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

Juk Ayak is the largest and oldest village in Telen District, East Kutai Regency, East Kalimantan Province. The village is the capital city of the Telen District, however there is a little information about Juk Ayak village in today’s digital era. There are several problems faced by the village, some of them came from village administration, in terms of unclear village border, increasing of land opening for oil palm plantation development initiated by locals, ethics education, and less interest of mathematics in elementary school students. The applied method was initial observations together with village officials and the local community regarding the problems they faced. The next step was to identify problems and collect data on resource potential at the moment. Then, we discussed about possible best solutions by involving all parties as outlined in our planned work program. The result of activities and outcomes from the achieved work program were village website making, writing articles for website content, socializing the importance of protecting forest and land from fires, establishing a fire society care (MPA), designing village map, learning social ethics and the introduction of mathematics in interesting and fun way for kids.

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.

Abstract

The Lurai fish, scientifically known as Corica soborna Hamilton, 1882, belongs to the small freshwater fish in the Clupeidae family of the Clupeiformes order. Local communities in the lower Mahakam River, East Kalimantan, have long exploited this species for consumption and trade. At the same time, the biological information regarding this fish, which forms the fundamental basis for its conservation, is yet unknown. This study aimed to analyze the biological aspects and habitat of the lurai fish in the lower Mahakam River. A total of 812 fish samples were analyzed using measuring and weighing methods. The results showed that the fish's length ranged from 42.48 to 63.89 mm and their weight from 0.70 to 2.56 g. Mature lurai fish with 52.48-54.47 mm length dominated the highest mode. The regression model of the length-weight relationship was W= 5×10-6L3.18 for the total sample. The growth pattern of the fish was isometric, and the relative condition factor ranged from 0.765 to 1.123. The sex ratio was 1 male : 1.68 females. The highest percentage of gonadally mature fish was found in February. Fish lengths at first gonad maturity ranged from 52.55 to 53.38 mm for males and 59.94 to 61.25 mm for females. The habitat of the lurai fish is at the edge of the river with vegetation, a muddy bottom, a dissolved Oxygen range of 3.70-4.17 mgL-1, a temperature range of 27.50-28.40 °C, a TDS range of 50-80 mgL-1, a clarity range of 19-29 cm, a water depth range of 2.80-3.60 m, and a current velocity range of 0.65-1.07 mst-1.
