Abstract

Way Belerang Simpur is a sulfur-containing hot spring that serves as a popular tourist destination for hot spring baths. This study aims to evaluate the water quality of the spring using physical, chemical, and biological parameters. Water samples were taken from three points: the source (Point 1), the bathing area (Point 2), and the downstream flow (Point 3). The parameters analyzed include temperature, pH, dissolved oxygen (DO), odor, hydrogen sulfide (H2S), biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total coliform bacteria. Standard testing methods such as mercury thermometers, pH meters, spectrophotometry, and SNI protocols were used. Results show that temperature and odor meet national standards for safe water, but pH levels were highly acidic, exceeding acceptable limits for public bathing. DO levels were adequate to support aquatic life, while BOD, COD, and H2S were within acceptable limits. The biological analysis revealed very low levels of total coliform bacteria, making the water microbiologically safe. Overall, the water quality at Way Belerang Simpur is suitable in terms of contamination levels but presents risks due to its high temperature and low pH, especially for prolonged exposure.

Abstract

This study aims to evaluate the effect of Extremely Low Frequency (ELF) magnetic field exposure on chlorophyll content in aged rice (Oryza sativa L.) seeds during the vegetative phase. Chlorophyll is the primary pigment in photosynthesis, playing a crucial role in light absorption and the conversion of energy into organic matter essential for plant growth. The research method used was a completely randomized design (CRD) with ELF magnetic field exposure treatments at an intensity of 0.2 mT for 3 minutes 54 seconds, 7 minutes 48 seconds, 11 minutes 42 seconds, and a control treatment without exposure. The results showed that (1) ELF magnetic field exposure for 11 minutes 42 seconds produced the highest chlorophyll a, chlorophyll b, and total chlorophyll content compared to other treatments. (2) The control treatment (P0) resulted in lower chlorophyll a, chlorophyll b, and total chlorophyll content than the P1, P2, and P3 treatments. (3) Longer exposure durations, such as in the P3 treatment, were proven to significantly increase chlorophyll content, potentially optimizing the photosynthesis process in rice plants.

Abstract

Changes in texture and sucrose content in California papaya and kepok bananas after harvest due to metabolic processes can reduce the quality of the fruit. This research investigated the changes in sucrose content and texture during the maturation process of California papayas and kepok bananas. The observed parameters included physical properties, such as texture variations and sucrose levels in the fruit. The research followed a qualitative approach. The research results are described descriptively. This study showed a change in the texture of the kepok banana and California papaya in the ripening process. Changes in the texture of kepok bananas decreased from 3.66 kg/cm on day 2 to day 12 after harvesting from 3.66 kg/cm to 0.56 kg/cm. California papayas from 3.63 to 1.36 kg/cm2. California papayas from 3.63 to 1.36 kg/cm2. The highest sucrose content in the ripening process occurred in kepok bananas and California papayas, respectively, at 0.45? Brix on day 12 and 11.38? Brix on day 10.

Abstract

Masyarakat secara luas memanfaatkan tanaman pisang (Musa spp.) dalam kehidupan sehari-hari mereka. Penelitian ini dilakukan untuk mengidentifikasi jenis-jenis tanaman pisang yang berbeda, organ tanaman yang digunakan dan aplikasinya dalam bidang pangan, budaya, dan pertanian. Metode penelitian yang digunakan adalah kualitatif, dan sampel dikumpulkan melalui teknik purposive sampling dengan kelompok informan terdiri dari 2 tokoh adat, 2 penjual pisang sebagai informan kunci, 25 warga masyarakat Desa Makarti sebagai informan utama, dan satu tokoh masyarakat sebagai informan tambahan.dan snowball sampling. Data dianalisis melalui analisis deskriptif kualitatif dan uji triangulasi digunakan untuk memastikan keakuratan data, meliputi triangulasi sumber, teknik pengumpulan data, dan waktu. Berdasarkan hasil penelitian menemukan bahwa 11 jenis pisang, yaitu janten, kepok, panjang, ambon, barlin, raja, byar, asam, awak, mas, dan susu, dimanfaatkan dalam bidang makanan, budaya, dan pertanian. Masyarakat desa Makarti menggunakan batang, buah, daun, dan bunga dari tanaman pisang. Bidang pangan, pisang digunakan sebagai bahan dasar pembuatan beberapa makanan tradisional dan daunnya dimanfaatkan sebagai pembungkus makanan. Bidang praktik budaya, pisang digunakan dalam penyembahan, cok bakal, dan seni tradisional. Bidang pertanian, pisang dapat digunakan sebagai pupuk kompos, perlindungan bibit, dan budidaya.

Abstract

Indonesia is renowned for its high biodiversity and rich cultural heritage, particularly in traditional medicine practices among indigenous communities. The Coastal Lampung ethnic group in Pesisir Selatan, West Pesisir Regency, preserves a wealth of ethnomedicinal knowledge that has been underdocumented. This study aims to analyze the diversity, usage, and cultural significance of medicinal plants used by this community to support conservation efforts and provide a foundation for pharmacological research. Employing qualitative and quantitative ethnobotanical methods, including semi-structured interviews and field observations with 35 purposively selected informants, data were analyzed using the Index of Cultural Significance (ICS) and Species Use Value (SUV). A total of 79 medicinal plant species from 44 families were identified, used to treat ailments such as wounds, fever, cough, stomach disorders, and postpartum care, with leaves being the most commonly utilized plant part. Curcuma longa L., Zingiber officinale Rosc., and Citrus limon (L.) Osbeck had the highest cultural significance and use values, highlighting their importance in local healthcare. These findings underscore the critical need to conserve both ethnomedicinal knowledge and biodiversity, as well as to pursue pharmacological validation of key species, supporting the integration of traditional knowledge into sustainable health and biodiversity management strategies in Indonesia

Abstract

The importance of food security as part of the Sustainable Development Goals (SDGs), with a focus on local upland rice varieties from Lampung that are drought tolerant but have limitations in seed viability and vigor after storage. The study aims to evaluate the effect of magnetic field exposure on the viability and vigor of upland rice seeds. The method used involves exposing the seeds to a magnetic field for durations of 3, 7, and 11 minutes, followed by measuring parameters such as germination percentage, mean germination time (MGT), coefficient of velocity of germination (CVG), and vigor index. The results showed that magnetic field exposure for 3 minutes produced the best results in several parameters, although not all differences were statistically significant. The magnetic field has the potential to improve the quality of upland rice seeds, but the optimal duration of magnetic field exposure cannot yet be determined
