Abstract

Oil and water are two liquids that are often usedby both the public and industrial companies. Mixing oil and water need to be separated in various industries such as waste processimg, oil and gas production, and other industrial processes. Hydrocyclone is a separation method with the principle of sparation based on specific gravity which utilizes centrifugal fore by adding a bubble generator to the input section and adding variations in the underflow diameter. This research aims to analyze the performance of a hydrocyclone bubble generator based on underflow variations as oil-water separation. This bubble generator is used to make it easier to suck in air. The variations in underflow diameter used are 10mm, 15mm and 20mm. This research was carried out inject a mixture of oil and water into a hydrocyclone system as a sparation medium. The air flow injeted into the bubble generator uses air flow variations of 0.1, 0.6 and 1.2 lpm (liters/minute). From the research that has been carried out, the results show that the larger the underflow opening, the greater the pressure in the underflow, so that the underflow pressure drop is greater. The smaller the underflow opening, the greater the overflow pressure, so the overflow pressure drop is greater. The greater the input air flow, the greater the difference in underflow and overflow pressure drop. The smaller the valve opening, the lower the efficiency of oil separation in overflow and the greater the efficiency in underflow. The highest efficiency results on overflow are 88.6%.

Abstract

Umbi Porang merupakan salah satu komoditas ekspor di Indonesia. Masing-masing wilayah di Indonesia bersaing untuk melakukan penanaman porang. Salah satu Kelompok tani Desa Kembiritan Banyuwangi merupakan penghasil umbi porang. Kelompok tani memanen umbi porang dan mengolahnya setelah itu dikirimkan ke berbagai kota yang ada di dalam negeri maupun ke luar negeri dalam bentuk chips porang karena memiliki harga jual yang cukup tinggi. Minimnya pengetahuan masyarakat terhadap teknologi untuk pengolahan tanaman porang menjadi chips porang mengakibatkan produktivitas chips porang kurang maksimal. Hal itu juga menyebabkan biaya produksi semakin tinggi. Berdasarkan permasalahan tersebut, dibutuhkan sebuah penerapan IPTEK untuk mengatasi masalah kurang optimalnya produktivitas chips porang. Proses penanganan pasca panen yang cepat dan benar dapat menghasilkan chips yang mempunyai mutu baik, mengurangi kehilangan bobot, mengurangi nilai kamba, dan memperpanjang umur simpan. Penerapan teknologi Porang Bulb Chopper Machine With 2 Hoppers diawali dengan penyesuaian teknologi dengan kebutuhan mitra kemudian dilakukan tahap analisa dan evaluasi teknologi. Hasil dari evaluasi dengan menggunakan penerapan teknologi tersebut 55%.
