Abstract

The need for environmentally friendly marine transportation continues to increase, especially in tourist areas such as Penyengat Island, Tanjungpinang, Riau Islands. In the local context, the design of electric boats has not been widely developed for small islands in Indonesia, even though the potential and urgency for its application is very high. Geographical constraints, limited charging infrastructure, and a lack of technical data are the main obstacles. This research focuses on the design and construction of an electric-powered tourist boat prototype with an asymmetrical catamaran hull type as an effort to support a sustainable transportation system. The boat design applies an asymmetrical catamaran hull configuration to improve sailing stability and energy efficiency. The propulsion system is controlled via a wireless PS2 joystick integrated with an ESP32 microcontroller, supported by a 24V DC motor powered by lithium-ion batteries and solar panels as a supplement. Test results show that the boat can operate stably with remote control, good energy efficiency, and zero emissions during operation. Some technical challenges encountered include limited operational duration due to battery capacity and high sensitivity of electronic components to water exposure. Overall, this prototype has great potential for further development as an environmentally friendly alternative for maritime transportation system. The stable catamaran hull design provides advantages in terms of comfort and safety, especially in calm or shallow waters. The electric propulsion system used has proven to be efficient and responsive, supported by a remote control mechanism that is easy to operate via a wireless joystick

Abstract

The increase in synthetic dye waste from the textile industry causes significant environmental pollution, prompting the need for environmentally friendly dye alternatives. One potential source is the bark of the Rhizophora mucronata mangrove tree, which is rich in tannins and phenolic compounds. This article describes the socialization and training activities on the use of mangrove bark as a natural dye in ecoprinting with an innovative combination of pounding and steaming techniques in Bintan Buyu Village, Bintan Regency, Riau Islands. The implementation methods included socialization on the basic concepts of ecoprinting, introduction to the ecological and economic potential of mangroves, and practical training on ecoprinting. The training process included mordanting fabric with alum, basic dyeing using mangrove bark decoction, leaf printing (pounding), and color fixing (steaming). The pounding technique produced clear and detailed leaf motifs, while the steaming technique increased color fastness to prevent fading. The results of the activity showed high enthusiasm among participants, as seen from their active participation in discussions, practice, and the quality of the works produced. The participants' ecoprint products featured a combination of natural brown colors with sharp and aesthetic patterns of various leaves. This activity succeeded in increasing the community's knowledge, skills, and awareness of the sustainable use of local resources. The combined pounding– steam technique has proven effective in creating environmentally friendly ecoprints with good pattern quality and color fastness, while also opening up opportunities for creative businesses based on the potential of local mangroves.
