Abstract

Aren (Arenga pinnata Merr) is a type of palm plant that produces fruit, sap and starch or flour in the stems. Peat from its natural formation process has a low fertility rate because it contains high organic acids. Rice husk ash is the result of burning rice husk which can improve soil properties, so that it can support more optimal plant growth and development. The purpose of this research was to determine the effect of the application and the best composition of rice husk ash on the growth of palm seedlings on peat medium. This study used a non-factorial completely randomized design (CRD), which consisted of one factor, namely the dose of rice husk ash with 5 treatment levels and 4 replications in order to obtain 20 experimental units. The treatment of rice husk ash (T) consists of 5 levels with the following dosages: T0 = without application of rice husk ash (control) 100% peat, T1 = application of rice husk ash 10% polybag + 90% peat, T2 = application of rice husk ash 20 % polybag + 80% peat, T3 = application of rice husk ash 30% polybag + 70% peat, T4 = application of rice husk ash 40% polybag + 60% peat. The application of rice husk ash affects the dry weight of palm (Arenga pinnata Merr) on peat medium. The best application of rice husk ash at a dose of 40% rice husk ash plus 60% peat can increase the growth of increase in diameter 0.29 mm, plant dry weight of 1.92 g, crown ratio root 2.25. Keywords : Arenga pinnata, rice busk, growth.

Abstract

The expansion of the use of peat was not wise, causing the rate of peat destruction to be very fast. Peatlands in Riau have a large enough potential to be planted with various types of forest plants. Efforts are needed to achieve optimal plant growth on peat soils. Trichoderma sp. as Tricho-Compost, it was hoped that it can spur growth and improve the quality of Arenga pinnata plants. The purpose of this study was to determine the effect of Tricho-Compost application on the growth of Arrenga pinnata seedlings on peat media and to determine the best dosage of Tricho-Compost on Arenga pinnata seedling growth on peat media. The research was conducted using a completely randomized design (CRD) consisting of 4 treatments with 5 replications in order to obtain 20 experimental units.The compost of compost at several levels of concentration, namely: D0 = Without Tricho-Compost (Control) application, D1 = 25% Tricho application -Compost + 75% peat soil, D2 = Application 50% Tricho-Compost + 50% peat soil, D3 = Application 75% Tricho-Compost + 25% peat soil. The data obtained from the research results were statistically analyzed using Analysis of Variance (ANOVA) and further analyzed using Duncan's New Multiple Range Test (DNMRT) at the 5% level. The application of Tricho-Compost fertilizer has an effect on the growth of Arrenga pinnata seedlings. The application dose of Tricho-compost D2 fertilizer (application of 50% tricho-compost + 50% peat) shows the best treatment to increase the growth of Arenga pinnata seedlings in peat medium showed of a percent live yield as 96%, height increase as 17.25 cm and a top-root ratio as 3.71.Keywords : Arenga pinnata, Tricho-Kompos, growth

Abstract

Cratoxylon arborescens is a local tree of peat swamp forest that has the potential to be a candidate for planting in the initial phase of peat restoration. Quality seeds will be produced from well-managed nurseries. One aspect of nursery management is the provision of appropriate fertilizers and the right dosage. Giving this fertilizer can be done using tofu liquid waste. The purpose of this study was to determine the effect of tofu liquid waste on the growth of Cratoxylon arborescens seedlings and determine the best composition of tofu liquid waste to spur the growth of Cratoxylon arborescens seedlings. This research was conducted with a completely randomized design method (CRD), which consisted of 5 (five) treatments. Each treatment was repeated three times, so that 15 unit experiments could be obtained. Each experimental unit consists of five plants so that the total plant is 75 units. Concentration of tofu liquid waste for Cratoxylon arborescens seedlings is without giving (control), 20%, 40%, 60%, and 80%. The results showed that the application of tofu liquid waste affected the growth of Cratoxylon arborescens seedlings. The best composition of giving tofu liquid waste is giving tofu liquid waste as much as 20% (Treatment P1) with a yield of 100% life, height growth of 16.84 cm, seed diameter of 3.60 mm, plant dry weight of 4.18 gr and the top-root ratio of 2.72.Keywords : Cratoxylon arborescens, tofu liquid waste, Growth

