Abstract

Riparian ecosystems have a protective function of watersheds from pollution. One important component in riparian ecosystem is the presence of phytoremediation plants, which can degrade contamination content. This research is intended to identify the presence of undergrowth that functions as phytoremediation in Bojongsoang District which is one of the areas around the heavily polluted Citarum watershed zone[1]. The method used in this research is vegetation analysis using the quadrant method with 1x1 m2 plot size. Determination of sampling points used purposive sampling method. The results of the study found that the undergrowth as a potential phytoremediation included rumput teki (Cyperus rotundus), Beluntas (Pluchea indica), Alang-alang (Imperata cylindrica), Jejarongan (Chloris barbata), rumput gajah (Cyperus rotundus), and bayam duri (Amaranthus spinosus). Rumput teki (Cyperus rotundus) is phyto-extractions in mercury-contaminated soils and accumulators of Sn, Zn, As, Cu, and Pb. Alang-alang (Imperata cylindrical) is a cyanide phytoremediator which is able to extract Zn from contaminated soil, and absorb Pb from contaminated soil. Beluntas is able to accumulate Cu, Fe, Al, Pb and Zn in their roots, leaves and stems, and the leaves that can absorb Cr. Rumput gajah (Cyperus rotundus) are a Cd accumulator. Bayam duri (Amaranthus spinosus) hyperaccumulator against mercury. Studies on the presence of phytoremediation plants can provide preliminary information on the condition of riparian ecosystems in the Citarum watershed.

Abstract

Good quality cajuput seedlings procured from generative propagation are essential, since the mature trees will be functioning as oil production trees, stock (parent) plant for stem cuttings, and major players on land conservations.In addition to superior genetic factors, the so-called Plant Growth Promoting Rhizobacteria (PGPR) treatment with the optimum concentration would help in enhancing the quality of generative seedlings. Therefore, systematic experiment is needed to determine the effective concentration of PGPR required for preparing high quality cajuput seedlings. This study used Completely Randomized Design (CRD) experiment with randomly assigned concentration of PGPR on cajuput juvenile as the primary factor. The height growth and root length growth of the juvinile for given period of time were measured to evaluate the effect of PGPR treatment. There were monotonically improvement on juvinile’s height and root length growth after PGPR treatment, showing a positive correlation between the height and root length. During the experiment, the highest PGPR concentration of 90mL/L was discovered to be the most effective. Nevertheless, they still had not reached the saturation point yet, therefore, more study is needed to determine the most optimum PGPR concentration to produce the exemplary cajuput seedlings.

Abstract

The problem faced by the wood processing industry in Indonesia today is the shortage of wood raw materials. This occurs because the speed at which timber is used is not balance with the speed at which new stands are build. Meanwhile, the need for wood for furniture, building materials and other needs continues to increase in line with population growth. Therefore, it is necessary to find alternative raw materials for the wood processing industry. Bamboo is one material that can be use for this purpose. Bamboo is a long fiber and has advantages in terms of the harvest period, namely within 3-4 years it can be harvested, shorter than 8-20 years for fast-growing timber species. In this research, a combination of fiber and laminate boards with epoxy adhesive. The material used is the type of betung bamboo (Dendrocalamus asper) and then tested on the combination of fiber and laminated bamboo boards there are 3 tests, namely fracture strength, absorption capacity and density.  The results of this research indicate that from the treatment of 255g adhesive and 127.5g of fiber has a higher average compared to 127.5g of adhesive and 255g of fiber. From the test results, the combination of fiberboards and laminate boards as HDF (Hard Dencity Fiberboard) classified which can be used for materials for making adhesive walls, ceilings, pinyi and containers. However, in contrast to the 127.5g adhesive and 255g fiber treatment included in the MDF (Medium Dencity fiberboard) classification, furniture such as household appliances, molding, window frames, door skins and car dashboards are used.

