4.5 Data Availability
Data availability is needed as an input of the system. Therefore during the research, the data capture questionnaire for industries were launched and distributed to several
industries located in Upper Citarum River Basin via the Ministry of Environment
Appendix 2, but up to now the data are still un-complete yet. As a solution, some
secondary data in the regular report 2006 is used. This condition could occur, because many perceptions from the side of stakeholders
express that there is a piling up of regular industrial wastewater raw data. Then the stakeholders are not sure whether the data can be processed without application system
quickly. Therefore, within the IWMS, the stakeholders can make process and analysis of the data, respectively. The research refers at several data as input component from many
sources, e.g.: 1

4.6 Logical Framework
The logical framework for this research can be explained by the following diagram
Figure 21. The diagram is ideal approach for problem solving in the environmental
management, especially related to river water quality and industrial waste water management. It is a complex system; therefore in this case, the system development is only
a part of the whole system as shown in the diagram. According to that framework, the first step is a looking at the existing condition
based on spatial information administration boundary, river networkstream, distribution of industry etc. for getting the data spatial and attribute, especially pollution data type and
measurement. There are two kinds of measurements based on the location. First is ambient
65
data usually from the main river – unit in mgliters and secondly is outlet data effluent from the factory unit in mgliters or kgday. Especially for effluent data, there is a need of
conversion formula from concentration form mgl, waste discharge lsecond to actual pollution load kgday.
In data collection steps, ambient data is collected by the government and outlet data by the industry or government. They are collected for several times as a general
commitment time series data. Both data can be plotted in the charts, and sometimes get result is different pattern. It means that, one of them have invalid data and need further
verification and also inquiry in the field, because actually both data should have similar pattern
.

Logical Framework of IWMS
67 In the next steps, the pollution data can be calculated by a certain method and
formulation before comparing to the quality standard Government Regulation: Ministry Degree. If the data ambient and outlet is less than quality standard, it means that the
environment still has tolerable pollution level in the Ranking terminology: Blue Green grade. Otherwise, outlet data have black or red grade industrial pollution indicators and
from ambient data the impact to environment would be determined. Starting from this condition, the monitoring and control activities can be created,
such as law and enforcement, compliance, installation of water treatment plan, cleaner production implementation, improving processing technology and so on. On the other
hand, the government has the capability also for fitting the river class A, B, C, etc. according to capacity of the river within the certain criteriaregulation. In this research, if
the condition of the river is still good accepted by stakeholders, it means that the river segment can receive the industrial wastewater disposal. If the result is fair then some
criteria and regulations are needed. It should be carefully related to wastewater disposal where, type of industry and importance. If the condition of the river is bad, the
government should provide with some protection programs. It’s a really monitoring function by the government and the final goal of this research.
Generally, the government needs a high quality spatial information to support their planning, especially to monitor the industry and also the environmental protection program.
