Abstract

A study was undertaken on eight farmer groups at Poso District. The aim of the study was to evaluate the pattern growth of goat population given as a government support. The study was conducted for 2 months from July to September 2010. This study was consisted of a survey and direct interview with the goat farmers. Investigated variables were: a) livestock composition at initial population (adult male and female); and at the present time (adult male and female, young goat (>6 months old) and kits, b) rearing management for goat development such as breeding method, mating age, weaning age and birth interval to each of the involved farmer groups. In addition, other considered aspects were housing type, feeds and feeding interval and diseases. Results of the study indicated that: 1) technical coefficient of reproduction such as, weaning age, mating age, birth interval and breeding method did not follow the existing recommended technique on livestock reproduction, therefore the expected growth pattern of the goat population was not achieved; 2) housing system was good enough, only two groups (25%) of the 8 farmer groups has still used soil ground floor and the remaining 75% used stable stage; 3) all the farmer groups experienced with various (4-7) feedstuffs and different feeding intervals and techniques (1.5 – 2 times /day); and 4) high diseases invasion due possibly to feed availability, both qualitatively and quantitavely. Key words : Coefficient of reproduction technigue, operational management, and productivity.

Abstract

Sea grass bed is an important ecosystem in coastal areas and small islands which plays important and effective roles as a protector of the coastal line and the safety of the mainland area of small islands. Physically, the roles of ecosystem were as erosion prevention, sediment trap and barrier of waves and currents. The existence of these ecosystems in the coastal regions and small islands was an important in enhancing the adaptive capacity of islands against natural disaster because the island serves as a natural protector. The aim of this research was to calculate and assess tha adaptive capacity of sea grass ecosystems growing in the waters of around the small islands in the group of Guraici. The research was conducted on 17 islands located in the group of Guraici islands. Measurement of adaptive capacity of sea grass ecosystem was done by analyzing 6 parameters, namely: Sea Grass Dimension Index (IDLn), Dominant Species of Sea Grass, Sea Grass Coverage Percentage (%), Number of Sea Grass Species, Substrate Type, Distance from The Point of Ecosystem. Sea Grass ecosystem adaptive capacity value was in the range between 0.0-1.0, with capacity of five categories of “very low, low, medium, high and very high”. These results indicated that sea grass ecosystem growing in the waters of around the islands in the island of group Guraici had adaptive capacity with values ranging between 0.0-0.59. The ranges of values were distributed into three categories of the adaptive capacities (very low, low and medium). A total of 13 islands had a capacity of sea grass ecosystem “medium”, the other three islands with capacity of “low” and one island with a capacity of “very low”.    Key words : Adaptive Capacity, seagrass ecosystem.

Abstract

Mangrove ecosystem has many functions for coastal area, such as, functions of ecology, social and economic. These functions lead to systemic impact toward other coastal ecosystem environment and human life. Through mitigation, this function can be optimized to minimize the degradation of small island environment. This research analyzed the existing condition of mangrove ecosystem, vulnerability of small islands, and also pattern and management strategy of mitigation based on mangrove ecosystem. This research used both primary and secondary data. Primary data was gathered by sampling field observation, questioner, open interview and in-depth interview in the research area. Secondary data was gathered by literature review and from related institutions. Vulnerability index was analyzed using multi dimensional scaling method whereas vulnerability mapping was analyzed by analysis of geographic information system using the software Archieve Project 3.3. The results of this research was the mangrove ecosystem of small islands in Taman Nasional Bunaken needs to be better managing, considering the increasing rate of degradation and threats to these ecosystems. Nain Island was the most vulnerable island toward the threat of damaging ecosystems by human activities and natural factors. Management scheme which can accommodate a variety of problems faced by the mangrove ecosystems of small islands was collaborative management by the government as the leading sector with the highest priority on the management of the ecological dimension. Key words : Management, mangrove ecosystem, small island, vulnerability.

Abstract

This study aims to find out follicular development and hormone profiles post partum Simmental-Ongole cross cattle (SimPO) with legume phytoestrogen supplementation. Research was carried out since April to December 2010 at pens of Laboratory of Animal Production, Faculty of Animal Husbandry, Gadjah Mada University. A total of 15 SimPO post calving were used and distributed into three treatment groups, namely: PO treatment or control (only fed with the standard), PI : PO + 5 g phytoestrogen and PII: PO + 10 g phytoestrogen. Supplementation of phytoestrogen was derived from soy straw. The parameters were estrogen and progesterone profiles and follicle growth dynamic of post partum. The results of this study indicated that supplementation with 5 g phytoestrogen was more significant in affecting the increase in estrogen and progesterone concentrations, compared with the supplementation with 10 g phytoestrogen and control. Ovarian activity characterized by the development of follicles the SimPO began on day 4 post partum for all treatments but only PII treatments indicated that the development of follicles reached the de Graaf follicle with estrogen concentration of 17,801 pg/ml. Key words : Development, estrogen, follicle, legume, phytoestrogen, progesteron.
