Abstract

Sun exposure can cause adverse effects such as skin damage by inducing photoaging, photocarcinogenesis, even cause skin cancer through its direct effect on target cells. Nowdays, sunscreen products are dominated by synthetic chemicals that can have side effects, so it is necessary to return to natural ingredients to overcome them. The aim of this study was to observe the sunscreen activity of a combination of Curcuma longa and Haematococus pluvialis extracts in vitro using a UV-Vis spectrophotometer. The sunscreen activity was tested by measuring the absorbance of the combination of Curcuma longa and Haematococus pluvialis extracts in a ratio of 3:1 (C1), 1:1 (C2), and 3:1 (C3) at a concentration of 100 ppm and a wavelength of 290-320 nm. The absorbance data is then determined by the SPF value using the Mansur equation. Sunscreen activity is indicated by the SPF value, the greater the SPF value, the better the sunscreen activity. The results show that the highest SPF value is the combination sample C3 with  SPF value of 31.51 and is classified as ultra protection sunscreen. AbstrakPaparan sinar matahari dapat menyebabkan efek buruk seperti kerusakan kulit dengan menginduksi photoaging, photocarsinogenesis bahkan dapat menyebabkan kanker kulit pada manusia melalui pengaruh langsung pada sel sasaran. Produk tabir surya saat ini didominasi oleh bahan-bahan kimia sintetis yang dapat memberikan efek samping, sehingga perlu kembali ke bahan alami untuk mengatasinya. Tujuan penelitian ini adalah untuk melihat aktifitas tabir surya kombinasi ekstrak kunyit (Curcuma longa) dan alga hijau (Haematococus plivialis) secara in vitro menggunakan spektrofotometer UV-Vis. Pengujian aktivitas tabir surya dengan mengukur absorbansi kombinasi ekstrak Curcuma longa dan Haematococus pluvialis dengan perbandingan 3:1 (C1), 1:1 (C2), dan 3:1 (C3) pada konsentrasi 100 ppm dengan panjang gelombang 290-320 nm. Data absorbansi selanjutnya ditentukan nilai SPF nya menggunakan persamaan Masur. Aktifitas tabir surya ditunjukkan dari nilai SPF, semakin besar nilai SPF maka aktifitas tabir suryanya semakin bagus. Hasil menunjukkan nilai SPF tertinggi yaitu sampel kombinasi C3 dengan nilai SPF sebesar 31,51 dan digolongkan perlindungan tabir surya proteksi ultra.

Abstract

The continuous utilization of fossil energy has resulted in serious impacts on the environment and the Earth. In order to reduce the use of environmentally harmful fossil energy, UIN Raden Intan Lampung, as one of the eco-friendly campuses in Indonesia, is committed to transitioning to renewable energy, particularly through the use of solar panels to generate electrical energy. The aims of this research were to evaluate the effectiveness and utilization of solar panels in the male dormitory building of Ma’had Al-Jami’ah UIN Raden Intan Lampung in meeting electricity needs. The research methodology involves observation, interviews, and questionnaire completion as data collection efforts. The research findings indicate that solar panels generate an average of 381.33 watts of electricity per day, equivalent to 13.24% of the maximum electrical power that can be produced. However, the contribution of solar panels covers only 0.20% of the total electricity needs in the male dormitory building. Upon further analysis, the effectiveness of solar panels in meeting electricity needs, particularly for lighting in the building, is only 13.94%. Therefore, it can be concluded that the contribution of electrical energy generated by solar panels to the total and lighting needs in the male dormitory building is considered "ineffective."AbstrakPemanfaatan energi fosil secara terus menerus telah mengakibatkan dampak serius pada lingkungan dan bumi. Untuk mengurangi penggunaan energi fosil yang merugikan alam, UIN Raden Intan Lampung sebagai salah satu kampus ramah lingkungan di Indonesia berkomitmen untuk beralih ke energi terbarukan, khususnya melalui penggunaan panel surya dalam memproduksi energi listrik. Penelitian ini bertujuan untuk mengevaluasi sejauh mana efektivitas dan pemanfaatan panel surya di gedung asrama putra Ma’had Al-Jami’ah UIN Raden Intan Lampung dalam memenuhi kebutuhan listrik.Metode penelitian melibatkan observasi, wawancara, dan pengisian kuesioner sebagai upaya pengumpulan data. Hasil penelitian menunjukkan bahwa panel surya menghasilkan rata-rata 381,33 watt listrik setiap hari, yang setara dengan 13,24% dari daya listrik maksimum yang dapat dihasilkan. Meskipun demikian, kontribusi panel surya hanya mencakup 0,20% dari total kebutuhan listrik di gedung asrama putra. Ketika dianalisis lebih lanjut, efektivitas panel surya terhadap kebutuhan listrik khususnya untuk penerangan di gedung tersebut hanya sebesar 13,94%.Dengan demikian, dapat disimpulkan bahwa kontribusi energi listrik yang dihasilkan oleh panel surya terhadap kebutuhan total maupun penerangan di gedung asrama putra dinilai sebagai "tidak efektif."

