Abstract

Ayam Nunukan merupakan plasma nutfah unggas lokal Kalimantan Timur yang memiliki potensi untuk dikembangkan melalui penerapan teknologi reproduksi, salah satunya inseminasi buatan. Keberhasilan inseminasi buatan sangat dipengaruhi oleh kualitas semen yang digunakan, sehingga diperlukan upaya penanganan pascapenampungan untuk mempertahankan mutu spermatozoa. Pengenceran semen menggunakan larutan tertentu bertujuan untuk meningkatkan volume ejakulat dan menjaga kualitas semen selama proses penanganan. Penelitian ini bertujuan membandingkan kualitas semen segar ayam Nunukan dengan semen yang diencerkan menggunakan larutan Ringer Laktat berdasarkan parameter motilitas, viabilitas, dan abnormalitas spermatozoa. Penelitian dilakukan menggunakan rancangan percobaan dengan dua perlakuan, yaitu semen segar (P1) dan semen yang diencerkan dengan Ringer Laktat (P2). Sebanyak delapan ejakulat semen dari ayam pejantan dewasa digunakan sebagai sampel, dengan masing-masing perlakuan terdiri atas empat ulangan. Data dianalisis menggunakan uji Wilcoxon Signed Ranks Test pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa pengenceran menggunakan larutan Ringer Laktat tidak memberikan perbedaan yang signifikan secara statistik (p>0,05) terhadap motilitas, viabilitas, maupun abnormalitas spermatozoa. Nilai rata-rata motilitas pada P1 dan P2 masing-masing sebesar 69,75% dan 74,25%, viabilitas sebesar 86,75% dan 83,06%, serta abnormalitas sebesar 83,13% dan 85,19%. Disimpulkan bahwa larutan Ringer Laktat mampu mempertahankan kualitas semen ayam Nunukan tanpa menyebabkan penurunan mutu spermatozoa secara signifikan, sehingga berpotensi digunakan sebagai media pengencer pada penanganan semen untuk keperluan inseminasi buatan.

Abstract

Penelitian ini bertujuan untuk menganalisis kelayakan finansial dari usaha peternakan kambing yang dijalankan oleh Peternakan Kandang Hijau Makmur di Jalan Purwodadi, Kelurahan Lempake, Kecamatan Samarinda Utara, Kota Samarinda. Metode penelitian yang digunakan adalah studi kasus dengan pendekatan deskriptif dan kuantitatif. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi, kemudian dianalisis menggunakan parameter kelayakan finansial yaitu Revenue Cost Ratio, Payback Period, dan Return on Investment. Hasil penelitian menunjukkan bahwa usaha peternakan ini layak untuk dijalankan secara finansial. Nilai R/C Ratio sebesar 18,7 mengindikasikan bahwa setiap pengeluaran sebesar Rp1 menghasilkan penerimaan sebesar Rp18,7. Payback Period tercapai dalam waktu 2 tahun 7 bulan 29 hari, yang menunjukkan bahwa modal investasi dapat kembali dalam jangka waktu menengah. Namun, nilai Return on Investment yang diperoleh relatif rendah, yaitu sebesar 0,05%. Rendahnya Return On Investment ini terutama disebabkan oleh fluktuasi penjualan, dimana pada bulan Juli tidak terjadi penjualan kambing, sehingga pendapatan hanya bersumber dari penjualan feses. Kurangnya pemahaman finansial juga membuat peternak sulit melakukan diversifikasi produk, menghitung potensi keuntungan, dan merancang strategi pemasaran yang sesuai. Oleh karena itu, peningkatan pengetahuan finansial menjadi faktor penting agar calon peternak memiliki acuan yang jelas dalam memulai usaha ternak kambing secara rasional, efisien, dan berkelanjutan.

Abstract

Bali cattle are an indigenous Indonesian beef cattle breed with an important role in supporting beef production and rural livelihoods. In Bima, Bali cattle are an important livestock resource, and accurate body weight information is useful for supporting feeding and other management practices. However, the availability of weighing facilities at the farm level is often limited, making body weight estimation based on morphometric measurements a practical alternative. This study aimed to compare body weight estimates obtained using the Djagra, Winter, and Schoorl formulas and to determine their deviations from the reference body weight in 1–2-year-old male Bali cattle raised under a semi-intensive management system. The study was conducted in March 2023 in Mbawa Village, Donggo District, Bima Regency, West Nusa Tenggara Province, Indonesia. Data were collected from 50 male Bali cattle using heart girth and body length measurements for body weight estimation. The results showed that the mean heart girth and body length were 129 ± 5.31 cm and 114.50 ± 5.34 cm, respectively. The estimated body weights were 268.48 ± 28.87 kg using the Djagra formula, 271.44 ± 29.19 kg using the Winter formula, and 228.10 ± 16.23 kg using the Schoorl formula. Relative to the reference body weight of 223.75 kg, the percentage deviations were 18.48%, 19.61%, and 5.49%, respectively. Among the three formulas evaluated, the Schoorl formula produced the estimate closest to the reference value in the study population. However, its performance should be interpreted as population-specific because the accuracy of body weight estimation formulas may vary according to animal characteristics and management conditions. Further validation using actual body weight measurements is required before applying the formulas to other Bali cattle populations.

