Abstract

To study the effect of drying on white pepper seeds, a thorough knowledge of the drying kinetics is required. The drying kinetics of a material can be explained using a mathematical model which is usually used to estimate the drying time of the material. This study aims to determine the appropriate drying mathematical model for drying white pepper spouted beds with microwave preheating treatment. The equipment used in this study was a spouted bed dryer designed for laboratory scale. The material used in this study was wet white pepper seeds obtained from smallholder plantations in Enrekang district, South Sulawesi province with an age of approximately 8-9 months after flowering. The white pepper was directly put into the spouted bed drying room for non-preheating treatment, while for the preheating treatment the pepper was stored in a container then put in a microwave oven for 2 minutes. During the drying process, several parameters for drying analysis are measured. There are seven different mathematical drying models evaluated. In determining the most appropriate mathematical model, model validation is required through statistical methods. The statistical methods used were correlation analysis, reduced chi-square (χ2) test, and root means square error (RMSE) analysis. Based on the analysis, the Weibull model fulfills the criteria to be the best model with the correlation coefficient r (0.99990) being the highest and the χ2 (0.00001) and RMSE (0.00385) values ​​being the lowest. Thus, the Weibull model can be used to predict drying time and moisture content.

Abstract

Direct seed planting tools or commonly abbreviated as ATABELA have been commonly used in rice cultivation in Indonesia. One of the problems that often occur in the use of this tool is the inconsistency in the number of seeds released. Besides, the seeds that are issued are usually more than three seeds, so that it can cause competition in the growth process. Therefore, it is necessary to develop direct seed planting tools with precise seed dosage. This study aims to design an applicator for planting rice seeds directly by dropping the seeds using vacuum pressure. Another goal is to know the pressure that can be generated as well as the forward speed required to produce the desired vacuum pressure. The first step in this research is to identify the pressure needed to move the seeds, then design a tool based on the pressure data. The test is carried out using a DC motor as a substitute for wheel rotation to determine the forward speed required to obtain the required pressure. The moisture content of the seeds used is 22.71% and the required pressure is 97 kPa (4 kPa under standard atmospheric pressure), the required forward speed is 2.5 m / s, so it is necessary to modify the ratio of the wheel pulley to the drive shaft.

Abstract

Microgreen is a functional food crop that aims to create a globally sustainable food diversification with high nutritional value compared to ordinary plants. Basil is one type of plant that is often used as a microgreen because of it is complete nutritional content. Increasing the production and quality of microgreens can be done by providing LED lighting with the required light spectrum and increasing the duration of irradiation. The aim of this study was to examine the growth and biochemical response of microgreens bacilli to the combination of red, blue, and red:blue LEDs and the duration of irradiation for 12, 16 and 20 hours. The research was carried out on April 2021 - May 2021 at the Plant Ecology and Production Laboratory and the analysis of chlorophyll, carotenoids and phenols was carried out at the Laboratory of Physiology and Plant Breeding, Faculty of Animal and Agricultural Sciences (FPP), Diponegoro University. The experimental design used in this study was a completely randomized design (CRD) with a factorial pattern of 5 x 3 with 3 replications, so there were 45 experimental units. The first factor was the LED color combination which includes L1: 100% Red: 0% Blue, L2: 0% Red: 100% Blue, L3: 70% Red:30% Blue, L4: 50% Red: 50% Blue, L5: 30 %Red:70%Blue. The second factor was the length of irradiation including T1 (12 hours), T2 (16 hours), T3 (20 hours). Based on the research conducted, it can be concluded that there was an interaction between the combination of light color and the duration of irradiation on the biochemical content of microgreen basil. Radiation with a combination of 100% red light with irradiation for 20 hours increased the chlorophyll and carotenoid content of basil microgreen.

Abstract

Preservation is one way to prevent the deterioration of fish quality. This study aims to utilize pedada leaf extract (Sonneratia caseolaris) as a natural preservative in fresh mackerel. This research was divided into three stages, namely sample preparation, pedada leaf extraction and extract application to fish. This study used a completely randomized factorial design consisting of three factors. The first factor was the addition of pedada leaf extract. The second factor is the storage temperature of fish, namely room temperature (23º-27ºC), cold temperature (10ºC), freezing temperature (0ºC). The third factor is storage time, namely 1, 7 and 14 days. Each treatment was repeated twice. Parameters tested include pH value, water content, protein content, total plate number (ALT) and E-coli. The results showed that the addition of pedada leaf extract, differences in storage temperature, and storage time had a significant effect (sig <0.05) on the pH value, water content, protein content and total plate number (ALT). Furthermore, the results of the E-coli test showed that the treatment of cold temperature and freezing temperature on fish with the addition of pedada leaf extract showed negative E-coli content.

Abstract

The Cikeruh sub-watershed is an area with a high population growth rate, which causes land conversion to occur in several sub-districts hence has implications for decreasing water availability and increasing water demand in the Cikeruh sub-watershed. This study aims to determine the status of water carrying capacity in the Cikeruh sub-watershed by comparing the ratio between water demand and availability. Water demand is calculated using the standard determined by SNI 19-66728.1, 2002; SNI 67281-2015; and the Directorate General of Human Settlements of the Public Works Service in 1996, while the sectors calculated are domestic, non-domestic, industrial, agriculture, animal husbandry, and fisheries. Water availability is calculated by estimating the volume of flow that occurs in the Cikeruh sub-watershed using the Soil Conservation Service Curve Number (SCS-CN) method from USDA involving hydrological data from 2011 to 2020. The result showed that the water availability in the Cikeruh sub-watershed in 2020 was 350,962,957.9 m3/year, while the water demand in the Cikeruh sub-watershed changes dynamically every year. The water demand in the Cikeruh sub-watershed in 2011 was 588,925,151 m3/year. In 2015, it was 754,796,534 m3/year, while in 2020 was 571,509,488 m3/year. The calculation results showed a water deficit in the Cikeruh sub-watershed, where the value of water demand is higher than the water availability, the ratio is 0.641, which means that the environmental carrying capacity has exceeded (overshoot) because the ratio value is < 1.

Abstract

Moringa (Moringa oleifera) has been known for centuries as a multipurpose plant, nutrient dense and efficacious as medicine. However, the manufacture of Moringa into flour or powder and its development into additional functional food has not been done much. One effort that can be done is to make flour from Moringa leaves as an addition to nutrient-rich functional foods. The main content of this Moringa leaf turns out to be higher if the Moringa leaves are processed first into a dry or flour form. This study aims to determine the best drying temperature and drying time used in the process of making Moringa leaf powder based on chemical analysis, vitamin C and moisture content and to determine the organoleptic properties of Moringa leaf powder based on different temperatures and drying times. The research method used is to determine the best drying temperature and drying time using drying temperatures (35 oC, 50 oC, and 65 oC). Drying time (5 hours, 6 hours and 7 hours). The best drying temperature and time will be determined by testing the chemical analysis of Moringa leaf flour, vitamin C and moisture content tests and organoleptic tests, (hedonic method). The results of the research on the best Moringa leaf powder formulation based on the analysis of vitamin C and moisture content were the treatment with a drying temperature of 35 oC and a drying time of 5 hours. The most preferred organoleptic properties in the form of texture, taste and aroma are the treatment at a drying temperature of 65 oC and a drying time of 7 hours, while the most preferred color is at a treatment of 35 oC and a drying time of 5 hours.
