Abstract

Shorea spp. is one of the most widely used wood types by the community. In addition to the economic value of wood, the Shorea group also has a non-timber economic value. Plants need sunlight for growth and development. The intensity of light is one of the most important factors in the process of photosynthesis to produce energy as fuel for plant growth. Shade can be interpreted as a shelter or something that can protect plants from excessive direct sunlight. Shorea leprosula Miq. is a type of semi-tolerant plant that needs shade. In this study, we will try to apply the science of Agroforestry, which is a combination of plantation and forestry plants, by planting red meranti seedlings under the auspices of oil palm stands by paying attention to the direction of the source of sunlight. The method used in this study is a randomized block design (RCBD), which consists of 5 treatments and 4 groups. This study uses 5 treatments with different light source directions, namely A0 (Shade without Shade or control), A1 (Position of seedlings in the East), A2 (Position of seedlings in the North), A3 (Position of seedlings in the South) and A4 (Position of seedlings in the West). The direction of the light source  the position of seedlings in the south under the auspices of oil palm stands turn out to be better for plant growth because it gets a long period of light exposure from morning to evening. Keywords : source direction,sunlight,growth, Shorea leprosula Miq., shade, oil palm stand.

Abstract

Revegetation is an effort to restore peatland after it is damaged. Dyera lowii is a type of forestry plant has a high potential to be developed because this tree is suitable for planting on peatland. To get good growth of Dyera lowii nutrients are needed, one of which is by providing compost. The solid waste of the sago industry that has accumulated will experience decomposition so that it becomes compost. The purpose of this research is to determine effect and the best dosage of sago dreg compost of Metroxylon sagu on the growth of Dyera lowii on peat media. The study used a Completely Randomized Design method consisting of 4 treatments and 4 replications so that 16 units of the experiment would be obtained. The treatments are : S1 = without Metroxylon sagu compost, S2 = 20% Metroxylon sagu compost + 80% peat soil, S3 = 50% Metroxylon sagu compost + 50% peat soil, S4 = 80% Metroxylon sagu compost + 20% peat soil. Data further analyzed using variance, with SPSS software version 20.0. If the results of variance have a significant effect, then further analysis is done using the DNMRT test at the 5% level. Application of sago dreg compost of Metroxylon sagu influences the growth of swamp Dyera lowii and the best dosage of the four treatments were S1 treatment (20% + 80% Metroxylon sagu compost) with 95% survival rate, 0.83 cm height increase, and plant dry weight 0.60 gr. Keywords: Metroxylon sagu compost, Dyera lowii  Hook.f, peat media

Abstract

Bagasse is a waste which is usually dumped in open dumping without any further processing, so it will cause an enviromental disturbance. It is important to apply a technology to overcome the waste by using the recycle of solid waste into a use value of compost product. Top soil has been hard to find, because it is used continously in long time or has been eroded which cause the decreasing of avalaiblity. Alternative to avoid the decreasing of soil media quality, so the use of compost is predicted to increase the supply of soil nutrient. The purpose of this research is to determine the effect  of composting formulated bagasse for Acacia crassicarpa seedlings in top soil medium and to determine the best dose for seedling growth Acacia crassicarpa. This research uses a completely randomize design method which consist of 5 treatments, 4 replications, and 5 units of the plant as a research unit. P0 = without composting  formulated bagasse ; P1 = 25 g/polybag ; P2= 50 g/polybag ; P3 = 75 g/polybag ; p4 = 100 g/polybag. The result of this research indicates that  the composting formulated bagasse with 100 g/polybag dose is the best treatment in the parameter observations, the high increasing (36.45 cm), the diameter increasing (0.37 mm), the seedling dry weight (11.93 g), and the ratio of the root crown (6.40) for seedling Acacia crassicarpa in top soil medium.
