Abstract

The purpose of making this prototype is to make a water level pemantauan tool in the dam using ultrasonic sensors and an IoT system. To support the manufacture of this tool, several other electronic components are used, including the NodeMCU microcontroller, ultrasonic sensors, water pumps, relays, and buzzers. The process of the water level pemantauan system in the IoT-based dam works as a whole. The process begins with filling water from box 1 (analogous to river) to box 2 (analogous to a dam) assisted by a water pump to fill the water box. Then the ultrasonic sensor reads the water distance data from the dam and is sent to the microcontroller and then displayed on ThingSpeak via PC / HP. When box 2 is filled with water and reaches the maximum limit, the buzzer will sound and the relay will turn off the water pump automatically. The test results show that the data obtained is accurate. When the sensor reads the water level capacity data at a distance of 6 cm, the dam capacity will be fully read, the buzzer will sound and turn off the relay automatically then send the information to ThingSpeak. Reading or pemantauan the water level in the dam can be an alternative to control the water level in the dam and facilitate the dam guard.

Abstract

Polytechnic is a university that organizesvocational education in various science and technology clusters.The learning process in polytechnic is dominated by practicumthat is 70% and 30% theory. The amount of laboratorypercentage affects the large number of laboratory. Eachlaboratory has a laboratory responsible (technician) in charge ofrecording and monitoring the completeness and condition of thepracticum equipment. Tools and materials used in the process ofpracticum is an asset and laboratory inventory that must alwaysbe maintained and checked the condition of the equipment. InUjung Pandang State Polytechnic (PNUP) in terms of assetmonitoring and practicum inventory is still done manually.Therefore need to make an application to monitor assets andlaboratory inventory, especially on campus two. It is known thatsince 2014 there are three departments that have implementedthe teaching and learning process in two campuses includingseveral laboratories have also been transferred to the twocampuses, such as electrical engineering majors, majoring inbusiness administration and accounting majors. So with thisapplication will greatly help technicians because no longer do thereporting or request tool manually and with this application inmonitoring the condition of the tool is damaged and tools thatneed further improvement more easily and can be quicklyupdated. The creation of this system begins with the needsanalysis, design design as the basis of system development, theright of access consists of technicians of each laboratory andprocurement department on campus one, content creationconsists of laboratory data, checking tools and materials, repairtools and materials and demand tools and materials then printdata laboratory

Abstract

Pengolahan gambar atau dengan istilah lain yaitu pengolahan citra telah banyak dimanfaatkan diberbagai bidang antara lain bidang Kesehatan, bidang pertanian,,dan juga untuk keselamatan hidup manusia salah satunya adalah deteksi kantuk. Deteksi kantuk ini dapat dimanfaatkan untuk pengendara kendaraan bermotor. Dalam mendeteksii seseorang mengantuk dilakukan dengan mengambil sampel citra mata berkedip per satu menit dengan memperhatikan kondisi lingkungan sekitar, factor intensitas cahaya, kualitas kamera dan ukuran proporsional. Simulasi deteksi kantuk menggunakan metode cascade classifier dan Black-White ratio. Dengan tahapan pengambilan sample citra menggunakan webcam secara real time, pembuatan simulasi program dan dilakukan pengecekan indicator keberhasilan simulasi. Diperoleh hasil kondisi mengantuk dengan jumlah kedipan sebanyak 27 kali dan tidak mengatuk dengan jumlah kedipan 7 kali dengan waktu selama 60 detik

Abstract

Sistem manajemen air merupakan bagian penting dari manajemen kota. Pengelolaan air melibatkan penyediaan air sesuai dengan kebutuhan nyata dan tanpa membuang-buang air. Oleh karena itu, sangat penting untuk mengukur laju dan volume aliran air. Sistem monitoring distribusi air (flow sensor) konvensional menuju ke pelanggan dengan mencatat penggunaan melalui metering yang ada di sisi pelanggan secara manual. Sistem pengukuran debet air (metering) secara konvensional perlu menyediakan tenaga pencatat meter ke tiap pelanggan. Pencatatan secara manual ini sering dikeluhkan dari sisi akurasi akibat kehadiran petugas yang tidak konsisten. Penelitian ini mengusulkan sistem berbasis web dengan alat meter berbasis Internet of Things (IoT). Alat meter ini menggunakan modul ESP8266 yang akan mencatat penggunaan air secara otomatis tanpa diperlukan petugas pencatat meter. Selanjutnya dari modul ESP8266 ini akan mengirimkan sinyal hasil pencatatan melalui transmisi data menuju cloud server (Blynk IoT). Metode ini diharapkan menciptakan layanan yang lebih baik  Hasil uji akurasi alat ini menunjukkan memiliki sedikit perbedaan error 5% pada hasil uji dengan satuan mL, sehingga dapat disimpulkan bahwa sistem ini mampu memberikan alternatif pencatatan meter secara tepat.

Abstract

The South Sulawesi Communication Informatics Statistics and Standardization Office is an implementer of government affairs that assists in carrying out government affairs in the fields of communication, informatics, statistics, and signage. Currently, agencies are utilizing technological developments to maximize their performance, such as the use of web servers to provide information and provide services. But of course this can cause problems such as data theft. Because of the many threats that can attack at any time. Therefore, an application is needed that can prevent this from happening. In order to overcome this, a monitoring system is implemented using the Wazuh application which is an application of SIEM. to find out how this application works in the event of an attack, testing will be carried out using 2 types of attacks, namely Distributed Denial of Service (DDoS) Slowloris and Brute Force. In this test, data will be taken in the form of application responses, namely the response time of the Wazuh application and the classification of the Wazuh application level against DDoS and Brute Force attacks which will be displayed on the Wazuh application Dashboard. Based on the test results, the wazuh application successfully detects DDoS Slowloris and Brute force attacks and can classify these two attacks at levels 3 to 10.
