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

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.

Abstract

Inadequate latrine and water source cause transmission of intestinal parasitic infection, particularly in children. There is a lack information about it and it is needed to be investigated. This study aimed to compare the prevalence of intestinal parasitic infection, the use of latrine and clean water source in elementary school children at coastal and non-coastal areas in Sumenep District, Indonesia. An analytic observational study with cross sectional design was conducted in Dasuk Timur Elementary School located at coastal area, and Kolor II Elementary School at non-coastal area, Sumenep district, in January 2020. Intestinal parasites in students' stools were identified by microscopic examination using wet direct smear stained with lugol. The use of latrine and water sources were analyzed with questionnaire. A total of 68 children stools were collected from both elementary schools. Worm infections were not found. Thirty-one children (31/44, 70.5%) from Dasuk Timur Elementary School and eight children (8/24, 33.3%) from Kolor II Elementary School were infected with intestinal protozoan and significant difference (P=0.003, Chi-square test). Blastocystis hominis was highly found in stools of Dasuk Timur Elementary School's students (31/44, 70.5%) and significantly different from Kolor II Elementary School's students (P<0.0001, Chi-square test). Three children (3/44, 6.8%) from Dasuk Timur Elementary School were still practicing open defecation. Dasuk Timur Elementary School's students suffered from intestinal parasitic infection were mostly using non-piped water source (20/31, 64.5%) and were significantly different between two elementary schools (P=0.015, Fisher's exact test). Prevalence of intestinal parasitic infections in children was found higher in coastal than non-coastal area due to the commonly use of unclean water sources and inadequate latrine.

Abstract

This study investigates the role of multifaceted job satisfaction as an antecedent variable and moderating factor influencing work engagement in the public sector. Drawing upon Bakker and Demerouti's (2007) model, the research adapts Spector's (1997) job satisfaction measurement constructs and tests them on a sample of 1484 employees. Employing a mixed-methods approach with a cross-sectional design, the study focuses on identifying key drivers of work engagement in the aftermath of the COVID-19 pandemic. All dimensions are constructed based on qualitative exploration through Focus Group Discussions (FGD) involving 122 respondents, and item formulation is guided by the mapping of dimensions using In-Vivo software. The study employs bootstrapping techniques, revealing a Structural Equation Modeling (SEM) result with a Standardized Root Mean Residual (SRMR) value of 0.054 (<0.08), indicating a perfect fit for the model. All path coefficient indices exhibit a P-Value of 0.000 (<0.05), signifying the acceptance of all proposed relationships in the study. The findings contribute to understanding the intricate interplay between job satisfaction, personal factors, organizational factors, and work engagement, providing valuable insights for practitioners and policymakers in the public sector post-COVID-19.

Abstract

Praktik manajemen sumber daya manusia (SDM) dapat memberikan dampak yang besar seberapa baik kinerja karyawan dalam aspek kinerja dalam peran dan ekstra peran. Dampak dari berbagai metode MSDM, khususnya digitalisasi praktik MSDM, terhadap kinerja in-role dan extra-role karyawan yang bekerja di bisnis garmen jadi belum diteliti di Bangladesh. Oleh karena itu, tujuan utama penelitian ini adalah untuk menyelidiki dampak digitalisasi manajemen sumber daya manusia terhadap kinerja karyawan dalam peran dan peran ekstra dalam konteks perusahaan garmen jadi (RMG) di Bangladesh. Menggunakan 25th versi Paket Statistik untuk Ilmu Sosial (SPSS), penelitian ini menyelidiki pendapat karyawan yang bekerja di berbagai departemen perusahaan RMG di Bangladesh. Hal ini bertujuan untuk menentukan bagaimana praktik MSDM tertentu terdigitalisasi, khususnya rekrutmen dan seleksi elektronik, pelatihan dan pengembangan elektronik, penilaian dan manajemen kinerja elektronik, manajemen kompensasi elektronik, manajemen pengaduan elektronik, manajemen komunikasi elektronik, manajemen karir elektronik, dan lain-lain, berdampak terhadap kinerja pegawai in-role dan extra-role. Temuan penelitian ini menunjukkan bahwa, meskipun praktik MSDM digital tertentu seperti manajemen kompensasi elektronik dan karier elektronik berdampak signifikan terhadap kinerja peran-ekstra karyawan, namun kontribusinya tidak signifikan terhadap kinerja karyawan, kinerja peran. Selain itu, ditemukan bahwa manajemen penilaian kinerja elektronik mempunyai dampak positif yang signifikan terhadap kinerja dalam-peran karyawan. Studi ini juga berupaya menyarankan badan manajemen perusahaan RMG untuk mendigitalkan beberapa prosedur HRM yang dapat meningkatkan kinerja karyawan dan organisasi.
