Technology can be used as a preventive measure to avoid theft. One technology that can interfere and even make the perpetrator cancel the robbery is an alarm. With the sound of the alarm, the thief can be surprised and will immediately save himself because he is worried about being caught. Until now, various alarm technologies have been studied, from simple to complex. There are also many sensors used as triggers for alarm activation. This study created a simple anti-break alarm that is not easily turned off using a magnetic switch and relay. Several parameters are measured to determine the performance of the input and output of the alarm such as voltage and current, then a consistency test is carried out from the alarm that was created. The results obtained were that the alarm functioned properly. The alarm can sound when the door is opened then continues to sound and does not break when the door is closed again. The alarm also works consistently after 100 tests.

The turning process in manufacturing is used as the formation of cylindrical components, threads and drilling. ST41 steel has the ability to form, weld and treat, so it is used as a material for tools and automotive components. Insert tools with long life (live time), resistance to wear and high temperatures are better than conventional tools, making the type of insert tool used for various cutting processes. The quality of turning is determined by the selection of cutting parameters that are appropriate to the type of material being cut and the tool used. Lathe parameters are feed rate, cutting speed, deep cut. Feed rate parameters affect process time, surface roughness and tool wear. The use of excessive feed rate causes surface roughness outside tolerance and large tool wear. Therefore, research on ST 41 steel with insert tools to obtain optimal parameters is needed. Research using the experimental study method aims to analyze the effect of tool wear values on changes in feed motion and surface roughness. Turning of ST41 steel on a GUT C0636D X 1000 lathe, CCMT 060204 insert tool, 0.6mm depth cut, 300 rpm cutting speed and feed rate variation of 0.1620, 0.3250, 0.8120 mm/rev. The results of the study measured the tool wear value increasing against feed rate and surface roughness. The highest tool wear value is 0.021 grams, namely with a feed rate variation of 0.8120 mm/rev, a surface roughness of 8.961 μm is obtained. The lowest tool wear value is 0.005 grams, namely with a feed rate of 0.6120 mm/rev, a surface roughness of 5.300 μm is obtained.

Vehicles with conventional engines produce heat from combustion in the engine, so that the engine temperature is stable, a radiator water system is needed. The purpose of this study was to determine the effect of water coolant and plain water temperatures on fuel consumption. The method used was to test 3 variations of engine speed, namely 1000, 1500 and 2000 rpm on fuel consumption and engine temperature. The results obtained showed that the average fuel consumption was the same when using water coolant and plain water at an engine speed of 1000 rpm and the water coolant temperature was 3 oC lower than the temperature of plain water. While the average fuel consumption when using water coolant was 17 mL lower than using plain water at engine speeds of 1500 rpm and 2000 rpm, with a temperature drop of 1-3 oC. So, fuel consumption and temperature were lower when using water coolant than when using plain water.

Glycerol, a byproduct of biodiesel production, can be transformed into value-added compounds such as triacetin, which serves as an effective octane booster in gasoline. This study investigates the acetylation of glycerol with acetic acid using calcium oxide (CaO) as a heterogeneous catalyst. Catalyst concentrations of 1%, 2.5%, 5%, 7.5%, and 10% were tested under reaction conditions of 100C for 180 minutes. The resulting products were analyzed using gas chromatographymass spectrometry (GC-MS) to identify acetylated derivatives. Among the tested conditions, 5% CaO yielded the highest triacetin content. The acetylated product was then blended into gasoline at a 5% concentration. Fuel testing showed an increase in the Research Octane Number (RON) from 84 (pure gasoline) to 93 with the addition of triacetin, along with slight increases in fuel density and viscosity. These findings highlight the potential of CaO-catalyzed glycerol acetylation for producing high-performance fuel additives.

The availability of solar energy has great potential for application in the agricultural sector. Electrical power from photovoltaic cells or solar panels mainly depends on sunlight at certain times. The use of this technology can be applied to pump drives in agricultural irrigation systems. In this research, we try to measure a certain time with the efficiency of components from using solar photovoltaic (SPV) with the water discharge produced by the pump on these components. From the experimental results, it was found that the best efficiency was at 14.00 WITA with an efficiency of 57% with the panel facing directly to the sun. From pump testing, it was found that the average water flow was 20.95 liters/minute. From these performance tests, Indonesia itself has sufficient levels of solar radiation to use solar panels as an alternative to sustainable resource.
