Abstract

Nowadays some efforts are being made to reduce obesity by using drugs that aim to reduce appetite of the drug users. However, the use of drugs still has harmful side effects. Endophytic fungi originating from the Dayak onion plant are thought to have secondary metabolites that have potential as anti-obesity. The aims of this study were to determine the compounds produced by endophytic fungi of Dayak onion and to determine the potential components as inhibitors of pancreatic lipase enzymes. Samples of Dayak onions were collected from Palangka Raya using purposive sampling method. Isolation of endophytic fungi was conducted using surface sterilization method and the isolates were grown on PDA. Isolates were characterized and fermented on PDB for 14 days. The selected isolate was analyzed by using GCMS then molecular docking was performed using Autodock Vina and PyRx. The research results showed that there were 7 isolates of endophytic fungi isolated from leaves and roots tissues of Dayak onion. GCMS analysis showed that EBD1 contains 38 compounds. Molecular docking analysis showed that 1,3-Di-O-Acetylpentopyranose, a test ligand, has the closest binding affinity value (-6.6 kcal/mol) to orlistat (control) (-6.8 kcal/mol). Thus, it has the potential as an inhibitor of pancreatic lipase enzyme protein.

Abstract

Penyakit demam berdarah merupakan masalah kesehatan masyarakat di Indonesia terutama pada musim penghujan. Penyakit ini ditularkan oleh virus dengue melalui nyamuk Aedes aegypti. Provinsi Kalimantan tengah menempati urutan tiga besar dalam angka penyakit demam berdarah. Salah satu penangangan yang dapat dilakukan untuk melakukan pencegahan demam berdarah adalah dengan memanfaatkan bahan alam yaitu ekstrak dari serai (Cymbopogon citratus) atau serai wangi (Cymbopogon nardus). Pada umumnya serai digunakan sebagai bumbu dapur, sementara serai wangi tidak terlalu dimanfaatkan. Memperhatikan hal-hal tersebut, maka pembuatan lilin anti nyamuk dari ekstrak serai wangi dapat menjadi salah satu solusi dalam mengatasi penyakit demam berdarah dan pengetahuan ini patut disosialisasikan kepada masyarakat. Metode yang digunakan dalam sosialisasi ini berupa ceramah dan pembagian sampel lilin anti nyamuk. Sementara materi ceramah yang disosialisasikan adalah tentang bahaya penyakit demam berdarah, pencegahannya, pemanfaatan serai wangi sebagai alternatif pencegahan demam berdarah dalam bentuk lilin, teknik pembuatan lilin anti nyamuk. Kegiatan ini diharapkan dapat membantu pemerintah dan masyarakat desa Tumbang Nusa Kabupaten Pulang Pisau dalam penanganan penyakit demam berdarah. Selain itu, kegiatan ini diharapkan dapat meningkatkan kesadaran masyarakat tentang kesehatan dalam mencegah penyakit deman berdarah. Kata kunci: sosialisasi, demam berdarah, serai wangi, lilin anti nyamuk, minyak atsiri ABSTRACT Dengue fever disease is a public health problem in Indonesia, especially during the rainy season. This disease is transmitted by the dengue virus through Aedes aegypti mosquito. Central Kalimantan is the top three in terms of dengue fever disease. Meanwhile, there are Kalimantan natural products which can be used as repellent to prevent the mosquito, such as extracts from lemongrass (Cymbopogon citratus) or citronella grass (Cymbopogon nardus). Mostly lemongrass is used as a kitchen spice, while citronella grass is not very used generally. Furthermore, the utilization of mosquito repellent candles from citronella extract could be a solution to overcome dengue fever disesase. The method used in this socialization is in the form of lectures and distribution of mosquito repellent candle samples. While the lecture material that was socialized was about the dangers of dengue fever, its prevention, the use of citronella grass as an alternative to dengue fever prevention in the form of candles, and preparation of mosquito repellent candles. This socialization is expected to supports the government and the community of Tumbang Nusa village, Pulang Pisau Regency to overcome the dengue fever disease. In addition, this activity is expected to increase public awareness about health in preventing dengue fever. Keywords: socialization, dengue fever, citronella grass, mosquito repellent candle, essential oil

Abstract

Most of the microbes inhabiting the oral cavities are harmless but can cause disturbance and discomfort if the microbial population increases significantly. One of the oral disorders that is often experienced by children, is dental caries. Dental caries is causedby various factors, including eating and brushing habits. The people of Central Kalimantan who live in the watershed use peat water in their daily activities, including for gargling and brushing their teeth. The acidic characteristics of peat water and the high content of organic substances trigger the development of microbes that cause dental caries.This study used dental caries swab samples of patients who rinsed their mouths with peat water. Bacteria were identified molecularly with 16SrRNA markers with primers 63F and 1387R. The similarity of nucleotide sequences was analyzed with BLAST on GeneBank. A phylogenetic tree was built with Maximum Likelihood. Both isolates have a fairly high level of similarity to Klebsiella pneumoniae, namely 91% and 93%. Both isolates are in the same clade, Klebsiella spp., and are close to various commonly found bacteria in the oral cavity, such as Streptococcus mutans and Lactobacillus salivarius.

Abstract

Candidiasis is a fungal infection due to a decrease in the immune system caused by Candida spp. In general, candidiasis is treated with antifungal drugs, but uncontrolled use can result in the emergence of drug resistance and toxicity. Endophytic bacteria have the potential to be biological control agents against various fungal infections including candidiasis. This study aims to determine the antagonistic activity of endophytic bacteria isolated from Dayak onions and the antifungal activity of its cell-free supernatant (CFS) against Candida albicans. Thirteen isolate strains of endophytic bacteria were used in this study. Antagonistic activity was tested using the agar plug diffusion method. Endophytic bacteria that showed antagonistic activity against C. albicans were cultivated in Nutrient Broth media to produce CFS. The antifungal activity of CFS was tested using the Kirby–Bauer disk diffusion method. The results indicated that six isolates of endophytic bacteria from dayak onions have antagonistic activity against C. albicans. CFS from strain CED4 has a strong antifungal activity against C. albicans with a clear zone diameter of 18.5 mm. Further studies are needed to determine the antifungal compounds produced by CED4 isolates for the development of anticandidal.
