Abstract

The abundance of solar light in tropical countries is the advantage of the utilization of solar energy. Increasingly expensive electricity forces buildings to use passive ventilation as building coolers. One of them is the use of the stack effect through the solar chimney. The absence of residential buildings that use the solar chimney as part of a passive ventilation system makes the need for prototypes for residential buildings. The application of solar chimney to homes in Jakarta is something new. Six types of the solar chimney have been tested on a prototype, one-story residential houses in Jakarta. The location was assumed to be in the densely populated area of South Jakarta. Wind velocity ambient data using Rubber locations. Using Ansys 16.0, simulations have been carried out, and solar chimney with double-full roof collector was able to induce a wind velocity of 0.41 m/s on average

Abstract

The rainy season will have a severe problem to the transportation sector (including heavy-duty trucks) in the off-road area in Indonesia, especially in areas that do not have permanent access roads (asphalt or concrete roads). For heavy vehicles, especially oil palm transport trucks will experience such obstacles, including slippage when crossing muddy dirt roads, and it will have an impact on the logistics delivery process. Therefore, it is necessary to design a support system, especially on the wheels, to reduce the risk of skidding or rolling on truck-type vehicles. In this work, the design of the anti-slip shoe wheels of the colt diesel double type truck (CDD) is used on the rear-wheel-drive as a tool for handling the slippage. In this design, the maximum traction factor of the wheels based on the calculation on the rolling resistance should be higher than 594 kg. The next step is to determine the value of soil cohesion and soil internal friction angle obtained from the previous studies. In this study, a calculation simulation was carried out to accomplish the design of the main components of the anti-slip of a truck wheel in the form of a traction rod fin. The design is namely U channel profile steel based on SNI 07-0052-2006 type U50, U65, and U80 with dimensions of the fin depth (z) are 3.8 cm, 4.2 cm, and 4.5 cm and length of 30 cm. The results show that the three types of U channel iron used for the anti-slip shoes are useful for freeing trucks from slippage with a total load of 12 tons. Thus, the truck will be safe when crossing the muddy roads with clay, muddy clay, and sandy loam under the following conditions: minimum cohesion number of 0.008 kg/cm2, minimum internal friction angle in the soil of 4.631°, and the maximum water content of 59.6%.

Abstract

Nowadays, the internet and social media grow fast. This condition has positive and negative effects on society. They become media to communicate and share information without limitation. However, many people use that easiness to broadcast news or information which do not accurate with the facts and gather people's opinions to get benefits or we called a hoax. Therefore, we need to develop a system that can detect hoax. This research uses the neural network method with Long Short-Term Memory (LSTM) model. The process of the LSTM model to identify hoax has several steps, including dataset collection, pre-processing data, word embedding using pre-trained Word2Vec, built the LSTM model. Detection model performance measurement using precision, recall, and f1-measure matrix. This research results the highest average score of precision is 0.819, recall is 0.809, and f1-measure is 0.807.  These results obtained from the combination of the following parameters, i.e., Skip-gram Word2Vec Model Architecture, Hierarchical Softmax, 100 as vector dimension, max pooling, 0.5 as dropout value, and 0.001 of learning rate.

Abstract

In the machining of metal cutting, cutting tools are the main things that must be considered. Using improper cutting parameters can cause damage to the cutting tool. The damage is Built-Up Edge (BUE). The situation is undesirable in the metal cutting process because it can interfere with machining, and the surface roughness value of the workpiece becomes higher. This study aimed to determine the effect of cutting speed on BUE that occurred and the cutting strength caused. Five cutting speed variants are used. Observation of the BUE process is done visually, whereas to determine the size of BUE using a digital microscope. If a cutting tool occurs BUE, then the cutting process is stopped, and measurements are made. This study uses variations in cutting speed consisting of cutting speed 141, 142, 148, 157, 163, and 169 m/min, and depth of cut 0.4 mm. From the results of the study were obtained that the biggest feeding force is at cutting speed 141 m/min at 347 N, and the largest cutting force value is 239 N with the dimension of BUE length: 1.56 mm, width: 1.35 mm, high: 0.56mm.

Abstract

Self Compacting Concrete (SCC) is concrete with high fluidity so that it can flow and fill the spaces in the mold without the compaction process. This study discusses the effect of the adding of kaolin and polypropylene fibers in order to increase the flowability, compressive strength, flexural strength, and tensile strength in self-compacting concrete. The additional material of kaolin was 5%, 10%, and 15% of the cement weight. The polypropylene fibers were 1%, 1.5%, and 2%. The flowability test, which was used, was Table flow, V-Funnel, and L-Box. Compressive strength testing was conducted when the concrete was 7, 14, and 28 days old. The flexural test was performed with a measurement of 150 x 150 x 600 mm as many as 18 specimens tested at the age of 28 days. The results showed that the addition of kaolin and polypropylene fibers met the flowability specifications of self-compacting concrete. The addition of polypropylene can increase the flexural strength and tensile strength of the concrete beam, but cannot increase the compressive strength of self-compacting concrete.
