This study investigates the optimization of ensiling time for fermenting Kepok/Saba banana peel into silage for ruminant nutrition. Two ensiling durations were compared: T1 with a 7-day ensiling time and T2 with a 14-day ensiling time. The results of the experiment reveal that while T2 demonstrated certain advantages, such as enhanced aroma and texture due to extended fermentation, the physical quality of silage from T1 was comparable, and the proximate analysis indicated no significant difference in nutritional content between T1 and T2. Additionally, T1 silage exhibited a lower crude fiber content compared to T2, suggesting potentially better digestibility and nutrient availability for livestock. These findings emphasize the practicality of choosing T1 to expedite production without compromising physical quality or nutritional integrity. The study underscores the potential of Kepok/Saba banana peel waste to be processed into silage, offering a sustainable solution for utilizing Lampung’s agricultural by-products for ruminant nutrition enhancement.

Dalam upaya mengurangi ketergantungan terhadap energi fosil, sel surya menjadi salah satu potensi energi terbarukan yang menjanjikan, terutama di wilayah dengan intensitas cahaya matahari yang tinggi seperti di Indonesia. Berbagai jenis sel surya telah banyak dikembangkan, mulai dari generasi pertama hingga generasi ketiga sebagai era baru dalam perkembangan teknologi sel surya. Concentrated Solar Cell (CSC) memunculkan harapan baru dalam pemanfaatan energi surya. Konsep dasar CSC melibatkan penggunaan lensa atau cermin konsentrator untuk meningkatkan intensitas cahaya matahari yang mencapai sel surya. Dengan memanfaatkan efek fotovoltaik pada material semikonduktor, CSC dapat meningkatkan efisiensi konversi energi matahari menjadi listrik. Mekanisme kerja CSC tidak hanya mengurangi jumlah sel yang diperlukan, tetapi juga memungkinkan desain multi-junction tandem yang lebih efisien, menggunakan bahan dan proses produksi yang umumnya mahal namun menjadi lebih terjangkau melalui penggunaan CSC. Berdasarkan ulasan analisis siklus hidup (LCA) yang dilakukan beberapa peneliti, CSC menunjukkan keunggulan dalam pengurangan material terbatas, seperti germanium (Ge) dan gallium (Ga), yang mendukung keberlanjutan pada skala besar. Keunggulan ini memberikan gambaran lebih luas tentang dampak positif CSC terhadap penurunan ketergantungan pada sumber daya yang langka dan peningkatan keberlanjutan di sektor energi.

The designation of COVID-19 as a global pandemic led to an increased use of single-use face masks, which result in waste that is difficult to degrade and has the potential to release microplastic fibers into the environment. This study aims to examine the im-pact of adding pineapple peel liquid waste (LCN) as a growth medium for the biodeg-radation of single-use face masks by bacterial isolates obtained from the waters of the Lampung Bay. The study investigates how LCN affects the efficiency of mask degra-dation by microorganisms, as well as how the ratio of LCN mixed with other growth media, such as Nutrient Broth (NB), influences the degradation process. The biodeg-radation process was carried out using a biostimulation technique, where bacterial iso-lates were incubated in media containing LCN at a 1:1 ratio. The degradation process lasted for 15 days, with the results being analyzed using gravimetry and Fourier-Transform Infrared Spectroscopy (FTIR). Gravimetric results showed a greater weight reduction in treated masks compared to the control masks. FTIR analysis also indicat-ed changes in the intensity of functional groups in the degraded layers of the masks, as well as the emergence of C≡C functional groups in the second and third layers. This study demonstrates that the addition of LCN can accelerate the biodegradation of sin-gle-use face masks, offering a new approach for managing mask waste.
