Aquaponics is the combined cultivation of fish in aquaculture systems and plants in hydroponic systems. This study aimed to explore and evaluate new aquaponics system designs in Jakarta, Indonesia, in terms of water and nutrient efficiency, and/or profitability. In total, one brackish water system with barramundi and tomato (BW) and three freshwater systems with Nile tilapia, rice, and duckweed (FW + DW), Nile tilapia and rice (FW − DW), and Nile tilapia and tomato (FW-tomato) were investigated using dynamic mathematical models. The results showed an increase of N, P, and water use efficiency by 10%, 18%, and 31%, respectively, in FW-tomato compare to FW − DW. Meanwhile, FW + DW only slightly increased the efficiency but worsened the already negative net present value (NPV) of FW − DW due to the high land prices. The BW system had similar water and nutrient efficiency to FW-tomato, but lower NPV. Profit of the BW and FW-tomato becomes comparable if the hydroponic area in the BW system can be expanded by 35%, or the selling price of tomato or fish in the BW can be increased by 20%. Given the expected growth of both the production of tomatoes and aquaculture in Indonesia, there is potential for further introduction of aquaponics systems in Indonesia.

This study entitled Markedness Realization in Everything, Everything Movie Script. The research is meant to analyze how the Theme markedness realized in the clauses of the movie script. The theory that is used in this research is Systemic Functional Linguistics (SFL) proposed by Halliday (1994), regarded with textual function that observes clause as a message and analyzes it from the thematic structure in the term of Theme-Rheme. He states that Theme can be divided into two, unmarked Theme is an element that occupies the point of departure position of the clause, conflating with the grammatical subject and marked Theme is an element other than occupies the point of departure position of the clause, but does not conflates with the grammatical subject. The method that is applied in this research is descriptive qualitative method. The source of data were one of the most viewed romantic movies in 2017 script, Everything, Everything, taken from Springfield Springfield site. Data of the research were selected, based on the second character dialog of this movie script. The purpose of this research is to indicate the four types of markedness and to describe the realization of the Theme markedness in the movie script. The research findings showed that the dominant type of markedness realization is simple unmarked Theme with 69.4% percentage. This type of markedness dominated other kinds of markedness realization in addition to simple marked Theme with 2.4% percentage, multiple unmarked Theme with 27.1% percentage, and multiple marked Theme with 0.9% percentage.
