Abstract

The tempe industry is one of the most numerous industries in Indonesia, so there is a high opportunity for making tempeh juice in the tempe industry. The application of tempeh in the manufacture of tempeh essence drink with emprit ginger extract is expected to provide benefits to the tempe industry in Indonesia. Tempe juice drink is one of the processed food products made from tempeh. Tempe juice drink is added with emprit ginger extract to remove the unpleasant aroma from tempeh and give flavor to the tempeh juice drink. On manufacture Tempe juice drink Emprit ginger extract need addition material CMC stabilizer for increase stability and viscosity product . Study This aim To determine the economic feasibility, an economic analysis was carried out regarding the feasibility of applying tempeh juice in the tempe industry.

This parameter calculates projected production, revenue and cash flow. Determination of the economic feasibility of the Tempe juice drink with Emprit ginger extract with the Net Present Value (NPV), Incremental Rate of Return (IRR), Net B/C and Pay Back Period (PBP). The assumption of drinking tempeh juice with emprit ginger extract in a year is 45600 bottles at a price of IDR 10,000.00 / bottle . The proportion of capital comes from 60% own capital and 40% credit. The average operational cost per year is IDR 278.606.467.00, variable costs Rp 233.606.467.00, and a flat fee of Rp 45.000.000.00 . Average income per year Rp 319.200,000.00 while spending Rp 304.017.802.00.  The profit earned is Rp 151.982.198. Sales profit 2 8.33 % with 15% tax per year. This business BEP occurs in sales with an average value of Rp. 151.982.198 or 33,33 % of production capacity per year. The results showed that the NPV was Rp 156.180.415, IRR is 53 %, and Net B/C is 1.82 times. Based on existing criteria or assumptions, this business is feasible to run with PBP for two years, or the capital invested in this business can be returned before the project ends (3 many years).

Abstract

Expansion of planting areas by utilizing sub-optimal land and the use of superior varieties is one of the alternatives in increasing soybean production in Indonesia. Therefore, this study aims to analyze the growth of three soybean varieties on Ultisol land in the Experimental Garden of the Faculty of Agriculture, Andalas University. This activity was conducted from September to November of 2022. The soybean varieties used in this study were Dena 1, Devon 1, and Demas 1. This research was designed using a Randomized Group Design with 1 factor, namely the type of variety with 3 groups of replications. The observation results of each treatment were analyzed statistically. If F count is greater than F table, then continued with Tukey's Further Test at the 5% level. It was concluded that some of the observed characters of the three soybean varieties showed that there were significant differences in growth in the observation of plant height and leaf area index. While in the observation of plant growth rate and the ratio of crown: root there was no significant difference between the tested varieties.

Abstract

The use of inorganic fertilizers for a long time has an adverse impact on soil quality and the environment. For this reason, an agricultural approach that uses potential natural resources is needed. One of them is by applying agriculture in an organic concept that utilizes biological materials such as mycorrhiza and the addition of maggot compost. The purpose of this study was to determine the effect of mycorrhizal inoculation and maggot compost on the development of sunflowers on marginal land. In practice, the study used a randomized block design consisting of two factors, namely mycorrhizal inoculum and maggot compost which was repeated 3 times. The results of the study showed that mycorrhizal inoculation and maggot compost had an influence on the development of sunflowers such as the time of full bloom, ribbon flower diameter, tube flower diameter, number of seeds planted and weight of 100 seeds on marginal land. the higher the dose of mycorrhiza and maggot compost applied, the increase in each parameter observed in sunflower development on marginal land.

Abstract

This study aimed to find the optimum conditions for extracting the carotenoid content in orange sweet potato in an applied application. The extracted carotenoids will be used as raw materials to produce rose-scented aromatic compounds (b-ionone). The extraction process was carried out on dry matter using maceration technique and using hexane as solvent. Other solvents such as methanol, ethanol, isopropanol and choloroform were also used to extract carotenoids from orange sweet potato. The use of wet samples and dry samples was also carried out in this study. The ratio of the solvent used with the material was 1:3. Based on the yield and spectrophotometric characterization, it was known that the extraction process with hexane solvent can extract carotenoid compounds from dry orange sweet potato powder if the extraction process is carried out 7 times

Abstract

A food self-heater is a device designed to rapidly heat food by the utilization of exothermic or endothermic reactions. To yet, a food self-heater with a dedicated scent feature has not been developed. The fragrance utilized is derived from residual tangerine peel components. The objective of this study is to investigate the variations in the concentration of the limonene compound in essential oil extracted from tangerine peel, specifically examining the impact of tangerine peel wilting. Additionally, the study intends to identify the most effective food self-heating method by incorporating tangerine peel powder as an aromatic component in the self-heating process. The present study employed a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments employed in this study encompassed varying durations of withering time for tangerine peel, denoted as A (0 hours), B (6 hours), C (12 hours), D (24 hours), and E (48 hours). The research findings indicated that the duration of drying tangerine peels had a notable impact on various factors including water content, yield, pH, color, duration for the aromatic self-heating meal to attain the optimal temperature, and aroma. However, no significant influence on limonene levels was seen. Based on the duration required for the aromatic food self-heater to attain the optimal temperature and the organoleptic aroma, treatment D (24-hour withering of tangerine peel) demonstrates the highest efficacy. This treatment exhibits a time frame of approximately 4.5 minutes for the aromatic food self-heater to reach the optimum temperature, accompanied by a fragrance rating of 4.2 in the organoleptic analysis.

Abstract

The objective of this study is to investigate the distinctive properties of activated carbon derived from cocoa pod husks that have been activated using various activators. The study seeks to assess the absorption capacity of the resulting activated carbon for the heavy metal Fe, and to identify the most effective activator for this purpose. The activators used were ZnCl2, H3PO4, KOH, and MgCl2 each at a concentration of 10%. The characteristics of the activated carbon produced include; yield 70.18–82.24%, water content 0.75–2.25%, ash content 3.50–11.00%, part lost on heating 950? or volatile matter 9.38–15.61 %, pure activated carbon of 76.94–79.16%, and absorption of iodine of 574.36–628.30 mg/g. The utilization of activated carbon derived from cocoa pod husks has demonstrated its efficacy in the adsorption of the heavy metal iron (Fe) present in well water. This adsorption process exhibits a notable absorption capacity within the range of 0.0967–0.0991 mg/g, accompanied by a high absorption efficiency ranging from 96.62% to 99.02%. The most effective activator, as determined by its iodine number, was found to be potassium hydroxide (KOH), which exhibited an impressive absorption capacity of 628.30 mg/g of iodine. On the other hand, magnesium chloride (MgCl2) emerged as the most economically viable activator, with a price of Rp. 30,00 per gram.
