Abstract

The aim of this study was to reduce ammonia contamination, Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and Total Suspended Solid (TSS) in the waste water effluent of IPAL using biofilter system. The biofilter system was made of glass tubs containing filter media such as gravel, sand, and zeolite withthickness of 30 cm each. Among filter media was laid by fibers with a thickness of 5 cm. This laboratory scale biofilter system was used to conduct experiment which was design by using a simple randomized block design (RBD). The treatment experimented was the flow rate of wastewater which was consist of four levels, namely 50, 100, 150, 200 ml/min. The results showed that wastewater flow rate variation significantly affected decreasing levels of organic contaminants.The slower rate of wastewater flow haved the faster of time needed to reach steady state conditing. The optimum flow rate to reduce level of organic contaminants of domestic wastewater was 50ml/min. The effectiveness of decreasing the ammonia, COD, BOD, and TSS 91.42%, 74.77%, 52.95%, and 72.76%.

Abstract

The demand of garlics in Bali is considerably high and exceed the capability of farmers in Bali to produce garlics. Therefore garlics were supplied from other islands of Indonesia. Demand of garlics will increase along with the increasing number of population and the number of foods industry. The aims of this research were to determine the factors that affect demand and supply garlic, to analyze the stock of garlics, and policy recommendations which can be implemented to provide sufficient garlics in Bali, therefore the price will remain stable. This research was conducted in Bali Province using a system dynamics modelling, with the length of simulation period from 2012 to 2024. The research results showed the factors that affected of garlic stock in Bali were the production of garlics, demand of garlics, inter island supply and price. Further, the simulation results showed that the production of garlics in Bali wasn’t able to fulfill the demand of garlics therefore it affected the price. So, it requires inter-island supply to stabilize price and to fulfill the demand of garlics. Based on some simulation scenarios, the most effective policy could be developed in order to minimize inter-island supply and stabilize prices is through increasing garlic planting area of 35%/year and increasing land productivity of garlic plantation of 5 ton/year. Keywords: system dynamics, availability of garlic, Bali Province.
