Abstract

Madura merupakan salah satu daerah penghasil tembakau di Indonseia. Tembakau Madura  merupakan jenis komoditi perkebunan yang memiliki nilai ekonomi tinggi. Sebagian besar tembakau madura diserap oleh pabrik rokok sebagai bahan baku utama rokok maupun sebagai racikan atau campuran kretek. Secara umum tembakau Madura sendiri dibagi menjadi tiga bagian: tembakau gunung, tembakau tegal, dan tembakau sawah. Jenis tembakau gunung adalah yang paling diburu oleh pabrik rokok, meski produktivitasnya terbilang sangat rendah dibanding tembakau sawah. Terdapat banyak jenis  varietas tembakau gunung yang ditanam petani di Madura, namun  yang memiliki karakteristik khas adalah tembaku Prancak – 95. Hal ini disebabkan  Aroma tembakau Prancak-95 Madura tidak bisa ditiru oleh jenis varietas tembaku lain di Indonesia. Hal lain yang membedakan yaitu terjadi karena kontur atau struktur tanah Madura yang memang khas, yang merupakan kelebihan dari tembakau Madura.Pada penelitian ini didesain sebuah sistem gradding untuk mendeteksi kualitas tembakau Prancak – 95 madura. Deteksi kualitas daun tembakau ini didasarkan pada dua ekstraksi fitur yaitu tekstur dan aromatik. Berdasarkan kedua fitur tersebut nantinya akan diklasifikasikan dengan menggunakan standard kualifikasi SNI. Sehingga  level akurasi deteksi kualitas daun tembakau Madura menjadi lebih optimalKata Kunci: Image extraction, Sensor Gas, Tembakau Madura.Implementation of Feature Image Extraction on Quality Classification of Maduraness TobaccoABSTRACTMadura is one of the tobacco producing areas in Indonesian. Madura tobacco is a type of plantation commodity that has high economic value. Most tobacco Madura is absorbed by cigarette manufacturers as the main raw material of cigarettes as well as as a concoction or clove mixture. In general Madura tobacco itself is divided into three parts: mountain tobacco, tobacco tegal, and tobacco sawah. Types of mountain tobacco are the most hunted by cigarette manufacturers, although the productivity is very low compared to tobacco. There are many types of varieties of mountain tobacco grown by farmers in Madura, but which has a distinctive characteristic is the Prancak-95 tobacco. This is because the Prancak-95 Madura tobacco aroma cannot be imitated by other types of copious varieties in Indonesia. Another thing that distinguishes that occurs due to the contour or structure of Madura land that is typical, which is the advantage of Madura tobacco. In this study designed a grading system to detect the quality of Prancak tobacco - 95 madura. The tobacco leaf quality detection is based on two feature extractions, namely texture and aromatics. Based on these two features will be classified using SNI qualification standards. So that the accuracy level of Madura tobacco leaf quality detection becomes more optimalKeywords: Image extraction, Gas Sensor, Maduraness Tobacco

Abstract

PLTMH (Pembangkit Listrik Tenaga Mikrohidro) dibangun setelah melalui studi kelayakan yang matang dengan parameter: debit air, ketinggian, jenis generator dan lain-lain, sehingga pada saat diberi beban maksimum maka generator masih mampu menghasilkan tegangan dan frekuensi yang sesuai dengan standar. Tetapi PLTMH belum dimanfaatkan secara maksimal sehingga perubahan beban pada konsumen menyebabkan terjadinya fluktuasi tegangan dan frekuensi karena kecepatan generator akan cenderung berubah-ubah pula, dan dalam kenyataannya perubahan yang terjadi tidak dapat dimonitor setiap saat. Perubahan beban yang sering terjadi pada sebuah PLTMH dapat mengakibatkan kestabilan frekuensi menjadi terganggu. Selain itu juga dapat mengakibatkan roda gerak berputar lebih cepat. Akibatnya frekuensi listrik akan naik dan bila terlalu tinggi akan membahayakan peralatan listrik konsumen. Oleh karena itu, untuk menunjang kinerja PLTMH ini, pengaturan atau pengendalian frekuensi sangat diperlukan agar selalu berada pada daerah kerja antara 49 Hz – 51 Hz. Tujuan makalah ini untuk merancang sistem kontrol pembagi beban elektronik menggunakan kontrol sudut penyalaan (firing angle) pada generator pembangkit Listrik Tenaga Mikrohidro (PLTMH), agar beban dari generator dalam hal ini adalah beban konsumen tidak mengalami kerusakan dengan menggunakan mikrokontroler ATMega 16. Pengendalian beban dimaksudkan untuk menjaga kestabilan energi listrik yang dihasilkan oleh generator. Dengan bekerjanya triac maka jika terjadi penurunan daya pada konsumen, sisa daya akan mengalir ke beban komplemen, sehingga daya generator senantiasa tetap walaupun beban konsumen mengalami perubahan. Hasil pengujian alat menunjukkan jika beban uji berkisar antara 205 Watt sampai dengan 213 Watt maka frekuensi beban berkisar antara 49 Hz sampai dengan 51 Hz.MHP (micro hydro power plant) built with a study using the parameters: water flow, heights, types of generators and others, so that when given the maximum load the generator is able to generate a voltage and frequency in accordance with the standard. But the MHP has not been utilized to the maximum so that the change in the burden on consumers caused fluctuations in voltage and frequency as the speed of the generator will tend to vary as well, and in fact the changes can not be monitored at all times. Load changes that often occur at a frequency stability of MHP can result becomes impaired. It also can result in motion the wheels spin faster. As a result, the electricity frequency would endanger consumer electrical appliances. Therefore, to support the performance of this MHP, we need frequency control to keep this always be on the working area between 49 Hz - 51 Hz. An Electronic Load Controller (ELC) is an electronic device that keeps the speed of synchronous generator constant at varying load conditions. The generator is driven by unregulated turbine with constant power output and a dummy ballast load is connected across the generator terminals to dump the excess of power generated. When the consumer’s load changes, frequency of generated voltage changes. This research deals with the electronic load control settings prototype using a microcontroller ATMega 16. Load control is used to reduce the overloading of the generator by using firing angle control. The triac is used to control the power consumed by ballast of each phase and the change in load in one phase doesn’t affect the dummy power consumption of other phases. The test result show if load testing tools ranging from 205 Watts to 213 Watts then load the frequency range between 49 Hz to 51 Hz.

Abstract

Understanding the history of a nation is very important. Inscriptions are an important historical relic for the nation. Inscriptions provide information and learning for future generations. Inscriptions are usually made of stone or metal. There are several problems in reading the inscription, such as smearing which affects the readability of the writing, erosion of the smear or other things which reduce the legibility of the inscription. On the other hand, Javanese script is a way of writing Javanese instead of using Latin script. It is quite difficult to understand and memorize Javanese script because of its shape and rarely used. Archaeologists in Indonesia generally use fairly simple tools to read inscriptions so it takes a long time. This adds complexity to the process of documenting existing inscriptions. Therefore, in this research a tool was designed to read and translate inscriptions using the principle of light reflection. This is the main contribution and novelty of this research. The data that has been obtained is then processed using image processing and interpreted from Javanese to Indonesian. The method used is YOLO (You Only Look Once) to process image processing. Adding light around the inscription using LED strip lights. From the experiment, the success rate was 88.5% and the failure rate was 11.5%. The intensity of the light and the accuracy of the angle of incidence of the light greatly influence the level of success in reading the writing on the inscription.
