beans (Centrosema pubescens), and ruji beans (Pueraria javanica). Each treatment was repeated five times, so there were 60 experimental units. The spores were isolated by wet filtration and decantation methods adapted from Gerdemann and Nicolson (1963), followed by the modified sugar centrifugation method from Jenkins (1964). The observed parameter was the number of mycorrhizal spores. The data obtained were analyzed by a variance test (F test). To evaluate the treatment's effect and compare the selected treatments, Duncan's follow-up test was used at the level of 5%. The combination of the location of the shrub inoculum and the centro bean host plant showed the largest spore population, which was 222.60 per 50 g soil sample.

Therefore, this study aimed to describe farmers' perceptions regarding the causes, opportunities, and impacts of risks to develop a risk reduction strategy for salt farming in Madura Island. The study used a multistage sampling method to obtain 120 respondents and was conducted in three regencies: Sampang, Pamekasan, and Sumenep. The first objective was analyzed using the descriptive method, while the second was designed using the Kountur method. Farmers' perceptions showed that seawater quality, wind and temperature, rainfall, soil porosity, price volatility, marketing channels, government policies, capital constraints, and human resource quality could cause risks in salt farming. Several risks were perceived to significantly impact salt farming, such as government policies, partnerships, marketing channels, prices, and capital availability. Therefore, some recommendations to improve the risk reduction strategies included the use of horizontal axis windmills, revitalization of groups and partnerships, and capital strengthening through the effectiveness of the PUGAR (Empowerment of Smallholder Salt Businesses) policy by the development of standard procedures for the timely and targeted distribution of the aides.   Keywords: perception, risk, salt, strategy","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322145","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}

The objectives of this study are (1) to identify the amount of organic waste absorption with BSF larval farming business, (2) to analyze the financial feasibility of cultivation in BSF Maggot Cultivation business units in Balaraja and in Tunas, (3) to analyze business efficiency in animal husbandry and fisheries through a circular economy system in the use of BSF larval feed. The research used descriptive-quantitative analysis, financial feasibility analysis, and business efficiency analysis. The results showed that the amount of waste absorption from larval farming business activities reached 430.7 tons/year, with the total land area needed for cultivation being 137,855 m2.
