Abstract

This study examines the effects of temperature and solar exposure duration on photovoltaic panel efficiency in tropical regions, using a case study at the PLN Institute of Technology's Solar Power Plant (PLTS) in Jakarta. The background highlights challenges in PLTS efficiency under tropical climates vulnerable to high temperatures and solar radiation fluctuations. The objective is to analyze the simultaneous impact of both factors during dry and rainy seasons. The method employs Partial Least Squares Structural Equation Modeling (PLS-SEM) with field data collected over 6 months (January-June 2025). Results reveal that temperature has a strongly significant negative effect on efficiency in both seasons (coefficient -1.128 for dry; -1.065 for rainy), while solar exposure shows smaller positive effects (0.361 for dry; 0.209 for rainy). A key finding is the dominant role of temperature regardless of season, whereas solar radiation remains significant even at low intensity. The study implies the need for panel cooling systems and climate-specific adaptation strategies to optimize PLTS in tropical areas.

Abstract

Pembangkit Listrik Tenaga Surya (PLTS) off-grid menjadi salah satu solusi penting dalam mendukung transisi energi terbarukan, khususnya di wilayah tropis urban seperti Jakarta. Kinerja sistem ini sangat dipengaruhi oleh faktor lingkungan, terutama intensitas radiasi matahari dan durasi penyinaran harian. Penelitian ini bertujuan untuk menganalisis pengaruh kedua variabel tersebut terhadap muatan listrik baterai PLTS sebagai penyimpan energi utama. Landasan teoritis mencakup konsep intensitas radiasi, durasi penyinaran, dan mekanisme pengisian baterai dalam sistem fotovoltaik, dengan metode analisis regresi linier dan nonlinier (logaritmik, kuadratik, dan kubik). Data yang digunakan diperoleh dari catatan operasional PLTS Institut Teknologi PLN selama periode Januari– Desember 2024, dengan total 366 hari observasi. Hasil analisis menunjukkan bahwa intensitas radiasi memiliki pengaruh positif dan signifikan terhadap arus listrik yang masuk ke baterai pada seluruh bentuk model regresi, sedangkan durasi penyinaran memberikan pengaruh positif namun tidak signifikan. Model nonlinier mengindikasikan adanya hubungan yang lebih kompleks, khususnya saat variabel suhu ambient dan kecepatan angin dimasukkan sebagai faktor mediasi, di mana pola pengaruhnya menunjukkan titik jenuh pada nilai tertentu. Kesimpulannya, intensitas radiasi merupakan faktor dominan dalam menentukan efisiensi pengisian baterai PLTS, sedangkan durasi penyinaran memiliki peran terbatas. Peningkatan kinerja sistem dapat dilakukan melalui integrasi pemantauan radiasi secara real-time, pemanfaatan teknologi prediksi cuaca, dan pemilihan baterai berkapasitas tinggi yang sesuai dengan kondisi iklim tropis.

Abstract

A business model is a strategic plan for creating, delivering, and retaining value, ensuring profitability and competitiveness. To thrive in a dynamic market, a company should harness its strengths and innovate its business model to address opportunities or challenges. Strong capabilities empower a firm to effectively implement business model innovation in response to market fluctuations. This quantitative study examines the role of a firm’s capabilities, which are dynamic capabilities and market orientation toward a business model innovation in Indonesia’s hotel industry after the pandemic. Inferential statistical analysis was conducted on two independent variables, dynamic capabilities, and market orientation, to examine their impacts on business model innovation as a dependent variable using Structural Equation Modelling with software Smart PLS 4. The samples included 492 general managers at three to five-star hotels in Indonesia who were used as respondents. They were selected using purposive sampling to examine two hypotheses. A five-point Likert-scale online questionnaire included thirty-two questions from seven dimensions covering two independent variables examined. The results of the T-test show that the firm’s capabilities, which are dynamic capabilities and market orientation, have significant effects independently on business model innovation, with each substantial value of p<0.05.  Dynamic capabilities affect business model innovation by 42.9%, followed by Market orientation, which contributes to business model innovation generation by 35%. Additionally, Importance-Performance Map Analysis (IPMA) identifies the practical contributions of firm capabilities, particularly highlighting the significance of proactive market orientation in influencing business model innovation.
