Abstract

Liquid Petroleum Gas (LPG) has a drawback in its use that it is very prone to cause fires because it is a hydrocarbon in the form of propane and butane. LPG storage must also use a strong cylinder and has no leakage. If the gas storage cylinder leaks, it will easily cause fire and explode when it is used. LPG must meet several particular criteria in terms of safety, so it does not damage the equipment used and can be efficient in its use. A gas leak detection system is required to reduce the risk of material and life loss due to gas cylinder leaks, which can later be used as a safety system or warning of gas leaks. The users can quickly response to gas leaks around them. The warning given can be a short message or an alarm as a reminder to the users. The purpose of this research is, first, to create an LPG gas leak pressure measurement algorithm using the MQ6 sensor and GSM SIM 900A for a Smart home. The second is to design an Arduino-based gas leak notification through an SMS Gateway. The method used in this study is experimental. This is a method that is generally used in laboratory research. The second is the prototype method, in which the device changes are carried out many times until the goal of the device to be developed is achieved. The research results are the first to produce an algorithm for measuring LPG gas leakage pressure using the MQ6 sensor, which can be installed in Smart home, testing this algorithm using a board on the Arduino microcontroller, which is connected directly to the MQ6 sensor as an input medium. After the algorithm is embedded to measure the gas leak pressure on the MQ6 sensor, it works as a sensor that only detects LPG, propane, butane and its types explicitly. In the results of trials that have been carried out by going through 4 stages of testing this detector, it will be more optimal to detect gas leaks at a distance of 5 cm. The second is to generate Arduino-based gas leak notification information using an SMS Gateway. This tool is also equipped with a GSM SIM 900A module that functions as an SMS gateway so that if a gas leak occurs, the GSM SIM 900A can be a communicator among the user's mobile devices to provide information via SMS. The better the quality of the available network, the faster the notification will be sent.

Abstract

This study focuses on the visitors of Pohon Cinta beach tourist area. This beach is one of the potential tourism objects in Pohuwato Regency. The main problem that frequently occurs is that many visitors cannot directly convey their impression when visiting and enjoying the beauty of the Pohon Cinta beach. The government needs to know the level of visitor satisfaction to attempt to improve and develop the Pohon Cinta beach tourist attraction. Thus, to solve the problem above, a method that can help predict visitor satisfaction is needed. This study aims to measure visitor satisfaction through predictions using the Backpropagation algorithm and PSO feature selection to assist the government in developing tourism potential in Pohuwato Regency. The method used is the backpropagation algorithm for prediction and Particle Swarm Optimization which is considered effective in overcoming optimization problems. This algorithm is considered capable of solving problems in the backpropagation algorithm. The accuracy value of the backpropagation algorithm model is 84.67%, the accuracy value of the PSO-based backpropagation algorithm model is 85.00%, and the difference in accuracy is 0.33. The results of the application of the Backpropagation algorithm and Particle Swarm Optimization can increase the predictive accuracy value of visitor satisfaction at the Cinta Tree Beach tourist attraction.

Abstract

Today's technology makes communication very easy and can be used anywhere, even a distance of hundreds to thousands of kilometres is not a barrier in communicating. One of the tools or media that is widely used is via email. However, there are many disadvantages that may be obtained from the email, one of which is spamming or mail. The purpose of this research is to know the stages of spamming email analysis through header analysis. The method used in this study is the National Institute of Standards and Technology (NIST) and this method uses 4 stages, namely collection, examination, analysis, and reporting. The results of this study are expected to be able to find out the spam sender's email address, the spam email sender's IP address, and other information needed.

Abstract

The scarcity of fossil fuel sources and the growing energy demand has resulted in more intensively searching for alternative energy. One alternative energy source that is suitable for the equatorial region is solar energy. One of the technologies for utilizing solar energy that has begun to be widely used in Indonesia is the photovoltaic (PV) system. The output of PV is highly dependent on environmental conditions, especially the intensity of the sun and temperature. In addition to these two factors, shading (shadows) and soiling (dust) also affects the PV output. So, this must be observed at all times by monitoring the voltage and current as the PV output. This study aims to design a PV panel instrumentation structure based on a data logger. PV output data in the form of voltage and current and environmental conditions such as ambient temperature and solar intensity were recorded in real-time. The measurement results from the data logger will be compared with manual measurements. PV output data, output voltage and current, as well as sunlight intensity were compared with measurements using an avometer. Temperature data will be compared with thermocouple measurements. PV in this study will be connected to a 1kOhm load resistor. The results of the data logger and manual measurements indicated an insignificant difference. The manual measurement was conducted every hour, from 09.00 – 16.00. The maximum differences for voltage, PV output current, pyranometer voltage, and ambient temperature are 0.89 V, 0.0007 A, 0.00014 V, and 0.25oC, respectively.

Abstract

The Academic Information System (in Indonesian often abbreviated as SIAKAD) is a system developed to manage student data that aims at facilitating online academic administration activities. It aims to provide academic information services in the form of web applications, where teachers can independently create student academic reports to synchronize data into the DAPODIK system, a primary education data system, and develop academic information systems using web assembly according to user experience (UX) and developer experience (DX). The research method consists of field studies and literature related to web assembly, primary education data (DAPODIK), and the Academic Information System (SIAKAD). This information system and database were built using the Convention Over Configuration paradigm. The design phase used a prototyping model to graphically represent the system workflow and used an experimental research approach. Moreover, the study used an integrated modeling language (UML), and a Database Management System using PostgreSQL, and alpha testing for model testing. The Client Application was built using the C# programming language for users to generate student academic reports every semester. Processing data transactions using web assembly took less time than the traditional web, which was less than 300 milliseconds.
