Abstract

Di masa pandemi COVID 19 ini banyak masyarakat yang melakukan WFH, sehingga mengakibatkan para masyarakat jenuh bahkan stress dikarenakan dirumah saja, di tambah lagi dengan pembatasan beraktivitas di luar ruangan, sehingga membuat masyarakat banyak yang ingin melakukan kegiatan lainnya, cara yang dapat dilakukan yaitu salah satunya memelihara hewan yang lucu dan juga menggemaskan yaitu sugar glider, sehingga menciptakan suasana baru didalam rumah yang bisa mengatasi kejenuhan masyarakat saat WFH, tetapi hewan peliharaan ini juga cenderung bisa terserang penyakit, penyakit yang sering menyerang sugar glider yaitu leptospirosis dan ada cara khusus untuk menangani nya, tidak hanya bisa menyerang hewan saja tetapi penyakit ini dapat juga menyerang manusia dan mengakibatkan kematian. Dari permasalahan ini maka untuk mempermudah Pengadopsi dalam mendeteksi penyakit pada hewan sugar glider, dirancang dan dibangun sebuah aplikasi sistem pakar dengan menggunakan Hybrid Metode Certainty Factor dan Teorema Bayes untuk mendiagnosa penyakit Leptospirosis dan memberikan solusi penanganan terhadap hewan sugar glider. Hasil dari penelitian ini adalah memudahkan para pengadopsi dalam mendiagnosa penyakit Leptospirosis yang menyerang hewan sugar glider. Adapun Sistem yang di buat berbasiskan web dengan mengimplementasikan Hybrid Metode Certainty Factor dan Teorema Bayes.Kata Kunci : Leptospirosis, Sistem Pakar, Teorema Bayes, Certainty Factor, Sugar Glider

Abstract

The village is a very important part in determining the success of development and is in direct contact with the community, especially in public services. Digitization can be interpreted as a process of storing all the properties and information of text, sound, images or multimedia in an electronic string of zeros and ones. The village is the most accurate data source for searching population data. The Village Information System makes it easier for Villages to compile digital data and information about the objective conditions of the Village, to prepare Village Development plans based on detailed and real data. Tadukan Raga is a village in the Sinembah sub-district of Tanjung Muda Hilir, Deli Serdang Regency, North Sumatra province, Indonesia. There are 5 hamlets, namely: Hamlet I Tungkusan, Hamlet II, Hamlet III Sei Basah, Hamlet IV Lottery, Hamlet V Kampung Dalam. From the results of the development of the Tadukan Raga Village Portal Information System which has been completed, it can be concluded that the Village portal system can assist the Village in disseminating Village activities and policies, so that appeals made by the Village can be easily accepted by the community and can be well documented every activity carried out by the village.

Abstract

This research focuses on the implementation of computer - based test exams in high schools which face the problem of not having differences in exam questions which results in weak security and validity of exam results. Therefore, a randomization method is needed to overcome this problem. The method used in random ization is linear congruent methods and multiplicative random number generator. There are 101 random questions, but only 40 questions are displayed for each student with a reference value of Xn and C, 2 will be added for each package of exam questions and to avoid question code=0, the calculation results will be added 1. The linear congruent methods (LCM) results achieve 100% accuracy, while the method The multiplicative random number generator (MRNG) only achieved 62.5% accuracy in randomizing the exam que stions. This accuracy comparison highlights the difference in the ability of the two methods to generate random permutations of test item packages. LCM randomization accuracy ensures that each student will receive a different set of test questions in a con sistent manner. However, the low accuracy of randomization using MRNG indicates a weakness in generating permutations of exam question packages. The results of this study show that the LCM method is better than the MRNG in conducting exams.

Abstract

Social media has become a space where many individuals express their opinions freely, including negative comments that may lead to hate speech. One group often targeted by such speech is Gojek drivers. This study aims to classify user comments on Facebook into two sentiment categories: positive and negative, with a primary focus on negative comments. The data was collected from public Facebook posts using the APIFY scraping tool. After the data was gathered, several preprocessing stages were carried out, including case folding, cleaning, tokenization, normalization, stopword removal, and stemming. The text data was then converted into numerical form using CountVectorizer. The classification algorithm used in this research is Naive Bayes with the MultinomialNB model, as the input data consists of word frequency. The results of the model evaluation show that this algorithm performs well in classifying negative comments, especially in identifying word patterns that commonly appear in hate speech directed toward Gojek drivers.

Abstract

The development of Internet of Things (IoT) technology has provided innovative solutions to improve security systems, including securing parcel boxes from theft. This study aimed to design and implement an IoT-based parcel box security system equipped with a vibration sensor as an anti-theft feature, automatic call notification using a GSM module, and monitoring and control through a website. The research method used was a system design and development approach, which included hardware and software design, system implementation, and performance testing. The system was built using an ESP32 microcontroller integrated with a vibration sensor, buzzer, GSM SIM800L module, relay, solenoid door lock, and a website as a remote monitoring and control platform. The results showed that the system was capable of detecting physical disturbances on the parcel box effectively through the vibration sensor. When vibrations exceeded the predefined threshold, the system activated an alarm and automatically made a call to the user. In addition, the system displayed the parcel box status in real-time and allowed users to control the locking mechanism via the website. Based on testing results, the system achieved an accuracy rate above 90% with a fast response time.
