Judul: Ergonomi dalam Aktivitas Penangkapan Ikan di Kapal Pancing Layur di PPN Palabuhanratu, Sukabumi
Abstrak: Hairtail fishing vessel is one of the fishing vessels in Palabuhanratu fishing port with hairtail as the main catches that have high production values. Many fishermen are often absent because they feel tired and experience aches and pain in several parts of their body. Presumably, it is because incorrect posture when fishermen move on vessel, uncomfortable working area and facilities on vessel, or fishermen’s energy imbanlance. Furthermore this research is related to ergonomics and also its derivatives such as biomechanics, anthropometry, and energy balance are expected to design better system on hairtail fishing vessels. The purpose of this research were to analyze hairtail fishermen’s posture when fishing operations occur, to analyze anthropometric data from hairtail fishermen to determine the ideal size of are and facilities on vessel, and also to analyze the correlation between energy intake and energy needs of hairtail fishermen. The method used in this research was a case study method with descriptive data analysis. Posture analayzis showed that there were still about 45 % of 22 hairtail fishermen’s postures which need to be improved. Based on the fishermen’s body anthropometric data, it was found that the right size of seat height was 39,42 cm; table height was 59,7 cm; the minimum widht of table was 33,14 cm; the distance of table from the set was -11,7 cm. Energy balance assesment showed that only 10 % of fishermen of hairtail fishing vessel who met their energy needs.

Judul: Aspek Ergonomi pada Aktivitas Penangkapan Ikan Menggunakan Jaring Tarik Berkantong di Pelabuhan Perikanan Nusantara Brondong
Abstrak: Area kerja yang sempit dan aktivitas diatas kapal yang tidak sesuai prosedur berpotensi menyebABKan cedera otot dan menimbulkan gejala musculoskeletal disosrder (MSDS). Aktivitas tersebut hampir dilakukan setiap hari memengaruhi kesehatan ABK. Tujuan penelitian ini adalah mengidentifikasi risiko dan postur kerja ABK dengan area kerja terbatas dan menganalisis aspek ergonomi ABK jaring tarik berkantong. Data yang dibutuhkan pada penelitian ini adalah data keluhan penyakit pada ABK yang diambil dengan wawancara. Metode yang digunakan adalah metode Workplace Ergonomic Risk Assessment (WERA) dan kuisioner Nordic Boay Map. Hasil penelitian berdasarkan penilaian metode WERA pada sembilan belas aktivitas penangkapan ikan jaring tarik berkantong memeroleh level risiko tinggi sebesar 40 termasuk dalam kategori medium, yaitu aktivitas mengangkat tali selambar, pelampung, dan pemberat secara manual. Mayoritas dari 53 ABK jaring tarik berkantong mengalami tingkat keluhan pertama dibagian bawah pinggang sebesar 51% dan pinggang sebesar 46%, atau yang disebut gejala MDS. Postur kerja ditinjau untuk mengurangi risiko cedera otot dan mencegah terjadinya kecelakaan kerja dengan menggunakan mitigasi risiko pada setiap bagian tubuh saat melakukan aktivitas penangkapan ikan.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
