Abstract

Plantlets of oil palm (Elaeis guineensis Jacq.) derived from so-matic embryos sometimes do not form well developed-roots. Root formation of unrooted-plantlets can be induced with aux-in during ex vitro acclimatization period to simplify the proce-dure and to reduce seedling production cost. Experiments were conducted using a completely randomized design to determine the effect of different types of auxin, i.e. indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), and 1-naphthalene-acetic acid (NAA) at different concentrations, i.e. 0, 2, 4, 8, and 16 mM on root development of oil palm plantlets. The plantlets used were derived from somatic embryos of MK 649 oil palm clone. The basal end of the shoots was dipped in auxin solution for 10 minutes before the shoot was cultured in a small plastic pot containing a mixed growing medium. The cultures were then placed inside a closed transparent plastic tunnel (240 cm x 100 cm x 95 cm) for 12 weeks. The results showed that without auxin treatment only 15% of the shoots formed roots. Dipping in auxin solution increased significantly root frequen-cy to more than 50%. The best root formation was found on the shoots treated with 2 mM NAA by which rooting frequency was 80%. Auxin treatments also increased root quality as indi-cated by more number of primary and secondary roots. IAA, IBA, and NAA treatments at all concentrations tested increased significantly shoot height on average by 42% and shoot diame-ter by 30% compared to control treatment, but did not influ-ence root length. The best treatment for inducing roots of oil palm plantlets ex vitro was by dipping the basal end of the plant-lets in 2 mM NAA solution. The result showed that rooting of oil palm plantlets could be successfully conducted ex vitro that would eliminate sterile rooting stage thus simplify the protocol and reduce seedling production time and cost.

Abstract

Osteomyelitis is heterogenous in its pathophysiology, clinical presentation, and management. Osteomyelitis is generally categorized as acute or chronic based on histopathologic findings, rather than duration of the infection. Necrotic bone ispresent in chronic osteo-myelitis, and symptoms may not occur until six weeks after the onset of infection.1 Epidemiology of chronic osteomyelitis is less well characterized compared with acute osteomyelitis. Adult osteomyelitis most commonly arisesfrom open fractures, diabetic foot infections, or the surgical treatment of closed injuries. Hematogenous  osteomyelitis accounts for approximately 20% of cases of osteomyelitis in adults. It is more common in males regardless of age. Although rare in adults,it most frequently involves the vertebral bodies.2 S.aureus is the most common isolate in all types of bone infection and is implicated in 50-70% of cases of chronic osteomyelitis.3

Abstract

Setiap garis pantai yang didapatkan dari foto udara atau citra satelit adalah garis aktual atau temporal, yang dipengaruhi oleh fenomena pasang surut (pasut). Pada sebuah peta, diperlukan tinggi garis pantai muka laut rata-rata, yang harus dicari dengan bantuan data pasut. Di paper ini, penulis mencoba mendapatkan garis pantai muka laut rata-rata dari citra multi pasut. Hasilnya adalah garis pantai rata-rata dengan akurasi vertikal desimeter sedang akurasi horisontalnya tergantung kelandaian (slope) pantai yang bersangkutan. Penggunaan citra radar lebih mudah sebab citra radar multipasut dengan perbedaan ekstrim lebih mudah diperoleh karena tidak ada kendala awan. Kombinasi metode DEM dan metode median line pada citra radar akan menghasilkan hasil yang nyaris berimpit, sedang pada citra optik, hasilnya akan cukup jauh.Kata Kunci: Garis Pantai, Pasang Surut, Muka Laut Rata-RataABSTRACTAny coastline extracted from aerial or satellite imageries is an actual or temporal line, influenced by tidal phenomena. Mean sea level coastline is needed on a map, which must be extracted with the help of tidal data. In this paper we tried to extract the mean sea level coastline from multi-tidal-imageries. The result was mean sea level coastlines with vertical accuration in decimeter level, while the horizontal accuration depending on slope of the coast. The used of radar data for extracting coastline is easier because the multi-tidal radar images with extreme tidal differences can be obtained since radar data is free of cloud cover problem. Combination method of DEM and median line on radar data would result on a nearly similar coastline.Keywords: Coastline, Tidal, Mean Sea Level

Abstract

Kabupaten Lombok Barat merupakan salah satu Kabupaten di Provinsi Nusa Tenggara Barat yang mempunyai posisi sangat strategis sebagai Daerah Tujuan Wisata (DTW). Disamping keberadaannya sebagai daerah wisata, Kabupaten Lombok Barat juga termasuk daerah rawan bencana, diantaranya bencana tsunami, banjir dan longsor. Untuk itu, diperlukan pendekatan manajemen risiko bencana dalam kerangka pariwisata untuk mendukung Pengurangan Risiko Bencana. Penelitian ini bertujuan untuk memetakan risiko bencana di daerah pariwisata serta memperkirakan kerugian ekonomi yang mungkin timbul bila terjadi bencana. Metode yang digunakan adalah melalui Focus Group Discussion (FGD), pengumpulan data primer dan sekunder serta analisis SIG untuk menghasilkan risiko bencana. Selanjutnya, diharapkan dari hasil penelitian ini dapat digunakan sebagai masukan kepada pemerintah dan masyarakat yang bergerak di sektor pariwisata dalam rangka pengurangan risiko bencana di lokasi penelitian.Kata Kunci: Risiko Bencana, Pariwisata, Focus Group Discussion ABSTRACTWest Lombok Regency is one of regencies in West Nusa Tenggara which become the Tourism Destination Region (TDR). In addition to its presence as a tourism destination area, West Lombok is also categorized as disaster-prone areas, such as tsunami, flood and landslide. Therefore, a disaster risk management approach within a framework of tourism to support Disaster Risk Reduction is needed. The aim of this paper is mapping the risk in tourism area and estimates the economic lose due to disaaster. The method used is a Focus Group Discussion (FGD), primary and secondary data collection and GIS analysis to produce the risk maps. Furthermore, it is expected that the results of this study can be used as input to the government and the people engaged in the tourism sector in the context of disaster risk reduction at the sites.Keywords: Disaster Risk, Tourism, Focus Group Discussion

Abstract

The mining environment is a place to work with a high level of risk. One of the factors that cause work accidents in the mining area is work fatigue or work fatigue. The purpose of this study was to reveal the role of sleep quality as a mediator of the relationship between workload and work fatigue in mining workers in Indonesia. Research participants were mining workers who worked in the field with a 12-hour / day shift work system (n = 232). Measurements were made using 3 scales, namely Full Time Equivalent (FTE) for workload, Pittsburgh Sleep Quality Index (PSQI) for sleep quality, and Three-Dimensional Work Fatigue Inventory (3D-WFI) for work fatigue. The results of the analysis using bootstrapping 5000 showed that workload has a significant effect on the level of work fatigue which is mediated by sleep quality. High workload results in poor sleep quality and high levels of fatigue so that mining companies need to maintain the quality of sleep for field workers to minimize work accidents due to work fatigue.
