Abstract

ABSTRACK  This research presents land cover conversions on Mount Tumpa Forest Park within the 2007-2014 period; what was converted, where it happened, and how big those conversions were. The results shows that there are six classes of land cover, namely secondary forest, teak forest, buses, farm fields, mixed plantation, and coconut plantation. That there were a variety of conversions between classes in all observed villages : (1) secondary forest to coconut plantation, mixed plantation, bushes and fields (5.90%), (2) mixed plantation to bushes (0.23%), (3) coconut plantation to mixed plantation (0.61%), (4) fields to mixed plantation, bushes and secondary forest (4.74%). Even though some areas classified as bushes and farm fields were converted into secondary forests, the conversion of secondary forests to other classes (coconut plantation, mixed 2  plantation, bushes, and fields) is bigger in comparison, thus causing a decrease of the forest area by 1.03 ha.Or  175.13 to 174.10 ha between 2007-2014.   Keywords: Forest area decrease, land cover conversion, GIS

Abstract

ABSTRACT  This research studied the effects of planting media on the growth of red Jabon (Anthocephalus macrophyllus (Havil) Roxb) seedlings. The objective was to determine the effect of several mixtures of soil, sand, and manure as a planting media for growing seedlings of red Jabon. The research was conducted in two months from April to July 2013, using a completely randomized design (CRD). There are 5 treatments of planting media, namely M1, M2, M3, M4, and M5. Each treatment has 5 replications and each replication was planted with one individual plant. Measured variables were plant height, trunk diameter and leaf number Analysis of variance was done and if there was a significantly different among treatments, a folowing LSD test was carried out. Increments of plant height were significantly different at 63 day after planting,(DAP) whereas increments of trunk diameter were significantly different at 49 DAP. Mixtures of soil, sand and manure showed significantly different effects, and adding sand to the soil with relatively high clay content (> 40%) was important to improve air and water circulation in planting media.