Abstract

Trigona spp. is include into stingless bee honey. Trigona spp. has another names, such as, galo-galo (Sumatera), klanceng, lenceng (Jawa), andteuweul (Sunda). The population of Trigona spp. in many areas in indonesia. Trigona spp. produce are honey, pollen, royal jelly, propolis and beeswax. People do not know much yet about the benefit and how to cultivation of Trigona spp. type, material and size of bee’s nest. The purpose of this research is to know successfull affectiveness movement of Trigona spp. in type, material and size of artificial nest. This research used two method, survey and experiment. The first survey got 19 bee’s nest of Trigona spp. in 7 trees. In the next experiment, the resercher tried to test 6 artificial nests (2 bee’s nest made by half of a coconut shell, 2 bee’s nest made by bamboo and 2 bee’s nest made by wooden box) and the different size of box. The experiment of 6 artificial nests was a theory of eduction/attachment. The artificial nest affixed to red chelate tree (Syzygium sp.), kempas (Koompassia malaccensis), jackfruit (Artocarpus heterophyllus) and red chelate tree was moudly/dead. The result of this research show that type of Trigona spp. that lifeatThe Prohibition Forest of Indigenous Village of Rumbio Kampar Regency. There are three kinds : Trigona collina, Trigona incica andTrigona terminata. The preferred and ideal artificial nest of Trigona spp. was wooden box 3 segment in Ttot = 65 cm, basic segment T1 =30 cm, middle segment T2 =25 cm andtop segment T3 = 10 cm.Key words:Trigona spp., The Prohibition Indigenous Forest, artificial nests

Abstract

One of the non-timber forest products that have the potential to be developed of honey from  Trigona  spp. which have cultivated in the area of forest by community. Trigona spp. is one of bees without sting. Many  Trigona spp. defend themselves with  biting their enemy. This bees will biting their enemy or burn their enemy  with dissolved chemical alkali. The lack of information and understanding about potential of Trigona spp. Cultivation and utlization arround forbidden forest in Rumbio customary also the unmaximal benefiting by community arround forbidden area. The purpose of this research to understand community interest and perception toward Trigona spp. cultivation arround forbidden forest in rumbio customary. This research has be done in the forbidden forest area, Siboghia, Rumbio Village, Kampar District, Riau Province. The sample thad been  used is purposive sampling.  Respondents that has been selected for this reasearch are 30 peoples from forbidden community. Respondents living passed arround forbidden forest, and had a farm in area, as the main data source of this research. Based on this research, it can be seen that community interest and perception toward Trigona spp. cultivation are good. The respondents not only know about the type and physiology of Trigona spp., but also know the habitats and products of Trigona spp. The knowledge of respondent still not enough. But the interest of respondents to cultivating Trigona spp. Is sufficient. Keywords : public perception, interest, Trigonaspp.

Abstract

Alstonia scholaris is a high economic value, fast-growing species and spread widely. Alstonia scholaris used to overcome the problem of damage in mining fields. Besides that Alstonia scholaris is tolerant in various kinds of soil. Alstonia scholaris seeds was difficult to obtain is one of the constraints for large-scale planting. The propagation vegetatively or using the hormone of auxin help. The observations is to observe growth of Alstonia scholaris stem cutting increase speed growth of shoots, numbers of shoots, length growth of shoots and number of leaves. Used level of concentration were non-concentration (K0), 50 ppm (K1), 100 ppm (K2) and 150 ppm (K3). The results of study shows the best concentration at a concentration of 150 ppm (K3) with level of shoots growth is 0,42 day, average of shoots length is 0,36 cm and average number of Alstonia scholaris leaves is 4,30 pieces.Keywords: Alstonia scholaris, cutting, concentration, auxin hormone, growth
