Abstract

This paper explores the concept of digitalization in critical sailing lines to manage ship-generated waves (SGW), with a focus on fishing boats. Indonesia, as a maritime nation, faces challenges due to the environmental impact of SGW, such as riverbank erosion, habitat disruption, and damage to marine infrastructure. The proposed digital framework integrates real-time environmental data, including tidal conditions, river currents, and water depth, with vessel parameters like speed and GPS tracking. This system aims to provide accessible information through websites and smartphone applications, enabling safer and more efficient navigation. The results highlight the importance of digitalization in enhancing maritime safety, reducing environmental damage, and improving operational efficiency for fishermen and port operators.

Abstract

Roof tiles play a vital role in the construction industry by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.
