Abstract

The role of practical work in Organic Chemistry is to provide experience to gain skills and to reinforce concepts that have been obtained from theory and also to increase understanding and to increase interest or motivation. However, practical work has not been an activity that can always be done in high school, especially for chemistry due to facility lack. For this reason, a workshop is needed to increase the understanding of high school chemistry teachers in basic Organic Chemistry, as well as to increase the insight of chemistry teachers in creating practical topics that are in accordance with the facilities available at school. The workshop was held for high school chemistry teachers in Mojokerto. The workshop consisted of an explanation of the basic of Organic Chemistry and the use of Chem Office software, accompanied by practical work in laboratory. The workshop held was successfully added the insights of the teachers and it was hoped that the knowledge obtained would be applied in learning process in their respective high schools.

Abstract

The city of Mataram, the capital of West Nusa Tenggara province, consists of 6 sub-districts and 50 sub-districts and has 28 public and private high schools. Lecturers and students of the Department of Chemistry, who are members of the community service team, on August 5th, 2023 carried out a workshop for chemistry and biology teachers in the City of Mataram. The title of the activity was "Application of Phytochemical Screening as a medium to increase the insight of Biology and Chemistry High School Teachers in Mataran City, NTB as an alternative implementation of Merdeka Belajar". The workshop was held at SMAN 5 Mataram City involving 51 chemistry and biology teachers as participants. The material provided includes Phytochemicals and the Chemdraw application. Both of these topics are given by lecturing and discussion and also complemented by practical activities. The successful of the activity is reflected in the increase in posttest scores compared to the pretest score. Evaluation of activities in the form of filling out the questionnaires by participants also reflected the participant satisfaction, in which the majority of participants gave positive answers to each question. Similar activities remain relevant and still need to be carried out, especially in areas outside Java to broaden teachers' insight

Abstract

The coastal community of Sine Beach, Kalibatur Village, Tulungagung, Indonesia, has long thrived on fishing activities. In response to this, a community development service explores the alternative utilization of coconut, particularly the production of Virgin Coconut Oil (VCO), as a means of economic diversification. By integrating scientific principles with local traditions, the community learned to extract VCO and create various coconut-based products. This initiative not only broadened economic horizons but also fostered environmental sustainability. The programs aims to give economic impact to residents in Pantai Sine Tulungagung.
PHYTOCHEMICAL SCREENING AND ANTIBACTERIAL ACTIVITY OF TENGKAWANG BUKIT (Shorea beccariana) STEM EXTRACT AGAINST Vibrio parahaemolyticus Anisa, Hosia; Mukti, Akhmad Taufiq; Mahasri, Gunanti; Amin, Muhamad; Aminah, Nanik Siti

Abstract

Vibrio parahaemolyticus infection poses a significant challenge in intensive shrimp culture, leading to substantial economic losses. Its common treatments using synthetic antibiotics have been linked to increased risks of antibiotic resistance and residual effects. Therefore, finding environmentally safe and effective natural alternatives is deemed essential. Tengkawang Bukit (Shorea beccariana) stem extract contains antibacterial compounds, including asiatic acid, oleanolic acid, and lupanone, all classified as terpenoids. This study aims to evaluate the antibacterial potential of S. beccariana stem extract through phytochemical screening and a disc diffusion test against V. parahaemolyticus. The screening results confirmed the presence of bioactive compounds, including alkaloids, flavonoids, saponins, tannins, and steroids. The disc diffusion test showed an increase in the inhibition zone with increasing extract concentration, with inhibition diameters ranging from 9.04 ± 0.48 mm to 10.75 ± 0.26 mm. The 17% extract yield indicates a high availability of active compounds. These findings suggest that tengkawang bukit stem extract has potential as a natural antibacterial alternative for controlling V. parahaemolyticus in shrimp culture. This approach could help reduce reliance on synthetic antibiotics and promote sustainable fisheries. Infeksi Vibrio parahaemolyticus merupakan salah satu kendala utama dalam budidaya udang yang menyebabkan kerugian ekonomi signifikan. Penggunaan antibiotik sintetis sebagai pengobatan telah menimbulkan kekhawatiran terkait resistensi dan residu, sehingga diperlukan alternatif alami yang aman dan efektif. Batang tengkawang bukit (Shorea beccariana) diketahui mengandung senyawa antibakteri seperti asam asiatik, asam oleanolik, dan lupanon yang tergolong ke dalam senyawa terpenoid. Studi ini bertujuan untuk mengevaluasi potensi antibakteri ekstrak batang S. beccariana melalui skrining fitokimia dan uji difusi cakram terhadap V. parahaemolyticus. Hasil skrining menunjukkan adanya kandungan senyawa bioaktif berupa alkaloid, flavonoid, saponin, tanin, dan steroid. Uji difusi cakram memperlihatkan zona hambat yang meningkat seiring dengan peningkatan konsentrasi ekstrak, dengan diameter hambatan berkisar 9,04 ± 0,48 mm hingga 10,75 ± 0,26 mm. Rendemen ekstrak sebesar 17% menunjukkan ketersediaan senyawa aktif yang melimpah. Hasil riset ini mengindikasikan bahwa ekstrak batang tengkawang bukit berpotensi sebagai alternatif antibakteri alami dalam pengendalian V. parahaemolyticus pada budidaya udang, sehingga dapat mengurangi ketergantungan terhadap antibiotik sintetis dan mendukung keberlanjutan perikanan.

Abstract

Pemodelan kimia berbasis komputer merupakan topik penting dalam kimia komputasi. Meskipun belum termasuk dalam kurikulum Sekolah Menengah Atas, pendekatan komputasional dapat mendukung pembelajaran yang lebih interaktif dan berfungsi sebagai alat virtual untuk menjelaskan serta memprediksi reaktivitas kimia. Program pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman guru mengenai konsep dan praktik kimia komputasi, serta relevansinya dengan kurikulum. Pelatihan dilakukan melalui ceramah dan sesi praktikum menggunakan Avogadro 1.2.0 dan MOPAC2016. Efektivitas program dievaluasi secara kuantitatif dan kualitatif, sedangkan keberlanjutan dianalisis melalui penugasan di mana para guru merancang rencana integrasi materi ke dalam pembelajaran mereka. Analisis pre-test dan post-test menunjukkan peningkatan signifikan pada nilai peserta, dari rata-rata 44,9 menjadi 62,5 (P < 0,01). Umpan balik kualitatif menunjukkan bahwa para guru mengembangkan ide konkret untuk menerapkan kimia komputasi dalam kegiatan pembelajaran di kelas. Peserta menilai pelatihan ini relevan dengan kebutuhan pengajaran mereka. Program ini meningkatkan kesiapan dan motivasi mereka untuk mengintegrasikan kimia komputasi dalam praktik pembelajaran.
