Judul: Faktor-faktor yang mempengaruhi kesempatan kerja pada penduduk di desa dalam perkebunan kelapa sawit (kasus desa Cimulang dan desa Bantar Sari, kecamatan Rancabungur, kabupaten Bogor, provinsi Jawa Barat)
Abstrak: Oilpalm is one of Indonesia’s agricultural commodities with rapid growth in the last two decades – annually size of plantation increased by 11% whereas production by 9.4%. One of the objective of oilpalm development is to generate employment opportunity – which is expected to be captured by community surrounding oilpalm plantation. This research is to describe and analyze employment opportunity by sectors (foodcrops-fisheries, plantation, secondary/manufacture, and tertiary/trade and services) and the internal and external factors that affect employment opportunity. Cimulang and Bantarsari are two villages in West Java with 75% of its area inside a state-owned plantation, which undergone conversion from rubber to oilpalm in the year 2000. The research is done on 4 hamlets of these villages differentiated by geographical location and transportation access into two (2) Kampung Dalam which are inside plantation-area and limited transportation access and two (2) Kampung Luar which most area are outside plantation and easy transportation access. The research indicated that all of the internal factors (gender, age, education, social status), affect employment opportunities. In general more men works in different sectors than women, and more workers (of young age group, higher education, and high social status) work in tertiary sector. Only a small percentage work in oilpalm plantation, and only those from Kampung Dalam, male, of medium age-group, with some education (Elementary, Junior High), and of poor social status. Of the external factors (access to information of job, access of transportation), access to information affect employment opportunities in secondary and tertiary sectors. As the difference of employment opportunity seems to be more based on location (Kampung Dalam or Kampung Luar), which is indicated by access to transportation, access of transportation is seen as mediating factor that affect both internal and external factors.

Judul: A Study of Oil Palm Plantation in Sukabumi Regency: Land Suitability and Socio-Economic Approach
Abstrak: The increase of the world oil palm demand, encourage Indonesia to develop oilm palm industry both of expansion and conversion. Commodity crop conversion can be interpreted as a change in the cropping system from one crop commodity to another. As happened in Sukabumi Regency, West Java, commodity crops have been converted from rubber and tea to oil palm on state-owned plantation land. This research analyzes land suitability and consistency, social conditions, and the standard of living of oil palm plantation workers in the Sukabumi Regency. The data used in this study are primary data and secondary data. The method used is the visual interpretation of satellite imagery, overlay, table matching using ArcGIS, and different tests using SPSS software from the results of interviews with respondents using a questionnaire. The results show that the percentage of land area converted to commodity crops from rubber and tea to oil palm continued to be massive from 2002 to 2020. The conversion was made because the selling price of the previous commodity continued to fall. The land suitability level of state-owned oil palm plantations in Sukabumi Regency is dominated by category S3. 95% of oil palm plantations in Sukabumi Regency are following the 2011-2032 Sukabumi Regency spatial planning. The conversion of commodity crops from rubber and tea to palm oil has a positive impact on improving the social conditions and the standard of living of oil palm plantation workers. The eight recommendations are prepared based on an analysis of land suitability and consistency of land use with spatial plans. Other recommendations given are based on the social conditions and standard of living of plantation workers. It is hoped that this will form an independent local workers' association to increase the gaining power to demand justice, rights and proper welfare for workers and their families. In addition, the existence of associations can also mutually control the performance of workers in carrying out their obligations.

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.
