Kualitas air dapat menurun dengan cepat karena terjadinya pengendapan sisa pakan, feses, dan buangan metabolisme pada ikan yang menyebabkan konsentrasi fosfat meningkat sehingga air menjadi keruh. Selain itu, perubahan pH yang besar dalam waktu singkat menimbulkan gangguan fisiologis bagi ikan. Kualitas air akuarium memegang peranan yang penting dalam pemeliharaan, sehingga diperlukan sistem yang dapat mengontrol dan memantau kualitas air pada budidaya ikan. Penelitian ini bertujuan untuk merancang dan membangun sistem kontrol pH dan turbidity akuarium serta mendapatkan kinerja hasil rancangan. Perancangan sistem yang dihasilkan pada penelitian ini meliputi penggunaan Arduino Uno ATmega328P sebagai mikrokontroler yang terhubung dengan sensor pH E-201 BNC sebagai pengukur pH, sensor turbidity SEN0189 sebagai pengukur kekeruhan, sensor ultrasonik sebagai pengukur ketinggian air, relay sebagai pengendali pompa dan solenoid valve, serta LCD 16x2 sebagai pemantau. Sistem menggunakan setting point pH dan turbidity untuk ikan koi yang dimasukan secara manual melalui coding. Sistem yang dibangun menghasilkan prototipe akuarium dengan dimensi 40cmx25cmx28cm yang dilengkapi oleh sensor pH E-201 BNC dengan error pada larutan asam, basa, dan netral sebesar 0,35%, 0,72%, dan 0,49% serta akurasi sebesar 99,65%, 99,28%, dan 99,51%, sensor turbidity yang sudah dikalibrasi dengan TDS meter, serta sensor ultrasonik HC-SR04 dengan error sebesar 0,53% dan akurasi sebesar 99,47%. Sistem berhasil membaca, menampilkan data, dan memberikan output dengan response time pada sistem pengurasan dan pengisian sebesar 6,3s dan 0,14s. Sistem dapat bekerja dengan baik dimana sistem dapat memantau dan mengontrol pH dan turbidity dalam akuarium. \u0000Abstract \u0000Control systems are widely applied in various fields, including fish farming. Water quality can decrease rapidly due to the deposition of feed residues, faeces, and metabolic waste of fish. The deposition causes the phosphate concentration to elevate; as a result, the water becomes murky. In addition, significant changes in pH in a short time cause physiological disturbances for fish. Aquarium water quality plays a vital role in the maintenance of aquarium fish; therefore, a system that can control and monitor water quality in fish farming is needed. The purpose of the study was to design as well as build an aquarium pH and turbidity control system and to assess the performance of the design produced. The system was designed using Arduino Uno ATmega328P as a microcontroller. This microcontroller was connected to sensor pH E-201 BNC, sensor turbidity SEN0189, ultrasonic sensor as a water level sensor, a relay as a pump controller, solenoid valve and 16x2 LCD as a monitor.

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perbedaan suhu dan jenis kemasan plastik (PP dan PE) terperforasi terhadap kesegaran buncis untuk mendapatkan perlakuan terbaik. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor perlakuan. Faktor pertama yaitu suhu penyimpanan dan faktor kedua yaitu jenis kemasan. Faktor pertama terdiri dari suhu 6 ?, 8 ?, dan 10 ?. Faktor kedua terdiri dari jenis kemasan plastik PP dan plastik PE dengan 8 jumlah lubang terperforasi berdiameter 5 mm serta ukuran plastik 11,4 cm x 24 cm yang disimpan selama 15 hari.

Kind of the effort to inhibit the process is the application of edible coating. This study aims to the sesame oil and lemongrass oil effect as edible coatings with the best concentration of sesame oil and lemongrass oil on the characteristics of the fruit salak gula pasir during storage. The study used a complete randomized design (RAL) factorial with two factors. The first factor is sesame oil treatment on three concentration levels of 0%, 0.5%, and 1%. The second factor is the lemongrass oil emulsion treatment on four concentration levels of 0%, 0.5%, 1%, and 1.5%, and additional control treatment stored at room temperature 27 ± 3 °C. Every treatment was repeated three times, with a storage length of 10 days.
