Perbandingan Kelimpahan Larva Chironomidae di Dua Danau Berbeda di Provinsi Jambi
Get PDFThis research was conducted at two different lakes in Jambi Province (Lake Sipin and Lake Teluk) to compare abundance of aquatic insect larvae (family: Chironomidae). Lake Sipin located close by the settlement and got many influences from anthropogenic activities. However, Lake Teluk got less anthropogenic disturbance. Both lakes have difference plants cover. The area around Lake Sipin was more open compared to Lake Teluk and it caused low transparency level in Lake Sipin. The transparency level of Lake Sipin was 58.62 cm whereas transparency level of Lake Teluk was 70.29 cm. The difference of this transparency level influenced Chironomidae Larvae abundance that was encountered. Larvae abundance which was found in Lake Sipin was 49 ind/m2, while larvae abundance of Lake Teluk was 374 ind/m2. The result showed that water transparency level, water colors and vegetation affected abundance of Chironomidae larvae

Rasio Panjang-Lebar Karapas, Pola Pertumbuhan, Faktor Kondisi, dan Faktor Kondisi Relatif Kepiting Pasir (Hippa adactyla) di Pantai Berpasir Cilacap dan Kebumen
Get PDFCilacap and Kebumen are potential coastal habitat for mole crab such as Hippa adactyla. Ecosystems condition of both locations is distinct. Each organism have to develop adaptation strategy to deal with environmental variation. H. adactyla usually burry into substrate to cope with environmental stress. They have been adapted to local habitat in order to be able for survive and reproduce. However, it has not been well known whether the adaptation strategy may vary the performance of morphology. This study focused on morphological variation of mole crab H. Adactyla. The sample was carried out on August 2014. Mole crabs were caught using traditional fishing gear called “sorok”. They were 118 individuals which where caught in Cilacap, while 102 individuals that were found in Kebumen. The result showed that H. adactyla walk vertically (backwards). These caused by carapace length and carapace width ratio. T-student analysis showed that relative growth for males were negatively allometric and isometric for female in both habitat. Mean of condition factor (K) for males in Cilacap was 0.0319 ± 0.0025 and 0.0315 ± 0.0028 in Kebumen. Those were significantly higher for females (p<0.05) in Cilacap (0.0325 ± 0.0050) and Kebumen (0.0329 ± 0.0027). Mean of relative condition factor (Kn) was higher in Cilacap for males and females. Those variations of K and Kn related to exogenous and endogenous factors
Kualitas Air dan Status Kesuburan Perairan Waduk Sempor, Kebumen
Get PDFSempor Reservoir is one of the reservoir in Central Java. This reservoir has primary function as irrigation and hydropower source. Beside, it also has some benefit for fisheries and tourism activities. Reservoir utilization which has not been optimum yet need some adjustments with water quality and aquatic trophic state in Sempor Reservoir. This study was aimed to determine water quality and aquatic trophic state of Sempor Reservoir. This study was conducted from January to March 2014 with monthly water sampling. Survey method to collect data with stratified random sampling was used for four represented station. Aquatic trophic state determination was based in Carlson Trophic State Index (TSI) measurement. This method used some represented parameters of physics, chemistry and biology such as water transparency, total phosphorus, and chlorophyll-a. The results showed that water quality of Sempor Reservoir was still good for fishery activities. Aquatic trophic state of Sempor Reservoir based on Carlson TSI was classified to low-medium in euthropic category ranging from 50.71-64.91. Inlet was the only area which had medium category of eutrophic due to highly nutrient content derived from anthropogenic activities nearby
Faktor Risiko dan Prevalensi Infeksi Toxocara vitulorum pada Sapi Potong di Kecamatan Kasiman, Kabupaten Bojonegoro
Get PDFThis study were conducted to determine the presence of toxocariosis in beef cattle in Kasiman Subdistrict, the Regency of Bojonegoro kept under the Sekolah Peternakan Rakyat (SPR) programme. The experiment were done to identify several risk factors that may play certain roles on the degree of prevalence and infection intensity. A total of 263 head of local beef cattle with various ages were taken for faecal samples and 80 farmers were interviewed. Results of the experiment indicated the prevalence of toxocariosis was 5.32% (CI 95% = 2.61-8.04%) influenced by age and gender which showed an effect on the risk of infection. The prevalence tends to decline by age group (p <0.001): calves under 6 months of age (23.68%), and between 6-12 months of age (7.41%), 1-2 years old calves (2.04%) and the above 2 years adults (1.34%). The prevalence is higher in the males group (12.7%) compared to the females group (3.0%), (p=0.003). Logistic regression analysis concluded that age was the only affecting variable to the rate of infection with mathematical models for toxocariosis. Logit toxocariosis = -0.058 -1.098 age.
