Abstract

Banyak jenis tanaman memerlukan kondisi lingkungan tertentu agar dapat tumbuh secara optimal, namun kondisi lingkungan tempat penanaman sering kali tidak sesuai dengan kondisi lingkungan yang dibutuhkannya. Untuk menciptakan kondisi lingkungan yang sesuai dengan kebutuhan tanaman, biasanya diperlukan rumah kaca. Rumah kaca adalah bangunan yang berfungsi untuk memanipulasi kondisi lingkungan di dalamnya. Di Indonesia, pengaturan lingkungan rumah kaca kebanyakan masih dilakukan secara manual, sehingga ketergantungan pada manusia tinggi. Sistem pengaturan rumah kaca yang dirancang menggunakan mikrokontroler ATMega16 sebagai unit pemroses yang mengolah informasi waktu dari Real Time Clock DS1302 dan hasil pengukuran sensor suhu LM35 serta sensor suhu dan kelembapan SHT11. Data yang telah diolah tersebut digunakan mikrokontroler untuk mengendalikan suhu, kelembapan udara, dan penyiraman pada rumah kaca dengan mengatur kerja dari pemanas, kipas pendingin, humidifier, kipas sirkulasi, dan pompa penyiram. Hasil pengujian menunjukkan sensor suhu LM35 memiliki persentase kesalahan antara 0,14% - 0,67%, serta sensor SHT11 memiliki persentase kesalahan sebesar 0,36% untuk pengukuran suhu dan 3,11% untuk pengukuran kelembapan udara. Sistem pengaturan rumah kaca ini dapat berjalan dengan baik sesuai rancangan. Many types of plants require a certain environment in order to grow optimally, but the environmental condition of cultivation is often incompatible with the required environmental conditions. To create the environment according to the needs of plant, usually required greenhouses. Greenhouse is a structure that serves to manipulate the environmental condition in it. In Indonesia, most of the greenhouse environment settings are still done manually, so that the dependence on human is still high. Greenhouse control system that is designed uses microcontroller ATMega16 as its processing unit which processes time information from DS1302 Real Time Clock and measurements from LM35 temperature sensor and SHT11 temperature and humidity sensor. Data that have been processed by microcontroller is used to control temperature, humidity, and watering of the greenhouse by regulating the work of the heater, cooling fan, humidifier, exhaust fan, and watering pump. The test results show that LM35 temperature sensor has error percentage between 0.14% - 0.67%, and SHT11 sensor has error percentage 0.36% for temperature measurements and 3.11% for humidity measurement. This greenhouse control system can work well according to the design.

Abstract

Internet of Things or IoT is a technology that is currently trending, because it can help human in their daily routine. One of the IoT product that used in homes is smart speaker. However, every latest technological innovation does not escape from vulnerabilities and one of them is the microphone on the smart speaker. Several studies and research have found that security vulnerabilities in smart speakers, such as dolphin attacks and audio capture. To find out how this audio capture technique works, an experiment was made to understand how it works and the impact of this technique. This experiment uses a smart speaker with voice assistant Alexa, using the Alexa Skills Kit services and Flask-Ask framework to create an audio capture program. The results of this program testing are expected to be used as a benchmark to prevent smart speakers from becoming the target of this technique anymore.

Abstract

In the present era, machine intelligence, also known as Artificial Intelligence (AI), is demanded not only to execute specific commands but also to recognize, analyze, or even make decisions, thereby providing desired outputs. By harnessing the power of AI, it is anticipated that desired outcomes will be more accurate and goal achievement will be optimized, minimizing losses. With the capabilities of AI in mind, a research study has been conducted on AI's ability to analyze and make decisions based on specific data. In this study, data in the form of images of men and women were utilized. The objective of this research is to analyze the ability of AI, particularly in gender classification. The method employed in designing this system is Deep Learning, with GoogLeNet as the Convolutional Neural Network utilized. In testing, the data accuracy ranged from 61.8% to 100% for the system without training algorithm options and from 97.5% to 100% for the system with training algorithm options. Testing was also carried out on a smaller set of training data and grayscale images, yielding lower accuracy ranges. From this research, it can be concluded that the quantity of training data, image preprocessing, and training algorithm options are crucial indicators for enhancing prediction accuracy.

Abstract

Sorting goods based on the results of checking packaging labels is an important process in controlling production quality in industry. Many industries still carry out manual sorting and label checking processes, which results in low productivity levels and is susceptible to human error. This research develops an automation system for sorting goods based on label inspection using vision sensors, programmable logic controller (PLC), and robot arm. The system controlled by a PLC will read and detect damage to packaging labels by using VeriSens vision sensor and sort them using a robot arm according to predetermined stock keeping unit (SKU) categories, namely SKU 1, SKU 2, SKU 3, SKU 4, and rejected goods. The pneumatic system is used as an actuator to push goods onto the conveyor, moving the robot arm with three degrees of freedom and vacuum. Detection is carried out by applying the edge detection concept to read text, images and code that are reprocessed with the VeriSens Application Suite software. The success rate of the goods sorting system reached 90% with a reading speed of 0.389 seconds and a work process duration ranging from 21.54 seconds to 28.99 seconds.

Abstract

The development of information technology cannot be separated from the use of mobile applications, which are increasingly varied. Mobile applications allow users to easily connect to internet services anywhere. Cooperatives are joint business entities that generally still use the manual method for recording members, transactions and so on, which can lead to human errors and time inefficiencies. The existence of a website-based cooperative mobile application that is implemented on smartphones using the Xamarin.Forms framework can reduce these problems. Smartphones will make online cooperatives more effective because they are portable, easy to use and more affordable.

Abstract

A battery is a device that stores power in an Uninterruptible Power Supply (UPS) system. The most common type of UPS battery found today is Valve Regulated Lead Acid (VRLA). So that the UPS can work optimally according to its capacity and backup time, it is necessary to determine the battery capacity. In this research, the capacity of the VRLA battery on a particular UPS was determined based on direct testing and based on calculations. VRLA battery capacity calculations refer to the UPS and battery datasheet. The calculation stage starts from calculating the current and battery power used according to the load power absorbed by the UPS and referring to the table of constant current discharge and constant power discharge characteristics. Determining battery capacity based on testing is done by measuring the backup time of the UPS. The calculation results and test results directly show that there is a difference in backup time because the battery used is an old stock battery. The research results also prove that determining battery capacity by calculation can ensure that the battery capacity is more appropriate or not too large so it is more economical.

Abstract

Technological developments make it possible to monitor electricity consumption in real-time via the internet. The system developed uses a power meter to collect data, Python to process data and IoT connectivity via NodeMCU ESP8266 to send data to the internet. Python is used so that measurement data can be processed and presented in an easy-to-understand format. The test results show that electrical data measurements can be displayed with an error ranging from 0.04% -11.56%. This is because there is a delay from the time the power meter is measured until the data is displayed on ThingSpeak.
