Abstract

A significant increase in consumption of natural resources in the household sector is the use of LPG (Liquefied Petroleum Gas) gas, this can increase the risk of fire due to leaks from gas cylinders. These gas leaks are often unknown to users because not all LPG cylinder manufacturers provide a security system for the LPG cylinders they sell, so not all homes have gas leak sensors on LPG cylinders, therefore a tool is needed to detect LPG gas leaks. In view of these problems, in this research a device was created that can detect gas in a room with an MQ-2 sensor and apply a notification system using Telegram as an SMS notification sender and a buzzer as an alarm. The design of this detection tool as a whole is controlled by the NodeMCU ESP8226. During system testing, when a gas leak is detected at a distance of 1cm – 100cm with the MQ-2 sensor, the system will provide a notification via Telegram and activate the alarm (the buzzer will beep). The process of sending this message takes around 4-6 seconds. The tool was also tested on two different cellphones and obtained the expected results and good performance.

Abstract

Reading books is one of the most effective ways to reduce stress. In today's digital era, access to finding and buying books is getting easier, so reader reviews are important in choosing books that match interests. However, with a large number of reviews, Natural Language Processing (NLP) with the Long Short-Term Memory (LSTM) method is used to help analyze positive and negative sentiments from many book reviews. This sentiment analysis is useful for readers to evaluate the quality of books, as well as for authors and sellers to find out the opinions of readers and improve the quality of their work. In this study, the book review dataset "Vera Wong's Unsolicited Advice for Murderers" from the Goodreads website is used, which is then divided into training data and validation data with a ratio of 75%: 25%. The Long Short-Term Memory (LSTM) method is used to analyze the sentiment of the reviews. The model architecture built consists of Embedding Layer, LSTM Layer with 128 neuron units, 3 Dense Layer with ReLU activation function, 3 Dropout Layer, and Fully Connected Layer with and Sigmoid activation function, Binary Cross Entropy loss function, and RMSprop optimizer. The model training process was conducted with 30 epochs. The evaluation results show that the model achieved an accuracy of 90%, indicating the model performs relatively well in correctly classifying positive sentiments.

Abstract

Sampah merupakan sesuatu yang sudah tidak terpakai lagi atau sesuatu yang tidak disukai lagi dan dibuang dari sisa kegiatan manusia atau proses alam yang berbentuk zat organik anorganik, terurai tidak terurai. Sampah dapat dikelompokkan menjadi dua jenis yaitu sampah organik dan sampah anorganik. Membuang sampah berdasarkan jenisnya dapat menimbulkan dampak positif bagi lingkungan. Pemilahan sampah berdasarkan jenisnya sebelum dibuang memiliki peran penting dikarenakan pembusukan dari sampah menjadi sempurna. Tujuan penelitian ini adalah menerapkan sensor capacitive dan infrared proximity terhadap pembuatan tempat sampah yang dapat memilah jenis sampah organik dan anorganik. Selain itu Motor servo akan melakukan buka tutup tempat sampah setelah sensor capacitive proximity dan sensor infrared proximity mendeteksi sampah. Tempat sampah akan dideteksi penuh dengan menggunakan sensor ultrasonik dan buzzer akan mengeluarkan suara dengan tujuan agar tempat sampah dikosongkan. Semua komponen dihubungkan dengan kabel jumper ke Arduino Uno yang telah diprogram menggunakan Arduino IDE. Pengujian alat ini dilakukan dengan cara menghubungkan power bank ke Arduino Uno menggunakan kabel USB, menekan power on pada power bank dan semua komponen, yakni sensor capacitive proximity, sensor infrared proximity, motor servo, sensor ultrasonik, serta buzzer akan aktif berfungsi sesuai dengan tujuannya.

Abstract

In the world of health, a platform is needed to make it easier for a person to find information, especially related to drugs practically. To realize this, this research was carried out to produce an application called InMed (Information Medicine). This research aims to analyze, design, and evaluate matters related to telemedicine and make it easier for users to find information about medicines. The method used in this study is Goal Directed Design (GDD) which consists of several steps, namely Research, Modeling, Requirements, Framework, Refinement, Support. The results of the Likert Scale test of the InMed application prototype received a score of 92%.
