Abstract

This study aimed to examine the effect of marlin fish (Istiompax indica) byproduct meal (MFBM) mixed with some other feed ingredients such as yellow corn (YC), rice bran (RB), broken rice (BR), and top mix (TM) as a mixture feed (MF) in replacement fractionally a commercial ration (CR) on carcasses and organs of broiler chickens. As a comparison,  commercial local fish meal (CLFM) was used instead of MFBM in the MF. A total of 100 DOCs, strain MB 202, were raised for 35 days of age to feed the experimental rations. The experimental rations were: CR= 100% CP511/512 (control), MFBM4= 80% CP511/512 + 20% MF1 containing 4% MFBM, MFBM8= 80% CP511/512 + 20% MF2 containing 8% MFBM, CLFM4= 80% CP511/512 + 20% MF3 containing 4% CLFM, and CLFM8= 80% CP511/512 + 20% MF4 containing 8% CLFM. The research used a completely randomized design (CRD) with five treatments, four replications, and two subsamples. Data were analyzed by Analysis of Variance (ANOVA) and continued by Duncan’s multiple range taste (DMRT) only if the results detected a significant difference. This study showed that at 4% usage within the MF, using MFBM did not indicate a significant difference in the whole carcass and cuts-up weights than using CLFM. However, at the level of 8% within an MF, the former was significantly higher (p<0.05) on the whole carcass and breast weight than the latter. In conclusion, marlin fish byproduct meal (MFBM) could be used up to 8% to produce better whole carcass and breast weight compared to commercial local fish meal (CLFM) without adverse effects on the internal organs of broilers.

Abstract

One of the obstacles often faced in broiler farming is the decline in performance and disease attacks. Efforts that need to be made to improve health and prevent disease attacks are by increasing non-specific immune responses through the provision of feed additives such as prebiotics. Prebiotics are non-digestible compounds and function as a food source for good microorganisms in the digestive tract. One such source is natural honey which contains oligosaccharides so that it acts as a prebiotic. The purpose of the study was to evaluate the provision of drinking water containing natural honey oligosaccharides to improve the performance and health of broiler. The research was conducted experementally using a completely randomized design (CRD) consisting of four treatments and the replications. The research treatments included: P0:control, P1:0.5% natural honey oligosaccharides (v/w), P2:1% natural honey oligosaccharides (v/w), and P3:1.5% natural honey oligosaccharides (v/w). The research variables include: ration consumption, body weight gain, final body weight, ration conversion, ration efficiency, drinking water consumption, mortality, feces shape and feces color. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s multiple range test. The results indicated that ration consumption, body weight gain, final body weight and ration efficiency, drinking water consumption, and health increased in the treatment containing natural honey oligosaccharides and decreased in the ration conversion and mortality of broiler relative to the control. The study concluded that the provision of drinking water containing honey oligosaccharides as prebiotic of 0.5 to 1.5% improved both the performance and health status of broiler.

Abstract

Purpose of the study: This study investigates how transformative school leadership integrates character values into the school culture of Imelda Health Vocational School Medan through ethno-social pedagogical practices. The main objective is to analyze the principal’s leadership model and its contribution to strengthening character formation grounded in the school’s socio-cultural context. The study is based on the premise that school leadership extends beyond administrative duties toward shaping a value-oriented educational ecosystem. Methodology: A qualitative design was employed using in-depth interviews, participatory observation, and document analysis. Data were processed through Miles and Huberman’s interactive analysis model consisting of data reduction, data display, and conclusion drawing. Main Findings: The findings reveal two interconnected dimensions of leadership practice. First, the managerial dimension includes policy development, standard operating procedures, human resource capacity-building, the teaching factory curriculum, and evaluation systems that embed character-oriented principles. Second, the cultural and ethical dimension is demonstrated through the leader’s moral exemplarity, consistent ethical conduct, and humanistic disciplinary narratives. Together, these practices cultivate a shared cultural habitus that reinforces character development and strengthens the school’s socio-pedagogical environment. Novelty/Originality of this study: This study proposes an integrative framework of transformative leadership that blends managerial system design with socio-cultural character formation. The model contributes to character education policy and implementation by demonstrating how socio-cultural values can shape school culture and guide value-based decision-making. It adds to contemporary scholarship by linking transformative leadership, character formation, and ethno-social pedagogy within vocational education.
