Abstract

Differentiated learning is the core of the independent curriculum now.The aim of this research is to develop an instrument for measuring the cognitive learning outcomes of high school students based on differentiated learning on elasticity material and to obtainits characteristics. Differentiation, in this case, is differentiation of student learning styles. The instrument grid is arranged based on indicators of cognitive learning outcomes, which are then used to compile question items. The test instrument consists of two test sets, each of which has 9 items including two anchor itemsso that the total number of items is 16 items and has been validated by 6 experts. The validated instrument was tested on 252 respondents spread across high schools in the low, medium and high categories. Dichotomous data were analyzed using the Partial Credit Model (PCM). The trial results showed that all 16 items and the differentiated learning-based student cognitive learning outcomes test instrument were proven to be valid, fit the PCM model, and reliable, which means all items were in the good category. Thus, the test instrument developed meets the requirements for measuring the cognitive learning outcomes of high school students on elasticity material based on differentiated learning.

Abstract

Background: Several students experience difficulties in mastering biological classification concepts. To address this issue, a digital E-Flashcard was developed as an instructional medium that supports technology-integrated learning, enhances motivation and comprehension, and offers flexible and practical use. This study evaluates the validity, practicality, and impact on learning outcomes of the E-Flashcard designed for Tenth-grade students at SMA Negeri 2 Gorontalo. Methodology: This study employed a Research and Development (R&D) method using the ADDIE development model, with a one-group pretest-posttest design involving 20 students from class X4 at SMA Negeri 2 Gorontalo. The instruments used included interview instruments, media and material validation instruments, and pretest and posttest instruments. Findings: The evaluation results indicated that the developed E-Flashcard met high feasibility standards, with material validation reaching 95.33% and media validation achieving 91%, both categorized as very feasible. Practicality assessment showed highly positive responses, reflected by a 98.5% score from teachers and 86% from students, both within the very practical category. Furthermore, analysis of learning improvement based on pretest and posttest scores yielded an N-gain value of 0.55, which falls into the moderate improvement level. These findings confirm that the E-Flashcard media satisfies the criteria of validity and practicality and demonstrates a meaningful improvement in student learning outcomes during limited-scale implementation. Contributions: This research advances digital biology instruction by introducing and empirically validating an ADDIE-based E-Flashcard model that enhances students’ conceptual understanding of biological classification, offering a scalable alternative to conventional printed flashcards in secondary education

Abstract

Penelitian ini dilatarbelakangi oleh hasil observasi di SMA Negeri 7 Gorontalo yang menunjukkan bahwa pembelajaran biologi masih didominasi metode ceramah dan penggunaan LKPD cetak, sehingga siswa cenderung pasif dan lebih berorientasi pada hafalan daripada memahami konsep secara mendalam. Kondisi ini menyebabkan kesulitan dalam memahami materi abstrak, khususnya virus, karena keterbatasan media yang mampu memvisualisasikan konsep mikroskopis dan dinamis. Selain itu, rendahnya keterlibatan siswa berdampak pada kurang berkembangnya kemampuan berpikir kritis dan analitis. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan LKPD berbasis Constructivist Teaching Sequence berbantuan Augmented Reality pada materi virus. Metode yang digunakan adalah Research and Development (R&D) dengan model ADDIE yang meliputi analyze, design, development, implementation, dan evaluation. Penelitian dilakukan pada siswa kelas X SMA Negeri 7 Gorontalo dengan instrumen berupa lembar validasi, angket kebutuhan, observasi keterlaksanaan, serta angket respon guru dan siswa. Hasil menunjukkan LKPD memiliki validitas sangat tinggi dengan nilai 94% (materi) dan 97% (media). Kepraktisan ditunjukkan oleh keterlaksanaan pembelajaran 94,5%, respon guru 93%, dan respon siswa 82% dengan kategori baik. Dengan demikian LKPD yang dikembangkan dinyatakan valid dan praktis serta dapat diuji coba secara luas sebagai bahan ajar dalam pembelajaran materi virus.

Abstract

The purpose of this study was to analyze the lead (Pb) levels in fish for consumption on the East Pentadu Coast, Gorontalo Province, and to evaluate whether these levels were within the maximum limits according to the applicable quality standards. This study was conducted at three locations: the boat dock, the mangrove area, and the auction site. The method used in this study was a quantitative descriptive method using a purposive sampling technique. The population in this study included fish for consumption on the East Pentadu Coast, the muscles of which were collected at all three locations. The results showed that the highest lead levels in Cetoscarus ocellatus fish were 0.0003 mg/kg, far below the maximum limit of SNI 7387:2009, which is 0.1 mg/kg. Therefore, consumption of fish from the East Pentadu Coast is still considered safe, although the cumulative Pb properties still require vigilance.

