Abstract

The productivity of manglid (Magnolia champaca (L.) Baill. Ex Pierre) as the prominent plant commodity in West Java, can be improved by environmental manipulation such as spacing and fertilization. The objective of this research is to identify the effect of plant spacing and the use of goat urine as the leaves fertilizer on manglid planting until 19 month old. We used Randomized Block with Split Plot Design using three times replication. Main factor to be considered is the plant spacing with three different space :3 x 3 m (J1) ; 2 x 3 m (J2) and 2 x 2 m (J), while the secondary factor is three different doses of goat urine given : control (P1), 240 ml (P2), and 480 ml(P3. The results showed that the best treatment of planting manglid were treatment spacing of 2 x 2 m with goat urine fertilizer application as much as 240 ml per plant that produces high 191,5 cm and 3.83 cm of diameter up to the age of 19 months.

Abstract

The aims of this study was to identify the species and describe the morpohology of roosting tree used by sampiri colonies. The research was conducted form February to May 2014. Direct observation and recording morphology characteristic of the roosting tree were used as methodology. Data were analyzed descriptively and qualitatively and then displayed in the form of images and tables. There were six sampiri colonies using different roost trees. The roost trees were gehe (Pometia corriacea Radkl), binsar (Ficus variegata Blume), lawean (Sterculia sp.), dominated by gehe.

Abstract

The procurement of good quality seeds for the development of mindi (Melia azedarach L.) in the community forest is absolutely necessary. The purpose of this research is to investigate the diversity of the viability and seedling vigor of mindi from different populations with various treatments of dormancy breaking. The sample materials were mindi seeds that were collected from 6 locations (6 seed lots) or seed sources which were located in the community forest of West Java. There are 10 treatments of dormancy breaking that were applied in this study. The experiment design was Randomized Complete Design (RAL). The breaking dormancy was focused to the delignification of hard seed coat. Results showed that the most effective dormancy breaking for mindi seed was soaking in consentrated Sulfuric Acid (H2SO4) as long as 30 to 45 minutes. The first count for germination of mindi was on the 16 day and the final count was on the 31 day.The average value of germination percentage (DB) for all seed sources was 40 %, while the highest which is 60% was mindi from Sumedang seed source. The highest value of germination rate that is 6,543%/etmal was seed from Sumedangand seed from Gambung was the lowest (1,400 %/etmal).

Abstract

This Research aims to determine (1) History, actors and the causes of conflict in terms of the social aspect of economic, cultural and institutional happened in PFMU Model Poigar (2)Recommendations settlement to parse tenurial conflicts PFMU Model Poigar. Data analysis method used is a qualitative approach. The results showed that land claims by communities began of forest utilization activities to meet basic needs. Tenurial conflicts PFMU Model Poigar is a structural conflict. Some of the main actors should receive priority attention is the processing community land in the area and local employers. Some of the basic causes of conflict tenurial PFMU Model Poigar is a lack of understanding about the existence of related parties PFMU Model Poigar, the dualism of authority, lack of community empowerment, and law enforcement is still weak.Based on consideration of the history, the actors involved and the cause of the conflict, then some of the recommendation of this study is the institutional strengthening KPHP Poigar model, the development of that partnership, and law enforcement.

Abstract

Precise forest inventory to estimate standing stock is needed in forest management planning. Therefore, it is necessary to have proper and reliable tools in estimating merchantable timber volume. This research was intended to build an accurate model to estimate timber volume for merchantable species in logging concession of PT Wapoga Mutiara Timber, Sarmi Regency. Regression equation between diameter and length did not have a significant correlation (coefficient of determination, R2 = 6.7 %). The best equation to estimate table tree volume based on validation test in logging concession of PT Wapoga Mutiara Timber was Log V = - 3.34 + 2.16 log d.

Abstract

There are 14805.14 ha of North Sulawesi coastal ecosystems that has been damaged. Baringtonia asiatica Kurz (Keben) is one type of coastal plants that can be used to protect coastal areas . Unfortunately, the propagation technique of Keben was not widely studied. This study aims to determine the characters of seedlings produced from the stumps of seed germination. The research used Complete Random Design with nine treatments, consisting of combination betwen three levels of root length (0 cm, 5 cm and 10 cm), and three levels of the stems length (5 cm, 15 cm and 30 cm). Parameters for analysis include percent of success, growth and quality index. The results show that root length and stem length factors significantly affect the height and robustness value. Treatment of root length of 10 cm and 5 cm rods allegedly produces the most excellent quality with the survival rates 93%, height 10.3 cm, diameter 1.08 cm, robustness value 2.03 and index of seed quality 1.35. Based on regulation of land rehabilitation, the height of 10 weeks stump have not qualified yet.
