Published: October 2020

Abstract

Bacillus subtilis ATCC 21556 produces the highest an antifungal of iturin A compared to the other three of B. subtilis strains ATCC 15841, ATCC 27505, and ATCC 21770. An Iturin A has a wide antifungal spectrum activity, therefore making it an ideal potential for controlling of the fungal diseases of crop not only for preharvest but also for postharvest control. This research work if very useful to overcome the problem of decreased post-harvest production of chili and tomato that caused by the fungal pathogen. Many of the fungi cause of postharvest disease in various fruits and vegetables. Biological control of postharvest diseases has emerged as an effective alternative control since the impact of chemical control of post-harvest disease cause serious consequences for human health and the environment. Twenty microliters of B. subtilis ATCC 21556 (approximately 1 x 107 cell mL-1) were injected into the fruit of red chillies and tomatoes to control its postharvest diseases caused by fungal of Colletotrichum scovillei 244830. The lesion diameter of C. scovillei 244830 significantly (p<0.005) reduced about 52-64% in chili and 39-44% in tomato. An invitro test showed that percent growth inhibition of B. subtilis ATCC 21556 against C. scovillei 244830 was about 52.38% at 14 days of the incubation time. For successful infection of the fungal pathogens into the host plants, they produce the extracellular enzymes. Qualitative test of the extracellular enzymes showed that C. scovillei 244830 produced the enzymes of amylase, laccase, lipase, pectate lyase, and protease and it did not produce polygalacturonase.

Abstract
Probiotics are living organisms with many beneficial effects on the health of host if consumed in sufficient quantities. These beneficial effects have been initiating efforts directed towards exploring strains Lactic Acid Bacteria (LAB) as probiotic from fermented food such tempe and tape. Although several groups of microorganism from fermented foods such as tempe and tape were reported, the potential LAB derived from those food sources is limited. The aim of this study was to assess probiotic candidate from LAB strains isolated from tempe and tape based on in vitro analysis. A total of 30 LAB isolates were tested for probiotic properties including tolerance to bile salt and acid, antimicrobial activity, simulated gastric juice (SGJ) and simulated intestinal juice (SIJ), physiology and enzymatic properties. The results showed eight bacterial isolates (Pediococcus pentosaceus Su-ls13, P. pentosaceus Su-ls14, Enterococcus faecalis Su-ls15, P. pentosaceus Su-ls16, P. pentosaceus Su-ls21, P. pentosaceus Su-ls22, P. pentosaceus Su-ls24 and Lactobacillus plantarum Su-ls29) fulfilled the criteria as probiotic candidates, including the capability of producing antimicrobial activity by inhibiting the growth of 12 pathogenic bacteria, have survivability under the condition of (or high tolerance to) low pH, and being exposed to bile salt, simulated gastric juice and simulated intestinal juice. All isolates were able to grow at NaCl 3-6.5%, 30-45°C and produce phytase. In addition, six isolates (Su-ls13, Su-ls14, Su-ls15, Su-ls16, Su-ls21, Su-ls22) were able to produce protease and two isolates (Su-ls22, Su-ls24) were able to produce amylase.

Published: October 2020

Abstract
Thermal images of Landsat satellite can be utilized by estimating the land surface temperature. Moreover, retrieving the temperature estimation before the current event can be done using temporal analysis. Land surface temperature estimation requires Land Surface Emissivity (LSE) value through the Normalized Difference Vegetation Index (NDVI) approach. The result showed that the average land surface temperature in West Aceh District in 2013 was 26.07 °C. The result also showed that the spatial distribution of temperature spread accordingly following the transect pattern. The temperature in the coastal areas was higher than the hinterland. This phenomenon is due to high built-up in the coastal regions, whereby vegetation is dominant in the hinterland areas.

Authors: Avia L Q 
Published: October 2020

Abstract
The tropical cyclones (TCs) are a serious danger to marine and coastal areas in the tropics because they cause strong winds and extreme sea wave height. The combination of these two parameters will be dangerous for shipping safety. The purpose of this study was to investigate the effect of Tropical cyclone on significant wave heights and surface winds in the southern sea of Java with case studies of TC Cempaka (21-29 November 2017) and TC Dahlia (26 November-4 December 2017). The relationship between two parameters was also discussed in this paper. Both of these tropical cyclone events are interesting to study because they occured in the southern sea of Java and in adjacent time periods. Special attention was paid to the southern sea of Java because it had high shipping traffic where 8 locations were used as case studies. Significant wave height and wind conditions were evaluated using data obtained from the European Mid-Term Weather Forecast Center (ECMWF) with 6 hourly temporal resolution (time UTC 00.00, 06.00, 12.00, 18.00) and 0.5 x 0.5 degrees spatial resolution. The obtained results showed that the influence of TC Dahlia on significant wave height and surface wind appears stronger than the influence of TC Cempaka. During TC Dahlia, the strongest relationship between wind and significant wave height was in the southern sea of Central Java 01 and Yogyakarta 01 with correlation coefficients of 0.84 and 0.81, respectively. While the frequency of extreme wave height of 55.56% appeared to occur in the southern seas of West Java 01 and Central Java 01.

