Songket is a woven fabric created by prying the threads and adding more weft to create an embossed decorative pattern on a cotton or silk thread woven background. While songket from many places share similar motifs, when examined closely, the motifs of songket from various regions differ, one of which is in the Province of West Nusa Tenggara, namely Lombok Island. To assist the public in recognizing the many varieties of Lombok songket motifs, the researchers used digital image processing technology, including pattern recognition, to distinguish the distinctive patterns of Lombok songket. The Gray Level Co-occurrence Matrix (GLCM) technique and Backpropagation Neural Networks are used to build a pattern identification system to analyze the Lombok songket theme. Before beginning the feature extraction process, the RGB color image has converted to grayscale (grayscale), which is resized. Simultaneously, a Backpropagation Neural Network is employed to classify Lombok songket theme variations. This study used songket motif photos consisting of a sample of 15 songket motifs with the same color theme that was captured eight times, four of which were used as training data and kept in the database. Four additional photos were utilized as test data or data from sources other than the database. When the systemâ€™s ability to recognize the pattern of Lombok songket motifs is tested, the maximum average recognition percentage at a 0Â° angle is 88.33 percent. In comparison, the lowest average recognition percentage at a 90Â° angle is 68.33 percent.

The mangosteen fruit has a characteristic thick skin, so it is difficult to know the condition of the flesh. Farmer can only know damage to the fruit flesh after the fruit skin had opened. Detection of the quality of the mangosteen flesh can be detected using a sensor capable of penetrating the thickness of the mangosteen rind. Flesh quality detection is carried out based on the S21 value (attenuation of mangosteen flesh value) using a portable device equipped with a sensor and capable of emitting microwaves. The S21 value of the fruit's flesh was measured using a spiral resonator that functioned as a sensor. The prototype device consists of an oscillator circuit, a power splitter, and a phase detector with 2507 MHz. Fruit flesh had divided into two conditions: damaged for fruit flesh with yellow sap or Translucent Flesh Disorder, and suitable condition for clean fruit flesh. The results showed that the fruit flesh had an average S21 value of 7.041 dB for damaged flesh and 6.007 dB for good flesh condition. The difference in the value of S21 had used as a reference for detecting the shape of the fruit flesh, with the detection threshold calculated by the Support Vector Machine, resulting in a threshold value of 6.712 dB.

Handphone menjadi perangkat yang banyak digunakan oleh masyarakat untuk menunjang kegiatan sehari-hari. Kegiatan tersebut meliputi pendidikan, ekonomi, hiburan, sosial maupun kegiatan keagamaan. Handphone dapat digunakan dengan baik apabila didukung oleh sarana infrastruktur termasuk tersedianya tower BTS (Base Transceiver Station). BTS ini berfungsi sebagai tranceiver yaitu dapat memancarkan sinyal (transmitter) dan menerima sinyal (Receiver). Penetuan lokasi BTS dipengaruhi oleh beberapa hal, antara lain: jangkauan, jumlah penduduk dan demand. Desa Pengengat berada di lingkar Kawasan Ekonomi Khusus (KEK) Mandalika masih terdapat beberapa titik yang tidak terjangkau oleh sinyal handphone. Hal ini di sebabkan kondisi geografis desa pengengat yang berbukit-bukit yang mengakibatkan sinyal seluler yang dipancarakan dapat terpantul dan terbias. Kondisi ini menyebabkan sinyal menjadi lemah dan menyebabkan beberapa titik area menjadi blankspot. Kegiatan Pengabdian ini mampu memberikan solusi berupa peningkatkan kualitas Sinyal yang sebelumnya sebesar satu bar menjadi lima bar. Pengujian menggunakan panggilan telepon menunjukkan kualita susarayang bagus. Pengujian kualitas internet menunjukkan kualitas suara dan gambar video yang baik. Kemudian dilanjutkan dengan kegiatan pelatihan penggunaan dan perawatan peralatan repeater kepada warga dan pemuda Karang Taruna Dusun Papak Desa Pengengat Kabupaten Lombok Tengah.

Chemical laboratories require additional equipment that is used as a mixer into the solution or chemical to be studied. The mechanism that is often used to accelerate the process of dissolving or mixing chemicals is heating and stirring. In addition to dissolving faster, the resulting solution will also be more homogeneous. In this research a Hot Plate Magnetic Stirrer was designed and manufactured by setting the time, temperature and stirring speed via a keypad so that accurate time, temperature and speed were obtained. The Hot Plate Magnetic Stirrer made in this study uses an infrared sensor to detect the speed of stirring, and an NTC 3950 sensor which is immersed in the solution to detect the temperature of the solution during stirring. The Hot Plate Magnetic Stirrer tool that has been made can run as expected. In the stirring time test, the system will work according to the input time. In testing the stirring temperature the system can maintain the stability of the solution temperature as desired with a maximum temperature of 110˚C. In the stirring speed test, the maximum speed of stirring was obtained, namely 1500 RPM when stirring using a beaker glass with a diameter of 6 cm and a bar magnet length of 4 cm.

The 5G network has been used in Grand Prix 1 (GP-1) in Indonesia. In accordance with the permission granted by the Ministry of Communication and Information with a working frequency of below 900 MHZ, mid 2.3 GHz, and high 28 GHz. One of the advantages of 5G is that the download speed reaches 20 Gpbs per user using high frequencies. This study simulates by analyzing the effect of 5G network performance when there is rain attenuation which can reduce signal quality. Then a centralized RAN (C-RAN) architectural scenario is created when the BTS is dampened by rain for each of its links. Then calculating the rainfall data to become rain attenuation with ITU-R recommendations, the SNR values are obtained from 3 dBm to 20 dBm, the SNR values are used as input using the Maximal Ratio Combining method in order to reduce signal interference that occurs due to rain.

Mushalla Al-Huda di Dusun Kapek Atas, Desa Gunungsari, Kecamatan Gunungsari, Kabupaten Lombok Barat menawarkan berbagai kegiatan seperti pengajian rutin, membaca dan menghafal Al-Quran dan masih banyak kegiatan sosial lainnya yang membutuhkan listrik untuk mendukung operasionalnya. Mushalla Al-Huda hanya menggunakan listrik dari jaringan PLN dan belum memiliki sistem listrik cadangan. Artinya, jika aliran listrik dari jaringan PLN padam, maka kegiatan diliburkan. Untuk mengatasi kondisi tersebut, pada kegiatan pengabdian ini dilakukan instalasi inverter otomatis sebagai sumber listrik cadangan. Kegiatan pengabdian ini diawali dengan pemasangan inverter otomatis yang telah selesai dilaksanakan pada 27 September 2018. Selanjutnya pada 13 November 2018, dilaksanakan pelatihan penggunaan inverter yang diikuti oleh jamaah di mushalla Al-Huda. Inverter yang telah dipasang berfungsi dengan baik seperti yang diharapkan. Dengan terpasangnya inverter pada mushalla al-huda maka kegiatan rutin mushalla seperti pengajian, baca Al Quran dan hafalan yang biasanya diselenggarakan pada malam hari, dapat tetap berjalan dengan lancar walaupun terjadi pemadaman listrik PLN.
