Abstract

The study of bay leaf extract had been done to know its potential as Culex quinquefasciatus repellent. Bay leaf extract has the secondary metabolite compounds, such as terpenoid that is known as repellent of mosquitoes. The aim of this study was to determine the effect of bay leaf extract on Culex quinquefasciatus. The method used in this study was an experiment with complete randomized design which was consisted of six treatments and four repetitions. The treatment consisted of control (0%), P1 (10%), P2 (20%), P3 (30%), P4 (40%), and P5 (50%) of bay leaf extract. Data were analyzed by using one-way ANOVA. The results of this study showed the lowest mean of C. quinquefasciatus which repelled was 83% and the highest was 95,5%. Analysis of variance indicated that amount of C. quinquefasciatus which avoided bay leaf extract was significantly different. Based on the result, it can be concluded that bay leaf extract is potential as C. quinquefasciatus repellent.

Abstract

This study aims to determine the effect of Problem Based Learning supported by pedagogical agents (PBL-PA) on Higher Order Thinking Skills (HOTS) of preservice teachers in Invertebrate Zoology Learning. This study uses a quantitative approach applied to 77 preservice teacher participating in the Invertebrate Zoology lecture in Biology Education, FKIP, Universitas Sriwijaya in Academic Year 2018/2019. The method used is Quasi Experimental with Nonequivalent Control Group Design. Determination of the sample through Simple Random Sampling so that PBL-AP (26 people), PBL (26 people), and traditional classes (25 people). HOTS ability is measured through pretest and posttest with 25 multiple choice questions that have been tested for validity and reliability. Hypothesis testing using Analysis of Covariance (ANCOVA) uses the SPSS 23 program. The results of the study indicate that the PBL-PA Methos has a significant effectiveness on the HOTS ability of preservice teacher. Furthermore, the PBL-PA is better than the PBL and traditional method in improving HOTS ability of preservice teacher. The PBL-PA Mothod can increase learning motivation and make students confident in formulating problems well in the early syntax of PBL.

Penentuan sampel dengan cara Simple Random Sampling sehingga diperoleh kelas PBL didukung agen pedagogi (26 orang), kelas PBL (26 orang), dan kelas tradisional (25 orang). Kemampuan HOTS diukur melalui pre-test dan post-test dengan instrumen 25 soal pilihan ganda yang telah teruji validitas dan reliabilitanya. Uji hipotesis menggunakan Analysis of Covariance (ANCOVA) menggunakan program SPSS 23. Hasil penelitian menunjukkan bahwa Model PBL-AP memiliki pengaruh yang signifikan terhadap kemampuan HOTS mahasiswa calon guru. Selanjutnya, model PBL-AP lebih baik dari pada model PBL dan tradisional dalam meningkatkan kemampuan HOTS mahasiswa calon guru. Model PBL-AP dapat meningkatkan motivasi belajar dan membuat peserta didik percaya diri dalam merumuskan permasalahan dengan baik pada tahap awal sintaks PBL.

Abstract

Penelitian ini bertujuan untuk menganalisis variasi morfometri siput gonggong (Strombus turturella) yang berasal dari dua lokasi berbeda, yaitu Pulau Bangka (Teluk Kelabat) dan Pulau Dompak (Kepulauan Riau), serta mengkaji kontribusinya terhadap peningkatan literasi numerasi dalam pembelajaran biologi di tingkat SMA. Penelitian dilakukan dengan pendekatan deskriptif kuantitatif melalui pengukuran tujuh parameter morfometrik, yaitu panjang cangkang, panjang dasar cangkang, panjang apertura, lebar cangkang, lebar body whorls, lebar apertura,dan tinggi menara. Hasil penelitian menunjukkan bahwa terdapat perbedaan signifikan antara karakter morfometrik siput gonggong dari kedua lokasi. Siput gonggong asal Pulau Dompak memiliki ukuran yang lebih besar dan pola pertumbuhan yang cenderung alometrik positif, sedangkan siput dari Pulau Bangka menunjukkan pola alometrik negatif. Faktor lingkungan seperti jenis substrat dan ketersediaan makanan diduga menjadi penyebab utama perbedaan tersebut.

Abstract

Penelitian ini bertujuan untuk mengetahui pola pertumbuhan ikan sepat siam (Trichopodus pectoralis) dari tiga sungai di Provinsi Sumatera Selatan, yaitu Sungai Kelekar, Ogan, dan Komering. Penelitian dilakukan pada bulan November 2024 sampai dengan Juni 2025 dengan menggunakan metode deskriptif kuantitatif. Sebanyak 120 ekor ikan berhasil ditangkap dengan menggunakan jaring insang dan bubu. Data yang dikumpulkan berupa panjang dan berat ikan, kemudian dianalisis menggunakan Model Alometrik Linier (LAM) untuk mengetahui tipe pertumbuhan. Hasil penelitian menunjukkan bahwa ikan yang berasal dari Sungai Komering mengalami pertumbuhan isometrik, sedangkan ikan yang berasal dari Sungai Kelekar dan Ogan menunjukkan pertumbuhan alometrik negatif dan positif. Nilai koefisien determinasi (R²) hubungan antara panjang dan berat ikan berkisar antara 0,788 sampai dengan 0,933. Perbedaan pola pertumbuhan ini diduga dipengaruhi oleh perbedaan kondisi lingkungan pada masing-masing sungai. Hasil penelitian ini menunjukkan bahwa ikan sepat siam memiliki pola pertumbuhan yang bervariasi pada setiap lokasi, yang mencerminkan adanya bentuk adaptasi terhadap habitat perairan setempat.

Abstract

The results of an interview with a science teacher in Ogan Ilir district that science teachers mastered the skills of various learning models including direct learning models. Some of the junior high school science materials are declarative or procedural. Material that is declarative or procedural requires skills that are carried out in stages of the entire series of activities displayed. The purpose of this community service activity (CSA) is to improve the ability of junior high school science teachers to master the direct teaching model, compile a direct teaching model rpp and be able to implement the direct teaching model in the classroom. The implementation of the activity is carried out in several stages, namely: 1. The preparatory stage, namely field observations and interviews with teachers, reading references to direct learning model materials, holding discussions with PPM team members, preparing training materials in the form of Power Point, approaching school staff and teachers and coordinating related parties. 2. Implementation stage, namely direct training with training methods, demonstrations and discussions and visualizations. Through CSA activities, science teachers from the Ogan Ilir MGMP groups can compile or modify direct learning models with a scientific approach. MGMP science teachers have been able to make 5 aspects of learning implementation planning (LIP), namely listing: learning indicators and objectives, organizing materials, media and learning resources, learning activity steps, and evaluating learning outcomes. Therefore, the RPP format made by mgmp science teachers in Ogan Ilir district was declared feasible. This is evident from the assessment results with all 100 values. After attending the CSA training material, participants enjoyed the material presented, felt that this material was very necessary and felt that their knowledge increased
