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 describe the effectiveness of the use of biology laboratories on student learning outcomes at SMA Negeri 1 Tikke Raya. This type of research uses a quantitative quasi-experimental design using a pretest and posttest control group design. Quantitative data are in the form of measurement results of student learning outcomes. The population in this study were all 145 students of class X of SMA Negeri 1 Tikke Raya. Sampling used a purposive sampling technique, and the sample in this study was 2 classes consisting of class X1 as the Experimental Class and X2 as the control class. Data collection techniques used observation and tests. The results showed that the use of biology laboratories proved to be more effective in improving the learning outcomes of class X students of SMA Negeri 1 Tikke Raya compared to conventional methods. The results of the analysis showed an increase in both groups, but the experimental group obtained significantly higher post-test scores, indicating that the use of laboratories had a positive effect on biology learning outcomes.

Abstract

This study aims to describe adolescents' perceptions of premarital sex education at SMA Negeri 1 Kasimbar. This research uses a descriptive quantitative research method. The population in this study consisted of 416 students. The sample in this study consisted of 104 students, selected using stratified random sampling from grades X, XI, and XII at SMA Negeri 1 Kasimbar. The research instruments used were observation, interviews, questionnaires, and documentation. The instrument test results were declared valid and reliable. The research results indicate that adolescents' perceptions of premarital sexual education are, overall, in the very good category, with 89 students (85.6%) falling into the very good category, 14 students (13.5%) in the good category, and only 1 student (1.0%) in the sufficient category. The overall average score reached 3.53 on a four-point Likert scale. The aspect of parental role received the highest score with an average of 3.61, followed by attitudes at 3.58, information media at 3.55, school involvement at 3.48, and knowledge at 3.45. Thus, it can be concluded that adolescents are beginning to have a high awareness of the importance of correct and responsible understanding of sexuality. Therefore, sexual education needs to be integrated into Biology lessons at school to strengthen adolescents' knowledge and positive attitudes towards reproductive health.

Abstract

Kesadaran dan pemahaman masyarakat di desa Tanamea akan bahaya dari cemaran mikroplastik masih rendah, yang ditunjukkan dari cara pengolahan sampah oleh masyarakat, yaitu dengan membakar ataupun menguburkan dalam tanah tanpa memisahkan antara sampah plastik dengan sampah lainnya. Kegiatan pengabdian ini bertujuan untuk membangun kesadaran, pemahaman dan literasi masyarakat desa Tanamea akan bahaya mikroplastik bagi kesehatan, agar masyarakat lebih bijak dalam penggunaan produk berbahan plastik, serta melakukan pengolahan sampah plastik dengan benar. Kegiatan PkM ini dilaksanakan di desa Tanamea, Banawa Selatan, dengan jumlah warga selaku partisipan sebanyak 28 orang. Metode pelaksanaan kegiatan PkM ini mengadopsi pendekatan metode PkM Partisipatory Action Research (PAR). Dari kegiatan PkM ini, antusias masyarakat terlihat dari beberapa pertanyaan yang diajukan, meliputi cara mengatasi/mengendalikan cemaran mikroplastik, khsusunya yang masuk pada tubuh manusia, cara mengurangi bahaya penggunaan produk perlengkapan rumah tangga berbahan plastik. Selain itu, masyarakat juga meminta penjelasan terkait cara penanganan sampah plastik yang terdapat di area pesisir pantai desa Tanamea, yang pada dasarnya adalah sampah plastik yang terbawa arus laut. Dari kegiatan pengabdian ini, dapat disimpulkan bahwa perlu adanya upaya berkelanjutan dalam membangun kesadaran masyarakat terkait penanganan sampah plastik

Abstract

Many carbohydrates are produced from the Cassava plant (Manihot esculenta Crantz) and have an essential role for humans. Cassava is used not only as a food source but also as industrial raw material, ethanol, and animal feed. To avoid the rapid deterioration of post-harvest Cassava products, Casava is very potential to be developed into various processed products and industrial raw materials. The development of the snack or snack industry has proliferated, both in type, taste, and packaging. The results of interviews conducted by a service team with the home industry Cake group in Toaya Vunta village showed that many cassava plants still have not been used optimally. This service aims to provide training and mentoring workshops on making Cassava crackers (Cassava crackers) of various flavors to mothers of the home cake industry group in Toaya Vunta village. Through the community service program, the Toaya Vunta village home industry group can be assisted in training and workshops to manufacture more modern Cassava chips with different flavors to improve their knowledge and skills. The method in this activity is to use the method of lectures, demonstrations, discussions, practices, and observations, which are the results of the activities. This activity has three stages: material presentation, direct practical assistance in making cassava chips, and the packaging process. The results of this service can improve the knowledge and skills of the home industry group of mothers in making cassava chips with various flavors. Based on these results, it is hoped that it can improve the family economy as well as support the development of creative economy businesses and community empowerment in Toaya Vunta village
