The Rice Marketing System in Tidal Farming: A Case Study of Banyuasin Regency
Full text linkRice is a commodity that frequently has issues with its marketing strategy. The challenge with rice marketing in tidal areas is the lengthy marketing chain, which makes it inefficient. This study intended to (1) describe the rice marketing system, (2) identify the elements that farmers and marketing institutions evaluate when selecting transaction partners, and (3) determine the efficiency of rice marketing channels. The research was carried out in Banyu Urip Village, Lago District, Banyuasin Regency, using a survey with sampling approach. The analysis method was descriptive, with a focus on marketing efficiency, margins, and farmer shares. The results demonstrate that the rice marketing channels in the rice producing areas during the ebb and flow were separated into three channels: (a) Channel I = Farmers → Collectors → Wholesalers → Retailers → Consumers; (b) Channel II = Farmers → Collectors → Wholesalers → Consumers, and (3) Channel III: Farmers → Collectors → Retailers → Consumers. Farmers and marketing institutions evaluated the following factors when selecting trade partners: (a) Farmers are bound by debt, price, and emotional relationships; (b) Collectors are concerned about grain prices and quality. (c) Wholesalers: rice price and quality, as well as customer ties, (d) Retailers: rice price and quality, payment procedures, and customer ties. All marketing channels are effective, but the most efficient is Channel III (Farmers → Collectors → Retailers → Consumers).

Effect of Incubation of Coconut Coir Biochar and Liquid Organic Fertilizer on Nutrient Uptake of Mustard Samhong King (Brassica rapa subsp. chinensis)
Full text linkGreen mustard greens. Samhong King variety (Brassica rapa subsp. chinensis) is a popular vegetable in Indonesia. Green mustard greens have the advantage of being able to grow in both low and high elevations. The application of biochar in soil can help to improve its chemical qualities. The study employed a factorial randomized block design with two components. The treatment factor was the incubation duration of coconut fiber biochar at four levels: control, two weeks, four weeks, and six weeks. The amount of liquid organic fertilizer applied at four different levels: 1 mL/L water, 2 mL/L water, 3 mL/L water, and 4 mL/L water.The study found that coconut fiber biochar and liquid organic fertilizer had no significant effect on nutritional absorption in plant tissue or Samhong King mustard plants, however they did have the highest absorption of K, P, and N nutrients. The incubation period of coconut fiber biochar and liquid organic fertilizer had no significant effect on Samhong King mustard plant production, but the coconut fiber biochar treatment with a 6-week incubation period produced the highest yield, 2.96 t/ha. The treatment of liquid organic fertilizer yielded the best results.

Circular Economic Analysis of Black Soldier Fly Maggot Cultivation as Local Chicken Feed
Full text linkWaste management is still a significant challenge in Indonesia; organic waste is the most abundant type of waste on a national scale. A potential solution to this problem is to utilize black soldier fly (BSF) larvae as a bioconversion agent for organic waste. The purpose of this study is to determine how much organic waste is absorbed by BSF maggots, to determine the financial feasibility of BSF maggots as local chicken feed, and to analyze the efficiency value of BSF maggot cultivation in a circular economic system. The study utilized four distinct growing media: P0 = 100% kitchen organic waste (KOW); P1 = 100% cow dung; P2 = 50% KOW, 50% cow dung; and P3 = 50% KOW, 50% dairy waste. The analysis used in this study is descriptive-quantitative, and economic analysis is carried out by comparing the processes of drying, grinding, and mixing local chicken feed. The total amount of decomposable organic waste is 237 kg. Media grows P3, which is the most profitable for BSF maggot cultivation. Maggot meal production is worth developing based on the payback period and R/C. P1 can help the composting process, and production costs are efficient. The processing of maggot flour into local chicken feed is a lucrative venture, as evidenced by the potential profits it generates. This research underscores the significance of implementing a circular economy with BSF maggots in decomposing organic waste and its utilization as an ingredient in chicken feed.

House Yard as a Productive Landscape during the Covid-19 Pandemic in Metro Municipality, Lampung Province
Full text linkThis house yard (pekarangan) research was conducted at three sites of the Way Seputih-Sekampung watershed, which are represented by the upstream (Mulyosari Village), middle (Margodadi Village), and downstream (Tejosari Village), Metro Municipality, Lampung Province from May to July 2022. The objective of this research is to analyze the yard as a productive landscape by analyzing: 1) plant composition, 2) the diversity of plant species, and 3) utilization of the yard. Surveys and questionnaires were used. The number of yards was determined by purposive sampling, totaling 30 yards belonging to members of the Women Farmers’ Group (KWT) at each location. The results showed that horizontal diversity includes ornamental, fruit, vegetable, medicinal, and starch-producing plants. Sixteen types of plants were frequently found in 46% of yards. It was found that the Shannon-Wiener species diversity decreased from upstream to downstream, that is, upstream (2.41), middle (2.33), and downstream (1.82). Although the diversity of plant species is moderate on average, communities use their yards according to their function. The community was aware of the benefits of the yard, particularly its contribution to environmental sustainability, as indicated by the assessment index for the upstream (87%), midstream (93%), and downstream (94%) sites. Thus, the yard is very useful for the community as a place for interaction during the Covid-19 pandemic. Such benefits are said to be better if landscape management is carried out in a planned and environmentally friendly manner.

