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.Â Â

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. .

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. Keywords: Antihyperglycemic, Sambung Nyawa Leaves, Glucose Monohydrate Abstrak Hiperglikemia merupakan kondisi peningkatan gula darah yang cukup signifikan yang akan berubah menjadi kondisi diabetes mellitus.

Penelitian ini bertujuan mengetahui kandungan metabolit sekunder pada infusa daun sambung nyawa dan aktivitas antihiperglikemia pada mencit jantan. Penelitian ini terdiri dari skrining fitokimia dan antihiperglikemia menggunakan metode toleransi yang dinduksi glukosa monohidrat dengan dosis 2g/kgBB. Kelompok uji terdiri dari kelompok kontrol negatif (Na CMC 1%), positif (Glibenklamid), dan 3 kelompok infusa daun sembung nyawa (5%, 10%, 15%). Hasil penelitian menunjukkan infusa daun sambung nyawa mengandung metabolit sekunder yaitu tanin, fenolik, flavonoid dan saponin. Efek penurunan kadar gula darah pada hewan uji menunjukkan penurunan yang signifikan (0,00<0,05) pada infusa konsentrasi 10% dibandingkan dengan kontrol negatif dan tidak signifikan terhadap kontrol positif. Kesimpulan menunjukkan bahwa infusa daun sambung nyawa mempunyai efek antihiperglikemia. Kata Kunci: Antihiperglikemia, Daun Sambung Nyawa, Glukosa Monohidrat

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.
