Abstract

East Kalimantan Province is a region in Indonesia where the mining and quarrying industry is still the main sector that influences the regional economy and Indonesia as a whole. However, local governments hast to make efforts to encourage other economic sectors to avoid a decline in economic growth which is influenced by fluctuations in world market prices. For example, the agricultural sector, including fisheries, is the most important potential commodity in East Kalimantan. The development of fishing ports in the coastal areas of East Kalimantan is very important as a center for local economic activities and also as a place to maintain the sustainability of fish resources. Apart from that, with the progress of the development of the New Capital City of Indonesia (IKN) in the Balikpapan and North Penajam Paser areas, it is important to review the function of the port as supporting water transportation connectivity in the IKN.

Abstract

Energy is a fundamental element in economic and social development, with oil and natural gas remaining the primary energy sources in Indonesia. To support the distribution of hydrocarbons from production facilities to onshore locations, subsea pipelines serve as vital infrastructure in the upstream oil and gas industry. However, subsea pipelines face various external risks, including dropped ship anchors, which can cause significant damage both technically and environmentally. This study aims to analyze the risk level of dropped anchors on subsea pipelines in Natuna. The methodology involves data collection related to pipeline characteristics, vessel traffic, and anchor types. Consequence analysis is conducted by calculating pipeline dent levels due to anchor kinetic energy based on the DNV-RP-F107 guideline. The results show that the anchor impact energy on the pipeline is approximately 3,94 kJ, placing the pipeline consequence level in the <5% dent/diameter category. Risk assessment using a risk matrix indicates that the risk level remains within the ALARP (As Low As Reasonably Practicable) threshold, meaning the risk is acceptable with reasonable mitigation measures. The findings suggest that although dropped anchors can cause pipeline deformation, the resulting damage remains within safe limits. However, to further reduce potential risks, additional mitigation measures are required, such as vessel traffic monitoring, designated anchor-free zones, and enhancing pipeline resilience against external impacts.

Abstract

Coastline's change was caused by the movement of sediments influenced by waves, wind, and materials around the shore. The movement of sediments around the coast resulted coastal dynamics marked by abrasion and Erosion. In the Balikpapan region, especially on the East Balikpapan Coast near the Makassar Strait, causing high waves on the beaches in this area, one of the areas that was once affected was Manggar Baru Beach, where there was a settlement less than 10 meters from the shoreline. With the changes in the coastline, it could lead to floods, changes in the area, damage to facilities around the coast, and so on. This study is modeled with the help of an application to understand the characteristics of the coastline to get trends in the present and projected future changes for disaster mitigation. It was also found that the average changes in 2024 were 0.829 m/year, in 2027 were 1.984 m/year, in 2032 were 3.982 m/year, and in 2042 were 7.689 m/year. Changes that occurred in Manggar Baru Beach were predominantly experiencing Erosion every year.

Abstract

The process of loading and unloading ships is a critical activity in the logistics chain that impacts the efficiency and operational costs of ports. This study aims to evaluate the use of Network Planning methods in planning and controlling the time of the ship loading and unloading process. The research was conducted using historical data on the loading and unloading times of ships, as well as related activity schedules at Semayang Port, Balikpapan. This study adopts an approach by analyzing the application of network planning on the unloading process of the MV Future Ocean 14,514 DWT ship in the form of an S-Curve, then analyzing alternative critical paths along with duration acceleration using the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) on days (conditions) with better work weight consistency. Additionally, it analyzes how this affects manpower and manhour efficiency. The results of this study indicate that the application of the CPM and PERT methods led to a reduction in job duration from 1.408 minutes to 1.227 minutes using CPM, and 1.224,67 minutes using PERT. Based on the duration acceleration, the need for additional manpower increased from 21 to 24, resulting in a -14% decrease in manpower efficiency. The total manhour value changed from 3.941,28 MH to 3.936 MH with a 0,13% increase in manhour efficiency for CPM, and 3.916,8 MH with a 0,62% increase in manhour efficiency for PERT.

Abstract

The maintenance process involves the use of various equipment, machinery, and workspaces, all of which inherently present occupational hazards. If these risks are not adequately addressed, they may lead to workplace accidents. Ensuring worker protection remains a critical concern due to the persistent occurrence of occupational incidents and the presence of workplace hazards that pose significant risks to employees. Therefore, this study aims to identify and assess occupational accident risks during unit maintenance, develop strategies to mitigate these risks, and enhance occupational safety and health (OSH) practices at company. This study identified 27 potential workplace accidents arising from six major hazard categories. These hazards were incorporated into a structured questionnaire, which was then distributed to relevant workers to gather empirical data. The collected responses were analyzed and systematically classified using a risk matrix framework, categorizing risks from low to high levels to prioritize appropriate mitigation measures. The risk assessment identified several high-risk incidents, particularly those categorized under accident codes A1, A3, B3, B4, B5, C3, C4, D1, D5, E1, E2, E3, E4, and E5. Following the risk assessment, targeted mitigation strategies were implemented to address workplace hazards across various job functions. These measures included the mandatory use of personal protective equipment (PPE) tailored to specific tasks, alongside strict adherence to established safety protocols and warning systems to prevent occupational accidents. The findings highlight the necessity for continuous safety monitoring, employee training, and a proactive risk management approach to ensure a safer working environment.

Abstract

Gelombang permukaan laut adalah salah satu fenomena yang sangat kompleks dan mudah berubah dibandingkan dengan arus dan pasang surut, sehingga untuk memahami secara menyeluruh tentang karakteristik gelombang permukaan laut merupakan hal yang sulit. Gelombang tersebut pada dasarnya adalah gelombang acak karena berbagai macam jenis gelombang dengan frekuensi tertentu yang berposisi satu sama lainnya. Sumber pembangkit gelombang tersebut terutama adalah angin, sehingga sering disebut dengan Gelombang Angin (Wind Waves). Untuk mendapatkan data tinggi gelombang dan suhu permukaan air laut dari berbagai sumber pembangkit gelombang memerlukan alat yang memadai untuk memperoleh datanya. Pada dasarnya ada beberapa jenis alat yang dapat dipergunakan baik di dalam dan di luar untuk memenuhi kebutuhan data tersebut, namun umumnya memerlukan biaya yang tidak sedikit. Sering terjadi bahwa alat yang diperlukan tidaklah sekompleks keperluan untuk pengadaan suatu penelitian yang sederhana, hanya membutuhkan satu atau dua parameter, misalkan untuk mencari data tinggi gelombang dan suhu diperlukan parameter data berupa tinggi air dan waktu, oleh karena itu pembuatan instrument bangunan laut dapat memenuhi kebutuhan untuk pemenuhan data sangat membantu. Pada riset ini, diharapkan dalam hitungan detik dapat diperoleh beberapa data gelombang berupa tinggi permukaan air dan suhu permukaan air laut pada waktu pengambilan datanya secara real time dan up to date.
