Abstrak: Forestry sector, particularly tree harvesting activity is well known as high work accident risk activity. One of the aspects which tend to be ignored in this activity is workforce asP€?C This ignorance is generally caused by the fact that workforce is still considered as an inpuf ill this business, not as an important capital. Several studies have been conducted in an effoxtto improve the quality of occupational safety and health as well as the regulations and practWaI code to decrease the risk of safety and hea1t11. However" there have been many accid.m. lts occurred in the field, indicated from the high rate of work accidents and work di~s. This trend is increasing from year to year. In line with this, the study was conducted to ~ine the condition of occupational safety and health in forestry by analyzing the wor~s' competency aspects on occupational safety and healrh by the use of competency indicMor: skill,knowledge, and attitude by examine the gap in the competency aspects. An alteJ1l1rtive strategy to lessen the gap and at the same time to decrease the risk of work accidents was jetennined ~ Data were collected was done through a direct observation of facilities and infraSbructures of occupational safety and health in the fieldwork and a direct interview with the resp~dents by ilie use of questionnaires. The respondents were chainsawman, skidding work!r, and log transporting worker which included hauling worker itself and truck driver. Furtle'r, manager of Jaya Lestari Forest Cooperative also has been choosing as respondent. Respar.dents collecting was done by Random Sampling, where samples collecting was very muc~influenced by the condition of research location and work schedule of felling, skidding and ~g transporting. The analysis applied was Likert analysis which was tested by using two methods: Kruskal-Wallis test, and Spearman rank correlation test. Kruskal-Wallis test was used to find out whether there was a similarity in perception between workers and manager of Jaya Lestari Forest Cooperative concerning International Labour Organization (ll..O) standard, while Spearman rank test was used to examine whether the three competency aspects tested (knowledge, skill, and attitude) were interconnected. There was a lacking on knowledge aspec of the manager and field worker of Saya Lestari Cooperative, therefore they were unable to implement and run the tree harvesting activities safely and healilily. This was clearly indicated by the gap between the workers' perception and the manager conceming n.,o standard. Tile gap among the manager appeared in the aspects of knowledge, skill, and attitude. In the meantime, the gap among tree harve~.ting app d in the three competency aspects (knowledge, 0011, and attitude). Finally, the gap betWeen the skidding worker and log transport worker was only related to attitude, and the hi t gap of all kinds of work was attitude. TIle de\'elopment of occupational safety and heal should be started from development of management's commitment which is followed by an ~Pt to disseminate it to all levels including the lowest level of workers as well as co~t workers. hnplementing the commitment means performing a control over workers' perfQD:p.ance in all fields, making sure that all workers

Judul: ompetency Analyze of Application Occupational Safety and Health for Forestry Workers on Timber Harvesting Sector in KPH Bogor Perum Perhutani Unit III West Java and Banten
Abstrak: Pekerjaan di bidang kehutanan, khususnya dalam kegiatan pemanenan kayu (penebangan, penyaradan, dan pengangkutan) merupakan salah satu pekerjaan lapangan yang memiliki resiko pekerjaan tinggi terhadap kondisi keselamatan dan kesehatan kerja berdasarkan tingginya angka kecelakaan yang terjadi. Kurangnya pemahaman pihak perusahaan dan pekerja terhadap pentingnya K3 berdampak pada rendahnya kompetensi penerapan K3 yang meliputi aspek pengetahuan, keterampilan, dan sikap sehingga terjadi kesenjangan antara berbagai peraturan yang telah dibuat oleh pemerintah dengan keadaan sebenarnya di lapangan. Penelitian ini dilakukan untuk menganalisis tingkat kompetensi pekerja pada kegiatan penebangan, penyaradan, dan pengangkutan dengan menguji persepsi pekerja (self assessment) terhadap penilaian objektif yang dilakukan (control based assessment) dan menguji hubungan antar aspek kompetensi pekerja (knowledge, skill, attitude) untuk menentukan aspek kompetensi yang perlu ditingkatkan yang berhubungan erat dalam penyusunan kebijakan K3. Metode penelitian yang digunakan untuk mengumpulkan data yaitu wawancara terstruktur terhadap responden menggunakan kuisioner yang telah ditentukan pilihan jawaban pertanyaan berdasarkan skala Likert dan observasi untuk mengetahui kondisi riil penerapan K3 pada kegiatan pemanenan kayu. Berdasarkan analisis data menggunakan analisis deskriptif terdapat selisih yang bernilai negatif antara persepsi responden dengan penilaian berdasarkan standar yang menunjukkan bahwa persepsi responden overestimate dengan penilaian sesuai standar yang dilakukan. Besarnya selisih yang terdapat pada tiap aspek kompetensi setelah dilakukan uji Wilcoxon menunjukkan terdapat perbedaan yang signifikan antara persepsi responden dengan penilaian sesuai standar. Dari hasil penelitian pada uji korelasi Spearman terdapat hubungan yang signifikan antara aspek kompetensi sehingga perlu peningkatan kompetensi pada aspek pengetahuan, keterampilan, dan sikap kerja untuk masing-masing pekerja pada kegiatan pemanenan kayu.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
