Abstract

Ikan merupakan hewan vertebrata aquatis yang bernafas menggunakan insang. Oleh karena itu perubahan  pada ekosistemnya akan mempengaruhi keberadaannya. Perubahan tersebut dapat disebabkan kerusakan lingkungan oleh manusia, sehingga ikan  banyak digunakan sebagai indikator pencemaran. Untuk mengetahui pencemaran  lingkungan di pantai Jeranjang bisa dilihat dari keragaman jenis ikan dari hasil tangkapan nelayan. Namun belum adanya standarisasi ukuran morfometrik  dan  meristik khususnya pada beberapa jenis ikan hasil tangkapan nelayan yang diperlukan  sebagai  dokumentasi dan dasar identifikasi ikan. Penelitian ini bertujuan untuk mengidentifikasi karakter morfometrik ikan hasil tangkapan nelayan di Pantai Jeranjang. Jenis penelitian ini adalah deskriptif eksploratif. Metode penelitian deskriptif eksploratif merupakan metode penelitian yang berusaha mengungkap fakta suatu kejadian, objek, aktivitas, proses dan manusia secara apa adanya pada waktu sekarang atau jangka waktu yang masih memungkinkan dalam ingatan responden, jenis ikan yang didapat atau ditemukan sebanyak 7 spesies, Diketahui bahwa dari 3 nelayan didapatkan 40 ekor ikan yang berbeda jenis. Masing-masing ikan memiliki ukuran dan bentuk tubuh yang berbeda, meski berasal dari Kelas yang sama yakni Actinopterygii. Terdapat perbedaan panjang maupun bentuk dan struktur tubuh untuk setiap karakter morfometrik ikan.

Abstract

Gliricidia leaves are rich in nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth. This makes Gliricidia leaves a potential raw material for liquid organic fertilizer (LOF). Therefore, this study was conducted to determine the optimal dosage of Gliricidia leaf LOF that can be applied to enhance the growth of Green Mustard (Brassica junceaL.). The study used a Completely Randomized Design (CRD) with five treatments. The treatments consisted of a control (P0), 30 ml LOF/liter (P1), 60 ml LOF/liter (P2), 90 ml LOF/liter (P3), and 130 ml LOF/liter (P4). The observed parameters included plant height (cm), number of leaves (leaves), and leaf width (cm) at 7, 14, 21, and 28 days after planting (DAP). The data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test at the 5% level, using SPSS 20 software. The results showed significant effects on plant height, number of leaves, and leaf width between the control and each dosage of Gliricidia leaf LOF. The dosage of 130 ml LOF/liter resulted in the highest average growth in plant height, number of leaves, and leaf width compared to the control and the 30, 60, and 90 ml LOF/liter treatments. Therefore, it is concluded that applying 130 ml of Gliricidia leaf LOF per liter of water is recommended to enhance the growth of Green Mustard.

Abstract

This study investigates the effect of the Project-Based Learning (PjBL) model on students' cognitive learning outcomes, compared with Problem-Based Learning (PBL), in senior high school biology. The research was motivated by persistently low cognitive achievement and teacher-centred practices observed at SMA Negeri 3 Selong, where many Grade X students scored below the minimum mastery criterion and struggled to construct coherent scientific arguments. A quantitative quasi-experimental design with a non-equivalent control group pretest–posttest design was employed. The population consisted of all Grade X students (N = 84), with purposive sampling used to select two intact classes: X-8 as the experimental group (PjBL; n = 21) and X-7 as the control group (PBL; n = 21). The experimental class engaged in an authentic project constructing aquascapes from recycled jars, while the control class followed PBL-based instruction on the same content. Cognitive learning outcomes (C1–C4) were measured using a multiple-choice and an essay test. Assumption checking using the Shapiro–Wilk and Levene's tests indicated that posttest data met the requirements for parametric analysis. An independent-samples t-test on posttest scores revealed a statistically significant difference between groups (p = 0.001), with the PjBL class outperforming the PBL class by an average of 17.476 points. These findings demonstrate that PjBL has a significant and positive impact on students' cognitive learning outcomes in biology and is more effective than PBL in enhancing lower- and middle-order cognitive processes. The study recommends systematic integration of PjBL in science classrooms and further research with larger, multi-site samples, including additional outcome variables such as motivation, critical thinking, and creativity.