Abstract
A selective sensor based on carbon paste electrode with ferrocene (Fc/CPE) has been investigated. The Fc/CPE was prepared for selective dopamine (DA) in presence of interference compounds as ascorbic acid (AA) and uric acid (UA). The Fc/CPE can well resolve the peak oxidation of DA, AA and UA. The modified electrode exhibited better electrocatalytic activity and catalytic efficiency 3.5 times higher than using the unmodified electrode. The electrochemical behaviours of DA at the surface of the modified electrode were studied by cyclic voltammetry (CV). Using differential sweep voltammetry (DPV) at the optimum condition the determination of DA was measured in the concentration range of 0.5 μत -10 μत with a detection limit of 0.2437 μM and a correlation coefficient of 0.9995. The Fc/CPE has been applied to determination of DA spike into simulated sample and showed good recovery.

Abstract
Connecting rod is a vital part of an internal combustion engine which forms a link between piston and the crankshaft. Due to huge amount of forces acting on the piston owing to high engine load and rpm, cyclic compressive and tensile forces act on the connecting rod and results in fatigue and failure. So, to in order avoid this, the existing connecting rod is to be replaced by composite materials. Because these materials have good mechanical properties such as wear resistance, hardness and high tensile strength. A 3D model of connecting rod is modeled using Solidworks and FEA analysis is carried out by ANSYS 18.2. In this paper analysis is performed on the connecting rod using AL7075, AL6061, AL7075+10%SiC and AL6061+10%SiC to find out the best material for construction of connecting rod.

Published: October 2020

Abstract
The present work is aimed to investigate the effect of mixed vegetable oils in surface quality during surface grinding of Inconel 625 by vitrified bonded alumina grinding wheel. Three different blends of vegetable oils were considered for the study in which castor oil was base oil and blending oils were soya bean oil, corn oil and rice bran oil. Castor oil has good lubricating properties but its high viscous and poor rheological properties make it directly unviable for lubrication applications. In this study, the rheological properties of the castor oil were modified to cater to the specified needs for grinding of Inconel 625 by mixing it with some other vegetable oils. The blends were prepared in 1:1 proportion. Experiments were conducted using the blends of vegetable oils in grinding of Inconel 625 under identical work conditions. The finished work piece was measured for its surface quality with respect to its average surface roughness, surface morphology and temperature generated on the work piece. The castor oil and soybean blend produced the lowest surface roughness, Ra = 0.0738 μm & Rz = 0.4299μm, with near absence of deep grooving and smearing of chip material on the surface, in comparison with other blends due to enhanced rheological properties.

Abstract
The natural fiber reinforced composites are highly utilized in the applications of building and construction industry, storage containers, transportation industry and in other industrial applications. The natural fibers are preferred for its distinct properties than synthetic fibers. Natural fibers are economically cheaper, recyclable and ecologically biodegradable. Many studies were proposed by the researchers to improve the machinability and mechanical behaviour of natural fiber reinforced composites. The addition of filler material is a kind of approach to improve the property of natural fiber reinforced composites. In this study the composite laminates are created by reinforcing bi-directional bast type jute and unidirectional leaf made sisal fibers into an epoxy LY556 resin matrix material. The silicon carbide (SiC) is used as filler material. Two types of composite laminates are manufactured. The first sample is considered in the ratio of 70% epoxy resin to 30% Jute + Sisal fiber composition without any filler material. The second composition includes the ratio of 70% epoxy resin to 30% Jute + Sisal fiber along with 10% SiC as filler material. The hardner HY951 of 10% is used in both compositions. The machining operation was performed by using HSS twist drill for three different machining parameters (Drill bit type, Spindle speed and Feed rate). The circularity and surface roughness are considered as output parameters. The machining is performed in the range of 20 different combinations as directed by the RSM software. The conformation tests are carried out to validate the RSM results. The optimization results shows that the sample with SiC filler exhibits better machinability behaviour than sample without filler material.
