The Perceptions and Risk Reduction Strategies of Small-Scale Salt Farmers on Madura Island
Get PDFSalt farming is considered a risky venture due to the influence of both internal and external factors. Therefore, this study aimed to describe farmers\u27 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\u27 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.

Pemanfaatan Bioarang pada Beragam Cekaman Air untuk Ketersediaan Fosforus Guna Meningkatkan Produktivitas Kedelai Anjasmoro (Glycine max L. Merrill.)
Get PDFFrom 2021 to 2023, national soybean production has generally decreased due to shrinking cultivation areas. This study aimed to evaluate soybean productivity by applying biochar and regulating water volume. The experiment was conducted in the greenhouse of the Kuningan Soil Laboratory in April–November 2022 using a two-factor Complete Group Randomized Design; the first factor was the biochar dose (0, 10, 15, and 20 tons/ha), and the second factor was the water volume (50% (600 mL), 100% (1200 mL), and 125% (1800 mL). The physical parameters observed were moisture content and texture. The chemical parameters observed include pH, C-organic, cation exchange capacity (CEC), base cations (Ca, Mg, K, Na), N-total, P-total, and P-available. The data were analyzed using analysis of variance followed by Duncan\u27s Multiple Range Test to compare between treatments. The results showed that applying biochar with a dose of 20 tons/ha and 100% water volume can significantly improve soil chemical properties. pH, CEC, Ca-available, Mg-available, K-available, N-available, P-total, P-available, and N-total are markedly affected by the correct biochar dose and water volume. The more applications of biochar, the better the chemical properties of the soil. The provision of water according to needs will increase the availability of nutrients for plants.

Perubahan Morfofisiologis Tanaman Terung pada Kondisi Muka Air Tanah Dangkal dan Tergenang di Fase Generatif
Get PDFUnder suboptimal conditions, plants generally respond differently to survive. Plant responses include changes in morphology, anatomy, and physiology. This study aimed to investigate the response of eggplant to lack of oxygen due to shallow water table and waterlogging in the generative stage and explored their adaptability to be cultivated in riparian wetlands. This research was conducted from October 2017 to January 2018 in an experimental pond in the village of Demang Lebar Daun Palembang and at the Postgraduate Integrated Laboratory, Faculty of Agriculture, Sriwijaya University, Palembang. This study used a randomized block design with a shallow water table and waterlogging treatments: control (field capacity), water tables of 13 cm, 8 cm, and 3 cm below the soil surface (bss), and waterlogging 2 cm above the soil surface. The results showed that the water table 3 cm bss and waterlogging decreased the relative rate of leaf expansion, specific leaf fresh weight, and specific leaf water content. On the sixth day of the waterlogging treatment, the chlorophyll content decreased by 31.29%. On the other hand, the proline content in the leaves reached the highest level of concentration. After the sixth day, the chlorophyll content increased while the proline content decreased, and the eggplant recovered. Water table 3 cm bss and waterlogging caused the formation of aerenchyma tissue in the roots, which started one day after the treatment. Eggplant is an adaptive crop with a fairly high tolerance for shallow water tables and waterlogging.

Strategi Pengembangan dalam Pemenuhan Konsumsi Pangan Sivitas Yayasan Permaculture
Get PDFEfforts to fulfill food consumption tend to pay little attention to ecosystem sustainability. Permaculture is an agricultural system that designs landscapes resembling natural ecosystems so that they can produce food and prioritize the principle of sustainability. However, as the population increases, permaculture must be reviewed to meet food consumption. This research is a case study in YS Permaculture that implements a permaculture farming system to meet the food consumption needs of the foundation\u27s community. The purpose of the study is to identify the principles of permaculture in the empirical conditions of the foundation and formulate a development strategy to meet the food consumption of the foundation community. This research uses a qualitative descriptive method using an in-depth interview method with foundation management. Based on the identification of 12 permaculture principles, one principle still needs to be implemented optimally, namely, using and respecting renewable resources and their functions. Strategic steps that can be taken to increase the productivity of food commodities and fulfill food consumption are the extensification of permaculture gardens and the implementation of regenerative agriculture that integrates artificial intelligence, machine learning, and precision agriculture. The strategy of fulfilling food consumption for the foundation community through permaculture requires cooperation with various parties, including the government and academics, related to strengthening food security while still paying attention to environmental and social aspects.

Pengaruh Pemberian Kompos Pada Pertumbuhan dan Produktivitas Tanaman Bawang Merah (Allium cepa L.)
Get PDFShallot productivity relies on diverse environmental conditions, including soil fertility. Compost is an organic material that is crucial for the improvement of soil health and fertility. Compost amendment could be employed on shallot to improve its growth and productivity. This study aims to investigate the effect of 4 different composts amendments, processed with 4 different bioactivators, on the shallot growth (Bima–Brebes variety), the dynamic of culturable microbes, and nutrient content on the growth medium inside the polybag. Treatments include a mature compost processed with no biactivators (K0), and with the bioactivator Bioaktimo (K1), Beyonic Startmik (K2), indigenous (K3), and the mixed of K1, K2, and K3 (K4). Measured parameters on shallot growth include plant height, number of leaves, stem diameter, wet and dry weights of shallot bulb, root, and above-ground biomass, and chlorophyll content. In addition, physical, chemical, and biological characteristics of the initial planting medium on the polybag were determined. The result showed that compost amendment significantly increased all parameters tested, except chlorophyll content, when compared to the control and the treatment with 100% chemical fertilizer. The best shallot growth was found in the treatment with soil planting media of 75% Soil + 25% Compost K4 (TK5).

Perbanyakan Mikoriza Indigenus Taman Nasional Gunung Ciremai dengan Berbagai Tanaman Inang
Get PDFThis study aimed to determine the effectiveness of the use of host plants in an effort to multiply mycorrhizal propagules indigenous to Gunung Ciremai National Park. The experimental method used a factorial complete randomized design with 2 factors. The first factor was the location of the source of inoculum by 3 levels: mixed forests, shrubs, and pine stands. 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\u27s effect and compare the selected treatments, Duncan\u27s 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. Trapping techniques using host plants of corn, sorghum, centro beans, and ruji beans showed suboptimal results. The most common genera were Glomus (80%; 4 species), Gigaspora (10%, 1 species), and Acaulospora (10%, 1 species). Glomus was evenly found in all trapping results.
