Abstract

Penelitian ini bertujuan untuk menerapkan dan mengevaluasi protokol Dynamic Mobile Ad-Hoc Network (DYMO) pada sistem monitoring lahan pertanian berbasis jaringan sensor nirkabel. Rancangan jaringan terdiri dari node sensor yang ditempatkan secara statik di lahan pertanian dan node router serta gateway sebagai node bergerak yang dibawa oleh petani/mobil pertanian. Hasil evaluasi menunjukkan bahwa protokol DYMO dapat digunakan pada jaringan sensor nirkabel untuk sistem monitoring lahan pertanian. Evaluasi rancangan dan skenario di atas lingkungan simulasi OPNET memperlihatkan kinerja jaringan menggunakan protokol DYMO dapat diterima. Salah satu pengujian memperlihatkan rata-rata delay pengiriman dan penerimaan data sebesar 10,812506/ms, minimal waktu delay end-to-end pengiriman dan penerimaan node sebesar 19,105028/ms, maksimal sebesar 19,643988/ms, dan rata-rata pengiriman dan penerimaan delay end-to-end yaitu 19,377766/ms, nilai rata-rata throughput sebesar 46.651 bits/sec. Selain itu, evaluasi awal prototip node sensor berbasis XBee pada jarak 120 meter menunjukkan kinerja jaringan seperti kehilangan paket (packet loss) dan kekuatan sinyal yang dapat diterima.

Abstract

Proses penilaian dan analisis angket terbuka secara manual membutuhkan biaya yang tinggi. Olehnya itu, penelitian ini bertujuan untuk menerapkan deep sentiment analysis pada angket penilaian terbuka menggunakan K Nearest Neighbor (KNN). Data angket yang digunakan yaitu angket penilaian perkuliahan terhadap dosen di STMIK KHARISMA Makassar yang diisi oleh setiap mahasiswa diakhir semester. Pengumpulan data dilakukan melalui wawancara dan uji coba deep sentiment analysis menggunakan Ms.Excel. Proses penerapan deep sentiment analysis dilakukan dengan mengkategorikan data uji kedalam tiga kategori yaitu: cara mengajar, waktu perkuliahan, dan harapan. Selanjutnya kategori tersebut diproses secara mendalam (deep) dengan melakukan preprocessing tanpa stemming, pembobotan kata menggunakan Term Frequence–Inverse Document Frequence, menghitung tingkat kemiripan antara data latih dan data uji, menentukan koefisien dan melakukan klasifikasi serta penetuan apakah data bermakna positif atau negatif. Evaluasi menunjukkan sistem mampu mengklasifikasikan data uji ke dalam tiga kategori deep sentiment analysis dengan hasil pengujian rata-rata tingkat keberhasilan sistem menemukan informasi sebesar 95,6%, rata-rata tingkat ketepatan sebesar 59,4%, dan tingkat harmonisasi keduanya sebesar 73,3%.

Abstract

Saat ini, jaringan sensor nirkabel merupakan teknologi yang tepat digunakan untuk pengumpulan data pertanian dibandingkan teknologi pengindraan lainnya. Sejumlah studi telah dilakukan sebagai upaya pengembangan jaringan sensor di bidang pertanian. Tetapi, jaringan sensor pada studi tersebut dikhususkan untuk jenis produk pertanian tertentu dengan pemakaian sensor yang masih terbatas, jaringan sensor dipasang dilokasi yang tidak memiliki kendala sumber energi atau tersedia infrastruktur untuk suplai energi yang memadai, serta kompleksitas desain yang diusulkan masih menyulitkan pengembang mengimplementasikannya. Penelitian ini bertujuan untuk mengembangkan jaringan sensor nirkabel sebagai sistem monitoring kondisi lahan persawahan. Prototip sistem dikembangkan berbasis platform opensource Arduino dan XBee yang mudah digunakan serta ekonomis, melibatkan tiga perangkat sensor untuk mengumpulkan kondisi lahan persawahan yaitu temperatur, kelembaban udara dan kelembaban tanah serta dirancang agar dapat digunakan dilokasi yang tidak memiliki infrastruktur energi/listrik. Evaluasi diatas lingkungan simulasi dan eksperimen yang dilakukan di lahan persawahan di kabupaten Gowa, memperlihatkan performansi jaringan yang dapat diterima. Selain itu, node sensor yang dikembangkan mampu mengumpulkan kondisi lahan persawahan secara real di lapangan dan mengirimnya ke sink/base  station untuk pemrosesan lebih lanjut.

Abstract

The diversity of capability of computers worker in distributed system influences resource allocation and completion time for each jobs on the system. This study aims to implement a dynamic load balancing technique using dynamic distribution upon demand (DDD) algorithm to optimize the resource allocation in distributed data encryption/decryption system. Evaluating was performed by comparing the proposed system with two other models that is a system without load balancing and with static load balancing method. Evaluation result showed that the resource allocation in the proposed system using DDD algorithm more optimized and at the decryption process of three and four characters with proper workload initialization values presented that the job completion time much faster than the two other systems.

Abstract

The purpose of this research is to design a low cost sensor node using ATmega328p microcontroller for monitoring a paddy field condition. Data collection techniques are done by literature study and sensor node prototype evaluation. The designed sensor node in this research consist of ATmega328P as an electronic circuit controller, DHT11 sensor to sense temperature and humidity, soil moisture sensor to read soil moisture parameter, 9V battery as power source of the node, 16MHz clock crystal to increase the microcontroller accuracy, voltage regulator to maintain a constant voltage level, and capacitor for the timer of the circuit. We use the C/C++ Arduino programming language to develop the software side of the node. The evaluation results show that the proposed sensor node is capable of sensing air temperature and humidity, soil moisture as well as send and receive the sensing data to/from the gateway node. The communication distance of the nRF24L01 module that we use for the node without an external antenna is up to 20.65 meters with an average packet loss of 20%.

Abstract

This study aims to apply the MQTT-SN communication protocol to a low-cost home security system based on the NodeMCU microcontroller. Data was collected through literature studies and experiments. The designed home security system consists of MQTT-SN client, MQTT-SN Gateway, and MQTT broker. Home security system application designed to run on Android Smartphone devices. Evaluation results of the system with a number of nodes from 2 to 10 nodes show that the MQTT-SN protocol QoS performance such as delay, packet loss, and throughput is good and acceptable. The average size of the delivery packet of MQTT-SN is smaller than that of the MQTT protocol. In addition, the designed home security system successfully sent notifications to the user's mobile device in response to the detection of movement around the sensor location points installed.

Abstract

The aim of this study is to analyze and design a sales information system using a unified approach at PT. Sapta Karya. Literature studies, observations, and interviews are performed to define specifications of the system. In the analysis phase, activity diagrams is used to model business processes of the system, use case diagrams to define functional specifications, and sequence diagrams to specify interactions between sales, warehouse, and finance departments, and class diagrams are used to establish the static structure of the system which consists of a number of entities, such as Customers, Employees, Goods, and Transactions. In the design phase, the types of attributes and methods of the class diagram are defined, and activity diagrams for modeling the application logic. The unified approach in the development of an integrated system can be applied, where each division performs its own function and communicates through data exchange between them. The designed class diagrams can be used to map the database structure and Java program code. While the logic code can be mapped from the desgined activity diagram. Evaluation of execution of the Java program shows that the functional features such as Sales Transactions can be executed and used according to the specifications.
