Abstract

Water is a vital necessity for life because without water, human and other creatures can not survive. Until now, Bu Anik’s restaurant in district Klaten has not had a system of domestic waste water treatment unit. Water pollution by waste water restaurant caused a decline in water quality in water bodies and groundwater, it is because liquid waste restaurant have a lot of organic matter. Based on this background, the research conducted to reduce waste water containing organic material by using pumice breccia as the main media. Studies using a PVC pipe 2 ½ inch amounted to four tubes with a length of 70 cm, one tube as a control while three other tubes filled with pumice breccia’s diameter is 8 mesh. Independent variable in this research that the media height between 20 to 70 cm. Pumice breccia is one of the absorbent which has binding properties of the molecules in the liquid surface. Before use pumice breccia, destroy first, in order to obtain a grain diameter of 8 mesh, washed, drying up and then hated in an oven at 200 o C for 2 hours, so that the liquid is trapped in rock can evaporate and then gives the pumice breccia’s absorption is more optimal.The result after treatment showed that the effect of the decreased levels of TSS and BOD in water samples. Average decline in media height 70 cm, from the initial sample concentration of 219.5 mg/L can drop to 85.46 mg/L (decrease efficiency 59.31 %) and for BOD at media height 60 cm, from the initial concentration 325.30 mg/L is able to drop to 63.52 mg/L (decrease efficiency 80.84%).

Abstract

Untuk mengetahui kinerja sumur minyak sebelum dilakukan optimasi digunakan perhitungan Inflow Performance Relationships (IPR) dengan luaran berupa kurva . Kurva IPR menjelaskan hubungan antara laju produksi sumur terhadap tekanan alir dasar sumur . Metode perhitungan IPR didasarkan pada fasafluida yang mengalir yang umumnya terdiri lebih dari satu fasa. Utamanya pada sumur tua dengan water cut tinggi, fasa aliran dapat merupakan dua fasa (gas – cairan) atau tiga fasa (gas – air – minyak). Selain berdasarkan pada fasa yang mengalir pemilihan perhitungan juga didasarkan pada batasan metode perhitungan. Pada beberapa sumur tua dengan water cut tinggi digunakan metode vogel karena alasan praktis, yang berdasarkan batasannya tidak sesuai digunakan pada sumur minyak tua dengan water cut tinggi. Dengan demikian ada kemungkinan optimasi yang dilakukan menggunakan metode vogel tidak dilakukan dengan tepat. Untuk mengetahui seberapa besar margin kesalahan perhitungan maka dilakukan evaluasi perhitungan IPR sumur minyak tua dengan water cut tinggi. Dimulai dengan mengumpulkan data beberapa sumur pada beberapa lapangan tua dengan karakteristik berbeda untuk kemudian dilakukan perhitungan IPR dengan metode yang sesuai (metode Wiggins dan metode linear) untuk kemudian dibandingkan dengan perhitungan IPR awal yang menggunakan metode Vogel. Dari perbandingan antara perhitungan awal yang menggunakan metode Vogel dengan metode Wiggins dan atau Linear diperoleh hasil yang berbeda dengan margin yang berbeda-beda. Hasil ini akan memberikan gambaran lebih detail pada performa sumur tua tersebut.

Abstract

Limbah plastik yang semakin meningkat menimbulkan permasalahan yang cukup serius bagi masarakat. Hal ini dapat ditanggulangi, dengan berbagai upaya, salah satunya dengan menggantikan penggunaan plastik konvensional dengan plastik biodegradable. Plastik biodegradable sudah banyak diproduksi, namun kekuatannya masih sangat kurang dibanding dengan plastik konvensional. Oleh karena itu perlu adanya inovasi dalam pembuatan plastik biodegradable yang lebih kuat. Penelitian ini mencoba untuk memanfaatkan umbi gadung sebagai bahan baku pembuatan plastik Biodegradable dan sebagai penguatnya digunakan gliserin serta serat daun nanas. Tahap pembuatan plastik biodegradable meliputi preparasi bahan (pembuatan tepung umbi gadung, dan pengambilan serat daun nanas), dilanjutkan dengan proses pembuatan plastik yaitu dengan mencampur tepung umbi gadung, larutan asam cuka, gliserin dan serat nanas, kemudian diaduk dan dipanaskan selama waktu tertentu, dan tahap terakhir adalah pencetakan serta pengeringan hasil. Penelitian dilakukan dengan variabel suhu, waktu proses, kecepatan pengadukan serta perbandingan bahan baku (umbi gadung dengan serat nanas), untuk mengetahui kondisi proses yang optimal agar diperoleh plastik dengan kuat tarik yang besar. Dengan menggunakan 10 gram umbi gadung 100 mL asam asetat 0,5% dan 2,5 mL gliserin diperoleh kondisi optimal dengan menggunakan suhu 80oC, waktu 90 menit, kecepatan pengadukan 300 rpm dan perbandingan bahan pati gadung : serat daun nanas 10:1. Dengan menggunakan kondisi tersebut diperoleh plastik dengan kuat tarik sebesar 3,8708 Mpa. Uji FT-IR (Fourier Transform Infra Red) terhadap plastik hasil penelitian ini, menunjukkan bahwa plastik hasil penelitian ini merupakan plastik biodegradable.
