Abstract

Plastic is the dominant packaging used by the public, so it has the potential to damage the environment. It is necessary to synthesize raw materials for making plastics that are degraded by microorganisms, namely bioplastics. Bioplastics are packaging materials that are synthesized from natural raw materials so that they can be degraded in the environment. The raw material used is corncob because it is abundant and the benefits are not maximized. Research is needed to examine the stages of the production process and the characterization of bioplastics from corncob waste. The purpose of this study was to examine the stages of the production process and the characterization of bioplastics from corncob waste. This study used a laboratory experimental method with descriptive analysis. The production of bioplastics consists of the stages of making cellulose, cellulose acetate, and bioplastics using the solution casting method. The stages of cellulose isolation include hydrolysis, delignification, pulping, and bleaching, which showed an increase in cellulose content from 32.14% to 79.36%. Cellulose is acetylated to become cellulose acetate and has an acetyl content of 11.70 ± 0.40% with a yield of 121.16 ± 0.98%. The production of bioplastics uses a composition of cellulose acetate and chitosan at 50%:50% (w/w) successively. The resulting bioplastic has a thickness of 0.345 ± 0.024 mm, a density of 0.83 ± 0.03 g/cm3, a moisture content of 13.13%, a biodegradation value of 95.19%, a water resistance of 205.57%, and is transparent. The mechanical properties of bioplastics include a tensile strength of 22.3 N/m, an elongation of 21.11%, and a modulus of elasticity of 0.307 Mpa.

Abstract

Oil Palm Empty Fruit Bunch (OPEFB) is a type of solid waste from the palm oil processing industry. The components of OPEFB include cellulose, hemicellulose, and lignin. OPEFB has a large cellulose content, so it possesses the potential to be used as a bioplastic material. The purpose of this research was to examine the stages of the bioplastics' production process and its characterization. The cellulose content of OPEFB as raw material and during the isolation process which includes hydrolysis, delignification, pulping, and bleaching are 39.59%, 56.00%, 59.85%, 61.48%, and 68.20%, respectively. Cellulose isolation produces α-cellulose content of 97.87%. The resulting cellulose acetate has an acetyl content of 25.93%. The bioplastics were then characterized to determine the effect of cellulose acetate, starch, chitosan, and glycerol on the physical and mechanical properties of the plastics. The results of the physical properties characterization include biodegradability, water absorption, and density with values of 78.73%, 38.26%, and 1.2% respectively. The results of the mechanical properties characterization include tensile strength, elongation, and modulus of elasticity with values of 0.729 MPa, 4.13%, and 17.5 MPa, respectively. The functional groups in the bioplastics, which are O-H, C-H, C-O, C=O, and N-H, are produced from the mixing process between cellulose acetate, starch, chitosan, and glycerol.

Abstract

As the demand for efficient and cost-effective greenhouse microclimate surveillance has increased, we developed a microclimate surveillance system using microcontroller technology that automatically collects temperature and relative humidity data and transmits it to a cloud server for remote surveillance and data analysis. 1971 microclimate data points were acquired over a 20-day evaluation period, providing insights into greenhouse environmental conditions with a negative linear regression between air temperature and relative humidity within the greenhouse and an R-squared of 0.73. This illustrates the system’s ability to record and quantify environmental conditions data. Additionally, we derived a predictive model to manage microclimate conditions using the regression formula y = -6.12X + 238.33, where X represents the air temperature and y represents the relative humidity. All the results show that the acquired data can be used to make decisions to optimize plant growth. The prototype we developed can be an alternative option for small and medium-sized farms that need a greenhouse surveillance system to improve operational efficiency and reduce surveillance costs. The system can be further developed by implementing additional sensors to monitor light intensity, wind speed, or soil moisture and further data analysis models to optimize greenhouse management.

Abstract

Salted eggs are a popular product, but their fragile nature requires preservation methods. One such method is salting. The production process involves direct costs (raw materials and labor) and indirect costs. Minimizing production costs is crucial for maximizing profit and shaping the company's strategy.This study aims to compares the method of curing salted eggs using red bricks and ash with salting eggs using reverse osmosis technology. Reverse osmosis method is an innovative approach in salted egg production that replaces the traditional salting method. In this method, eggs are not soaked in a salt solution but processed using high-pressure equipment to remove water from the eggs and introduce salt into them. This allows for a reduction in the time required for the salted egg production process. The result showed that the Total cost of production per one product cycle with the reverse osmosis method has a lower cost than conventional methods of IDR.257.88. The red brick method has a total cost of IDR.993,401, and the method of ash rub was the highest, with a total cost of IDR.1.017.701.Therefore, the reverse osmosis method becomes the best salting method in a cost-efficient way and has better performance.

Abstract

Bananas are a popular fruit in Indonesia, where banana plantations can be found from Aceh to Papua, with a total harvest of 105.801 tons in 2019. Kampung Cau Padjadjaran (UKM KCP), with partner farmers in various regions, is one of the SMEs that manage banana farmers in West Java. The issue is that banana purchases and sales between KCP SMEs, consumers, and farmers are still done manually, resulting in a longer transaction process. Based on this, an Android-based application was created to manage KCP SMEs' buy and sell transactions. Customers can use their smartphones to check banana stocks and process transactions by installing this app. The app is built with the Object-Oriented Programming (OOP) method and the Android Studio framework, as well as a Firebase database that uses cloud technology. This application is called MyBanana, and it has several features that assist consumers, farmers, and KCP SMEs in managing data, information, and transactions, such as the Sign-Up and Login process, which provides security for users to make transactions, and the Banana Type List, which informs the type of banana consumed. The availability of banana stocks is updated in real-time by UKM KCP, and the buying and selling transaction process is simple. The black box test results show that the built application has the features expected by KCP SMEs and functions properly.

Abstract

The cultivation of maggots through the larvae of black soldier fly (Hemetia illucens) is increasingly recognized as a viable solution for organic waste management and alternative protein production. However, its integration into village-based enterprises and implications for Micro, Small and Medium Enterprises (MSMEs) competitiveness remain underexplored. This study examines how maggot cultivation strengthens food MSMEs using a circular economy framework and SWOT (strengths, weaknesses, opportunities, and threats) analysis. The study was conducted at Village-Owned Enterprises (Badan Usaha Milik Desa and abbreviated by BUMDes in Bahasa Indonesia) Kerta Setra Utama in Tasikmalaya, Indonesia. A mixed-methods approach was applied, combining qualitative observation with quantitative analyses of waste reduction, maggot yield, and protein content. Results showed a 65% reduction in organic waste within 5 days, a 28% increase in maggot biomass across 6 production cycles, and a 30% increase in household incomes. Using poultry manure as a substrate reduced waste by 31.2%. Furthermore, the substrate resulted in 114 g of dry weight.kg-1 of feed as well as 25.26% crude protein in less than eight days. SWOT analysis identified key constraints in community participation, institutional support, and technological capacity. There were opportunities that came from the integration of the circular economy and the expansion of green markets. The findings demonstrate that rural enterprises can effectively transform organic waste into economic value through maggot farming. Policy recommendations emphasize capacity building, green financing, and digital market integration to enhance scalability and long-term impact.
