Abstract

Protection of safety and occupational health is still far from expected because there are still many accidents and potential work hazard that many endanger the workers. Yet until now they do not have good reference on standardization of producttion process and product standardization, one of them is safety and occupational health standard (K3). The absence of such standardizationcause business owner pay less attention to environmental conditions and business facilities. Problem arise are workers tend to work without sufficient knowledge and ignore the use of personal protective equipment (PPE). These things cause workers to be susceptible on disruptions, accidents and illnesses arising from working condition. The aim of this study was to identify the hazard in the implementation of safety and health in the sawmill Berkat Shalawat Tembilahan district Indragiri Hilir regency.This research used descriptive analysis with observation method and interview with took sample of all workers in Berkat Shalawat industry. The result ofidentification indicated that the dominant danger source of accidents at the stages of loading and unloading, wood clearance and loading to the mean of transportation, those are wounds from wood fiber, pincers, crushed wood etc. In other hand, workers also experiance musculoskeletal symptoms, coughing, fatigue and decreased vision and hearing fuction that are shown in physical, chemical, biological and ergonomic factors. Keyword: Safety and Occupational Health, Hazard Source, Personal Protective Equipment (PPE).

Abstract

Agroforestry is one of the land management systems that can be offered to overcome the problem of forest land convertion. The success of agroforestry  plant growth is influenced by aspects of which are protection from pests. Pest attacks can decrease the potential of standing, both quality and quantity. This study aims to determine the intensity of pest attacks on agroforestry of teak stand (Tectona grandis). Research activities carried out on the Rajawali Sakti street Simpang Baru village Tampan districts. The method used in this research is random sampling. The area covered is 3 Ha with sample intensity of 10% that is 0,3 Ha. An observation plot was made of 10 m x 10 m of 30 plots. The research indicate that the intensity of pest attack on stand of teak is amount to 22,13% which is included in the category of minor damage. Pests that attack teak plants such as caterpillar teak (Hibea puera), white lice (Paracoccus marginatus), white butterfly (Bemisia tabaci), termites (Neotermes tectonae) dan black ants (Polyrhachis Spp). Keywords : Agroforestry, Teak stands (Tectona grandis), Pest, Intensity of attack (IS).

Abstract

This research aimed to determine the effect of the role water immersion of Piper betle leaf. Protect Paraserianthes falcataria of seed quality and know the best dosage Piper betle leaf soaking in Paraserianthes falcataria maintain quality seed. The research method used in completely randomized design (CRD) with 4 treatments and 4 replications. The treatment consisted of: S0=Paraserianthes falcataria soaking seeds without Piper betle leaves in 1 liter of water; S1=Paraserianthes falcataria soaking seeds with 100 g of Piper betle leaves in 1 liter of water; S2=Paraserianthes falcataria soaking seeds with 200 g of Piper betle leaves in 1 liter of water; S3=Paraserianthes falcataria soaking seeds with 300 g of Piper betle leaves in 1 liter of water. Research has shown that the Paraserianthes falcataria seeds soaking with water immersion Piper betle leaf able to maintain seed quality. Soaking seeds Paraserianthes falcataria with 300 g Piper betle leaves in 1 liter of water is the best treatment against the percentage of seed germination (81%), the rate of seed germination (3.42 days), increasing the height of drill (4.07 cm) and the time of seed germination (81% in 9 days).

Abstract

Eucalyptus sp. is fast growing species reproduced in industrial vegetation forest (IVF) as the raw material for the production of pulp and paper. In order to support the availability of raw material, an effort to increase the stands productivity is carried. In this case, one of the methods is by doing plant breeding with both vegetative and generative ways. The purpose of this research is to analyze the difference in the growth level and the quality of the fiber of the Eucalyptus sp. based on the generative and vegetative method in reproduction.This research using  Randomized Complete Block Design (RCBD) consist of two (2) treatmens and four (4) replications and ten (10) units trial. The result of the research shows that vegetative growth is better than the generative growth with the average of vegetative growth for its length is 0.55 m and the average of growth for its diameter is 0.53 cm while the average of the generative growth for its length is 0.15 m and average of the growth for its diameter is 0.13 cm. The quality of the fiber of the Eucalyptus sp. with vegetative method is longer than the generative method. Keywords: Eucalyptus sp., vegetative, generative, length of fibre

Abstract

Aquilaria malaccensis Lamk. in trade name of the wood product (incense) results by few of tree species that resulting agarwood. In few of international tend, this product known as agarwood, aloeswood or oudh. Cultivation of Aquilaria malaccensis Lamk. is the most important thing to did for conserve this type. Agarwood is Not Wood of Forest Product (NWFP) that has high economic value so plants of agarwood should be expanded, but in Aquilaria malaccensis Lamk.  plants cultivation not easy to did, therefore for the growing must gived treatment by giving PGR, so that plant grows be better. Therefore need to know better types of PGR for growth of Aquilaria malaccensis Lamk.  at  seedling stage by different PGR giving. The aims of research is knowing Aquilaria malaccensis Lamk.  seedling by various types of plant growth regulator. This research used Completely Randomize Design (CRD) consisting of 4 treatments with 3 repetitions, for each respective unit consist of 10 seedling, so total of all experiment unit is 120. Observation data analyzed by variance analyze if showed real effect or very real effect to be continued by the Smallest Real Test (SRL) 5%. Plant Growth Regulator (PGR) giving Rootone F with 750 ppm concentration results better tend to improve quality of Aquilaria malaccensis Lamk.  seedling in terms of survival percent 76,66%, high seedling added 3,06 cm, diameter seedling added 0,28 mm.

Abstract

Samanea saman tree species that have great ability to absorb carbon dioxide from the air. Samanea samangrowthnot be separated from the problem of pests and diseases. Pests that attack Samanea samanand often result in losses that Plusia sp. Indonesia has a very diverse flora, contains quite a lot of kinds of plants which are sources of pesticides that can be used for pest control. The use ofCerbera manghasleaf extractas a botanical pesticide for controlling Plusia sp. of the Samanea saman is an alternative that can be used as an environmentally friendly pesticide.This research aimed to know the effect ofCerbera manghas leaf extract in controlling Plusia sp. and determine the exact concentration of the level of Plusia sp. mortality of the Samanea saman.This research uses a Completely Randomized Design Method, which consists of 5 treatments and 4 replicates with concentration levels of botanical pesticide. B0 = concentration Cerbera manghas leaf extract 0 g/l of water; B1 = 5 g/l of water; B2 = 10 g/l of water; B3 = 15 g/l of wate;B4 = 20 g/l of water. The results showed that the application of Cerbera manghas leaf extract at the concentration of 20 g/l of water is the best concentration in controlling Plusia sp. with results initial time of death fastest is 3.00 hours, the fastest time of turning off 50% (LT50) is 11.25 hours (11 hours 15 minutes) and total mortality amounted to 92.50%. Keywords:Samanea saman, Plusiasp., Cerbera manghas leaf, botanical pesticide