The Linkage of Soil pH, Phosphorus Availability, and Exchangeable Aluminum in Andisol and Recommendations for Soil Improvement
Full text linkThe Indonesian government implemented a program known as the Food Estate in Humbang Hasundutan to enhance food security. This initiative involved cultivating strategic food commodities on large-scale agricultural land. The soil type in this area is classified as Andisol, which is naturally fertile. Nevertheless, the food and horticultural crop practices in Andisol scarcely consider soil health, fertility, and sustainability. This study was conducted on the Andisols of Humbang Hasundutan to determine the limiting factors of soil chemical properties to support sustainable land management. Soil samples were collected from the topsoil layer (0-30 cm) at 95 locations using a grid-based sampling system. These samples were analyzed for pH, phosphorus availability, and exchangeable aluminum. The data were examined through correlation tests, with soil improvement levels identified using K-means clustering. The results showed that the Andisols in Humbang Hasundutan had an acidic pH level (5.30), extremely high organic carbon content (8.23%), moderate total nitrogen level (0.44%), extremely low potential and available phosphorus levels (12.66 ppm and 4.15 ppm), very low base saturation (6.48%), and relatively high exchangeable aluminum (Alexch) (1.03 cmol.kg-1). Correlation analysis revealed a negative relationship between pH and P availability, while Alexch showed a positive correlation with P availability. However, P availability in Andisol was not significantly influenced by variations in Alexch or soil pH. Soil improvement recommendations were categorized into three groups: 60 locations requiring very high P fertilization, 28 locations requiring high P fertilization, and 7 locations requiring moderate P fertilization, along with the application of soil amendments, such as dolomite or guano phosphate, to reduce aluminum levels.

Effect of Different Coconut Water Concentrations on the Growth of Dendrobium spectabile (Blume) Miq. Planlet on MS Media
Full text linkDendrobium spectabile is an orchid with unique flowers that are vulnerable to exploitation. Tissue culture is employed to conserve this orchid, where the type of medium and organic supplements significantly affect plantlet growth. Murashige and Skoog (MS) media was added with coconut water as an exogenous hormone source. This study aimed to determine the effect of adding coconut water and determine the optimal concentration to increase the growth of D. spectabile at the subculture stage. The method involved subculturing D. spectabile plantlets in vitro in MS media supplemented with coconut water at concentrations of 0%, 5%, 10%, 15%, and 20%. The research design used a completely randomized design (CRD), with coconut water concentration and ten replicates. Data were analyzed using ANOVA and Duncan\u27s Multiple Range Test at a 5% significance level. Plantlet growth was observed for two months, and the parameters observed were the emergence of new shoots, leaves, and roots; the number of new shoots, leaves, and roots; and the length of new leaves. The results showed that the addition of coconut water to the subculture medium can increase the leaf growth of D. spectabile orchid plantlets but does not increase shoot and root growth. Coconut water 10% was the most optimal concentration for the number of new leaves and new leaf length. The addition of 15% coconut water was the most optimal concentration for plantlet new leaf emergence. Coconut water plays a vital role in in vitro culture, supporting the various growth processes of D. spectabile plantlets.

Implementation Strategy of Indonesia Sustainable Palm Oil (ISPO) Certification: A\u27WOT Analysis Approach
Full text linkThe Indonesian Sustainable Palm Oil (ISPO) program was established in 2011 in response to the adverse environmental impacts caused by the expansion of palm oil production in Indonesia. To date, the ISPO implementation in Jambi Province is still relatively low. This is because there are many weaknesses and challenges in implementing the ISPO. This study aimed to identify implementation strategies for sustainable palm oil certification in Jambi Province. This analysis uses the A\u27WOT approach, which integrates the Analytical Hierarchy Process (AHP) and SWOT analysis. Based on the A\u27WOT analysis, 23 external and internal factors were obtained, which are strengths, weaknesses, opportunities, and threats. In addition, the A’WOT analysis results show that the priority strategy that can be implemented is to involve MBKM (Merdeka Belajar-Kampus Merdeka, Freedom of Learning-Independent Campus) students in helping farmers. This strategy is because independent smallholders\u27 understanding of ISPO is low and the number of ISPO extension workers or assistants is also limited. Therefore, the choice of strategy that can improve understanding of ISPO implementation is to involve MBKM students to help provide counseling and understanding related to ISPO.
