Abstract

The production of ethanol from molasses generates vinasse as a by-product of the distillation process. Vinasse waste produced by PT Energi Agro Nusantara contains COD and BOD levels of 910.5 ppm and 460.5 ppm, respectively, which significantly exceed the maximum limits set by wastewater quality standards, necessitating treatment. One treatment method is the use of Advanced Oxidation Processes (AOPs), which utilize hydroxyl radicals to oxidize organic pollutants in vinasse. One such process is the electro-Fenton process. In this study, 500 ml of vinasse was placed in a beaker and stirred for 90 minutes. A 25 ml addition of hydrogen peroxide was made, with a 2 cm gap between the iron electrode plates. Voltage variations of 3V, 6V, 9V, and 12V, along with electrode thicknesses of 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm, were tested. COD and BOD levels were analyzed using the titrimetric method. The results showed that increasing the voltage and electrode thickness reduced COD and BOD levels, while the percentages of COD and BOD removal increased. The highest voltage (12V) and electrode thickness (6 mm) yielded the lowest final COD and BOD values of 163.5 ppm and 88.9 ppm, respectively, with COD removal at 82% and BOD removal at 81%.

Abstract

Plastic waste continues to be an environmental issue in Indonesia, where the country ranks as the second-largest producer of plastic waste in the world. Bioplastics, derived from renewable materials such as starch, have the potential to serve as an alternative to conventional plastics. The objective of this research is to formulate biodegradable bioplastics utilizing sweet potato peel starch, carboxymethyl cellulose (CMC), and gum Arabic, with glycerol added as a plasticizer. Initially, extraction was performed to obtain starch from sweet potato peels. Subsequently, the bioplastic production process was carried out using the wet mixing followed by the casting method by mixing 5 grams of sweet potato starch with the CMC in various weights (0.1, 0.2, 0.3, 0.4, and 0.5 grams) and gum Arabic (1, 1.5, 2, 2.5, and 3 grams). Mechanical property tests were conducted to evaluate the quality of the bioplastics, including tensile strength, elongation, and apparent modulus. The results indicate that higher concentrations of CMC and gum Arabic enhance tensile strength and rigidity, with a maximum tensile strength of 1.51 MPa achieved. However, increasing CMC concentration can reduce elongation properties. The bioplastics exhibited water absorption ranging from 15.3% to 81.3%, while biodegradability tests demonstrated that samples reached degradation levels of up to 93.8% within 28 days. This study demonstrates that sweet potato peel starch, combined with CMC and gum Arabic, can produce bioplastics with favorable mechanical properties and environmental friendliness, thus presenting a potential alternative method for reducing plastic pollution in Indonesia.

Abstract

This research aims to examine the fermentation process in mushroom baglog waste and bat guano as ingredients for making multinutrient fertilizer, as well as to determine the fermentation time and composition ratio of the best raw materials with the highest and appropriate nutrient content according to the 2019 Ministry of Agriculture Regulation. The research was carried out in June - August 2023 located at the Graha Riset Universitas Pembangunan Nasional ‘Veteran’, East Java. Making multinutrient fertilizer from white oyster mushroom baglog waste and bat droppings is carried out using an anaerobic fermentation process with specified variables, namely: total mass of material: 10kg, volume of EM-4: 10ml, mass of sugar: 10 grams, and volume of water: 500ml. The research was carried out with variable fermentation times (days): 8, 12, 16, and 20 and composition ratios (baglog waste: bat droppings): (3:1), (2:1), (1:1), (1: 2), and (1:3). The results of the research show that the fermentation process helps decompose organic material as indicated by changes in levels of nitrogen, phosphate, potassium, and C/N. The decomposition of organic material in the fermentation process is indicated by physical changes that occur such as reduced water content due to the increase in temperature of the fertilizer during the fermentation process, changes in pH, as well as the blackish brown color of the fertilizer and a texture that resembles the texture of soil. The best fermentation time and ratio of raw material composition with the highest nutrient content was obtained on the 16th day of fermentation with a ratio of 3:1 with a Nitrogen content of 4.22%, Phosphate 3.14%, Potassium 4.25%, and C-Organic 27. 22%. Overall, the levels of Nitrogen, Phosphate, Potassium and C/N in the multinutrient fertilizer produced with variable time and composition in this study have met the 2019 Minister of Agriculture Regulation.

