The experiment used a two-factor factorial randomized block design, namely: Application of NPK + Liquid Organic Fertilizer (POC) (b0 = 100% NPK without POC; b1 = 50% NPK + Bio-Extrem POC; b2 = 50% NPK + Organox POC) ; and Pruning (p0 = No Pruning, p1 = Pruning by maintaining 2 main branches). The results showed that pruning had a significant effect on the percentage of class C fruit quality, while fertilization treatment had no significant effect on all observed parameters. The interaction of the combination of fertilization and pruning had no significant effect on the growth and yield of melons, however, the combination of fertilizing with pruning was able to avoid fruit weight <1 kg (class C fruit quality). The use of a combination of 50% NPK + POC (Bioektrim / Organox) ferti...

Teknologi sel surya generasi ke-3 adalah Dye Sensitized Solar Cell (DSSC) yang dapat mengonversi sinar matahari menjadi listrik. Daun ungu merupakan daun yang tersebar di Indonesia yang juga merupakan daun yang ekonomis. Pada penelitian ini ekstrak pucuk daun ungu digunakan sebagai pewarna sensitizer yang diekstraksi dengan alkohol 96% dengan rasio campuran 20 gram pucuk daun ungu yang telah ditumbuk hingga halus dengan alkohol 50 ml, kemudian dilakukan perendaman dengan variasi perendaman 12, 24, dan 36 jam. Tujuan penelitian ini adalah untuk mengetahui pengaruh waktu perendaman terhadap tegangan yang dihasilkan oleh DSSC. Hasil arus tertinggi diperoleh pada variasi perendaman 36 jam sebesar 0,8 µA. Perendaman selama 12 jam sebesar 0,6 µA dan perendaman 24 jam sebesar 0,7 µA.
