Abstract

Stunting is an important problem currently facing Indonesia. The prevalence rate of stunting is still in the high category when compared with WHO standards. NTB Province is one of the areas accelerating stunting reduction, including Kuripan District, West Lombok. Nutrition education programs for mothers are very important to tackle the problem of stunting. Nutrients play an important role in children's growth and development, such as fatty acids. Fatty acids are very good to consume for intelligence, so they can reduce stunting rates. One source of fatty acids is fish oil. The aim of this PkM activity is to provide education to mothers about stunting and how to prevent it, as well as the benefits of fish oil as a nutrient that plays an important role in efforts to prevent stunting. This series of PkM activities are direct outreach activities to the community, in this case the object of the PkM activity is the women reciting the TPQ Miftahul Ulum recitation in Kuripan Village, followed by the activity of distributing fish oil and installing educational posters about stunting and fish oil. The PkM activities ran smoothly and the mothers were very enthusiastic and eager to take part in the PkM activities. This activity provides a comprehensive understanding of stunting and the role of fish oil as an effective solution to prevent and overcome the problem of stunting in society

Abstract

Antioksidan merupakan zat kimia yang membantu menangkal radikal bebas. Antioksidan alami dalam ditemukan didalam tanaman tertentu dan telah terbukti melindungi sel manusia dari kerusakan oksidatif. Tanaman yang mengandung antioksidan alami dan belum termanfaatkan secara maksimal antara lain adalah kelor, nyamplung dan ketapang. Kegiatan pengabdian ini dilakukan dengan memberikan edukasi kepada ibu-ibu PKK desa Bagik Polak Lombok Barat untuk meningkatkan pengetahuan akan bahaya antioksidan sintetik yang terkandung dalam berbagai sediaan kosmetik. Sumber antioksidan alami dapat diperoleh dari tanaman pangan non komersil. Salah satu tanaman yang dimanfaatkan aktivitasnya sebagai antioksidan yaitu tanaman kelor (Moringa oleifera Lam). Ekstrak daun kelor mempunyai aktivitas antioksidan karena mengandung senyawa flavonoid dan beta karoten. Sedangkan minyak biji kelor mengandung asam-asam lemak yang memiliki aktivitas antioksidan yang baik. Kegiatan pengabdian ini dilaksanakan dalam beberapa tahap, yaitu: (1) Sosialisasi pengetahuan tentang antioksidan, sumber antioksidan dan bahaya dari antioksidan sintetik (2) Pelatihan pembuatan bahan pangan menggunakan sumber antioksidan alami (3) evaluasi hasil kegiatan pengabdian. Ibu-ibu kelompok Wanita PKK sangat antusias dan semangat selama mengikuti kegiatan pengabdian. Kegiatan ini telah memberikan tambahan pengetahuan tentang antioksidan alami dalam minyak nabati non pangan yang berasal dari tumbuhan dan tanaman yang tidak termanfaatkan dengan baik.

Abstract

Sound healing, or commonly referred to as music therapy using Acoustic Sound for Wellbeing (ASW) Moringa seed oil (Moringa oleifera Lam.) has significant potential for use in various industrial sectors, including food, pharmaceuticals, and cosmetics. One of the critical factors influencing oil extraction efficiency is preheating treatment and extraction process duration. This study aims to evaluate the effect of varying preheating temperatures and Soxhlet extraction times on the yield of Moringa seed oil, as well as to determine the most optimal extraction conditions. The extraction process was conducted using the Soxhlet method with n-hexane as the solvent. Preheating temperatures used in this study ranged from room temperature to 50°C, 60°C, and 70°C, with extraction times of 2, 4, and 6 hours. The results showed that preheating treatment on moringa seeds and extraction duration had a significant impact on oil yield. The optimal conditions were achieved at a preheating temperature of 70°C with an extraction time of 6 hours, yielding the highest oil recovery of 41.74%.

