<![CDATA[Currently, using natural fibers as composite reinforcement is a new pattern in material technology. Natural fiber-reinforced composite materials have sustainable potential in the industrial field because the natural fibers used significantly impact the composite's mechanical properties. However, the chemical content of natural fibers can affect the mechanical properties of the composite. Therefore, chemical treatment of fibers that will be used as composite reinforcement must be done to produce mechanical properties such as optimal impact strength. This research aims to see the effect of treatment time on citronella fibers and the type of treatment solution on the resulting impact strength. The method used in this research is a 2k factorial design. In this study, the impact test used the ISO 179-01 standard reference with the treatment of citronella fiber soaked using liquid smoke solution and fiber boiling using turmeric solution, and the length of the treatment process was 1 hour and 3 hours. The results showed that the interaction between the type of solution and the length of treatment time affected the impact strength.]]>

<![CDATA[Polluted tin washing wastewater can be neutralized using activated charcoal made from clam shells. Clam shells are one of the materials that have a very high CaCO3 (calcium carbonate) content and are very effective in being used as an active charcoal material. Shells that have gone through the combustion process will become CaO (Calcium Oxide) and can become alkaline when dissolved with H2O (water) will produce Ca(OH)2 (Calcium Hydroxide) which is alkaline so that it can increase the pH quality of tin washing wastewater. Activated charcoal which has more open pores due to the combustion process, makes it stronger to absorb acid levels in tin washing wastewater in Air Nyatoh Village. In this study using the Taguchi method with Nominal is Best characteristics, the desired pH is pH 7.5 using matrix L9 (34) with factors namely Activated Charcoal Weight, Activated Charcoal Size, and Settling Time. Activated charcoal in this study uses Melo - Melo Clam Shells (Bailer Shell) that have been activated. After conducting the testing process, water that was originally at pH 4.0 experienced an increase to an average pH of 7.41. This is closer than the desired pH. Based on the calculations in this study, the weight of activated charcoal has an F Value of 23.56 and the size of activated charcoal has a value of 24.28. Both factors are the same - both have an influence on the increase in pH, while the deposition time has a value of 7.0 and has no effect on the increase in pH when measured against the F Table 5%, namely with a value of 19.00.]]>

<![CDATA[The manufacturing industry now demands machining processes that are not only precise but also highly efficient. Computer Numerical Control (CNC) machines such as CNC milling have emerged as the answer to these challenges by enabling high-precision mass production. The State Polytechnic of Manufacturing in Bangka Belitung has an aging CNC Milling Machine Lagun MC-750, which has been in use since the establishment of the campus several years ago. The research is focused on metrological testing of circular motion on the CNC Milling machine in the Mechanical Workshop of Polmanbabel. The analytical method involves experimental studies encompassing machining processes, data collection of the results, and data analysis. The machining process is carried out using the CNC Milling Machine Lagun MC-750 with specific parameters such as cutting depth, cutting speed, and feed motion. The test specimens are made of S45C steel with dimensions Ø31.6 x 50 mm. The analysis of 12 specimens revealed a value of 146 μm for clockwise feed motion (G02) and 174 μm for counterclockwise feed motion (G03) for the other 12 specimens. These results fall within the tolerance grade IT 10. This indicates that the machine is suitable for processing workpieces within standard tolerances, as IT 10 is commonly used in general machining for interchangeable parts that can also be classified as highly precise work.]]>

<![CDATA[One important factor in achieving good quality value for a product in the machining process is to look at the level of roughness produced in the machining process. This research aims to determine the effect of feed depth and cutting speed on surface roughness. The process variables used in this research are feeding depth (mm) and cutting speed (m/min). Each variable has 3 levels, namely feeding depth of 0.5, 0.6 and 0.7 mm. Cutting speed 65, 70 and 75 m/min. In this research method, researchers used the full factorial method. The material used in this research is SKD 11 steel. The conclusion obtained from the research is that the minimum surface roughness is at a cutting depth of 0.6 mm with a cutting speed of 65 m/minute, with the average surface roughness value obtained being 0.883 (µm ). The maximum surface roughness is at a feed depth of 0.6 mm with a cutting speed of 70 m/minute with an average surface roughness value of 1.254 (µm).]]>

<![CDATA[Technology is evolving, and so is the manufacturing process in the industrial world. One technology that is widely used in making products with ideal dimensions is 3D printing. One of the widely used 3D printing methods is Fused Deposition Modeling (FDM). The working principle of FDM is to extrude thermoplastic filaments through a heated nozzle and print layer by layer. With the development of technology, the filaments used in 3D printing also vary. Carbon Fyber is one of the most popular materials in the industry due to its strength and durability. This study was conducted to find the optimal combination of nozzle temperature, layer height, and print speed parameters for dimensional accuracy and surface roughness on Carbon Fyber filament products. The process parameters used in this study are nozzle temperature, layer height, and print speed. The nozzle temperatures used were 195°C, 210°C, and 225°C. The layer height variations used were 0.15mm, 0.20mm, and 0.25mm. Meanwhile, the print speed is 70%, 85%, and 100%. The parameters will be arranged based on the orthogonal matrix L27(33) with interactions between parameters. Response parameters used are surface roughness and dimensional accuracy. From this study it can be concluded that the parameter that has the most influence on both responses is layer height. Parameter optimization for Carbon Fyber filament products can use the parameters of nozzle temperature 195°C, layer height 0.20mm, and print speed 85%.]]>

<![CDATA[Public Street Lighting (LPJU) is a source of lighting that helps road users when crossing the road at night. But there are still many LPJUs that light up during the day in the absence of a control system. Therefore, this study will discuss the LPJU automatic monitoring and control system using LoRa as a remote communication device. The methodology on this system uses LDR sensors as input and is processed by esp32 devkit v1 with lora communication as data transmission, and the monitoring system uses the website display on localhost phpmyadmin. The results of LoRa communication testing in LOS conditions with a distance of 100 m to 2000 m were successfully sent and received well from LPJU to a laptop even though there was a delay in data reception, while in Non-LOS conditions LoRa communication was less than optimal because there were delays and obstructions when receiving data with a distance of 1 meter to 30 meters. LPJU can be activated and disabled automatically using LDR as an automatic salkar contact, and monitoring results can be displayed on a website page with an internet connection.]]>

<![CDATA[Indonesia's natural products are very rich, including containing several types of animals, one of which is a clam that belongs to one type of shellfish. Mussel shells contain 39.55% calcium carbonate (CaCO3). The presence of calcium carbonate in the shell makes it possible to use it as a source of catalyst in the carburization process. Carburization adds carbon to the steel when heated to austenitic temperatures, causing the carbon to diffuse onto the steel surface. Low carbon steels with a carbon content of less than 0.3% are usually used in this process. Among the low-carbon steels widely used in industry, there is St 42 Steel, which has exceptional strength. Coconut shell charcoal is used as a catalyst. Coconut shell charcoal is one of the active carbon materials. Activated charcoal from coconut shell has low ash content, high reactivity and good solubility in water. The research method used is experimental. Steel ST 42 is used as the material. At the same time, the carburizing medium is activated carbon powder from coconut shell and shellfish powder by 10%, 20% and 30%, respectively, when heated for 3.6 and 9 hours.]]>
