Abstract

Penelitian ini bertujuan menjelaskan realisasi fungsi tutur dan pola gramatikal teks percakapan pada buku teks bahasa Inggris dan menjelaskan kesesuaian antara jenis ungkapan dalam teks percakapan dengan fungsi kebahasaan yang terdapat dalam kompetensi dasar dari kurikulum. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan menggunakan bentuk analisis fungsional dan struktural yang dikembangkan oleh Eggins dan Slade (1997). Hasil penelitian ini menunjukkan bahwa terdapat 253 fungsi tutur yang terealisasi dalam teks percakapan yaitu terdapat 75 (29.65%) fungsi pembuka percakapan, 90 (35.57) fungsi pelanjutan percakapan, dan 88 (34.78%) fungsi merespon pembuka percakapan. Selain itu, terdapat 278 jenis mood yang terdiri dari 148 (53%) bentuk deklaratif lengkap, 40 (14%) deklaratif tidak lengkap, 18 (6.5%) polar interogatif, 24 (8.5%) wh-interogatif, 8 (4%) imperatif, 6 (2%) eklamatif, dan 34 (12%) jenis klausa minor. Hasil penelitian ini juga menunjukkan bahwa terdapat 21 (87%) dari 24 jenis ungkapan dalam kompetensi dasar dan sebaliknya ada 3 (13%) jenis ungkapan yang tidak terdapat di dalam teks percakapan pada buku teks.This study is aimed at explaining the realization of speech functions and grammatical patterns of conversational texts and the compatibility of some typical expressions with the basic competence of English curriculum. A descriptive qualitative approach by means of functional and structural analysis proposed by Eggins and Slade (1997) is used. The result show that there are 253 speech functions realized in the conversational texts consisting of 75 (29.65%) opening, 90 (35.57%) continuing, and 88 (34.78%) reacting. Additionally, the study show that there are 278 mood types used in the conversational texts. They comprise 148 (53%) declarative full, 40 (14%) elliptical declarative, 18 (6.5%) polar interrogative, 24 (8.5%) wh-interrogative, 8 (4%) imperative, 6 (2%) exclamative, 34 (12%) minor. The study also show that 21 (87%) typical expressions of the 24 total number of language function specified in the basic competence are introduced in the textbook whereas 3 (13%) expressions are not realized in the textbook.

Abstract

One of the plants used by the people of East Kalimantan, especially the people of West Kutai, as a medicinal plant is Kitolod (Hippobroma longiflora L.). The plant parts used are the leaves and flowers. The secondary metabolites contained in Kitolod leaves are alkaloids, saponins, flavonoids and polyphenols. The aim of this research is to identify secondary metabolite groups and test the cytotoxicity of Kitolod leaf extracts and fractions. Secondary metabolites are identified qualitatively using various chemical reagents and metabolites characterized by the presence or absence of color changes or the presence of sediment or foam. Cytotoxicity testing was carried out using the Brine Shrimp Lethality Test (BSLT) method. The data research was analyzed using the Reed and Muench method to determine the Lethality Concentration 50% value. The results of research on the metabolite content of ethanol extract, fractions: n-hexane, ethyl acetate and n-butanol contain alkaloid, flavonoids and phenolic/polyphenols compounds. The bioactivity test results for the ethanol extract had an LC50 value of 592.93 ppm, the n-hexane fractions of 582.77 ppm, the ethyl acetate fraction of 531.37 ppm, and the n-butanol fraction of 119.48 ppm. These results indicate that the n-butanol fraction of Kitolod leaves has stronger cytotoxic activity than other extracts. .

