Abstract

Banana leaves belong to the waste products of the banana plant and are a potential source of liquid smoke due to their abundance, containing 10.85% cellulose, 19.95% hemicellulose and 18.21% lignin. Liquid smoke has many uses, including as an antibacterial agent and food preservative. The purpose of this study was to identify the characteristics of the liquid smoke from redistilled dried banana leaves. The process of making liquid smoke by pyrolysis, precipitation, distillation, and adsorption with activated zeolites. Liquid smoke is then physically observed for color and flavor, tested for compound content using GC-MS tests, and analyzed descriptively. The results showed that the liquid smoke from redistilled dried banana leaves had a mild taste and pale yellow color. was found to contain 13.09% area, carbonyls in 1.42% area, and no HPA compounds..

Abstract

The aim of the study was to obtain second generation mutant lines (M2) from three gene-mutated soybean seeds, namely M2 Anjasmoro, M2 Argomulyo and M2 Dena-1 which are tolerant to drought stress, water saturation stress and high yield potential. The research was carried out in the Maros district, South Sulawesi, July-November 2022, arranged in a split plot design. The main plot is the application of water consisting of three levels, namely selection of drought stress (C1), selection of water saturation stress (C2) and selection of optimum conditions (C3). Subplots are three second generation soybean seeds resulting from gene mutations (M2), namely: M2 Anjasmoro, M2 Argomulyo and M2 Dena-1. The results showed that the best plant agronomic characters for growth and production factors were M2 Anjasmoro for water saturation stress treatment and M2 Argomulyo and M2 Dena-1 for drought stress treatment. The fastest harvesting age was obtained from the combination of drought stress and M2 Argomulyo, namely 79 days and not significantly different from the combination of drought stress and M2 Dena-1, namely 79.34 days, but significantly different from the other treatment combinations. The production obtained from the seeds resulting from the second generation of gene mutations has begun to show a difference between those given the mutation treatment and their parents, where the combination of water saturation stress and M2 Anjasmoro gave the highest production of 3.20 tonnes/ha higher than the production of its parents which only reached 2. .03-2.25 tonnes/ha. Generation M2 Argomulyo seeds were the longest surviving seeds to recovery from drought stress (38 days), in the sense that M2 Argomulyo seeds were more resistant to drought stress than the other two generations of seeds, namely M2 Anjasmoro (36 days) and M2 Dena-1 (37 days). Meanwhile, the resistance to water saturation was shown by M2 Dena-1 generation seeds, namely 40.67 days, followed by M2 Argomulyo 29.67 days and M2 Anjasmoro 27.33 days.

Abstract

The purpose of this study was to determine the effect of temperature on the pasteurization process of ohmicheating method on chemical, physical, microbiological, and ogranoleptic characteristics of lemon juice. Thisstudy used a simple linear regression method with application SPSS version 25. Simple linear regression testdecision making can refer to two things, namely comparing the significance value with the probability value of5%. The response in this study includes the chemical response is protein levels. Physical responses carried outinclude color using colorimetric methods, viscosity, and specific gravity. Microbiological responses include totalplate count (TPC). Organoleptic response is a hedonic test of aroma, taste, and aftertaste. Based on the results of the study, it shows that there is an influence of temperature on the characteristics of lemon juice that has beenpasteurized on the Line Process machine using the ohmic heating method, namely protein content, viscosity, specific gravity, color, and total microbes. Temperature also affects the level of preference for organolepticresponses to the attributes of aroma, taste, and aftertaste.

Abstract

The increasing volume of market waste that continues to occur makes people think negatively of waste, but on the other hand waste can provide positive things by composting. The purpose of this research is to analyze the content of Water Holding Capacity (WHC) in organic compost made from market waste. The composting process uses the Open Windrow method with aerobic Composting Bag container media. Composting was carried out for fifteen days with variations in the addition of bioactivators to accelerate the maturation of different composts are 50 ml, 75 ml, 100 ml, 125 ml, and 150 ml with one control compost. The bioactivator used is a type of local microorganism (MOL) made from market waste. Based on the results of this study, compost with a variation of 150 ml bioactivator addition produced an optimal WHC content of 75%, the best water content of 49.24%, C/N 15.57%, temperature 32.29°C, and pH 7.

Abstract

Cooperatives can potentially have a broad impact on the economic order. The success of cooperatives can benefit members, the surrounding environment, and even the broader scope. The agricultural sector is the third largest number of cooperatives in Lampung Province. This research aimed to analyze the factors that affect cooperative business volume, and net income (SHU) of agricultural sector cooperatives in Lampung Province. The number of samples in this study was 33 cooperatives. The samples are cooperatives that run agricultural related businesses and cooperatives whose members are agricultural business actors in Lampung Province. The multiple linear regression was used to analyze factors that influenced the business volume and the net income (SHU). It was found the number of members and business units have a negative effect on business volume, while capital and loan capital have a positive effect on business volume. At the same time, the variables of managers' availability and the chairman's education level do not affect the business volume of agricultural sector cooperatives in Lampung Province. Self-capital, loan capital, and the chairman's high level of education have a positive effect on business rest, and the number of members and business units have a negative effect on the net income (SHU). In contrast, the manager availability and the chairman’s education level at imtermediate and low levels have no effect on the net income (SHU) of agricultural sector cooperatives in Lampung Province. Keywords: agricultural cooperatives, business volume, net income (SHU)
