This study intended to create a sea wave simulator to find out the potential of ocean wave power plants. To achieve the objective, this study used two systems: generation and reading. Generation used a DC motor as a drive from sea waves, while readings employed an IMU-GY86 sensor for readings of altitude and energy potential generated. The result of this study is that air and air pressure affect the results of measuring the wave height of seawater. Air pressure is inversely proportional to the elevation of a place: the higher the area, the lower the air pressure. The highest potential energy density of seawater waves amounts to 2405.33 J/m2, and the lowest was 550.18 J/m2, with an average value of seawater wave density energy of 1342.41 J/m2.
— Indonesia masih menghadapi masalah dalam pembangunan bidang energi. Ketergantungan terhadap energi fosil bisa dibilang masih cukup tinggi. Pemanfaatan energi terbarukan dapat dikatakan belum berjalan sebagaimana mestinya. Salah satu upaya yang dapat dilakukan yaitu dengan energi alternatif. Pembangkit listrik dari kayuhan pedal sepeda statis dapat menjadi salah satu energi alternatif yang dapat membangkitkan energi listrik sederhan. Penelitian ini bertujuan membuat sepeda statis sebagai pembangkit listrik sederhana untuk keperluan perangkat elektronik sederhana. Alat ini bekerja dari kayuhan sepeda untuk memutar generator DC yang kemudian disalurkan pada SCC. Hasil tegangan listrik disimpan ke akumulator dengan watt meter sebagai indicator tegangan dan arus keluaran generator. Penelitian ini didapatkan RPM minimal untuk menyalakan watt meter pada RPM 50 pada kayuhan sepeda yang menghasilkan tegangan 6,09V. RPM maksimal pada 85 RPM dengan tegangan 13,61V, dimana akumulator akan terisi pada saat tegangan sudah lebih dari 12V.
The lighting system is one of the aspects of assessing the function of the building. The building lighting system is included in the health aspect of the building. To achieve proper function, the building lighting system must meet the illumination value of each room according to the type of utilization in accordance with SNI 6197:2011, SNI 6197:2011, SNI 03-2396-2001, dan SNI 03-6575-2001. This study aims to analyze the lighting system in the Gedung Kuliah Bersama at the Politeknik Negeri Cilacap. This study uses a quantitative method by comparing the amount of light intensity based on field measurements, calculation results, and the SNI 6197:2011 standard. Based on the results of observations, data processing, and measurements, it was found that there were still some rooms in the Gedung Kuliah Bersama that did not meet SNI. Rooms that have fulfilled SNI include classrooms, library rooms, language laboratories, lecturer transit rooms, multipurpose rooms, terrace, and warehouses. It is necessary to carry out maintenance and repair of lamps for rooms that do not meet SNI. Maintenance and repair of lighting systems are carried out by replacing, adding, and/or repositioning lamps.
One of the most effective digital marketing strategies today is co-creation marketing. Co-creation places consumers as parties who actively share to create value or products. This study aims to determine the form of value co-creation in Pergiramame Tour & Travel with the DART model (Dialogue, Access, Risk Assessment, Transparency) as a strategy in innovation and product development while evaluating value co-creation in Pergiramame Tour & Travel with the DART model. . The results of the study show that Pergiramame Tour & Travel has been very good at applying the DART concept to create corporate image and value. Although some things can be maximized again, each model makes a positive contribution and is believed to be able to contribute sustainably in strengthening the company, especially in the current era of society 5.0.
