Abstract

Rice weeds are one of the pest organisms that can reduce production yields.rice because own allelophaty which are parasitic and kill plants directly.The existence of weeds has received little attention from the community in Tahoa Village, even though their existence can damage rice plants (Oryza sativa L.). Purpose of this research can provides information related to the diversity of weed types and their evenness in ricecultivation in Tahoa Village, Kolaka. Sampling was carried out bymaking a plot size of 1 mx 1 m as many as 27 plots divided into 3 stations. The data obtained will be analyzed descriptively and quantitatively and then displayed in the form of tables anddocumentation. Based on the results of the study in Tahoa Village, Kolaka District, Kolaka Regency, 6 families, 8 genera and 8 species were found, namely Digitalia ciliaris, Cynodondactylon, Paspalum scropiculatum L, Alternanthera sessilis L, Sphenoclea zeylanica Geartn., Oldenlandia corymbosaL, Ludwigia octovalvis And Fimbristylis miliacea L. Based on the research results, the most species found were Sphenoclea zeylanica Geartn.. The diversity index (H') of the three stations, namely H'(1.62) states that the diversity of the research location is classified as moderate. The evenness index (E) of the three stations, namely E (0.78) states that the weed evenness index at the research location is classified as high. This is because these weeds have high adaptability to environmental changes both in drought and rain conditions. However, further study is needed regarding the physiology of the weeds found to obtain information regarding their parasitic nature on rice plants.

Abstract

Salah satu permasalahan yang sering ditemukan dalam pelaksanaan pembelajaran bagi anak-anak TKI di ICC Ladang Kosma, Malaysia adalah rendahnya minat dan hasil belajar siswa yang disebabkan kurang akses dan pelayanan pendidikan. Melalui Program MBKM Nasional dalam bentuk “Program Proyek Kemanusiaan” maka Perguruan Tinggi (MRPTNI) mengirimkan mahasiswa ke wilayah tersebut untuk membantu proses pembelajaran dan mendampingi anak-anak TKI. Salah satu pendekatan yang relevan untuk pembelajaran anak-anak tersebut adalah model kooperatif Student Teams Achievement Division (STAD) berbantu media Google Lens yangdiharapkan dapat meningkatkan minat dan hasil belajar IPA pada anak-anak TKI di Malaysia, khususnya di ICC Ladang Kosma. Kegiatan PkM ini dilaksanakan mulai tanggal 27 November 2024 – 22 Februari 2025 dengan prosedur pelaksanaan yang meliputi: desain dan perancangan program, implementasi di lapangan, analisis hasil dan evaluasi kegiatan. Hasil pengabdian menunjukkan bahwa penerapan model pembelajaran kooperatif tipe STAD dengan media Google Lens memiliki dampak yang sangat positif terhadap peningkatan minat (skor rata-rata 90,83 kategori sangat tinggi) dan hasil belajar siswa (97,14 kategori sangat tinggi) pada materi Keragaman Hayati. Sehingga dapat disimpulkan bahwa penerapan model STAD berbasis Google Lens sangat efektif dalam meningkatkan minat dan hasil belajar IPA pada anak-anak TKI ICC Ladang Kosma, Pahang di Malaysia.

Abstract

Edible mushrooms are used as a food source because they are low in fat, high in protein, and rich in vitamins. In addition to being a food source, mushrooms are known to have potential as immunomodulators for various diseases such as cancer, tumors, HIV, tuberculosis, and others. The substances in mushrooms that have potential as antitumor and immunomodulatory agents are polysaccharides. These polysaccharides possess immune-stimulating, anti-tumor, antioxidant, antibacterial, and antiviral activities. One example of an edible mushrooms is  gerigit mushroom (Schizophyllum commune). Until now, the research on Schizophyllum commune is still limited, especially regarding the quantitative determination of the amount of polysaccharides. This study aims to determine the total amount of polysaccharides in Schizophyllum commune from central Thailand using phenol-sulfuric acid and freeze-drying methods. Total polysaccharide concentration data were analyzed using absorbance data obtained from measurements of blank and standard samples on a spectrophotometer and analyzed using microsoft excel software. The results of this study indicate the presence of polysaccharides in Schizophyllum commune, which are characterized by the presence of orange color in the sample when phenol and sulfuric acid solutions are mixed. While for the concentration of total polysaccharides in the Schizophyllum commune samples FD1, FD2 and FD3 obtained consecutive results 42.5256 mg/g 33.7002 mg/g 36.6327 mg/g with an average of 37.62 mg/g. This study shows that gerigit mushrooms have potential as a source of bioactive compounds in the form of polysaccharides that can be used in the health sector
