Abstract

The aim of this study was to determine the effect of seeding media, the time difference in NPK fertilizer application, and the responses between the two on the growth of pepper cuttings. The first factor is the composition of the planting medium, consisting of a mixture of river sand + husk charcoal, river sand + compost, husk charcoal + compost, and river sand + husk charcoal + compost. The second factor is the application time of NPK fertilizer (P) which consists of 2, 4, 6, and 8 weeks after planting. The initial condition of the cuttings at the initial fertilization was 2 MSPT, namely the age of 35 DAS. The experiment was repeated 3 times and each experiment consisted of 2 seeds. The homogeneity of the inter-treatment variance used the Bartlett test and the additivity of the data with the Tukey test was followed by an orthogonal comparison test of contrast and polynomial at the ? 5% level. The results showed that the best nursery media for the growth of pepper cuttings were river sand + compost on 4, 8, 12 MSPT leaves, fresh weight, and shoot dry weight. In addition, the time of application of NPK fertilizer to the growth of pepper cuttings did not differ in all observed variables. The results also showed that there was an interaction between the nursery media and the time of NPK fertilizer application on the growth of pepper cuttings. The use of river sand media + husk charcoal was linear with the addition of 1 MSPT NPK fertilizer application time and increased the total number of roots by 2.0 roots. Media sand times + husk charcoal + compost at the time of the optimum application of 5.2 MSPT NPK fertilizer produced the highest number of roots is 18.92 roots.

Abstract

The household income comes from the income of fishermen's household groups (husband, wife, children, and other family members) and works (fishers and non-fishermen). The amount of household income strongly influences the consumption pattern of anglers households. This study aims to analyze the amount of income, food consumption patterns, and the relationship between income and the model of fishermen household food consumption. The population in this study were all fisherman households in Panyula Village, East Tanete Riattang District, Bone Method District. The research's location was carried out purposively, considering that the area is mostly coastal areas, and the livelihood of the community is fishermen. Determining the sample of 10% using a simple random method (simple random sampling), so the number of samples selected is 50 fisherman households. Data were analyzed using the method of income analysis, expected food patterns (PPH), and Chi-square. The results showed that the income structure of fishermen's household originated from the husband's income of 60.3%, the wife 3.8%, the children 30.4%, and the profit of other family members 5.5%. Sources of income based on the type of work, namely from work as fishermen, amounted to 80.5% and alternative jobs other than fishers by 19.5%. The pattern of fishermen's household food consumption based on the Expected Food Pattern is 90% in the shallow category, and there are no respondents insufficient and proper groups. The relationship between income and household food consumption patterns of fishers is not significant.

Abstract

This study aims to evaluate the growth and production of hybrid maize on ultisol soils using biochar and chicken manure to support sustainable agriculture. This study used a factorial design based on the randomized block design, which consisted of two treatment factors and three replications. The first factor is the dosage of biochar consisting of 4 levels, namely without biochar (control), 0.25 kg.m-2; 0.5 kg.m-2; and 1 kg.m-2. The second factor is the dose of chicken manure, consisting of four levels, namely without chicken manure (control), chicken manure with a dose of 0.25 kg.m-2; 0.5 kg.m-2; and 1 kg.m-2. The results showed that biochar treatment had a significant effect on plant height. The interaction between treatments has a significant effect on the weight of the ear without the cob. The best biochar treatment was at a dose of 0.25 kg.m-2 while the best treatment of chicken manure was at a dose of 1 kg.m-2.

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

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.
