THE GREENHOUSE GAS ANALYSIS USING LIFE CYCLE ASSESSMENT (LCA) IN SMALL SCALE TOFU INDUSTRY

2024-09-05T15:00:38+07:00

The tofu industry is one of the industries that has grown and developed a lot in Indonesia to meet the community's food needs. In the tofu production cycle, many activities have the potential to produce emissions that are harmful to the environment, one of which is greenhouse gases (GHGs). There are various activities carried out by the tofu industry to produce products that are ready for sale, starting from the procurement of raw materials, the production and distribution of tofu to the market. The longer the tofu production chain, the greater the potential to produce GHG emissions. To find out the amount of GHG emissions produced, it is necessary to take a tofu product life cycle (LCA) assessment. Therefore, this study aims to calculate the GHG emissions produced in the tofu production cycle in the X’s tofu industry. The results show that X’s tofu industry produces GHG emissions of 3,373.53 KgCO_2eq per 300 kg soybean which originate from the use of electricity, gasoline, firewood, and liquid waste. Every activity carried out also contributes to the emergence of GHG emissions. The highest GHG comes from the use of firewood of 3,198.81 KgCO_2eq, meanwhile, the stage that generates the most GHG is during the cooking stage. Alternative improvements that can be made to reduce emissions are minimizing the use of transportation equipment, minimizing water usage (water reduction), water reuse, converting the use of firewood to LPG, and utilizing liquid waste into biogas for the cooking process.

2024-09-05T14:38:58+07:00

Sunflower (Helianthus annuus L.) has the potential for high added economic value to be developed. Indonesia has the opportunity to develop a sunflower agro-industry which is processed into cooking oil. There has not been much research related to the sunflower agro-industry supply chain. A plan for improvements to the supply chain cannot yet be carried out, because the situation in the supply chain has not been comprehensively elaborated. Therefore, this research aimed to analyse the situational supply chain of the sunflower agribusiness. The method used was soft system methodology developed by Checkland. This research has succeeded in designing a conceptual model that produces two human activities, namely: 1) Development of production devices for the drying process of sunflower seeds based on the Internet of Things, (2) Utilization of the Blynk application to support the decisions on the sunflower agro-industry supply chain network, and (3) Development of the prototype digital platform decision support system on the production device based on internet of things. These three activities are also recommendations given as corrective actions to increase the productivity of the sunflower agro-industry. Recommended actions have also been successfully assessed through RE3IS. Future development of this research is to build a digital prototype of an internet of thongs-based decision support system platform that can be easily accessed by sunflower agro-industry managers. The stages in this research are still limited to the recommendation stage for corrective action. The implementation stage can be used as research development in the future. Apart from that, situational analysis is still limited to upstream and intermediate supply chain networks. Therefore, situational analysis of the downstream supply chain network can be carried out in the future.

MINIMALLY PROCESS ON CUT PEELED CHAYOTE

2024-09-05T14:40:47+07:00

Chayote is a vegetable that can be processed into various kinds of dishes. If you peel chayote, it will leave a sticky sap on your hands that is not easy to remove even if you wash it repeatedly with soap. Rumah Sayur Cisarua, Bandung Barat markets cut peeled chayote products. Cut peeled chayote quickly experiences a decline in quality, characterized by the color changing to brownish (enzymatic browning). For this reason, research was carried out with the aim of obtaining a minimally process design for cut peeled chayote. The treatment design tested was chemical treatment, by immersion in citric acid solution (0.5; 1.0; 1.5%) and sodium metabisulfite solution (500, 750, 1000 ppm), physical treatment by blanching (10, 20, 30 seconds ), as well as a combination of chemical and physical treatments. The minimally process design chosen was soaking in 500 ppm sodium metabisulfite for 15 minutes and sulfite residue was not detected. Cut peeled chayote with this treatment remains fresh until the fourth day of storage.

Keywords: minimally process, sodium metabisulfite, cut peeled chayote
