Evaluation of safety and health performance on construction sites (Kuala Lumpur).

Occupational safety and health Act (Act 514) obligate each employer to provide and maintain a safe and healthful workplace for all his employees. Construction is a risky business with a lot of injuries and illness, due to poor safety performances. The aim of the study is to investigate the safety and health performance of contractors on construction sites. A comparative and sensitivity analysis conducted reveal that as allocation to the construction increases so also the rate of accidents increases and that fatal accidents contribute more to the total accidents rates, as such there is need to assess the performance of contractors as regard to safety and health operation. The result of the SHASSIC score reveal that the sites consider for the study were 3 – star in ranking, were its risks/hazards activities are well managed and documented, but still there are other risks/hazards activities that are not taken care off due to negligent on the side of the contractors. The finding affirm the importance of safety program in construction site, as such to ensure successful implementation of the safety program, the following condition must be made; management commitment, safe work condition and safe work habit

Characterization of LUSI Mud as Geopolymer Raw Material

The mud of mud volcano samples were collected from an eruption site named ‘LUSI’ (Lumpur “mud” –Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO2 and Al2O3 which are higher than those in fly ash. The particle of mud has a flake-shaped particle and the overall particle size is dominated by particles between 2.5μm – 25.0μm. The results of XRD shows that mud of mud volcano have a characteristic of structurally disordered compounds, and a set of peaks corresponding to minor crystalline phases such as quartz, feldspars, and kaolinite. FTIR adsorption bands of the raw material of mud have the chemical bonding between bands 1-5

Griffiths phase in diluted magnetic semiconductors

We study the effects of disorder in the vicinity of the ferromagnetic transition in a diluted magnetic semiconductor in the strongly localized regime. We derive an effective polaron Hamiltonian, which leads to the Griffiths phase above the ferromagnetic transition point. The Griffiths-McCoy effects yield non-perturbative contributions to the dynamic susceptibility. We explicitly derive the long-time susceptibility, which has a pseudo-scaling form, with the dynamic critical exponent being expressed through the percolation indices.Comment: 4 pages, final version as publishe

Desain Pembelajaran Fisika Terpadu untuk SMA Berbasis Keunggulan Lokal Pariwisata

Sekolah yang menerapkan kurikulum berbasis keunggulan lokal harus dapat mengolah bahan ajar dan model pembelajaran yang tepat agar integrasi konten keunggulan lokal dapat tersampaikan dengan baik pada semua mata pelajaran, termasuk Fisika. Penelitian ini bertujuan untuk menghasilkan model pembelajaran fisika terpadu bagi sekolah yang menerapkan keunggulan lokal bertemakan pariwisata. Penelitian dilakukan di sekolah yang menerapkan keunggulan lokal pariwisata bahari. Metode penelitian yang digunakan adalah 4D Thiagarajan dengan tahapan: pendefinisian, perancangan, pengembangan, dan penyebarluasan. Produk dari penelitian ini berupa sintaks model pembelajaran fisika terpadu untuk sekolah dengan keunggulan lokal pariwisata dan peta materi ajar fisika terpadu pariwisata bahari. Produk ini telah divalidasi dan diuji coba terbatas dengan hasil model pembelajaran tersebut layak diimplementasikan pada sekolah yang menerapkan pendidikan berbasis keunggulan lokal

Peranan Sistem Repong Damar terhadap Pendapatan, Asupan Makan dan Status Gizi Balita : Studi Kasus di Desa Pahmungan Kecamatan Pesisir Tengah Kabupaten Pesisir Barat

Regions Special Purpose or KDTI (Ministry of Forestry decree No.47/Kpts-II/1998) Repong Damar indigenous forest area of 29,000 ha which is a best practice community-based forest management in the western part of Lampung Province yet known about its capacity to ensure the sustainability of human resource development primarily critical starting at the age of five or its called toddlers. This study was doing from March to April 2014 in the village of Pahmungan District of the West Pesisir. The purpose of this research is: Knowing the linkage between population and income damar tree tenure, household food expenditure, protein intake toddlers, health status and nutritional status of toddlers. Data acquisition was done through interviews to collect data ownership damar tree population, income, food expenditure, health status and food intake (food recall) as the basis for determining the toddler nutritional status of children is calculated by the method of anthropometry (Ministry of Health, 2010). Parameter optimization using the software Minitab 16. The conclusions has proven there is a real link between the role of damar agroforest system to income, health status, and nutritional status of toddlers. Found relations or real relationship between income of damar agroforest [YI] with a population of damar tree with a model [YI]i= -0.1770 +0.023150[PHN]i. Furthermore simultaneously discovered the real relationship between food expenditure (YII) with [YII] as illustrated by the model [YII]i= 1.1546 +0438 [YI]. Further simultaneously discovered the real relationship between protein intake toddlers [YIII] with food expenditure [YII] with the model [YIII]i= 17 012 +3703 [YII]

The Early Iron Age collective tomb LCG-1 at Dibba al-Bayah, Oman: long-distance exchange and cross-cultural interaction

The Iron Age (c. 1300-600 BC) of South-eastern Arabia is characterised by rapid expansion of settlement. Social structures formed over the previous millennia, however, persisted and were reinforced through the development of collective funerary monuments. A recently discovered tomb of Late Bronze to Early Iron Age date at Dibba al-Bayah in the Sultanate of Oman has yielded a range of artefacts that illuminate the nature and extent of the long-distance contacts of the local community. Seemingly selected not only for their exotic appeal, but also for their apotropaic function, these objects testify to a deep cross-cultural knowledge extending across the wider region during this crucial period in Arabian prehistory
