Abstract

Tofu dregs waste contains 30.4% cellulose content, while kepok banana peel has high cellulose content (60-65%), hemicellulose 6-8%, and lignin 5-10%. The purpose of this study was to determine the process of making natural paper from tofu dregs waste and kepok banana peel waste as an alternative raw material for wood substitutes and to find out the characteristics of natural paper produced from tofu waste fiber and kepok banana peel waste based on SNI 287:2010 (including test water content) and SNI 6588-1:2010 (including pH acidity test). Based on the results of research that has been carried out, the optimum composition in making paper from tofu dregs and kepok banana peels is 50:50% variation. The temperature and time of heating and the optimum concentration of sodium hydroxide solution was 120 oC for 90 minutes with sodium hydroxide solution concentration of 10.0%, pulp content of 46.45%, cellulose content of 53.3%, and lignin content of 46.67%. All levels obtained have met the requirements of SNI. Based on the FT-IR spectrum analysis, tofu dregs and kepok banana peels are suitable for use as raw materials for making paper because they contain cellulose. Based on the SEM analysis, the morphological surface structure, the tighter the fiber bonds, this proves that the diameter of the resulting fiber is very small, because the smaller the fiber diameter, the better the mechanical properties.

One of the herbal plants with antibacterial properties that it can use in solid antiseptic soap is lemon peel (Citrus limon (L.) Burm.F.). This study aims to determine the optimum composition of antiseptic solid soap preparations from the ethanolic extract of lemon peel based on the requirements set by SNI 06-4085-1996 and the antibacterial activity test. The antibacterial activity test was carried out by the good method. Examination of Simplicia characteristics was carried out by phytochemical screening test. The antiseptic solid soap preparation was performed by organoleptic test, pH test, homogeneity test, high foam test, and antibacterial activity test. The concentration variations of antiseptic solid soap preparations were F1(5%), F2(10%), and F3(15%). Based on the results of research that has been carried out, the results of phytochemical screening tests for lemon peels (Citrus limon (L.) Burm.F.) contain secondary metabolites, namely alkaloids, flavonoids, and triterpenoids that function as antibacterial. Antiseptic solid soap made from ethanolic extract of lemon peel has met the requirements set by SNI 06-4085-1996, namely a solid and homogeneous soap with a lemon scent with a pH of 8.71-10.52, high foam 4.7-4.9 cm, as well as free alkali in a safe condition against the skin. Based on the results of the antibacterial activity test of solid antiseptic soap, the ethanolic extract of lemon peel (Citrus limon (L.) Burm.F.) can inhibit the growth of Staphylococcus aureus bacteria. At a concentration of F1(5%) has a zone of moderate inhibition of 10.26 mm; at concentration F2(10%) has a strong inhibition zone of 11.78 mm; at the concentration of F3(15%) has a strong inhibition zone of 12.57 mm. Lemon peel extract can be formulated into a solid antiseptic soap with an optimum concentration of F3 (15%).

Abstract

Background: The primary reason for the immiscibility of polyethylene (PE) and polyamide (PA) lies in their differing polarities and surface tension energies. Objective: This study aims to investigate the impact of LDPE-g-AO compatibilizer on PE/PA blends. Method: The method employed involves blending using an internal mixer. Results: SEM analysis reveals that the morphology of PE/PA blends without LDPE-g-AO compatibilizer is non-homogeneous and incompatible. However, the addition of 2% LDPE-g-AO compatibilizer results in improved compatibility of the PE/PA blend, characterized by homogeneous and compatible surface adhesion properties, with no visible voids. Conclusion: In conclusion, this research underscores the effectiveness of LDPE-g-AO compatibilizer in bridging two previously immiscible polymers, PE and PA, thereby enhancing their overall compatibility

