Dye-Sensitized Solar Cell (DSSC) is a solar cell unit that work based on electrochemical principle which convert the sun radiation into electricity. DSSC uses TiO2 semiconductor material for coating with spin coating method. The purpose of this research is to make a DSSC prototype using of Malabar melastome fruit (Melastoma Malabathricum L.) as dye and also to observe the impact of waterâ€™s volume and soaking duration of TiO2 coating on the produced voltage. The DSSC is constructed with a layering system (sandwich) which consists of working electrode and counter electrode. The working electrode is made by using FTO glass (2.5 x 2.5 cm2) which is coated with TiO2 paste that made by mixing 0.5 gram TiO2 powder in 4 ml ethan ol (1:8). The electrode is sintered under temperature in 350oC for 15 minutes and then soaked in dye liquid with volume of solvent fraction in dye dilution which are ; without dilution (100%); diluted once (50%); and diluted twice (25%) for about 10 minutes, 2 hours and 24 hours. This electrode is then given two droplets of 0.05 M electrolyte. After that the counter electrode is made by using FTO glass coated with carbon from candleâ€™s fire. The fabrication of DSSC is done by sticking both of the FTO glasses up. Melastome Malabar extract as dye is shown to contain anthocyanin, proven with a maximum wavelength of 515 nm. DSSC prototype generated by variation of 24 hours dye soaking duration and without dilution (100%) gave the highest voltage with the solar energy-to-electricity conversion of 1.026 volt/cm2 and when illuminated with LED lamp gave 0.595 volt/cm2. The morphology of TiO2 layer show a porous surface that is conducive to the absorption of dye. The level of adhesion obtained from the best samples showed good adhesion qualities (3B)Keywords: DSSC, LED, melastome malabar l, sunlight, voltage

Purpose of the study: This study aims to evaluate the quality of items in retention and transfer tests related to additive and addictive substances. Using Rasch modeling, the study seeks to enhance the management of learning evaluations and improve our understanding of student abilities and question quality. Methodology: The research utilizes the Rasch Model to analyze retention and transfer test instruments on science topics involving additives and addictive substances. Conducted with Winstep software, the analysis focuses on the performance of 92 purposively sampled 8th-grade students during their first semester of junior high school. The study examines retention and transfer abilities, comprehensively evaluating the test items. Main Findings: The Winstep program analysis reveals that, according to the Rasch model, the average ± MNSQ Outfit values for both items and persons are 0.92. The Outfit ZSTD values for items and persons are -0.12 and -0.01, respectively. The instrument's reliability, measured by Cronbach's alpha, is 0.60, indicating moderate reliability. The research findings demonstrate that each item in the instrument is valid and reasonably reliable, with all 20 items deemed suitable for assessing student performance in retention and transfer tests. Novelty/Originality of this study: This study offers a detailed examination of retention and transfer test instruments' quality using the Rasch Model, providing valuable insights for enhancing the accuracy and reliability of these assessment tools. The research significantly improves educational assessments in science education, particularly in evaluating students' understanding of additives and addictive substances.

Pengabdian ini bertujuan untuk mengkaji kemampuan siswa dalam “Menulis Puisi”. Penulis dapat mengenalkan pembelajaran materi menulis secara spontan. Dari hasil kegiatan ini siswa dapat mengembangkan kreativitas dan imajinasinya yang kemudian dikembangkan menjadi sebuah puisi, memberikan motivasi yang terdapat masalah yang terjadi dalam kehidupan sehari-hari, serta menumbuhkan sikap berani mengeluarkan ide atau gagasan mengenai suatu masalah yang akurat. Adapun tahapan maupun proses kreatif ada empat, yakni (1) persiapan, (2) inkubasi, (3) iluminasi, dan (4) verifikasi. Ini bisa dilakukan dengan pengayaan materi, mencari momen-momen puitik yang bisa menyentuh perasaan. Ide atau bahan penulisan bisa didapat dan digali dari mana saja. Kemunculannya bisa dilakukan dengan mengasah sensitivitas, pengalaman, imajinasi, dan bisa diperkaya dengan kegiatan membaca, mengamati, atau mencari momen-momen puitik. Upaya-upaya pengayaan bahasa perlu dilakukan, misalnya dengan pengayaan penguasaan kosakata, pengayaan bacaan-bacaan, terutama puisi, pengayaan dalam membentuk kata atau frase, dst.

