Recently, quadrotor-based drones have attracted a lot of attention because of their versatility, which makes them an ideal medium for a variety of applications, e.g., personal photography, surveillance, and the delivery of lightweight packages. The flight duration of a drone is limited by its battery capacity. Increasing the payload capacity of a drone requires more current to be supplied by the battery onboard a drone. Elevated currents through a Li-ion battery can increase the battery temperature, thus posing a significant risk of fire or explosion. Li-ion batteries are suited for drone applications, due to their high energy density. There have been attempts to use hydrogen fuel cells onboard drones. Fuel cell stacks and fuel tank assemblies can have a high energy to weight ratio. So, they may be able to power long duration drone flights, but such fuel cell stacks and associated systems, are usually extremely expensive. Hence, this work proposes the novel use of a less expensive, low capacity, metal hydride fuel stick-powered fuel cell stack as an auxiliary power supply onboard a drone. A primary advantage of this is that the fuel sticks can be used to cool the batteries, and a side effect is that this slightly reduces the burden on the onboard Li-ion battery and provides a small increment in flight time. This work presents the results of an experimental study which shows the primary effect (i.e., decrease in battery temperature) and the secondary side effect (i.e., a small increment in flight time) obtained by using a fuel cell stack. In this work, a metal hydride fuel stick powered hydrogen fuel cell is used along with a Li-ion battery onboard a drone.
Traditional way of financing has been shifted by financial technology. This situation is supported by demands coming from unbanked people and small and medium enterprises (SMEs). By the end of 2016, only 36% of Indonesian adults have an account at the formal financial institution, while 49 million SMEs units were not bankable as shown on Indonesia Fintech Report 2016. As one of financial technology (fintech) players in Indonesia, KoinWorks provides peer-to-peer (P2P) lending system. However, because of the new concept of financial industry, people still have a low awareness of fintech institution, especially Koinworks. This company aims to acquaint to public the advantages of fintech institution utilizing public relations (PR) roles and strategies. Its PR department is expected to reach communication goals, including increasing the brand awareness. This research employed qualitative approach and the data were primarily collected through in-depth interviews with four purposively-chosen participants. This study concluded that all Marketing PR strategies were executed by marketing and public relations and strategies that were optimized to build the brand awareness were events, news, speeches, and sponsorships.
The purpose of this study was to analys the impact of organizational culture, self-efficacy and competence on Organizational Citizenship Behavior (OCB) and job performance of Production Department employees at PT. Indoprima Gemilang Surabaya. A structured questionnaire disseminated to 120 employees as sample, sampling method using random system. Analyzed using SEM with Amos v.24. The results of this study indicate that organizational culture and self-efficacy have a significant on Organizational Citizenship Behavior (OCB); no significant competence on Organizational Citizenship Behavior (OCB); the results also showed that organizational culture, self-efficacy and competence significantly influence employee performance in the Production section of PT. Indoprima Gemilang Surabaya.
The tourism sector is one of the sectors to increase the economy of the state. Banten is one of the province in Indonesia that has the potential to develop the tourism sector since Banten has Tanjung Lesung as Special Economic Zone. PT Banten West Java Tourism Development (BWJTD) as a developer of Tanjung Lesung has to manage various strategies to increase the number of tourists. This study explained the public relation strategies of PT BWJTD to increase the number of tourists to Tanjung Lesung. It used a model of strategic planning for public relations from Ronald D. Smith for analysis, known as The Nine Steps of Strategic Public Relations. The model includes research formative, strategy, tactics, and evaluation. The data were collected using in-depth interviews with three key informants, observation on tactics, and documentation related to Tanjung Lesung. Based on the findings, it can be concluded that the public relation strategies used by PT BWJTD are the proactive strategies. Keywords: Tourism, Tanjung Lesung, Strategic Planning, Public Relations
Pemerintah Indonesia memutuskan untuk melakukan program vaksinasi Covid-19 untuk memutus mata rantai penyebaran COVID-19 di Indonesia. Penelitian ini bertujuan untuk mengetahui persepsi pekerja terhadap vaksinasi COVID-19. Penelitian ini dikembangkan dengan menggunakan metode kualitatif dan pendekatan fenomenologis. Tujuh informan telah mengikuti wawancara mendalam dan penelitian ini menyimpulkan bahwa para informan melihat vaksinasi COVID-19 sebagai antibodi untuk mencegah Covid-19. Mereka berkomitmen mengikuti vaksinasi setelah Presiden Jokowi menjadi orang pertama yang mendapatkan vaksin Covid-19 dosis pertama di Indonesia.
