Abstract

This study investigated the effects of bamboo leaf supplementation on nutrition intake, productivity, and growth performance in Boer goats (Capra aegagrus hircus). A randomized complete block design was employed, with four treatment groups: Control (no bamboo leaf supplementation) and three experimental groups receiving Low Dose (50g/day/goat), Medium Dose (100g/day/goat), and High Dose (150g/day/goat) of bamboo leaves. Each treatment group comprised three repetitions. Thirty-six healthy Boer goats of similar age and weight were selected and housed individually with ad libitum access to water and a basal diet. Bamboo leaf supplementation was administered daily for 60 days, following which nutrition intake, productivity, and growth performance were assessed. Results revealed a dose-dependent increase in nutrition intake with higher levels of bamboo leaf supplementation, indicating improved feed consumption in supplemented groups. Productivity, measured as total weight gain per hectare, exhibited a similar trend, with the Medium and High Dose groups demonstrating higher productivity compared to the Control and Low Dose groups. Analysis of growth performance, represented by average daily gain (ADG), further supported these findings, showing higher ADG in the Medium and High Dose groups. Bamboo leaf supplementation positively influenced nutrition intake, productivity, and growth performance in Boer goats. These results suggest the potential of bamboo leaves as a valuable dietary supplement for enhancing goat farming efficiency and livelihoods, particularly in regions where bamboo is abundant.

Abstract

Bamboo lobster (Panulirus versicolor) is a marine commodity with promising prospects for aquaculture development. Feed is a critical issue in the growth of P. versicolor, necessitating an effective, affordable solution that promotes optimal growth. This study aimed to examine the use of sosodek fish meal (A. lacunasus) as a nutrient source to enhance the growth of P. versicolor. Specimens of P. versicolor (weighing 79.97±38 g) were obtained from local fishermen in Togean District, Tojo Una-Una Regency, Central Sulawesi. The experiment tested the use of sosodek fish meal as a feed ingredient at different percentages: 0% (control), 10% (A), 20% (B), and 30% (C). The lobsters were kept in containers with 25 liters of seawater, with one lobster per container, and each treatment was replicated three times. Feed was given at 5% of body weight, three times daily. Body weight was measured every two weeks. Water quality was maintained within a range suitable for P. versicolor. The results indicated that weight gain and daily growth rates, from highest to lowest, were observed in treatment C (11.84 g and 0.49%/day), B (7.4 g and 0.21%/day), A (2.82 g and 0.09%/day), and control (2.38 g and 0.08%/day). Feed conversion ratios, from lowest to highest, were recorded as C (13.1), B (25.1), A (71.9), and control (64.0). Feed utilization efficiency, from highest to lowest, was seen in treatment C (10.28%), B (4.32%), A (1.85%), and control (1.72%). Survival rates for all treatments were 100%. The analysis showed that individual weight gain, daily growth rates, and feed utilization efficiency were significantly higher, and feed conversion ratios were lower in treatment C (30% sosodek fish meal) compared to other treatments (P<0.05). Utilizing 30% sosodek fish meal as feed ingredient significantly enhances the growth of P. versicolor.

Abstract

This study aims to evaluate the impact of problem-based learning models on students' metacognition in science learning. This type of research is a meta-analysis using the PRISMA 2020 method. Articles from Scopus and Google Scholar databases were collected using Publish or Perish (PoP) software. From 8 articles that met the inclusion criteria, a total of 20 data were obtained to be processed in the meta-analysis. Data analysis was used with JASP software.The results of this metaanalysis research show that problem-based learning model provides moderate effectiveness on students' metacognition in science learning (r RE = 0.67; SE = 0.16; z = 4.24; p < 0.001). This shows that problem-based learning model can improve students' metacognition in science learning. Through PBL, students become more aware of their cognitive strategies and learn to organise them more effectively. Incorporating PBL into the science curriculum can significantly improve students' metacognition, leading to more independent and effective students. Therefore, widely adopting PBL in science education is recommended to achieve better learning outcomes