Abstract

Halal meat now moves through supply chains that cross religious, scientific and legal boundaries, and the method of slaughter sits where these boundaries meet. This review synthesizes evidence published mainly between 2013 and 2026 on halal slaughter with and without stunning, covering bleeding efficiency, stress physiology, meat quality, Islamic ethics, consumer knowledge and regulation. Peer-reviewed studies from Scopus, Web of Science, PubMed and ScienceDirect were combined with standards, fatwas and court decisions and analyzed in five themes. In halal-slaughtered cattle, blood loss rose from 3.55% of live weight after 5 min of bleeding to 3.99% after 15 min, and longer bleeding gave a more compact myofibrillar structure and firmer meat without changing pH or color. Head-only reversible electrical stunning did not reduce blood loss in lambs or goats, whereas head-to-back stunning in goats lowered bleeding efficiency and reduced oxidative and microbial stability. Field data from Indonesian abattoirs and Eid al-Adha sacrifices locate the largest welfare risks before and around the cut: roping and casting, blunt knives and delayed loss of consciousness, with 57% of Bali cattle moving or trying to stand after the neck cut. Islamic sources place welfare inside the halalan tayyiban requirement, yet surveys show that many Muslim consumers believe certification covers farm practices it does not address. Regulatory positions range from mandatory pre-cut stunning in several European jurisdictions, upheld by the Court of Justice of the European Union in 2020 and the European Court of Human Rights in 2024, to conditional acceptance of reversible stunning in Indonesia, Malaysia and the Gulf states and rejection in Pakistan. The stunning debate has drawn attention away from controllable points such as restraint, knife sharpness, cut position and slaughterer competence. Harmonization is more likely to come from shared, measurable welfare outcomes that religious authorities can verify than from agreement on stunning alone.

Abstract

This study compared the production performance of broiler chickens reared in closed-house and open-house systems on partner farms of PT Ciomas Adisatwa in Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan. Data covered three rearing periods per system between December 2024 and February 2025, using Lohmann MB 202 birds harvested up to 35 days of age. Feed consumption, harvest weight, daily body weight gain, feed conversion ratio (FCR), mortality, and performance index (PI) were recorded. Each system was represented by three periods (n = 3) and compared with a two-sample t-test. Welch's test, mean differences with 95% confidence intervals, Hedges' g, and Holm correction were added to assess the precision of the estimates. Mortality was lower in the closed house (2.83 ± 1.26% vs 5.47 ± 0.91%; P = 0.042) and PI was higher (403 ± 12 vs 358 ± 25; P = 0.048). Neither difference remained after Holm correction (P = 0.254), and the PI difference was not significant under Welch's test (P = 0.073). FCR (1.507 vs 1.564), feed consumption (3,019 vs 3,129 g/bird), and harvest weight (2.05 vs 2.00 kg) did not differ significantly (P > 0.05). Per 1,000 day-old chicks, the closed house yielded about 26 more surviving birds and 98 kg more live weight. The closed house tended to perform better in mortality and PI, but three periods per system are too few to confirm the difference. Follow-up studies need farm-level replication and recorded microclimate data.

Abstract

Sistem penggemukan sapi potong secara intensif pada skala kecil dan menengah memiliki peran penting dalam memenuhi kebutuhan daging lokal dan mendukung stabilitas ekonomi regional di Kalimantan Timur. Penelitian ini bertujuan untuk menganalisis struktur biaya produksi, penerimaan kotor, pendapatan bersih usaha, dan kelayakan ekonomi peternakan sapi potong intensif "Kandang Hijau" yang berlokasi di Kelurahan Lempake, Kecamatan Samarinda Utara, Kota Samarinda. Penelitian dilaksanakan pada Februari hingga Mei 2026 menggunakan pendekatan studi kasus tunggal secara komprehensif dengan data yang diperoleh melalui pemantauan lapangan primer, catatan teknis, dan wawancara terstruktur dengan pengelola peternakan. Parameter keuangan dianalisis dengan menghitung total biaya tetap, total biaya operasional variabel, penerimaan kotor tahunan, laba bersih, dan indeks kelayakan finansial menggunakan Revenue-Cost Ratio (R/C Ratio). Hasil empiris menunjukkan bahwa peternakan mengoperasikan sistem penggemukan intensif dengan total 1.000 ekor sapi potong per tahun yang terbagi dalam 4 siklus produksi, masing-masing 250 ekor selama periode 3 bulan. Total biaya produksi tahunan sebesar Rp13.471.166.667,00, yang didominasi oleh biaya variabel (99,81%), dengan pengadaan sapi bakalan sebagai komponen biaya utama. Total penerimaan kotor tahunan mencapai Rp16.780.000.000,00, yang diperoleh dari penjualan sapi Bali standar dan sapi persilangan eksotik berukuran besar dengan harga premium. Kinerja keuangan tersebut menghasilkan pendapatan bersih usaha tahunan sebesar Rp3.308.833.333,00 bagi pemilik. Nilai R/C Ratio sebesar 1,25 menunjukkan bahwa usaha agribisnis peri-urban ini layak secara ekonomi, efisien, dan memiliki ketahanan struktural terhadap fluktuasi harga input yang dipengaruhi kondisi pasar.

