Abstract

This study aims to describe the diversity of seagrass species found on the coast of Malanggo Pesisir Village, South Tinombo District, Parigi Moutong Regency. This study used a quantitative descriptive method with a linear quadratic transect technique conducted at three observation stations. Each station was observed to determine the type and number of seagrass individuals found. The data obtained were then analyzed using the Shannon-Wiener diversity index (H’) to determine the level of seagrass species diversity at the study site. The results showed that there were five seagrass species found, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia, Halodule uninervis, and Cymodocea rotundata. The total number of seagrass individuals obtained was 8,548 with a diversity index value (H’) of 1.518 which is classified as moderate. This value indicates that the seagrass ecosystem in the waters of Malanggo Pesisir Village is in a relatively stable condition and is able to support the existence of several seagrass species. However, human activities around the coastal area have the potential to put pressure on the balance of the seagrass ecosystem. Therefore, efforts are needed to manage and preserve seagrass ecosystems sustainably so that their ecological function is maintained.

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 level of difficulty of students in the subject of biological diversity biology in class X of MAS Al-Ikhlas Karya Mukti and describe the factors that cause students' learning difficulties in the subject of biological diversity biology. This study uses a descriptive method with a qualitative approach. The subjects of this study consisted of 40 students in class X. The types and sources of data used are primary, namely the results of interviews and questionnaires, and secondary data in the form of curriculum documents such as Learning Implementation Plans (RPP). Data analysis is carried out by data reduction techniques, data presentation, and drawing conclusions. The results of the study showed that (1) the average level of student learning difficulty in biodiversity materials reached 65%, which was included in the high category. (2) Internal factors such as the physical and psychological condition of students (70%) in the high category, interest and motivation in learning (75%) in the high category, and cognitive ability (63%) in the medium category. (3) External factors such as the learning environment at school (69%) in the high category, family support (63%) in the medium category, peer influence (61%) in the medium learning difficulty category, and limited learning resources (54%) in the medium category. Thus, it can be concluded that the level of student learning difficulties in biodiversity materials in class X of MAS Al-Ikhlas Karya Mukti shows that students experience high learning difficulties influenced by a combination of internal and external factors.

Abstract

This study aims to determine the effect of Problem Based Learning (PBL) learning model on students' biology problem solving skills in class VIII SMP Negeri 19 Palu. The method used was a quasi-experiment with Non equivalent (Pretest and Posttest) Control Group Design. The research sample amounted to 46 students, consisting of 23 experimental class students who used the PBL model and 23 control class students who used the conventional learning model. Data were collected through observation, teacher and student activity assessment sheets, and tests in the form of valid and reliable description questions. Data analysis was carried out with prerequisite tests, namely normality test and homogeneity test, as well as hypothesis testing using Independent Sample t-test. The results showed that there was a significant effect of PBL model on students' biological problem solving ability. The average posttest score of the experimental class reached 91.73, while the control class was only 75.21. The t-test shows a p value <0.05, which means that the alternative hypothesis is accepted, indicating that the application of the PBL model has a positive effect. Thus, it can be concluded that the PBL model is effective and influential on students' biology problem solving skills in science subjects of class VIII-D SMP Negeri 19 Palu.

Abstract

This study aims to determine the effect of Rosella flower extract (Hibiscus sabdariffa L.) on uric acid levels in White Rats (Rattus norvegicus) induced by LDL. The research method used is the Laboratory experiment method with a Completely Randomized Design (CRD) pattern. The number of samples used was 21 White Rats consisting of 7 treatment groups and 3 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 allopurinol, and the group given LDL induction for 30 days and Rosella flower extract, namely concentrations of 25% (PI), 50% (PII), 75% (PIII), and 100% (PIV) for 14 days. The data obtained were tabulated and analyzed using one-way ANOVA statistical test using SPSS version-30. The results showed that Rosella flower extract had a significant effect (p <0.05) on reducing uric acid levels. The effective concentration for reducing uric acid levels is a concentration of 50% (PII) compared to concentrations of 75% and 100% because there are chemical compounds that are antagonistic to the active compound, thus reducing the extract's ability to reduce blood uric acid levels. The results of the Rosella flower study can reduce uric acid levels so that it can be used as an alternative natural treatment.

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.
