Abstract

Banana is tropical fruit contain health nutrition and fiber. Dwarf banana is one of type banana that well growth in Indonesia, particularly in Lampung Province. However, its economic value become exported commodities is limited by its short shelf life. In this study, the physicochemical changes were observed under vacuum packaging storage, in order to know the potency of vacuum packaging to prolong the shelf life of dwarf banana. The results showed that the vacuum packaging could reduce weight loss compare to other treatments. The maintenance of green color by vacuum packaging was also showed positive result. Furthermore, the dwarf banana under vacuum packaging storage was also showed lowest TSS, in other words, the dwarf maturity could be delayed. These results suggested the vacuum packaging could be used as potential packaging for dwarf banana Keywords: dwarf banana, vacuum packaging, postharvest, physicochemical properties

Abstract

Tomatoes have a short storage time and are easily damaged. Tomatoes have thin skin and high water content, so the commodity will quickly deteriorate after being treated with simulated transportation and storage processes. This research aims to analyze the effect of the simulation time on weight loss, mechanical damage, color, hardness, and total soluble solids of tomatoes and to explain the effect of simulation time treatment on weight loss, mechanical, damage, color, hardness, and total soluble solids of tomatoes during storage. This study used a completely randomized design using transportation simulation vibration times (30 minutes and 90 minutes) and controls not given vibration treatment using three repetitions and kept for 8 days. This research shows that the treatment of variations in vibration time affects mechanical damage and weight loss. Vibration time of 30 minutes on day 8 I had mechanical damage of 15,38%, weight loss of 5,77%, color L* 40,88, color a* 20,06, hardness 11,88, and total dissolved solids 4,25. Vibration time of 90 minutes has mechanical damage of 20,51%, weight loss of 7,53%, color L* 40,63, color a* 21,21, hardness 11,65 and total dissolved solids 4,33.

Abstract

Palm Oil Mill Effluent (POME) is a promising substrate for biohydrogen production through dark fermentation, although pretreatment is often required to enhance hydrogenogenic activity. This study evaluated the effects of alkaline (NaOH) and thermal pretreatments on POME characteristics and hydrogen production. Fresh POME was sieved and adjusted to initial pH values of 6, 7, or 8 using 6 M NaOH, with or without heat shock treatment (100 °C for 60 min). Batch fermentation was conducted at 60 °C for 24 h, while pH, oxidation-reduction potential (ORP), and dissolved oxygen (DO) were monitored. Pretreatment shifted POME conditions from acidic and oxidative to neutral-alkaline and reductive environments, with several treatments achieving ORP values below −200 mV, indicating favorable anaerobic conditions. Refrigerated storage reduced pH and increased ORP, whereas NaOH addition increased pH and lowered ORP. Hydrogen production varied among treatments. The highest yield was obtained from fresh POME adjusted to pH 7, producing 0.03655 g H₂ with an ORP of approximately −514 mV. In contrast, stored POME subjected to pH 7 adjustment and heat shock produced substantially lower hydrogen yields. In a second batch, pH 8 treatments generated 0.01157–0.02002 g H₂, representing 2.4–3.1 times higher production than the controls, while pH 6 treatments showed the lowest yields. Overall, neutral-to-alkaline pH and strongly negative ORP were associated with improved biohydrogen production.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini merupakan implementasi Tri Dharma Perguruan Tinggi yang bertujuan memberikan solusi terhadap permasalahan limbah jerami pascapanen di Desa Sabah Balau. Melalui metode learning by doing, para petani dilibatkan secara langsung dalam proses pengolahan limbah jerami menjadi produk bernilai guna. Kegiatan ini mencakup pembuatan Mikroorganisme Lokal (MOL) dari bonggol pisang sebagai bioaktivator alami pengganti EM-4 yang juga berfungsi sebagai pupuk cair dan pestisida nabati, serta pelatihan pembuatan pelet pakan ternak berbahan dasar jerami sebagai upaya ekonomis untuk menekan biaya pakan dan mengurangi pencemaran lingkungan. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan petani dalam pengelolaan limbah pertanian, reaktivasi Rumah Produksi Kelompok Tani Karya Makmur, serta penguatan kemandirian dan keberlanjutan kelompok tani dalam menerapkan praktik pertanian yang ramah lingkungan dan berkelanjutan.
