The negative impact is given as hazardous and toxic waste (HTW) which will have negative consequences if not properly managed. Evaluating of the management of HTW is an important thing to do to ensure that the management is in compliance with regulations. The objective of this study is to identify and quantify the types and amounts of HTW in the X Bandung City industry. This company is committed to electronics with a domestic market share. Descriptive observation research with objects in the form of activities of the production process, source, reduction process, packaging, storage, labelling and transport of HTW. The data collection period occurred between July 2019 until June 2020. Based on the results of the study, it was found that the IPA (isophthalic acid liquid) used was the most HTW followed by contaminated materials such as broken cells/modules, used coolants, worn personal protective equipment, rags and parts of PCB. The total HTW produced is 1,176 tons/year, while the amount of IPA used (isophthalic acid liquid) is 0.414 tons /year.

This turbine configuration though unpopular for large-scale generation has found a niche market in the way of offshore energy harvesting. However, offshore wind has its challenges. In this thesis a detailed comprehensive study of a proposed V-shaped vertical axis turbine rotor is performed in order to examine its structural and aerodynamic characteristics. The design met and exceeded the safety parameters establish for test bed operation, showing a factor of safety of 1.87 with regard to fatigue stress response. A satisfactory fatigue stress design life was also achieved. Both experimental and numerical aerodynamic data have relatively good agreement achieving an overall maximum power coefficient of 0.2589 numerically and 0.251 experimentally.
