Abstract

This study aims to determine the effect of rosella flower extract on reducing blood glucose levels in alloxan-induced white rats. The research method used is an experiment conducted in the laboratory with a complete randomized design (RAL) pattern. The number of samples used was 24 white rats consisting of 6 treatment groups and 4 replicates. Normal control group (Kn) is a group that is only given food and drink, negative control group      (K-) is a group given alloxan induction, positive control group (K+) is a group given alloxan induction and metformin synthesized drug, treatment groups I, II, and III are groups given alloxan induction and rosella flower extract at a dose of 50 mg/kg BB, 100 mg/kg BB and 150 mg/kg BB. The data obtained were analyzed by ANOVA statistical test. The results showed that rosella flower extract had an effect on reducing blood glucose levels in white rats induced by alloxan. The most effective dose in reducing blood glucose levels in white rats is a dose of 150 mg/kg.

Abstract

Rhizophora mucronata L. merupakan salah satu jenis mangrove yang mendominasi wilayah pesisir. Meskipun buahnya melimpah, masyarakat setempat masih kurang memanfaatkannya. Padahal, buah mangrove Rhizophora mucronata L. mengandung senyawa metabolit sekunder seperti flavonoid, saponin, dan tanin yang bersifat antibakteri dan antivirus sehingga berpotensi digunakan sebagai bahan pengawet alami. Penelitian ini bertujuan untuk mengetahui pengaruh maserat buah mangrove Rhizophora mucronata L. terhadap daya simpan ikan mujair (Oreochoromis mossambicus) serta menghasilkan media pembelajaran dalam bentuk poster. Penelitian ini merupakan penelitian eksperimen menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan (0%, 10%, 20%, 30%, 40%) dan empat ulangan. Hasil Penelitian ini menunjukkan perlakuan konsentrasi terbaik terdapat pada konsentrasi 40% dengan lama penyimpanan 24 jam. Pengembangan hasil penelitian berupa poster sebagai media pembelajaran memperoleh persentase sebesar 82,2% dan dinilai sangat layak digunakan sebagai media pembelajaran.

Abstract

This study aims to describe and compare the anatomical structure of mangrove leaves of Avicennia lanata Ridl. and Sonneratia alba J.E. Smith in the coastal area of Central Siney Village, South Tinombo District, Parigi Moutong Regency. This study used a quantitative descriptive approach and was conducted at the Biology Education Laboratory, Faculty of Teacher Training and Education, Tadulako University in November 2024. The research samples were A. lanata and S. alba mangrove leaves collected from the research location, with data obtained through microscopic observation, documentation, and questionnaires. The results showed that there were differences in the anatomical structure of the leaves of the two mangrove species, especially in the type of stomata, the thickness of mesophyll tissue, and the development of salt glands. Avicennia lanata has actinocytic stomata and more developed salt glands, while Sonneratia alba has cyclic stomata and thicker pole tissue. Both have similar basic leaf structures, such as cuticle, epidermis, cortex, and xylem and phloem transport tissues. Thus, there are distinctive anatomical adaptations in each species, reflecting survival strategies in the mangrove ecosystem.

Abstract

This study aims to determine the effect of Roselle flower extract (Hibiscus sabdariffa L.) on cholesterol levels in White Rats (Rattus norvegicus) induced by LDL. The research method used is a Laboratory experimental method with a Completely Randomized Design (CRD) pattern. The number of samples used was 24 White Rats consisting of 6 treatment groups and 4 replications. The normal control group (KN) is a group that is only given food and drink, the negative control group (K-) is given LDL induction for 30 days, the positive control group (K+) is given LDL induction for 30 days and simvastatin, groups PI, PII and PIII are given LDL induction for 30 days and Roselle flower extract doses of 50 mg/kg BW, 100 mg/kg BW and 150 mg/kg BW for 21 days. The data obtained were tabulated and analyzed by the one-way ANOVA statistical test using SPSS version-30. The results showed that Roselle flower extract positively contains bioactive compounds such as flavonoids and tannins and has a significant effect (p<0.05) on reducing cholesterol levels in White Rats induced by LDL. The effective dose to reduce cholesterol levels is a dose of 100 mg/kg BW and 150 mg/kg BW.

Abstract

This study aims to inventory the types of macroalgae found in the hot springs of Marana Village, Sindue District, Donggala Regency. This research used descriptive quantitative method with free collection sampling technique. Sampling was carried out directly at five points of hot springs around the research location. Observation data were analyzed descriptively and identified using the determination key and the help of taxonomic images. The results showed that there were five types of macroalgae classified into three classes, namely Chlorophyta, Phaeophyta, and Cyanobacteria. Chlorophyta class (green macroalgae) consists of three species, namely Ulva lactuca, Cladophora glomerata, and Spirogyra sp. Phaeophyta class (brown macroalgae) consists of only one species, namely Saccharina latissima. The Cyanobacteria class (blue-green macroalgae) consists of one species, namely Noctos sp. The existence of these types of macroalgae indicates the existence of biodiversity that can be utilized as a source of environment-based learning and as basic information for further research in the field of aquatic ecology.

Abstract

This study aims to identify the types of medicinal plants, parts of medicinal plants and the processing of medicinal plants used by the Kaili Tribe in Sipi Village, Sirenja District, Donggala Regency, Central Sulawesi. The type of research used in this study is descriptive qualitative with the snowball sampling method. The sampling technique used the roaming method and free collection. The method of determining the sampling area using the roaming method of the research location, namely, explored from the initial boundary of hamlet 1 in the west to the boundary of hamlet 4 in the east in Sipi Village. Data were collected through field observations, free interviews with people who have local knowledge about medicinal plants, and direct documentation. The results showed that there are 20 species of medicinal plants from 12 families that are used to treat various diseases such as diabetes, external wounds, tinea versicolor, toothache, digestive disorders, and others. The plant parts used include roots/rhizomes, stems, leaves and sap. The methods of utilization are various such as boiling, pounding, rubbing, chewing and drops. This research shows the importance of preserving traditional knowledge regarding the use of medicinal plants by local communities as part of local wisdom that is passed down from generation to generation.
