Abstract

In general, in our daily lives, without realizing it, we encounter electrical disturbances that we cannot see by eye, namely among them the voltage drop or the presence of flicker, which is caused by the large amount of work using dynamic loads, which tend to be dominant using dynamos. ie now we need to know the planning and design with a power of 150 KVA. and of course with frequent power outages, we must have prevention with protection using a UPS with a capacity of 8 KVA for residential areas that are temporary or can be called temporary power source voltage. So that we can carry out urgent or sudden activities for rescue actions so that our work is not lost, so there is still time to back up data.

Abstract

The Regulation of Minister of Energy and Mineral Resources Number 02 Year 2019 concerning Minimum Free Distance and Free Space of High Voltage Air Channel, Extra High Voltage Air Channel, and High Voltage Air Channel of Direct Current for Electrical Power Distribution has specific regulation related to free distances toward High Voltage Air Channel and Extra High Voltage Air. Voltage 150kV has minimum free distance 5m in which stand inspection below transmission channel path has encountered several objects disrupting electricity distribution. For this reason, the researcher developed an application for measuring distance by lidar sensor and android smartphone supported with gyroscope features. All of them were then processed through trigonometry formula for obtaining the measurement value. The results of measurement test on tree height (C) within maximum distance 12 meters gained difference span:  30 degrees from 0.02 to 2.99m, 45 degrees from 0.007 to 10.25, and 60 degrees from 2.29 to 15.33m. Meanwhile, distance measurement (B) from user to tree within maximum distance 12 meters had difference span: 30 degrees from 0.17 to 4.97m, 45 degrees from 0.13 to 9.85m, 60 degree from 1.31 to 8.99m, and thus the span error was 0.381-0.803.

Abstract

This research discusses the design of a lux meter based on the TSL2561 sensor. The testing was conducted by comparing the measurement result of lux using the designed lux meter device with a reference device. The testing data was obtained from three different smartphones over a period of three minutes, but only 10 data points were presented. The test results revealed differences  between the readings of the TSL2561 sensor and the reference device for each smartphone. These difference were attributed to the non-propotional positioning of the flashlight when directed into the device’s box, resulting in suboptional light reception by the sensor. The conclusion of this study is that the lux meter device can function effectively when the flashlight’s positioning and stability are properly maintained. The accuracy level was found to be 71% between the sensor data and reference data for smartphone A, and 99% for smartphone B

Abstract

The development of information technology, especially computer networks, allows the exchange of information that is easy, fast, and increasingly complex. Computer network security must be considered in order to maintain the validity and integrity of data and information residing in the computer network. The problem that arises in the CCTV control center is that there is no security against the detection of attacks that can occur at any time, for example a ping flood attack. Ping flood itself can be interpreted as a simple denial of service attack in which the attacker floods the victim with "echo request" (ping) packets in the ICMP protocol. To overcome the problems faced by the Lubuklinggau City Police control center in carrying out CCTV server security, the solution offered is to build an Intrusion Detection Server (IDS). IDS itself can read incoming and outgoing data packets automatically which will provide a report (log) to the network administrator. One of the most widely used IDS tools is Snort. Snort has several advantages compared to other IDS software, including source code that is small in size, compatible with many operating systems, fast in detecting network attacks, easy to configure and is open source.

Abstract

Libraries are not only places where books are stored, but are also centers of intellectual activity that play a key role in enlivening the spirit of learning and the discovery of knowledge. Through a variety of systematically arranged collections and diverse services, libraries are able to facilitate access to information for all levels of society. Apart from that, the library is also a place to share and exchange ideas, gather a learning community, and facilitate in-depth discussions and reflection.Thus, libraries and librarians are not only part of the educational infrastructure, but are also important assets in strengthening the foundations of knowledge and creativity that are the basis for sustainable development. There is a possibility that every week, the borrower borrows books from the library, so that there is repetition of the books borrowed, in repeating or borrowing the same book from one book to another, and can obtain useful information for the borrower. Next, choosing which books are suitable takes the form of book recommendations that are often related to each other according to the borrower's interests. To solve this problem, the Apriori Algorithm method is a suitable algorithm because it is one of the algorithms that carries out the searchfrequent itemset using the Association Rule technique. Association Rule what is meant is done through a counting mechanism support and confidence of an item relationship. An association rule is said to be interesting if the support value is greater than the minimum support and valueconfidence is greater than the minimum confidence. This a priori algorithm will be suitable to be applied if there are several item relationships that want to be analyzed and can be applied in the library field

Abstract

A hotel is a type of accommodation that is used as a provider of lodging, food and beverage services, as well as other services used by the general public. The hotel is managed on a commercial basis that meets the requirements stipulated in the Menparpostel's decision letter. Hotel revenue is a company activity that generates overall income which has two consequences, namely positive influence or income and profits and negative influence or expenses and losses. Hotel rooms are one of the main components produced by hotels as a determinant of the level of success of hotel operations. Forecasting hotel revenues can help entrepreneurs predict future revenues by using revenue data from the previous year. This analysis can help entrepreneurs determine strategies and policies to both increase their income and streamline existing costs. Therefore, researchers conducted a Decision Tree Algorithm analysis in predicting XYZ hotel revenue. The stages carried out in this research are data collection, initial data processing, further data processing (Forecasting), and comparative analysis. The results of this research, the DT algorithm produces an RMSE value of 45499674,430 with data split 81:19.

Abstract

Minyak yang dipakai berkali-kali akan mengalami penurunan mutu, yang terlihat dari perubahan warna, bau, dan tingkat kekeruhan. Penelitian ini merancang sebuah sistem pemantauan untuk kualitas minyak goreng dengan memanfaatkan tiga jenis sensor: gas TGS, sensor warna TCS3200, dan sensor kekeruhan berbasis LED-LDR. Data yang diperoleh dari sensor diolah menggunakan algoritma Gaussian Bell fuzzy dengan tiga input (gas, warna, dan kekeruhan) serta satu output (kualitas: baik, sedang, buruk). Uji coba dilakukan pada tiga merek minyak dengan lima jenis masakan (ayam, telur, tahu, tempe, dan terong). Hasilnya menunjukkan bahwa sistem ini dapat mengidentifikasi perubahan mutu minyak dengan efisien. Nilai hasil ditampilkan melalui layar LCD dan antarmuka pengguna grafis Python. Sistem ini bisa menjadi alternatif dalam menilai kualitas minyak goreng secara lebih obyektif.
