Abstract
Energy is a very fundamental necessity in human life. Current energy usage is highly dependent on the surrounding environment. Especially in remote areas, which require simple energy instruments such as batteries or fuel cells. The Fuel cell is an energy instrument that transfers electricity from a rechargeable source using external materials. Microbial Fuel Cell (MFC) is an alternative form of environmentally friendly energy that is commonly used as a source of energy in the future. MFC is an energy instrument that can convert chemical energy into electrical energy through catalytic reactions by utilizing microorganisms. Plant waste tofu and fishery waste is a waste that contains a lot of carbohydrates, proteins, and fats that usually cause heavy pollution to the waters. By utilizing the liquid waste itself is one way of solving problems in the environment and lack of energy by using the MFC system. For the experiment, this time aimed to compare the electrical energy generated between waste plant tofu and sewage fisheries. In a strong MFC experiment current on plant waste knows an increase as much as 1.47% of fisheries waste, while for voltages in the trial MFC waste fisheries have increased by 1.19% from tofu plant waste.

Summary
Secara umum alat dan bahan yang digunakan dalam penelitian ini adalah sebagai berikut: 1. Alat elektrolisis yang digunakan dalam sistem MFC dispreparasi terlebih dahulu sebulum digunakan.Alat eletrolisis yang digunakan adalah Jembatan garam dari tali belati. 4. Subtrat yang harus dipreparasi dalam penelitian ini terdiri dari limbah pabrik tahu, limbah perikanan tanpa glukosa dan dengan penambahan glukosa. Untuk substrat limbah perikanan 750 ml larutan glukosa di tambahkan dengan 200 ml air kemudian masukkan kepala udang dan kulit udang hingga memenuhi botol 1500 ml. 5. Elektrolit yang digunakan adalah aqudest dengan ukuran 1000 ml dalam penelitian MFC. Eksperimen MFC Pada penelitian ini, eksperimen MFC dilaksanakan dengan variasi jenis substrat, yaitu penggunaan limbah pabrik tahu dan limbah perikanan, MFC dibuat dengan menaruh dua buah chamber yang dihubungkan dengan jembatan garam. Penyajian data akan disajikan menggunakan Tabel dan grafik garis untuk memudahkan dalam melihat perubahan yang terjadi pada penelitian. Dari Tabel tersebut dapat dilihat data kuat arus dan voltase dari masing-masing limbah yang dihasilkan selama 12 jam pengambilan data.
