Abstract

The UV-Vis spectrophotometer is commonly utilized for sample analysis in practicums, research, and community service. The analysis method employed in these activities must utilize a proven analytical technique to ensure the accuracy, precision, and accountability of the produced results. Hence, one of the aims of this study was to verify the vitamin C analysis technique for its linearity, accuracy (% recovery), precision (% RSD), limit of detection (LOD), and limit of quantitation (LOQ). Additionally, the validated analytical method will be employed to analyze the vitamin C content in pempaken fruit (Durio kutejensis Hassk (Becc.)) and kalangkala fruit (Litsea garciae Vidal). The linearity of a method was assessed by examining the correlation between the concentration (x-axis) and the response (y-axis). Percentage recovery was determined by quantifying the concentration of vitamin C in the sample and subsequently quantifying the concentration of vitamin C in the sample following the addition of a known quantity of a standard solution. The calculation of % RSD involves dividing the standard deviation (SD) by the average level (µg/mL) and then multiplying the result by 100%. LOD was determined by dividing the standard deviation by the slope value . Meanwhile, the determination of LOQ was accomplished by the use of a mathematical formula . South Kalimantan is abundant in medicinal plants, such as pampakin and kalangkala. Hence, another objective of this study was to assess the antioxidant activity of the extracts from these two plants using the DPPH method, employing a UV-Vis Spectrophotometer for analysis. The linearity, detection limit, quantitation limit, accuracy, and precision of the validated vitamin C analysis method were as follows: 0.999, 0.50ppm, 5.02ppm, 99.45-101.48%, and 0.03-1.33%, respectively. A 1.0 g sample of kalangkala and pampakin fruit contained 0.24 mg and 0.13 mg of vitamin C, respectively. The antioxidant activity test revealed that the kalangkala leaf extract exhibited potent antioxidant properties, with the solvents ranked in the following order of efficacy: methanol (IC50=23.03 µg/mL) > ethyl acetate (IC50= 27.16 µg/mL) > methylenechloride (IC50= 27.45 µg /mL) > n-hexane (IC50= 32.01 µg/mL). Pampakin leaves, kalangkala fruit, and pampakin fruit showed the highest antioxidant activity in methanol extract with IC50, respectively 50.29, 48.70, and 45.30 µg/mL. Based on the findings of this study, the vitamin C analysis method utilizing a UV-Vis spectrophotometer passes the validation requirements, and the antioxidant activity of pampakin and kalangkala fruit on DPPH free radicals is most likely attributable to the vitamin C found in these fruits. Meanwhile, extracts of the two plants derived from methanol demonstrated the strongest antioxidant activity when compared to other solvents such as n-hexane, methylene chloride, and ethyl acetate.

Abstract

Kalangkala (Litsea garciae Vidal) dikenal sebagai tumbuhan dengan berbagai bioaktivitas, menjadikannya kandidat yang menjanjikan untuk aplikasi farmasi dan pengobatan tradisional. Penelitian ini bertujuan untuk  mengetahui kandungan fitokimia dan aktivitas antibakteri pada ekstrak metanol daun tumbuhan tersebut. Metode skrining fitokimia dilakukan  untuk menganalisis  kandungan alkaloid, triterpenoid, flavonoid, dan fenolik dalam ekstrak metanol. Aktivitas antibakteri dievaluasi secara in vitro terhadap bakteri Gram positif (Staphylococcus aureus) dan Gram negatif (Salmonella typhimurium). Hasil penelitian menunjukkan bahwa ekstrak metanol mengandung senyawa triterpenoid, fenolik, dan flavonoid. Pengujian antibakteri menunjukkan bahwa S. aureus menunjukkan zona penghambatan sebesar 12,00±0,08 mm, 16,00±0,12 mm, dan 19,00±0,22 mm pada konsentrasi ekstrak masing-masing 25%, 50%, dan 100%. Demikian pula, S. typhimurium menunjukkan zona penghambatan sebesar 18,00±0,23 mm, 20,00±0,11 mm, dan 22,00±0,07 mm pada konsentrasi yang sama. Hasil ini mengindikasikan potensi L. garciae Vidal sebagai agen antibakteri.

