Abstract

Hingga saat ini masa subur atau ovulasi pada wanita dapat di ketahui dengan metode servik, monitoring suhu basal, metode peak day dan metode standard day. Dalam penelitian ini dikembangkan metode saliva ferning, yaitu dengan mendeteksi melalui kristal air liur. Citra saliva ferning didapat melalui mikroskop digital dengan perbesaran 100 kali. Citra akan diklasifikasikan berdasarkan pola citra dengan pola acak, pola titik garis dan pola garis yang dominan. Berdasarkan perbedaan pola citra maka akan diklasifikasikan untuk menentukan masa tidak subur, masa transisi, dan masa subur yang sedang berlangsung. Nilai piksel dari citra akan diidentifikasi menggunakan metode hidden markov model dan ditampilkan pada smartphone android. Hasil penelitian menunjukkan nilai piksel, untuk masa tidak subur sebesar 8463 hingga 33302, masa transisi 39442 hingga 77315 dan masa subur diatas 77702, dengan akurasi identifikasi sebesar 95%. Sampel saliva yang baik yaitu saliva yang tidak terkontaminasi, umumnya di pagi hari setelah bangun tidur.

Abstract

Pembangkit tenaga listrik thermal merupakan suatu pembangkit yang menghasilkan energi listrik yang berasal dari energi thermal. Energi thermal bisa dihasilkan melalui pembakaran bahan bakar berupa gas ataupun batubara. Berdasarkan hal tersebut, pada pembangkit tenaga listrik thermal konsumsi bahan bakar sangatlah mempengaruhi biaya produksi energi listrik, sehingga diperlukan suatu teknik pengoperasian pembangkit yang optimum. Salah satunya pada PT Indonesia Power UPJP Perak Grati yang merupakan perusahaan pembangkitan tenaga listrik yang dalam pengopeasiannya memerlukan cara dalam penghematan bahan bakar gas berdasarkan nilai heat rate (Kcal/kWh) khususnya dalam penghematan biaya pokok produksi. Pada penelitian ini Particle Swarm Optimization (PSO) digunakan sebagai metode untuk penentuan daya optimal pada generator Pembangkit Listrik Tenaga Gas (PLTG) Perak Grati. Berdasarkan hasil penelitian, dihasilkan adanya penghematan konsumsi gas antara metode PSO dengan kondisi aktual, dimana saat permintaan daya 310 MW, terjadi penghematan konsumsi gas sebesar 0.5968 BBTU/h atau setara dengan Rp 57.168,00/h.Pembangkit tenaga listrik thermal merupakan suatu pembangkit yang menghasilkan energi listrik yang berasal dari energi thermal.

Abstract

Motorized vehicles are currently circulating a lot on the streets. Every motor vehicle produces what is called exhaust gas or what we often call motor vehicle emissions. By monitoring the exhaust gases produced by the vehicle, it means that the vehicle owner is much more concerned about the pollutants that can be produced by the vehicle itself, so that the vehicle owner can minimize the pollutants produced by the vehicle. This tool for monitoring the emission of wifi-based motor vehicles uses several components including Arduino uno, nodemcu esp8266, mq2 sensor, mq7 sensor with applications as program support, namely Arduino Ide, Firebase. The testing of this motor vehicle emission monitoring device is carried out by placing the mq2 and mq7 sensors right in front of the exhaust as the place where the vehicle's emissions come out. The comparison of the vehicle test results was carried out to see how much carbon monoxide and carbon dioxide levels were produced in each vehicle after being tested using the tool where the average carbon monoxide content for avansa vehicles was 13.56 ppm, ignis vehicles was 12.84 ppm, and innova vehicles were 175.02 ppm. While the recommended carbon monoxide level < 25 ppm, vehicles that have carbon monoxide levels above (Threshold Value) do not pass the emission test. And for the average carbon dioxide level testing in avanza vehicles of 385.7 ppm, ignis vehicles of 302.6 ppm, innova vehicles of 956.4 ppm. While the recommended carbon dioxide level < 450 ppm, vehicles that have a carbon dioxide content value above (Threshold Value) do not pass the emission test. Keywords : Motor vehicle emissions, MQ2 and MQ7 sensors as CO2 and CO detectors for monitoring.

Abstract

Security system technology is very important. With a motorbike lock security system using E-KTP as a tag, it is hoped that it can add security to motorbikes. The security system used on motorbikes today is still not safe enough because it still is has a limited security system. Therefore, a additional be tter security systems are needed on the vehicles themselves and are easy to use by the vehicle owner. This research aims to design additional prototypes for Arduino UNO based motorcycle security system that can be used for maintenance motorcycle safety. The method used is to utilize the radio wave frequency from the E-KTP and attach it to the RFID Reader and Arduino UNO. The results and analysis of the testing system are that the maximum reading distance between the E-KTP and the RFID Reader is 1 cm.  It is hoped that this research can be used to help fulfill a motorbike security system using E-KTP as a tag with radio Frequency Identification Technology (RFID).

Abstract

It's hard to know if one person does it. All this time, checking the rear lights is done conventionally by looking directly behind the car and requiring two people, such a way is less efficient. Besides, the car owner needs to know the location of the car, if the car is out of control of the owner. The research builds a light monitoring system and a car location tracker with a button to turn off the engine remotely using a smartphone. The research uses ACS712 sensors, Arduino Mega, Buzzer, LCD 16x2 with I2C modules, NodeMCU ESP8266, GPS module, WIFI modem, Relay module and the MIT APP Inventor Android app. This system's communication protocol uses the MQTT protocol, and the broker of this system uses the private broker's cloud. Researching the monitoring of lights using Panther and Genio cars, the system can distinguish when there are sensors that don't detect current, the buzzers are ringing and the LCD displays the "Lamp Off" character, as well as showing which lights are switched off. When all the sensors detect current then the buzzer is off, and the lcd displages the "OKE SYSTEM". The tracker system can display coordinate points and can be integrated with google maps. As well as the relay module can be controlled using buttons on the application so that the machine can die. This whole system uses smartphones remotely
