Abstract

The onions (Allium ascalonicum L.) is one of the horticultural plants that is used as a popular cooking spice and has a layered tuber. Shallots also have benefits in the health sector and have high prospects in the domestic and national market. The high demand for shallots caused by the increase in population so that efforts need to be made to increase productivity. One of the efforts made is the use of varieties that are suitable for the environment and the use of efficient fertilizer doses. This study aims to determine the growth and yield of two local varieties of shallots at various doses of inorganic nitrogen fertilizers and to determine the efficiency of inorganic nitrogen fertilizer doses in the cultivation of several local shallot varieties. The research was carried out at the Experimental Garden of the Faculty of Agriculture and the Laboratory of Agroecotechnology, Faculty of Agriculture, Malikussaleh University from March to May 2021. This study used a 2x4 factorial randomized block design with 3 replications so that there were 24 experimental units and continued with the DMRT test at a level of 5 %. The first factor is the local variety which consists of 2 local varieties, namely V1: Bauji local variety (West Java) and V2: Tajuk local variety (West Java). The second factor is the application of inorganic nitrogen fertilizer with a dose consisting of 4 levels, namely N0: Without Fertilizer N, N1 (13.2 g/plot), N2 (16.8 g/plot) and N3 (20.4 g/plot). Parameters observed were plant height, number of leaves (strands), number of tillers, number of tubers per clump, wet weight of bulbs per clump, wind-dry weight of bulbs per clump, production per plot, and tuber diameter. The Tajuk variety is the best local shallot variety compared to the local Bauji variety and the best dose of inorganic nitrogen fertilizer is at a dose of N1 (13.2 g/plot) and there is an interaction between the number of tubers and the weight of the tubers.

Abstract

Mining operations need to recognize potential hazards, evaluate the risks involved, and continuously control risk to a manageable level. In addition to statistical data, other factors contributing to the rise in industrial accidents in businesses include the effective tunnel temperature, which is between 27 and 29 °C, hazardous mine gases, employee neglect of personal protective equipment, and a lack of hazard awareness in some workplaces. Based on these issues, the study's objectives are to illustrate how corporate OSH is used, provide data on work accidents and potential risk factors in the workplace, and make recommendations for a number of work practice guidelines. The world's most hazardous occupation is mining. the Ministry of Energy and Mineral Resources' statistical data. In mining, accidents frequently happen. Hazardous field conditions, unsafe work practices, and a disregard for safety are the root causes of dangerous working circumstances. As a result, fatal work accidents frequently happen. In order for businesses and employees to reduce the risk of work accidents, this research's goal is to identify the factors that lead to accidents at work in the coal mining industry. Data sources for this study were gathered from "Google Scholar" using the keywords "The year of publication is limited to 2018–2022." This study used the systematic literature review (SLR) technique. Risk variables are the most crucial elements employed in preventing work accidents, according to a study of the literature on how age, job experience, the workplace, and body parts affect employee work accidents., and the role of the company in influencing the occurrence of accidents. work accident.
