Judul: Regional Development Plan Based on Beekeeping Activity in Cianjur Regency
Abstrak: Forestry development policy-based natural resources provide benefits to the development of non-timber forest products through social forestry activities, including beekeeping business. Beekeeping businesses have considerable opportunities to be developed in the community. It is because of the demand of honey is increasing for variety of needs. Furthermore, Indonesia also has the potential of natural resources to support the beekeeping development business. One of the potential areas for beekeeping development is Cianjur Regency, where it has been cultivated since 2006. The type of honey bee which cultivated is Apis mellifera, with an average production of 3-4 tons/year. However, the main problem encountered beekeeping activities in this regency is limited bee forage resources. This limitation and migratory behaviour of Apis mellifera are causing herding activity of the bees in certain months must be herded out of Cianjur to increase honey production. As an effort to overcome this problem, Cianjur Regency Government through the Forestry and Plantation Agency has been developing a Participatory Business Plan (PBP) to build a Tourism Bees Park. The basic concept of PBP is implementing an integrated beekeeping, through the development of bee forage resources, honey bee product processing and diversification of honey bee product in one location without herding activity outside Cianjur. Geographic information systems (GIS) have the ability to create a model framework for land suitability evaluation (Elsheikh et al. 2013) and develop habitat suitability models through a multi-criteria evaluation approach and integrate it with expert knowledge (Store and Jokimaki 2003). GIS approach is applied in this research to determine the land suitability for beekeeping. Moreover, through the analysis of land suitability for beekeeping by considering physical, social and financial aspect, this research is expected to provide direction plan for integrated beekeeping development in Cianjur. The objectives of this research are: (1) to analyze the beekeeping land suitability, considering the land suitability for bee forage plants and the habitat suitability for honey bee; (2) to analyze beekeeping financial; (3) to analyze public opinion about beekeeping, and (4) to formulate the development plan based on beekeeping activity. The selection of bee forage plants in this research are based on the time of flowering, pollen or nectar production, deployment, advantages and disadvantages in terms of cultivation. In this study, land suitability classification use the FAO (1976) clasification, which is not suitable order (N) just using 1 class. These consist of 4 classess: very suitable (S1), suitable (S2), marginally suitable (S3), and not suitable (N). The results of land suitability analysis for bee forage resources indicate that the land suitability classes for kapok S3 and N, while rubber and rambutan have suitability classes S1, S2, S3 and N. In addition, land suitability classes for corn consists of S3 and N; kelengkeng S2, S3 and N; Calliandra has suitability classes S and N. Each land unit has a variety of combinations of land suitability classes, which are 2-6 types of suitable bee forage resources per land unit. The percentage of Cianjur Regency area that very suitable to be used as a honey bee habitat is 22.94 % (83,030 ha), 33.44 % (121,034 ha)

Judul: Feed Source Potential Plants to Carrying Capacity Beekeeping Habitat (Apis dorsata) in Belitung District
Abstrak: Apis dorsata bee is one species of bee that produces honey. This species cannot be separated from the availability of plants that serve as a source of feed, namely nectar and pollen. The higher the potential of bee feed, the more bees produce honey because of the large availability of feed. These factors have the most important value in the carrying capacity of Apis dorsata bees. The development of the beekeeping business in the Belitung Regency causes an increase in the bee population, which will negatively impact if it is not accompanied by the availability of plant habitat as a source of feed. Therefore, information about the distribution pattern, abundance, and diversity of pollen and nectar-producing plants in the Belitung Regency needs to be known. Based on this background, this study aims to identify the composition, diversity, spatial distribution patterns, plant associations, influential environmental variables, and the potential area of nectar and pollen-producing plants as the carrying capacity of A. dorsata habitat. The diversity of plant species that produce nectar and pollen data was obtained from farmer information and direct observations. The spatial distribution pattern of nectar and pollen-producing plants and vegetation analysis using the purposive sampling method. Observation of the composition structure of the Apis dorsata habitat was made using a combination of observational plots between the method of pathways and nesting plots. The distance for each transect is 3 km. The profile diagram was created by determining the location in the sunggau group (labun) with a size of 20 × 20 m2 (400 m2 ). Habitat characteristics data is determined based on abiotic environmental factors: air temperature, humidity and light intensity, pH, and soil moisture. The collection of abiotic parameter data was carried out at every single sub-station on four repeats of each transect. Determination of habitat potential using MaxEnt v3.4.0 software using species presence data and environmental variables. The results showed 55 potential plant feed species for Apis dorsata, 40 species of nectar-producing, 40 species of pollen-producing, and 26 species of nectar and pollen-producing species. The level of species diversity (H') in Perpat Village is classified as medium to high with a value of (2.92 - 3.02). Kembiri Village is classified as moderate to high with a value of 2.57 - 3.09. From both locations, the diversity index in Perpat Village is classified as higher in all growth phases. The value of species dominance (C) from both locations in Perpat Village was more dominated by several species than in Kembiri Village. The value of species-level (E) in Perpat Village has a higher value where the higher the value of leveling, the more stable the species diversity in the community. Other research results showed that the association index value in Perpat Village is meager at 36.7% compared to 45.9% in Kembiri Village. Only a tiny percentage showed a very high degree of association in the first location at 18.3% and the second at 12.1%. The distribution of plants in Perpat Village and Kembiri di lokasi pertama sebesar 18,3% dan lokasi kedua sebesar 12,1%. Persebaran tumbuhan di Desa Perpat dan Desa

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
