Abstract

Soybean is a commodity that has an important role in industrial development, especially in the tofu, tempeh, and soy sauce industries. Waste from soybean hulls is still not widely utilized, only used for feed and beverages for cattle. Similarly, durian peels are only utilized for the fruit's meat and seeds, and the peels are thrown away. Product innovation based on durian peels and soybean hulls needs to be implemented to optimize the utilization of these two wastes to increase economic value. The high cellulose content of both wastes can be utilized as raw material for biobriquettes as an alternative to fossil fuelsusing a carbonization process in a chamber furnace at a temperature of 200-250 °C. The higher the ratio of soybean hulls and durian peels produces a high heating value followed by a decrease in moisture content and ash content. The results showed that the biobriquettes from soybean hulls and durian peels have complied with SNI 01-6235-2000. The best condition is obtained by the composition ratio of soybean hulls and durian peels 25:75 (%w/w) with 4 grams of adhesive which produces a calorific value of 5444 cal/g, a moisture content of 4.9%, and an ash content of 6.89%.

Abstract

Corona virus Disease-2019 (COVID-19) merupakan penyakit menular yang disebabkan oleh virus bernama SARS – COV-2 atau yang dikenal dengan VIRUS CORONA. Virus Corona ini menyebabkan infeksi saluran nafas pada manusia mulai dari batuk pilek hingga yang lebih serius seperti Middle East Respiratory Syndrome (MERS) dan Severe Acute Respiratory Syndrome (SARS). Penyebaran virus COVID- 19 meningkat semakin cepat melalui tetesan air liur atau keluar dari hidung ketika orang yang terinfeksi batuk atau bersin. Namun demikian, masih sedikit pemahaman dan kesadaran masyarakat di Desa Malangsari, Kecamatan Tanjung Anom, Kabupaten Nganjuk yang mematuhi protokol kesehatan saat beraktivitas di luar rumah. Oleh karena itu, perlunya peningkatan pemahaman COVID-19 dan pentingnya mematuhi protokol kesehatan dalam upaya pencegahan dan pemutusan mata rantai penularan COVID-19. Kegiatan yang dilakukan dengan metode Edukasi COVID-19 kepada Masyarakat desa Malangsari melalui sosialisasi, penempelan pamflet di tempat umum, penerapan protokol kesehatan, dan media sosial. Dengan demikian, harapan Desa Malangsari terbebas dari virus corona dapat terwujud.

Abstract

Water hyacinth is a freshwater plant that has a negative impact on waters, but has a high cellulose content (77.6%) and is still underutilized. One alternative in controlling the amount of water hyacinth is to utilize its potential cellulose content as an ingredient in xanthan gum. Fermentation was carried out with the help of Xanthomonas campestris and xanthan gum was obtained, which can be used as a polymer injection material to increase crude oil production in the oil refinery industry. The stages to obtain xanthan gum are delignification, hydrolysis, and anaerobic fermentation (28 °C) with a time variation of 24 hours to 120 hours with an interval of 24 hours. The cellulose hydrolysate variable is 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The yield of xanthan gum in this research was 18%, with a moisture content was 13% – 15% and an ash content was 3% –3.9%. The resulting xanthan gum was analyzed for its functional groups using Fourier Transform Infra Red (FTIR) and was in agreement with commercial xathan gum.

Abstract

Precipitated calcium carbonate (PCC) with a size of less than 100 nm has been shown to improve the hardness and strength of a material, making it suitable as a filler in the production of bioplastics. Biodegradable plastics are plastics that can be used like conventional plastics, but can be broken down by microorganisms after use, making them environmentally friendly. The aim of this study is to investigate the effect of adding nanoprecipitated calcium carbonate (PCC) filler and glycerol on the mechanical properties and biodegradation of corn starch-based bioplastics, and to produce biodegradable plastic that meets the Indonesian National Standard (SNI). The method used is melt intercalation to produce bioplastics from corn starch with the addition of nano-PCC and glycerol. The best results were obtained with 12% Nano-PCC and 20% glycerol, which gave a tensile strength of 3.54 MPa, 12% Nano-PCC and 50% glycerol, which gave an elongation percentage of 23.7%, and 4% Nano-PCC and 60% glycerol, which gave 100% biodegradation within 30 days. A higher concentration of Nano-PCC filler increases the tensile strength, improves the elongation percentage and reduces the degradation rate of the plastic. A higher concentration of glycerol decreases tensile strength, increases elongation and increases the degradation rate of the plastic.

Abstract

Agricultural waste from banana petioles and midribs represents an underutilized lignocellulosic biomass, particularly in Bojonegoro Regency, East Java. This study aims to optimize the cellulose hydrolysis process from this waste into glucose using sulfuric acid as a catalyst via the Response Surface Methodology (RSM). This study used the most abundant banana variety in the area, the Kepok banana. The variables tested included temperature (70–110°C) and reaction time (20–100 minutes). The glucose content of the hydrolysis product was measured using a sugar refractometer. The glucose content data were then converted to per cent cellulose conversion, which served as the basis for the optimization process. The results showed that temperature and time significantly influenced glucose conversion, with optimal conditions at 110°C for 100 minutes. The optimization model demonstrated a good fit, with an R² value exceeding 0.95. This research confirms the potential of utilizing local banana petiole and midrib waste as a glucose source, providing a scientific basis for sustainable, large-scale production.

Abstract

Activated carbon is an adsorbent commonly used in adsorption methods for waste treatment due to its high adsorption capacity and simple preparation. Nevertheless, activated carbon also has limitations, such as low adsorption efficiency, which necessitates the use of supporting materials to resolve these weaknesses. TiO₂ a semiconductor material used in photocatalysis for waste treatment, has the advantage of reducing contaminants through decomposition processes. Nevertheless, TiO₂ also has disadvantages, such as a low adsorption capacity and a tendency to agglomerate. To resolve the limitations of both activated carbon and TiO₂, a method of combining these materials is employed. The addition of TiO₂ to activated carbon through sonication disperses TiO₂ particles on the surface of the activated carbon particles, filling the pores inside the activated carbon structure and creating additional micro and mesopores. This process enhances the porosity and surface area of the activated carbon. This study is intended to determine the effect of TiO₂  addition ratio and HCl activator concentration on the quality of the activated carbon. The research methodology involves activating the carbon with HCl and addition of  TiO₂  in specific ratios through sonication. The best results were obtained with a treatment using 1 M HCl concentration and  5% TiO₂ addition ratio, which resulted in activated carbon with a surface area of 4257 m²/g. The addition of TiO₂ to HCl-activated carbon significantly increases the surface area compared to activated carbon without TiO₂.
