Whiteleg shrimp (Litopenaeus vannamei) culture with more advanced technology has been developed in the coastal regions of Southeast Asia, including Indonesia, to catch up with the increasing worldwide demand for shrimp. If left unchecked, the effluent from this high-density shrimp farming could have irreversible impacts on the receiving environment and the shrimp industry. This study was carried out to determine changes in water quality status before and post-development of the intensive whiteleg shrimp industry in the coastal area of Je’neponto, a regency located in the south of South Sulawesi Province, Indonesia. The water quality parameters were measured in situ and ex situ before the farming cycle started and after harvesting. Temperature, salinity, pH, dissolved oxygen, nitrate, nitrite, ammonia, and phosphate were measured using standardised methods. The data were statistically analysed using Kruskal–Wallis, Mann–Whitney, and principal component analysis. Water quality status was determined using the storage and retrieval approach. The potential for waste from the intensive whiteleg shrimp ponds was estimated at 7,408 kg of total nitrogen (TN) per cycle and 1,748 kg of total phosphorus (TP) per cycle. The study also found that the wastewater treatment plant pond was only about 1.45% of the total pond volume and is classified as a low-capacity wastewater treatment plant for intensive whiteleg shrimp farming. The water quality was classified in the class B category (good or slightly polluted) prior to the operation of the shrimp farm to class C (moderate or moderately polluted) afterwards.

This article reflects on the results the use and eff ectiveness of design coding as urban design / development tool, focusing on the roles of and the relationships between the different actors playing parts in the in the design coding process: the administration, the investors, the designers, the politics and the community. It reveals the gap in professional circles that impacts the development process, which, deepened by the continuous battle between the creative, the market-driven and the regulatory modes praxis. The article is polemical in that it points to the three main parties of this collective process, referring to is as the creative, market and regulatory tyranny. The author proposes that design coding, if used correctly, could be an effective tool regulating the essentials of urbanism, leaving room for creativity and enhanced market value. Design coding as such results in improvement of the quality of both urbans space and housing architecture.
