Abstract

The study focuses on a drying system that integrates a rack-type convective dryer with a Peltier effect thermoelectric cooler to optimize the drying process of moringa leaves. This system is designed to achieve lower drying temperatures, which is essential for preserving the quality of the leaves. To evaluate the performance of this dryer, researchers use temperature and relative humidity data to construct a programmed psychrometric diagram. This diagram helps in calculating crucial parameters such as the absolute humidity and the specific volume of the drying air. These calculations are essential in determining the drying rate of moringa leaves. The results indicated that moringa leaves dried on drying rack-1 exhibited a higher drying rate compared to those on drying rack-2. Additionally, a drying air speed of 2.1 m/sec yielded a superior drying rate compared to a lower air speed of 1.5 m/sec. After 5.0 hours of drying, the Moringa leaves achieved a moisture content of 8.6% (wb) with a drying air speed of 2.1 m/sec, 9.3% (wb) with a speed of 2.6 m/sec, and 13.9% (wb) with a drying air speed of 1.5 m/sec. The drying process maintains a maximum temperature 59.3°C, placing it within the low-temperature drying category, which helps preserve the physicochemical quality of the dried Moringa leaves. Keywords: Dehumidification drying, Peltier effect thermoelectric cooling, Moringa leaves, Programmed Psychrometric Calculations.

Abstract

This study aims to optimize the biocomposites of sago pith waste (SPW) for sustainable packaging applications. The biocomposite was prepared using the biodegradable polymer polybutylene adipate-co-terephthalate (PBAT) as a matrix and methylendifenyl diisocyanate (MDI) as a chain extender. RSM-CCD was used to assess the impact of the incorporation of SPW (5-20% p/p) and MDI (1–5%) into the PBAT matrix on the tensile strength and elongation of biocomposites by melt mixing. The optimal formula shown by RSM was 5% SPW and 5% MDI, which resulted in a 5.14 MPa tensile strength and 8.14% elongation. The barrier properties of all treatments, including moisture content, contact angle, and water absorption, were checked. The optimal formula showed good barrier properties compared to other treatments: water content of 3.12%, contact angle of 42.84°, and water absorption of 0.82%. Other characterizations of SEM, FTIR, DSC, TGA, and biodegradability tests showed an increase in SPW-PBAT compatibility due to the use of MDI. MDI as a chain extender had a positive impact on the material's strength, and the addition of SPW accelerated the degradation process, thus improving biodegradability. Keywords: Biocomposite, Chain extender, Melt-mixing, Response Surface Methodology, Sago pith waste.

Abstract

Sweet corn production in Indonesia is relatively low due to instability and many factors, including infestation of pests and diseases, inappropriate and inefficient cultivation techniques, and the varieties. Pruning the leaves below the cob and applying nitrogen fertilizer may improve yield. The aim of this research was to investigate the combined effect of leaf pruning and types of nitrogen fertilizer on the growth and yield of sweet corn plants. A plot experiment was performed in a Randomized Block Design with 2 factors, namely leaf pruning (no pruning, 1 leaf remaining, 2 leaves remaining, and 3 leaves remaining below the cob), and types of N fertilizer (Urea 4.5 g/plant, ZA fertilizer 9.6 g/plant, and KNO3 fertilizer 15.5 g/plant). Results showed that the best type of N source was KNO3 fertilizer with fresh weight of dehusked cobs (217.68 g), cob diameter (44.84mm), and sugar content (16.26%). Combination treatment of KNO3 fertilizer and the 3 leaves remaining provided the best results on the parameters of fresh weight of husked cobs (308.50 g), cob length (18.83 cm), weight of husked cobs (10.12 kg/plot), and yield of husked cobs (28.11 ton/ha). Keywords: Cultivation, Fertilizer, Nitrogen, Productivity, Sweet corn.

Abstract

Durian seed is part of the durian fruit that has many benefits but are often considered useless. Durian seeds have the potential to be developed for its use because it contains high starch. This study analyzes the physical characteristics of durian seed starch from convection oven drying. This study used a completely randomized design with two factorials: deposition time (24 and 48 h) and drying temperature (60, 70, and 80℃). Durian seed starch was processed by drying and crushing, then sieved with 100 mesh size. The data analysis used was a two-way ANOVA test followed by Duncan's. The results of ANOVA analysis of different drying temperatures affect the value of water content, yellowness (b), grain average (D), water absorption (DSA), and yield. At the same time, the length of deposition in the process of making starch affects the value of yield variables. The results of durian seed starch characterization resulted in the highest moisture content value of 6.26%; brightness value of 92.92; reddish value of 2.06; yellowish value of 2.24; water absorption value of 1.28 ml/g; and yield value of b16.03%. Keywords: Convection oven, Drying, Durian seed, Starch.

Abstract

Water quality is a key indicator related to the sustainability of living things in a watershed. However, human activities have led to a decline in the water quality caused by industrial, domestic and agricultural waste. This study aims to predict the pattern of TDS parameters at unsampled points through a geostatistical approach, namely Kriging. Experimental measuements were conducted in the Bedadung River, Jember Regency, especially in a segment of Patrang to Wuluhan sub-districts. Currently, the river is classified as Class 3, which is below the standard, one of the water quality parameters is TDS (Total Dissolved Solid). The TDS estimation results were obtained in the range of 48.26 mg/L - 175.52 mg/L. The predicted value of TDS using the kriging method at unsampled points resulted in an RRMSE value of 8.40 %. This study revealed that the water quality of Bedadung River from Patrang to Wuluhan sub-districts was still below Class 2 standards, emphasizing the need for continuous monitoring and improvement efforts. Keywords: Ordinary kriging, River water quality, Semivariogram, Total dissolved solid.

Abstract

Cassava is a commodity that has not been widely innovated on. Mocaf flour and gaplek flour can be innovated as snacks using extrusion technology. This study examined the effects of varying ratios of mocaf/gaplek flour to corn grits (0% / 10% / 20%), initial moisture content (14 / 16 / 18%), and barrel temperature (120 / 130 /140°C) on the physical properties of the extrudate and to characterize the physical properties of the extrudate using PCA analysis. Physical properties such as expansion ratio, particle density, moisture content, color (L and b*), water absorption index (WAI), water solubility index (WSI), and hardness were analyzed. The extrusion process was performed using a SYSLG-IV twin screw extruder (10 15 kg/hour capacity). The addition of mocaf/gaplek flour increased particle density, moisture content, L, and hardness but decreased the expansion ratio. Initial moisture content had a negative effect on the expansion ratio, WAI, and WSI while having positive effect on particle density, moisture content, and hardness. Increasing barrel temperature decreases the expansion ratio and moisture content but increases WAI and WSI. Extrudate treated with 14% moisture content was found to have better physical properties. Keywords: Corn grit, Extrusion, Gaplek flour, Mocaf flour, Physical properties.
