Publisher : Widyagama University of Malang

In the animal feed industry, steam is used in pellet making machines. In this process, steam from the boiler is distributed to the pellet mill through the pipe. The purpose of this study is to observe the waste of electricity costs of operating a boiler by calculating heat loss in a distribution pipe. The method of assessing heat loss is done by calculating losses caused by heat loss in the boiler distribution. Then make a calculation application model based on the data obtained. From the data analyzed, the amount of heat lost in the non-insulating distribution pipe is 0.766 kJ/s with a loss of Rp 5.628,600 operating costs per month compared to heat loss in an isolated pipe condition of 0.047 kJ/s with losses which cost slightly more than Rp 368 190 / month. This heat loss calculation process is made on an android application by entering the calculation formula on the program and the data that has been obtained.

The role of error detection and error correction for the data bit by the receiver is very important because the sender does not need to repeat the transmissions. Thus, the speed and reliability in transmitting data information can be maintained. This study aims to implement simulation the Forward Error Correction (FEC) method in verifying and correcting data errors received by using simulation. To support FEC method, study utilizes visual basic software so that it can be used as one of the quasi-experimental modules in the data communication laboratory. The Forward Error Correction (FEC) method is a method that can correct data errors in the receiver. This method uses simulated Hamming codes on the computer so that the detection and correction process can be clearly demonstrated on the monitor screen. This simulation can be used as a quasi-experimental module in a data communication laboratory. The simulation results show that the Hamming code (17, 12) codec has been running as expected.

Lahor Reservoir was built and functioned as a water provider for agricultural activities, flood control, electricity generation, tourism activities and inland fisheries. This reservoir is one of the inflows of the Sutami reservoir which is the largest reservoir in East Java. This Lahor Reservoir is drained by three rivers, namely the Lahor River, Leso River and the Dewi River, which flows through housing and paddy fields, allowing the entry of organic and inorganic materials from various activities around the rivers and reservoirs. The aim of the study was to assess the physico-chemical parameters of the Lahor reservoir during the dry season. This research was conducted between March and April 2018. Water quality analysis was carried out in the Laboratory of Environmental Engineering Department of ITN Malang. The study was conducted by survey method and sampling method. Measurement of physical and chemical parameters of the waters was determined at 4 stations and each station consisted of 5 sampling points with different depths. Data analysis using descriptive statistics (mean, graph). The assessment of the temperature in the waters of the Lahor Dam ranged from a value of 24-28o C, turbidity with a value of 0.4 NTU, DO values from surface to base increased significantly with values of 29.1 mg / L, 33.9 mg / L and 34.3 mg / L and still meet the minimum water requirements for aquaculture. The high BOD value at the Lahor reservoir outlet is influenced by the accumulation of organic substances from several inlets and dam waters. Phosphate values are higher along with water depth and Fecal Coli ranges from 1-2 MPN / 100 mL at all sampling points. In general, the Lahor reservoir water still meets the quality standards for class I waters.

Publisher : Widyagama University of Malang

This research explains the investigation of fin spacing for heat transfer enhancement in the finned tube heat exchanger. The objective of this paper is to recommend the optimum fin spacing for heat transfer enhancement. Three different types of tube and spacing are identified through the simulation from Ansys software. The data between simulation using Ansys Fluent and published literature were being compared. Graph of total pressure, Nusselt number and total temperature have been plotted to make the comparison. Result obtained showed that were a bigger agreement between the simulation and published literature for both types of the tube which are circular and elliptic. From the analysis, there were considered two types of arrangement for the different types of tube. From that, the aligned arrangement is the best for heat transfer enhancement compared to the staggered. For the effect of spacing, there was three spacing which is 1.7 mm, 1.8 mm, and 2.0 mm spacing with velocity and the total heat flux is set to be constant (v =1.4 m/s; q = 500 W/m2). For the circular tube, it can be seen that the wider of the fin spacing gave the best heat transfer enhancement in the heat exchanger. Different from the circular which is 1.8 mm spacing is the best for heat transfer enhancement. Other types of tube are a flat surface which is comparing with the variations of Nu vs Re with different heat flux. Then, the result showed that as the Re is increased the Nu will also increase. In the other side, it is recommended for future work to do the real model dimension followed to import to the Ansys instead of assuming the model is symmetrical.

Publisher : Widyagama University of Malang

This research presents the application of Acoustic Emission (AE) sensor to explore the feasibility of an AE signal in the process of monitoring the engine oil viscosity on different condition of mileage during the engine operation. The viscosity experiment was performed in a prior stage of the experiment using four samples of SAE 5W-30 engine oil with the different condition of mileage. On the next occasion, the AE signal was acquired on three cylinders of a four-stroke gasoline engine with a cooling water system which operates using the previous lubricant sample. In this experiment, the AE sensor was bonded on the outside of the engine block and located at the oil filter and oil sump location. It was found that the AE energy value is capable of determining the variant of the engine oil viscosity. The results from this project show that via AE technology proved to be feasible for the development of a real-time lubricant condition monitoring which was believed to be a new technology in the automotive industry.

Spot Speed versus Speed Limit on Malaysian East-Coast Expressway Sulistyo Arintono
JOURNAL OF SCIENCE AND APPLIED ENGINEERING Vol 2, No 1 (2019): JSAE
Publisher : Widyagama University of Malang

Speed is one of the important causal factors for accidents on the road. This study aims to investigate the effectiveness of the speed warning sign on Malaysia’s East Coast Expressway where the rate of accident is high. Two points were selected, one representing locations far from any speed related warning sign, and one location immediately after a speed warning sign is in sight, to assess significance of the differences of the spot speeds. Results of the analysis suggest that the majority of vehicles (63.24%) travel over the speed limit, and that the speed warning sign does function in reducing the mean spot speed. However, the speed reduction is not to the desired level, i.e. under the speed limit. Other strategies have to be introduced to achieve the target.

JOURNAL OF SCIENCE AND APPLIED ENGINEERING Vol 2, No 1 (2019): JSAE
Publisher : Widyagama University of Malang

This research project is focusing on the leakage detection in the pipelines using wavelet and cepstrum analysis. To fully complete this research project, experimental and analysis by using signal processing are required. This research project proposed a technique which is a transient method. The basic principle is the fact that water spouting out of a leak in a pressurized pipe generates a signal, and this signal contains information to whether a leak exists and where it is located. The present transient methods for finding leaks are mainly based upon correlation analysis, where one sensing device is installed at each side of a leak. This method is hard to operate because it needs many operators to operate it due to equipment in different place. This research project proposed a wavelet transform method to detect leakage in the pipeline system. The experimental results show appears to improve the ability of the method to identify features in the signal.

Ride comfort in vehicle transportation is quite complex, and it depends on various dynamic performance criteria and subjective perception from the car passengers. Vibration discomfort from various factors such as vehicle conditions, the speed of the vehicle, road surface condition, vehicle load, and operating condition can lead to poor ride comfort. Driver seat will be the main part of a car that needed to get a dynamic comfort. Comfort and safety are major factors that need to be considered. To ensure the safety for passenger, the driver must feel comfortable while driving. The objective of this project is to analyze the vibration at the seat of a Proton Wira at different speeds, different loads and different road surfaces. In this project, use six different speeds. Vibration data from two types of road and three different loads are collected using two accelerometers sensor that place on driver seat and seat frame. The rough surface will cause a car to generate more vibration. The results for frequency and time responses show that the vibration increases at the dirt road.
