Abstract

The need for information through a monitoring system on BTS tower equipment is very necessary, including monitoring lightning strike protection. To find out whether there is a strike on the BTS, usually, technicians have to come to the BTS location to see the impact of the strike in the form of damage to the arrester, or other damage and even seek information from residents around the BTS location. The location of the BTS location is far from the head office, of course this is not effective.This research is the development of a counter lighting system designed to monitor and detect lightning strikes from a distance. By using Arduino Uno, ethernet shield, current sensor and android smart phone. The information displayed on the android smart phone is the location of the BTS tower, the time and magnitude of the strike current. The lighting protection monitoring tool based on android operation using the PZEM-004T module is a system designed and utilized to read the presence of lightning strikes which include the current flowing in the BTS tower grounding system.The test results show that the lighting protection monitoring tool using the PZEM-004T module can measure and display the current value and when a strike occurs, in real time and stored in the database. Based on the test results, it can be concluded that the results of the design of the lighting protection monitoring tool have a deviation (error) of 9,64% and a current of 12,5%.

Abstract

The Semarang City Government is currently developing tourism potential in the Semarang City area. However, the number of tourist attractions in the city of Semarang makes tourists who come to the city of Semarang to be confused to visit the tourist attractions that will be visited. In this study the authors provide solutions for grouping based on the type of tour such as religious tourism, environmental tourism, water tourism, nature tourism and education tourism. The use of the Dijkstra algorithm will be used to help find solutions to visit these tourist attractions. In this system the Google Maps API will be used to display spatial data to indicate the route to be passed. System design to create a Geographic Information System using the Unified Modeling Language (UML). Tourists later use this application by entering the initial location information and the location you want to get to get the route. Based on testing that has been done the system is able to display information on the route it travels will be bypassed by tourists. The results of research and field studies that have been carried out, can be concluded from the user acceptance testing in terms of usefulness of 89.5%, in terms of use of 89.3%, in terms of appearance of 89.5%, and in terms of accuracy of 87.6%, that is strongly agree.

Abstract

Abstrack -  PT. Pijar Sukma is a furniture industry company, located in Jepara, Central Java. PT. Pijar Sukma is having problems that customer order requests cannot be fulfilled according to production targets. So companies need tools that can measure performance. This research uses the performance prism method which involves stakeholders so that they can form the sides of the prism, namely satisfaction, contribution, strategy, process, and capability. From these methods used to compile key performance indicators (KPIs), 30 KPIs were produced based on satisfaction and contributions in the design that had been prepared, there were 10 strategic KPIs, 10 process KPIs, and 10 capability KPIs that were weighted through the analytical hierarchy process (AHP) method, then scored using the analytical hierarchy process (AHP) method. OMAX to provide an actual value with a score of 1-10 on each KPI and the traffic light system as a color assignment, namely green means very good / the target is maximally appropriate, yellow is quite good / the target has not reached the maximum, and red means bad / the target has not been maximized . The results of the processing and calculation show that the company's performance index value of 2.836 is categorized as red with an actual value of 3.00, meaning the company has achieved the performance measurement plan but has not reached the set target so that the company can maintain good performance and make changes to poor performance by improving performance in red. Key words: Key Performance Indicators (KPI), Performance Prism, Analytical Hierarchy Process (AHP), Objective Matrix (OMAX), and Traffic Light System.

Abstract

E-Commerce has had a major impact on social and economic growth in society. However, E-Commerce system is not always profitable for UMKM actors themselves, there are several factors that cause UMKM quality assessments to decline from tight competitiveness. Many consumers consider buying products from the many existing E-Commerce systems. For this reason, this goal is to implement a decision support system in determining E-Commerce using the TOPSIS method with AHP method. Of course, in implementing a decision support system, it is necessary to have assessment criteria and a number of alternatives that will be used as a reference to determine E-Commerce for UMKM by calculating the TOPSIS method which will produce the final result of the value of each E-Commerce in the form of ranking. From research conducted on 38 UMKM in Tuban Regency, the results of E-Commerce Shopee are 60.5%, Tokopedia 15.8%, Blibli 10.5%, Lazada 7.9% and Bukalapak 5.3%. The data will be grouped from each alternative to find the average value based on predetermined criteria and calculated using the TOPSIS method AHP method, it can be concluded that the E-Commerce that is widely used by UMKM in the Tuban Regency area is Shopee > Tokopedia > Bukalapak > Lazada > Blibli. while with AHP resulted in the order of Tokopedia > Shopee > Bukalapak > Blibli > Lazada.

Abstract

Water is often taken with the help of a pump to remove water from the well to be filled into the reservoir.However, often during the dry season, many pumping machines are damaged because the pump is on but thewater in the well (source) is empty and no one knows it, so the pump engine does not turn off, therefore it cancause the pump to fail. be damaged. This study designed a system that can monitor the flow of water using theBlynk application. Monitoring is carried out using a smartphone with a NodeMCU ESP8266 microcontrollerconnected to the internet network. The sensor used is a water flow sensor to detect the flow of water. The Blynkapplication is used by the user as a data display for the NodeMCU ESP8266 microcontroller which is integratedinto the internet network. The results of the research water flow sensor has worked well on the water pump.After testing the distance, the distance is detected indefinitely provided that the microcontroller and the blynkapplication are connected to the internet network, and do not experience internet network trouble.

Abstract

Machines and equipment or work processes that make noise. Evaluation of noise intensity is carried out by making a noise map that describes the noise distribution pattern from 278 measurement points and then processed with surfer software, which then becomes basic information to protect workers from the risk of hearing loss. After measuring and analyzing the data, the noise level ranged from the lowest of 41.0 dBA, to the highest of 101.9 dBA. From the noise map, it can be seen that the main sources of noise are in the workshop area, corn intake & dryer area, generator area & bagging off area. Noise control efforts have been carried out by engineering controls, administrative controls in the form of work rotation, Standard Operating Procedures, training, safety signs and the use of ear protective equipment for workers in the form of earplugs and earmuffs.
