Agarwood is a non-timber forest product having high economic value. However, its population in nature is getting decrease. An effort to reduce the agarwood hunting in the nature is agarwood cultivation. One of agarwood inoculation methods is simpori as a modification of inoculation method using Fusarium solani and porous nails. The present study aimed to determine the effect of F. solani dosage to the quantity and quality of Gyrinops versteegii agarwood using simpori. The simpori technique used completely randomized design with 3 treatments and 10 replications. The treatments were F. solani at a dosage of 3 mL/porous nail (P0), F. solani at a dosage of 9 mL/porous nail (P1), and F. solani at a dosage of 6 mL/porous nail (P2). The result showed that both dimensions of agarwood formation and the agarwood produced at 7 months after the first inoculation in all treatments were not significant. The highest length and the highest depth of agarwood formation were shown by P1 (5.1 cm) and P0 (7 cm) treatments, respectively. The highest agarwood production was observed in P1 and P2 treatments (0.032%). The visual quality of agarwood based on SNI 7631:2011 equal to kemedangan TG.C. The agarwood quality based on sesquiterpenes and chromone derivatives contents was different in all treatments. P2 treatment showed the highest content of sesquiterpenes and chromone derivatives (17.5%). The difference of F. solani dosages produce agarwood with the same quantity but different in quality when harvest 7 month after the first inoculation. Keywords: agarwood, phenylethyl chromone derivatives, sesquiterpenes, simpori

Maize (Zea mays L.) is one of the agricultural commodities used as food and has quite a lot of benefits. The highest Indonesian production data is found in East Java. Malang Regency is one of the highest maize-producing areas in East Java. However, the production and productivity of maize in Malang Regency has fluctuated. One of the causes of unstable maize production in Indonesia is climate change due to global warming. Climate change that affect the length of the rainy and dry season is change in rainfall patterns. The purpose of this research is evaluating whether climate change occurred in 1998-2017 in Malang Regency and to know the impact of climate change on the growing season and corn productivity in Malang Regency. The study was conducted from February to May 2018 in Donomulyo, Dau, and Kasembon sub-district, Malang Regency. The research was carried out by survey method using primary and secondary data. The results showed that the climate in the North Malang Regency had undergone a change, which was marked by the increase in rainfall and monthly temperature and changes in climate type, while in the South it was marked by the decrease in monthly rainfall, monthly rainy days, and temperatures. The elements of rainfall and rainy days do not affect maize productivity, while the temperature has a corelation and has a significant effect on the maize productivity. Temperature has a positive effect on maize productivity and a model of estimating the effect of temperature on productivity was obtained, namely Y = -38552+1836 X. The impact of climate change is the occurrence of a shift in the beginning of the rainy and the dry seasons which cause changes in the maize planting season.

The degradation of lignocellulose as the main constituents of peat is catalyzed by enzymes such as laccase or cellulase. The purpose of this research was to study the pattern of laccase and cellulase activities on sterile and non-sterile peat materials at three different water contents (125-175, 225-275, and 325-375%). The peat soil used was collected from oil palm rhizosphere in Riau Province. This research used the descriptive method by comparing the mean values between treatments. The results showed that enzymes activities on sterile and non-sterile peat added with laccase or cellulase were higher compared to those without enzyme addition. The highest laccase activity was at the first day of incubation, while that for selulase was at the 10th days of incubation. The activity of enzyme then decreased with the increase in the respected incubation time. The difference in decreasing of lignin and cellulose content at 125-175% water content was higher than at the other water contents. The decreases in lignin and cellulose contents were higher by addition of respected enzymes both in sterile and non-sterile peat. It could be concluded that at higher water content, laccase and cellulase activities were depressed both on sterile and non sterile peat, especially after the addition of enzyme.
