Abstract

Motorcycles are two-wheeled vehicles that are very common and widely used in Indonesia. At the same time, the criminal rate of motorcycle thieving also has the possibility to increase. The standard security system that motorcycles have is still ineffective. One solution to secure motorcycle from theft is adding a security system. The security system used in this research is a tracking system using a Quectel L80-R GPS connected to an ESP8266 NodeMCU which then installed on a motorcycle. The GPS then integrates with the Telegram application. Users can request the location of the motorcycle by pressing the button on the Chatbot that was previously created. Then the GPS will send a link containing the coordinates of the motorcycle location which can be opened via Google Maps. In this research, the location obtained from the GPS response is quite accurate with an average error distance of 3,06 meters in outdoor tests and 3,51 meters in indoor tests with each 30 trials in 3 different places. Thus, the tracking system using Quectel L80-R GPS can be used properly as a motorcycle security system and has been integrated with the Telegram application.

Abstract

Insert separators are part of the Open-end spinning machine that plays an important role in the process of feeding the fiber to the rotor. The function of the insert separators is as a conductor of drawing sliver which has been combed into individual fibers by adjusting the angle point of the insert separators. Damage to insert separators affects the number of slub yarns in the process of making Open-end spinning yarn. Consumption of using the separator insert continuously can make damage (eroded). The damage occurred during 20 days (four weeks) of 35.25 times of observation. The number of damaged separator inserts requires a repair whether the repair is done by patching, but in fact repair by patching is not an effective way, because the age of the patch only lasts approximately 1 week. Therefore, patch repair is not carried out, the best effort is to replace the separator insert.

Abstract

The Community Health Center (Puskemas) is the foremost and closest place to provide health services to the community. With the BPJS and complete facilities, the Puskesmas is now almost the favorite of the people to get health-related consultation and treatment. So this study tries to make an analysis of puskesmas services and evaluate the layout and queues in the puskesmas using Promodel simulations. The simulation is used because of the fluctuating number of patients who come every day, so that with the simulation the process of estimating patient arrivals can be carried out using statistical distribution estimates. The results of this study indicate the need for a new layout change, where with this new layout the patient's time in the system can be reduced and the need for adding doctors to 2 to 3 people to cut the number of queues that have accumulated waiting to be examined by a doctor. If the point of adding doctors cannot be met, then the puskesmas can provide adequate waiting room facilities for patients who will be examined by a doctor. The ideal number of waiting room seats for patients waiting to be examined by a doctor is 38 seats.

Abstract

Environmental problems such as erosion, flooding, are mainly caused by human activities itself. Due to main environmental problems mainly came or originated from man, the solutions or prevention effort to repair the environment, must involve human factors in its planning. In Indonesia in general, including in Bendungan Village, limited insight, lack of skills, poor health, and a low work ethic are all internal factors that cause environmental problems. Furthermore, the lack of knowledge about the environment is one of the causes of the emergence of environmentally destructive behavior that is carried out unconsciously. One of the problems in this village is garbage, people throw garbage into drains and empty land because they are not aware of the consequences of their actions. One solution that exists to solve environmental problems by involving human factors in it is through capacity building, one of which is through a sustainability education and incentive given by the West java Government. Through this concept, citizens are given education about the impact of their previous behavior, one of them is the behavior of littering. The program also provides economic value to waste so that there is an incentive to maintain the condition or waste managing waste in their village. This research used Mixed Methods approach (quantitative and qualitative) and use secondary data review, direct observation and semi semi-structured interviewing to collect the data. This research found that the main factor for the success of this program is the people who willing to be open concerning the program and its concepts, thus becoming aware about their environmental problems, they willing to work for the benefit of their village. In this village the push factor are economic and re-education aspects that move the people to save their environment. The economic benefit from garbage bank also have helped this program. The obstacles to the program in this village are the lack of facilities that they have, and for cadres to teach people about the environment, the lack of the government to provide formal education for the people and the last obstacle of this program is the economic factor, low amount of sellable garbage such as PET and cans have become major obstacle in promoting garbage bank.

Abstract

Belt conveyor is a material transfer machine that is generally used in the industrial world to transport semi-finished production materials and products from one part to another. In making a conveyor belt, the main component is needed, namely the frame. The frame is a construction that functions as a place where the components become a unit on a machine. In this research, a simulation test will be carried out to determine the strength of the construction and the material used by the framework for component loading by providing maximum carrying capacity for variable loading. The loading given is 100kg, 200kg, 300kg, 400kg and 500kg. This test simulation uses the Ansys Workbench 2020 R2 software with the finite element analysis (FEA) method. Analysis of strength testing uses a frame model measuring 4070 mm x l500 mm x 2440 mm as the main frame which is then simulated with maximum loading variations ranging from 100 – 500kg. The analysis results from testing the strength of the construction of the conveyor belt frame against the loading variable, obtained a safety factor of 100kg = 3.70; 200kg = 3.01; 300kg = 2.67; 400kg = 2.41; 500kg = 2.16. The minimum safe limit for dynamic loads is 2 according to Dobrovolsky's "machine element" book, thus the maximum loading tolerance for the conveyor belt frame may not be more than 500 kg.

Abstract

Batik wastewater produced in the batik industry in Bayat, Klaten Regency, contains chromium and phenol, which pass the wastewater quality standard. This study aimed to evaluate the ability of tuff breccia from the study area to reduce chromium and phenol concentration in batik wastewater. Mineralogical and chemical characterization was conducted to investigate tuff breccia's mineralogical and chemical composition. A batch and regeneration test was conducted to investigate tuff breccia's ability to reduce the chromium and phenol concentration in the batik wastewater. The characterization of tuff breccia indicates that the tuff breccia consists of fragments, minerals (quartz, plagioclase), and clay minerals (smectite and illite). The batch test results show that the grain size of tuff breccia and the pH value significantly influence the ability of tuff breccia to reduce the chromium and phenol concentration in batik wastewater. The regeneration test showed that the tuff breccia would decrease the capability by up to 30 percent after five times of use.
