Abstract

Mulberry cultivation and silkworm maintenance are household agro-industries with short production processes, which can be done by men and women and produce quickly. The research aims to analyze the role of gender in the household of mulberry cultivation and silkworm maintenance and analyze the effect of gender roles' dominance on the sustainable livelihood of the mulberry cultivation and silkworm maintenance. This research is a qualitative descriptive with case studies in nine businesses of mulberry cultivation and silkworm maintenance in Sabbangparu District, Wajo Regency. Research informants were purposive. Data were analyzed using a qualitative approach. The results showed that gender roles in roles allocation (reproductive, social, productive), economic allocation, and power allocation were dominated by wives (consecutively 51.94%, 47.08%, and 52.48%). High-income households, wives play a dominant role in allocating the positions while the power allocation tends to be decided together (husband and wife). The dominance of gender roles (husband and wife) in households does affect the sustainability of livelihood. Therefore, the husband and wife's involvement becomes necessary so that the mulberry cultivation and silkworm maintenance can run well and sustainably.

Abstract

Drought is abiotic stress that can inhibit the growth and yield of rice plants. A simple method to determine the physiological response, growth, and yield of rice is using plant growth analysis. The aim of this research was to study the physiological characters of IPB 4S rice varieties on planting media with different drought stress levels using plant growth analysis. This research used a non-factorial completely randomized design with 6 levels of water percentage from field capacity, namely field capacity, 10% of field capacity, 20%, 30%, 40%, and 50% of field capacity. The treatment was repeated three times so that there were 18 experimental units. Observation of plant growth analysis was carried out by measuring leaf area and plant dry weight at 3 and 8 days after planting. Drought stress 20-50% of field capacity has a net assimilation rate, leaf area index, and plant growth rate 8 weeks after planting lower than drought stress at field capacity up to 10% of field capacity. In general, an increase in drought stress by 20-50% results in a decrease in net assimilation rate, plant growth rate, and leaf area index of 8 weeks after planting. This shows that the IPB 4S variety of rice plants has tolerance to drought stress up to 10% of the field capacity.

Abstract

Siderophore is an iron-chelating agent produced by plants and microorganisms under iron deficiency conditions. One of the microorganisms that ability produce siderophore is a fungus. This study aimed to determine the potential of endophytic fungi in creating siderophore. The ability of fungi to produce siderophore, especially Salicylate and Catechol using Potato Dextrose Broth (PDB) liquid media and Hathway Reagent. Eight isolates of endophytic fungi from local rice South Sulawesi have tested their ability to produce siderophore. Eight isolates of endophytic fungi before being tested were rejuvenated by growing on Potato Dextrose Agar (PDA) medium for seven days. Each isolate was grown on a PDB medium before being tested. The absorbance is measured using a spectrophotometer at a wavelength of 560 nm with Na. Salicylate 700 nm with 2.3 DHBA as standard. The results showed that the isolates of E4 and E8 had the capability to produce siderophores. The results provide the latest information regarding endophytic fungi' potential from local rice in South Sulawesi as a siderophore producer.

Abstract

Sustainable cropping systems are part of a sustainable agricultural system in a broader sense. Some of the pillars of sustainable cropping systems commonly applied in Indonesia, such as vegetation succession, polyculture systems, cropping patterns, crop rotation, are discussed in this review. Furthermore, an analysis of the sustainable cropping system model was carried out: (1). Based on shade coffee plantations that are widely applied in Indonesian coffee plantations, (2). Based on the agricultural cultivation landscape in Bali Province known as the Subak system, which UNESCO has registered as a world heritage site, (3). Based on agroforest rubber plantations which are the local wisdom of Sumatra and Kalimantan.

Abstract

Investment feasibility studies are needed to determine whether a business is feasible or not to run. The shrimp chips industry utilizes shrimp raw materials which are available quite a lot in the market. Vacuum frying is a frying process at low temperatures and pressures lower than atmospheric pressure to produce healthy and high-quality food. The research objective was to determine the feasibility of investing in shrimp chips resulting from vacuum frying and to determine the sensitivity of changes in raw material input and profit deficits. The results of the investment feasibility analysis with an interest rate of 20% using a vacuum fryer with a capacity of 6 kg per process are feasible to run according to the investment feasibility analysis parameters, namely Net Present Value (NPV) IDR 119,535,863.15; Net B/C 1.94; Payback Period (PP) 1 year 9 months; Break Event Point (BEP) for IDR 211,041,152.22 and Break Event Point (BEP) for production of 703 kg. The results of the sensitivity analysis to raw material input if it increases by 10%, the investment is feasible except for the Net B/C parameter (0.26) or less than 1, and the sensitivity analysis to profits if it decreases by 10%, indicates that the investment is not feasible to run.

Abstract

The conversion of agricultural land at a high enough rate may threaten the food security of the population. The agricultural land most vulnerable to conversion is the rice field. The aim of this study was to determine the changes in paddy fields from 2013 to 2020, the distribution of the transformation of paddy fields to other lands, and the factors that influence the conversion of paddy fields. This research was carried out by digitizing the on-screen image method in 2013 and 2020. The classification of land use results from digitization was tested for accuracy by determining the sample points in the GIS (Geographic Information System) application and then compared to the results of the field survey. In addition, an analysis of the changes in paddy fields was carried out by overlaying land use maps in 2013 and 2020. Observations and interviews with people whose land was changing were conducted on the factors affecting the change in paddy fields. Changes in land use over a period of 7 years (2013-2020), namely rice fields, decreased by 149 ha (7.36 percent ). Meanwhile, there has been an increase in the area in other land uses. The function of the paddy fields in the urban area of Pangkajene, Sidrap Regency, has become 18.69 hectares of land built, 59.42 hectares of mixed gardens, 23.13 hectares of open/empty land and 49.11 hectares of land. The factor that affects the conversion of paddy fields in the urban area of Pangkajene is the strategic location of the land, which causes the community to convert its land into a place of trade and services. The increase in the number of people requiring large land areas has led to the construction of many residential complexes in rice fields and the high selling price of rice fields, which encourages farmers to sell their land.

Abstract

Ruminant livestock development is largely determined by the carrying capacity of feed sources because the availability of quality feed is a major factor of success. The quality of natural grass that has been relied on so far must be improved by utilizing superior grass which produces better biomass and nutrients. Mulato grass (Brachiaria hybrid cv. Mulato) is one of the superior grasses that has not been widely cultivated in South Sulawesi. This study aims to look at the growth of mulato grass fertilized with different types of manure. The research design applied was a completely randomized design (CRD) with 4 treatments of giving fertilizers and 3 consecutive repetitions consisting of no treatment, administration of goat feces, treatment of cow feces, and treatment of layer chicken feces. The variables observed were plant height, plant length, number of tillers, and number of leaves which were carried out every week after being uniform. The results showed that the use of cow feces gave the best results on all variables measured in details of the best plant height 44.2 cm, plant length 68.3 cm, 70 pieces, and 11.3 tillers.
