Abstract

The increasing use of synthetic polymer-based plastics derived from non-renewable resources has caused serious environmental and health problems. Therefore, the development of bioplastics based on natural polymers is considered a sustainable solution. This study aimed to isolate cellulose from lontar fruit fiber (Borassus flabellifer Linn.) and to evaluate its potential application as a raw material for bioplastic production. Lontar fruit fiber was subjected to alkaline treatment using NaOH, followed by bleaching with H₂O₂ and acid hydrolysis using H₂SO₄. The isolated cellulose was characterized in terms of yield, moisture content, and functional group identification using Fourier Transform Infrared (FTIR) spectroscopy. The results showed that the final cellulose yield reached 45.67%, indicating the dominance of the cellulose fraction after significant removal of hemicellulose and partial lignin. FTIR analysis confirmed the presence of characteristic cellulose functional groups, including hydroxyl (–OH), C–H stretching, and β-1,4-glycosidic (C–O–C) bonds, while lignin-related absorption bands were observed with very low intensity. The isolated cellulose was subsequently applied in bioplastic formulation using gelatin and glycerol as plasticizers. The resulting bioplastic exhibited homogeneous appearance, good elasticity, and low brittleness. These findings demonstrate that cellulose derived from lontar fruit fiber has strong potential as an environmentally friendly bioplastic raw material and supports the valorization of local biomass waste from dryland ecosystems.

Abstract

Penelitian ini bertujuan untuk mengetahui kadar NPK, asam amino dan fitohormon pada ekstrak keong mas yang difermentasi menggunakan EM4 (Effective Microorganism 4). Penelitian ini dilakukan dengan cara menambahkan EM4 aktif yang terdiri dari 6 level konsentrasi (0%; 5%; 10%; 15%; 20%; 25%) dan air gula ke dalam reaktor yang berisi ekstrak keong mas. Proses fermentasi dilakukakan selama 14 hari. Selanjutnya dilakukan pengambilan sampel pada hari ke 0 dan hari ke 14 untuk dianalisis kandungan hara makro yang terdiri dari N-total, P2O5 dan K2O, kandungan asam amino dan fitohormon dengan metode Kjeldhal dan LCMS. Hasil penelitian menunjukkan bahwa kadar N-total dan Kalium berbeda sangat nyata, dimana terjadi penurunan kadar N total dari ekstrak keong mas pada beberapa konsentrasi EM4 aktif selama proses fermentasi, kandungan Nitrogen paling tinggi terdeteksi pada fermentasi tanpa EM4 (0%), yaitu sebesar 1,766 % (v/v). Kadar Nitrogen paling kecil pada fermentasi menggunakan 25% EM4 aktif yaitu sebesar 1,474%. Sedangkan kandungan fosfor tidak mengalami penurunan kadar secara signifikan selama fermentasi 14 hari pada semua perlakuan. Semakin bertambahnya konsentrasi EM4 aktif, terjadi penurunan pada 12 jenis asam amino dari ekstrak keong mas segar. Kandungan Sitokinin dan Giberelin tidak teridentifikasi, sedangkan IAA (Indole asetic acid) terjadi peningkatan selama proses fermentasi 14 hari pada semua perlakuan.

Abstract

This study aims to inventory the plants used by farmers in West Sumatra to make vegetable pesticide ingredients and determine their effectiveness and to formulate botanical pesticides based on their effectiveness in killing insects. Data collection was carried out by direct interviews with farmers. Testing the active substance content of vegetable pesticides is carried out by means of a phytochemical test in the laboratory. The effectiveness of the plant extracts from the inventory was tested in the laboratory. Testing the effectiveness of botanical pesticide formulations is carried out in the field. Formulation effectiveness data were observed qualitatively by farmer groups from the number of leaf vegetables eaten by caterpillars or insects for approximately 2 weeks. There were 44 (forty four) species of plants used by farmers as ingredients for making vegetable pesticides, and 20 (twenty) species of phytochemical tests were carried out, followed by 17 (seventeen) species of effectiveness tests. Formulas for vegetable pesticides are made based on the results of laboratory extract effectiveness tests. The results of the study showed that plants that were effective as ingredients for vegetable pesticides were surian, neem, karakok, citronella which were made with the following formulations: Formula 1 (Surian and Karakok), Formula 2 (Surian, Mindi, Karakok), Formula 3 (Mindi and Karakok) , and Formula 4 (Surian, Mindi, Karakok, Lemongrass Wangi). The results of the effectiveness test of the botanical pesticide formulas in the field showed that the F2 and 4 formulas were more effective than the F1 and F3.

Abstract

Floating agricultural cultivation is one of the right solutions for carrying out shallot cultivation in swamp areas. The aim of this research is to determine the effectiveness of sulfur application on the agronomic characters, morphology and phytochemical content of shallots (Allium ascalonicum L.). The research was carried out in May 2023 at the research pond of the Faculty of Agriculture, Sriwijaya University. The method used in this research was a completely randomized design with sulfur applications including : S1 (0 kg ha-1), S2 (30 kg ha-1), S3 (60 kg ha-1), S4 (120 kg ha-1), S5 (240 kg ha-1). The results of this research were that giving 60 kg ha-1 of sulfur to floating shallots had the best effect on the number of leaves, leaf length, crop growth rate, wet weight, and leaf chlorophyll content. Antioxidant activity can be predicted well from the additional sulfur dose in floating cultivation (R2: 89%) with an estimated optimum sulfur dose of 82.4 kg ha-1, 92.5 kg ha-1, and 134.5 kg ha-1. Air dry tuber weight can be predicted moderately (R2: 65%) with estimated optimum sulfur doses of 93 kg ha-1 and 79.3 kg ha-1.

