Increasing traffic activity at unsignalized intersections often results in congestion and delays. The intersection of Jl. Imam Bonjol and Jl. Daya Nasional experiences these conditions, making performance evaluation necessary. This research tends to scrutinize the intersection performance under existing conditions and five-year projected conditions and to identify appropriate improvement measures. The analysis was carried out using the 2023 Indonesian Road Capacity Guidelines (PKJI 2023) and PTV VISSIM microsimulation software. Data on intersection geometry, vehicle speed, and traffic volume were collected through CCTV observations on weekdays and weekends. The results show that under existing conditions, the degree of saturation reached 1.170 with an average delay of 33.75 seconds (LOS D). In the five-year projection, the degree of saturation increased to 1.239 with an average delay of 53.69 seconds (LOS E). These findings indicate a decline in intersection performance, highlighting the need for alternative traffic management measures to improve operational performance and service levels.

This study aims to identify the factors causing delays in the issuance of the Certificate of Pratique (COP) for foreign vessels and to review the standard procedures applicable at the Banten Health Quarantine through the role of PT. Bahari Tirta Jaya Banten Branch. The COP is a critical document certifying that a vessel has met health requirements and is permitted to have contact with the shore (berthing/stevedoring). The research method employed is field research through direct observation at the port and library research involving laws, regulations, and relevant port literature. The research findings indicate that delays in COP issuance are caused by several primary factors, including: (1) incomplete ship administrative documents, (2) quarantine procedures requiring additional inspections, (3) poor ship hygiene conditions, (4) limited human resources within the quarantine office, and (5) technical constraints in the quarantine information system. These delays have a significant impact on ship berthing schedules, the efficiency of loading and unloading processes, and potential financial losses for shipping companies. This study recommends the need for improved coordination between ship agents and Health Quarantine authorities, evaluation of procedural efficiency, and strengthening of information system resources to ensure smooth services within the Banten Port area.

This research aims to deeply analyze the process mechanism for the management and issuance of the National Pollution Prevention Certificate (SNPP) by PT. Multi Jaya Samudera Belawan at the Port Authority and Harbormaster’s Office (KSOP) Belawan. The SNPP is a crucial document that certifies a vessel’s compliance with technical and administrative requirements regulated by national laws and international conventions, specifically concerning the prevention of marine environmental pollution. The research methodology employed is a qualitative descriptive case study, focusing on direct observation of the procedural stages and interviews with relevant parties within the shipping agency and the KSOP institution. Data were collected through field observation during the fieldwork period and literature study relevant to ship certification procedures. The findings indicate that the SNPP issuance process involves a series of structured stages, beginning with the application submission, verification of supporting document completeness, followed by a physical vessel inspection by KSOP inspection officers to ensure that all pollution prevention installations and systems function according to the required standards. The final stage involves issuing the certificate once all requirements are met. Despite the established procedures, this study identified several key challenges, including: (1) Administrative Delays, which can interfere with the processing schedule; (2) Lack of Understanding among business actors regarding the latest detailed procedures, often resulting in incomplete documentation; and (3) Limited Technical Support, encompassing digital information systems or other supporting facilities. The optimization of SNPP issuance heavily relies on solid coordination between the shipping agency, ship’s crew, and the regulator (KSOP). The implications of these findings highlight the importance of regular dissemination and socialization of the latest regulations and procedures, as well as enhancing the efficiency of digital administration systems to minimize waiting times and ensure vessel compliance with marine pollution prevention standards.

Internal control is a crucial aspect for SMEs in maintaining the reliability of revenue recording and preventing the risk of misappropriation. This study aims to analyze the implementation of internal control in the revenue cycle at Exmo Tea Café and to evaluate its effectiveness through internal audit. The research uses a qualitative descriptive approach with data collection through interviews with management personnel directly involved in transactions and financial recording. The analysis is conducted using the COSO framework, which includes five main components: control environment, risk assessment, control activities, information and communication, and monitoring. The research results indicate that Exmo Tea Café has implemented several basic elements of internal control, such as recording transactions through a cashier application, daily cash reconciliation, and reporting to the owner. However, the effectiveness of these controls is still limited because the segregation of duties between receiving and recording is not optimal, risk assessment is reactive, documentation and report archiving are not systematic, and monitoring is conducted informally. In addition, there are no formal policies regarding operational standards (SOPs) or internal audit procedures that could serve as guidelines for continuous control implementation. These conditions have the potential to lead to risks of fraud, recording errors, and delays in financial reporting. Therefore, these findings underscore the need for a comprehensive enhancement of the internal control system, including strengthening the separation of duties, conducting preventive risk assessments, providing employee training related to financial governance, as well as implementing more formal monitoring and documentation. These improvements are expected to increase reporting accuracy, operational effectiveness, and minimize the potential for errors or fraud in the company's financial activities.  

This community service activity aims to improve the efficiency of inventory management at Zencha MSMEs through the design and implementation of a Standard Operating Procedure (SOP) and a spreadsheet-based inventory recording system. Prior to this program, Zencha MSMEs managed its inventory manually without written procedures, which often caused stock discrepancies, delays in restocking, and difficulties in monitoring raw material availability. The methods used in this activity included observation, interviews, SOP design, system socialization, and direct implementation assistance. The SOP was structured to regulate the process of receiving, recording, storing, and using raw materials, while the spreadsheet template functioned as a digital tool to record stock movements automatically. The results show that after the implementation, inventory management became more organized, transparent, and measurable. The business owner was able to monitor stock levels more accurately, determine restocking time more effectively, and reduce the risk of stock shortages. In addition, employees demonstrated better discipline in recording inventory according to established procedures. This program proves that the implementation of SOP and digital-based inventory recording can significantly improve operational efficiency and support the sustainability of micro and small enterprises.
