Abstract

Minyak goreng adalah minyak nabati yang dimana memiliki masa penggunaan yang terbatas dalam pemakaiannya.Oleh karena itu, minyak goreng yang melewati masa pengunaannya harus digantikan dengan minyak goreng yang baru. Minyak goreng yang tidak bisa dipakai inilah yang biasa disebut dengan minyak jelantah. Salah satu bentuk pemanfaatan minyak jelantah dengan cara mengolahnya kembali untuk pembuatan sabun padat. Sabun padat dihasilkan dari proses saponifikasi, yaitu hidrolisis lemak menjadi asam lemak dan gliserol. Tujuan dari pengabdian masyarakat ini yaitu untuk mengembangkan pengetahuan siswa siswi SMP Roudlotul Ulum Bangil, Pasuruan mengenai Technopreneurship. Technopreneurship itu sendiri yaitu penggabunga teknolgi dalam pembentukan sebuah usaha atau kewirausahaan. Salah satunya yaitu dengan mengolah limbah yang menjadi bahan yang terbuang yang banyak orang tidak mengetahui bahwa bila ddiproses dengan baik akan menghasilkan produk dengan nilai ekonomi yang tinggi. Metode yang kami gunakan yaitu pengumpulan minyak jelantah, pembutan sabun dari minyak jelantah,tahap analisa dan tahap pengenalan produk.

Abstract

Indonesia is a tropical country located on the equator with high sun exposure, so sunscreen is needed to reduce the risk of exposure to ultraviolet (UV) light. In this research, a sunscreen was developed that uses natural active ingredients in the form of lignin made from coconut coir. The aim of this research is to determine the comparison between the mass of coconut coir and the volume of ethanol solution that produces the highest lignin content, as well as the concentration comparison between lignin nanoparticles and commercial sunscreen that produces the highest SPF value. The synthesis of lignin from coconut coir was carried out using an extraction method using ethanol solvent, followed by a hydrolysis process with NaOH and acidification with H2SO4, while lignin nanoparticles were made using a pH shifting method using ammonia and HCl. The lignin nanoparticles formed are then added to the sunscreen's active ingredient. The variables used were the ratio of the mass of coconut coir to the volume of 80% ethanol solvent (1:5, 1:10, 1:15, and 1:20 (w-v)) and the concentration of lignin in commercial sunscreen cream (2%, 4%, 6%, 8%, and 10% (w-w)). The results of the research show that the higher the solvent ratio, the more lignin is produced, but will decrease after reaching the optimum point. The optimal solvent volume occurs at a ratio of 1:15 (w-v) with a yield of 12.94% (w-w). In addition, the higher the lignin concentration, the resulting SPF value will also increase. The best concentration is 10% (w-w) at a solvent ratio of 1:15 (w-v) with an SPF value of 22.23.

Abstract

Adsorption of Tofu Liquid Waste Using Rice Husk Activated Carbon. Rice husk is an agricultural by-product rich in organic matter, and improper management can cause environmental pollution. Given the high carbon content in rice husk, it can be used as an adsorbent. Furthermore, the type of activator and activation technique employed impact the properties of activated carbon. Due to its ability to produce activated carbon with a high pore volume and specific surface area, KOH is a chemical substance that is frequently employed. This study sought to ascertain whether rice husks might be used as activated carbon to lower the amount of organic matter in liquid effluent from the tofu business. The results of this study indicate that rice husk activated carbon can reduce the level of TDS by 27%, TSS by 97%, and pH 6 from the initial level. The optimum contact time is 120 minutes at a ratio variation of 1:130, because at that time the activated carbon has approached saturation by the adsorbed adsorbate and experienced equilibrium and saturation.

Abstract

Comparative Efficiency of KOH-Activated Rice Husk Carbon in Adsorbing Pollutants from Laundry and Tofu Wastewater. This study aims to compare the adsorption capacity of rice husk-based activated carbon in overcoming pollution from two types of liquid waste, namely laundry waste and tofu liquid waste. The raw material of rice husk is processed through a carbonization process and chemical activation using potassium hydroxide (KOH), then used in a batch adsorption test. The parameters analyzed include Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS). The results show that the adsorbent material produced is able to reduce pollutant levels significantly. COD and TDS are more effectively reduced in laundry waste because the organic content and surfactants are more easily adsorbed, while TSS experiences a greater decrease in tofu waste due to the high suspended solids content. The adsorption process follows the Langmuir isotherm model with the regression values for both laundry and tofu wastewater of  R2>0.9, which indicates the occurrence of monolayer adsorption on the surface. This biosorbent has proven to be economical, environmentally friendly, and has the potential to be applied on a small scale, especially for household industries such as laundry businesses and tofu production. In addition to being relevant for local contexts, this approach can also be adopted globally in areas with high rice husk availability and similar waste management problems.

