Published: April 2020

Abstract
The large contribution of inflation in the food group influences the dynamics of economic growth in Indonesia, especially in Pematang Siantar City. The increase in commodity prices causes a decline in the value of the currency so that the purchasing power of society is low. This is because in real terms the level of community income decreases. Thus, the researcher wants to examine the effect of fluctuations in monthly food commodity prices in Pematang Siantar City from January 2013 to December 2017. The analytical tool used is the VAR analysis. The results, it can be concluded that in the short term two variables affect inflation at i.e. inflation and rice. Whereas in the long-term, five variables influence inflation, namely rice, chicken, red chili, cooking oil, eggs, and corn. In the short, medium and long term, a large response to inflation is the red chili difference. Every time a standard deviation occurs, the shock of red chili will be responded to by inflation until it rises 0.164180 (short-term), 0.139068 (medium-term) and 0.139071 (long-term). Then the most dominant in explaining the diversity of inflation is red chili and purebred eggs.

Published: April 2020

Abstract
In general, particleboard has a weakness in terms of low dimensional stability. This study aims to analyse the effect of immersing wood shavings in a mixture of acetic acid (AAc) and acetic anhydride (AAn) solution at several ratios to properties of particleboard. Wood shavings were immersed in an AAc/AAn solutions for 24 hours with a concentration of AAc 3% and AAn 2% with a mixture ratio of AAc / AAn consisting of 100/0, 80/20, 70/30. The boards made with a thickness and density target of 10 mm and 0.75 g/cm3, respectively. The pressing was carried out at 130°C, pressure 30 kg/cm2 and the time was 10 minutes. Testing of board properties refers to the JIS A 5908 (2003). The results show that acetylation treatment on wood shavings reduces the thickness swelling value. It was an indication that there had been an improvement in dimensional stability. An increase in the proportion of AAn resulted in a decrease of thickness swelling, water absorption, and moisture content of particleboards. On the internal bond, increasing the AAn proportion in the AAc/AAn solution further decreases the value of an internal bond, however overall internal bond value of board in this research meets the standard.

Published: April 2020

Abstract
Caffeine is considered as an important quality indicators of coffee. Caffeine content in green coffee bean influence the flavour and price of coffee. Commonly, percentage of caffeine content is determined by chemical method, which is known time consuming, destructive and expensive, so it is not suitable for a real time coffee content prediction system. The objective of this study was to develop a PLS model based on NIR-Spectroscopy to predict caffeine content of Indonesia coffee beans nondestructively. The wavelength used in this study was 1000-2500 nm and the caffeine content of samples were determined by LCMS method. Several data pretreatments such as multiple scatter correction (MSC), first derivative (dg1), combination of dg1+MSC, with PLS factors variation were applied to obtain the best prediction of caffeine content by NIR. The best prediction was obtained using MSC and 6 PLS factors indicated by a high coefficient correlation value which was >0.9. NIR method can be used for predicting the caffeine content of green bean coffee nondestructively.
