Abstract

The occurrence of various disruptions and damage to equipment and electrical installations begins with a significant temperature increase in it. The temperature increasing in electrical equipment and installations will also increase the consumption of energy or power required. Previous technology used a temperature sensor and current sensor which had to be installed in the environment to be monitored. The temperature measurement system without touching the surface which is measured using infrared rays is a new breakthrough that really helps maintenance and repair. Also with the existence of a temperature sensor arranged in an array, it can map the existing temperature so that it can provide a better picture for analyzing the symptoms that  occur, compared  to using a temperature sensor that measures one point only. A temperature imaging camera is currently very expensive, making procurement a bit difficult for laboratories dealing with electrical equipment and installations. In this research, we will try to make an inexpensive temperature imaging camera using the MLX90640 sensor and the ESP32 microcontroller. Bicubic interpolation is used to  enlarge the resulting image obtained  by the MLX90640 sensor. The MATLAB program is   used to simulate and create an overall temperature imaging camera system. Tested and compared with two other interpolation methods to ensure that bicubic interpolation can produce better magnified images.

Abstract

Borax is a carcinogenic compound which is dangerous to the body. The flame method is one of the qualitative laboratory testing that usually used to determine the Borax compound in food. The method not only needs H2SO4, methanol, furnace equipment which is prices, but also needs long time because of the graying process. The research aims to make a simple borax test kit (simple method) by extracting anthocyanin substances on the skin of purple sweet potatoes and testing the borax compound in food samples. Materials and tools used are purple sweet potato skin, 96% ethanol, filter paper, knives, cutting boards, measuring cups, beaker glass, food scales and petri dishes. The results of the borax test kit that have been made are then tested using the borax standard as the gold standard and it showed that there was color changing of the test kit, i.e from pink to blue. The borax test kit was also tested on four food samples that possibly contained borax, i.e gendar crackers, white tofu, meatballs and noodles. Gendar crackers was the only food sample that contain borax. Therefore, it was concluded that the borax test kit made from filter paper containing anthocyanin can be used as an alternative tool in qualitatively testing of borax in food

Abstract

The content of organic matter in barren land and padas has been determined spectrophotometrically and titrimetrically. Soil samples were taken from four locations, each of the two locations of barren land (I and II) and two locations (I 'and II'). The content of soil organic matter at depths of 15, 50 and 90 cm determined spectrophotometrically, is 24.48; 17.29 and 9.07% (Location I), 19.64; 15.92 and 6.24% (Location II). With the titrimetry method on solid soil, the yield obtained is 1.30; 0.94 and 0.76% (Location I '), 0.64; 0.46 and 0.31% (Location II'). It appears, that the deeper the content of organic matter the lower the soil. When compared with barren land, the content in padas is lower.

Abstract

In the foundry laboratory at Bandung Polytechnic for Manufacturing, there is a student practicum program where the student learns several molding methods that are often used. One of these methods is a vertical pouring method. This is a one of mold method in the foundry process where the object is positioned vertically (vertically) with the inlet position either at the bottom of the object or at the top of the object. In this experiment using the vertical pouring method with direct pouring from a top. This method is usually used for objects that are plate shaped or cylindrical. The advantage of this method can control shrinkage and minimizes the mold area. In the process, where the object will be made in limited quantities, the mold is tied and buried in sand. The problems are processing time is longer than Cup and Drug molds, and wears a lot of sand. For this reason, a tool for clamping vertical molds is designed. This tool is expected to reduce use of sand, and reduce processing time. This tool is made of steel. vertical pouring method becomes more effective and efficient by using clamps