Abstract

Hyperglycemia is a condition where blood sugar increases significantly which can lead to diabetes mellitus. Sambung Nyawa (Gynura Procumbens) leaves are a plant that is empirically believed to reduce hyperglycemia and has been scientifically proven based on several studies, however there has been no research that provides information about sembung nyawa leaves in infusion form. This study aims to determine the content of secondary metabolites in the infusion of the leaves of Gynura Procumbens and its antihyperglycemia activity in male males. This study consisted of phytochemical and antihyperglycemia screening using a tolerance method induced by glucose monohydrate at a dose of 2g/kgBW. The test group consisted of a negative control group (Na CMC 1%), a positif group (Glibenclamide), and 3 groups of sambung nyawa leaf infusion (5%, 10%, 15%). The results of the research showed that the infusion of sembung nyawa leaves contained secondary metabolites, namely tannins, phenolics, flavonoids and saponins. The effect of reducing blood sugar levels in test animals showed a significant reduction (0.00<0.05) at a 10% concentration infusion compared to the negative control and not significant to the positive control. The conclusion shows that the infusion of sambung nyawa leaves has an antihyperglycemic effect.

Abstract

Tabar kedayan (Aristolochia papillifolia Ding Hou.) is an endemic plant from northern Kalimantan and is widely used as traditional medicine by the Dayak people. This study aims to determine the pharmacognostic profile and toxicity data of Tabar Kedayan rootstock. The results showed macroscopically woody stem type, round stem shape, grooved or serrated stem surface, yellow-brown stem color, weak characteristic odor, bitter taste, microscopically found starch grains, calcium oxalate crystals, stone cells, cork cells, tracheids, and wood vessels. Fluorescence analysis under visible and ultraviolet light for Tabar Kedayan rootstock powder with different chemical reagents showed different fluorescence effects. Water content (0.466±0.01%), ethanol content (0.325±0.014%), moisture content (12.40±0.15%), total ash content (1.438±0.15%), and acid insoluble ash content (0.423±0.06%). Phytochemical screening of the chemical compounds of the ethanolic extract showed the presence of alkaloids, terpenoids, saponins, flavonoids, and tannins. The levels of total polyphenols (15.095 ± 1.11 µg GAE/mg sample), total flavonoids (0.184 ± 0.02 µg QE/mg sample), and total alkaloids (0.056 ± 0.02 µg QAE/mg sample) were found. The brine shrimp lethality (BSLT) assay results showed the highest LC50 value by the n-hexane fraction with an LC50 value of 17.660 µg/ml.

Abstract

Keterampilan literasi dan numerasi merupakan kompetensi esensial abad ke-21 yang perlu dimiliki guru dan peserta didik untuk mendukung pembelajaran sains yang bermakna, kontekstual, dan aplikatif. Namun, guru fisika di wilayah Hulu Sungai Selatan masih menghadapi tantangan dalam mengintegrasikan literasi-numerasi ke dalam pembelajaran fisika yang relevan dengan konteks lokal, khususnya lingkungan lahan basah. Kegiatan pengabdian kepada masyarakat ini bertujuan mengoptimalkan kompetensi guru MGMP Fisika Kabupaten Hulu Sungai Selatan dalam merancang dan mengimplementasikan perangkat ajar fisika berbasis literasi-numerasi yang kontekstual. Metode pelaksanaan kegiatan menggunakan pendekatan pelatihan dan pendampingan. Materi meliputi penguatan konsep literasi-numerasi fisika, pemanfaatan fenomena lahan basah sebagai sumber belajar, serta pelatihan penyusunan RPP, LKPD, dan soal kontekstual. Hasil kegiatan menunjukkan peningkatan kapasitas guru dalam memahami dan mengaplikasikan literasi-numerasi ke dalam pembelajaran. Evaluasi respons peserta menunjukkan skor kepuasan rata-rata di atas 4,5 (dari skala 5), mengindikasikan efektivitas program. Kesimpulannya, kegiatan ini berhasil memperkuat kompetensi pedagogis guru dalam menyusun pembelajaran fisika yang kontekstual, kolaboratif, dan relevan dengan karakteristik lokal, serta mendorong terbentuknya budaya literasi-numerasi berbasis lingkungan.
