Abstract

Jenjang kepangkatan merupakan salah satu parameter profesionalitas seorang Guru, sehingga Guru dituntut untuk terus menaikkan jenjang kepangkatannya. Namun, umumnya Guru mengalami permasalahan untuk mengajukan kenaikan jenjang kepangkatannya, dikarenakan minimnya publikasi ilmiah. Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilaksanakan untuk mengatasi permasalahan tersebut dengan cara meningkatkan kemampuan Guru agar mampu menyusun naskah publikasi ilmiah pada jurnal nasional. Kegiatan PkM ini dilakukan melalui kolaborasi tiga Perguruan Tinggi, yaitu IST AKPRIND Yogyakarta, Universitas AMIKOM Yogyakarta, dan Universitas Muria Kudus. Kegiatan ini merupakan pelaksanaan tahap pertama dari tiga tahap yang direncanakan. PkM ini dilaksanakan di SMK N 2 Magelang dengan durasi waktu 130 jam dan peserta sebanyak 31 orang dari. Langkah-langkah yang dilakukan meliputi: pengurusan perijinan dan survei, pengumpulan data, analisis kebutuhan mitra, penyusunan rencana program dan kegiatan, penyusunan dan penandatangan naskah MOU dan MOA para pihak, penyusunan modul kegiatan, pelaksanaan kegiatan, evaluasi pelaksanaan kegiatan, dan diakhiri dengan penyusunan laporan kegiatan. Berdasarkan hasil evaluasi pelaksanaan kegiatan ini disimpulkan bahwa materi PkM sesuai kebutuhan peserta, strategi kolaborasi lintas institusi Perguruan Tinggi memungkinkan setiap Pelaksana melaksanakan tugas sebaik-baiknya. Strategi kolaborasi PkM memerlukan koordinasi, pembagian tugas, dan penjadwalan yang baik agar pelaksanaannya berjalan dengan baik dan lancar sesuai program yang dirancang sehingga dapat mencapai tujuan yang ditetapkan.

Abstract

Mobile phones have limited memory and computational resources. Modern encryption algorithms such as DES, AES, IDEA uses a complicated and complex algorithm, that are not suitable for image encryption on mobile phones. Necessary, it is tradeoff between speed, security, and flexibility. Problem to be investigated and resolved is how to get the image encryption algorithm which is simple yet safe, with the lightweight and efficient computing. The algorithm developed in this study was super-encryption algorithm that combines Playfair cipher and the Vigenere cipher. The experimental results show the cipher image histogram has a distribution of diversity and a significant difference to the plain image histogram, and frequency of occurrence of each intensity value in the histogram of cipher image is also uneven, which means can not provide clues to do statistical attack. The experimental results also showed a correlation between the elements of the image after encryption has decreased significantly. The average of quality encryption showed that the rate of change of image pixels is high enough so that cipher image difficult to identify. Tests on a cell phone showed that this algorithm requires only small computational resources. This shows that the algorithm is quite effective for image encryption on mobile phones.

Abstract

The average temperature of global warming on the earth's surface today has increased by 0.74 ± 0:18°C, the increase was due to the increase in the average temperature of the atmosphere, ocean and land earth. Emissions of the most influential on the quality of the air is carbon emissions, especially carbon dioxide (CO2). The CO2 contributes to global warming is 50%. The CO2 gases absorb and reflect radiation emitted waves of the earth, so that the heat will be stored on the surface of the earth. This study aimed to design a data logger system monitoring the level of concentration of CO2 using the oxygen sensor (OOM202), carbon dioxide sensor (MG81), as well as temperature and humidity sensors (DHT22) with microcontroller-based SMS gateway information. The study tested are simulated in the laboratory with electronic testing and testing communication systems. The test results showed good performance with the prototype, the results of monitoring CO2 emissions seen huge levels of carbon dioxide (ppm) is proportional to the output voltage (Vout) is generated. The greater the concentration levels of gas detected by the sensor, the output voltage generated will be greater, than that difference or distinction ADC output between the measured and calculated because of several errors, such as error output ADC ± 2 bits, error rounding conversion of ADC to volt. The measurement results are different, in the closed and open area refers to the measurement parameters are displayed on an alphanumeric display. Measuring system can transmit data via SMS information system with an average response time of less than 1 minute, it depends on the quality of the signal and traffic data from a provider by the user.

Abstract

INTISARI Industri pengolahan hasil pertanian dan perkebunan sangat berkembang pesat. Salahsatu tahap dalam proses pengolahan hasil perkebunan adalah pemilahan produk berdasar kualitasnya (misalnya tingkat kematangan buah). Proses pemilahan produk hasil pertanian dan perkebunan umumnya sangat bergantung pada persepsi manusia terhadap faktor komposisi warna yang dimiliki citra (buah-buahan). Persepsi manusia terhadap suatu citra cenderung didominasi oleh faktor komposisi warna yang dimiliki citra. Dengan histogram dapat dicari citra yang memiliki kemiripan komposisi warna. Pengukuran tingkat kemiripan dilakukan dengan menghitung jarak antar histogram. Komposisi warna dapat ditampilkan dalam bentuk histogram yang merepresentasikan distribusi jumlah piksel untuk tiap intensitas warna dalam citra. Dalam penentuan tingkat kematangan buah apel, dapat ditentukan berdasarkan komposisi warnanya. Sebagai pembanding adalah histogram warna buah yang sudah matang. Sedangkan query berupa buah apel yang akan dibuat histogram kemudian dibandingkan. Sistem deteksi kemiripan citra yang telah dibuat dapat menemukan kemiripan antar citra berdasarkan nilai jarak antar histogramnya. Informasi yang dihasilkan berupa prosentase kemiripan dan penggolongan kematangan buah yang meliputi mentah, mengkal, dan matang. Ini dibuktikan dengan hasil percobaan pada program yang telah dibuat menunjukkan bahwa citra yang memiliki kemiripan distribusi warna citra yang sama persis memiliki selisih jarak sama dengan nol. Kata kunci : , histogram, komposisi warna,
