Abstract

Broiler production in humid tropical regions such as East Kalimantan faces challenges from persistently high temperature and humidity, which can affect feed intake, growth rate, and feed conversion efficiency. This study aimed to examine the correlation among key production parameters feed intake, daily weight gain, feed conversion ratio (FCR), and mortality across commercial broiler farms with different housing systems in East Kalimantan. An observational field study was conducted on four broiler farms rearing Ross, Lohmann, and Cobb strains under both closed-house and open-house environments. Data were analyzed using Pearson correlation after normality testing. The average feed intake was 3.70 ± 0.64 kg/bird, final body weight 2.08 ± 0.13 kg, total body weight gain 2.04 ± 0.13 kg, FCR 1.81 ± 0.23, and mortality 3.92 ± 0.74. A significant positive correlation was found between feed intake and FCR (r = 0.961; p < 0.05), and a very strong correlation between body weight gain and final body weight (r = 1.000; p < 0.01). Broilers raised in closed-house systems showed lower FCR and more stable growth compared to those in open-house systems. These findings highlight the crucial role of microclimatic control in improving feed efficiency and growth performance of broilers in humid tropical environments. Optimizing housing design and environmental management is therefore recommended to enhance productivity and economic efficiency of broiler farming in tropical regions.

Abstract

Sustainable agribusiness transformation in developing regions increasingly depends on adopting circular economy principles to optimize resource efficiency and minimize environmental impact. This study analyzes the implementation of Circular Business Models (CBMs) in livestock waste management as a foundation for achieving green growth and sustainable agribusiness development in Bukit Raya Village, Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan, Indonesia. A qualitative descriptive approach combined with a case study design was employed to examine the socio-economic, managerial, and environmental dimensions influencing CBM adoption among five farmer groups. Primary data were obtained through field observations, semi-structured interviews, and focus group discussions, while secondary data were sourced from institutional and academic reports. The results revealed that 76% of livestock waste, primarily goat and cattle manure, was successfully valorized into biogas and organic fertilizer, resulting in a 40% reduction in LPG use and a 17.7% increase in household income. Compost and biofertilizer commercialization integrated livestock systems into local agribusiness value chains, fostering market-based sustainability. Community-based innovation promoted inclusivity, with women and youth participation reaching 35% of total members. The conceptual framework developed from this study identifies four strategic pillars, resource efficiency, market-oriented integration, community-driven innovation, and institutional facilitation, as essential to transforming rural livestock systems toward a circular and regenerative agribusiness ecosystem. The findings underscore the importance of aligning rural development and policy interventions with circular economy principles to enhance environmental resilience and socio-economic equity within sustainable agricultural systems.

Abstract

Anthracnose disease is one of the most destructive diseases affecting chili pepper (Capsicum annuum L.). The impact of anthranose on production worldwide results in significant yield and quality losses during both pre-harvest and post-harvest stages. Control of this disease has relied use traditional technic with synthetic fungicides. Synthetic fungicides have caused pathogen resistance, environmental contamination, and food safety concerns. Therefore, biopesticides are considered an environmentally friendly and sustainable alternative. This review aims to critically summarize recent studies published between 2015 and 2025 on the application of biopesticides to controlling anthracnose disease in chili pepper. Scientific literature was collected from major databases, including Scopus, ScienceDirect, and Google Scholar. The review highlights the effectiveness of biopesticides from microbial and botanical pesticides. Microbial pesticides such as Trichoderma spp., Bacillus, and Pseudomonas spp. Contribute to disease suppression by producing antimicrobial metabolites and inducing systemic resistance in host plants. Botanical pesticides based on plant extracts and essential oils have antifungal activity by inhibiting spore germination, disrupting fungal cell structures, and antimicrobial chemical compounds. Although biopesticides potential to control anthracnose disease, but remains inconsistent due to environmental factors and formulation constraints. Therefore, improved formulation technologies and integration into integrated disease management strategies are essential to enhance their reliability and adoption in sustainable chili production systems.

Abstract

This study aims to examine the effects of adding calcium soap (CA-PFAD) to the diet on the histology of meat from native chickens aged 12 weeks. This research took place for 6 weeks at the Sesetan Farm barn, Faculty of Animal Husbandry, Udayana University, located on Jalan Raya Sesetan, Gang Markisa, Denpasar, Bali. The design used was a Completely Randomised Design (CRD) with four treatments and six replications, so there were 24 experimental units. Each experimental unit used 3 chickens aged 6 weeks with a body weight of 662.85 ± 21.02 g. The four treatments were levels of calcium soap in ratios of 0%, 2%, 4%, and 6% respectively, for treatments A, B, C, and D. Variables observed included: histology of meat. The results of the study showed that the addition of calcium soap had a significant effect (P<0.05) on epimysium, perimysium of Balitbangtan superior village chickens (KUB), and reduced fat levels in endomysium chest muscle connective tissue of KUB chicken. Based on the research results, it can be concluded that the addition of calcium soap in the ration at levels of 2% can increase the thickness of the epimysium and perimysium and reduce the thickness of the endomysium in KUB chickens. Based on the results of this study, it can be recommended to farmers and future researchers that adding 2% calcium soap to the feed can increase the thickness of the epimysium and perimysium of KUB chickens.