Abstract

ABSTRACTThis study aims to determine whether there is an effect of cropping plants on the growth of pine (pinus merkusii), eucalyptus (eucaliptus alba), puspa (schima wallichii) and avocado species (parsea americana) on RHL activities in RPH Tarogong, BKPH Leles, KPH Garut, West Java and Banten regional divisions. This study was conduct in three series. First, determining the location to be measure second, determination of the measuring plot. Third, making plant measuring by size 40x25m with an area 0,1ha by using systematic sampling with random start metode. Primary data retrieval, namely from the results of the making of the measuring plots according to the plan, then recorded in the taly sheet and then processed according to the parameters determined in the study. Data analysis was conduct to determine the role of each cropping pattern on diameter. The height and robustness of the plants were analyze using the independent sample t-test of the unpaired independent variables. Thus, we can formulate a general definition that the independent sample t is a statistical analysis that aims to compare two unpaired samples. Based on the results of study and discussion, it can be concluded that the growth of eucalyptus (Eucaliptus Alba) and Puspa plant spesies (Schima Wallichii) is better in the agroforestry pattern than in the non-agroforestry pattern. The growth of pine (Pinus Merkusii) and avocado plants (Parsea Americana) is not affect by cropping patterns, so these types can be plant in both agroforestry and non-agroforestry cropping patterns.

Abstract

This research was carried out in RPH Ujung Berung, BKPH Manglayang Barat KPH Bandung Utara, and Divisi Regional Jawa Barat & Banten. The time of the research was conducted from September to November 2018. The purpose of this study was to determine the effect the effect of age classes, diameter difference and interaction between age and diameter. Based on the results of the research it can be concluded that the productivity of pine resin is affected by the age class. It showed by data increased in age class followed by increased productivity of resin. Age Class IV is 13.26 grams, Age Class V is 30.74 grams and Age Class VI is 61.17 grams. There is a tendency for latex production to increase by the time the tree grow older to a certain age. Diameter affect the productivity of resin, the greater the growth of tree diameter, the more abundant the resin can be and the production of pine resin will increase. This is shown by data increased in diameter followed by increasing resin productivity, in diameters of 20-23 productivity of resin is 29.7 grams, diameter 24-27 productivity of resin is 36.44 grams and diameter 28-31 productivity of resin is 38.95 grams. Age classes difference affect the amount of resin production, the older the tree ages, the larger diameter will be, and finally affect to resin productivity, up to a certain age limit.

Abstract

Pine sap exploitation is growing because demand for pine sap in Indonesia and the world is increasing. Pine sap productivity is influenced by several factors including tapping, tree species, diameter, and age of stands. In the tapping method, one of them is the renewal time of tapping with the quarre system which is supposed to save the tapping area and get the maximum sap. This paper studies the effect of the renewal of the pine tree tapping at different ages on the productivity of the sap. The proposed method is a survey with a purposive sample determination with 3 different treatments, namely treatment A of the 3-day quarre renewal, treatment B of the 5-day quarre renewal, and treatment of the renewal of the 7-day quarre by administering stimulants. Performed at different age classes IV, VI, and VIII. Field observational data is then processed using a factorial Completely Randomized Plan analysis with two factors. The results showed that the renewal of quarre had a significant effect on the average productivity of pine tree sap at 95% confidence intervals (α = 0.05). The highest average productivity on treatment B renewal of 5 days quarre was 12.17 grams /quarre/day at age classes VI and the lowest average productivity was at treatment C of renewal of 7 days with 4.61 grams /quarre/day at age classes IV.

Abstract

In the recent years, there is a significant increase on economic value of coffee as trade commodity. On that note, the most frequently used cultivation practices for coffee in Indonesia is coffee agroforestry system in private forest. However, there are still some constraints in the system development due to the traditional farmer limited knowledge of coffee cultivation practices. In this study we conducted preliminary observations on the coffee cultivation practices used by the traditional farmers to determine the steps needed to improve the coffee quality and sustainability. We study the effect of plant-spacing and shading on the growth of juvenile plant of coffee (Coffea arabica Lin.) from Sigarar utang variety. The observation was carried out in private forest of Cimarias village Sumedang district for 1 (one) month. We used the combination of 2,5m x 2,5m and 3m x 3m for plant-spacing with kayu afrika (Meisopsis eminii Engl.) as shade and without shade. This experiment used Completely Randomized Design experiment with 10 replication for each treatment, with juvenile height (cm), stem diameter (mm), and the quantity of productive primary branches as data. Then data were analyzed using Anova, Duncan’s Multiple Range Test (DMRT) 0,05, and Pearson Correlation. From the result, the best growth of juvenile plant of coffee tree was showed on 3m x 3m spacing with shade. However, the growth shown has not reached the potential of the coffee from Sigarar utang variety as supposed to in accordance with the environmental condition of the crop. This analysis also supports the prediction of low-productivity because there is positive correlation between juvenile height and the quantity of primary branches, and between stem diameter and the quantity of primary branches.
