Abstract

Electricity consumption expands every year. However, in Indonesia, electricity is still highly dependent on conventional energy sources such as coal. A microbial fuel cell (MFC) is one of the alternative inventions that consists of a series of tools which converts chemical energy into electrical energy in the presence of microbial metabolism. In addition to produce electrical energy, it may also help to solve environmental issues by dealing with waste. This research was purposed to investigate the potency of Chinese food restaurant waste as substrate to generate electricity in microbial fuel cell. The research was done in three stages: wastewater preparation, assembly of MFC tools in various circuits, and running MFC processes. Results showed that the best electrical average (1.02 V) was found in the treatment system without active sludge. The best circuit was in the system in 4 series, which obtained a maximum voltage of 3.76 V and the largest power density of 62.66  mW/m2. In addition, with the addition of active sludge, biological oxygen demand (BOD) of the wastewater could be lowered up to 29.27%, and chemical oxygen demand (COD) up to 51.58%. Total suspended solid (TSS) could be decreased up to 49% on the sample withoud sludge addition.

Abstract

Penelitian ini dilatarbelakangi oleh bahasa yang digunakan dalam cerpen termasuk fenomena kebahasaan yang bersifat deiktis. Fenomena deiksis dalam cerpen dapat berupa kata ataupun ungkapan yang mengandung referen dan berpindah-pindah. Penelitian ini bertujuan untuk untuk memperoleh deskripsi bentuk dan fungsi deiksis dalam cerpen terbitan surat kabar Kompas Edisi Desember 2021. Desain penelitian ini adalah kualitatif deskriptif. Metode dan teknik pengumpulan data menggunakan metode simak dan teknik catat. Metode dan teknik analisis data yang digunakan adalah metode padan referensial dengan teknik Pilah Unsur Penentu (PUP) serta Hubung Banding Menyamakan (HBS). Sumber data penelitian ini adalah cerpen surat kabar Kompas Edisi Desember tahun 2021. Data dalam penelitian ini berupa morfem, kata, frasa, maupun kalimat yang mengandung deiksis. Hasil penelitian menunjukkan deiksis persona, deiksis ruang, deiksis waktu, deiksis dengan pemarkah anafora, dan deiksis dengan pemarkah katafora. Bentuk-bentuk deiksis yang ditemukan adalah bentuk berupa morfem, kata, dan frasa yang memiliki fungsinya masing-masing sesuai dengan konteksnya.Kata kunci: bentuk dan fungsi, cerpen, deiksis, pragmatik, surat kabar kompas.
