Abstract

Traditional healers (shamans or Batra) are people who have local knowledge in concocting plants as medicine to treat diseases suffered by the community. Currently, the number of those who are still practicing traditional medicine is decreasing. The purpose of this study was to document the local knowledge possessed by traditional healers or shamans in Antan Rayan Village, Landak Regency, West Kalimantan. The selection of respondents (traditional healers) was carried out using the snowball method. Respondents were interviewed regarding their local knowledge about the plants used to treat diseases in the Antan Rayan village community, the parts of the plants used, processing and usage methods, and the frequency of use. In Antan Rayan's village, four traditional healers (shaman/battra) still carry out traditional medicine using medicinal plants. From this study, 86 medicinal plant species were documented and included in 31 families, and Lamiaceae was the most commonly used family. These healers use these plants to treat various diseases the villagers suffered. The leaf is the most widely used part of the plant (44%). The most commonly used processing and usage method is boiling (48% and 54%), with the most common frequency being three times a day (45%).

Abstract

Hydrogen is a renewable energy source that can be used as a fuel and as an  alternative to fossil fuels. Solid  storage media in solid form are safer to use than liquid (-253 oC) or gaseous media (700 bar) media. To store hydrogen in a solid medium, it requires a metal able to  interact with hydrogen . Magnesium is one of the metals which  can form metal hybrids based on MgH2 which is capable of  absorbing hydrogen up to  (7.6wt%). However, the reaction kinetics for  magnesium are  very slow, it takes at least 60 minutes to absorb hydrogen and the operating temperature is always  very high (300 oC). Several attempts have been made to add the catalytic converter  and milling time. Hydrogen storage material based on MgH2 with a 10wt%Ni catalyst was  successfully synthesized using a mechanical alloy technique with time variations of 2 hours, 5 hours, and 10 hours. From the results of the X-ray diffraction schema  at a diffraction angle of 2θ=37.87o, it shows the presence of a MgH2 phase, Ni phase is at a diffraction angle of 61.85o, the diffraction peak also shows that there was a  widening of the diffraction peak with increasing milling time, this explains that there was  a reduction in the size of the crystal. When  calculating  with the Schereer method, the crystal size of the material reaches 10 nm. The results of the DSC test indicated  a decrease in temperature of 383 oC in 41 minutes with a milling time of 10 hours.

Abstract

PT XYZ is a potential and growing agro-industry enterprise in Indonesia. This company produces agricultural chemical products. The firm also implements health safety management as a standard operational procedure to create a safe and healthy workplace environment. A fire extinguisher is considered a precautionary tool in case of a fire accident in the workplace. Even though there has never been a fire accident in the workplace that required a fire extinguisher, periodic fire extinguisher inspections are required to be adequately used in an urgent situation. A critical finding during internal HSE audits was that tools performance was not following PERMENAKER 04/MEN/1980. As a result, it is necessary to evaluate the fire extinguisher inspection. This study aims to identify the potential hazards and evaluate current procedures of fire extinguisher inspection using the Job Safety Analysis approach. This study found that the primary hazard is tripping, scratching, and the fire extinguisher falls. Improved work safety can be done by carrying out seven secure steps and identifying prevention procedures for potential hazards during fire extinguiser’s inspection procedures.
