What is it about?
A water quality monitoring system for vannamei shrimp cultivation based on the internet of things (IoT) can use sensors to measure parameters such as pH, temperature, water level, salinity, dissolved oxygen, and turbidity. The data collected can be displayed offline using an LED matrix P10 and online through MQTT Broker and ThingsBoard.

Why is it important?
The results of the overall system test in the Monitoring section, namely sensor data in the form of pH, temperature, height, salinity, dissolved oxygen, and Turbidity can be displayed according to functions offline using the LED matrix P10. And can be displayed online on MQTT Broker and thingsboard. In the WiFi test, the signal quality does not affect the time and data transmission from the master to the LED matrix P10 and the Actuator Node. However, signal strength affects sending data from the master to the MQTT broker, where at an average RSSI strength of -88.7 dBm two sensor data are not sent. And when the WiFi signal does not affect the time and data transmission from the master to the LED matrix P10 and the Actuator Node, it does affect data transmission from the master to the MQTT broker where no data is sent.
Perspectives
Writing this article is very enjoyable because it allows me to learn more about the use of internet of things technology for monitoring the cultivation of vannamei shrimp ponds.

Sistem Kontrol dan Monitoring Kualitas Air Tambak Udang Windu Dengan Metode Fuzzy Logic Control Menggunakan Mikrokontroler NI myRIO
Kualitas air tambak merupakan faktor yang sangat penting untuk kelansungan hidup dan produktivitas budidaya udang windu. Kualitas air tambak yang baik dapat dilihat dari parameter fisika yaitu suhu air, salinitas, dan kekeruhan air. Buruknya kualitas air dapat menyebabkan menurunnya nafsu makan udang, penggemukan udang menjadi lambat, dan mudah terserang penyakit. Untuk menghindari masalah-masalah tersebut, penulis mengusulkan sebuah sistem embedded yang dapat melakukan monitoring dan kontroling kualitas air tambak berdasarkan parameter suhu, salinitas dan kekeruhan air. Pengontrolan dan monitoring menggunakan mikrokontroller NI myRIO-1900 dengan metode Fuzzy Logic Controller. Selain itu, sistem ini juga dapat menyimpan hasil data monitoing dan kontroling yang telah dilakukan. Berdasarkan hasil pengujian yang dilakukan, sistem dapat melakukan monitoring terhadap suhu, salinitas dan kekeruhan dengan rata-rata waktu stabil 241.67 detik. Untuk penentuan kualitas air tambak menggunakan metode Fuzzy Logic Controller dengan tiga membership dan lima membership yang dibandingkan dengan perhitungan manual memperoleh hasil fuzzy dengan lima membership jauh lebih akurat dengan perbedaan 0.51, sedangkan fuzzy tiga membership menghasilkan perbedaan 3.22. Fungsi pengontrolan kualitas air tambak dengan mengontrol putaran pada pompa air (PWM) menghasilkan tingkat kesesuaian yang baik. Abstract The water quality is a very important factor for the survival and productivity of shrimp farming. The water quality can be seen from the physical parameters of water temperature, salinity, and turbidity. Poor water quality can lead to decreased appetite of shrimp, slow fattening, and susceptible to disease. To avoid these problems, the authors propose an embedded system that can monitoring and controlling the shrimp farm water quality based on temperature, salinity and water turbidity parameters.Microcontroller NI myRIO-1900 with fuzzy logic controller methode are used to control and monitor the water quality of shrimp farm. This sistem can also store the results of monitoring and controlling data that has been done. Based on the test, the sistem can monitor the temperature, salinity and turbidity with an average time stable 241.67 seconds. For determination the shrimp farm water quality using Fuzzy Logic Controller method with three membership and five membership compared to manual calculation obtained fuzzy result with five membership is much more accurate with difference 0.51, while fuzzy with three membership yield difference 3.22. on the water quality control function by controlling the speed of the pump rotation produce a good level conformity.
Desain Sistem Pemantauan Kualitas Air Pada Perikanan Budidaya Berbasis Internet Of Things Dan Pengujiannya
Memonitor kualitas air pada perikanan budidaya sangatlah penting. Hal ini terkait dengan upaya mengoptimalkan pertumbuhan ikan dan meningkatkan hasil produksi. Umumnya kegiatan ini dilakukan secara manual, yaitu dengan mengambil contoh air kolam pada pagi, siang, dan malam hari, lalu hasil pengukuran di analisa. Hal ini sangat tidak efektif. Sehingga pada penelitian ini, kami merancang sistem pemonitor kualitas air yang dapat memastikan kondisi air secara real time, memeriksa nilai parameter melalui Smartphone, dan menerima pemberitahuan alarm jika terjadi perubahan nilai diluar rentang nilai yang telah ditentukan.Sistem ini terdiri dari tiga bagian yang saling terintegrasi yaitu (1) empat sensor yang penting dalam pertumbuhan ikan yaitu, DO, suhu, pH, dan salinitas; (2) RTU berbasis mikrokontroler ESP32 dan ADS115 sebagai kontroler dan ADC; (3) Blynk sebagai display pemonitoring nilai parameter yang berbasis Internet of Things. Hasil pengujian menunjukkan bahwa sistem ini dapat berfungsi dengan baik. Alarm berbunyi dan notifikasi alarm terbaca di smartphone apabila nilai parameter diluar rentang yang telah ditentukan.
DINAMIKA DAYA SAING EKSPOR UDANG BEKU DAN OLAHAN INDONESIA DI PASAR INTERNASIONAL
During the past eleven years, shrimp is the leading commodity of Indonesian fishery exports, especially the types of frozen and preserved shrimp that have a considerable export value. However, Indonesian exports value growth of both shrimp products are lower than its competitors. The purpose of this study is to analyze the level of competitiveness and the exports dynamics position of frozen and preserved shrimp in Indonesia among competing countries in the international market. The method used is Revealed Comparative Advantage (RCA) and Dynamic Revealed Comparative Advantage (DRCA). The method is used to analyze changes in the competition level for 11 years (2007-2017), which is divided into 2 periods namely 2007-2012 and 2012-2017. The results showed that both frozen shrimp and preserved shrimp had a competitiveness in the international market. The competitiveness of Indonesian preserved shrimp tends to increase among 9 main competitors in two periods. In the first period, the competitiveness of Indonesian preserved shrimp was in the falling star position while in the second period reached the best position, namely rising star. On the other hand, the competitiveness of Indonesian frozen shrimp position in the first period was in the lost opportunity and reached the rising star position in the second period. Indonesia needs to increase exports of frozen and preserved shrimp products by ensuring the availability of raw materials and improving quality in exporting frozen shrimp and preserved shrimp.