Abstract

This review systematically evaluates glycolysis-mediated depolymerization configurations to establish kinetic benchmarks for terephthalic acid (TPA) recovery, comparing conventional thermal heating against microwave-assisted routes utilizing Deep Eutectic Solvents (DES). Adhering to PRISMA guidelines, we analyze the operating parameters, degradation mechanisms, monomer yields, and carbon emission profiles to map the thermodynamic and mass transport boundaries of both pathways. The synthesized data reveals that microwave-assisted configurations achieve intense kinetic acceleration, enabling 100% polymer conversion within a highly compressed duration of 3.5 to 10 minutes by delivering uniform volumetric heating that bypasses traditional conductive resistance. Furthermore, integrating DES systems utilizing thiourea-based hydrogen bond donors optimizes charge density and coordination, pushing peak TPA yields up to 80.66%, which significantly outperforms conventional urea-based alternatives. However, from an environmental standpoint, the microwave-assisted system generates a higher carbon footprint of 0.364 tons of CO? per year compared to the 0.269 tons of CO? per year produced by simpler thermal techniques. While microwave-assisted DES glycolysis offers an expedited pathway for circular resource recovery, its practical industrial scale-up remains constrained by severe technical trade-offs, localized electrical arcing risks, thermal tracking lags, and elevated carbon loads.

Abstract

The community service program to assist the Small Micro Medium Enterprise in Tambakan Village, Blitar Regency East Java, has been done. The program's purpose was to improve the productivity of Taro chips as the prime product of Berkah Mulya Small Micro Medium Enterprise by introducing the appropriate technology to the taro chips making process. Currently, taro chips are produced manually. People did all the steps from cutting, frying, oil separating, and packaging by hand. It was time-consuming. The products sometimes were not uniform in thickness beside the oil content was relatively high, so the product was easy to be rancid. We introduced the cutting machine and the spinner to improve Taro Chips production's quality and quantity in this program. The methods used in this program started with a field survey, observation, socialization, the introduction of the appropriate technology (cutting and spinner machine), workshop and training, and evaluation. By applying the technology, the productivity increased from 5 kg/ day become 25 kg/day. The product's quality also becomes uniform in thickness, and the expiration date becomes longer

Abstract

Tomato is one agricultural commodity from Batu City which is soabundant in number. Although the number of products is relativelyhigh, the benefit earned by tomato farmers is still uncertain due to pricefluctuation. The other problem is the characteristic of the tomato thateasy to get rotten. This condition increases the risk of farmers to getloss. One alternative solution to minimize the risk is processing thetomato as a sweet-dried tomato. Conversely, The sweet dried tomatoproduct is still less popular than the fruit cracker in Batu City. Throughthe community service program, we help local people to makeStrengths, Weaknesses, Opportunities, and Threats (SWOT analysis) tosee the prospect of sweet-dried tomatoes. We also recommended somestrategies for developing the sweet-dried tomatoes business to thevillage authority.

Abstract

Indonesia merupakan negara agraris yang memiliki kebutuhan pupuk tinggi, namun produksi pupuk dalam negeri belum mampu memenuhi kebutuhan tersebut sehingga diperlukan alternatif pupuk organik. Penelitian ini bertujuan untuk mempelajari pengaruh waktu fermentasi dan perbandingan bahan terhadap kandungan unsur hara pupuk organik cair (POC) berbahan daun mangga dan pelepah pisang menggunakan bioaktivator Effective Microorganisms 4 (EM4). Proses fermentasi dilakukan secara anaerob dengan variasi perbandingan pelepah pisang (1:0, 1:1, 0:1) serta variasi waktu fermentasi (8, 12, 16 hari). Parameter yang dianalisis meliputi kadar C-Organik, Nitrogen (N), Fosfat (P₂O₅), Kalium (K₂O), dan rasio C/N menggunakan metode spektrofotometri, Kjeldahl, dan AAS. Hasil penelitian menunjukkan bahwa kondisi optimum diperoleh pada hari ke-12 dengan perbandingan bahan 0:1 (pelepah pisang : daun mangga), menghasilkan kadar C-Organik sebesar 13,718%, Nitrogen sebesar 1,247%, Fosfat sebesar 1,739%, Kalium sebesar 2,511%, dan rasio C/N sebesar 11,0008. Perlakuan tersebut telah memenuhi standar mutu pupuk organik cair berdasarkan Peraturan Menteri Pertanian (PERMENTAN) 2011. Penggunaan daun mangga dalam proporsi lebih tinggi terbukti menghasilkan kandungan unsur hara makro yang lebih tinggi dibandingkan pelepah pisang, karena daun mangga memiliki kandungan nitrogen dan mineral yang lebih tinggi serta struktur jaringan yang lebih mudah terdekomposisi.
