Abstract

The increasing demand for coal energy globally has led to the rapid growth of the coal industry in Indonesia. It is projected that coal energy will still dominate in the world until 2050. This development will undoubtedly impact the quality of the environment, one of which is related to air pollution. As one of the distribution chain links, coal port facilities require attention regarding air quality management. This research shows that the source of fugitive pollutants from coal loading and unloading activities at the research location comes from supporting equipment for loading and unloading activities and coal stockpiles. These tools continuously emit non-chimney contaminants, namely coal dust. Non-fugitive pollution is generated by heavy equipment and generators used in activities in the workshop area. Measurement of ambient air quality at the study site indicated that the particulate parameters (TSP, PM10, and Dustfall) needed to be comparable with the standards. In contrast, the gas parameter that was the most significant was the SO2 pollutant. Efforts to control air pollution are using sprinklers and installing windproof nets, which are indicated to be quite effective in reducing dust in the crusher area. Recommendations in controlling air pollution are to automate the sprinkler system for watering and monitoring airflow and plant trees with the ability to absorb SO2 effectively.

Abstract

Trolley is a means of transportation that is often used in warehouses to move goods from one place to another. Driven trains are widely used because they are economical and do not require too much maintenance. However, in its use there are still obstacles such as piles that are too high so that goods fall, there is no control over the stroller so it cannot stop suddenly. The redesign of the trolley requires information related to customer needs, so this study aims to identification customer needs for the trolley using the Quality Function Deployment (QFD) method. The customer needs obtained include a trolley that is safe to use, a comfortable trolley, a trolley that is easy to fold, a trolley that is easy to carry, and a strong trolley material. The dominant technical characteristic based on QFD results is the type of material and the thickness of the trolley material is 135.00. The specifications of the trolley are 70 x 50 x 67 cm, plate iron material type, hollow iron frame material type, iron pipe handle material type, rubber wheel material type, have handbrake, and fastening rubber rope.

Abstract

Several studies that have been carried out can identify signs of an impending earthquake. One example of changes in the concentration of Rn (Radon) in the area affected by an earthquake. The purpose of this study is to design and create a prototype of an earthquake early detection system through real-time measurement of radon gas concentrations in the air where the measurement data results can be uploaded to the internet network and viewed by users in real time through a site. To detect it, a scintillation detector is used, in the design of the detector system the ZnS(Ag) scintillation type will be used. Data analysis was carried out in several ways, stability analysis of the count by measuring n times at the same concentration of radon gas and counting time, counting efficiency, calibration of counting and detection of limits. The data monitoring system is carried out through the website in real-time. Data is sent using an internet provider with sim900 every minute to 58 every hour. From the tests carried out on tap water continuously in the BATAN market area for 24 hours, it can be seen on the site that the average concentration value of Radon compounds in tap water at that location is 59.91 Bq/M3 where the total concentration is still below the threshold value. set by the ICRP (International Commission on Radiological Protection) is around 200 Bq/M3.

Abstract

In 2020, PT Austindo Nusantara Jaya Agri started to run an independent farming program called the “Tani Mandiri” program which aims to empower the community in Tobing Jae Village. This program targets the Sinar Jaya Farmer Group I and was replicated for the Sinar Jaya Farmer Group II in 2021. Through this program, PT Austindo Nusantara Jaya Agri provides budget assistance for the provision of integrated pest control managed by farmer groups. The social return on investment (SROI) method is used to measure the magnitude of the impact of the program. From the analysis that has been done, it is known that this program has a fairly high SROI value of 1.94. In addition, it is also known that the payback period of the Tani Mandiri program has an average of 0.66 year. This shows that the investment from this program is still less than one year. These two results indicate that the empowerment program carried out is classified as a sustainable program in Tobing Jae Village to improve the welfare of the local community and also farmer groups who participate in the Tani Mandiri program

Abstract

The floating rice field program for food security with the “jajar legowo” planting system, which is also abbreviated as Sapu Tangan Jarwo, is part of PT Sahabat Mewah dan Makmur's social responsibility program for the community around the company's environment. This program utilizes flooded agricultural land with floating rice field technology with a row planting system. This program was implemented from 2020-2021 with the target of farmer groups in the Jangkang and Balok Villages, Belitung Timur Province. The impact of the Sapu Tangan Jarwo program was analyzed using the Social Return on Investment (SROI) method. In addition, the payback period (PP) is also analyzed to determine the time required to return the investment value that the company has given. From the calculations that have been made, the Sapu Tangan Jarwo Program has an SROI and PP value of 2.47 and 1 year 3 months 1 day, respectively. Based on the calculation results, it can be seen that the Sapu Tangan Jarwo program can be continued because it can provide benefits and outcomes for the surrounding community.
