Abstract. Authors. 2019. Daily activity and diet of Talaud bear cuscus (Ailurops melanotis Thomas, 1898) on Salibabu Island, North Sulawesi, Indonesia. Biodiversitas 20: 2636-2644. Talaud bear cuscus (Ailurops melanotis) is an endemic species in the Sangihe and Talaud Islands, North Sulawesi, Indonesia. This species is critically endangered in the IUCN Redlist, with a declining population trend. As a protected species in Indonesia, there has not been any specific research on this species. This research aimed to determine the daily activity pattern of talaud bear cuscus based on sex and age classes, and provide the first preliminary data on its dietary diversity and preference. Data collection was conducted on Salibabu Island (Talaud Islands District, North Sulawesi, Indonesia) for approximately three months (May-July 2016). The talaud bear cuscus spent most of its time resting 78.19%, moving 14.98%, feeding 3.49%, grooming 3.06%, and social 0.28%. Talaud bear cuscus fed on 22 species in its daily diet consisting of 20 tree species and 2 liana species. Cuscus fed mainly on young leaves (57.48%) followed by petioles (leaf stalk) (17.60%), mature leaves (15.33%), bud (7.19%), flowers (1.32%) and unripe fruit (1.07%). This preliminary data about the behavior, activity patterns, and diet of talaud bear cuscus, in general, can be used as supporting information in cuscus conservation efforts, especially habitat management related to the availability of feed resources and to determine the time of the survey and to understand the general behavior and ecology of this species.
Abstract. Repi T, Masy’ud B, Mustari AH, Prasetyo LB. 2020. Population density, geographical distribution and habitat of Talaud bear cuscus (Ailurops melanotis Thomas, 1898). Biodiversitas 21: 5621-5631. The Talaud bear cuscus (Ailurops melanotis) has been reported from Sangihe (the largest island in the Sangihe Island group) and Salibabu (within the Talaud Islands). As an endemic species of Indonesia, this species is rare and there is no certainty regarding its precise geographic distribution or population size. This research aimed to estimate population density and provide the first preliminary data on its geographical distribution, as well as general description of its habitat. Our research shows that A. melanotis occurs on three islands: Salibabu Island, Nusa Island, and Bukide Island, and probably also exists in the Sahandaruman mountain on Sangihe Island. Our population surveys estimate, population density on each island as: Salibabu: 3.69 ± 2.54 ind/km2, with an estimated total population of 28.95 individuals, Nusa Island: was 12.31 ± 2.58 ind/km2, with an estimated population of 19.08 individuals, and Bukide Island: 7.17 ± 1.79/km2, with an estimated population of 10.40 individuals. Information regarding population is a key guiding factor in conservation efforts, where population size is related to extinction risk (threat status) and its geographical distribution, this can help to determine conservation priorities for species or habitats.
Penelitian ini bertujuan untuk mengetahui kualitas fisik ayam broiler (bobot potong, bobot karkas, persentase karkas dan pH daging) dan mutu hedonik (warna dan aroma daging) di Kecamatan Telaga Biru, Kabupaten Gorontalo. Penelitian ini menggunakan metode observasi, dengan melakukan kunjungan langsung dan mengamati peternakan ayam broiler serta melakukan wawancara dan pengukuran kualitas fisik ayam. Data dianalisis menggunakan statistik deskriptif, selanjutnya untuk mengetahui ada tidaknya perbedaan kualitas fisik, dan mutu hedonik di tiap lokasi digunakan uji Kruskal Wallis dan uji lanjut Mann Whitney U. Hasil penelitian menunjukkan bahwa kualitas fisik ayam broiler di Kecamatan Telaga Biru Kabupaten Gorontalo memiliki nilai pH normal yaitu 5,72±0,46–6,15±0,50, dengan rata-rata bobot potong 2,03±0,10–2,18±0,25 Kg, bobot karkas 1,54±0,18 kg–1,61±0,20 Kg dan persentase karkas sebesar 73,24±8,51%–75,32±6,20%. Rata-rata mutu hedonik warna daging ayam broiler di Kecamatan Telaga Biru Kabupaten Gorontalo berkisar dari putih pucat dan merah pucat dan untuk mutu hedonik aroma daging sama untuk seluruh lokasi yaitu berbau amis.Kata Kunci: Kualitas Fisik, Persentase Karkas, Broiler, Mutu Hedonik
Penelitian ini bertujuan untuk mengetahui kualitas semen ayam KUB menggunakan pengencer ringer dextrose dan ringer laktat pada suhu 5?. Pengumpulan data variabel motilitas, viabilitas, dan abnormalitas yang diperoleh dalam penelitian ini dicatat kemudian ditabulasi menggunakan program excel kemudian dianalisis secara deskriptif analitik. Variabel penelitian yang diamati adalah motilitas, viabilitas dan abnormalitas. Hasil penelitian menunjukkan bahwa penggunaan ringer laktat mampu mempertahankan kualitas semen ayam KUB dengan lama simpan 6 hari dengan menghasilkan motilitas, viabilitas yang lebih baik serta tingkat abnormalitas yang lebih rendah dibandingkan dengan pengencer ringer dextrose yang hanya mampu mempertahankan kualitas semen dengan lama simpan 4 hari. Berdasarkan hasil ini dapat disimpulkan bahwa Pengencer ringer laktat memiliki kualitas semen yang lebih tinggi dengan lama simpan mencapai 6 hari dengan motilitas individu mecapai 60%, viabilitas 48,76%, dan abnormalitas 6,36% sedangkan pengencer ringer dextrose dapat mempertahankan kualitas semen dengan lama simpan 4 hari dengan motilitas individu 53%, viabilitas 30,1% dan abnormalitas 7,13%.Kata kunci: Ayam KUB, Ringer Dextrose, Ringer Laktat, Semen.
