Abstract

Insects represent one of the most diverse groups of organisms, and many species act as destructive pests in rice ecosystems. However, the diversity of insect pests in Umbu Wangu Village has not been documented despite recurring yield losses reported by farmers. This study aimed to identify the insect pests associated with rice plants and to develop an electronic atlas (e-atlas) as a digital learning medium for the Entomology course. The research followed a Research and Development design using the ADDIE model, with field surveys carried out in rice fields of Umbu Wangu Village. Insect specimens were collected through direct capture and subsequently identified based on morphological characteristics. The results recorded seven pest species belonging to three orders: Hemiptera, Lepidoptera, and Orthoptera. To complement these findings, an e-atlas was designed as an instructional tool. Expert validation of the e-atlas yielded an average score of 85.5%, which falls into the “very valid” category, indicating strong feasibility for educational use. The documentation of pest diversity provides essential baseline data for local rice protection strategies. At the same time, the validated e-atlas offers an innovative medium that supports student-centered learning in entomology and bridges research outcomes with educational practice.

Abstract

Biology education, particularly in the topic of biodiversity, faces challenges in improving student learning outcomes. One effective approach is problem-based learning (PBL), which promotes active student involvement in solving real-world problems. This study examines the impact of PBL on Student Learning Outcomes in biodiversity at the high school level. A quasi-experimental design was conducted at SMA Negeri 5, involving two classes selected through purposive sampling: an experimental class using PBL and a control class taught using conventional methods. Learning outcomes were assessed via pretests, posttests, N-Gain analysis, and ANCOVA. The results showed a significant improvement in the experimental class. The average pretest score for the experimental class was 45.63, while the posttest score increased to 80.1, resulting in an N-Gain of 0.37 (moderate). In contrast, the control class had a pretest score of 45.31 and a posttest score of 75, with an N-Gain of 0.49. Despite the control class showing a slightly higher N-Gain, the PBL model was more effective in improving learning outcomes, with 93.75% of students in the experimental class achieving mastery compared to 65.63% in the control class. ANCOVA results revealed a p-score of 0.002, confirming that PBL significantly enhances student learning outcomes.

Abstract

The utilization of lignocellulosic biomass as an alternative energy source and industrial material is still constrained by the limited availability of efficient cellulase-producing microorganisms. Mahogany forest soil, which contains leaf litter rich in cellulose, has the potential to serve as a habitat for cellulolytic bacteria with unique characteristics. This study aimed to isolate and characterize cellulolytic bacteria from mahogany forest soil in South Central Timor Regency, East Nusa Tenggara. The research employed an exploratory laboratory design with purposive sampling to collect soil samples beneath mahogany leaf litter at a depth of 0–20 cm. Bacterial isolation was conducted using the serial dilution method and cultivation on Carboxy Methyl Cellulose (CMC) medium. Characterization was performed based on colony morphology and Gram staining, while cellulolytic activity was assessed using the Congo Red method. Data were analyzed descriptively and quantitatively through colony counts using the plate count method and the determination of cellulolytic index values. The results revealed two bacterial isolates, namely AT1 (Gram-positive bacillus) and AT2 (Gram-positive coccus). Both isolates were able to produce clear zones, with cellulolytic indices of 1.96 and 1.26 mm, respectively. Isolate AT1 exhibited higher potential as a cellulase-producing bacterium. These findings highlight the potential of local cellulolytic bacteria as a promising source of cellulase enzymes for biotechnological applications.

Abstract

Masalah utama yang dihadapi dalam kompetensi guru adalah kesenjangan kualitas antara guru di daerah perkotaan dan pedesaan. Guru di daerah terpencil seringkali kurang mendapatkan akses terhadap pelatihan dan pengembangan profesional yang memadai dibandingkan dengan rekan-rekan mereka di kota besar. Tujuan dari kegiatan PKM ini adalah untuk meningkatkan keterampilan guru dalam merancang dan mengimplementasikan modul ajar yang inovatif. Pelatihan ini terdiri dari tiga tahap utama yaitu tahap observasi, perencanaan, pelaksanaan terdiri dari sesi pembukaan, teoritis, Praktis, Implementasi dan evaluasi. Hasil dari kegiatan ini menunjukkan peningkatan signifikan dalam kompetensi profesional guru, termasuk peningkatan pengetahuan, keterampilan, dan kepercayaan diri dalam mengadopsi metode pembelajaran yang lebih inovatif. Peserta didik menunjukkan peningkatan keterlibatan dan motivasi belajar, sementara guru menjadi lebih kolaboratif dan berkomitmen terhadap pengembangan profesional berkelanjutan. Keberhasilan kegiatan ini memberikan inspirasi untuk penyebaran praktik baik di komunitas pendidikan yang lebih luas, dengan harapan membawa transformasi positif dalam sistem pendidikan.

Abstract

A professional science teacher is a teacher who not only understands the basics of science but also understands the skills of the scientific process. However, the results of the tracer study show that science process skills (SSP) from Unwira Biology Education graduates is still low. Therefore, the right strategy is needed to create graduates who understand SSP, like practical jigsaw-based cooperative strategies. The purpose of this study was to determine the effect of practical-based jigsaw strategies on the science process skills of biology education students. This research is a quasi-experiment. The sample used was the fourth-semester students of class A and Class B. Class A as a control and class B as an experimental. The results showed that the average score of students' SPS in the experimental class was 90.4 while in the control class was 62.67. After being analyzed using the Independent-Sample t-Test, it showed a significant effect with a value of 0.036. This research concludes that the practical-based jigsaw strategy influences student science process skills.
