Abstract

Research problem was lack of information regarding reproductive disorders that cause failure of artificial insemination and factors causing level and stages of reproductive failure of Donggala cattle. Therefore, the objective current study is to explore information of reproduction insemination failure on the stage of ovary and estrus abnormalities that influence the success of artificial insemination and factors causing reproductive disorders in Donggala cattle at each stage of reproduction. This research was a descriptive study carried out in Sindue sub-district, Labuan sub-district, Central Banawa sub-district and South Banawa in Donggala Regency which lasted from July to November 2016. The study used 121 samples of Donggala cattle belonging to the local farmers group. The cattle samples were cows that in dry period, not pregnant, not lactating and not in an estrus state. The variables of this study are reproductive disorders including anatomical ovarian abnormalities (ovarian hypoplasia, persistent corpus luteum) with rectal palpation approach (direct palpation) and abnormalities of estrus (subestrus, disguised estrus, anestrus) with observation. Fertility variables were non rutern rate (NRR) and conception rate (CR) as the focus on the success of Artificial Insemination (AI). Research variables showed that the percentage of reproductive disorders was much lower with NRR and CR values ​​than normal ovarian values ​​higher than AI evaluation results. The conception rate of the first AI results in Donggala cattle with normal anatomy and ovarian function was 95.6% (87/91 head). Furthermore, ovarian hypoplasia was 9%, (2/22 head), whereas persistent corpus luteum did not occur conception.

Abstract

Candlenut agroforestry is the priority land management belongs to the Palolo community, especially in Sigimpu Village and Bakubakulu Village, Sigi Regency. The communities give more and more their attention because the monoculture has showed vulnerability to climate change and global warming. Adopting candlenut agroforestry in land management could be optimized under condition of good community readiness supporting the management system. This study aimed to measure the level of community readiness in the management of candlenut agroforestry in the villages and compare the level of readiness. Community Readiness Model (CRM) is used by taking into account six dimensions and nine levels of readiness. In between of two components, 35 questions based on the dimensions were made. Three respondents were selected representing each community group in the villages by which has four community group each. The results of the CRM analysis show that the level of community readiness is at the initiation level for Sigimpu Village with a value of 6.1 while the level of preparation for Bakubakulu Village is 5.9. In candlenut agroforestry-based forest management in Sigimpu and Bakubakulu Villages there are differences in two dimensions, namely community knowledge with 6,5 and 6,0 of readiness values and resource dimension with 5,8 and 5,2 of values. Thus, the level of community readiness in the study area is in the intermediate level.

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 study aims to determine the growth performance and digestibility of nutrients local chicken and super local chicken using different types of feed. The study was conducted in a Kawatuna Village, Mantikulore Subdistrict, Palu City, on January 13 - April 21, 2019. The study was designed using a Completely Randomized Design wira factorial patterns. The first factor is the type of chicken, namely local chicken and super local chicken, the second factor is the type of feed, which consists of commercial feed (P1), local feed (P2) and functional feed (P3). The study used 180 chickens consisting of 90 local chickens and 90 super local chickens . The variables observed were performance of growth and digestibility. Growth performance consisted of ration consumption, body weight gain, and ration conversied. Digestion consists of digestibility of crude protein and crude fat. The results showed that the interactied between chicken species and feed type had no significant effect (P> 0.05) on the growth performance (feed consumption, body weight gain and feed conversion) and digestibility. (protein and fat). The factor of chicken type had no significant effect (P> 0.05) on growth performances and protein digestibility, but had a very significant effect (P <0.01) on fat digestibility. The type of feed had a significant effect (P <0.05) on feed consumption, body weight gain, feed conversion and crude protein digestibility. The conclusions from the results of the study that growth performance (consumption, weight gain, feed conversion) and nutrient digestibilityies (crude protein and crude fat) were not significantly affected by interactions between types of chickens with feed types. Chicken species did not significantly affect the growth performance and protein digestibility, but fat digestibility differed significantly between local chicken (42.53%) and super local chicken (33.53%). The type of feed significantly affects growth performance and protein digestibilitis. But it is not significant in fat digestibility. The highest protein digestibility was found in the treatment of P3 (88.67%) and the highest fat digestibility, that is in the treatment of factory feed (P1) of (40.71%).