Abstract

Abstrak Kisaran 250-300 ribu tahun lalu sampai saat ini, proses kebinekaan atau keanekaragaman (diversity) biologis homo sapiens sedang berproses. Kebinekaan biologis manusia ini menelurkan secara kongruen pada bidang budaya dan bahasa. Orientasi ulasan kebinekaan ini mengutamakan pada asal usul kebinekaan budaya saja di Indonesia, yang diwakili suatu situs candi Jawi, di Pasuruan. Adapun ulasan kebinekaan biologis/genetika dan bahasa adalah sebagai tambahan. Monumen artifak kebinekaan ini dapat direnungkan dengan jelas melalui candi Jawi itu, candi yang merujuk pada pararelisme Siwa (hindu) dan Budha, merujuk pada kebinekaan Siwa dan Budha, merujuk pada ajaran dewi Prajna Paramita. Program kreatifitas masyarakat (PKM) kali ini melibatkan generasi Z untuk memberi apresiasi asal-usul konsepsi kebinekaan sebagai falsafi visioner Jawa. Metode structural equation modelling (SEM) digunakan untuk koleksi responden. Hasil ujinya, berturut-turut sebagai berikut; sangat mengerti (0%), mengerti (96%), kurang mengerti (4%) dan tidak mengerti (0%). Secara umum, responden generasi Z mengerti atas konsepsi kebinekaan dalam keberagamaan, kebinekaan dalam genetika dan kebinekaan dalam bahasa.Kata kunci: Kebinekaan, candi Jawi, Sapiens

Abstract

Laboratorium ilmu pengetahuan alam (IPA) seperti labotarorium kimia, fisika, dan biologi merupakan laboratorium dengan risiko tinggi dan memerlukan pengelolaan yang baik agar kegiatan di laboratorium dapat berjalan dengan lancar dan aman. Penerapan GLP (Good Laboratory Practice) dan K3 (kesehatan dan keselamatan kerja) di laboratorium berperan penting dalam meminimalkan risiko dan kecelakaan kerja di laboratorium. Olehnya itu, tujuan kegiatan pelatihan ini adalah memberikan pemahaman terhadap guru, pengelola laboratorium dan siswa mengenai pentingnya penerapan GLP dan K3 di laboratorium. Metode yang digunakan untuk memberikan pemahaman kepada guru, pengelola laboratorium, dan siswa kelas XII MAN 2 Hulu Sungai Selatan (HSS) adalah pemaparan materi di kelas. Berdasarkan hasil kuesioner yang dibagikan, peserta memberikan respon yang positif terhadap kegiatan ini dan memiliki pemahaman yang baik terkait GLP dan K3 setelah mengikuti pelatihan. Kegiatan ini dapat mewujudkan GLP dan K3 di laboratorium sehingga praktikum, penelitian, dan pengabdian pada masyarakat dapat berjalan dengan aman dan lancar.

Abstract

The Peat Hydrological Area (KHG) in South Kalimantan in 2023 covered approximately 238,465 hectares. In Pandahan Village, Tanah Laut Regency, approximately 50 hectares of land are covered with wild galam plants. Galam plants are native to peatlands that naturally associate with endophytic fungi and have the potential to produce essential oils of high economic value as an Indonesian export commodity. Until now, galam has only been used by some communities for firewood without further processing. This Student Creativity Program (PKM) aims to empower farmer groups to acquire the knowledge, skills, and managerial abilities to process galam leaves into essential oils. Activities are carried out using a participatory method through demonstrations and simulations. The program is implemented in three stages: planning, implementation, and evaluation. The activity took place from July 5–19, 2025, in Pandahan Village with 30 participants. Pre-test results showed that only 10% of participants knew the process of processing galam leaves. Following the training and mentoring, post-test results improved significantly, with 100% of participants able to successfully process galam leaves into essential oil. The program continues through monitoring activities to ensure ongoing skill improvement.
