Abstract

Pembuatan pakan lele organik dengan bahan baku bulu ayam ditujukan untuk meningkatkan kadar protein, mengurangi biaya produksi pakan lele, mempercepat pertumbuhan ikan lele dan membuat pakan lele alternatif. Pada pembuatan pakan lele dengan bahan baku bulu ayam ini menggunakan perlakuan fisik dan kimiawi, seperti pemanasan, pengeringan, hidrolisis, grinding, dan fermentasi BIO. Perlakuan tersebut digunakan untuk mengubah protein kasar pada bulu ayam menjadi protein yang dapat dicerna oleh ikan lele. Kadar protein setelah proses perlakuan fisik dan kimiawi akan di analisa kenaikan kadar proteinnya. Dengan kadar protein yang tinggi akan membantu proses pertumbuhan lele menjadi lebih singkat dan lebih cepat panen. Untuk mengetahui kadar protein pada penelitian ini menggunakan metode kjeldahl.Hasil pakan lele berbahan bulu ayam ini akan diujikan langsung pada ikan lele untuk membandingkan perbedaan penambahan pakan lele biasa dengan penambahan pakan lele berbahan baku bulu ayam.Pada penelitian ini kadar yang paling baik pada penambahan NaOH adalah 0,4N dengan kadar protein 74,09% dan dari rantai polimer yang terpotong sangat cocok untuk pembuatan pangan lele sebelum dijadikan pelet lele.Kata kunci: bio, lele, organik, pangan, protein

Abstract

Microbial fuel Cell (MFC) has gained a lot of attention in recent years due to its capability in simultaneously reducing organic component and generating electricity. Here multicultural rumen microbes (RM) were used to reduce organic component of slaughterhouse wastewater in a self-fabricated MFC. The objectives of this study were to determine the MFC configuration and to find out its maximum capability in organic degradation and electricity generation. The experiments were conducted by employing, different types of electrode materials, electrode size, and substrate-RM ratio. Configuration of MFC with graphite-copper electrode 31.4 cm2 in size, and substrate-RM ratio 1:10 shows the best result with current density of 318 mA m-2, potential  2.4 V, and achieve maximum power density up to 700 mW m-2. In addition, self-fabricated MFC also shows its ability in reducing organic component by measuring the chemical oxygen demand (COD) up to 67.9% followed by increasing pH from 5.9 to 7.5. MFC operating at ambient condition (29oC and pH 7.5), is emphasized as green-technology for slaughterhouse wastewater treatment. Article History: Received March 26, 2016; Received in revised form June 20, 2016; Accepted June 25, 2016; Available onlineHow to Cite This Article: Prabowo, A.K., Tiarasukma, A.P., Christwardana, M. and Ariyanti, D.
