The increasing number of motor vehicles in Indonesia produces repetitive mechanical loads on road surfaces that are rarely converted into useful energy. This study designs and evaluates a piezoelectric energy-harvesting speed bump intended to support low-power street lighting. The prototype integrates 25 piezoelectric discs (50 mm diameter) connected in series, an AC–DC bridge rectifier, a 2.7 V/500 F supercapacitor for short-term storage, and a DC–DC step-up converter to charge a 12 V battery. Field tests used a motorcycle at speeds of 5, 10, and 15 km/h with rider masses of 48, 70, and 79 kg; each condition was repeated ten times and averaged. Output voltage, current, and electrical energy per pass were measured after rectification. Results indicate that higher speed and mass increase electrical output, with a peak energy of 0.021 J at 15 km/h and 70 kg and an estimated conversion efficiency of about 0.20%. After repeated charging cycles, stored energy powered a 12 V/20 W LED lamp for several minutes. The proposed integration of series piezoelectric elements with supercapacitor buffering and step-up regulation demonstrates a feasible micro-energy harvester for traffic-dense areas and provides a basis for durability and scaling studies. Future work addresses packaging, fatigue, and multi-vehicle loading.

Indonesia has a variety of traditional Nusantara cakes that are not only unique, but also appetizing. However, along with the development of the times, traditional Nusantara cakes are increasingly rare. Only a handful of sellers are still loyal to selling these snacks. One of the reasons for the decline in the popularity of these traditional cakes is the growing perception among the public, especially children, who consider these cakes "old-fashioned." Many elementary school-aged children are now more interested in modern snacks, such as donuts, cakes, or candy, than traditional cakes such as klepon, onde-onde, or layered cakes. Therefore, this study aims to design a board game as a fun and educational interactive media, with the hope of introducing and preserving traditional Nusantara cakes to children aged 8-11 years. The methods used in this study include an in-depth analysis of relevant traditional cakes, development of game mechanics that are appropriate to the target age, and prototype trials to see children's responses and involvement in this game. Thus, this research is expected to provide a significant contribution to efforts to preserve culture while promoting a deeper understanding of the culinary richness of the archipelago among the younger generation, so that this tradition can continue to be passed down from one generation to the next.

The issue of illegal parking in various urban areas often causes traffic congestion, disorder, and economic losses for official parking operators.

The primary focus of this research was to create a Smart Count of Vehicle Loading Prototype for ships, with an emphasis on monitoring and tallying vehicles boarding and disembarking from ships based on their weight. Microcontrollers, such as the ESP32, were utilized for the counting process and to determine if the ship's cargo weight exceeded its maximum capacity. The main objective was to prevent overloading on ships, which could lead to accidents during voyages or while vehicles were being loaded onto the ship. To achieve this goal, weight and distance sensors were installed on the ship and controlled by the microcontroller, allowing for accurate monitoring of the quantity and categories of vehicles being loaded. After designing and testing this prototype device, it has become a new technological innovation that makes monitoring the weight and quantity of cargo on ships easier and more efficient. This is supported by the fact that each sensor's readings can work well with an average error rate below 2%. Additionally, the maximum communication range between the Blynk IoT application and the ship system can reach up to 20 meters.

Indonesia is a country with a high level of earthquake vulnerability, thus demanding innovation in building structural engineering that is not only safe but also environmentally friendly. In the context of sustainable development, bamboo as an abundant local material is starting to gain attention as an alternative to conventional materials. Bamboo, when processed into composites in the form of fibers or in combination with thermoplastic and thermoset polymers, has been proven to have superior mechanical properties, including tensile strength, stiffness, and resistance to chemical degradation. In addition, the characteristics of water absorption that are controlled through certain treatments make bamboo composites more competitive compared to synthetic materials. The application of bamboo composites in construction is not only limited to new materials in structural elements, but also effective in retrofitting methods. For example, recent research shows the potential of bamboo composites in strengthening reinforced concrete beams and improving the performance of frame systems in earthquake-resistant structures. In line with this, seismic design regulations and standards such as the comparison between SNI 1726:2012 and SNI 1726:2019 demonstrate the importance of adapting structural designs to local seismic conditions. The integration of bamboo composite materials with structural capacity analysis, numerical simulation, and pushover analysis methods has yielded promising results for improving building resilience to dynamic loads. Beyond technical aspects, this approach also supports environmental objectives. Several studies have even developed eco-friendly home prototypes utilizing innovative material combinations, including geopolymer blocks and natural fibers. Thus, the use of bamboo composites not only provides a technical solution to earthquake challenges but also contributes to global efforts to reduce the carbon footprint of the construction sector.
