Abstract

Erratic weather, such as intense heat followed by heavy rain, is causing air pollution in the sky of Jakarta. According to the SNI 03-6389-2011, which deals with energy conservation in building envelopes, the overall thermal transfer value (OTTV) for walls should not exceed 35 W/m2. This study aims to analyze OTTV in Class T and Class S. Class S uses clear glass, while Class T has a shading device in the form of a sunglass sticker. The method used involves calculating the total outer wall area, glass area, window-to-wall ratio (WWR), solar factor value, and then obtaining the OTTV. The results of the study show that the WWR value for Class T was 0.5, while for Class S it was 0.4. The OTTV value in Class T is 58.74 W/m2, whereas the OTTV in Class S is 70.64 W/m2. Despite both classrooms not meeting the SNI requirements, the classrooms using shading devices have OTTV values closer to the SNI standard.

Abstract

The pandemic era that occurred in 2020 is a new history in human civilization. The emergence of the pandemic has limited interaction between humans and the surrounding environment. Limited interaction during the pandemic is manifested in the social distancing program, indirectly this program can reduce the sense of social concern, kinship and togetherness between residents. Not only does it have an impact on social welfare, this program will also limit buying and selling activities in markets and local village environments. Thus affecting the level of economic welfare of local communities. The pandemic era that has ended has not been able to restore the economy and health of the affected communities, so various individual and group efforts still need to be made that can increase people's income. Some of the problems above are the background and reasons for choosing Simomulyo Village as our KKN object. Simomulyo village has a very strategic location because it is located in the city center and has a fairly large market. Of course, this condition causes Simomulyo village to receive a significant impact from the pandemic period to the post-pandemic period. To solve existing problems, we and the Simomulyo Village community will work together to maximize the benefits of implementing the waste bank program. The success of this optimization is marked by increased awareness and insight of the village community regarding waste that is ready to be recycled and sold to increase village income. The hope is that, apart from being useful in creating a healthy environment, the waste bank program will also be useful in improving economic and social welfare for the people of Simomulyo Village. This is realized in the form of a waste bank account which is accumulated into cash to ensure the smooth implementation of several village activities.

Abstract

Disaster is a very sad condition for the victims of the disaster, which destroys, eliminates, and destroys all aspects of people's lives, even the lives of relatives affected by the disaster. The destruction of infrastructure, buildings, and houses experienced by the victims caused them to have no shelter and shelter for themselves and their relatives. The absence of shelter for them after the disaster will cause very worrying problems and will have a continued impact on their next life. Housing as a temporary shelter for them is a very urgent need and it is very important to be held quickly to meet the needs of their next life. The provision of fast housing for victims affected by disasters is the focus of this research. The method of providing fast homes with a modular system is a building method where building components are built based on module units. These modules are assembled and assembled for easy use and disassembly. This type of house is increasingly being adopted in many areas, especially in areas where there are many disasters, because of its speed and efficiency. In this study, the aesthetic aspects and the flexibility of the container are excluded, but the emphasis is on the availability of basic residential space and the arrangement of the basic space module. Therefore, various efforts have been made to meet user demands for different living spaces by using only a few module units using a one-room system consisting of a living room, kitchen, bathroom, and sleeping area sufficient to meet basic living needs. daily. The function of the building is divided into three zones: service, public, and private.

Abstract

Wireless Sensor Networks (WSN) are wireless networks with many sensor nodes covering a relatively large area. One of the weaknesses of WSN is the use of relatively high energy consumption, which affects the quality of network services. Although the WSN network routing using the DV-Hop algorithm is widely used because of its simplicity, improvements need to be made to improve energy efficiency so that the network lifetime is more optimal. This article proposes an enhanced DV-Hop algorithm compared to other algorithms to improve network energy efficiency and quality of service. There are three approaches to improving the DV-Hop algorithm. First, the selection of the CH node is based on the distance to the Base Station so that the selected CH node does not have a long distance from the base station. Second, the selection of CH nodes must have a number of neighbouring nodes above the average of other sensor nodes. Finally, each selected CH node calculates the minimum distance to the previously selected CH node to ensure that the selected CH nodes are not adjacent to each other. The proposed approach obtains better total data packets sent to the base station, energy efficiency, and network age using Matlab simulation software by comparing the enhanced DV-Hop algorithm with the original DV-Hop algorithm and three other routing algorithms.

Abstract

PT XYZ is one of the manufacturing industries engaged in the production of palm oil processing. The products produced are cooking oil and margarine. So far, the implementation of activities has been hampered by the current layout conditions having a less efficient material handling path length, in addition, the distance between facilities is too far ± 150m which results in repeated transportation, this results in PT XYZ's material transfer activities being less effective. Therefore, this study aims to redesign the layout of production facilities in order to minimize material handling costs and raw material movement distances to be more effective. From these problems, the method used is the CRAFT (Computerized Relative Allocation of Facilities Techniques) method, this method can be done with the help of FTC (From to Chart), ARC (Activity Relation Chart) and ARD (Activity Relationship Diagram) calculations. The results of this study showed that the CRAFT algorithm succeeded in saving total material handling costs of Rp. 469,352.04 per day and reducing the total distance of movement by 67.15 meters. The reduction in material handling costs achieved was Rp 2,114,734.77 or around 81.84%, while the reduction in material handling distance reached 306.85 meters or around 82.05%.

Abstract

In an era of increasingly fierce industrial competition, service optimisation and operational efficiency are the main keys for companies to maintain competitiveness. This study aims to analyse and forecast the demand for calibration services at PT XYZ using the Autoregressive Integrated Moving Average (ARIMA) method. Calibration demand is an important indicator in managing company resources, so accurate forecasts can help PT XYZ improve operational efficiency and service quality. The data used in this study is secondary data that includes calibration demand data. The analysis process is carried out through several stages, including model identification, parameter estimation and diagnostic testing to ensure that the resulting model optimally reflects the historical data patterns. The ARIMA (1,1,1) model was identified as the best model with a low forecasting error rate, namely the Mean Absolute Percentage Error (MAPE) of 2.04%. The forecasting results show a predicted calibration demand of 9 requests per month for the period November 2024 to April 2025. These results provide strategic insights for PT XYZ to manage resources more effectively, such as scheduling staff, managing equipment capacity, and reducing customer wait times. This study also confirms that the ARIMA method has a good ability to capture seasonal patterns and trends, thus providing accurate forecasts for strategic planning.
