Abstract

The objective of this research is to determine the rare earth elements (REEs) from themonazite minerals content of several tin tailing sands (TTS)of ex-tin mining area in Kuala Raya Singkep Island, Indonesia. We used the energy dispersive analysis of  X-ray (EDAX)-scanning electron microscopy (SEM) and x-ray diffraction (XRD) to characterize the contents of the samples. The coupled analytical of XRD with SEM/EDX approach enabled to be used for mineralogical identification on the heavy mineral as a rapid determination approach. The analysis of the samples indicates only the presence of REEs including lanthanum (La), cerium (Ce), and thorium (Th) are consistent with the identification of monazite and minerals in the tailing sand. The results show that the average REEs consist of La at 0.2 .%, Ce at 7.8 %, and Th at 2.0% respectively. It is concluded that monazite minerals in TTS has an economic potential to be developed. These monazite minerals can be used as material for semiconductor devices.

Abstract

One potential plant species for restoration in peat swamp forests is Cratoxylon arborescens. A well-managed nursery includes the application of chicken manure. This study aims to determine the effect and best dose of chicken manure fertilizer on the growth of Cratoxylon arborescens seedlings on peat planting media. This research used RAL (Completely Randomized Design) experimental method, which consisted of 4 treatments (P0 = control, P1 = 10% chicken manure + 90% peat, P2 = 30% chicken manure + 70% peat and P3 = 50% chicken manure + 50% peat) with 5 replications. The data obtained were analyzed statistically using variance analysis, followed by Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results showed that chicken manure had a significant effect on the growth of Cratoxylon arborescens seedlings, because it was able to increase fertility and nutrient availability, improve the physical, chemical and biological properties of peat. The most effective and best treatment for four-month-old Cratoxylon arborescens seedlings was P2 (30% chicken manure + 70% peat) with 100% survival percentage, average height increase of 14.39 cm, average diameter increase of 1.56 mm, dry weight of 7.41 g and seedling robustness of 8.35

Abstract

Shorea leprosula is one of the most important commercial timber in Indonesia. The existence of this red meranti plant is included in the IUCN Red List with an endangered conservation status. Efforts to increase the productivity of red meranti plants can be done by improving the quality of the planting media and increasing the growth of seedlings. This study aims to determine the effects and the best composition of planting media and chicken manure on the growth of red meranti seedlings. The research was conducted at the Experimental Garden and Forestry Laboratory, Faculty of Agriculture, University of Riau. The method used in this research is a completely randomized design (CRD) factorial pattern consisting of 9 treatments and 3 replications so that 27 experimental units were obtained. The first factor is the concentration of planting media (B) consisting of 3 levels, namely: peat (B1) = 100%, minerals (B2): 100%, combination of peat + minerals = 50% + 50%. The second factor is the concentration of poultry manure (P) consisting of 3 levels, namely: P1 = 10%, P2 = 20%, P3 = 30%. The results showed that the combination of peat and mineral (B3) planting media significantly increased the height of red meranti seedlings with an average of 0.731 cm and a root crown ratio of 3.972. The treatment of poultry manure had no significant effect on the observed parameters of the red meranti seedlings. The best treatment combination was found in the B3P2 combination with an average increase in height of 0.860 cm, diameter increase of 0.089 mm, dry weight of 5.190 g, root crown ratio of 4.770.
