Utilizing rice hulls as growing media is commonly practiced. However, it had low valued of Water Holding Capacity (WHC) and Cation Exchange Capacity (CEC) which caused rice hulls is considered as a low quality as growing media for plants. Based on previous study, pyrolysis could alter physical and chemical properties of rice hulls to form char. The aim of this study was to evaluate pyrolysis process by compare physical and chemical properties. This research was conducted at two peak temperatures (450 oC and 550 oC) with four different incubation periods (15, 30, 45, and 60 minutes). Particle size distribution, porosity, WHC, air pores, pH, and CEC values were then analyzed as the physical and chemical properties. Char resulted from pyrolysis at 450 oC with incubation period of 15 minutes produced the best physical and chemical properties among others pyrolysis treatment with dominant particle size with diameter 0.5-1 mm was 61.63 %; porosity 88.09 %; WHC 36.76 %; pH 8.57; and CEC 14.7 meq/ 100 g. It could be concluded from this experiment that pyrolysis was more effective than composting in increasing rice hulls quality as growing media for plants.

The drinking water sector is the aspect of development that has a pivotal function to support the welfare of society. This is due to health, lifestyle, residential environment conditions and comfort in daily life. The service of the piped water supply system (SPAM-JP) for the service of the capital city of Banyuwangi Regency covers 5 Subdistricts, with 44% clean water service coverage, installed production capacity of 405 liters/second and operating 330 liters/second, to service 34,319 Connection Units with customers domestic (Household) as many as 32,271 units and non-domestic as many as 2,046 units of connection. In addition, the level of continuity has not yet been achieved, this can be seen in some service areas during peak hours not flowing, besides the level of water loss is 25%. In anticipating all problems in the service, research is conducted by analyzing the technical aspects, financial aspects, and institutional aspects. In analyzing each aspect, it was used the appropriate method and updated data. The technical aspects was done by calculating water balance uses easy calk, network analysis using epanet 2.0 and determining improvement efforts. In the institutional aspects was done by the assessment of BPSPAM, while the financial aspects by analyzing the investment costs of network improvements required and alternative funding. The evaluation of existing conditions is that the production and distribution units are not optimal, in the water balance the water loss is 25%, from the HR assessment there is no activity to improve the existing HR and efforts to improve the distribution network include general improvements in the form of pipe replacement and DMA formation in all service areas and managements, namely by increasing HR and developing computer-based information systems.
