Abstract

CIDAT method was a waste water treatment plant which was developed to overcome waste water originated from chicken abattoir industry. The method used community-based technology approach, and was developed in Klaci II Village, Margoluwih, Seyegan, Sleman Regency. The research was aimed to study the influence of CIDAT toward the decrease of COD, TSS, and Ammonia concentration in the waste water. The study used “Pre-Test Post-Test With Control Group Design”; and the waste water sampling method was grab sampling of which three repetitions for both the treatment and control groups were conducted. As control group, the Terban chicken waste water installation was chosen. The results showed that the average decrease of COD concentration were from 1855 mg/l to 58,37 mg/l, or 98,85%; TSS: from 1597,5 mg/l to 36,5 mg/l or 97,72%; and Ammonia: from 3,16 mg/l to 0,74 mg/l or 75,81%. This results had fulfilled the corresponding regulation. The study recommend that CIDAT technology can be used to minimize the decrease in environment quality caused by the waste water, and subsequently could protect the health of people living nearby the industry.

Abstract

Motorcycle and car derived from technology development, apart from their ad-vantages as transportation vehicles are contributing to emit pollution gases such as carbon monoxide (CO) to environment. Another source for CO emis-sion is repair shop. In order to decrease CO pollution from that place, this e-mission catchment tube with double filter was developed. The tool consists of activated carbon and glass wool as the adsorbent filter agents. The study used a 100 cc 4-strokes motorcycle as the source of CO emission and auto check 974/5 for measuring the CO concentration. Both descriptively and analytically, the results showed that the tube was able to decrease the pollutant concentra-tion (p value 0,016). Howeer, it is suggested that any follow-up studies should explore the other possible material of the adsorbent, as well as the effective saturation time and the effective amount or number of the the filter.