Microplastics (< 5 mm) have the potential to be a threat to organisms. However, the study of microplastic contamination in conservation areas, especially in Indonesia, is still limited. The Sukamade is a conservation area that is potentially contaminated by microplastic. This study aims to detect microplastic contamination in fish caught in the Sukamade shoreline as an early warning of the potential threat to biodiversity. The study was conducted from September to December 2022. The methods used include: 1). Fish sampling, 2). Dissection and removal of the gills and gastrointestinal tract; 3). Microplastic characterization based on sizes, shapes, and colors; 4). Data analysis. This is the first report that 451 microplastic particles were detected in four fish caught from the Sukamade shoreline: two individuals of Senangin fish (Eleutheronema sp.), one individual of Lemuru fish (Sardinella sp.), and one individual of Lowang totol fish (Trachinotus sp.). The presence of microplastic in the gastrointestinal tract of fishes shows the possibility of microplastic translocation in tissue and another tropic level, causing health problems in organisms and the community as a constituent of biodiversity.

Penelitian ini bertujuan unttuk menganalisis gaya penulisan karya tulis ilmiah dan jurnalistik, penelitian ini membahas perbandingan gaya penulisan antara karya tulis jurnalistik dan ilmiah, dua bentuk tulisan yang memiliki tujuan dan audiens yang berbeda. Karya tulis jurnalistik cenderung mengedepankan kecepatan, kejelasan, dan daya tarik untuk menarik perhatian pembaca, dengan penggunaan bahasa yang sederhana dan langsung. Sebaliknya, karya tulis ilmiah menekankan ketelitian, sistematika, dan argumentasi yang kuat, menggunakan terminologi khusus dan struktur yang lebih formal. Metode penelitian yang digunakan adalah studi kualitatif dengan pendekatan deskriptif-analitis. Data dikumpulkan melalui studi pustaka terhadap berbagai jurnal ilmiah survey dengan total 74 responden yang terdiri dari mahasiswa UIN Sultan Maulana Hasanuddin Banten dan mahasiswa dari perguruan tinggi lainnya. Hasil penelitian menunjukkan bahwa 89,2% mahasiswa pernah menulis karya tulis jurnalistik dan ilmiah. Namun, 14,9% mahasiswa masih belum memahami perbedaan antara artikel, feature, news, esai, makalah, dan opini. Selain itu, 89% mahasiswa mengalami kesulitan dalam mencari data ketika menulis karya tulis jurnalistik dan ilmiah.

Some pregnant women may experience discomfort in the third trimester due to physiological reasons. Urination, pain in the pit of the stomach, weariness, and pain in the back and waist area are common complaints. A pregnant woman's psychology changed from anxiety and stress to a condition-conceived baby till she was terrified to confront labour. Inconvenience during pregnancy, if not well managed, can cause psychological distress in the mother. Prenatal yoga can help pregnant women who are nervous about their pregnancy overcome their pain.The goal of this review's scoping is to examine the usefulness of deep prenatal yoga in overcoming changes in physiological causes of discomfort in the third trimester of pregnancy. In the article, there is a scoping review. The PRISMA approach is used to identify published articles over the last five years (2019-2023) via ProQuest, SAGE Journal, Science Direct, and Cochrane and produce eight suitable journals. According to the findings, practising yoga during pregnancy can help moms overcome a variety of disruptions or inconveniences that can occur during the third trimester of their pregnancy. Prenatal yoga is a non-pharmacological therapy that can be administered to a pregnant mother in her third trimester to improve sleep quality, reduce anxiety, relieve back pain, and facilitate the process of labour stage II.
