Abstract
Orange is a fruit that is easily subjected to physical, chemical and biological changes during storage. The change in behavior was due to the absence of handling of the fruit after harvest. To maintain the quality of the fruit and to extend the shelf life, the fruit was manipulated by waxing and packaging. The research objective was to determine the effect of waxing and proper packaging methods on the quality of Pontianak Tangerine fruit during storage 10 days after harvest. The research was conducted at the Post Harvest Laboratory of East Java AIAT in January 2018. The research design was arranged completely randomly with 2 treatment factors. The factors are wax dyeing (waxing and without waxing) and packaging methods (plastic baskets, black plastic bags, white plastic bags, transparent plastic, cardboard and fruit nets). The experiment was repeated 3 times per unit experiment / replication using 10 pieces. The results showed that on the second day after harvest there was a significant difference between the wax and the packaging method on fruit volume, fruit skin brightness color and fruit juice brightness color. Meanwhile, the waxing factor and packaging method were not different with respect to sugar content, acid content, fruit weight, juice volume, and fruit juice color. For yellowish skin color, the packaging method is different but there is no difference in waxing, the packaging method with a white plastic bag is yellow. Observations on day 10 after harvesting wax did not affect fruit volume, fruit skin color, attack by plant-disturbing organisms, juice color, sugar content, acid and vitamin C levels, but had an effect on fruit weight, skin brightness, juice volume, juice brightness and juice yellowish color. The method of packaging affects the volume of fruit, volume of juice, yellowish juice color and vitamins. C

Abstract
Willingness to pay (WTP) has been widely used to measure the value of an item, both private and public goods, also shared resources. More recently, the WTP concept is also applied to marketing management for product development and pricing strategies. Ketakasi ground coffee is a premium Robusta coffee product of Jember Regency. The price of Ketakasi ground coffee per package with a net weight of 160 grams was sold at IDR 15,000, relatively more expensive compared to the price of branded ground coffee product which were sold at an average of IDR 12,000 per pack. Perception about the price of Ketakasi ground coffee which was considered expensive by consumers could make an obstacle for producers to achieve the expected target customers. This research aimed to determine the value of WTP of Ketakasi ground coffee; and factors influencing the WTP. A total of 60 respondents were interviewed in this research. Average value of consumers’ willingness to pay was analyzed by the descriptive statistics, while the factors influencing the willingness to pay consumers were analyzed by logistic regressions. Results showed that the value of consumers’ WTP reached IDR 16,000 per pack. This value was actually higher compared to the current market price, i.e., IDR 15,000, with consumer surplus of IDR 1,000. The taste of local coffee was identified as the main reason why consumers willing to pay higher than the current market price. Factors significantly influencing consumers’ WTP of Ketakasi ground coffee were consumer’s gender, types of jobs, and income.

Published: May 2021

Abstract
The tobacco plant (Nicotiana tobaccum L) is one of the most valuable crops in Jember, Indonesia. One of the destructive diseases of tobacco is bacterial wilt disease caused by Ralstonia solanacearum. Plant resistance inducer (PRI) agents such as Pseudomonas fluorescens, flagella, and salicylic acid are known to have the potency to control plant pathogens by inducing a mechanism of resistance in the plant. However, there is still no study comparing their effectiveness in controlling bacterial wilt disease. This research aimed to study the effectiveness of each PRI in controlling tobacco bacterial wilt disease. The molecular assay using Polymerase Chain Reaction (PCR) confirmed that FTb4 bacteria is R. solanacearum and used either as inoculum or as a PRI flagella source. In addition, P. fluorescens IC1 was isolated from a pepper plant rhizosphere in Jember. PRIs (Isolate IC1, FTb4 flagella, and salicylic acid) were applied to control bacterial wilt disease. In vivo results showed that treatment of PRIs with medium-resistant criteria at 7 days before pathogen inoculation successfully suppressed disease incidence up to 90-93 % and disease severity up to 33.33 %. Usage of PRIs on tobacco plants increased peroxidase activity and total phenol production, indicating that PRIs induced plant resistance.

Abstract
In order to study the effect of swirl distortion on the performance and stability of the compressor, this paper optimizes the design of the existing swirl distortion generator, and designs three different structures of pair swirl distortion generator. Using CFD technology, a comparative analysis of the standard pair swirl distortion flow fields and the pair swirl distortion flow fields produced by three newly designed swirl distortion generators and the existing pair swirl distortion generator is performed. The results show that the optimally designed distortion generator reproduces the standard pair swirl distortion flow field to a higher degree than existing distortion generators. On the three measurement rings, the average swirl angle error is reduced by 5.35%, 19.88%, and 8.22%. The total pressure recovery coefficient is increased by 2.2%, which proves that the design method in this paper is more reasonable and achieves the purpose of optimal design.

Abstract
In the present work, Zn-HA composites were developed by powder metallurgy route targeted for bone implant applicaitons. Zn-HA powders with varying HA content (1, 2, and 4 wt.%) were ball milled for 1 hr and sintered to produce composite compacts. X-ray diffraction (XRD) studies were done for all the ball milled powders and sintered compacts. No impurities were observed in the ball milled powders. Microstructural observations revealed the formation of lamellar structure in the composites due to the plastic deformation of the Zn powders during ball milling. Grain size measurements revealed the decreased grain size with increase of addition of HA. Furthermore, aspect ratio (length to thickness ratio) of the grains was measured and found that the aspect ratio was also decreased with the increased HA content. Higher microhardness was measured for all the composites compared with pure Zn. However, composite with 1% has shown higher hardness compared with the remaining composites. Form the preliminary observations, it can be concluded that Zn-HA composites can be successfully produced with lamellar morphology by ball milling followed by sintering for biomedical applications with increased hardness.
