Abstract

Antioxidants are chemical substances that have the ability to protect body cells from damage caused by excessive oxidation reactions. One of the uses of antioxidants from natural materials is jarak pagar leaves (J. curcas). This study aims to determine the antioxidant and cytotoxic activity against shrimp larvae from ethyl acetate extract of J. curcas leaves. Ethyl acetate extract from J. curcas leaves was extracted using the soxhletation method. Phytochemical testing was carried out using the tube method, antioxidant testing using the DPPH method and cytotoxic using the BSLT method. The results of the research showed that J. curcas contained secondary metabolite compounds in the form of flavonoids and polyphenols, the antioxidant activity test of Ethyl acetate extract from J. curcas leaves and the comparison control (vitamin C) produced an IC50 of 71,79±0.35 ppm and 8.78±0.21 ppm, respectively. The cytotoxic test of the ethyl acetate extract of J. curcas leaves contains active compounds that are toxic to the shrimp larvae with an LC50 of 72.13 ppm (LC50≤1000 ppm). The most effective concentration in free radicals scavenging is 160 ppm. Based on the results obtained, the ethyl acetate extract of J. curcas showed strong antioxidant activity and potential as an anticancer agent.

Abstract

Abstrak: Agrowisata Cipta Rasa Pak Slamet di Palangka Raya menghadapi masalah pencurian buah yang mengganggu keamanan. Tujuan pengabdian ini adalah meningkatkan keamanan dan pengetahuan masyarakat lokal tentang energi terbarukan melalui penerapan sistem penerangan berbasis panel surya dengan sensor gerak. Metode yang digunakan meliputi sosialisasi, penyuluhan, dan workshop praktis kepada 15 anggota komunitas lokal. Evaluasi dilakukan dengan survei pre dan post-test untuk mengukur peningkatan keterampilan teknis (hard skill) dan pemahaman energi terbarukan. Hasil menunjukkan peningkatan keterampilan teknis peserta sebesar 50% dan peningkatan pemahaman tentang pentingnya energi terbarukan dari 30% menjadi 85%. Selain itu, sistem penerangan berhasil mengurangi pencurian buah sebesar 70%, meningkatkan nilai ekonomis agrowisata. Program ini berhasil meningkatkan keamanan dan keterampilan masyarakat, serta mendukung pariwisata berkelanjutan. Abstract: Pak Slamet's Cipta Rasa Agrotourism in Palangka Raya faces fruit theft issues affecting security. The program aims to enhance security and local community knowledge about renewable energy by implementing a solar panel-based lighting system with motion sensors. Methods included socialization, counseling, and practical workshops with 15 local community members. Evaluation was conducted using pre- and post-surveys to measure improvements in technical skills (hard skills) and understanding of renewable energy. Results showed a 50% increase in participants' technical skills and an increase in awareness of renewable energy from 30% to 85%. Additionally, the lighting system reduced fruit theft by 70%, enhancing the economic value of agrotourism. This program successfully improved security and community skills, supporting sustainable tourism.

Abstract

Abstrak: Komunitas KKSS Palangka Raya menghadapi tantangan dalam budidaya ikan air tawar, termasuk kualitas air yang buruk dan pertumbuhan ikan yang tidak optimal, yang menghambat produktivitas perikanan. Program pengabdian ini bertujuan untuk meningkatkan keterampilan 18 anggota komunitas dalam menerapkan teknologi nano bubble sebagai solusi inovatif. Metode yang digunakan meliputi sosialisasi, penyuluhan, diskusi kelompok terarah (FGD), dan praktik langsung penerapan teknologi di kolam ikan mitra. Evaluasi dilakukan dengan wawancara dan observasi untuk mengukur perubahan keterampilan dan hasil budidaya pasca penerapan teknologi. Hasilnya menunjukkan bahwa teknologi nano bubble secara signifikan meningkatkan kualitas air dan mempercepat pertumbuhan ikan, serta meningkatkan keterampilan peserta dalam pengoperasian dan pemeliharaan sistem sebesar 80%. Peningkatan keterampilan ini berkontribusi pada peningkatan produktivitas perikanan di kawasan tersebut, sekaligus menjadi model untuk pengelolaan perikanan air tawar di wilayah Palangka Raya.Abstract: The KKSS Palangka Raya Community faces challenges in freshwater fish farming, including poor water quality and suboptimal fish growth, which hinder aquaculture productivity. This community service program aimed to enhance the skills of 18 community members in applying nanobubble technology as an innovative solution. The methods employed included socialization, counseling, focus group discussions (FGD), and hands-on practice in applying the technology in the community's fishponds. Evaluation was conducted through interviews and observations to measure changes in skills and farming outcomes after the technology's implementation. The results indicated that nanobubble technology significantly improved water quality and accelerated fish growth, while also enhancing participants' skills in operating and maintaining the system by 80%. This skill enhancement contributed to increased aquaculture productivity in the area and serves as a model for freshwater fishery management in the Palangka Raya region.

Abstract

The increasing demand for natural UV-protective agents has led to the exploration of plant-based bioactive compounds. Yellow root (Arcangelisia flava) extract is traditionally used in medicine and contains flavonoids, alkaloids, and terpenoids with potential photoprotective properties. This study aimed to characterize the chemical composition of A. flava extract and evaluate its UV-absorbing properties using UV-Vis and FTIR spectroscopy. The extract was obtained through maceration with ethanol, followed by spectroscopic analysis. The UV-Vis spectrum (200–400 nm) revealed multiple absorption peaks, particularly at 270 nm, 292 nm, 306 nm, 340 nm, 354 nm, 360 nm, and 396 nm, indicating the presence of UV-absorbing compounds. FTIR analysis confirmed the presence of hydroxyl (-OH), carbonyl (C=O), and aromatic (C=C) functional groups, which are characteristic of flavonoids and other bioactive compounds. These findings suggest that A. flava extract has potential as a natural UV-protective agent. Further studies on compound isolation, fractionation, and photostability assessments are required to optimize its purity and effectiveness in sunscreen formulations.
