Abstract

Banten is one of the provinces that has a large enough production capacity of palm flour. In the production process of palm flour, waste is generated in the form of solid and liquid waste. The solid waste of the palm flour industry has been widely used by the community as animal food, while the liquid waste has not been processed at all and has the potential as a source of environmental pollutants. One of the rivers that has been polluted is the Cipager river which is located in the Lebak area, Banten. This liquid waste can be reprocessed into bacterial cellulose (nata) because it contains a C/N ratio of 15. In obtaining bacterial cellulose with the best quality, quantity, and yield, it is necessary to conduct research on a suitable medium ratio. The purpose of this study was to determine the ratio of the medium (liquid palm flour industry: coconut water) which produced the highest bacterial cellulose yield. The method used is the batch fermentation method. The stages of this research begin with depositing the liquid waste of the palm flour industry. Then filtered using gauze. After that, filter the coconut water. The fermentation medium was varied by mixing the liquid waste of palm flour and coconut water with a ratio of (500: 0) ml, (400: 100) ml, (300: 200) ml, (200: 300) ml, (100: 400) ml and ( 0 : 500) ml. The medium was heated at a temperature of 100oC and then 100 grams of sucrose was added and glacial acetic acid was added until the pH reached 4.5. Then, Acetobacter xylinum was added with a concentration of 25% (v/v). After that, it was incubated for 14 days. In this study, the highest yield of bacterial cellulose was 44.01%, namely the ratio of 500 ml of palm flour liquid waste: 0 ml of coconut water.

Additional Information:	Banten merupakan salah satu provinsi yang memiliki kapasitas produksi tepung aren yang cukup besar. Dalam proses produksi tepung aren, dihasilkan limbah berupa limbah padat dan cair. Limbah padat industri tepung aren sudah banyak dimanfaatkan masyarakat sebagai pangan ternak, sedangkan limbah cair belum diolah sama sekali dan sangat berpotensi sebagai sumber pencemar lingkungan. Salah satu sungai yang telah tercemar adalah sungai Cipager yang berlokasi di daerah Lebak, Banten. Limbah cair ini dapat diolah kembali menjadi selulosa bakteri (nata) karena mengandung rasio C/N sebesar 15. Dalam mendapatkan selulosa bakteri dengan kualitas, kuantitas, dan yield terbaik, maka perlu dilakukan penelitian terhadap rasio medium yang cocok. Tujuan dari penelitian ini adalah untuk menentukan rasio medium (limbah cair industri tepung aren : air kelapa) yang menghasilkan yield selulosa bakteri tertinggi. Metode yang digunakan adalah metode fementasi batch. Tahapan dari penelitian ini dimulai dengan mengendapkan limbah cair industri tepung aren. Kemudian disaring menggunakan kain kasa. Setelah itu, menyaring air kelapa. Medium fermentasi divariasikan dengan mencampur limbah cair tepung aren dan air kelapa dengan perbandingan (500 : 0) ml, (400 : 100) ml, (300 : 200) ml, (200 : 300) ml, (100 : 400) ml dan (0 : 500) ml. Medium dipanaskan pada temperatur 100oC lalu ditambahkan substrat berupa sukrosa sebanyak 100 gram dan ditambahkan asam asetat glasial hingga pH mencapai 4,5. Kemudian, ditambahkan Acetobacter xylinum dengan konsentrasi 25% (v/v). Setelah itu, diinkubasi selama 14 hari. Pada penelitian ini didapatkan yield tertinggi selulosa bakteri sebesar 44,01% yaitu pada rasio 500 ml limbah cair tepung aren : 0 ml air kelapa.
