Abstract

Indonesia is one of the centers of sweet potato diversity worldwide. Sweet potatoes have the potential to be developed for food consumption. This research aims to determine the diversity of sweet potato cultivars, their morphological characteristics, and the relationships between local sweet potato cultivars in Bulungan Regency, North Kalimantan. The local sweet potato cultivars were selected using purposive sampling with the exploration method. The morphological characterization of the samples is based on IBPGR (International Board for Plant Genetic Resources) standards. Cluster analysis was conducted to identify the relationships using MVSP software version 3.1. The research identified 27 local sweet potato cultivars in Bulungan Regency. Morphological characterization revealed 41 characters that can differentiate each local sweet potato cultivar. The most influential characteristics include leaf shape, flower surface texture, the position of the stigma, flower surface color, back petal color, center shape and the number of lobes, primary leaf vein color, lobe type, main leaf bone color, stem internode length, and plant type. A flower shape that had not been discovered before, a pentagonal shape with curves, was identified. Cluster analysis divided the cultivars into two major groups with a coefficient range of 0.593 to 0.888 (59.3 to 88.8%). Cluster A consisted of one member, LK-7 (purple sweet potato), while Cluster B consisted of several subgroups with 26 local cultivars. The people of Bulungan Regency use these local cultivars for food, animal feed, and medicinal purposes.

Abstract

Ramalina sp. (Ramalinaceae) is a type of lichen known to contain many active secondary metabolite compounds that have the potential to be used as medicine or medicinal raw materials. One of the biological activities possessed by Ramalina sp. lichen is its anticancer activity. This research aims to isolate and identify active secondary metabolite compounds from the methanol extract of the Ramalina sp. lichen and to find out the cytotoxic activity of the isolated compound against MCF7 breast cancer cells. Compound 1 (usnic acid) was successfully isolated from fraction A. The isolation and purification process was carried out starting with a maceration process using acetone solvent, followed by silica gel column chromatography using a gradient solvent system consisting of n-hexane, n-hexane:EtOAc, EtOAc, EtOAc:MeOH, and MeOH with 5% increment of polarity to obtain 17 fractions (F-1 to F-17). From the 17 fractions obtained, fraction 3 (F-3) and fraction 4 (F-4) (eluted with n-hexane:EtOAc 30%), which had the same TLC profile, were combined and named as fraction A. Compound 1 (50 mg) is a yellow needle crystal that was formed in a bottle of fraction A, which was obtained after the process of combining fractions F-3 and F-4 and solvent evaporation process. The crystals were then separated and purified with CHCl3 and MeOH. Compound 1 was then characterized based on spectroscopic data. Various spectroscopic analysis data, including FTIR, 1D- and 2D-NMR, and LC-ESI-MS, show that Compound 1 is a dibenzofuran derivative compound with 18 carbons (3 from carbonyl groups (C=O) and 3 from methyl groups) and 2 hydroxyl (-OH). Cytotoxicity assay showed that at a low concentration of 18.75 ug/mL, Compound 1 caused a 67.06% decrease in MCF7 viability

Abstract

Peningkatkan kesadaran masyarakat dalam mengurangi risiko penyakit yang ditularkan nyamuk, seperti demam berdarah, malaria, dan chikungunya perlu dilakukan melalui sosialisasi. Pendekatan berbasis komunitas menggunakan metode ovitrap digunakan untuk mengedukasi warga mengenai hal ini. Selama satu bulan pengamatan, metode ini berhasil menunjukkan penurunan signifikan jumlah jentik nyamuk dari minggu ke minggu. Ovitrap, sebagai alat sederhana, memutus siklus hidup nyamuk dengan menjebak telur di wadah khusus berisi air. Selain pengenalan metode, pelatihan diberikan untuk memaksimalkan hasil penerapannya. Monitoring berkala dan kolaborasi dengan kader kesehatan serta pemerintah setempat memungkinkan evaluasi berkelanjutan terhadap keberhasilan program ini. Hasil analisis menunjukkan rata-rata jumlah jentik nyamuk menurun secara konsisten, yang membuktikan efektivitas metode ini dalam menciptakan lingkungan yang lebih sehat dan bebas nyamuk. Kegiatan ini diharapkan dapat direplikasi di wilayah lain sebagai upaya berkelanjutan dalam pencegahan penyakit berbasis lingkungan.

Abstract

Community service is one of the key components of the tri dharma of higher education. This article discusses the community service activities carried out as part of the 50th KKN UNMUL in Olong Pinang Village, a village located in Paser Balengkong District, Paser Regency, East Kalimantan Province. Olong Pinang Village already has an official website, but access to the site had experienced issues, making it necessary to improve its quality. Publications play an important role in introducing and promoting the potential of an area, whether in human resources or natural resources. Therefore, promoting the potential of Olong Pinang Village is necessary to increase its visibility and raise public awareness about the importance of digitalization in this era. The version upgrade and theme changes on the website aim to make the village site more attractive, easily accessible, and sustainably manageable. Additionally, publishing videos of the village’s potential through YouTube is expected to increase the village’s exposure and attract interest from outside communities, ultimately supporting local economic growth.
