Abstract

Biogas adalah salah satu energi bahan bakar gas yang diperoleh dari degradasi anaerobik bahan-bahan organik oleh bakteri dalam lingkungan bebas oksigen. Digester portabel ini mampu menghasilkan biogas yang utamanya mengandung gas metana (CH4) dan gas ikutan lainnya. Proses pembentukan biogas khususnya gas metana pada digester dimonitor dengan sensor gas metana secara real time berbasis Internet of Things (IoT). Hasil pengukuran konsentrasi gas metana yang dilakukan selama 38 hari pada temperatur rata-rata 37,46°C, nilai konsentrasi terus meningkat sampai dengan hari ke 29, dengan konsentrasi gas sebesar 170.564,02 ppm atau persentase gas sebesar 71,07%. Pada hari ke 29 gas metana dalam digester sudah layak dimanfaatkan, dan untuk menjaga kontinyuitas produksi gas metana, setiap hari bahan baku biogas perlu ditambahkan ke digester sesuai kapasitas. Kata Kunci : Biogas, Digester.

Abstract : This study aims to analyze the improvement of service quality and commitment to the profession through strengthening Organizational Citizenship Behavior (OCB), job satisfaction, and self-efficacy. Optimal service quality and commitment to the profession are key factors in improving organizational performance, especially in the public service and education sectors. OCB as an extra-role behavior carried out voluntarily by employees is expected to be a driving factor in improving service quality and commitment to the profession. In addition, high job satisfaction and strong self-efficacy also play an important role in strengthening OCB. This study uses a quantitative approach with a survey method on employees in the public service sector. The results of the study indicate that OCB, job satisfaction, and self-efficacy significantly contribute to improving service quality and commitment to the profession. The implications of this study are expected to provide insight for organizational management in developing performance improvement strategies by strengthening these factors.

Abstract

The research aims to produce strategies and ways to improve lecturers' creativity through efforts to identify the magnitude of the direct and indirect influence of Transformational Leadership, Empowerment, Effectiveness and Utilization of ICT, and Work Motivation. This study uses a survey method and path analysis techniques, which are then subjected to SITOREM analysis. The population in the study amounted to 269 people, and a sample was taken randomly of 215 lecturers using the Taro Yamane formula. The results of the study prove that there is an influence of Transformational Leadership (by1 = 0.184), EmpowermentEmpowerment (by2 = 0.163), Effectiveness and Utilization of ICT (by3 = 0.275), and Work Motivation (by4 = 0.148) on Lecturer Creativity. SITOREM analysis proves that increasing creativity is done by improving weak indicators, namely the courage to take risks and work on complex things, developing or maintaining indicators of developing something new and different, providing problem-solving, and openness to new ideas. Transformational leadership is done by improving weak indicators, namely encouraging novelty, having charisma, having consideration, and providing inspiration. The implications of this research suggest that higher education institutions in Indonesia should prioritize the development of transformational leadership styles, empower faculty members, and invest in ICT tools to enhance work motivation, ultimately fostering a creative and innovative academic environment.

Abstract

This study aims to formulate effective strategies for improving teacher service quality through a multi-factor approach, namely Organizational Citizenship Behavior (OCB), interpersonal communication, organizational climate, and work motivation. Teacher service quality is an important indicator in the continuous improvement of education quality. The research method used is a quantitative approach with an explanatory causal design. Data were collected through questionnaires administered to teachers from various educational levels and analyzed using path analysis techniques. The results of the study indicate that OCB, interpersonal communication, organizational climate, and work motivation significantly and simultaneously influence the improvement of teacher service quality. OCB acts as a mediating factor that strengthens the influence of other variables on service quality. The practical implications of these findings highlight the importance of strengthening organizational culture, interpersonal communication training, and reward and motivation systems to promote teacher professionalism. An integrative strategy based on strengthening organizational behavior and a humanistic approach is recommended as a model for improving teacher service quality in the Indonesian educational context.

Abstract

Culinary small and medium enterprises (SMEs) play a vital role in Indonesia’s economy, contributing to GDP, employment, and community income. This dissertation research is significant as it identifies sustainability challenges resulting from low komitmen terhadap organisasi, influenced by variables such as perceived organizational support and creativity, with work motivation acting as a mediating factor. Moreover, there has been a lack of specific studies addressing this issue. The objective of this research is to analyze the influence of the three variables on komitmen terhadap organisasi and to formulate strategic approaches to enhance the sustainability of culinary SMEs in Bogor City.Seven hypotheses are proposed, examining the influence of perceived organizational support and creativity on work motivation and komitmen terhadap organisasi, as well as the mediating role of work motivation in these relationships. The novelty of this research lies in its strategic framework for enhancing komitmen terhadap organisasi to ensure business sustainability and its integration of the three exogenous variables into a validated analytical model. A mixed-method approach was employed, involving 230 employee respondents from Bogor City, collected between December 2023 and July 2024. The findings reveal that perceived organizational support affects komitmen terhadap organisasi through the mediation of work motivation. Additionally, both creativity and work motivation have a direct influence on komitmen terhadap organisasi. Furthermore, five strategic recommendations were developed to support the sustainability of culinary SMEs. It is expected that the results of this dissertation can serve as a foundation and guide for academics, entrepreneurs, and policymakers in formulating more effective policies to improve the sustainability and competitiveness of culinary SMEs at both the national (Bogor and Indonesia) and international levels.
