One of the solutions to increase the community welfare and manage the forest is by giving the Social Forestry license. The implementation of community forest intend to give space for the local community for sustainable forest management. The submission of HKm license was done by farmers of HKm group who already received facilitaties from forestry partner that is Non-govermental Forestry Extension Worker (PKSM) to regent. The objectives of this research were to analyze the role of PKSM level for assisting farmer to obtain HKm license and analyze the correlation between external and internal factors of partner with their role. This research was done in Subdistrict Sendang Agung as an area under the jurisdiction of PKSM to assist submission of HKm license. The data was analized by Chi Square test, meanwhile to detect the correlation level of respondent factors with partner role is using coefficient contingency correlation analize. Based on analize result partner role level is obtained in high classification, partner role is as dynamist, mediator, facilitator, motivator, and educators. Internal factors companion that has a strong enough relationship with the role of companion is the number of dependents, long-serving, and cosmopilitaness, where as age, income, as well as information disclosure had uneasy relations. External factors companion that has a strong relationship with the companion role is recognition of the success and intensity of supervision, facilities have less close relationship level with the role of companion. Keywords: coefficient contingency, HKm, role of PKSM

Venu Island Wildlife areas, Kaimana, West Papua is one of the places for nesting of Chelonia mydas, Linn. 1758 (Green Turtles) or local name is Jelepi (Koiway tribe). This study was conducted to identify the physical characteristics of the nesting green turtle in the Venu Island Wildlife Areas, Kaimana, West Papua. Based on the principal components analysis of the nesting green turtle were found that temperature sand at depth ≤30 cm (X ̅=27.42 C ± stdev 0,47 C), lighting at 11.00─13.00 (X ̅=229.25 lux ± stdev 326.50 lux), building areas (X ̅=3.18 m2 ± stdev 16,74 m2), and medium sand fraction in depth ≤30 cm (X ̅=39.86 ± stdev 16.11) as the main factors for nesting and landing of green turtles. On the other hand, mean of the number of nesting green turtle on each sub-plot (X ̅=1.52 nest ± stdev 1.12 nest). Keywords: Chelonia mydas, nesting site, physical characteristic, Venu island wildlife area

Establishment of Marine Protected Area Sukabumi once the backup area Pangumbahan as Turtle Beach Coastal Conservation Areas and Small Islands (KKP3K), directly or indirectly, in desperate need of local community participation in the management of the region. Public perception of environmental conservation activities in the region is expected to help better management activities in the marine conservation area. The results of the analysis of the validity and reliability of the indicator variables assessed showed that each variable has a value Corrected Item-Total Correlation greater than 0.300. While the reliability value is greater than 0.700, i.e. 0.827 (perception), 0.897 (participation), 0.894 (law enforcement), 0.858 (policy), and 0.846 for the variable management. Based on the analysis of variables concluded that the perception of stakeholders and local government policies related Pangumbahan Turtle Conservation Area is the most dominant variable in determining the success of the conservation area management.

Buaya River is one of the river in Bunyu Island which is found near with domestic and agricultural activities. Moreover, Buaya River is also used for fisheries activity by people nearby (fish products collecting and processing) and also used by the fisherman as the back of the boat. These activities will influence and change water quality. This research aimed to analysed water quality condition at Buaya River. Water quality assessment was conducted at four observation station. Water quality was analysed using Storet index and was compared with threshold for marine organisms (Kepmen No. 51/MENLH/2004). The result showed that Buaya River had been polluted at medium level at tide and medium to heavy level at low tide. TSS, oil and grease were not suitable with marine organisms threshold at all stations in low high and low tide. Keywords: Buaya River, tidal, water quality

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. Keywords: carrying capacity, Cilala lake, extensive fishing, pen cage

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. Keywords: condition factor, Hippa adactyla, relative condition factor, relative growth