Abstract

Epoxy is a cyclic ether compound that contains an oxirane group and has been widely applied as a stabilizer, plasticizer in polyvinyl chloride (PVC), surfactant, pesticide raw material, and as a polymer resin coating. The raw materials in epoxy synthesis come from petroleum derivatives, which are non-renewable natural resources. Therefore, there is a need for alternative raw materials that can be renewed, such as vegetable oil. In this study, nyamplung seed oil was used. Epoxy synthesis is usually carried out using carboxylic acid epoxidation with the help of an acid catalyst. This research aims to determine the effect of the type of acid catalyst and its concentration on the epoxidation reaction of nyamplung seed oil and the characterization of the epoxy produced. The research results show that using an acid catalyst can increase the formation of oxirane groups at a certain concentration, where the highest oxirane number value was obtained when using the H2SO4 catalyst, namely 3.15%. The resulting epoxy is pale yellow, has a typical absorption area (COC) at a wave number of 825 cm-1, an iodine value of 13.96 g iod/100 g, a viscosity of 20.80 cP, and a relative per cent conversion to oxirane of 73.4 %

Abstract

Moringa seed oil is a vegetable oil that has many benefits for health and the pharmaceutical industry. Moringa seed oil can be extracted either chemically or mechanically. This research aims to characterize moringa seed oil’s physicochemical properties and fatty acid composition using soxhletation chemical extraction and screw-pressing mechanical extraction with various pretreatment temperatures of 50, 60, and 70°C. The research showed that the highest yield of moringa seed oil, 41.74%, was obtained at an initial treatment temperature of 70°C using the soxhletation method for 6 hours. The acid value of moringa seed oil from soxhletation is 2.01 mg KOH/g, and screw pressing is 4.37 mg KOH/g. The iodine number from soxhletation was 66.62 mg iod/100g, and screw pressing was 60.27 mg iod/100g. The density of the oil from soxhletation and screw pressing is 0.922 mg/mL and 0.934 mg/mL, respectively, with an oil viscosity of 3.298 cP and 3.424 cP. The results of GC-MS analysis show that moringa seed oil from soxhletation has an oleic acid composition of 40.92%, while the screw pressing has an oleic acid composition of 22.50%. This finding demonstrates the influence of extraction methods on the fatty acid profile, particularly the concentration of oleic acid, a key component of moringa seed oil. These results contribute to understanding how specific extraction techniques can optimize the quality of moringa seed oil.

Abstract

Muhammadiyah is one of Indonesia's most prominent Islamic religious organizations, growing rapidly as a leading religious organization in health and education. This research examines the challenges faced by the Muhammadiyah branch in the Padang Lawas Utara district. This study explores the dynamics between Muhammadiyah's institutional practices and the cultural frameworks within which they operate. The study utilizes a case study method to provide an in-depth understanding of the interactions between Muhammadiyah's organizational practices and local cultural elements. Data collection involves semi-structured interviews with key informants, participant observation, and document analysis of relevant organizational records and cultural artifacts. Data analysis was conducted using thematic analysis. A triangulation method is employed to ensure the validity and reliability of the data. The findings indicate that while local traditions can enhance the acceptance of Muhammadiyah's reformist ideals, they can also present challenges when cultural norms conflict with the organization's objectives. They are reluctant to accept the Muhammadiyah ideology due to the incompatibility between local culture and Islamic teachings.

Abstract

This Community Service activity was conducted at SMA Negeri 1 Batukliang, Central Lombok, a senior high school offering a science (IPA) program and supported by the availability of a chemistry laboratory. The school faces several challenges, including a curriculum that has yet to incorporate real-life applications of chemistry, limited student understanding of chemical separation techniques, and inadequate laboratory facilities and infrastructure. This community service program aimed to introduce and demonstrate various separation techniques including extraction, distillation, and chromatography through interactive lectures, educational videos, and simple hands-on experiments, including processes like extraction, Soxhletation, and distillation. Through this activity, students not only gained theoretical knowledge but also practical experience in applying separation techniques and observing the products generated from these processes. This initiative aligns with the Sustainable Development Goals (SDGs), particularly in supporting quality education. The program is expected to enhance students’ scientific literacy and serve as an initial step toward raising awareness of the importance of chemistry in everyday life.