Abstract

The utilization of agro-industrial waste as a feedstock for fuel-grade bioethanol offers a strategic opportunity to reduce dependence on fossil fuels and support the transition toward renewable energy. This study provides a systematic review of the potential of various Indonesian agro-industrial wastes, including lignocellulosic and non-lignocellulosic materials, along with the variation in ethanol yields produced through pretreatment, hydrolysis, fermentation, and purification processes. The analysis shows that feedstock characteristics, pretreatment efficiency, and microbial fermentation performance are key determinants of ethanol yield. A major challenge lies in the purification stage, as ethanol obtained from conventional distillation does not meet the fuel-grade requirement of ≥99.5% v/v. Several dehydration technologies—such as azeotropic distillation, extractive distillation, molecular sieves, membrane pervaporation, and PSA—can achieve high purity with distinct operational advantages. This review highlights the importance of integrating suitable purification methods and optimizing the conversion process to produce fuel-grade bioethanol that is technically and economically feasible. Overall, agro-industrial waste demonstrates significant potential to support national energy security and sustainability

Abstract

Permasalahan sampah di Indonesia masih didominasi oleh rendahnya praktik pemilahan sampah dari sumber, termasuk di lingkungan sekolah. SD Madani Islami School Purbalingga menghadapi sejumlah tantangan seperti sistem pemilahan sampah yang terstruktur, fasilitas yang terbatas, serta minimnya edukasi lingkungan yang berkelanjutan. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan, membentuk kebiasaan pemilahan sampah sejak dini, dan menciptakan budaya sekolah yang peduli lingkungan melalui implementasi Program Anak Cinta Lingkungan (PACL). Metode yang digunakan adalah Participatory Action Learning System (PALS) yang mengintegrasikan edukasi interaktif berbasis cerita bergambar, praktik langsung pemilahan, lomba kreatif membuat tempat sampah dari bahan bekas, serta pelatihan singkat mengenai daur ulang dan kebersihan lingkungan. Program melibatkan 30 siswa kelas 1–6 dan dilaksanakan melalui tiga tahap: pra-kegiatan, pelaksanaan, dan evaluasi menggunakan instrumen pre-test dan post-test. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan siswa dari skor rata-rata 80% menjadi 100%, disertai perubahan perilaku yang signifikan dalam ketepatan memilah dan membuang sampah. Temuan ini menegaskan bahwa pendekatan edukasi berbasis praktik dengan dukungan guru serta fasilitas pendukung, efektif dalam membangun perilaku sadar lingkungan. Program PACL berpotensi direplikasi pada sekolah dasar lainnya sebagai model edukasi pemilahan sampah yang sistematis dan berkelanjutan.

Abstract

This research aims to analyze the flavonoid compound of beluntas leaves (Pluchea indica L) using maceration and soxhletation extraction methods. Extraction uses 96% methanol solvent with a ratio of 1:10, 1:15, 1:20 w/v and with a soxhletation extraction time of 60 minutes, 120 minutes, 180 minutes at a temperature of 80oC, while the maceration time is 3 days at room temperature. Qualitative testing of flavonoid compounds uses the Shinoda test which is characterized by a change in the color of the sample to yellow or red-orange. The test results of all samples used showed the presence of flavonoid compounds which were characterized by changes in the color of the samples from yellow to red-orange. The research results showed that the best flavonoid content using the maceration extraction method was 51.52 mg QE/g at a ratio of 1:20 w/v, while the flavonoid content using the soxhletation extraction method was 53.96 mg QE/g at a ratio of 1:20 w/v.

Abstract

Fly ash, as waste from burning coal, contains dominant amounts of silica (SiO2), so it can be used as a source of silica. Silica synthesis can be done by reacting fly ash with an alkaline solution and precipitating the silica with an acidic solution. In this research, the variables used are the type of reactant, process temperature and the mass ratio of the raw material to the reactant, with the aim of knowing the silica yield produced. Silica synthesis was carried out using 3M NaOH and KOH with variations in temperature (75, 85, 95, 105 oC), mole ratio of fly ash to NaOH (1:10.09; 1:12.61; 1:15.13) and KOH ( 1:7.34; 1:9.17). The initial fly ash content was carried out by XRF analysis and the silica resulting from the extraction process was calculated by % yield and SEM analysis. The research shows that the highest % yield at a temperature of 950C and mole ratio of 1:15.13 is 105.6% using NaOH solvent and a raw material: reactant ratio of 1:11 of 1.184 grams with yield of 43.05% using KOH solvent, Yields that exceed 100% are caused by impurities that are taken in during the silica extraction process. The silica results in both reactant type variables have an average particle size of 36 -77 nm.
