Developing a wood lathe machine with speed control and workers' anthropometry to increase the productivity of broom industry
Get PDFTo overcome the economic crisis in the current situation, the community in the village of Dawan Klungkung-Bali was encouraging small and medium-sized businesses, including the home industry sector, specifically the production of broom handles that made from leftover wood. The production process is quite simple where the worker utilized wooden chisels and hand grinders to create the broom handle. Even though the methods and tools are simple, it takes a long time to complete one broom handle. In addition, the process continued with the sanding process to smoothen the product, which caused the workers to quickly become fatigued due to the long duration of the bending down and pressing gestures. To address this issue, a wood lathe with speed control and height adjustment based on worker anthropometry was developed. This study was volunteered by ten workers that compared the workload of both traditional and proposed method. Workload is determined by measuring the worker's pulse with a pulse meter, skeletal muscle complaints that observed using the Nordic Body Map questionnaire, and worker productivity that calculated by dividing the number of broom handles produced per hour by the workload

Blended learning as a choice of learning model in vocational education after the COVID-19 pandemic
Get PDFVarious online learning models were applied during the COVID-19 pandemic, ranging from simply using communication applications, to those using learning systems or a combination of both. The majority think that online learning must be done face-to-face, even though online. In each meeting, it is usually equipped with material sharing, exercises or even video tutorials. Students have extensive opportunities to communicate with lecturers, either during scheduled meetings or outside of schedules. Although the learning process will be returned to normal due to the end of the pandemic, the online learning experience for two years has given a distinct impression to students and lecturers. There is a desire to maintain it as a distraction from classroom learning. Blended learning, namely the learning process in the classroom interspersed with online learning is the right choice. The study program and lecturers must jointly make an agreement to determine the material and portion size between offline and online learning, as well as monitor and evaluate its implementation. The quality of the output must be able to be maintained or even improved through this blended learning process
Analysis of non domestic water needs in the clean water supply in Badung Regency
Get PDFThe need for clean water is generally divided into two groups, namely domestic water needs and non-domestic water needs. Non-domestic water needs are water needs other than for household purposes such as for education, industry, tourism, social and others. In general, the determination of non-domestic water demand is estimated to be around 20-25% of the total domestic water demand. Badung Regency has characteristics as the main tourist area in Bali as evidenced by the existence of 33 tourist destinations, both cultural tourism, natural tourism, artificial tourism and youth tourism. With these characteristics, this study emphasizes the analysis of non-domestic water needs in the tourism sector. The research was conducted by analyzing various factors related to the need for clean water in the tourism sector such as hotel accommodation, tourism support facilities and the number of tourism objects available. The results of this analysis are compared with domestic water needs according to the existing population. The analysis shows that non-domestic water demand for tourism accommodation (hotels, villas and condominium hotels) is 186.76 liters / second, for tourism objects is 7.64 liters / second, restaurants and bars is 24.21 liters / second.

Quick and concise land boundary mapping using a drone at Villa Buccu, Kerobokan, Badung, Bali
Get PDFThe effective measurement and mapping of the land is retrieval of accurate data according to position, in accordance with mapping provisions and efficient in both cost and time. One way that data can be retrieved effectively and efficiently is by using a drone, commonly called an unmanned aerial vehicle (UAV).Drone is a vehicle equipped with a wave control system, precision navigation (Global Positioning System/GPS) and flight control electronics so that it is able to fly according to flight planning (autopilot). This drone makes it possible to track the position and orientation of sensors implemented in local or global coordinate systems. With the drone itself, it saves time because it can have an image of an area. Premark / Ground Control Point (GCP) is a point that is commonly used to improve measurement accuracy in mapping using drones, in this case using the Global Positioning System (GPS) Geodetic / RTK Hi Target tool. Mapping Using Drones was then used by many people, including for the purposes of villa spatial planning, so to support this activity a land boundary mapping was carried out at Villa Buccu, Kerobokan, Badung Bali.
