RECOMMENDATION

I.	Urban Geological Environment

Information of the procedure and availability of data correspond to this study is very important to make easier in collecting data completely, so carbon dioxide emission can be estimated accurately. To make easier in achieving our objective above, we have some recommendation correspond to our experience in the field when we conducted institutional survey. Before field survey was conducted we should prepare as follows :
a.	Recommendation letter from our Institution
b.	Identify the situation and daily activity of that institute in detail where we want to visit.
c.	We should follow their interned procedure because basically the procedure for each institution is different. 
d.	Identify alternative procedure for instance illegal procedure that have been familiar there.

II.	Building Material for Urban Housing

The questionaire already contents all of necessary data and information, but for the future, there are some points need to add such as:
a.	Classification of the factories e.g small/middle/large factories that can be easily read if the notation of such classification factories is put on the cover of questionaire, especially if the number of factory is many.
b.	Column data in the questionaire is too small (narrow), needs to make it larger than it is now.
c.	Column activities is better deleted. Experienc indicated that the processing method for all factories is not  the same.
d.	The title of Global Impact Environment is better to berevised/changed by another names (one that not mention environment).

III.	Urban Building Typology

a.	Arranging the Approval Letters
There are no significant problems in arranging approval letters. It deals with the requirements and duration when proposing this letter. It is caused by different procedures in issuing approval letters for surveying amongst the institutions in both similar and different administrational authorities. It occurs when proposing an approval letter to Directorate of Social and Politics DKI Jakarta Province, which needs more or less 1 month of duration, since at other provinces need 1 days only. Other problems occur when authorized officials were not at office so the approval was delay. Therefore, the approval should be done as soon as possible in anticipating those problems.

b.	Collecting secondary data/institutional
When collecting secondary data, there should be noted which types of data and which institutions having those, so from the beginning it should be identified first whether data are available. This research activity is closely related with other activities performed by Group I. Collecting secondary data is important; data are needed to determine locations and number of samples/respondents that will be surveyed to represent population. To facilitate collecting those data is by making appointments with authorized officials to meet or to collect them. Discussing with officials at municipalities up to sub-district levels is also important.

c.	Collecting primary data/field surveys
Many things should be considered when collecting primary data/field surveys starting from developing questionnaires, time of implementing, and the surveyors who will conduct the surveys. Types of questions should also be considered. The questions must be short and clear enough for both respondents and surveyors. The questions about alternatives, which represent or accompany certain questions that hard to answer, should also be considered as well. This is done because of various abilities of respondents in understanding and answering the questions.

The surveys are recommended being done in the afternoons or holiday. At that time, respondent in particular households are commonly at home. This is done because not all dwellers knowing in detail about the activities particularly the conditions such as area and their parts. In some cases, mostly the head of households more understands than other dwellers do in understanding the detail of the houses. 

The surveyors are recommended high school graduates or higher or university students because they relatively understand the questions especially technical question, and adapt the respondents. It is needed intensive training and direction to surveyors about the questionnaires and tips that can be applied in the field so information gathered is complete enough.

Poor quality of information obtained during the surveys brings about difficulties in surveying the quantities of used building materials. Findings show that most housing have such quality. For level IV, it is possibly approached by using available design drawings with assumptions for items, which are not shown in the drawings. For Level V, it is impossible to estimate because there are no drawings that can be considered as a reference. It is required to conduct research to housings having better quality of information and statistical analysis.

For example, by collecting data about the area of brick walls for a certain type of building (e.g. type 45) for each design built by both similar and different developers. These should also be taken for all available types so it can result a graphical data expressing possible range of area of brick walls to corresponding area (types) of buildings. Those are applied for determining area of brick walls with non-standard types of buildings. It will reduce the problems due to no available information and it should be done though inaccurate as demanded.