Abstract

The repeated use of cooking oil at high temperatures can significantly degrade its quality, as indicated by darkened color, unpleasant odor, elevated peroxide value (PV), and free fatty acid (FFA) levels. This deterioration can contribute to health risks such as obesity, high cholesterol, heart disease, and cancer. This study investigated the effectiveness of combined activated carbon and bentonite adsorbent in reducing peroxide value and free fatty acid levels in used cooking oil. The purification method involved an adsorption process using a combination of activated carbon derived from mangosteen peel waste and bentonite. The carbonization process was carried out at 600°C for 3 hours, followed by chemical activation with H?PO? at varying concentrations of 1M, 3M, and 5M. Bentonite was activated using 5M HCl. The results demonstrated that 5 grams of activated carbon from mangosteen peel, treated with 5M H?PO?, and bentonite activated with 5M HCl, were highly effective in lowering the peroxide value and free fatty acid levels in used cooking oil. Initially, the PV of the untreated used cooking oil was 16 meq O?/kg, reduced to 3.6 meq O?/kg after treatment with the combined adsorbents. Similarly, the FFA content decreased from 2.2% to 0.09%. Both peroxide value and free fatty acid levels met the standards set by SNI 3741:2013. In conclusion, using activated carbon and bentonite is an efficient method for purifying used cooking oil, as their strong adsorption capacity effectively reduces peroxide value and free fatty acid levels.

Abstract

Diabetes Mellitus (DM) is a chronic condition with increasing prevalence worldwide, including in Indonesia, where the number of affected individuals reached 10.7 million in 2021. One of the main factors contributing to the rising risk of DM in adolescents is obesity, often influenced by unhealthy lifestyle habits. Therefore, education on maintaining an ideal body weight is essential to prevent DM in this age group. This Community Service Program aims to educate the students of SMA Swasta Al-Azhar Medan about the importance of maintaining an ideal body weight to prevent DM. The program combines lectures, interactive discussions, and hands-on activities. It includes a pre-test, educational content delivery, practical exercises, and a post-test. 100 students participated, covering topics such as the relationship between body weight and DM, healthy eating habits, physical activity, and how to monitor weight and calculate Body Mass Index (BMI). The results show significant improvements in students' knowledge about DM, healthy eating, and physical activity. Knowledge of DM increased by 45.5%, understanding of healthy eating improved by 26.1%, and awareness of physical activity grew by 24.3%. Additionally, the average BMI of students decreased by 2.4%, indicating positive lifestyle changes. In conclusion, the program successfully improved students' understanding and encouraged behavioral changes to prevent DM. The increase in knowledge, healthier eating habits, greater physical activity, and reduction in BMI highlight the effectiveness of the educational approach. This program can potentially serve as a model for promoting healthy lifestyles to prevent DM in adolescents.

Abstract

Kayu manis, dengan kandungan kumarin dan transcinnamaldehyde yang signifikan, telah menarik minat dalam penelitian sebagai agen antikoagulan alami. Kumarin, salah satu komponen utamanya, telah terbukti menghambat sintesis protrombin, menghasilkan efek antikoagulan yang menjanjikan. Penelitian ini bertujuan untuk mengeksplorasi efek antikoagulan dari ekstrak kulit kayu manis secara eksperimental. Hasil menunjukkan bahwa penambahan ekstrak dengan berbagai volume ke dalam darah menghasilkan variasi dalam morfologi sel darah merah. Ekstrak kulit kayu manis dengan volume 80 µL, 120 µL, dan 160 µL pada 1 ml darah di dapatkan sel darah masih berkelompok dan berbentuk bulat tidak sempurna. Sedangkan pada ekstrak kulit kayu manis volume 180 µL didapatkan hasil sel yang sempurna. Meskipun ekstrak kayu manis tidak dapat sepenuhnya menggantikan peran EDTA sebagai antikoagulan, namun memiliki kemampuan dalam menghambat proses pembekuan darah. Kesimpulan dari penelitian ini mengindikasikan bahwa ekstrak kulit kayu manis dapat berfungsi sebagai antikoagulan yang memperlambat proses pembekuan darah, memberikan landasan untuk penelitian lebih lanjut dalam bidang ini.