Abstract

The availability of adequate feed resources is an important factor determining the potential development of ruminant livestock in a region. This study aimed to estimate the availability of forage resources, total feed supply, carrying capacity, and the potential capacity for increasing the ruminant livestock population in East Kutai Regency, East Kalimantan. A quantitative descriptive approach was applied using secondary data obtained from the Central Statistics Agency of East Kutai Regency for 2024. Feed resources were estimated from plantation areas, agricultural land, and crop residues and expressed as dry matter (DM). The carrying capacity was calculated from total feed availability based on a dry matter requirement of 6.25 kg DM livestock unit⁻¹ day⁻¹, while the potential capacity for increasing the ruminant livestock population (KPPTR) was determined by subtracting the existing livestock population from the estimated carrying capacity. The results indicated that plantation areas contributed 412,448.81 Mg DM year⁻¹, while agricultural crop residues contributed 20,180.04 Mg DM year⁻¹. Agricultural land provided an additional 4,037.38 Mg DM year⁻¹. Consequently, total feed availability varied substantially among subdistricts, with Muara Wahau, Bengalon, Kongbeng, Sandaran, and Karangan among the areas with relatively high feed resources. The estimated carrying capacity of East Kutai Regency reached 193,074.67 livestock units (AU), compared with an existing ruminant population of 16,975.48 AU, resulting in a theoretical KPPTR of 176,099.19 AU. Muara Wahau recorded the highest KPPTR, whereas Sangatta Utara and Sangatta Selatan showed negative values. These findings indicate considerable feed-based potential for ruminant livestock development, although actual expansion should consider forage accessibility, seasonal availability, feed quality, land-use conditions, and farmer socioeconomic factors.

Abstract

This study aimed to determine the effect of different row spacing on the increase in plant height, leaf number, stem diameter, fresh weight, and dry weight of Indigofera zollingeriana plants. The study was conducted in Semoi Dua Village, Sepaku Subdistrict, North Penajam Paser Utara (PPU) from December 2017 to March 2018. The experiment used a Randomized Block Design. The treatments were (p1) row spacing of 50 x 100 cm, (p2) spacing of 75 x 100 cm, (p3) spacing of 100 x 100 cm, and (p4) spacing of 125 x 100 cm, each replicated six times. Data were analyzed by analysis of variance (ANOVA) and continued by Duncan's Multiple Range Test (DMRT) at the 5% level. The results showed that 50 x 100 cm plant spacing gave a significantly better result on height increase, number of leaves, stem diameter, and fresh and dry weight of Indigofera zollingeriana seedlings compared to the wider spacings.

Abstract

Feed availability is a key factor determining the development of ruminant livestock. This study aimed to quantify the potential production of forage from paddy fields, plantations, and agricultural crop residues (HHSP), determine the potential carrying capacity for increasing the ruminant livestock population (KPPTR), and identify ruminant livestock-based areas in Kutai Kartanegara Regency. This descriptive study used secondary data from 2021 obtained from the Central Statistics Agency and the Agriculture and Livestock Office of Kutai Kartanegara Regency across 18 districts. Forage production was estimated using the Nell and Rollinson method, while carrying capacity and KPPTR were calculated based on a dry matter requirement of 6.25 kg ST⁻¹ day⁻¹. Livestock-based areas were identified using Location Quotient (LQ) analysis. The potential forage production reached 268,113.51 Mg DM year⁻¹, consisting of 126,891.32 Mg DM year⁻¹ from agricultural crop residues, 100,349.70 Mg DM year⁻¹ from paddy fields and fallow land, and 40,872.50 Mg DM year⁻¹ from plantations. This forage resource had the capacity to support 117,529.21 animal units (AU), while the actual livestock population was 35,034.46 AU, resulting in a KPPTR of 82,494.75 AU. Sixteen districts had positive KPPTR values, with Tenggarong Seberang, Loa Kulu, and Muara Kaman ranking highest, whereas Samboja and Muara Wis had negative values. Eight districts were identified as ruminant livestock-based areas (LQ > 1), namely Muara Wis, Samboja, Loa Kulu, Kenohan, Tenggarong Seberang, Marang Kayu, Kota Bangun, and Muara Muntai. Kutai Kartanegara Regency still has considerable potential to increase its ruminant livestock population based on locally available feed resources.
