Abstract

Feed cost represents the largest component of poultry production, making feed efficiency a key determinant of economic sustainability. Indigenous chickens are economically and culturally important but exhibit relatively slow growth and suboptimal feed utilization. This study evaluated the effects of different dietary protein regimens on growth performance of indigenous chickens, focusing on feed conversion ratio (FCR), feed efficiency (FE), and performance index (PI). A total of 168 day-old chicks were reared for 10 weeks in a completely randomized design (four treatments, six replicates). The treatments consisted of: T0 (22% crude protein for 3 weeks followed by 15% for 7 weeks), T1 (18% for 4 weeks followed by 16% for 6 weeks), T2 (18% for 2 weeks, 16% for 4 weeks, and 14% for 4 weeks), and T3 (18% for 3 weeks, 16% for 3 weeks, and 14% for 4 weeks). Dietary protein level significantly affected FCR and FE (P<0.05). T0 produced the lowest FCR (3.35) and highest FE (37.20%), whereas T2 and T3 showed higher FCR values (4.47) and lower FE (25–28%). Results indicate that adequate protein supply during the starter phase is critical to long-term feed efficiency. Diets with balanced protein levels and appropriate energy–protein ratios improve nutrient utilization and overall production performance in indigenous chickens.

Abstract

Livestock waste management in Lempake Subdistrict, Samarinda City, presents a significant challenge in achieving sustainability within the livestock sector, especially in urban areas. Improper livestock waste management can lead to water, air, and soil pollution, negatively affecting health and environmental quality. This community service program aims to optimize livestock waste management by applying Circular Economy (CE) principles to reduce environmental impact by recycling livestock waste into biogas and organic compost. The program involves the Krida Karya Utama Farmers Group as the subject of the service, with the primary goal of enhancing the community’s knowledge and skills in sustainable waste management. The methods used include training, outreach, and the application of Gender Equality and Social Inclusion (GESI) principles to ensure the involvement of women in waste management. The program results show an increase in the farmers’ knowledge and skills, which directly impacts the economic resilience of farming families, especially for women. Additionally, Circular Economy-based waste management can reduce pollution and optimize the use of waste as a valuable resource for the community. Despite challenges related to infrastructure and the community’s understanding of the circular economy, this program has contributed positively to the sustainability of the livestock sector and the socio-economic welfare of the community.
Efek Ekstrak Daun Karamunting (Melastoma Malabathricum L.) terhadap Sifat Fisik, Penerimaan Organoleptik, Aktivitas Antoksidan, dan Viabilitas Probiotik pada Yogurt Hasan, Abdullah Kiemal Sholeh; Ismanto, Arif; Indana, Khoiru; Fajrih H, Nurul; Nur Wahyuningtyas, Amalina

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak daun karamunting (Melastoma malabathricum L.) terhadap sifat fisik, aktivitas antioksidan, viabilitas probiotik, dan penerimaan organoleptik yogurt. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan konsentrasi ekstrak (0%, 1,5%, 3%, 4,5%, dan 6%) dan empat ulangan. Hasil menunjukkan bahwa penambahan ekstrak secara signifikan meningkatkan aktivitas antioksidan yogurt, dengan nilai IC50 terendah pada konsentrasi 6% (115,6 µg/mL). Sebaliknya, viabilitas bakteri asam laktat (BAL) menurun linear dengan peningkatan ekstrak, meskipun seluruh perlakuan masih memenuhi standar minimal (>10⁷ CFU/mL). Penambahan ekstrak juga menyebabkan penurunan viskositas dan kecerahan yogurt, serta peningkatan nilai warna a* dan b*. Nilai pH tidak berbeda nyata antar perlakuan, menunjukkan stabilitas keasaman. Penilaian organoleptik menunjukkan bahwa yogurt dengan penambahan ekstrak hingga 3% masih diterima dengan baik oleh panelis. Dengan demikian, konsentrasi optimal ekstrak daun karamunting dalam yogurt adalah 3%, yang mampu meningkatkan aktivitas antioksidan tanpa mengurangi kualitas fisik dan sensorik secara signifikan.
