Published: December 2019

Packaging material needs to be packaged properly in order to protect it from contamination of other substances that can affect product quality. Moisture level of some products is high due to its moisture content and may result in the growth of Aspergillus niger fungus on the packaging. The use of thiabendazol in coating has been known as one of the methods to inhibit fungal growth on packaging. The purpose of this study is to determine the effect of coating on inhibition of fungal growth. Fungal resistance test was conducted by using Elmes method, disk diffusion and water absorption of packaging substrate (Cobb method). Carton as packaging material was coated using thiabendazol coating with various thicknesses (1μ, 2μ, 3μ, 4μ, 5μ and 6μ). Uncoated carton as control negative and nistatin as control positive. The optimal thickness of coating was 5μ with inhibition zone of 2.10 cm-21 mm. As thickness of coating increased, then the larger zone of inhibition produced. These results indicate that the resistance of the antifungal coating was getting stronger. Coatings contain thiabenzol can inhibit growth of fungal on the packaging.

Published: December 2019

Strong currents can flow in a closed circuit. Calculation of current strength involves calculating the voltage source, resistance to the circuit, and circuit resistance. Kirchoff’s Law I and II can be applied to calculate current and voltage strength in a closed circuit. The obstacle in calculating using Kirchoff’s law is if the number of loops is large so it requires many mathematical equations. The results of this study are the program that can perform calculations in a closed circuit consisting of one and two loops with two voltage sources, five main obstacles, and two internal obstacles. The value of the resistance itself can be determined by inputting the color code on the resistor rings. In addition, an explanation of how to calculate with the law I and II Kirchoff is also included in the program.

Published: December 2019

Images can be produced by tools such as cameras, satellites or scanners. The process of transferring images from these devices can cause interference in the form of noise. Damage to photos or images is something that cannot be avoided, where this damage is usually caused by a time factor, a factor in someone’s accidental handling of a photo, or other external factors. This will cause the photo to be cured until information loss or artistic value occurs. Image processing is a solution to handle or manipulate an image, in other words in image processing is also offered a technique to deal with the problem above, because handling an image or photo that is damaged is also a process of manipulation of that image. One method of image repair due to noise is through a filtering process by dividing the image into four parts of the actual size, namely the filtered image and the other part are the details of the image where this process reflects the performance of the wavelet transformation method. The results of the trial using the software show the number of filter coefficients affecting the results of filtering with wavelet transformations, where the more the number of filter coefficients daubechies the smaller the visualization of contrast. Repeated decomposition of the image on the wavelet transformation will erode the original image, this is caused by the more pixel values transformed by both the low-pass-filter and high-pass-filter processes.

Published: December 2019

The road network system in the distribution of the freight transport movement has a strategic role to create economic value of goods that is more efficient than the transportation cost component of goods commodity. The increase of expensive oil fuels requires estimated needs for the distribution of the goods traffic movement on a road network. The consumption of fuel oil is estimated based on the value of the energy content needed in the type of vehicle used. Analysis of the fuel oil needs from the movement distribution of road freight transportation is based on variables that determine the need for fuel oil consumption in the type of freight transport. Moreover, the distribution distance, vehicle type and fuel consumption coefficient are variables that determine the need for oil fuel in the loading of the road network system on a macro basis. The results of the road network system loading model based on the all or nothing model method on the regional regional - internal road network of Central Java province were produced = 352.48 + 0.965 with model validation with traffic counting data obtained was R2 = 0.55. The consumption of oil fuel in the road network system from road network loading obtained the highest fuel consumption from the consumption of pick up vehicle material as the largest vehicle consumption. So that from the analysis results of the need for fuel consumption in road freight transport, a new strategy can be made to reduce the use of small transport on the movement of road freight in the road network system.

Published: December 2019

The two basic principles of the problem in assessment are determining whether a test has measured what is being measured and whether a test has been appropriately used to make a decision about the test taker. It is possible that the test developers argue that math tests for example can predict a person’s ability in physics.

Gallium nitride (GaN) has successfully grown at the short time on the sapphire substrate by plasma-assisted molecular beam epitaxy (PAMBE). The great regular spotty pattern associated with the high crystalline structure has generated perfectly on the GaN thin films monitored by RHEED. The hexagonal structure with the smooth surface condition has been obtained expressly through the surface morphology of GaN films. Moreover, the stability of surface composition was obviously achieved on the GaN thin film evidenced by the high percentage of GaN bonding created on the surface of films. Good quality on the surface morphology followed by the reliable stability of surface composition might even be reached through each the high crystalline and smooth surface of the substrate.
