This study evaluates longboat operational safety on the Sampit–Pagatan route in East Kotawaringin, Central Kalimantan. The route is a vital link for remote areas where road infrastructure is lacking. Field data indicate frequent longboat accidents between 2021 and 2024, some fatal, due to limited safety equipment, insufficient crew competence, and substandard vessel seaworthiness. Using a qualitative and quantitative descriptive approach—through field surveys, observations, and regulatory reviews—this study explores the root causes and their implications. Findings highlight a significant correlation between crew knowledge and compliance with safety equipment requirements. This research offers innovation-based safety management recommendations for improved inland navigation standards.

Sediment dredging at the Water Putih Crossing Port (1.4675° N, 102.1167° E) produced 68,400 m³ of material (60% mud, 30% sand, 10% gravel) that could potentially be utilized for sustainable transportation infrastructure. This study analyzes material characteristics, economic feasibility, and environmental impact through a mixed approach (quantitative and qualitative). Laboratory test results show that sand and gravel meet the standards of road construction materials (CBR 25-45%), while mud (CBR 3%) requires stabilization. A Life Cycle Assessment (LCA) analysis revealed that the use of sediment as a road material generates an income of USD 20/m³ with the lowest carbon emissions (5.2 kg CO₂/m³), compared to coastal reclamation (4.8 kg CO₂/m³) or waste disposal (12.3 kg CO₂/m³). The study emphasizes the importance of substituting cement with geopolymers to reduce emissions by up to 40% as well as the development of a green logistics model. These findings form the basis for policy recommendations for sustainable sediment management, supporting the circular economy and the Sustainable Development Goals (SDGs) targets in the infrastructure sector.

One solution to make the combustion that occurs in a motorbike closer to perfect is by utilizing the use of a Voltage Stabilizer. The performance of the Voltage Stabilizer is able to focus the electric current from the coil, so that the sparks emitted by the spark plugs are greater than before. Through the measurement results, in the condition of the Voltage Stabilizer installed, the lowest CO level was 0.72%vol, the lowest CO2 was 6.06%vol, the lowest HC was 1336 ppmvol occurred at an engine speed range of 5000 rpm. The lowest O2 level of 6.25%vol was obtained at an engine speed of 5000 rpm when the standard condition was without the Voltage Stabilizer installed. The highest O2 level obtained was 17.12%vol at an engine speed of 1000 rpm with the Voltage Stabilizer installed. The highest Torque (T) value was 8,722 Nm, and the highest Power (P) value was 8,414 PS at an engine speed range of 8000 rpm. Occurred when the Voltage Stabilizer was installed. With the installation of Voltage Stabilizer, it causes an increase in the Torque value of 11.93% and Power of 12.80% produced. The highest Fuel Consumption value of 0.642 Kg/h when the engine speed is in the range of 8000 rpm, occurs in conditions without the Voltage Stabilizer installed. The lowest Fuel Consumption value of 0.094 Kg/h when the engine speed is in the range of 1000 rpm, occurs in conditions with the Voltage Stabilizer installed. Furthermore, the installation of the Voltage Stabilizer causes a decrease in the Fuel Consumption value of 14.22%. This happens because the installation of the Voltage Stabilizer can stabilize the current and voltage obtained from the Battery/Accu to be distributed to the electrical components of the vehicle, so that there is efficiency in the vehicle's electrical supply, affecting emissions and fuel consumption produced.

The use of an Oil Catch Tank (OCT) is intended to optimize the clean air entering the intake manifold and reduce vehicle exhaust emissions. The main function of the OCT is to prevent oil particles or oil vapors from re-entering the intake system. Blow-by gases from the crankcase first enter the OCT tube, where they are trapped by a filter medium (steel wool), allowing only clean air to reach the combustion chamber. From the experimental results, across all OCT filter variations, the lowest CO levels were recorded at 1000 rpm, while the highest CO occurred at 3500 rpm. The highest CO level of 20.97% vol was found under standard vehicle conditions at 4500 rpm. The lowest HC value of 93.57 ppm vol was obtained using a 0.5-micron OCT filter at 5000 rpm. The highest torque and power values of 143 Nm and 108.65 HP, respectively, were achieved when using a 1-micron filter OCT at 6000 rpm. This study confirms that OCT installation can significantly reduce exhaust emissions and improve engine performance. These findings contribute to addressing global environmental concerns, particularly air pollution and climate change caused by the transportation sector. Furthermore, the results support the broader adoption of environmentally friendly automotive technologies, especially in enhancing combustion efficiency and emission control in internal combustion engine vehicles.
