Abstract

The objective of this research was to identify the dynamic population of beef cattle at North Pamona of Poso regency. This research was an analytical descriptive study conducted using survey method on 572 respondents taken using a purposive sampling method from all villages at         North Pamona. The result showed that the composition of beef cattle were 533 (34.88%) bull and 995 (65.12%) cows. The total number of bull calves, bullock and bull were 93, 100 and 340, respectively, while the heifer calves, heifers and cows were 135, 130 and 738 respectively.          The birth rate was 30.89% or 14.83% of the total population whereas the motility rate was 2.7% so that the natural increase was 12.13%.  Key words: Beef cattle, population and reproductivity.

Abstract

Produktivitas dalam usaha pemeliharaan ternak kambing memiliki peranan yang sangat menentukan untuk meraih hasil yang cukup optimal. Reproduksi induk merupakan gambaran dari kemampuan induk bereproduksi, terutama dalam kemampuan induk untuk melahirkan sejumlah anak dan kemampuan untuk menyusui selama anak periode prasapih. Jumlah anak sekelahiran (litter size) sangat menentukan laju peningkatan populasi ternak kambing, karena jumlah anak sekelahiran yang tinggi dan tetap hidup sampai sapih akan dapat mempengaruhi kenaikan populasi. Penelitian ini bertujuan untuk mengetahui seberapa besar tingkat produktivitas induk kambing di Desa Dolago Kec. Parigi Selatan Kab. Parigi Mautong. Produktivitas induk kambing di Desa Dolago baik, hal ini dapat dilihat dari tingginya kelahiran, dengan jumlah sebesar 111,11% serta dalam kurun waktu satu tahun jumlah anak ternak kambing yang lahir dari 18 ekor induk adalah 20 ekor terdiri dari 8 ekor jantan dan 12 ekor betina. Hal ini dapat menggambarkan bahwa tingkat produktivitas ternak kambing di Desa Dolago adalah baik.

Abstract

Sulawesi is an island that has high biodiversity. However, utilization of natural resources has been harming habitat of animals. The destructions of their habitat cause some animals become extinct from earth. Tarsius wallacei is one of the primate species from Tarsidae family and is an endemic species of Central Sulawesi region.  This research was done because the status of Tarsius becomes an endangered species. The purpose of this research was to estimate the population of T. wallacei at Lebanu village. This research was conducted during 3 months using Point Count method. The result of this research showed that populations of T. wallacei at Lebanu village are 11 groups and their densities are 0.19 groups/ha.

Abstract

Tarsius wallacei is an endemic mammal of Sulawesi published by Merker, et al on 2010. Even though the distributions, vocalizations and morphometric have been studied well, the ecological aspect especially type of feed was not studied whereas the diet information is an important data for conservation of this endemic species. The objective of the study was collect the variety of tarsius’s prey in the wild. A collection of samples has been conducted from February to October 2015 using sweep net, light trap, and hand capture methods. The results of prey collection show that Tarsius wallacei feed on insects. Thirteenspecies were found as a prey of Tarsius wallacei which consists of 10 order, i.e. Orthoptera, Blattodea, Coleoptera, Araneae, Lepidoptera, Hemiptera, Odonata, Isoptera, Hymenoptera and Homoptera. Proximate analysis of the three orders that belong to the group Insecta indicated the Tarsius wallacei probably consume mainly on Orthoptera with the highest protein content, 69.32%, followed by Lepidoptera (66.51%), and Coleoptera (41,98%)

Abstract

The study to identify the effects of different concentrate supplementation on the reproductive performance of the local rabbits fed with basal ration (i.e.: sweet potato forages – ad libitum) was carried out in Jono Oge village - Biromaru, Donggala–Central Sulawesi. The study used 12 multifarious does which were allocated to four treatments using a Randomized Block design (RBD).  The treatments were as follows: does fed with basal ration (R0); does fed with basal ration supplemented with concentrate at 1% (R1), 2% (R2), and 3% (R3) of body weights.  Litter sizes, weights at birth   and weaning of kids were then recorded.  Results showed that concentrate supplementation for the  local rabbits fed with basal ration of sweet potato forages did not significantly affect the litter size and  birth-weight of kids but the treatments did significantly affect their weaning-weights (21 day old).

Abstract

The research conducted to estimate the heritability value and genetic correlation of growth traits of crossbred F (indigenous hens X Bangkok cocks) were done over 28 weeks. Five groups of pen mating poultry were used in which one cock and five hens were used for each group. Therefore, there were 5 cocks and 25 hens as parent stock and 152 crossbred F. Variables of the research were body weight of DOC, body weight of 4th weeks and 8th weeks. The variations of body weight by sex were eliminated by transforming the female body weight to male body weight using correction factor. Estimation of heritability value (h²) used an anova of nested design method. Estimation of genetics correlation (rG) used an  ancova of nested design. Results of heritability estimates and genetic correlation showed that the h² was 0.13 for Doc body weight, 0. 67 for 4th weeks, and 0,59 8th weeks. The rG was 0.89 for DOC to 4th week body weight, and 0.55 for DOC to 8th week body weight

Abstract

Tarsius is one of the endemic species of Sulawesi found in various habitat types, namely primary forest, secondary forest and transition secondary forest. This study aims to observe habitat characteristics and estimate the population density of tarsiers (Tarsius dentatus) at Resort II Baturube Morowali Nature Reserve area, North Morowali District. Observation of habitat characteristics uses a Porposive sampling by using the plot line method and estimation of population density using thepoint count method. The results of studies showed that the tarsier habitat began at a height of 312-163 masl with slopes of 4-25%. Habitat temperature ranges from 20.3˚C-29.5˚C and air humidity ranges from 80% -98% while the light intensity that enters the tarsier habitat ranges from 200-3500 lux. Retrieval of data on vegetation components found that tarsier habitats many occupy bamboo and ficus sp. The highest important value index for the three types of tarsier habitat at the tree level is Ficus insipida (Moraceae) (98.36), pole level Pseudolmedia sp (Moraceae) (107.2), sapling level Protium sp (2) (Burseraceae) (70.8), and seedling levelPandanus sp (2) (Pandanaceae) (91.01). The highest Tarsier population density was found in transition secondary forest habitats with a population density of 2.17 individuals / ha, in secondary forests of 1.95 individuals /ha and in primary forests of 1.17 individuals / ha.

Abstract

This research aims to analyze the inbound and outbound flow processes at the frozen food warehouse of UD. Al Barkah in Palu City, Central Sulawesi. Using a qualitative approach with a case study method, the research was conducted in January 2025 with data collection techniques including direct observation, in-depth interviews with 12 key informants, and document analysis. The results show several constraints in UD. Al Barkah's warehouse management includes a time-consuming goods receiving process due to the continued use of physical checking and manual documentation, inadequate implementation of information technology in managing goods movement, and an unintegrated stock management system. This research recommends several improvements, including standardization of operational procedures, implementation of warehouse management information systems, optimization of warehouse layout, enhancement of quality monitoring systems, and development of human resource competencies. Implementing these recommendations is expected to improve operational efficiency, reduce the risk of errors in goods management, and enhance the quality of UD. Al Barkah's frozen food distribution services.
