Abstract

Bioetanol merupakan bahan bakar nabati yang dapat dijadikan sebagai alternatif untuk menggantikan bahan bakar fosil yang tidak dapat diperbarui. Sementara buah nanas yang biasa dikonsumsi hanya diambil buahnya saja, sedangkan bagian kulit nya hanya dijadikan limbah buah yang dibuang begitu saja, padahal dalam kulit nanas memiliki kandungan gula dan karbohidrat yang cukup tinggi, sehingga berpotensi untuk dimanfaatkan sebagai bahan baku pembuatan bioetanol.  Tujuan dari penelitian agar dapat memanfaatkan limbah kulit nanas untuk dijadikan bahan baku pembuatan bioetanol serta mengetahui kadar bioetanol yang dihasilkan. Adapun metode yang digunakan yaitu fermentasi menggunakan Saccharomyces Cerevisiae terimobilisasi dalam butiran alginate. Kulit nanas di buat serbuk yang selanjutnya dihidrolisis menggunakan asam klorida dengan variasi konsentrasi 1M, 2M, dan 3M. Larutan gula yang dihasilkan dari proses hidrolisis kemudian diukur kadar gulanya menggunakan refraktometer gula setelah itu difermentasi oleh Saccharomyces Cerevisiae terimobilisasi dalam butiran alginate selama 4 hari. Alkohol yang terbentuk diukur kadar alkoholnya menggunakan refraktometer alkohol, kemudian butiran alginate yang digunakan diukur diameternya menggunakan jangka sorong. Pada proses hidrolisis, konsentrasi asam mempengaruhi perolehan konsentrasi gula. Konsentrasi gula terbesar dihasilkan yaitu dengan menggunakan HCl 3 M dimana konsentasi yang dihasilkan 21OBrix. Konsentrasi alkohol tertinggi yang dihasilkan sebesar 55% volume oleh yeast terimobilisasi dalam butiran alginate dengan diameter 2,86 mm.

Abstract

Cilokolot Village, RT 02 RW 02, Margahayu Selatan, Bandung Regency, is a densely populated area where traditional tempeh production occurs. In this village, there are two small-scale tempeh factories involving seven artisans, processing approximately 700 kg of soybeans daily. This study focuses on one factory, which is smaller and utilizes traditional technology, with a production capacity of 200 kg per day and firewood as its fuel source. The tempeh production process consists of boiling, soaking, separating, washing soybeans, fermenting, and packaging, which generates significant volumes of liquid waste. One of the tempeh artisans also has a livestock farm with ten cattle, fifteen goats, and a few turkeys, ducks, and chickens. Waste from tempeh and animal manure is often discharged directly into rivers and vacant land, leading to air, soil, and water pollution, which poses health risks. Biogas energy is produced through microbial processing of organic waste, such as vegetable scraps, fruit peels, leftover rice, livestock manure, and tempeh waste. The main components of biogas are methane and carbon dioxide. The objectives of this study are: 1) to educate artisans on the negative impacts of tempeh waste and livestock manure on the environment; 2) to install a Wastewater Treatment Plant (WWTP) for managing tempeh waste and cattle manure; 3) to provide training and support for processing tempeh waste and animal manure into biogas and Liquid Organic Fertilizer (LOF); and 4) to conduct training on the application of LOF to crops. The methods employed include outreach, training, technology implementation, ongoing support, and evaluation. The results indicate that: 1) artisans actively participated in socialization sessions addressing the negative impacts of tempeh waste and livestock manure; 2) the WWTP for tempeh waste and cattle manure has been successfully installed on land provided by the artisans; 3) training and support for operating the WWTP resulted in the successful production of biogas and LOF, which provide added value and benefits; and 4) training on the application of LOF to demonstration plots has been conducted, with enthusiastic participation from the artisans.

