Most of the urban pollution is the result of carbon dioxide (CO2) emission from human activities. This research identified CO2 emission and absorption in Bogor, and also the alternatives to solve the emission problem by system model and simulation. CO2 emission and absorption system model was created using software Stella 9.0.2 based on loss-gain emission concept for 30 years prediction. Human activities that contribute to CO2 emission are transportation, industries, energy consumption such as fuel or electricity, house hold waste, and farms, while the decrease factor is green open spaces as CO2 sequester. The alternatives to solve emission problem in Bogor is created based on green city concept by including the environmental aspects in every urban activity. The result of this research, the CO2 emission of Bogor reached 20.027.878 tons and the absorption reached 93.843 tons in 2042. Combined mitigation alternatives in several sectors could reduce CO2 emission by 2.797.667 tons in 2042 and CO2 emission could be neutralized by reforestation in 2036.

This study aimed to assess the aquatic carrying capacity for extensive fishing. The study was conducted in Cilala Lake, Jampang Village, Bogor. The carrying capacity was determined based on primary productivity using the chlorophyll value, which is indicating the existence of phosphate in waters. The result showed that carrying capacity of Cilala Lake for extensive fishing was 3.51 tons/year. Tilapia was the fish which could be restocked, because it has high tolerance to waters condition and there’s not prey or predator for this fish. If fish for restocking was assumed about 25 g in size and would be about 250 g after 46 months (harvest size), then the maximum stocked was 15.602 fingerlings/year for two periods. The number of fish pen cage available on the lake should be considered in calculating the number of fish for restocking.

Cilacap 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.

This 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.

Madura cattle is one of the Indonesian local cattle breeds derived from crossing between Zebu cattle (Bos indicus) and banteng (Bos javanicus). Branched-chain α-ketoacid dehydrogenase (BCKDH) is one of the main enzyme complexes in the inner mitochondrial membrane that metabolizes branched chain amino acid (BCAA), ie valine, leucine, and isoleucine. The diversity of the nucleotide sequences of the genes largely determine the efficiency of enzyme encoded. This paper aimed to determine the nucleotide variation contained in section intron 7, exon 8, and intron 8 genes BCKDHA on Madura cattle. This study was conducted on three Madura cattle that used as bull race (karapan), beauty contest (sonok), and beef cattle. The analysis showed that the variation in intron higher than occurred in the exon. Simultaneous indel found at base position 34 and 68 in sonok cattle. In addition, the C266T variant found in beef cattle. These variants do not cause significant changes in amino acids. There was no specific mutation in intron 7, exon 8, and intron 8 were found in Madura cattle designation. This indicated the absence of differentiation Madura cattle designation of selection pressure of BCKDHA gene.