Abstract

Male betta fish have high commercial value, making it more effective and profitable if only males are produced and reared. The aim of this study was to determine the effect of Tribulus terrestris fruit on the masculinization of betta fish (Betta splendens) using an immersion method. This research is quantitative. The population in this study consisted of the entire larval population of betta fish. A sample of 300 seven-day-old betta fish larvae was taken from this population and divided into 5 containers, each containing 20 larvae. The sampling technique used was Probability Sampling. Data collection was conducted with 5 treatments, each with 3 repetitions. The data obtained were tested using a One Way ANOVA or analysis of variance with a 95% confidence level. The results showed that the average data obtained from each treatment group differed significantly. The best dosage concentration in this study was treatment P2 with a concentration of 2 mg/L, resulting in the highest percentage of male betta fish at 84.49%.AbstrakIkan cupang jantan memiliki nilai komersial tinggi, sehingga akan lebih efektif dan menguntungkan bila hanya diproduksi dan dipelihara jenis jantan.

Abstract

Steamed cake is a type of cake that is enjoyed by all ages, both children and adults. This cake is usually made from wheat flour. Wheat flour causes dough to rise due to the gluten content. The use of excessive flour can be harmful to health. One alternative effort to replace wheat flour is to combine green bean sprout flour and Ambon banana peel flour. This study aims to determine the antioxidant level, the protein, fat, water, ash, and carbohydrate levels in steamed cakes made from green bean sprout flour and Ambon banana peel flour. This type of research is experimental. Antioxidants were analyzed using the DPPH method, protein was analyzed using the Kjeldahl method, and fat was analyzed using the Soxhlet method. The research results showed that the antioxidant activity in green bean sprout flour was 360.30 ppm which was classified as very weak, banana peel flour was 165.58 ppm which was classified as weak. The highest protein content was in sample T0 at 7.01%, the highest fat content was in sample T0 at 0.77%, the highest water content was in sample T2 at 43.95%, the highest ash content was in sample T3 at 1.15%, and the highest carbohydrate content was in sample T0 at 53.44%.

Abstract

Termites are sensitive to environmental fluctuations and hold potential as bioindicators of climate change. This study evaluated the survivability of Nasutitermes and Macrotermes under controlled variations in temperature, relative humidity (RH), and CO₂ concentration. Laboratory experiments were conducted using eleven temperature levels (0–50°C), seven RH levels (40–100%), and four CO₂ concentrations (500–2000 ppm). Each treatment was replicated three times with 50 worker termites per replicate. Survivability, measured as percent survival after one hour of exposure, was analyzed by one-way ANOVA followed by Tukey’s HSD test (p < 0.05). The results indicated that both genera exhibited sharp declines in survival under temperature extremes and elevated CO₂. Optimal survivability for Nasutitermes and Macrotermes occurred at moderate temperatures (25–35°C), relative humidity (60–80%), and ambient CO₂ levels (500 ppm), while extreme conditions significantly increased mortality. The study highlights species-specific tolerance thresholds and confirms that environmental stressors directly affect termite physiology and behavior. These results confirm termites’ potential as reliable bioindicators, providing a practical tool for monitoring ecosystem responses to climate stress and informing strategies for sustainable ecosystem management.
