Abstract

Akses energi masih terbatas pada beberapa wilayah dengan kriteria terpencil, tertinggal, terluar (3T). Selain itu keterbatasan juga masih terjadi pada daerah yang dianggap kurang ekonomis bila dibangun sistem atau jaringan listrik. Oleh karena itu, perlu adanya suatu implementasi teknologi panel surya yang mampu meingkatkan perekonomian masyarakat pada daerah yang memiliki keterbatasan tersebut. Tujuan dari penelitian ini ada tiga. Pertama, merancang sebuah purwarupa kios minuman berkonsep container booth yang kebutuhan energinya dipenuhi menggunakan panel surya. Kedua, menganalisis perbandingan konsumsi energi antara sistem listrik arus searah (DC) dan listrik arus bolak-balik (AC) bila digunakan untuk memenuhi kebutuhan container booth. Ketiga, menganalisis potensi pengurangan emisi karbon melalui penggunaan container booth bertenaga surya. Penelitian ini dilaksanakan dengan melakukan analisis kebutuhan energi awal melalui survei pada pengguna container booth yang telah ada. Selanjutnya, dilakukan perancangan sistem dan menguji energi yang dihasilkan oleh panel surya serta energi yang dikonsumsi untuk pengolahan minuman. Dari data pengujian pada masing-masing sistem (DC dan AC) dianalisis total energi yang dihasilkan dan potensi pengurangan emisinya. Sistem AC memiliki efisiensi sebesar 21,11% sedangkan sistem DC memiliki efisiensi sebesar 19,08%. Dari sisi penggunaan baterainya selama 1 hari pemakaian, sistem AC akan mengurangi 12,03% baterai sedangkan sistem DC sebesar 14,34%. Hasil analisis menunjukkan bahwa kios minuman bertenaga surya ini mampu memenuhi kebutuhan energi operasional selama 2 hari dan mampu mengurangi emisi setara dengan 34,82 sampai 58,84 kg CO2. Konsep ini diharapkan dapat menjadi alternatif bagi masyarakat.

Abstract

The development of information and communication technology, especially in this digital era, demands communication takes place quickly and the management of network connectivity efficiently and effectively. In line with this, PT Indonesia Comnets Plus have built the Metro Ethernet network which is an ethernet network technology implemented in a metropolitan area (big cities). The company provides an internet network due to providing the best quality network is compulsory. Hence, we need a Metro Ethernet network monitoring system with the aim of being able to know the performance and problems efficiently and in real time. One of the open source based applications used for network monitoring is Zabbix. This study aims to create and test the performance of Raspberry Pi in the Metro Ethernet network monitoring system at PT Indonesia Comnets Plus with the case study of DISKOMINFO in Garut Regency using the Zabbix application. In monitoring, the SNMP (Simple Network Monitoring Protocol) protocol is needed which will send network problems in the form of triggers. Trigger will evaluate the data collected and represent the current state of the system. Trigger contains two statuses, "OK" and "PROBLEM", to determine the threshold for what is "acceptable" data. Therefore, if the incoming data exceeds an acceptable state, the trigger status changes to "PROBLEM", the trigger status is recalculated every time the Zabbix server receives a new value. Zabbix server will send trigger status to electronic mail (e-mail) and Telegram application as notification for network administrators.

Abstract

Home security is a mandatory requirement for every homeowner. With home security, homeowners will always feel safe leaving the house for a long time. In this final project, the author made a smart door with its main components are the HC-SR04 ultrasonic sensor and web camera. The function of the ultrasonic sensor and webcam is to detect a movement in the area around the access of people. In this system, not only can it detect movement, but also send notifications in the form of text and videos through the Telegram application so that homeowners can find out if someone tries to enter the house even though the owner of the house is away from his house. The author also adds dual security in the form of a remote control system, where when the homeowner knows of theft, the homeowner simply sends a "close" message through the Telegram application, so the door automatically locks and keeps the thief for a while until the homeowner arrives at location. This remote control system can also be used when the homeowner forgets to lock the door so that when the owner of the house is away from home, he simply controls the door through the telegram application.

Abstract

Abstract – A server room is a room used to store applications, data and network devices such as routers. The server room is the data center of a company or institution in which there are applications and databases that store all important and valuable information for the company or institution concerned, therefore the server room must always be in good temperature conditions because the devices work for 24 hours no stopping. If there is a significant increase in temperature, it can cause system performance to be disrupted or hardware damage occurs. The cooler in the server room is not optimal because the cooler is often constrained by frequent power outages. From these problems, a solution is needed to be able to monitor the system remotely so that changes in room temperature can be seen in real time. The Internet of Things (IoT) is the solution to this problem, by using LoRa, which then sends the data to the Telegram application that has been installed on the smartphone so that real-time temperature changes can be obtained

Abstract

Energy access is still limited to several areas with the criteria of being remote, underdeveloped, outermost (3T). In addition, limitations still occur in areas considered less economical if an electrical system or network is built. Therefore, there is a need to implement solar panel technology that can improve the economy of the people in areas with these limitations. The objectives of this study are threefold. First, to design a beverage kiosk with a container booth concept where its energy needs are met using solar panels. Second, to analyze the energy con-sumption ratio between direct current (DC) and alternating current (AC) electricity systems when used to meet the needs of the container booth. Third, to analyze the potential for reducing carbon emissions through the use of solar-powered container booths. This research was conducted by analyzing the initial energy requirements through a survey on existing container booth users. The system design is carried out and tests the energy produced by solar panels and the energy consumed for beverage processing. The total energy produced and the potentials for emission reduction were analyzed from each system's test data (DC and AC). The AC system has an efficiency of 21.11%, while the DC system has 19.08%. In terms of battery usage for one day of use, the AC system will reduce 12.03% of the battery while the DC system is 14.34%. The analysis shows that this solar-powered beverage kiosk can meet operational energy needs for two days and reduce emissions equivalent to 34.82 to 58.84 kg of CO2. This concept is expected to be an alternative for society.

Abstract

Data is increasingly recognized as a valuable asset for generating new insights and information. Given the importance of data, businesses must always look for ways to get more value from data generated from sales transactions. In data mining, association rule mining is a good standard technique and is widely used to find interesting relationships in databases. Association rule is closely related to market basket analysis to find items that often appear together in one transaction. This study proposes the frequent pattern growth (FP-Growth) algorithm in finding association rules on sales transaction data. Our methodology includes dataset preparation for modeling, evaluation of model performance, and subsequent integration into a web-based platform. We conducted a comparative analysis of the FP-Growth algorithm against the Apriori algorithm, finding that FP-Growth outperformed Apriori in efficiency. Using the same dataset and constraint level, both algorithms produce the same number of frequent itemsets. However, in terms of computation time, FP-Growth excels by taking 2.89 seconds while Apriori takes 5.29 seconds. We integrated trained FP-Growth algorithm into a web-based dashboard application using the streamlit framework. This system is anticipated to simplify the process for businesses to identify customer purchasing patterns and improve sales.
