Abstract

This development research aims to make a tool and test its ability to absorb the heat in light radiation by colored surfaces (black, dark green, blue, white). The benefit of this research is to present a simple laboratory that can be used in physics education class as a test tool for heat absorption. The research method that applied is Microcomputer Based Laboratory (MBL). The software that used is LabVIEW which connected to Arduino Uno hardware and heat source. The appropriate set of tools and materials is then tested for eligibility. The feasibility test of the device is reviewed from the aspect of content, linguistic, presentation and graphic by an expert validator as well as the compatibility of the findings with the theory. The results found that the darker the color of the object, the greater the ability of heat absorption and vice versa. Changes in power at a light source can affect changes in maximum temperature in the color absorption of heat. The greater the power provided by the light source, the greater the increase in maximum temperature. This development research concludes that the tools are feasible to use and appropriate based on existing theories.

The Effect of Ionic Silver Nanoparticles Concentrations on the Inhibition of Lactobacillus casei and pH of MilkABSTRACTTechnological developments support the creation of various nanoparticles that can be utilized, one of which is silver nanoparticles. This study aims to determine the effect of ionic silver nanoparticle concentration on Lactobacillus casei growth inhibition, pH change and curdling of UHT milk. Variation in the concentration of ionic silver nanoparticles of 5, 10, 15, and 20 ppm was tested for their characteristics through UV-VIS spectrophotometry, showing the wave peaks at 413–430 nm, and through the PSA test resulting in the Z-average of 87.2 nm. Ionic silver nanoparticles were tested against L. casei using the Kirby-Bauer diffusion method for 72 hours. The test results showed a change in the clear zone that tended to increase for the concentration of silver nanoparticles 5, 10, 15 and 20 ppm with the gradient values of 0,0032; 0,0280; 0,0395; dan 0,0317, respectively. Tests for pH and UHT milk curdling were carried out for 78 hours and showed that ionic silver nanoparticles tended to be more able to maintain milk pH ±30 hours and curdling ±24 hours longer than milk that was not treated with ionic silver nanoparticles.Keywords: electrolysis; Lactobacillus casei; milk; nanoparticles; silver ABSTRAKPerkembangan teknologi mendukung terciptanya berbagai nanopartikel yang dapat dimanfaatkan, salah satunya nanopartikel perak.

Abstract

This study aims to determine the feasibility of a composite board made of hemp fiber and banana stem fiber with Poly Vinyl Acetate (PVAc). Making the composite board begins with the preparation, drying, weighing the raw materials according to the weight ratio, mixing, pressing and cutting the finished composite board according to the size required in the test standard. Composite board characteristic testing includes: moisture content, thickness swelling, density, flexural strength and tensile strength of the composite papn. The test results on the composite showed that the more the value of the banana stem fiber used as a combination for the hemp fiber, the more the feasibility value of the composite board did not meet SNI standards. However, for the bending test, all categories of fiber combinations were not feasible because the sample specimens were not stiff due to PVAc which only functions as an adhesive (not a reinforcement).

Abstract

Natural resources on Earth consist of abiotics and biotics. Water, including biotic natural resources is one of the most important elements in supporting the survival of human life. One of water source which was widely used by resident around the Yogyakarta State University was the water of Institute of Development and Quality of Education Assurance (Lembaga Pengembang dan Penjamin Mutu Pendidikan) of Yogyakarta State University. This water resource was used to fulfill the needs of employees, the institute visitors, and traders around Karangmalang Culinary Park. However, the prior observation showed that the color of the water was prone to muddy and contains many sediments substances. This research was aimed to filter the water of that institute into pure water according to the physics parameter. This research was conducted by utilizing biomass waste in the form of teak, husk, and coconut fiber to be processed into active charcoal which later used to filter the water. Additional materials used in this research were sand and gravel. The result of water’s total dissolve solid (TDS) has decreased by using the three active charcoal of biomass waste. Among those activated charcoal, the carbon which formed by teak showed the most significant result. Furthermore, in Fe content test, the most significant result of decreasing Fe content was showed by activated charcoal from husk base material. It can be concluded that the most effective activated charcoal material was formed by teak biomass waste which has a large pore structure.Keywords: active charcoal, biomass waste, filtration.