Abstract

The tempeh industry uses soybeans as the main raw material to produce the main product, namely tempeh. Based on observations of the local industry, tempeh production waste in the South Margahayu area is very high, because more than one factory produces tempeh waste. Utilization of waste materials as organic fertilizer is one way to overcome environmental pollution problems. Banana peels contain many substances and are beneficial for plants if processed into liquid organic fertilizer, because banana peels contain 42% potassium so that they can strengthen plant stems, fight diseases, and fertilize plants and flowers and fruit trees. This study uses 1 type of stage, namely the liquid organic fertilizer production process. Testing of liquid organic fertilizers made from liquid tempeh waste and banana peels was carried out to determine the suitability between the levels of macro nutrients produced from the liquid organic fertilizer with the standard quality of liquid organic fertilizers based on SNI. The analysis method in this study uses a quantitative method obtained from the results of measuring the levels of nutrients in raw materials and liquid organic fertilizers. The protein content in the results of the tempeh liquid waste test was 0.48%. The C-Organic content on the 7th day was 1.72%. On the 7th day, the nitrogen produced was 0.10%, phosphorus was 0.07%, and potassium was 0.62%. Based on the results of the study, the optimum fermentation time for the production of organic liquid fertilizers was on the 7th day with a total NPK content of 0.79%, C/N of 20 and C-organic 1.72%. The production of POC from tempeh liquid waste with the addition of banana peels has not produced macronutrient levels that are in accordance with the SNI standards for organic liquid fertilizers so that commercial production cannot be carried out. Many factors influence the process of forming this liquid organic fertilizer, including bioactivators, namely effective microorganisms commonly known as EM-4, temperature, sun intensity, humidity, production time and placement in the fertilizer production process.

Abstract

Detergents are the most polluting household waste because contain sulfonic surfactants, which are unbiodegradable, so there is a need to innovate environmentally friendly cleaning products. Household waste has become a serious global problem. However, the environmental impact of household waste is in the form of detergent waste, where the use of detergent sometimes exceeds the dosage and causes much more foam. Lerak fruit is a natural ingredient used as a raw material for the detergent. This community service aims to educate people on making environmentally friendly detergent which was held at the Sumedang Logistics Vocational School. This PKM activity was carried out by outreach to 25 teacher and student representatives. The main objective of this community service activity is to provide knowledge and training on environmentally friendly Lerak detergent to encourage the entrepreneurial spirit and skills of teachers and students of the Sumedang Logistics Vocational School. This activity is a real contribution to utilizing natural resources while maintaining environmental health. The detergent manufacturing process involves saponin extraction using a hot water extraction method, followed by formulation using additional ingredients such as organic fragrances.

Abstract

Green tea is a plant that has polyphenolic active compounds. Polyphenols are a group of compounds that act as natural antioxidants. Antioxidants are needed by the body to protect the body from free radical attacks. The polyphenol content in the tea leaves itself is influenced by the weather, variety, soil type, and the degree of maturity of the leaves when picked. Therefore, in this study green tea shoots were used because the polyphenol content and antioxidant activity of green tea in the shoots are known to be greater than the leaves on the stalks below. This study aims to determine the levels of polyphenols in green tea shoots using distilled water, 50% ethanol; 96% ethanol and determine the value of antioxidant activity obtained from the results of samples that have the highest levels of total polyphenols by maceration method for 24 hours. The results of maceration are then separated between the filtrate and the precipitate. Then the filtrate is concentrated to obtain a thick extract and removes the remaining solvent using a rotary evaporator that is set to a pressure of 1 bar and a temperature below the boiling point of the solvent. Furthermore, the viscous extract obtained was tested by the Follin-Ciocalteu method using UV-Vis spectrophotometry at a wavelength of 765 nm and gallic acid as a standard to determine the levels of polyphenolic compounds. The test results for the highest levels of polyphenols were tested for antioxidant activity using the DPPH method (2,2 Diphenyl -1-Pikrylhidrazyl) which causes a color change and then measured using a spectrophotometer at a wavelength of 512 nm. Antioxidant activity can be seen from the IC50 (inhibitory concentration) value or the concentration that can reduce 50% of free radicals because the lower the IC50 value, the greater the antioxidant activity. The results showed that the levels of polyphenols in green tea shoot extract were respectively 16.47%; 22.16%; 18.09% so that the highest levels of polyphenols were obtained in green tea leaf extract macerated using 50% ethanol solvent. The results of the antioxidant activity test on samples using 50% ethanol solvent obtained an IC50 value of 5.7 ppm and included in the very good category.
