Abstract

The research is a quasi-experimental that aimed to know the effect of making mind mapping at the end of learning in guided inkuiri learning model toward students’ learning outcome in XI IPA class of SMA Kristen Gamaliel Makassar. The independent variable in this experiment is making mind mapping at the end of lerning with use inquiri learning model. The dependent variable was the students’ learning outcome on the subject matter of reaction rate. The population was XI IPA with 4 classes of SMA Kristen Gamaliel Makassar and sample classes consisted of two classes, namely XI IPA1 class as an experiment class and XI IPA2 class as a control class with 33 students in each classes. Taking technique of sample was a simple random sampling. The research data was gathered by learning outcome test of reaction rate subject matter for post-test which was analyzed by using Mann-Whitney test. The result of hypothesis with Mann-Whitney test was Zcalculated = 1.70 at α = 0.05 obtained Ztable = 1.64. Therefore, Zcalculated > Ztable, which the H1 accepted and H0 rejected. It showed that there is an effect of making mind mapping at the end of learning in guided inkuiri learning model toward students’ learning outcome in XI IPA class of SMA Kristen Gamaliel Makassar on reaction subject matter.

Abstract

A protein can be identified based on each level of its structure. Every protein contains at least primary, secondary and tertiary structures. Only a few proteins have a quaternary structure as well. The primary structure consists of a linear chain of amino acids. One of the electric field-mediated separation methods that is often applied to analyze proteins based on their size is SDS-PAGE electrophoresis. This technique is based on the assumption that after denaturation, the polypeptide chains covered in SDS micelles have comparable surface charge densities, so that the resulting differences in electrical migration are based on their size. SDS-PAGE separates protein molecules based on their particle size and shape. This gel can be made with varying pore sizes which are determined based on the total amount of acrylamide compound added (gel concentration). The gel pore size will become smaller as the gel concentration increases so that only protein molecules that have a small molecular weight can pass through. This measure of the molecular weight of a protein is useful in mapping proteins (protein profiling). The gel staining used is bromophenol blue which functions to color proteins because it binds weakly to proteins. The higher the protein concentration of a sample being electrophoresed, the resulting band will appear clear and thick. However, if the protein concentration of a protein is low, the resulting band will appear thin.

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan senyawa metabolit sekunder dan aktivitas antibakteri ekstrak Lichen Usnea barbata terhadap bakteri Escherichia coli resisten terhadap antibiotik amoxicilin-klavulanat (AMC) dan sulfametoksazol (SXT). Tahap penelitian meliputi ekstraksi dengan metode maserasi menggunakan tiga pelarut yaitu, (n-heksan, kloroform dan aseton), uji fitokimia, dan uji aktivitas antibakteri menggunakan metode difusi cakram menggunakan lima variasi konsentrasi (62,5; 125; 250; 500; dan 1000 ppm), kontrol negatif (kloroform) dan kontrol positif (amoxicilin-klavulanat) yang diulang sebanyak tiga kali. Hasil uji fitokimia menunjukkan bahwa ekstrak aseton mengandung alkaloid, flavonoid, dan saponin; ekstrak kloroform mengandung alkaloid dan flavonoid; sedangkan ekstrak n-heksan mengandung steroid. Hasil uji aktivitas antibakteri menunjukkan bahwa kontrol positif menghasilkan rata-rata diameter zona hambat sebesar 18 mm, sedangkan kontrol negatif tidak menunjukkan zona hambat (0 mm). Ekstrak menunjukkan daya hambat lemah dengan rata-rata zona hambat terbesar ditemukan pada ekstrak kloroform 1000 ppm (4 mm). Berdasarkan hasil tersebut, ekstrak Lichen U. barbata menunjukkan aktivitas antibakteri dengan kategori lemah terhadap E. coli yang resisten terhadap antibiotik.

Abstract

This research is a development research (Research and Development) with the objectives: (1) to assess the quality of the instrument in terms of content validity and empirical validity, (2) to determine the reliability of the developed instrument, and (3) to assess the practicality of the developed instrument. The product developed is a contextual science literacy assessment instrument on the topic of colloids. The developed contextual science literacy instrument is in the form of multiple-choice questions. The research was conducted using the 4D development model, which includes the stages of define, design, develop, and disseminate. The results of rational validation by two expert validators yielded 15 valid test items with an Aiken's index ≥ 0.75. The instrument was tested on 34 students from class XII MIPA 3 of SMAN 1 Gowa. The results of empirical validation using the point biserial formula at α=0.339 yielded 14 valid test items. The results of the reliability test using KR-20 showed that the instrument was categorized as reliable with a value of 0.831. The analysis of the item discrimination power showed that there were 2 very good items, 6 good items, 4 fair items, and 3 poor items. The distribution of the item difficulty level was 47% difficult items, 40% medium items, and 2% easy items. The practicality of the contextual science literacy assessment instrument on the topic of colloids was categorized as practical based on the positive results of the student questionnaire (85%) and the teacher questionnaire (95%).

Abstract

The objective of this research was to develop a model of food chemistry learning process to guide student’s attitude and behaviour on healthy eating pattern and facilitating their academic achievement.  The participants were student who enrolled of food chemistry course. Preliminary results identified 90% of students were enjoy the course’s learning process, and 80% of them argued that the course was very valuable. However, there were 40% among participants experienced teacthing troubles to understand the terms of chemistry reactions, particularly during food processing.  In addition, their knowledge related to food chemistry was not applied to be guidance in choosing everyday food consumption especially during they were in university.As conclusion from the preliminary result, learning’s model is critically needed in order to (1) enhance the student’s knowledge, particularly in the area of reaction of chemistry compound (nutrition value) during food processing and (2) improve of student’s attitude and behaviour in well-selecting of healthy food. Social cognitive Bandura is selected approach to be incorporated with learning process of food chemistry by the following reasons: (1) modelling enabled, (2) self-efficacy, (3) observational learning, and (4) motivation and reinforcement.

Abstract

Abstrak – Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat Kecamatan Pattallasang, Kabupaten Takalar, dalam memanfaatkan bahan alam sebagai obat tradisional. Potensi tanaman obat di wilayah ini cukup melimpah, namun pemanfaatannya masih terbatas dan belum berbasis pengetahuan ilmiah. Program dilaksanakan melalui sosialisasi, pelatihan berbasis ceramah–diskusi–demonstrasi, dan pendampingan praktik pengolahan tanaman obat. Selain itu, digunakan media digital berupa video tutorial dan forum diskusi daring untuk pembelajaran berkelanjutan. Hasil kegiatan menunjukkan peningkatan pemahaman dan keterampilan masyarakat dalam identifikasi dan pengolahan tanaman obat lokal secara aman dan higienis. Evaluasi menunjukkan masyarakat mulai mempraktikkan pengolahan herbal di rumah dan berminat mengembangkan usaha berbasis herbal. Program ini berkontribusi dalam pemberdayaan masyarakat serta mendukung kemandirian kesehatan berbasis potensi lokal.Kata kunci: pengabdian masyarakat, tanaman obat, obat tradisional, Pattallasang, edukasi herbal
