Submarine pipelines are vital infrastructures in aviation fuel distribution, carrying high risks of operational disruption, safety issues, and environmental pollution. In 2025, the aviation fuel receiving submarine pipeline at Integrated Terminal Ampenan was deformed due to mechanical pulling by MT Anargya I, causing system shutdown. This incident created risks of seawater intrusion, marine pollution, and potential fuel shortages at Lombok International Airport. This study evaluates the effectiveness of applying a double-ended draining method combined with an oil bubble trap as a fast, safe, and sustainable solution for submarine pipeline repair. Using a case study and descriptive-analytical approach based on the Continuous Improvement Program (CIP), the research analyzed quality, cost, delivery, safety, environmental, and workforce aspects. The results showed the method effectively drained aviation fuel without seawater contamination, prevented marine spills, maintained fuel quality within specifications, and completed repairs before critical stock levels were reached. Additionally, it provided significant cost savings compared to emergency supply operations and achieved zero safety incidents and environmental pollution. The integration of double-ended draining and oil bubble trap proved to be an effective, adaptive innovation with strong potential for replication and standardization in other aviation fuel submarine pipeline systems.

This article explores the concept and implementation of restorative justice in Indonesia, an approach currently at a crucial crossroads within the criminal justice system. Rather than solely focusing on punishment, restorative justice offers a path towards repairing relationships between victims, offenders, and the community, seeking solutions oriented around conflict resolution. Through comprehensive analysis, this paper identifies the philosophical foundations and regulations supporting the adoption of restorative justice, while dissecting the dynamics of its application across various levels of legal processes in Indonesia. However, this noble endeavor is not without its challenges, ranging from institutional resistance and uneven understanding to harmonization with the conventional criminal law framework. Behind every case lies a human story yearning for more substantive justice. Therefore, this article argues that the success of restorative justice does not merely lie in its legal umbrella, but in our ability to understand and embrace the human dimension in every dispute resolution process. Consequently, this paper recommends adaptive and collaborative strategies to strengthen the role of restorative justice, ensuring it can guide our criminal justice system towards a more just and dignified future for all parties.

Project scheduling is an important element for shipyard companies to gain more profit. The most frequently used analysis is the Critical Path Method (CPM). However, in reality, planning using the CPM method is considered less efficient because it does not consider the productivity of each job in it and adds safety time which causes the project duration to become longer. In accordance with the above problems, a new method for planning project schedules is now being developed, namely Critical Chain Project Management (CCPM). CCPM is a project planning method that emphasizes the resources needed to carry out existing tasks in the project. This method is carried out by eliminating multitasking, student syndrome, Parkinson's law and providing a buffer at the end of the project. In this final project, a comparison of the duration of the results of applying the CCPM method with the Critical Path Method (CPM) method is carried out in a case study of ship repairs at PT. Galangan Kapal Madura. The initial project scheduling uses the traditional method in the form of a Gantt chart which is then broken down in more detail and completely with the relationship between activities in the form of CPM, and then will be compared with the duration of the results of CCPM scheduling which has eliminated multitasking, eliminated Safety time for each activity and provided a buffer in the work.

Osteoarthritis is a progressive degenerative joint disease characterized by cartilage damage, chronic inflammation, and functional limitation. Current treatments mainly focus on symptom relief and mechanical correction, with limited ability to restore the biological environment of the joint. Recently, mesenchymal stem cell derived secretome has emerged as a promising cell free regenerative therapy with anti-inflammatory and tissue-repair potential. This study aimed to systematically review the role of mesenchymal stem cell secretome in osteoarthritis management, both as an intra-articular therapy and as an adjuvant following surgical intervention. A literature review was conducted on relevant preclinical and early clinical studies published over the past decade. The selected articles were analyzed to evaluate therapeutic mechanisms and clinical implications. The findings indicate that intra articular administration of secretome reduces inflammatory mediators, suppresses catabolic enzyme activity, and improves cartilage integrity in various osteoarthritis models. Early clinical evidence also suggests improvements in pain and joint function, especially in patients with mild to moderate disease. Furthermore, secretome shows potential as an adjuvant therapy after surgery by supporting biological recovery of joint tissues. Overall, mesenchymal stem cell secretome represents a promising component of a multimodal strategy for osteoarthritis management, although further clinical trials are required to confirm its efficacy and safety.

Aortic dissection is a cardiovascular emergency characterized by a tear in the aortic intima layer and the formation of a false lumen, posing risks of fatal complications such as rupture and organ malperfusion. Stanford type B dissections may be managed conservatively; however, complicated cases require intervention. Thoracic Endovascular Aortic Repair (TEVAR) has emerged as the preferred modality, offering lower perioperative morbidity and mortality compared to open surgery. To report the first TEVAR procedure performed in Manado on a patient with Stanford type B aortic dissection, highlighting the technical approach, operative challenges, and clinical outcomes. A 62-year-old male with a history of hypertension and chronic chest pain was referred following a CT angiography that revealed a Stanford type B aortic dissection with an entry site in the proximal descending aorta. TEVAR was performed with stent-graft placement in zone 2 and a chimney graft to preserve perfusion of the left subclavian artery (LSA). Intraoperative aortography confirmed false lumen exclusion without endoleak. The patient showed significant clinical improvement and recovered without postoperative complications. The procedure was technically and clinically successful, with no major complications. Postoperative evaluation confirmed stable stent position and maintained LSA perfusion. This case demonstrates that TEVAR can be safely implemented in non-tertiary regional hospitals with thorough preparation. The first TEVAR procedure in Manado illustrates that this technique can be an effective solution for complicated type B aortic dissections. This experience marks a milestone in the development of endovascular services in resource-limited settings and may serve as a reference for similar institutions in Indonesia.
