Abstract

Indonesia adalah negara agraris yang memiliki hasil pertanian melimpah, salah satunya bayam. Akan tetapi, petani bayam masih diikuti oleh banyak kendala seperti teknis budidaya, hama dan penyakit, pupuk hingga pemasaran hasil panen yang masih tradisional. Disisi lain, potensi limbah jerami padi yang melimpah memiliki unsur hara penting yang dibutuhkan oleh tanaman, seperti Si (Silika), K2O (Kalium Oksida), P2O5 (Potassium Pentaoksida dan N (Nitrogen). Unsur-unsur tersebut akan hilang apabila dilakukan pembakaran. Oleh karena itu, penelitian ini ditujukan untuk ekstraksi unsur hara limbah jerami padi dan memanfaatkannya sebagai sumber N, P, dan K organik dalam pembuatan pupuk cair. Penelitian ini memberikan hasil bahwa semakin lama waktu ekstraksi, dapat menghasilkan unsur hara yang lebih tinggi sehingga berpengaruh positif terhadap pertumbuhan tanaman bayam. Selain itu, pupuk organik cair komersial secara kimia memiliki kandungan nitrogen tinggi. Namun, pupuk cair dari limbah jerami juga memiliki potensi yang besar sebagai pupuk organik karena memiliki kandungan fosfor dan kalsium yang tinggi.

Abstract

Soybeans (Glycine max) are a type of legume with moderately high fat content. Appropriate and safe types of solvents are essential in extracting fatty acids for consumption. This study aims to find an alternative solvent to replace n-hexane for extracting soybean oil and analyze its lab-scale production cost. Soybean oil was extracted by soxhlet extraction using ethanol, ethyl acetate, and n-hexane with a soybean-to-solvent ratio of 1:4 and 2:4 (w/v) and an extraction time of 1 and 2 hours. The results show that solvent polarity and soybean: solvent ratio affect the yield and density of the resulting extract. The greater the soybean-to-solvent ratio, the more oil is extracted until equilibrium. The highest yield was 36.25%, obtained at a material-to-solvent ratio of 2:4 (w/v) within 2 hours with ethyl acetate, and the oil density was 0.92 g/mL. The Gas Chromatography-Mass Spectrophotometry (GC-MS) analysis on the sample with the highest yield showed that the fatty acid composition was 34.36% linoleic acid, 22.12% palmitic acid, 19.40% stearic acid and 19.43% octadecadienoic acid. Ethyl acetate produces better yields and can be recommended as an alternative solvent to replace n-hexane for soybean oil extraction. The total extract production costs for 70% ethanol, 90% ethyl acetate, and 95% n-hexane solvents are IDR 780,847; 647,232; and 692,050, respectively.

Abstract

Laboratory is one of the generators of hazardous liquid waste derived from chemicals used in practice and research. The waste is very dangerous when discharged into the environment because of the pollutants it contains. Therefore, it is necessary to treat the waste before it is disposed of to minimize the impact of pollution caused by the waste. The study aims to compare the effectiveness of zeolite adsorbents and activated carbon in reducing COD, TSS, and Cr heavy metals. Waste treatment is carried out by coagulation and adsorption methods. The adsorption process is performed using two types of adsorbents: zeolite and activated carbon. This study was carried out by variing the mass of the adsorbents at the time of complaining for 120 minutes in batches. Variations in the masses of the used 3, 5, 7, and 10 grams of adsorbenes. The results of the study showed that the more adsorbanes used, the higher the reduction of pollutant levels. The use of 10 grams of activated carbon adsorbents can reduce TSS pollutants levels of 92%, COD 95%, Cr 65%, and pH 5,0-6,38.

Abstract

Papaya leaves (Carica papaya Linn) have many health benefits, such as antibacterial, anti-inflammatory, antidiarrhea, and others. Papaya leaves contain tannins, saponins, alkaloids, triterpenoids, steroids, and flavonoids. The common characteristic of papaya leaves is the green color, which indicates the presence of tannins. The study aims to discover the characteristics of papaya leaf extract, the effect of the solvent ratio, and the microwave power (MP) on the extraction of tannins from the papaya leaves. Papaya leaves are extracted using the microwave-assisted extraction (MAE) method at 100, 140, and 180 W for 30 minutes, with variations in the material to the solvent ratios 1:10, 1:20, 1:30, 1:40, and 1:50. Qualitative tannin testing was carried out through color observation and FeCl3 tests. UV-Vis spectrophotometry was also used to determine the tannin levels obtained during extraction. The FeCl3 test showed that papaya leaf extract contains tannins. The optimal concentration of tannins is produced at a ratio of 1:20, with a 180 W MP of 8.06 mg TAE/g and a yield of 0.81%. MAE can potentially increase the yield of tannins, which is potentially beneficial to health.

