Abstract

Primkopal AAL Surabaya merupakan koperasi penyedia kebutuhan dari anggota AAL Surabaya. Dalam menjalankan seluruh fungsi, pengurus Primkopal AAL melakukan pencatatan data yang dimulai dari pencatatan data anggota, simpanan, penjualan, pinjaman, dan kredit. Seluruh proses tersebut dilakukan secara manual dimana hal tersebut dinilai kurang efektif dan efisien dikarenakan dalam prakteknya, membutuhkan waktu yang cukup lama saat pengajuan pinjaman dan kredit, sulitnya penyampaian informasi kepada anggota, banyaknya kesalahan pencatatan data, dan banyak hilangnya data yang disimpan oleh pengurus koperasi. Berdasarkan permasalahan diatas, penulis mengusulkan sebuah sistem yang dapat membantu melakukan penyampaian informasi dan pembukuan dari proses penjualan dan simpan bagi pihak pengurus Primer Koperasi Angkatan Laut AAL Surabaya. Sistem yang akan diimplementasikan memiliki fungsi untuk melakukan pendaftaran anggota, penjualan barang, simpanan sukarela, kredit, pinjaman, dan penyampaian informasi alur seluruh proses. Implementasi sistem akan menggunakan metode SDLC Waterfall dengan bahasa pemrograman Javascript pada framework React JS pada frontend dan Express JS pada backend dengan database MySQL. Sistem ini akan diuji dengan menggunakan metode pengujian unit testing, integration testing, validation testing, dan compatibility testing.

Abstract

Chili sauce is a sauce made using the main ingredient chili, which is processed by adding spices and permitted food ingredients, or without the addition of other foods. However, in Indonesia, the term fake sauce is often used to define sauces that contain ingredients that are harmful to the health of the body, one of the dangerous ingredients used is formalin. In checking chili sauce containing formalin carried out by experts by mixing a sample of sauce into a test tube and mixing it with a special formalin reagent, the results of the examination also require a long time. Based on these needs, it is necessary to design a system that can facilitate the checking of chili sauce containing formalin, and does not take much time in the inspection process. In this study, the detection system for chili sauce containing formalin used color parameters and formaldehyde gas content in the sauce sample. Arduino Mega microcontroller is used as a data processor on the system. The system will classify the Non-formalin and Contain Formalin data with the K-Nearest Neighbor method. In this study, 20 test data were applied in 60 training data used to determine the level of classification accuracy from the use of the K-Nearest Neighbor method with a value of K=3 of 85%, K=5 of 85%, and K=7 of 80%. Meanwhile, the average computation time obtained from 10 tests is 1807.3ms.

Abstract

Data is one of the objects in a technology that is vulnerable to attacks on cryptographic aspects of confidentiality and integrity. Attacks on confidentiality and integrity aspects can be prevented by building a data security mechanism that implements cryptographic algorithms. However, not all technologies have data security mechanisms because the devices used have limited resources. So in this study, the authors build a data security mechanism on communication between sensor nodes, gateways, and the cloud using the Chaskey-12 cipher algorithm which is suitable for devices with limited resources. The author implements the Chaskey-12 cipher algorithm with CBC operating mode in the encryption and decryption process to ensure the confidentiality of sensor data. Meanwhile, to ensure the integrity of sensor data, the author implements the Chaskey-12 cipher algorithm in the process of tag formation and tag verification. Based on several test results in this study, it is known that the sensor, gateway, and cloud nodes successfully implement the Chaskey-12 cipher algorithm and carry out their functions in securing sensor data. The test vector test results show that the Chaskey-12 cipher algorithm in this study has been implemented according to the paper of the Chaskey-12 cipher algorithm creator. The performance test results show that node sensor, gateways, and cloud require a low average execution time with a high throughput value. The security test results show that the Chaskey-12 cipher algorithm implemented by the author succeeded in guaranteeing the confidentiality and integrity aspects of the sensor data security mechanism.

Abstract

Humidity and acidity (PH) are essential factors because if rockwool is too acidic not moist or dry the plant growth rate will be slower. A pH that is too acidic or alkaline can result in the deposition of nutrients and inorganic substances in hydroponics so that plant growth is less than optimal. Temperature also plays an important role in plant growth. With this the author will create a system using a Soil Moisture sensor a PH-4502C sensor and a Linear Regression method that is connected to the Arduino Uno and will issue an output that is flowing water through a water pump with the condition that the humidity in the rockwool has not met the set point as well as for the pH will flow PHUP water if the pH conditions on Pakcoy plants are low and will flow PHDOWN if the pH conditions on Pakcoy plants are high. For this system there are 25 training data including 20 data as training data and 5 data as test data. The results obtained from the Linear Regression test are MAPE and RMSE for humidity 5,1% and 0.12 while for PH are 5,2% and 0.17 and the results of Pakcoy seed plants can grow perfectly as expected.

Abstract

MANET is a dynamic wireless network. Each node in MANET has a function as a host to connect to the wireless network and also as a router that functions to forward data packets to other nodes. In a MANET system, MANET is expected to have good performance and have a maximum level of energy efficiency. This is because each node on the MANET network requires energy to communicate with each other. In addition, the selection of propagation type can also affect of energy efficiency in MANET. In order to understand how the effect of the propagation type on energy consumption in MANET, we have conducted a study that focuses on energy consumption in MANET using two different propagation types. The two types of propagation that we used are the free space propagation type and the two ray ground propagation type. In this study, we will use the DSDV routing protocol which will regulate the routing of data transmission from the sending node to the receiving node. The DSDV protocol guarantees that there will be no looping in data transmission, so it is very suitable to be applied in this research. To achieve credible results, this study uses four test scenarios based on the number of nodes used. Each scenario will be tested 10 times using Network Simulator 2.

Abstract

Boarding rooms as a place to live should have good air quality. The most common causes of decreased indoor air quality are poor air circulation and contamination from harmful gases, one of which is carbon monoxide (CO) which is commonly found in cigarette smoke and vehicle emissions. Tool developed in this research is expected to reduce the potential dangers that may arise from high concentration of carbon monoxide gas and discomfort due to hot and humid room air. The system is designed to detect ambient air quality using the DHT22 and MQ7 sensors, and uses a fan and exhaust to control air quality. The system is built with a parameter threshold that can be reconfigured. This system is also made using a finite-state machine algorithm to define several states that represent each existing process. One of them is a deep sleep state for power saving, this is needed because the system will operate continuously, the method used is taking advantage of the deep sleep mode on the low power feature of ESP8266 chip. From the test results, it's known that this tool successfully performs its function, and is able to reduce current consumption by 34.82 mA under ideal conditions.
