Abstract

n this research it has designed a turbidity sensor system to determine the parameters of turbidity in water that can be consumed, using the nephelometry method. Nephelometry is a method in utilizing the nature of light scattering, light sources emitted into water media containing particles that will be scattered and detected by light detectors positioned at 90 ° angle. In this work the light source was used a super bright red LED and a TSL 250r photodiode light detector with a wavelength of 630nm. This paper will also explain process of making sensor and the turbidimeter system on the basis of Raspberry Pi 3. The results of the turbidimter sensor characterization obtained with the least square equation are y = 232.51x-61.29, the formula is can be used to change the ADC value to NTU (Nephelometer Turbidity Unit). The turbidity sensor has an accuracy of a minimum value is 2 NTU and a maximum value is 200 NTU with an error under 5%.

Abstract

Abstract - At the moment, people who use electricity as their daily necessities still use the methods that have been in the past, namely by purchasing an electric voucher that has been available several digits of code entered into the prepaid kWh meter via the keypad. This method is considered to be less effective and less efficient in a period that has experienced a lot of progress, especially in the field of technology. Especially when the electric pulse has reached the minimum limit of the prepaid kWh meter, it only gives a warning to the sound of the buzzer alarm, it can only be heard by the customer if he is inside the house. so that the customer cannot find out if the customer is out of the house. Automatically the kWh meter customer is not prepared to deal with it if the user is not at home. So from that the research that will be made is a prototype prepaid kWh meter based on Short Message Service (SMS). In addition to being able to control the remaining electricity pulses remotely, this tool will also be able to charge electric pulses without having to enter the voucher code into the kWh meter directly but with this tool the customer can fill in by sending a short message or SMS set by the customer. The system contained in this Short Message Service (SMS) prepaid kWh meter prototype is controlled by 16 ATM AVR Microcontrollers. When the prepaid kWh meter value shows a value of 5 kWh, the system automatically provides information on the remaining kWh meter electricity through short message or SMS and marked with the buzzer sound and LED indicator. That will be made is considered to be more effective and flexible. From the results of the research data that have been collected, it can be seen that the performance of SMS-based prepaid kWh meters with the overall test results is successful and the percentage of success almost reaches 100%.

Abstract

Abstract – Bicycles has become the best solution to be able to reduce the level of congestion for the citizens of the world. Cycling is an activity carried out by someone to be able to go from place to destination and cycling has also become a hobby for some people. Even so, bicycles also experience infrastructure problems, namely bicycle lanes which are still rarely available. Some countries in the world have not fully provide special lanes for bicycle users. This causes bicycle users to use highways that are more often used by other vehicles. And it can cause accidents for bicycle users. Therefore, in the implementation of the wireless indicator lights on this jacket, the author wants to provide a better solution to overcome this problem, that is by combining indicator lights with jackets so that it can function to signal to other road users. In Addition, the author also designed a digital speedometer that can later appear on the LCD screen (liquid crystal display). For this speedometer, by placing a magnetic sensor on the forks as a magnetic speed reader placed on the bicycle spokes. For indicator lights on this jacket, the input uses a touch sensor and brake levers will be attached to the front of the bike through the bluetooth master transmission system and the bluetooth slave on the jacket, so the indicator light on the jacket will light up and form the right, left or stop direction and will be displayed on the LCD with the digital speedometer.Keyword : Speedometer, Bluetooth, Bicycle, Indicator Light, Wireless

Abstract

Abstract - In the manufacturing process of tofu, tofu produces two kinds of waste, namely solid waste and liquid waste. Tofu liquid waste can be used as liquid organic fertilizer. One way to treat tofu liquid waste is to make liquid organic fertilizer, namely by mixing tofu liquid waste with raw water, acid solution and also alkaline solution so that it can be used as liquid organic fertilizer. This study aims to design and produce a monitoring and control system that is able to produce liquid organic fertilizer for lettuce plants that are cultivated hydroponically with the help of technological engineering. The application of technology in the process of making liquid organic fertilizer and also the fertilization process, one of which is the application of technology based on the Internet of Things (IoT) which can provide important information such as the level of nutritional needs, temperature and pH as a reference for the success of fertilization which can be monitored and controlled for the limits of its needs. at all times. Liquid organic fertilizer produced with the help of a system designed has met the quality standard of liquid organic fertilizer which has a nutrient concentration level with a value range of 810.14 ppm to 839.81 ppm, a temperature value range of 26.28℃ to 27.18℃ and a pH with the range of values ​​is 6.11 to 6.99 where this can be proven by referring to the Decree of the Minister of Agriculture No: 261/KPTS/SR.310/M/4/2019 concerning the minimum technical requirements for organic fertilizer and the regulation of the Minister of the Environment of the Republic of Indonesia No. .5 of 2004 concerning the value of waste quality standards. The result of this system produce lettuce wich has a weight 25 grams and a height of 20 cm.

Abstract

Salah satu bidang penelitian mendasar dalam robotika adalah algoritma perencanaan gerak atau jalur. Pada penelitian ini dirancang dan disimulasikan algoritma quick -exploring random tree* (RRT*). Algoritma yang diusulkan adalah algoritma RRT* goal biasing dan algoritma RRT* g aussian sampling . Tujuan penelitian ini adalah melakukan analisa performansi perencanaan jalur algoritma RRT* goal biasing dan algoritma RRT* gaussian sampling . Pengujian dilakukan menggunakan beberapa kasus benchmark yang ada, yaitu lingkungan narrow , trap , dan clutter. Parameter yang dibandingkan adalah biaya, waktu komputasi, dan total node yang dibutuhkan pada pohon pencarian dari node awal sampai node tujuan. Menggunakan kasus benchmark lingkungan narrow, clutter, dan trap algoritma RRT* goal biasing memperoleh nilai rata-rata untuk biaya jarak, waktu, dan jumlah node yaitu; 8,3 (biaiya jarak di narrow ), 222,1 (jumlah node di clutter), dan 30.045 detik (waktu di trap) . Kemudian untuk kasus benchmark lingkungan sempit, clutter, dan trap yang menggunakan algoritma RRT* g aussianmemperoleh nilai rata-rata untuk biaya jarak, waktu, dan jumlah simpul yaitu; 8,1 (biaiya jarak di narrow ), 642,85 (jumlah node di clutter), dan 30,49 detik (waktu di trap) . Berdasarkan pengujian algoritma RRT* goal biasing memiliki keunggulan untuk waktu dan jumlah node yang dibutuhkan untuk mencapai suatu titik, tetapi biaya jarak yang dihasilkan kurang optimal.
