This study aims to evaluate the feasibility of establishing a gamma irradiator pilot project in Indonesia to reduce food loss and food waste, as well as to enhance the value of export commodities. Gamma irradiators have the potential to extend shelf life, improve food safety, and reduce losses during distribution and storage. The research methodology involves weighting to assess the feasibility of location selection, incorporating secondary data analysis and economic value-added analysis. The results indicate that the PUSPIPTEK Serpong location meets all mandatory criteria and nearly all non-mandatory criteria, making it a suitable site for this pilot project. The operation of the gamma irradiator in Serpong has successfully increased the volume of irradiation services, though its utilization is predominantly for export purposes. The main challenges include a negative public perception of irradiated food and a lack of education on its benefits. This study concludes that gamma irradiators are effective in reducing food loss and food waste, as well as increasing the value-added of export commodities. Strong government support and continuous education programs are necessary to improve public acceptance. Future research could focus on long-term evaluations of the impact of gamma irradiators and the development of more effective educational programs.

In recent years, building collapse accidents have occurred from time to time in China, causing serious casualties and property losses. In order to monitor the abnormal phenomena of buildings in time, Intelligent Building Safety Monitoring System based on computer vision is proposed. Using ZigBee wireless sensor network, the crack images and sensor monitoring data of monitoring points are obtained and transmitted to the local control computer. After the data are processed by the integrated crack image recognition and measurement algorithm based on OpenCV, they are displayed on the terminal monitoring software. If the data is abnormal, the early warning function is triggered, and the intelligent monitoring and danger early warning functions for building safety are realized.

Indonesia has a new capital, officially known as Nusantara (IKN). The nearest access to and from IKN is through Balikpapan Bay, a confined waterway that may eventually result in traffic congestion and interfere with shipping operations. This research aims to investigate ship traffic and safety governance policies, as few researchers have previously studied this issue in the IKN waters. We collected the empirical data in four steps. Firstly, we conducted in-depth interviews and focus group discussions attended by related stakeholders, such as the Harbormaster and Port Authority, the Indonesian Maritime Court, the Navigation District Officers, SOE Port Managers, Local Government, and Shipping Companies Association. Next, we distributed questionnaires to shipping operators. Furthermore, using triangulation techniques, this research suggests the need to harmonize regulations implemented by related agencies involved in shipping activities. The last step was determining ship routes to ensure maritime safety and ship traffic efficiency. The proposed harmonization would provide port and shipping operators with business certainty in accordance with applicable laws. The research also recommended sharing authority between the IKN Authority Agency, which is responsible for the exploitation of water areas, and the Transportation Ministry, which regulates maritime traffic and safety.
