Abstract

The decreasing land area in big cities makes construction progress develop not only vertically upwards, but also downwards. This is done to optimize the land use. One of the things is the construction of a basement as a parking lot, storage space, and other functions to be neatly organized and safe. There are numerous employment risks in basement work that can result in building failures that hinder other construction activity. This research was conducted at a company that focuses on the business of guitar manufacturing, retaining walls, and soil improvement in three high-rise building construction projects that are currently building, and experiencing difficulties in identifying the main risks in diaphragm wall work. The soil conditions are different at each project site, which is not the same as the superstructure work. It is more typical and the quite large project value reaching more than 100 billion than can be classified as a major construction project. The risks that will be encountered in its implementation will also be large. The steps involved in the research were risk identification, risk qualitative analysis, and extreme risk response planning by experts. There were sixty-four (64) identified risks relevant to the project construction phase, classified into eleven categories. The risk was then simulated to obtain high risk and control risk plans that would be carried out when the high risk occurs. There are four high risks, namely the damaged or non-compliant construction materials, inaccurate specifications, delays in the execution of constructor work, and slope failure during excavation.

Abstract

Commercial mayonnaise currently available is full fat mayonnaise with high oil content (70-80%) which can be harmful to health when consumed in the long time. Reduced fat mayonnaise (RFM) as an alternative mayonnaise, which reduces the oil content causes the emulsion changes so a stabilizer is needed. The stabilizer that can be used is porang flour which rich in glucomannan. This study aimed to determine the physicochemical and sensory of RFM with variations in oil (M) (40%, 50%, and 60%) and porang flour concentration (P) (0.1%, 0.2%, and 0.3%). This study used a Completely Randomized Design. Physicochemical parameters include water content, ash content, fat content, protein content, pH, viscosity, emulsion stability, color and emulsion droplets. The result showed that RFM has water content content 26,14 - 44,25%, ash content 0,52% - 0,60%, fat content 37,61% - 64,11%, protein content 3,35% - 3,76%, pH 4,07 - 4,17, viscosity 639,90 cP - 9250,00 cP, emulsion stability 99,98% - 100%, and color L* 83,92 - 85,72, a* 2,67 - 5,92, b* 20,28 - 29,25, and chroma 20,75 - 29,48. M2P3 was the selected formulation with higher acceptance for parameters such as color, aroma, texture, taste, and overall compared to the control mayonnaise.

Abstract

This paper presents a hardware inference accelerator architecture of quantized deep neural networks (DNN). The proposed accelerator implements all computation in a quantize version of DNN including linear transformations like matrix multiplications, nonlinear activation functions such as ReLU, quantization and dequantization operation. The hardware accelerator of quantized DNN consists of matrix multiplication core which is implemented in systolic array architecture, and the QDR core for computing the operation of quantization, dequantization, and ReLU. This proposed hardware architecture is implemented in Verilog Hardware Description Language (HDL) code using modelsim. To validate, we simulated the quantized DNN using Python programming language and compared the results with our proposed hardware accelerator. The result of this comparison shows a very slight difference, confirming the validity of our quantized DNN hardware accelerator.

Abstract

XYZ Sugar Factory is a manufacturing company that produces processed sugar cane with the main product being white crystal sugar of the Super High Sugar (SHS) type. The problem found at the XYZ Sugar Factory was that there were defects in white crystal sugar products amounting to 7,359.1 tons with a defect percentage of 11.12%. This study aims to determine the types and causes of defects, as well as suggestions for improvements. The methods used are Fault Tree Analysis and Failure Mode and Effect Analysis. The results of the research show that the types of defects that occur in white crystal sugar products are sugar color defects and sugar grain size defects. One of the causes of sugar color defects is excessive levels of additional raw materials, while one of the causes of sugar grain size defects is the insufficient cooking duration of the sugar crystals. The results of FMEA calculations obtained the highest RPN value, namely sugar color defects with an RPN value of 140 and then grain size defects with an RPN value of 120. Proposed improvements for the company are to make appropriate measurements for additional raw materials to help with the production process and provide more routine training to employees regarding the use of machines. production.
