Abstract

One of the major problem for fishermen of Tolo Bay water in optimizing the utilization of the fish resources is the difficulty in determining potential fishing grounds. The fishing area is very much determined by the distribution of oceanographic parameters, in particular the distribution of sea surface temperature and chlorophyll-a concentration. The aim of the reaserch is to estimate the fishing ground using integrated sea surface temperature and chlorophyll-a distribution image data from Aqua-Modis Level 3 Satellite and Seades 7.2. The Reseacrh was conducted using GIS-based Remote Sensing Method and Field Survey through in situ measurement (ground check) as validation data. Satellite image data in the form of sea surface temperature distribution and cholorophyll-a were analyzed using ArgGIS 10.2 software. Recorder sea surface temperature and cholorophyll-a image data were obtained from National Institute Of Aeronautics and Space (LAPAN) as well as data from observations at 10 station. The results of research on estimating potential fishing ground in the water of Tolo Bay based on the distribution of sea surface temperature and cholorophyll-a concertractions are integrated in the fishing ground zoning in July with nine coordinate points.

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

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.
