Efficacy of liquid smoke from laban wood (Vitex pubescens) against Coptotermes curvignathus. Antitermitic activities of liquid smoke produced from Vitex pubescens against C. curvignathus was evaluated in this study. This research was conducted in two steps, i.e. pyrolisis of liquid smoke and efficacy test of liquid smoke as antitermite. Three kinds of liquid smoke were produced at three different pyrolysis temperatures, i.e.  350 oC, 400 oC and 450 oC. Termiticidal activity was evaluated by a no-choice test.  The research indicates that concentration of liquid smoke and pyrolysis temperatures significantly affected  termite mortality and mass losses of the filter paper. The relationship between the concentration of liquid smoke (X) and termite mortality (Y) at 350 oC, 400 oC,  and  450 oC were Y = 31,4 + 11,76X,  (r2 = 0,60),  Y = 30 + 11,86X (r2 = 0,59),  and Y = 26,66 + 7,6X (r2 = 0,429). The relationship between concentration of liquid smoke (X) and mass losses (Y) at 350 oC,  400 oC, and 450 oC were Y= 85,12 -3,188X (r2 = 0,723), Y= 88,06 – 3,435X + (r2 = 0,953) and Y= 91,56 – 3,867X  (r2 = 0,886).

It is imperative for the Central Bank to know the current state of the economy as the basis underlying projections of future economic conditions. To that end, current economic conditions, in this case household consumption and investment, could be predicted using nowcasting. In this research, a nowcasting model was developed for the two aforementioned macroeconomic variables using a Dynamic Factor Model (DFM). Theindicators used when nowcasting household consumption included: motor vehicle sales, total deposits, the lending rate on consumer loans, M1 and the rupiah exchange rate (NEER), while the indicators used for nowcasting investment included: cement sales, motor vehicle production, electric energy consumption, outstanding loans and M1. Accuracy testing showed that the nowcasting model for household consumption using DFM was sound, while the forecast error for nowcasting investment was significant but remained below the benchmark.

The PVT technology using V-Absorber is conducted using a mathematical approach. This mathematical or theoretical approach aims to analyse suitable variables in predicting the system's optimal performance. The analysis of this system is the analysis of exergy and the most important is the analysis of the sustainability index and improvement potential. The variable values of sunlight intensity are 385 W/m 2 , 575 W/m 2 and 815 W/m 2 . At the same time, the flow air is from 0.01 kg/s to 0.10 kg/s. The analysis results show that the position of the flow air of 0.06 kg/s is the maximum value for exergy using V-Absorber. The optimum sustainability index's value was 2.012 at flow air of 0.06 kg/s with sunlight intensity of 815 W/m 2 . For the improvement potential, the optimum yield was 329.24 Watt for flow air of 0.10 kg/s. The results of the sustainability index and improvement potential analysis show that the effect of the flow air and sunlight intensity was very significant.
