Eucalyptus sp is a type of exotic plant that is cultivated in Riau Fiber. Particularly in terms of soil, this Eucalyptus species was developed in soil management unit B and soil management unit C. Differences in variations in plant growth in the two land management units are not known with certainty because there is no accurate information. This research was conducted at the East Teso Estate which is one of the forest management units of Riau Fiber which included measuring tree height with variations in age of 6 months, 12 months and 18 months, as well as tree diameter and calculating the percentage of single trees with variations in age of 12 months and 18 months. in the land management unit B and soil management unit C which were tested using the t-test at a test level of 5%. The results showed that height growth had a significantly different effect on the two soil management units, namely 4.39 m in soil management unit B and 3.62 m in soil management unit C at 12 months of age and 6.43 m in soil management unit B and 5.87 m in soil management unit C at 18 months old. As for plant height at 6 months, diameter and percent of single trees aged 12 months and 18 months, the results were not significantly different in soil management unit B and soil management unit C.

The development of modern industries has demanded ever-increasing usage requirements for wood products. The use of wood will be more effective and efficient if the properties of wood are known beforehand. This study aims to determine the anatomical diversity of sengon wood and its possible use as a raw material for furniture. This study used a randomized block design with Tukey's follow-up test. The factor used consisted of the radial direction of wood (wood near the skin and wood near the heart). Parameters observed were the proportion of fiber cells (%), the proportion of vessel cells (%), the proportion of parenchyma cells (%), and the proportion of radius cells (%). The results showed that the wood near the skin and near the heart of sengon had variations in the proportion of fiber cells, the proportion of vessel cells, the proportion of parenchyma cells and the proportion of radius cells. The average value of the anatomical diversity of sengon wood in the radial direction is the proportion of fiber cells 49.02 - 50.24 %, the proportion of vessel cells 23.22 - 24.23 %, the proportion of parenchyma cells 13.47 - 14.57 %, the proportion of finger cells finger 11.53 - 13.39 % and . Sengon wood can be used as furniture material for light buildings or for artificial boards because it has a high proportion of fibers.

Community forests in Gunungkidul have developed for a long time and are managed in a traditional way, known as pekarangan, moor and wono. Most of the community forest planting patterns found in Semoyo Village are agroforestry patterns, where trees are planted with a mix of various tree species and one type is dominated, for example teak or mahogany. This study aims to determine the differences in the shape of the diameter distribution of mahogany and teak in dry fields and yards which are dominated by one tree species. The method used is quantitative analysis to produce diameter distribution and draw a curve to describe the stand structure. The results showed that for the type of mahogany in the yard and moor in all class diameters, the number of trees was higher than teak. The diameter distribution of mahogany and teak both in the yard and dry land both showed a shape that resembled an inverted J and was successfully modeled using the exponential model.

One of the wood industry activities in the forestry sector is the Eucalyptus sp industry at PT.Riau Mainstay Pulp and Paper Riau Province. The wood production process is used for pulpand has many factors in its productivity. One of them is in the planting process with weedcontrol problems, which use the herbicide with the active ingredient glyphosate. The use of the herbicide with the active ingredient glyphosate is not effective against all types of weeds. Therefore, it is necessary to know the right combination of weed control methods to control weeds for the expected results. Research is located in PT. RAPP, Kuantan Singingi Regency, Riau Province. The research design used was a completely randomized design with a factorial pattern that used 2 treatment factors in the form of Weeding Round consisting of Weeding Round 5 Over Due (late weeding) and Weeding Round 5 On Time (on time) and weed control methods consisting of chemical methods, the tripe combination method with chemical and thecombination lever method with chemical. The parameters observed were the type and amount of weed vegetation, the development of weed death, the percentage of weed death and the PQA value of weeding. Data were analyzed by analysis of variance. The results that showed a significant effect were further tested using the LSD (Least Significant Difference) test. The results showed that there were 6 types of weeds found in the research area, namely Senduduk Bulu (Clidemia hirta), Senduduk (Melastoma malabathricum), Acacia mangium saplings (Acacia mangium), Lemidi Paku (Stenochlaena palustris), Grass (Poaceae) and Liana. The most dominant type of weed was Clidemia hirta with an Important Value Index of 127.72% and the weed with the smallest effect was liana with an Important Value Index of 0.88%. Based on the results of the analysis of the development of weed mortality, the percentage of weed mortality and the PQA value of weeding, the combination of jackhammer and chemical method is the most appropriate control method applied because it has an average PQA value of 100%.In the chemical method there are fern weeds that are difficult to die and in the combination tripe and chemical method there are fern weeds that grow new leaves on the 16th day of observation.Keywords: PQA Weeding; Weeds; Weed Control Methods

Pine resin is a non-timber forest product, which has the potential to be developed in Indonesia. One of the pine resin products is gondorukem which has a very wide market. The purpose of this study was to determine the best tapping method, in order to obtain optimal production of pine resin tapping in three age classes of pine trees, namely age classes III, IV and V. The results showed that the average yield of pine resin tapping with the quare method was 18 ,88 gr and drill method 17,77 gr. Meanwhile, the highest average production of sap in age class III was 26.11 g and the lowest was in age class V of 10.21 g. The results also showed that along with the increase in the age class of the plant, the production of tapping sap also decreased significantly, both for tapping pine sap using the drill method, and tapping pine sap using the quare method. The results also showed that as the age class of the plant increased, the use of the quare method gave a higher average yield of 18.88 gr than the drill method of 17.77 gr.

The results also showed that as the age class of the plant increased, the use of the quare method gave a higher average yield of 18.88 gr than the drill method of 17.77 gr.\u0000Keywords : Age class; tapping method; pine resin production","PeriodicalId":426857,"journal":{"name":"Jurnal Wana Tropika","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133306234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Gmelina (Gmelina arborea Roxb.) seed is a type of seed that have physical dormancy. This is because water and gases prevent by the hard seed coat during the germination process. Therefore, to break dormancy, preliminary treatment in the form of scarification is required, including using sulfuric acid (H2SO4) solution. This study aims to determine the treatment of soaking in a 96% concentration of H2SO4 solution that produces the best germination ability. The study used a completely randomized design method (CRD) with 5 soaked time treatments, namely control (0 minutes), 5 minutes, 10 minutes, 15 minutes, 20 minutes and each treatment was repeated 3 times with 50 seeds for each replication. The results showed that soaked the seeds in the 96% concentration of H2SO4 solution had a significant effect on on initial time of germination, last time of germination, 80% limit time for germination, percentage of germination and vigor index. Soaking time for 10 minutes is the best treatment for scarification of gmelina seeds. Keywords: physical dormancy; pre-treatment; scarification; soaking time
