Abstract

Pada masa pandemi, pembelajaran secara daring sering menemui banyak kendala baik bagi siswa maupun guru, diantaranya berupa ketiadaan atau tidak memadainya fasilitas gawai, rendahnya pemahaman tentang media digital (Teknologi Informasi dan Komunikasi), dan keterbatasan sinyal. Mayoritas guru mengalami kesulitan untuk mengajar secara daring, karena belum mengerti metode pengajaran yang tepat dan efisien secara online. Mitra pada kegiatan PPM ini adalah guru-guru di SDN 9 Tanjung Batu di Desa Limbang Jaya I. Tujuan kegiatan PPM ini adalah untuk mendampingi dan mengembangkan kompetensi mitra untuk dapat memanfaatkan gawai secara optimal sebagai media pembelajaran, sehingga proses belajar mengajar dapat lebih efektif dan efisien. Metode berupa pelatihan dengan tahapan kegiatan meliputi identifikasi kebutuhan, perancangan dan penyusunan materi pelatihan, transfer materi melalui presentasi dan peragaan (praktek), dan pendampingan implementasi. Pelaksanaan kegiatan dilakukan dengan tatap muka dan juga secara daring, sehingga pelaksanaannya dimulai dari 27 September 2021 sampai 25 Oktober 2021. Program kegiatan dilaksanakan dalam 4 kali kunjungan, dengan pelatihan meliputi: pengenalan gawai sebagai pendukung proses pembelajaran, penggunaan WhatsApp, google form, pembuatan folder dan direktori, penggunaan zoom, Microsoft Excel, dan pembuatan slide power point untuk presentasi. Antusias dan motivasi guru sangat tinggi untuk meningkatkan kemampuan mereka terhadap pemanfaatan gawai dalam proses pembelajaran. Setelah pelatihan ini, diharapkan guru-guru dapat menerapkannya dalam sistem di sekolah baik dalam hal administrasi, pembelajaran serta pengolahan nilai siswa.

Abstract

Cervical cancer ranks second of cancer that affects women in the world and the first order for women in developing countries. Plant Salung (Psychotria viridiflora Reinw. Ex. Blume) have been used for generations to treat various diseases. The purpose of the study to determine the effects of leaf extracts and fractions salung as the anti-proliferation and inducer of apoptosis in HeLa cervical cancer cells. Concentration of extracts and fractions of 640; 320; 160; 80; 40 µg/mL, while cisplatin using a concentration of 200; 100; 50; 25 µg/mL. The results showed IC50 extract value 380.7 µg/mL. n-hexane fraction amounted to 229.3 µg/mL. ethyl acetate fraction of 116.8 µg/mL, and amounted to 562.8 µg/mL fraksi methanol water, so that the ethyl acetate fraction had enough categories active cytotoxic activity seen from the IC50. To further test the researchers only tested the active fraction is the fraction of ethyl acetate. Results ethyl acetate fraction doubling time is 58, which means replicating or proliferating cells on hour to 58 while the cells replicate cisplatin on the hour to 64.5 and the control cell on the hour to 41. Results of flowcytometry showed ethyl acetate fraction induce apoptosis by 72.82% while cisplatin 87.96%. It can be concluded that the extracts and fractions of leaves salung have a cytotoxic effect, acts as an anti-proliferation and inducer of apoptosis in HeLa cervical cancer cell.

Abstract

Water conservation areas are also known as fisheries reserves or reserves. Lebung Karangan is a fishery reserve in Ogan Ilir, South Sumatra. Community activities, either directly or indirectly, will produce waste in the form of organic and inorganic waste. This study aims to analyze the water quality status, and to identify the types of pesticides in Lebung  Karangan reserve. The study was conducted in the Lebung Karangan reserve, located in Sejaro Sakti Village, Indralaya, Ogan Ilir, South Sumatra, in November 2019. The sampling location was carried out at 4 (four) stations based on considerations of conditions at the research location. Analysis of water quality parameters was carried out in situ and ex situ. The data obtained from water quality measurements were calculated using the Pollution Index (IP) method to determine the status of water quality. The results showed that the water quality status of the Lebung Karangan reserve was in a moderately polluted to heavily pollute state, with an IP value of 10-13,54. The Lebung Karangan reserve was identified as containing organochlorine pesticides. The results of this study are expected to be used as a reference for the government in order to make policies in managing the Lebung Karangan reservae considering the condition of the waters being lightly polluted and the discovery of pesticide compounds. Key words : Lebung Karangan, organochlorine pesticides, reserve, quality status

Abstract

Endophytic fungi isolated from medicinal plants have high diversity and the secondary metabolites produced have biological activity. Endophytic fungi isolated from medicinal plants have been the subject of many studies on their diversity and biological activity, one of which is jambu mawar (Syzygium jambos (L.) Alston). S. jambos has long been used as a traditional medicine to treat infections caused by pathogenic bacteria in many parts of the world, including South Sumatra. This study purposed to explore the diversity of endophytic fungi isolated from the branches of S. jambos, the antibacterial activity of endophytic fungi extracts, the determination of the structure of the compounds, and the activity of the active compounds of the selected endophytic fungi. Observations of the morphological characteristics of endophytic fungi were macroscopically and microscopically. The endophytic fungal extracts were then tested for antimicrobial activity against test bacteria Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, and Escherichia coli using the Kirby-Bauer paper disk diffusion method. Isolation of pure compounds using a gravity chromatography column, the determination of the structure of the compound is determined based on 1H-NMR, 13C-NMR, HMQC, and HMBC spectroscopy. Four endophytic fungi, code SJC1–4, were isolated from a branch of S. jambos. The results of macroscopic and microscopic morphological characterization showed three genera of Botryosphaeria, Trichothecium, and Aspergillus. The endophytic fungal isolate SJC1 exhibited strong activity against Gram-positive bacteria and moderate activity against Gram-negative bacteria, while SJC2–4 showed moderate activity against the four bacteria. Molecular identification of SJC1 revealed that it was Botryosphaeria mamane. Isolation of SJC1’s pure compound yielded compound 1, which was identified as 5-acetyl-6-hydroxy-3-methyl-2H-pyran-2-one. This compound is thought to have antibacterial properties.