Abstract

Coffee is a leading plantation commodity in Garut Regency. This study aims to analyze business feasibility from non-financial and financial aspects, as well as to assess the level of sensitivity and substitute value analysis to fluctuations in raw material prices. The method used is descriptive quantitative, focusing on analyzing the business feasibility from non-financial and financial aspects. Non-financial aspects included market, technical, management and legal, social, economic and cultural, and environmental aspects. Financial aspects were analyzed using cash flow and investment criteria such as NPV, Gross B/C, Net B/C, IRR, and PP. In addition, sensitivity analysis and surrogate value analysis were also used. Translated with DeepL.com (free version). The results of the business feasibility analysis from non-financial aspects show that this business is feasible despite the shortcomings in the technical aspects, which can be offset by market and environmental aspects. From a financial perspective, the Talaga Hurip Arabica Coffee processing business is also declared feasible, with an inflow of Rp 52,800,000 resulting from the sale of 240 kg of coffee at a price of Rp 220,000/kg. Outflow includes investment costs of Rp 69,942,000 with depreciation of Rp 7,565,725/year, fixed costs of Rp 11,107,000/year, and variable costs of Rp 25,050,400/year. The investment feasibility criteria in this study show an NPV of IDR 24,042,745, Gross B/C of 1.09, Net B/C of 1.55, IRR of 24.65 percent, and PP of 6.1 years, which means that the Talaga Hurip Kopi business meets all investment feasibility criteria. However, the sensitivity analysis shows that if coffee prices increase by more than 10 percent, the business will not be viable. Translated with DeepL.com (free version).

Abstract

Lamb processing as a culinary choice is less prevalent in Indonesia than processing from similar livestock. Lamb meat also has a nutritional value comparable to that of processed meat. On the other hand, lamb meat is more easily damaged, so it needs to be processed to get a longer shelf life, for example, by making it into shredded lamb. The form of shredded meat is practical, can be enjoyed at any time, and is commonly used as a filling for other food products such as bread. This study aims to determine shredded lamb's chemical characteristics and consumer acceptance of shredded lamb as a filling in floss roll bread products. The test parameters include chemical parameters (moisture content, ash, fat, protein, carbohydrates), with each repeated three times, and sensory parameters (texture, taste, color, aroma, and whole). The data analysis used Anova Oneway for chemical parameters and simple calculations for organoleptic parameters. The results showed the moisture content of lamb shredded meat (4.875%), ash (5.80%), fat (18.86%), protein (10.20%), and carbohydrates (60.27%). The organoleptic test of shredded lamb showed the average preference of the panelists as a whole with a score of (3.8), which was between Neutral-Like. On the floss roll bread, the average favorite of the panelists was a score of (4.2) in the Like – Very Like category. It can be concluded that the value of water, ash, and fat content of lamb shredded meat has met the quality requirements of SNI (1995), except for the protein value. This shredded lamb product has a great chance of having a long shelf life, and its use as a filling on floss roll bread is more acceptable than the assessment of single shredded lamb.

Abstract

The rice cultivation system developed in Lampung Province is still conventional, but community groups in Rejoasri Village, Seputi Raman District, Central Lampung Regency have begun to develop which have implemented sustainable agricultural practices, namely PP Gapsera Sejahtera Mandiri. One of the rice produced has the advantage of non-chemical pesticide rice. The problem faced by the value chain actors of the rice milling agroindustry business is that the business does not operate continuously due to limited stock of grain raw materials, this is due to the fact that business actors have limited warehouse capacity, limited capital, and poor marketing management. Constraints in marketing also cause the Company's cash flow to also be disrupted. For this reason, it is necessary to study whether the rice milling business of PP Gapsera Sejahtera from the market and financial aspects is feasible or not developed. The goal of this study is to analyze the marketing and financial feasibility of the PP GSM paddy rice milling business. The analysis method used is descriptive analysis of rice marketing and investment feasibility analysis using Net Present Value (NPV), Net Benefit Cost ratio (Net B/C ratio), and Internal rate of return (IRR) analysis. The results of the study show that from the marketing aspect, the rice milling business is feasible to be developed. This can be seen from the marketing pattern of Berasera rice has 3 patterns, the rice sold has the advantage of having the "Berasera" brand, namely; Rice without chemical pesticides, has a certificate from Sucofinda Rice is free of chemicals and a halal certificate. Selling prices are competitive in the market and have paid attention to the production costs incurred. The promotion strategy is carried out directly through exhibitions, social media, the Shopee marketplace, and the PP gapsera website. The distribution strategy is carried out through several patterns from producers, agents, retailers (shops/supermarkets), with the aim of expanding the rice marketing network. Judging from the financial aspect, rice milling is worth developing, because the NPV value is > 0. Net B/C ratio > 1, and IRR > The applicable bank interest rate of 7%.
