Abstract

Altimetry satellite technology is used to regulate sea level. Observations are carried out every year to study the dynamics of sea level in the world. Sea level anomalies (SLA) in each region have different values and vary greatly. The main cause that increases from sea level is the thermal increase that increases from the mass of water from melting ice and glaciers on the surface of the earth. Therefore, this research aims to calculate the SLA from the SARAL / AltiKa satellite data and Jason's satellite series to study the variability of sea level in Indonesia's western sea, namely: the Java Sea, Karimata Strait and the South China Sea. From the research conducted, sea level rise obtained using SARAL / AltiKa satellite data in the range of -10 mm to 8 mm at a rate of decline of 0,459 mm / year. Meanwhile, Jason's series satellite data produces sea surface variations of around -2 mm to 11 mm at a rate of decline of 0,817 mm / year. From these two satellite observations, sea level decreases occur in the Java Sea, while in the Karimata Strait and parts of the South China Sea increasing sea level rise. In addition, this study uses research analysis to study the association of SLA data from SARAL / AltiKa and Jason satellite observations. The results of comparative analysis are very strong and in line with the estimated coefficient value of 0,9332.Keywords: Altimetri, Jason, Perairan Indonesia, SARAL/AltiKa, Sea Level Anomaly, Trend

Abstract

Traffic safety is a serious issue that directly impacts the security and well-being of the community, including in Bengkalis District. A survey involving 42 respondents from various age groups and backgrounds identified a number of risky driving behaviors, such as non-compliance with helmet use, high-speed driving, and negligence when crossing intersections. This data served as the basis for implementing a community service program focused on preventing risky behavior on the road. The program was designed with a data-driven approach that took into account local conditions and the behavioral characteristics of the local community. The implementation team designed and implemented an interactive educational session attended by 40 participants, consisting of motorcycle riders, students, and local community members. The educational materials included theoretical explanations, visual simulations, group discussions, and case studies relevant to the situation on the ground. This method aimed not only to convey information but also to build critical awareness regarding the risks and consequences of unsafe driving behavior. The results showed an increase in participants' understanding of traffic safety regulations and the importance of complying with safety signs and procedures. Several participants reported changes in attitudes, such as a commitment to always wear a helmet and reduce speed when driving. These findings indicate that relevant, participatory, and community-based educational interventions can be an effective first step in shaping safer driving behaviors. The program's sustainability is expected to be achieved through collaboration with schools, community organizations, and local government agencies, as well as the integration of traffic safety materials into educational curricula and community activities. This approach has the potential to create a culture of safe, disciplined, and sustainable driving in Bengkalis District, while also serving as a model intervention that can be replicated in other areas with similar challenges.

Abstract

The household toilet assistance program is one of the local government’s efforts to improve access to adequate sanitation in rural areas. In 2025, the Bengkalis Regency Government implemented a toilet assistance program in several villages, including Penebal Village. This study aims to evaluate the technical compliance of government-assisted toilets in Penebal Village with Indonesian National Standard (SNI) 2398:2017 and to formulate recommendations for septic tank redesign based on the applicable standard. The study employed a descriptive–evaluative method through field observations of the standardized toilet type constructed under the assistance program. Evaluation parameters included toilet floor and wall conditions, type of toilet fixture, air ventilation, septic tank dimensions and materials, gas ventilation system, wastewater infiltration system, and the distance between septic tanks and clean water sources. The observed conditions were then compared with the technical requirements stipulated in SNI 2398:2017 and related sanitation regulations. The results indicate that several components of the government-assisted toilets comply with the technical standards, such as the use of water-seal toilets, septic tank compartmentation, and watertight construction materials. However, non-compliance was identified in floor and wall impermeability, ventilation systems, septic tank dimensions, and the absence of standard-compliant wastewater infiltration systems. Based on these findings, improvements through a septic tank redesign in accordance with SNI 2398:2017 are recommended to ensure optimal and sustainable sanitation system performance.
