Abstract

Effect camshaft duration on performance of 110 cc gasoline engine carried out by comparing the duration of standard and modified camshafts of 303.5o to obtain maximum power produced by 110 cc smash type Suzuki engine and its effect on fuel consumption. This study aims to know of, (1) torque machine with modification in duration camshaft, (2) knowing total fuel consumption (FC), spesific fuel consumption (SFC), and thermal efficiency of the standard engine and engine has modified in the duration of its camshaft. A method of testing in the research was done with to the chassis of dynamometer as for testing done in PT.Suzuki galesong pratama through adhering to a standard testing suzuki that has been set. The results showed a change in the value of power and torque on standard engine power obtained by 5.3 HP or 3.88 kW to 6.0 HP or 4.63 kW with a torque value of 6.14 N.m, then decreased at 9000 rpm rotation of 5.02 Nm. While the duration of power modification camshaft obtained is 7.5 HP or 5.60 kW with a torque of 8.65 Nm, it also decreases at 9000 rpm of 7.9 HP or 5.89 kW. The significant effect occurs at 9000 rpm. Standard camshaft FC value is obtained at 0.8946 kg / h, SFC = 0.1932 kg / kWh. For duration of modified camshaft, at 9000 rpm,  FC value obtained was 1.6526 kg / h, SFC = 0.2806 kg / kWh. From these results, it is known that an increase occurred in the FC value with a difference of 0.758 from previous results with an SFC of 0.0874. Furthermore, thermal efficiency obtained by 50.01% at 6000 rpm decrease by 40.29 % at 9000 rpm for standard camshaft. The duration of a modified camshaft was obtained by 53.34% at 6000 rpm and decrease by 30.02 %  at 9000 rpm.

Abstract

Along with its development, car manufacturers are increasingly improving safety and security features in each of their products. Currently, this element of safety and security has become an important target in the development of the existence of various features that exist in a vehicle. In this study, the power back door feature is implemented by using the kick foot sensor as input data to open and close the trunk of the vehicle through the actuator. This feature uses a foot sensor so you don't have to press any buttons, just point your foot under the rear bumper and the sensor will automatically read and open the trunk door. This feature is very helpful for passengers who want to put their luggage in the trunk but have both hands to carry items such as bags or plastic shopping bags. There are several stages carried out in this research. In the first stage, the specification of the required actuator motor, including force and torque, is carried out by analyzing the free body diagram to be able to open and close the trunk. In the second stage, the trunk door is tested when the condition is open and close. From the test results, the average time to open the trunk is 11.79 seconds, while the average time to close the trunk is 11.56 seconds. The time obtained is faster than the initial design target set, which is 15 seconds both when opening and closing the trunk. While the sensitivity of the motion sensor can range from 20 mm to 400 mm when the foot is directly under the sensor.

Abstract

The numerical study of pressure drop on a tandem cylinder with the addition of a splitter plate and a vortex generator with the effect of a blockage ratio has been completed. The cross-sectional height and diameter of the cylinder in this study used H= 125 mm and D= 37.5 mm, respectively. The blockage ratio is 30%. The Reynolds number (Re) is 52100 ≤ Re ≤ 156000. The distance between cylinders is 5 to 8, where “s” is the distance from cylinder one to cylinder two. The dimensions of the splitter plate are L=D, L=1,5D, and L=2D where "L" is the length of the splitter plate, while the thickness in this study is 1, 75mm. The dimensions of the vortex generator in this study are used those of Hu, et al. [6]. The angle of the vortex generator is = 350 while the length of the vortex generator is H = 3 mm. All variations of this numerical study were carried out using the URANS (Unsteady Reynold Average Navier Stoke) method with a Reynolds number (Re) 52,100 Re 156,000. The smallest pressure drop value is obtained at the Reynolds number 52.100 for all variations, while the highest Reynolds number is obtained at Re 156.000. the addition of a splitter plate and a vortex generator, gives a higher pressure drop when compared to a circular cylinder.

Abstract

The plastic waste composite molding tool with coconut fiber is designed with the aim of converting HDPE plastic waste, especially drink bottle covers mixed with coconut fiber into a product in the form of a composite board (panel) that is more useful. The dimensions of the mold are 410 x 540 mm, the tool height is 850 mm, the width is 600 mm, the length is 600 mm, the temperature of the installed heating elements is around 200-250 degrees for 12 pieces, 220 V 1000 watts, while the press uses a 10 ton hydraulic jack. While the heating temperature for pressing the composite board is set in the range of 130 – 180 oC. From the results of the first printing press with iron plate material, the resulting product is sticky on the plate surface, the second test is coated with aluminum foil, the resulting product is less than perfect because the surface is uneven. , while the third test was coated with a stainless steel plate, the resulting product was better than the previous results. This research needs to be improved in order to assist the government in handling plastic waste. In addition, the results of products with this tool will help improve people's skills and improve the economy of the products of this tool.

Abstract

In the fish pond ecosystem there are various factors that can inhibit fish growth or even kill fish,  one of which is the water factor,  the water itself has various factors,  one of which is the quality of PH levels and amonia levels. Therefore,  this paper discusses the design and manufacture of a control device for PH levels and amonia levels to make it easier for farmers to check PH levels and amonia levels in the pond. This control device uses a DFROBOT V.2 sensor as a PH sensor and a DS18B20 sensor as a temperature sensor as well as an Arduino UNO controller. The method used to control amonia is by comparing the data from PH and the temperature in the pool water,  this tool will work if the amonia level is higher. from 0.8ppm by activating the aerator to keep the amonia in the pool water normal. Meanwhile,  to maintain the PH of the water more than 6 and less than 7,  it is necessary to add pond water by activating the water pump. The results of this study can be used as a reference for future research for the development of Arduino Uno-based PH and amonia level control devices.
