<![CDATA[Company YS participates in managing the natural gas network by creating a Metering Regulating System (MRS), which is a tool to measure gas usage and damage to the natural gas network. Based on the data obtained, the MRS delivery process was often not in accordance with the agreed schedule, there was a delay of up to 46%, namely 50 days late from the planned schedule. To overcome these delays, waste reduction is carried out by mapping the overall condition of the company in Value Stream Mapping (VSM) and mapping in detail with the Value Stream Mapping Analysis Tools (VALSAT). In the VSM method, a Current Value Stream Mapping is carried out which then identifies the waste in which the correlation score between the wastes is described in a matrix called the Waste Relationship Matrix then followed by the calculation of the Waste Assessment Questionnaire. Then in the VALSAT method, further waste identification was carried out using seven tools. The most influential percentage of waste that has been obtained is then searched for the root cause using a fishbone diagram and then eliminated and depicted in the Future Value Stream Mapping. The most influential waste in the fabrication process is Waiting and after repairs according to the recommendations, the lead time is obtained from 41,822.60 minutes or 99 working days to 35,055.60 minutes or 83 working days so that the fabrication process can be completed 3 days faster than scheduled.]]>

<![CDATA[According to the Ministry of Environment (KLH), Indonesia's average population produces 189 thousand tons of garbage per day. Of this amount, 15% is plastic waste or 28.4 thousand tons of plastic waste per day. The famous handling of plastic waste is 3R (Reduce, Reuse, Recycle). Reduce is reducing the purchase or use of goods made from plastic, especially disposable items. Reuse is the repeated use of plastic-based items. Recycle is recycling goods made of plastic. The method used in this design study is to use SolidWorks software by combining the literature study VDI221 to obtain a variant of the design results that will be used. The study results do a plastic bench machine that is integrated to produce plastic seeds, which are PET-shaped, which are extruded in a device that has been brewed. From the results of the design in the data processing and design specifications of the PET plastic waste-processing machine with the extruder method, the construction consists of several units, namely, Shredder unit, Extruder unit, Cutter unit, and Machine frame. The shredder unit serves to destroy plastic waste that is still intact in pieces before being processed in the extruder unit. The extruder unit functions to melt PET waste to be extruded using a screw. The cutter unit operates to cut processed extrusion waste into pellet granules. The engine frame is used to support the entire engine unit. The results of the Plastic Waste Extruder Machine design process with an Autodesk inventor are summarized in the following specifications: machine dimensions are 1625 mm long, 300mm wide, and 1325mm high; screw extruder uses a metering screw type with a diameter of 50.8mm (2 inches) with a length: diameter ratio of 20: 1, so the screw length is 1016mm, estimated throughput rate = 84 lb/h (42kg / h), the motor used is 5.5 PK (4 KW) with a rotation speed of 1450.]]>

<![CDATA[: Green mussels (Perna Viridis) are a source of seafood consumed by the Indonesian people with a fairly high percentage. The high consumption rate is followed by a high amount of processing waste in the form of shells that are allowed to accumulate. Generally, waste shells are only used as handicrafts or wall decorations. In this study, green mussel shell waste (Perna Viridis) was used as an adsorbent medium to reduce air temperature, besides that, it was used to test motorcycle exhaust emissions. The test is carried out by placing the adsorbent in a cool box which is tested on the heater as a heat source with temperature variations in the control heater 80, 100, 150 and motorcycle exhaust gas with variations in engine speed of 2500 rpm, 3900 rpm, 4700 rpm. The test results on the heater show that the green mussel shells have been able to reduce the temperature by or 35% of the heat source. Furthermore, in testing the exhaust gas of the motor at 4700 rpm with a temperature of 170°C it can be reduced by or 71.48% of the heat source. In addition, the cool box is also able to reduce motorcycle exhaust emissions, especially CO2 by 2,6 %. Thus, green mussel shells can be used as an alternative medium for adsorbents]]>

