Judul: Analisis Keberlanjutan dan Keselamatan Kerja Perikanan Panah (Spearfishing) di Kepulauan Karimunjawa
Abstrak: Speargun is a productive fishing gear operated by Karimunjawa fishermen. Spearfishermen face potential conflict with other fishermen and also facing major health risk. Objectives of this research are to identify and describe spearfisheries, determine spearfisheries status based on CCRF perspective, define development strategy, and describe job safety analysis. This research was carried out using survey methods. Spearfishing is one night trip operations, spearfishermen undertake five to six trip a week. Spearfishing operations perform nearly throughout the year. Spearfisheries target fish mostly reef fishes. 65 species caught by spearfishermen, weighted 38,767.9 kg, by effort as many as 582 trips. Average CPUE is 63.27 kg / trip. Spearfisheries viewed from CCRF perspective, not fully support CCRF concept. Biological, technological, and social aspects need to improve. External factors affecting spearfisheries system are political, economic, social, cultural, and technological developments. Those external factors make enough impact on Karimunjawa spearfisheries development. Internal factors include management, human resources, and fish resources. Internal factors conditions are able to overcome various problems in spearfisheries. Spearfishing operations by diving is high risk activities. Spearfisheries operations work steps sequence analyzed its potential hazards / accidents and what prevention measures needs to take to minimize that potential hazards / accidents.

Judul: Fishermen work safety at fishing operation on payang in Palabuhanratu, West Java
Abstrak: The main cause of marine accidents resulting in loss of human lives is purely human error. Specifically on the capture fisheries, as many as 80 percent of marine accidents are caused by factors of human negligence (FAO, 2009). The purpose of this study is to inventory and describe all hazards and possible consequences in every aspect and stage, inventory and identify those aspects related to the management of safety of fishermen, both institutionally, existing regulations, human resources, working conditions and safety design models fishermen work at the sites. Scope of the study was limited to payang fishing activities in fishing operations in Palabuhanratu. The research was conducted in October 2011 - August 2012, in district Palabuhanratu West Java, especially in PPN Palabuhanratu. This research activity was carried out by conducting literature studies and interviews with the aim of collecting primary data in the form of direct observation and interviews/questionnaires to all the components, either directly or indirectly involved. Collection of secondary data fishery, related regulations, journals, and other related literature. Policy and institutional analysis be descriptive. The next method is the Formal Safety Assessment (FSA), the human element can be incorporated into the FSA process using human reliability analysis (HRA). HRA in this study quantitatively. To complete the picture details the development of systems analysis models to understand and make decisions related to SMK3. Activity that has a chance of failure risk was greatest in gear operating activities during setting. Consequences of accidents greatest opportunity in hauling activity. Risk control is done with the selection of a competent crew, plan fishing/sailing, designing safe work procedures, use of equipment as needed, using personal protective equipment and conditioning healthy working environment, as well as coordination among crew always do. Need to restructure relating to the management of fishing safety associated with existing policies and institutions, so that the mutually synergistic implementation. Analysis of the safety management system of the fishermen showed no systemic features and characteristics of the organization who have learning disabilities. (A) Each stakeholder tends to stand in their own point of view or interest. (B) Completion of the problems in safety management fishermen tend gradually, not structured and are regional and do not change the mindset. (C) In the safety management practices on certain aspects (control) often occurs transitional resources for the benefit of others. This transfer shows that the issue of safety management is not a priority fishermen and not something that should be addressed immediately. (D) Aimed of fishing safety management is not up to the level of implementation.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
