Abstract

Pine trees (Pinus merkusii Jung et de Vresie) are one type of plant that is widely used in reforestation and industrial plantations. In addition, Pine is also one of the types of forest plants that have multiple benefits because in addition to producing wood it also produces sap that can produce gonderukem and turpentine. Utilization of non-timber forest products, especially tapping pine resin in Namo Village has not been done optimally. To find out how much the production of pine sap is produced with certainty, a research is conducted on the amount of pine tapping production in Namo Village, Kulawi District, Sigi Regency. The research was conducted for 3 months, from November 2015 to February 2016. The study site was located in Namo Village, Kulawi District, Sigi Regency, Central Sulawesi Province. This study used a completely randomized design (CRD) with 4 treatments, namely: (a) Class diameter I = 60-70 cm, (b) Class diameter II = 70-80 cm, (c) Class diameter III = 80-90 cm, (d) IV diameter class = 90-100 cm with 5 replications. The research data was analyzed by variance. The results showed that the value of pine sap production (Pinus merkusii Jung et de Vriese) in IV diameter class (90-100 cm) was 37.882 gr / tree / 7 days, diameter III class (80-90 cm) was 35.602 gr / tree / 7 days, diameter II class (70-80 cm) is 31,934 gr / tree / 7 days and class diameter I (60-70 cm) is 28.84 gr / tree / 7 days. From these results, the treatment of IV diameter classes is significantly different from the treatment of diameter classes III, II, and I.Keywords: Production of Pine Gum, Diameter Class, Koakan

Abstract

Mahogany has rapid growth and produces hard mahogany which is automatic for furniture. An important factor that determines the success of mahogany is the availability of quality seeds. For this reason, the things that need to be known are the availability of sufficient nutrients and air for seedling growth. In meeting the needs of seedlings, NPK compound fertilizers. The purpose of this study was to determine the growth of mahogany seedlings at various doses of NPK compound fertilizer. The research method is a Completely Randomized Design (CRD) consisting of four treatments, namely P0 = Land (control), P1 = Land + NPK fertilizer with a dose (5 g), P2 = Soil + NPK fertilizer at a dose (10 g) and P3 = Land + NPK fertilizer with a dose (15 g). Each treatment was repeated five times requiring 20 seedlings of 20 experimental samples, each polybag containing one mahogany seedling. The data used are the results of the analysis using in-depth or very realistic analysis and analysis using the Honest Real Difference Test (BNJ) at the level (5%). The results showed that the dose of NP fertilizer was very significant for all parameters, namely seedling height increase, stem diameter increase, number of leaves, seedling wet weight and seedling dry weight. Soil treatment + NPK fertilizer with a dose (15 g) (P3) gives the best influence on the growth of mahogany seedlings in almost all parameters that know, where the average seedling height increase, which is 2.40 mm, increase in stem diameter, ie 1.21 cm, increase in number of leaves, ie 3.03 strands, seedling wet weight, ie 2.75 g and seedling dry weight of 2.15 g.Keywords: NPK fertilizer, mahogany, Swietenia mahagoni (L) Jacq