Abstract

This study aims to determine the effect of endophytic fungal isolates from the leaves of the Chinese Ketepeng (Cassia alata L) plant on the growth of Malessezia furfur and to determine the significant differences of each treatment of endophytic fungal isolates from the leaves of the Chinese Ketepeng (Cassia alata L) plant on the growth of Malessezia furfur. The method in this study used a completely randomized design (CRD) with 4 treatments and 6 replications. The treatments were: JEKA 1 (Chinese Ketepeng Endophytic Fungus 1), JEKA 2 (Chinese Ketepeng Endophytic Fungus 2), Positive Control (Ketoconazole), and Negative Control (Aquadest). The results showed that 2 isolates of endophytic fungi were successfully isolated from the leaves of the Chinese Ketepeng plant. After testing the inhibitory power against the Malassezi furfur fungus, the JEKA 1 isolate obtained an inhibition zone value of 10 mm and the JEKA 2 isolate an inhibitory zone value of 11 mm. The results of the analysis using the Kruskal-Walis test showed that there was an effect of endophytic fungal isolates from the leaves of the Chinese ketepeng plant (Cassia alata L) on the growth of the fungus Malassezia furfur. Then from the results of further tests using Duncan's test, it was found that each treatment, namely the negative control treatment was significantly different from JEKA 1, JEKA 2 and positive control, while there was no significant difference between JEKA 1, JEKA 2 and positive control.

Abstract

The problem of urban waste in Makassar City continues to increase in line with economic growth and the number of businesses, particularly micro, small, and medium enterprises (MSMEs). The low level of knowledge and skills among business actors in environmentally friendly waste management means that waste is not yet being managed optimally and still has the potential to cause negative impacts on the environment. The community service activity aims to provide standards for the implementation of waste reduction and management at the source, based on Presidential Regulation No. 97 of 2017 concerning national policies and strategies for the management of household waste and similar waste, as well as to increase the knowledge, attitudes, and skills of business actors in Makassar City in managing waste in an environmentally friendly manner through socialization and training activities. The methods used to carry out these activities are socialization, training, and discussions on environmentally friendly waste management. The activities were carried out in a participatory manner through material delivery, interactive discussions, and hands-on practice. The results of the activities show an increase in business actors' understanding of the importance of environmentally friendly waste management and their ability to implement waste sorting and management practices at the source. It is hoped that this activity will encourage changes in the behavior of business actors in waste management, reduce the amount of waste sent to final processing sites (landfills), and support the realization of a clean and sustainable environment in the city of Makassar.

Abstract

Kontaminasi mikroba pada cairan rendaman lensa kontak dapat meningkatkan risiko gangguan pada mata. Penelitian ini bertujuan mendeskripsikan karakter fenotipik isolat bakteri terduga Staphylococcus spp. pada cairan rendaman lensa kontak. Penelitian deskriptif ini menggunakan sepuluh sampel cairan rendaman yang diperoleh dari lima pengguna lensa kontak yang memenuhi kriteria inklusi. Setiap sampel diencerkan hingga 10⁻³, ditanam sebanyak 0,1 mL pada Mannitol Salt Agar (MSA), dan diinkubasi pada suhu 37 °C selama 24–48 jam. Satu koloni terpilih dari setiap sampel dimurnikan, kemudian dikarakterisasi berdasarkan morfologi koloni, pewarnaan Gram, dan uji katalase. Sepuluh isolat yang diperoleh berbentuk koloni bulat dengan tepian utuh; enam isolat berwarna kuning dan empat isolat berwarna putih, sedangkan delapan isolat berelevasi timbul dan dua isolat datar. Seluruh isolat menunjukkan reaksi Gram positif dan katalase positif. Kombinasi pertumbuhan pada MSA, karakter kolonial, reaksi Gram, dan hasil uji katalase menunjukkan bahwa isolat tersebut memiliki karakter yang konsisten dengan bakteri terduga Staphylococcus spp. Namun, rangkaian uji masih perlu dilakukan untuk mengonfirmasi identitas hingga tingkat genus atau spesies karena penelitian belum melakukan  uji koagulase, panel biokimia tambahan, spektrometri massa, atau analisis molekuler. Oleh karena itu, temuan ini merupakan deteksi presumtif dan perlu dikonfirmasi menggunakan metode identifikasi yang lebih spesifik. Penelitian lanjutan juga perlu melibatkan sampel yang lebih besar serta kontrol mutu laboratorium yang terdokumentasi.
