Abstract

The purpose of this study was to find out how effective citric acid is against the nonenzymaticprocess of browning Yali Pear fruit juice (Pyrus bretschneideri Rehd. Theresearch was conducted in a complete randomized design consisting of 5 replications. Thenon-enzymatic browning inhibition process was tested with citric acid treatment as the mainfactor with five concentrations ie 0% w/v, 2,5% w/v, 5% w/v, 7,5% w/v and 10% w/v.Qualitative parameters were dehydrogenase enzyme activity and reducing sugar level.Quantitative parameters were browning index and total soluble carbohydrate content.Levene test, analysis of variance, and Tukey test were performed at 5% significant level. Theresults showed that decrease in dehydrogenase enzyme activity occurs along with increasingthe concentration of citric acid. The level of reducing sugar has increased along with theincrease of citric acid concentration. The 7,5% w/v citric acid concentration effectivelyinhibited non-enzymatic browning of Yali Pear juice with a 21% reduction in the browningindex. Total soluble carbohydrate content increased 7% at 7.5% w/v citric acidconcentration. From the results of the study it was concluded that citric acid at 7,5% w / vconcentration was the inhibitor of non-enzymatic browning and dehydrogenase enzymeactivity, but stimulator of total soluble carbohydrate and reducing sugar level.

Abstract

Use of synthetic fertilizers bring environmental pollution, increase weed growth, reduceatmospheric oxygen levels, decrease the fertility of agricultural land, causing eutrophicationand run-offs, also even damaging coral reefs. Recent biotechnology approaches can beutilized to create a new variety of self-fertilization plants that allows it to supply its ownnitrogen making it possible to overcome nitrogen problems and avoid them. This reviewaims to understand how far genetic engineering approach can be used by the introduction ofnif regulon from Klebsiella penumoniae. The nitrogenase-encoding genes which make up thenif regulon proved can be inserted into the mitochondrial genome as like Allen et al. (2017)did in their research. The western blotting result showed that the research succesfullyintegrated the nif regulon to the genome and expressed their proteins.

Abstract

Hydroponic cultivation is an alternative choice for people who plant various types of plants that can be consumed by themselves every day. In addition, hydroponics is one way to grow crops on a large scale without requiring land that is very suitable for cultivation in urban areas. However, this system has several drawbacks, namely, hydroponics really requires a controlled environment, such as monitoring the degree of water acidity, water temperature, and water nutrient density. It needs to be monitored and controlled to avoid a decrease in plant quality. Several ways can be done by using manual measuring tools which actually take time if the hydroponic system is on a large scale, the alternative is to use an Android-based control and monitoring system. This study aims to examine the effect of the best AB Mix nutrient concentration on the growth and production of Sawi Pagoda with the NFT hydroponic system and to control pH, temperature, humidity and nutrients automatically using the Ardiuno Uno sensor. This research was conducted at Rootop PS. Plantation Cultivation from August to October 2020. The design used was a completely randomized design consisting of one factor, namely the concentration of AB mix nutrients consisting of 2 levels: A1: 1000 ppm: 1200 ppm: 1400 ppm (given according to the age of the plant per / week) and A2: 1100 ppm: 1300 ppm: 1500 ppm (given according to plant age per / week). The research was repeated as many as 20 replications so that there were 40 experimental units. The results showed that the A1 treatment level with the concentration of AB Mix nutrient solution (1000 ppm: 1200 ppm: 1400 ppm) was the best treatment level for the increase in plant height and number of leaves on the 2nd and 3rd week and the final plant weight. The hydroponic Nutrient Film Technique system can be monitored and controlled automatically by Arduino, making it easier to control temperature, humidity, ppm of nutrients, and nutrient pH.

Abstract

At corn post-harvest handling activities, the shelling process is an important activity that needs special attention. One of the mechanical equipment for post-harvest handling of corn is the corn sheller. The purpose of this study was to measure the scattered losses and quality losses in the corn threshing / shelling process and to analyze the performance of the corn thresher / sheller machine. The results showed that the use of corn sheller with a rotating speed of 652 rpm with a tool capacity of 1.08 tonnes / hour resulted in practical scattered losses (TP) was 0.69%, scattered losses 1 (T1) was 1.85%, scattered losses 2 (T2) was 0.21%. and the scattered losses 3 (T3) was 1.46%. From the results of manual bleaching of shelled corn kernels according to the SNI 01-3920-1995 quality criteria regarding the quality of shelled corn (provided that the corn kernels are dried again until the moisture content reaches 14%), while the results of mechanically plucked corn kernels are not suitable with SNI 01-3920-1995 regarding the quality of shelled corn because it has a level of damage to the seeds> 8% due to the high moisture content of the corn kernels.
