Abstract

Heat stress is one of the main challenges in livestock farming systems in tropical areas, directly affecting the physiological response and productivity of livestock. Bali cattle, as one of Indonesia's local germplasms, are known to have good adaptability to extreme environmental conditions. This study aims to evaluate the heat tolerance of male and female Bali cattle using the Iberian Heat Tolerance Coefficient (IHTC), Benezra’s Coefficient of Adaptability (BCA), and Thermal Stress Resistance Index (TSRI). Data analysis used the independent samples t-test to compare between male and female sexes under heat stress conditions (THI = 84.8–87.2). The results showed significant differences (P < 0.05) in IHTC and BCA values between male and female Bali cattle, while TSRI did not show significant differences (P > 0.05). Male Bali cattle had lower IHTC values and higher BCA values compared to female cattle. This finding indicates that female Bali cattle have relatively better heat tolerance compared to male Bali cattle.

Abstract

Background: To combat environmental degradation and resource scarcity, a global shift from a linear to a circular economy is necessary. Kefir production offers significant potential for the circular economy by leveraging by-products such as whey and ricotta. Objective: This study describes the application of circular economy concepts within a kefir microenterprise in Samarinda, Indonesia, focusing on waste-recycling practices, profitability patterns, and sustainable business strategies. Method: A mixed-method approach combining digital ethnography, e-commerce data analysis, and indirect cost calculation was used to identify circular processes and their association with production costs. Results: Local producers have successfully transformed waste into functional foods and cosmetics. This study demonstrates that these producers naturally apply circular economy principles through practical experience. Converting by‑products into revenue streams helps offset the low profit margins of basic products, given the large gap between market prices and production costs. Conclusion: The growth and resilience of micro, small, and medium enterprises (MSMEs) in the kefir sector align with sustainability concepts. This article suggests strengthening value chain integration and encouraging greater collaboration among stakeholders to make the transition to a circular model more effective.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan kompetensi peternak dalam mengaplikasikan teknik Inseminasi Buatan (IB) pada ayam kampung melalui pendekatan partisipatif berbasis pengalaman atau learning by doing. Pelatihan dilaksanakan melalui tiga tahapan terstruktur: (1) Matrikulasi yang menyajikan teori dasar, manfaat, dan prinsip IB untuk memperkuat landasan pengetahuan; (2) Praktikum, di mana peserta secara langsung berlatih penanganan pejantan, koleksi dan evaluasi semen, pengenceran, hingga teknik injeksi semen pada ayam betina; serta (3) Diskusi dan Evaluasi untuk mengidentifikasi dan memecahkan masalah praktis. Hasil praktikum dan diskusi menunjukkan bahwa tantangan utama dalam penerapan IB pada ayam kampung adalah penanganan ayam yang efektif untuk meminimalkan stres. Stres yang tinggi pada pejantan dapat menurunkan kualitas dan volume semen, sementara pada betina dapat menghambat eversi kloaka. Untuk mengatasi kendala ini, telah disepakati dan dipraktikkan strategi penyesuaian teknik, yaitu dengan sentuhan ritmis saat stimulasi dan pengkondisian lingkungan yang tenang untuk mereduksi respons liar ayam. Melalui pelatihan ini, peternak mendapatkan keterampilan teknis yang terasah dan kemampuan berpikir kritis dalam mencari solusi di lapangan. Diharapkan kompetensi ini dapat diaplikasikan secara mandiri guna mempercepat perbaikan genetik dan meningkatkan efisiensi peternakan ayam kampung di Kalimantan Timur.