<![CDATA[There are many racing air filter products on the market with air filter fold gap of 45 microns. However, there has been no research proves that an air filter with 45 microns’ fold gap can increase the performance of a car engine. Based on this, the author is interested in conducting an experimental test analysis of the car engine air filter by modifying the factory standard air filter which has fold gap of 25 microns into an air filter that has fold gap of 45 microns. This study aims to prove whether a 45-micron air filter can increase the performance of a car engine in the form of torque, power, fuel consumption, and mechanical efficiency. The study is conducted by using dynamometer. Analysis of research data uses descriptive statistics with data presentation in the form of tables and graphs. The results of this study indicates that the effect of a 45-micron air filter on a car engine performance is proven to improve car engine performance compared to factory standard air filters with details: torque in car engine increases by 3.05%, power in car engine increases by 1.78%, the specific fuel consumption of the car engine is 1% more efficient, and the mechanical efficiency of the car engine is increased by 0.02%. Based on the research that has been done, it is necessary to do further research regarding the effect of the 45 micron racing air filter on the service life of the piston and valve in the car engine.]]>

<![CDATA[Engine failure is difficult to predict, especially related to the age of engine components. Analysis of engine failure can be done based on the oil seen from the trend of wear rates, predicting the possibility of components that are damaged in the engine. The method used is a combination of oil analysis in order to determine the component that is damaged and determine the age of the component based on the trend of the element value with the Component Meter Unit (CMU) and implement the Failure Mode and Effect Analysis ( FMEA) method to support the analysis by looking at the value of the Risk Priority Number (RPN). The result of this analysis is that there is slightly above normal wear on the Cu and Pb elements, where in the last sample the values for Cu 3 and Pb 5 are Particle Per Meter (PPM). CMU predictions are also generated before passing the threshold of the wear limit based on the value of each element. Fe at 17931 hours, Cu at 25963 hours, Pb at 14417 hours and Al at 16927 hours. Wear is indicated from the FMEA analysis, there are 3 with the highest RPN, namely cutting filter result with RPN 280, noise with RPN 175 and scratch with RPN 160. From these Cu and Pb elements it can be determined which components are the source of damage, namely rocker arm bushings, wrist pin bushings, governor drive and bushings, timing gear thrust bearings, turbocharger bearings, camshaft lifter roller pins, air compressor bearings, rear cluster gear bearings and main and rod bearings. From this research, new research data can be developed, namely if there are additional parameters such as oil viscosity value.]]>

<![CDATA[The food processing industry in every production process always produces waste. One of the food industries in the Jakarta area is the tofu making industry. Waste from the tofu processing process is divided into 2 types, liquid waste and solid waste. Problems that arise include the occurrence of deposition and decomposition of organic matter in water bodies which causes silting of rivers, and causes unpleasant odors. An alternative solution to reduce the pollution load is to use filter media with material from green mussel shells (Perna viridis). Meanwhile, green scallop shells are solid waste for the environment which were used in this study as a filter medium for the liquid waste left over from tofu processing and tested in the home-scale tofu processing industry in the Semanan area, West Jakarta. The test results on the pH level of the waste, green mussel shells have been able to reduce the degree of acidity by up to 52%. Visually, turbidity and foam in the liquid waste from tofu processing are reduced. It is undeniable that filter media from green mussel shells can be used as an alternative filter material for liquid waste. This research has succeeded in reducing the impact of liquid waste pollution from tofu processing]]>

<![CDATA[Abstract. We develop a smart digital advertisement board system which allows the system to display advertisements based on the majority of age and gender classifications of the consumers. The system captures the faces of the crowd and the face recognition techniques used to classify the majority gender and age of the crowd and then shows appropriate advertisement from the database to the advertisement board. A DNN model that is built, trained, and validated is used to recognize and predict the age and gender of the visible faces through image input or webcam using face photo dataset known as audience dataset. Several testing and analysis have been done onto the system in order to demonstrate the effectiveness and reliability of the system in displaying suitable advertisement for the public. The system can get gender accuracy of 77.82% and 86% for female and male respectively. And 68.78% accuracy for age recognition. The recognition speed is less than 1.3 second for up to 9 faces in an input image.]]>
