Abstract

Pengabdian masyarakat ini bertujuan untuk meningkatkan kualitas lingkungan perairan yang vital bagi petani udang di Sidoarjo. Dengan memberikan water quality meter kepada para petani, kami berupaya meningkatkan pemahaman mereka terhadap parameter-parameter kritis dalam air yang berpengaruh pada pertumbuhan udang. Melalui serangkaian pelatihan dan bimbingan, petani diberi pengetahuan tentang cara menggunakan alat ini untuk memantau kualitas air secara mandiri. Selain itu, kami juga menyediakan informasi dan panduan praktis dalam mengelola kualitas air secara optimal. Metode yang digunakan dalam pengabdian masyarakat ini melibatkan pendekatan partisipatif, di mana kami bekerja sama dengan komunitas petani udang untuk menentukan kebutuhan mereka dan menyusun strategi yang sesuai. Kami juga melakukan pemantauan berkala untuk mengevaluasi efektivitas alat ini dalam membantu petani mengelola kualitas air secara lebih efisien. Hasil dari pengabdian masyarakat ini menunjukkan peningkatan signifikan dalam pemahaman petani tentang faktor-faktor yang memengaruhi kualitas air untuk budidaya udang. Para petani juga melaporkan peningkatan produksi dan kesehatan udang setelah menerapkan pengetahuan yang didapat dari penggunaan alat ini. Kesimpulannya, pemberian water quality meter dan pendidikan yang terkait membantu petani udang dalam meningkatkan pemantauan dan manajemen kualitas air secara mandiri. Langkah ini dapat berpotensi meningkatkan produktivitas serta keberlanjutan usaha budidaya udang di komunitas ini.

Abstract

Vannamei shrimp is one of the leading commodities in fisheries aquaculture, due to its competitive price and the ability to be mass-produced with high stocking densities. Many coastal communities in East Java capitalize on this opportunity by engaging in vannamei shrimp cultivation. However, most shrimp farmers still measure pond water quality using conventional methods and record water quality parameters on paper, which is highly inefficient. With this issue in mind, the author sought to engage in community service by inviting representatives from the East Java vannamei shrimp farming community. The method involved delivering lectures and interactive discussions with shrimp farmers to understand their perceptions and insights regarding pond water quality, followed by the handover of modules, and subsequently evaluating the modules' usage by the shrimp farmers. As a result of this community service, we introduced a tool to assist traditional shrimp pond farmers in monitoring water quality, in the form of a "Water Quality Meter" module integrated with a website accessible via smartphones and laptops. The "Water Quality Meter" module was designed with a system to portable monitor pond water quality using Internet of Things (IoT) technology, where data obtained by microcontrollers is transmitted to a database to determine the quality value of pond water. Evaluation results indicate that farmers can use the module effectively, and data collected on the website shows that pond water quality for the farmers remains within normal ranges. Shrimp farmers directly benefit from using the module, as the shrimp pond monitoring process becomes more practical and accurate.

Abstract

Monitoring the quality of shrimp pond water is crucial for shrimp growth, with salinity being one of the most significant parameters. Currently, salinity sensors for pond water are designed for momentary measurements, which are unsuitable for continuous monitoring. This study introduces a method for continuous salinity measurement using ultrasonic signals. The proposed approach utilizes a measuring chamber equipped with ultrasonic sensors to determine the Time-of-Flight (ToF). To ensure accuracy, four ToF methods were compared, with the cross-correlation method identified as the most accurate. This method was subsequently used to calculate the ToF, which was then applied to determine the acoustic speed. Since the acoustic speed in water is influenced by salinity, temperature, and pressure, changes in salinity cause detectable changes in the acoustic speed. The acoustic speed was further used as input for the modified Del Grosso equation to derive the salinity. Experimental results showed an average error of 4.83% for saline solutions and 1.81% for shrimp pond water. These findings demonstrate that the proposed method provides sufficient accuracy for water salinity measurement.
