Abstract

Fires often become disasters that can cause significant losses, both material and human lives. Fires can occur anywhere, including buildings, homes, and industries. During a fire, the risk of death or serious injury is also very high for people trapped inside a room, due to limited access to exit from the room where the fire occurs. Security is one of the most important aspects of life; everyone needs greater safety assurance regarding their home. In this research, the author employs system development and simulation methods, which allow researchers to reproduce complex environments and test system performance under various conditions without building actual physical infrastructure. Researchers have an idea to create a model and simulation of an automatic fire extinguisher and a security system based on IoT and cloud computing using Cisco Packet Tracer. The use of Cisco Packet Tracer as a simulator allows for the creation of IoT-based network simulation models to analyze the results of the simulations on the developed system, ensuring that the simulation results are accurate. The automatic fire extinguisher and security system simulation model yields positive results. When a fire is detected, the sprinkler system, alarm, and LCD provide information indicating a fire, while exit access such as doors and windows yield good simulation results. Additionally, the simulations for security systems for entrance security and rooms containing valuable items produce favorable simulation outcomes.

Abstract

The independent curriculum requires teachers to carry out an initial assessment to determine the appropriate form of learning according to students' learning styles. This is the basis for determining appropriate learning methods for teachers to apply to each student. It is difficult to detect student learning styles at the beginning of learning. Identifying student learning styles is an important indicator of successful learning in the independent curriculum. The application of the CF method is appropriate to the problem of determining student learning styles because the criteria values ​​used in determining learning styles are mostly certain and uncertain. The results of this research are to provide recommendations to teachers whether the stimulation given to students based on learning styles is appropriate and to monitor students' cognitive development, it will be easier for teachers to organize learning according to students' learning needs by paying attention to students' learning styles. The system will produce a report sheet on the diagnosis of the percentage of children's learning styles in what areas and the stimulation that teachers can provide based on the type of learning style.

Abstract

A woman's fertile period is a menstrual cycle in women that occurs once a month. The average fertile period lasts between days 8-19 after the first menstrual period ends. During this fertile period, women will release mature egg cells from the ovaries to the uterus or the so-called ovulation period. There are several menstrual cycles in women, namely the follicular fake menstrual cycle (pre-ovulation) and the luteal phase. If the menstrual period in women is smooth, it is said that it is impossible to have a disease, but in fact there are still diseases in women who have experienced a menstrual period who must get a doctor's treatment as soon as possible.Edward clinic is one of the gynecology clinics that currently serves a variety of health care in pregnant women and complaints in certain areas of women, as well as problems with female fertility. With the development of increasingly sophisticated technology, Edward clinic must be able to follow the development of existing systems in order to make it easier for users to find more complete information by processing patient data and other information. Therefore, the authors want to design an application to assist users in providing services to patients in obtaining more efficient information about the problem of women's fertile period disease, by designing and building a system that will be used in the process to diagnose women's fertile period disease based on symptoms felt by patients using Bayes ' Theorem method, in order to facilitate and shorten the time patients in consultation or further examination. From the results of the study obtained the certainty value of the combination of bayes ' theorem that patients are likely to experience egg follicle disease in women's fertile period with a percentage of 69.50%.

Abstract

The health and beautiful appearance of pets is important because treating these diseases requires more money. If the pet is infected with a disease that can be transmitted, then as the owner you have to do something to find out the type of disease and treatment, one of which is cats. However, many keepers still do not know the symptoms of diseases suffered by cats. So the treatment that should have been carried out at the beginning is delayed and the cat is no longer healthy because it is already suffering from an illness. The lack of veterinarians is also one of the factors causing delays in treatment for cats. For this reason, we need a system that can store knowledge about the symptoms and treatment process of the disease experienced by the cat. Expert system is a system that adopts human knowledge into a computer so that the computer is able to solve problems the way an expert works. Meanwhile, the Certainty Factor Method is a method that defines a measure of certainty regarding facts or rules to describe an expert's confidence in the problem being faced. Based on the results of the trials carried out, it was found that the highest confidence value was in the symptoms of Ringworm disease with a confidence value of 91%.

