Abstract

Developers construct low-cost housing specifically for the low-income demographic. While the number of people interested in this sort of home is growing in Indonesia, in practice, there is sometimes a delay in the development process due to waste. The goal of this research is to identify and describe the waste that occurs during the construction of low-cost dwellings. Field observations and interviews with 17 contractors working on four low-cost housing projects were used to gather data. The findings of the analysis demonstrate that various wastes arise throughout the construction process' flow, including waste Overproduction, Inventory, Defect, Motion, Transportation, Processing, and Waiting in each job, all of which stymie the development process. This study was not conducted at the level of the developer or material supplier, but rather at the project site, specifically on every job in the process of constructing a consumer's home. This study uses seven forms of waste that exist in a succession of manufacturing processes, namely Overproduction, Inventory, Defect, Motion, Transportation, Processing, and Waiting, which are rarely employed in construction projects.

Abstract

Technology nowadays is always changing very fast. Automated tools are used to face the advanced technology in the warehouse industry, such as automated guided vehicles (AGV). It becomes a common daily vehicle when working in the warehouse, especially on the shop floor. It means collaboration between AGVs is needed and has become important. This paper suggests how to avoid collisions between AGVs and how to avoid obstacles is a practical problem if two or more AGVs interact with each other. This is a common need that should be addressed. As a result, a more effective system design should be created and implemented. This paper used a three-tier internet of things (IoT) structure to avoid collisions and reduce path deviation to design an AGV collaboration system. The IoT was used to authorize AGVs to communicate with each other by transmitting position messages. In this situation, AGV would be aware of other AGV positions and would decide what to do next. According to the findings, two AGVs can avoid colliding by knowing each other's positions in any path scenario by recognizing obstacles through Light Detection and Ranging (LIDAR) detection. This paper designed an AGV collaboration system using the Robot Operating System (ROS) and conducted an experiment to test its practicality. The experiment simulated a warehouse intersection in the real world. This study used the statistical ANOVA method to identify motion planning parameters concerning final AGV position error values.

Abstract

Despite the continued outbreak of the new COVID-19, few studies on the stress associated with the pandemic have been done. In this study, attributes of mental health perceived by hotel employees and hotel customers were examined, and the service quality, in terms of reliability, responsiveness, assurance, empathy, and tangibles. We found and verified attributes based on qualitative approaches. As a result, it was found that the relationships between the proposed variables had no significant effects. This study provides an evaluation of the impact of mental health on hotel employees' performance and the level of service they deliver.

Abstract

Climate crisis is arguably the biggest challenge that the world is currently facing. Extreme weather events are becoming more frequent while the continuous rise in sea level is putting billions of lives will be at risk. Solving the climate crisis requires global carbon emission to peak by 2025, which means that carbon-intensive fossil fuels must be replaced by low-carbon renewable sources in fulfilling our energy needs. Solar energy, due to its abundance, rapidly decreasing cost, and low carbon emission, is one of the most promising energy sources. Many studies have calculated and compared the life cycle greenhouse gas (GHG) emissions of solar photovoltaic (PV) systems with conventional fuel generation. Nevertheless, the life cycle GHG emission values are affected by many location- and technology-dependent factors. This work provides an up-to-date and realistic assessment of the life cycle GHG emission for PV systems in Indonesia through thorough literature review and harmonization according to Indonesian parameters. The study shows that PV GHG emission of 37.3-64.3 gCO2eq/kWh are much lower than the current emission intensity of the Indonesian power sector. By fulfilling rising electricity demand using PV, up to 654 MtCO2eq can be avoided annually by 2050.

Abstract

Supply chain flow is a major concern for food security, particularly to ensure that food is not lost between farmers and consumers. Food security has become a highly emotive issue, as chronic hunger, local food shortages, and sudden increases in food prices are strongly influencing public sentiment and reaction. This raises concern for the assessment of supply chain management and sustainable food security in Nigeria, using honesty among supply chain participants, effective storage facilities, and quality of seed as a determinant for sustainable food security. A survey research design was adopted for this study, using a structured questionnaire. Convenient and Purposive sampling techniques were used to select 80 farmers from the North-Western state of Nigeria. Descriptive statistics were used to analyse the data collected, which was presented using charts. The findings of this study show that honesty among supply chain participants, effective storage facilities for farm produce, and the quality of seeds to plant will enhance nutritional foods in society, promotes both affordability and high profits for all participants in the supply chain based on the response of the selected farmers. It was further revealed from the study that Government intervention in terms of subsidy and credit facilities to the farmers are not well harnessed by the real farmers that are actually in the business of farming. Therefore, it was recommended, among others, that there should be an effective feedback mechanism from the government to ensure the subsidy is actually addressing the purpose of its establishment.
