The purpose of this study is to optimize the potential of solar energy that releases light and thermal energy simultaneously by using a combination of PV and TEG technology. PV only absorbs photon light, where solar thermal is transmitted to the TEG module under the panel surface which is useful for maintaining temperature and increasing PV output power. The TEG module configuration was chosen to be circular with the diameter of the circle adjusting to the area of the solar PV panel. There are two PV panels used during the test, one panel is left without TEG and the other panel is installed with 12 TEG modules and on the cold side of the module is added a heat sink and circulating water fluid cooling to maintain the temperature of the cold side of the module. The test results show that the integration of PV-TEG increases the system output power by about 45% compared to PV alone. The PV surface temperature is more stable and tends to be even with the attachment of TEG and cooling with water, while without the hybrid, the PV temperature appears to be sinusoidal with a peak temperature of about 70°C compared to the hybrid only around 40 and 50°C. PV temperatures below 60°C are important to maintain PV performance for a long period

Numeracy ability is the ability to think logically and systematically in solving contextual problems based on data and numbers. However, students' numeracy ability in Indonesia, including in Central Java, is still relatively low. This study aims to determine the relationship between self-efficacy and mathematical connection ability simultaneously on students' numeracy ability on the material of arithmetic sequences and series in class X MANU 3 Ittihad Bahari Bonang Demak. This study uses a quantitative approach with a correlational method. The research sample was taken using a cluster random sampling technique, and two classes were obtained, namely class X.1 and X.2. The research instruments were in the form of a self-efficacy questionnaire and a descriptive test to measure mathematical connection and numeracy abilities. Data analysis was carried out using multiple linear regression tests using SPSS 25. The results of the study showed that there was a significant positive relationship simultaneously between self-efficacy and mathematical connection ability on students' numeracy abilities, with a coefficient of determination (R ²) value of 0.599. This means that the two independent variables contributed 59.9% to students' numeracy skills, while 40.1% was influenced by other factors. These results indicate the importance of the role of self-efficacy and mathematical connections in improving students' numeracy skills, as well as being the basis for further research to examine other factors that contribute to the development of numeracy skills.

Penelitian ini bertujuan untuk mengeksplorasi dinamika kemandirian wanita dalam peran rumah tangga dari perspektif Kompilasi Hukum Islam (KHI) dan kajian kitab Fathul Nizar. Dengan menggunakan metode penelitian kualitatif, penelitian ini menyelidiki fenomena dan isu terkini yang dihadapi oleh wanita Muslim dalam menjalankan tanggung jawab domestik mereka. Hasil penelitian menunjukkan bahwa meskipun KHI dan Fathul Nizar memberikan kerangka hukum yang mendukung peran wanita sebagai istri dan ibu, praktik di lapangan sering kali menunjukkan adanya konflik antara tuntutan domestik dan partisipasi dalam dunia kerja. Wanita sering kali mengalami stres akibat peran ganda yang mereka jalani, yaitu sebagai pengelola rumah tangga sekaligus pekerja. Selain itu, keterlibatan suami dalam mengasuh anak dan pembagian tugas rumah tangga masih terbatas, yang dapat menghambat kemandirian wanita. Penelitian ini juga menemukan bahwa akses terhadap pendidikan dan pelatihan sangat penting untuk memberdayakan perempuan dalam konteks ekonomi, sehingga mereka dapat berkontribusi secara finansial tanpa mengabaikan tanggung jawab domestik. Temuan ini diharapkan dapat memberikan wawasan bagi kebijakan pengembangan yang lebih mendukung kesetaraan gender dalam keluarga dan masyarakat.

Penelitian ini bertujuan untuk menganalisis penerapan dalil qath’i dan zhanni dalam inovasi al-uqūd al-murakkabah (multi akad) pada sistem perbankan syariah. Fokus kajian diarahkan pada bagaimana kedua jenis dalil tersebut dapat diharmonisasikan untuk mendukung pengembangan produk keuangan yang kompleks namun tetap sesuai dengan prinsip syariah. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif-analitis terhadap literatur klasik dan kontemporer, fatwa DSN-MUI, serta studi kasus pada produk multi akad di Bank Syariah Indonesia (BSI) dan BTPN Syariah. Hasil penelitian menunjukkan bahwa dalil qath’i berfungsi sebagai batas syariah yang tidak boleh dilanggar, khususnya dalam larangan riba dan gharar, sedangkan dalil zhanni memberikan fleksibilitas ijtihad bagi inovasi produk yang relevan dengan kebutuhan pasar modern. Kebaruan penelitian ini terletak pada penegasan relasi dialektis antara dalil qath’i dan zhanni dalam menciptakan produk multi akad yang kompetitif dan patuh syariah. Penelitian ini merekomendasikan agar regulator dan lembaga keuangan syariah memperkuat prinsip maqāṣid al-syarī‘ah dalam pengembangan produk serta menyusun pedoman inovasi akad berbasis kemaslahatan.

Lung cancer has the highest mortality rate of all cancers. In its advanced stages, this disease is associated with poor survival rates and quality of life. The most common subtype of lung cancer is adenocarcinoma which is frequently associated with mutations in the epidermal growth factor receptor (EGFR), a protein crucialfor cell proliferation. The presence of EGFR mutations plays a key role in targeted therapy using tyrosine kinase inhibitors (TKIs). Afatinib is a second-generation TKI that offers several advantages over the first-generation. Afatinib is effective against complex and uncommon EGFR mutations, making it a commonly usedoption for patients with lung adenocarcinoma. However, afatinib is also associated with a higher incidence of adverse drug reactions (ADRs) compared to other TKIs, which may impact therapeutic outcomes. This study aimed to assess the quality of life (QoL) of advanced lung adenocarcinoma patients with EGFR mutations andthe prevalence of ADRs associated with afatinib treatment at Dr. Sardjito General Hospital in Yogyakarta. The study employed an observational cross-sectional design. Prospective data collection was conducted for two months, from January to February 2025 at the Oncology Department following ethical approval. A totalof 15 patients were enrolled in this study. The most commonly identified ADRs were acne (45%), diarrhea (20%), paronychia (20%), and oral mucositis (15%). The mean QoL scores was 81.38 ± 10.01 for the functional scale, 15.93 ± 8.48 for the symptom scale, and 72.78 ± 19.53 for global health status.
