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

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.

Abstract

Azadirachta indica, Acalypha indica, and Muntingia calabura are wild plants with antioxidant content capable of treating various diseases. This study aims to evaluate phytochemical compound screening using qualitative tests and to characterize them using FT-IR (Fourier Transform Infrared Spectroscopy) in Azadirachta indica, Acalypha indica, and Muntingia Calabura, as well as to assess total phenolic content (TPC), flavonoid content (TFC), and antioxidant potential. The results showed that Azadirachta indica and Acalypha indica contained alkaloids, flavonoids, tannins, saponins, phenols, glycosides, steroids, and carbohydrates but lacked proteins and triterpenoids. In contrast, Muntingia Calabura leaf extract lacked glycosides, triterpenoids, and carbohydrates. The highest TPC content in Muntingia Calabura extract was 269.88±0.00 mg GAE/gr extract, and the highest TFC was found in Azadirachta indica extract at 676.34±21.85 mg CE/gr extract. The ethanol extract of Azadirachta indica and Muntingia Calabura leaves has very strong antioxidant activity, with IC₅₀ values of 32.76 ± 3.02 ppm and 31.16 ± 1.96 ppm, respectively, while Acalypha indica had an IC₅₀ value of 107.71 ± 3.55 ppm, indicating a moderate level of antioxidant activity. These results support the potential of the three medicinal plants as sources of natural antioxidants. The findings can stimulate further research to isolate key bioactive compounds and perform toxicity tests to support potential applications in the pharmaceutical and food industries.
