Abstract

This research aimed to determine the effect of ethanol vapor and storage temperature on quality and shelf life of broccolies. The research used completely randomized design (CRD) with two factors of treatments. The first factor was ethanol vapor treatment with 4 levels of consentrations; 0%, 10%, 20% and 30%. The second factor was the storage temperature, consisting of 2 levels; room temperature (26?) and low temperature 2?. The florets of broccoli as controls were prepared without treatment of ethanol vapor and placed at room temperature and low temperature. The measured parameters were: respiration rate, hardness, color and sensory evaluation includes flavor, color, smell, freshness, and crispness. The data were satistically analysed using analysis of variance. The significant result of the analysis was folowed by the test of Least Significant Difference (LSD 5%). The results showed that ethanol vapor concentration 10% was the best treatment since it could effectively maintain the level of greenness of broccoli by up to the day 5 with a value of -6,23 compared to controls. Ethanol vapor treatment and storage temperatur had no significant effect on the hardness level of the florets on stalk of broccoli. The rate of respiration was affected by storages temperature. At the room temperature, the comsumption of O2 increased until day 5 about 102,2 to 193,17 ml O2/kg.hr while at low temperature, the O2 consumption was lower until day 15 were approximately 65,4 to 60,4 ml O2/kg.hour. Sensory evaluation showed that the broccoli was maintain quality by up to day 4 at room temperature, while in cold storage can extended the shelf life by up to 8 day.

Abstract

Pig feed is an important component in pig farming activities. This research aims to determine the characteristics of heat transfer in the steaming process for raw materials used in pig feed in Antiga Kelod Village, Manggis District, Karangasem Regency, Bali. The study used a group randomized design (RAK) method. The first factor was the height of the partition (P), with three variations of 14 cm, 16 cm, and 18 cm, while the second factor was the type of material (M), consisting of banana tree trunks, cassava, and kolbanda. Steaming was carried out for approximately 90 minutes for each mass of 1.5 kg. The results showed that banana stems at a bulkhead height of 14 cm (M1P1) had an airflow velocity of 0.52 m H₂O, a calorific value of 10,325.00 J, a texture value of 13.57 N, and a moisture content of 83.86%. Cassava material at the same height (M2P1) had an airflow velocity of 0.54 m H₂O, a calorific value of 10,896.80 J, a texture value of 7.61 N, and a moisture content of 51.90%. Kolbanda at 14 cm (M3P1) had an airflow velocity of 0.52 m H₂O, a calorific value of 10,325.00 J, a texture value of 5.56 N, and a moisture content of 54.80%. The data indicate that evaporation occurs during the steaming process, and decomposition in the feed ingredients softens the texture, making the feed easier to consume.

Abstract

Coffee is a plantation product that serves as a major source of foreign exchange for the country. Robusta coffee is a production base in several regions in Indonesia, including Bali, where the largest production occurs in Pupuan District, Tabanan Regency. Despite the high production volume, Robusta coffee in Pupuan District is still mostly processed using traditional equipment, maintained due to the high investment cost of modern post-harvest facilities. This study aims to determine the appropriate criteria and sub-criteria for prioritizing robusta coffee postharvest facilities and to identify the priority facilities that can reduce quantity losses. The study uses a purposive sampling method to select potential respondents and employs the Analytical Hierarchy Process (AHP) for analysis. The results indicate that the huller is the priority tool in postharvest handling of Robusta coffee and can effectively reduce quantity loss.

Abstract

Plasma technology has been recently developed due to its unique properties and potential applications across various fields. Plasma is a gas whose constituent molecules are dissociated and exhibit reactive properties. However, because of these properties, plasma must be used immediately after generation. Activating water with plasma makes the water more reactive, allowing it to be utilized similarly to plasma in gas form. This literature review presents water activation technology using plasma, focusing on the generation mechanism and the accompanying reactions. The article also introduces plasma technology, which is currently minimally studied in Indonesia.

Abstract

Microgreens are vegetables harvested at a young age from vegetable seeds, with radish microgreens providing higher nutritional value compared to mature plants. Pre-sowing treatment and nutrient provision are factors that influence microgreen productivity. This study aimed to determine the effect of pre-sowing treatment and fertigation interval on productivity and identify the treatment that produced the best results. A randomized block design with two factors pre-sowing treatment and fertigation interval was used with three replications. The pre-sowing treatments consisted of soaking and not soaking, while the fertigation intervals were without fertigation, every day, every 2 days, and every 3 days. Observed parameters included fresh weight, dry weight, plant height, and leaf SPAD values. Results showed significant effects on fresh and dry weight (P<0.05), while plant height and leaf SPAD values were not significantly affected (P>0.05). Soaking before sowing combined with daily fertigation produced the highest productivity, with 0.14 g/cm², 108.70 g fresh weight, 9.70 g dry weight, 9.49 cm plant height, and a leaf SPAD value of 45.99. This treatment was concluded to be the most effective for maximizing radish microgreen productivity.
