Abstract

Bromelain as a single enzyme is widely used as a meat tenderizer; however this can damage the meat cell’s. The effect of adding multienzyme Phyprozyme HP in feed is not yet known, so it needs to be investigated. This study aimed to evaluate the growth performance of broilers with the addition of single and multienzymes. This study used 42 Lohman MB 202 Grade Platinum broilers aged 21 to 35 days, using 6 treatments and 4 replications. P0 as the control feed. Bromelin was added in feed at the dose of P1: 600 GDU/kg, P2: 1200 GDU/kg, P3: 1800 GDU/kg, P4: 2400 GDU/kg, and P5: 3000 GDU/kg. Phyprozyme HP was added at P1: 0.19 g/kg, P2: 0.26 g/kg, P3: 0.33 g/kg, P4: 0.40 g/kg, and P5: 0.47 g/kg. Parameters measured included body weight, body weight gain, and carcass percentage. The results were analyzed using One-Way ANOVA. The addition of bromelain in feed decreased body weight, while the addition of multienzyme significantly improved broiler performance up to a dose of 0.33 g/kg feed. The addition of bromelain decreased carcass percentage to 11.07%, while the addition of multienzyme increased carcass percentage to 8.83%, but decreased it to 7.68% at the highest dose.

Abstract

The practice of ethno-entomophagy has been going on for hundreds of years in Indonesia and has become a local culture and wisdom that still continues today. Of the many edible insects, Valanga nigricornis is one of the most popular. The aim of this research is to determine the views of local communities towards entomophagy and its impact on natural pest control and environmental sustainability. The method used is phenomenological research using snowball sampling techniques and quantitative descriptive research using purposive sampling techniques. The research area is 4 hectares of rice fields. Sampling was carried out in 5 plots with an area of 300 m2 each and was carried out once a year continuously for 3 years. The sampling time was chosen at the beginning of the dry season which is the peak time for corn production. The research results show that the main reasons and beliefs of local people towards the practice of entomophagy are caused by cultural factors, natural pest control, economic factors, and favorite foods. The results of sampling regarding Valanga nigricornis pest attacks showed low values for 3 consecutive years. The conclusion of this research is that ethno-entomophagy has a positive impact on local control of the natural pest Valanga nigricornis.

Abstract

Self-directedness is a crucial skill for prospective science teachers, and the Think-Pair-Project-Share (TP2S) model has shown promise in fostering collaboration and critical thinking. This aim study to investigates the effectiveness of TP2S in promoting self-directed learning among these future educators. This research aims to determine the effectiveness of the think-pair-project-share (TP2S) learning model in facilitating the self-directedness of prospective science teachers. This quantitative research uses a nonequivalent control group design. The population in this study were second semester students, while the research sample consisted of 72 students. The self-directedness data collection technique uses an instrument in the form of a scale. Based on the results of the paired sample T test, it can be seen that both experimental classes obtained a Sig value. (2-tailed) 0.000. It can be concluded that the paired sample T test value in the experimental class is 0.000<0.05 so that there is a significant difference in results between the pretest and posttest scores (H0 is rejected). It can be concluded that there is a difference in self-directedness between students who study human and environmental subjects using the think pair project share model and those who use the conventional model. It is known that the application of the TP2S learning model has an effect on the self-directedness of prospective science teachers. The implications of this research support and strengthen the results of theoretical studies that the TP2S learning model is a student-centered learning model that utilizes the ability to manage learning strategies independently.

Abstract

This study discusses analysis level of difficulty in the aspect of analytical thinking skills in science learning with the aim of providing insights on how students and educators can address these difficulties, ultimately contributing to a more effective science education system that fosters critical and analytical thinkers. By using the research methods The study used a quantitative methods using Rasch analysis and Confirmatory Factor Analysis (CFA) to determine the level of difficulty of students' analytical thinking skills aspects. Based on the analysis, the aspects of "specifying (54%)" and "generalizing (55%)" were found to be the most difficult for students, while the aspects of "analizyng error (62%)", "matching (68)" and "classifying (73%)" were considered easier. These findings also indicate that students tend to struggle with identifying the logical consequences of information and in constructing generalizations or new principles.

Abstract

One of the most prevalent health problems in Indonesia is anemia, particularly among adolescent girls, where concerns about excessive weight gain may reduce adherence to iron supplementation. Spirulina is a potential alternative supplement rich in iron and nutrients that support hematopoiesis and may address these concerns. This study aimed to analyze the effect of spirulina supplementation on body weight in anemic adolescent female Wistar rats. This experimental study used 25 female Wistar rats divided into five groups: normal control (NC) received a standard BR diet, positive control (PC) received a low-iron diet to induce anemia, and three treatment groups received spirulina at doses of 25, 50, and 100 mg/kg body weight (T1–T3) for 21 days. Body weight was measured before anemia induction, after anemia induction, and following supplementation. The results showed a significant overall difference in body weight gain among the groups (p < 0.001), which was mainly driven by differences between the normal control and positive control groups. However, post hoc analysis indicated no significant differences in body weight gain between the positive control group and treatment groups 1, 2, and 3 (p > 0.05). Body weight in the treatment groups increased by 22.8–27 g, indicating recovery toward baseline values. Although these differences were not statistically significant, spirulina supplementation may contribute to anemia recovery, as reflected by improvements in body weight. In conclusion, spirulina shows potential as a nutritional supplementation strategy that does not induce excessive weight gain while supporting iron-related nutritional needs.

Abstract

Spirulina is a microalga with spiral or linear trichome shapes that has potential in industrial and food sectors due to its rich nutritional content. Spirulina can live in various aquatic habitats with different environmental conditions. Differences in cultivation environments can affect the morphological characteristics of Arthrospira due to phenotypic plasticity, making morphology-based identification prone to errors. Therefore, molecular identification using the 16S rRNA gene for phylogenetic analysis is necessary. This study aims to identify and analyze the genetic relationships of Spirulina from freshwater and brackish water based on 16S rRNA gene sequences. Freshwater Spirulina samples were taken from Bogor (BGR) and Yogyakarta (MRP), while brackish water Spirulina was taken from Jepara (JPR). DNA extraction was performed using the Zymo Research Quick-DNA Fungal/Bacterial Miniprep Kit, amplification of the 16S rRNA gene was conducted through PCR, followed by DNA sequencing. Phylogenetic analysis was carried out using MEGA11 to construct the phylogenetic tree. The morphology of strains BGR and MRP showed straight and thin filaments, whereas JPR had spiral and relatively long filaments. Sequencing analysis results showed that strains JPR and MRP had the closest homology similarity to Arthrospira sp. IAQUASC-C0001 with percentages of 99.34% and 99.12%, respectively. Meanwhile, Spirulina from BGR had the closest homology similarity to Arthrospira fusiformis strain AICB 668 with a percentage of 99.78%. Phylogenetic analysis indicated that strains BGR, JPR, and MRP are more closely related to Arthrospira than to Limnospira.