Abstract

Paper waste is one type of waste that is quite abundant. Effective processing of paper waste can be done using hydrolysis process because this process can decompose lignocellulose compounds in paper waste into simpler compound such as glucose and other derivative products. Hydrolysis process was generally carried out using chemical catalysts such as acids, bases and enzymes. In this study, paper waste hydrolysis was investigated using base catalysts such as potassium hydroxide (KOH) from palm oil empty fruit bunches (POEFB) ash and commercial KOH. The research stages began with the preparation of POEFB ash, KOH production from POEFB ash, paper waste preparation, and the hydrolysis process of paper waste using KOH from POEFB ash and commercial KOH. This study uses variations in hydrolysis time were carried out to evaluate the hydrolysis conversion. Based on the research, it was showed that KOH catalyst from POEFB ash contain potassium compounds in the form of 5.87% potassium oxide (K2O) and 31.45% potassium carbonate (K2CO3). Comparison of catalyst performance between KOH catalyst from POEFB ash and commercial KOH catalyst showed that commercial KOH catalyst was better than KOH catalyst from POEFB ash. The effect of hydrolysis reaction time was directly proportional to the conversion value that the highest conversion was 12.11% at 90 minutes using commercial KOH catalyst.

Abstract

Dalam upaya mengurangi ketergantungan terhadap energi fosil, sel surya menjadi salah satu potensi energi terbarukan yang menjanjikan, terutama di wilayah dengan intensitas cahaya matahari yang tinggi seperti di Indonesia. Berbagai jenis sel surya telah banyak dikembangkan, mulai dari generasi pertama hingga generasi ketiga sebagai era baru dalam perkembangan teknologi sel surya. Concentrated Solar Cell (CSC) memunculkan harapan baru dalam pemanfaatan energi surya. Konsep dasar CSC melibatkan penggunaan lensa atau cermin konsentrator untuk meningkatkan intensitas cahaya matahari yang mencapai sel surya. Dengan memanfaatkan efek fotovoltaik pada material semikonduktor, CSC dapat meningkatkan efisiensi konversi energi matahari menjadi listrik. Mekanisme kerja CSC tidak hanya mengurangi jumlah sel yang diperlukan, tetapi juga memungkinkan desain multi-junction tandem yang lebih efisien, menggunakan bahan dan proses produksi yang umumnya mahal namun menjadi lebih terjangkau melalui penggunaan CSC. Berdasarkan ulasan analisis siklus hidup (LCA) yang dilakukan beberapa peneliti, CSC menunjukkan keunggulan dalam pengurangan material terbatas, seperti germanium (Ge) dan gallium (Ga), yang mendukung keberlanjutan pada skala besar. Keunggulan ini memberikan gambaran lebih luas tentang dampak positif CSC terhadap penurunan ketergantungan pada sumber daya yang langka dan peningkatan keberlanjutan di sektor energi.

Essential oil craftsmen at the Al-Fattah Islamic Boarding School Cooperative (KOPPONTREN), Negara Ratu Village, Natar District, South Lampung Regency, who are our service partners, have been processing eucalyptus oil through simple distillation. However, the produced yield is only around 0.6–0.7%. Additionally, the generation of processing waste, the low selling price due to poor quality, and the lack of product marketing are the reasons behind this Community Service (PkM) activity. This activity improved the quality of eucalyptus oil products by creating a redistillation device. Socialization of solid and liquid waste treatment in the SSF Constructed Wetland reactor with wlingi grass plants was also conducted. In addition, digital marketing training and packaging design creation were conducted as a complement to this PkM activity. Overall, the training results show that 86% of participants experienced a significant improvement in their abilities, with an average post-test score of 83.8. This result is quite encouraging, meaning that the implementation of socialization activities and practices of eucalyptus oil distillation, liquid and solid waste processing, as well as product branding, can be well followed by partners. Keywords: Product Branding, Eucalyptus Oil, Waste Processing, Redistillation.

Abstract

Biodiesel is a potential renewable energy that can reduce greenhouse gas (GHG) emissions and increase energy security. Biodiesel has been shown to have lower carbon emissions compared to petroleum diesel, and it can reduce GHG by as much as 86%. Governments around the world have set targets for renewable energy, with a specific focus on the use of biofuels like biodiesel. Biodiesel can be derived from various feedstocks such as animal lipids, vegetable oils, and waste oils. It can be made through the transesterification of triglyceride with ethanol or methanol. This reaction requires strong base catalysts, such as sodium hydroxide or potassium hydroxide, in order to produce methyl esters. The potential of biodiesel has led to advancements in its production, such as the use of enzymatic transesterification, novel feedstocks, and the optimization of production parameters. Additionally, various companies have ventured into biodiesel production with a range of business models and approaches.