Abstract

The free lunch program is a goverment initiative aimed at addressing the issue of stunting in Indonesia. This program focuses on toddlers, school-age children and pregnant women. Various opinions have emerged from the public regarding this initiative, especially through sosial media platform X (Twitter) and news portals. In this research, sentiment analysis was conducted to understand public responses to the program, whether they are positive, neutral or negative. To evaluate the accuracy of the sentiment analysis perfomed, a deep learning approach was applied using the Long Short-Term Memory (LSTM) algorithm. The results show that public sentiment varies responses, on social media X tend to be negative, while those on news portals tend to be positive toward the free lunch program in Indonesia. Through LSTM-based testing, sentiment analysis on tweet data achieved an accuracy of 88.6%, with a precision of 84.6%, recall of 88.6% and an F1-Score of 86.3%. Meanwhile, sentiment analysis on news portal data reached an accuracy of 89%, with a precision of 81.7%, recall of 89% and an F1-Score of 85.1%.

Abstract

Increasingly tight business competition encourages Micro, Small, and Medium Enterprises (MSMEs) to have the right strategy in developing their business, one of which is through selecting strategic branch locations. This study aims to design and build a decision support system for MSME branch placement based on SWOT analysis combined with the Promethee method. The case study was conducted on the Cak Kotes MSME, which operates in the beverage sector and has three branches in Binjai City. SWOT analysis was used to identify internal factors (strengths and weaknesses) and external factors (opportunities and threats) relevant in location selection. The Promethee method was applied to weight and rank alternative locations objectively and systematically. This web-based system was built using the CodeIgniter framework, the PHP 5.3.7 programming language, and the MySQL database. The results of this system are expected to assist MSME owners in determining the most appropriate branch location for the target market and increase the efficiency and effectiveness of business decision-making.

Abstract

Kriptografi merupakan ilmu dan seni untuk menjaga keamanan pesan ketika pesan dikirim dari suatu tempat ke tempat lain. Kriptografi digunakan agar kerahasiaan pesan tersebut dapat terjaga, sehingga tidak diketahui oleh orang lain. Kriptografi ini muncul atas dasar keamanan dari suatu bentuk informasi-informasi penting yang bersifat rahasia. Steganografi merupakan cara menyisipkan pesan ke dalam media tertentu misalnya gambar, audio, video, dan lainnya. Cara ini terbukti efektif untuk mengamankan pesan teks dengan cara disisipkan pada file gambar, dan pesan tersebut tidak akan diketahui oleh pengguna lain jika didalam gambar yang sudah disisipkan pesan terdapat suatu pesan rahasia. Dan dalam penelitian ini dilakukan proses enkripsi dengan algoritma One Time Pad (OTP) XOR untuk mengubah pesan teks menjadi chiper atau pesan acak dalam bentuk bilangan biner. Kemudian chiper tersebut disisipkan ke dalam file gambar melalui bit-bit paling tidak berarti dengan metode Least Significant Bit (LSB).

Abstract

Pengamanan pesan diperlukan dalam rangka untuk mencegah pesan yang didistribusikan dapat dibuka oleh pihak lain yang tidak berkepentingan di mana pada akhirnya dapat mengancam kemanan dan kenyamanan dari si pengirim maupun penerima pesan tersebut. Untuk mengamankan pesan tersebut dalam dilakukan penerapan ilmu kriptografi yang bertujuan untuk mengubah pesan asli (plaintext) menjadi pesan terenkripsi (ciphertext), di mana untuk membukapesan tersebut memerlukan kunci.Algoritma One Time Paddikenal dengan nama holygrail algorithm dikarenakan algoritma kriptografi One Time Pad adalah algoritma yang sempurna yang tidak bisa dipecahkanbiarpun begitu algoritma One Time Pad memiliki kelemahan dalam menjaga kerahasiaan atau keamanan kunci sehingga harus diberikan pengamanan pada kunci agar kunci dari OTP itu selama pengiriman terjaga kerahasiaanya. Sedangkan pada algoritma asimetri atau kunci publik ada algoritma Elgamal yang juga mempunyai keamanan yang tinggi karena kompleksitas algoritmanya.Dengan disuper enkripsikannya algoritma one time pad dan ElGamal tersebutdapat meningkatkan keamanan pada pesan dan juga dapat menjaga kerahasiaan atau keamanan kunci dari one time pad selama proses pengiriman pesan dan kunci
