Abstract

Teknologi telekomunikasi saat ini menuntut penggunaan data rate yang tinggi dalam proses pengiriman data. OFDM merupakan teknologi multiplexing yang didasarkan pada penyebaran data yang dimodulasikan pada kecepatan data rendah. OFDM memiliki keunggulan tahan terhadap multipath delay spread, frequency selective fading, serta modulasi dan demodulasi yang efisien. Penelitian ini bertujuan untuk mengetahui karakteristik BER dan PAPR terhadap SNR dan mengetahui perbandingan kinerja teknik modulasi QPSK, 16-QAM dan 64-QAM. Penelitian dijalankan dengan melakukan simulasi pengiriman citra melalui kanal Rayleigh Fading menggunakan modulasi QPSK, 16-QAM, dan 64-QAM. Parameter SNR yang diteliti sebesar 0-16 dB. Hasil simulasi menunjukkan bahwa OFDM memiliki ketahanan noise yang lebih tinggi saat menggunakan modulasi 16-QAM dengan BER = 0 dB saar SNR 10 dB dan rata-rata nilai PAPR yang semakin meningkat dari SNR 0 dB hingga 16 dB.

Waste is waste that is caused by human activities and consumption. Garbage has become an old problem faced by cities in Indonesia, including the town of Jember. The small business group BAROKAH and FAIQ JAYA are small business groups engaged in the collection of used goods (waste) in the Ambulu and Jenggawah Districts of Jember Regency, which consist of garbage collectors. The types of used products that are accommodated are non-organic waste such as scrap metal, waste/paper, and plastic waste, where the plastic trash and other garbage are collected, and recycling processes can still increase the selling value. This activity aims to increase the value of selling products, income, and knowledge of small business groups as activity partners. The plan for this activity is carried out by holding a plastic garbage crusher, a special cart of chemical, organic waste, and training activities in waste management, garbage utilization training, operational training tools, and equipment maintenance training. The method of implementing this activity is field observation, socialization, discussion with activity partners, designing and manufacturing tools (plastic garbage crusher and organic / non-organic carts, waste management training, waste utilization training, operational training tools, tool maintenance training, and monitoring evaluation of activities. From this activity 1 (one) unit of plastic waste crushing machine has been produced to increase the selling value of plastic waste, 2 (two) groups of organic / non-organic waste bins to streamline the garbage collection process, the activity partners have received training-training waste management, waste utilization training, operational training tools, and tool maintenance training, so that knowledge of increasing product selling value and partner income can increase.

Abstract

An IoT-based monitoring system is a system that can monitor the situation by utilizing an internet connection. This system can be applied to simplify a production process, for example monitoring the results of the storage of coconut sap. Nira is a liquid from coconut flowers which has a sugar content ranging from 7.5 to 20%. The way to get sap is to climb a coconut tree and put the container on top, then wait for the container to fill up with sap. The monitoring process can be simplified by utilizing IoT technology. There is a sensor installed in the container, namely a water level float sensor which functions as a sensor to monitor the results of the storage of sap. The sensor provides information to the user via the eps8266 electronic board and LoRa module. Information can be read by users through the telegram application. The results of the test show that the water level float sensor can detect coconut sap that has filled the container. The use of the LoRa SX1278 module is effective in plantation areas. The signal capture power is good even though it is placed on a coconut tree where there are several obstacles that block around the module.

Abstract

Kina in plants there are several kinds of plant parts that can be taken advantage but in this case, the author will discuss the special problems of cinchona bark between 0.5 meters and 0.5 meters from the bottom and top of the plant kina. Because the bark of cinchona was the producers took to be resold to the pharmaceutical industry. During this time many of the manufacturers of leather kina kina dry the skin by way menjemuran directly in the sun. In this process the skin needs time producers such as 5-6 days if no disruption of nature such as rain, clouds, etc.. For example, if there is rain then the drying process can take up to 2 weeks up to maximum water levels dropped to 60% - 55%. With the above problems the writer needs to design a device where the temperature can be controlled and not influenced by disruption of natural factors.

Abstract

Kemajuan teknologi berkaitan erat dengan efisiensi manusia dalam melakukan pekerjaannya, salah satunya adalah pada sistem perparkiran. Semakin tinggi frekuensi kendaraan yang keluar masuk suatu tempat parkir akan memungkinkan komputer untuk menggantikan peran manusia dalam melakukan pencatatan plat nomor kendaraan. Pada penelitian ini akan dibuat suatu sistem yang dapat mengenali plat nomor secara otomatis dan memiliki sistem keamanan terhadap data plat nomor itu sendiri. Sistem pengenalan plat nomor pada penelitian ini menggunakan metode template matching. Pengambilan data dilakukan pada siang dan malam hari untuk mengetahui pengaruh tingkat intensitas cahaya terhadap kinerja sistem. Pada pengambilan data siang hari, dari 10 citra uji terdapat 9 citra yang teridentifikasi dengan benar (akurasi 90%). Sedangkan pada malam hari, dari 10 citra uji terdapat 8 citra yang teridentifikasi dengan benar (akurasi 80%). Sehingga, total akurasi sistem dalam melakukan proses identifikasi adalah sebesar 85%. Pada proses keamanan data, citra yang telah teridentifikasi (dalam hal ini sebagai plainteks) akan dienkripsi menggunakan algoritma kriptografi hill cipher. Dari 20 data plainteks, terdapat 20 data yang terenkripsi dengan benar, dengan kata lain akurasi algoritma kriptografi hill cipher pada sistem adalah 100%. Kata Kunci: citra, identifikasi, plat nomor kendaraan.

Abstract

Low Power Wide Area Networks (LPWAN) applications are a major concern in infrastructure. Rural are areas that have a poor quality signal; the cause lies in the location of the rural regions away from the coverage area Base Transceiver Station (BTS) so that the need for telecommunications equipment in the form of Global System for Mobile communications (GSM) repeaters. GSM repeater devices require an antenna that has a large gain mainly on the receiving antenna, one antenna that has a large gain character is helix axial mode has a large dimension resembling a spring and has a directional radiation pattern properties, whereas the antenna with an omnidirectional radiation pattern is a patch meander line antenna has compact dimensions and is easy to fabricate. The meanderline patch antenna has the disadvantage one of which is the small gain caused by trapped surface waves on the ground. This research will discuss the design and realisation of helix axial mode, and patch meanderline Defected Ground Structure (DGS) for Low Power Wide Area Networks (LPWAN) application in a rural area so it can be used for Internet of Things (IoT) based weather monitoring. Integrating antenna helix axial mode as receiving antenna and antenna patch meanderline DGS as rebroadcast antenna in GSM repeater able to make edge network in a rural area become High-Speed Packet Access + (HSPA +) network. The test result IoT based obtained the value of Received Signal Strength (RSSI) an average of -89 dBm in HSPA+ network.
