Inventarisasi Hama Persemaian Di Hutan Tanaman Rakyat Desa Ngambur Kecamatan Bengkunat Belimbing Kabupaten Lampung Barat
Get PDFForest pest inventory is research activity to gather and arrange the data of pests existing in seedling periode. Pest inventory activites are used to determine pest types, the number and crop damage order to apply appropriate control. This research was aimed to identity the pest types and its attack levels at community plantation forest nursery. This research was conducted at Community Plantation Forest in Ngambur Village of Bengkunat subdistrict, West Lampung on April to May 2012. The collected data was identified taxonomically. The data was included of pest types, pest density, attack levels, and demages. All samples were collected using systematic method in diagonal pattern. The results was obtained 9 types in kadam nurseries, white albizia, and umbrella tree, which caterpillars (Daphnis hypothous), locust (Locusta migratoria),moths (Hyblaea puera), bag worm (Pteroma plagiophelps), bug (Cosmoleptrus sumatranus), mealy bug (Planococcus citri), leaf caterpillar (Doleschallia polibete), yellow butterfly (Eurema spp.), snail (Achatina fulica) and 1 type of insect predators that weaver ants (Oecophylla smaragdina). Insect population was high enough but not damage the plant nursery while the most dangerous insect pest was a bag worm (Pteroma plagiophelps) and moth (Hyblaea puera). Bag worm larvae cause severe damage, the loss on the leaves. The extent of damage by insect pests classified in the category of still mild attacks. Pest control can be done mechanically or chemically
Ukuran Benih Dan Skarifikasi Dengan Air Panas Terhadap Perkecambahan Benih Pohon Kuku (Pericopsis Mooniana)
Get PDFNedun tree (Pericopsis mooniana) is one of commercial trees. The propagation of nedun tree generatively has an obstacle due to it’s dormant character and the variety of seeds weight and the both factors are suspected influence the germanitaion. This research aimed to determine effect of seed weight for nedun seed germination and the best of seeds weight for nedun seed germination; the effect of soaking in hot water at beginning temperature 80˚C by different soaking period on germination, and the best effect of soaking in hot water at beginning temperature of 80˚C by different soaking period on germination. This research was compiled in a randomized complete block design, with 5 treatments and 3 groups. Seeds were catagorized in to three group of weight which were heavy, medium, and light. The treatments consisted of without scarification (as a control), soaking in hot water at beginning temperature of 80ºC during 12 hours, 24 hours, 36 hours, and 48 hours. Every experiment unit consisted of 100 seed. The observed variables were consisted of germination percentage, mean daily germination, germination value, and the ability to germinate. Data analysis methods were used variance homogenity, variance analysis and least of difference test at 5% significant level. Based on the analysis of variance showed that seeds weight significantly affected the mean daily germination, but had no effect on germination percentage, germination value, and the ability to germinate. Seeds weight had a mean daily germination 15.088 days to germinate. The medium seeds were germinated faster than heavy seeds and light seeds. Seed scarification gave effect on germination percentage and germination value significantly, but not significant on mean daily germination and ability to germinate. Seeds scarification with hot water at beginning temperature 80°C for 48 hours had germination percentage 28,000%, germination percentage was better than the scarification for 36 hours, 24 hours, 12 hours, and control

Pengolahan Limbah Cair Hotel Dengan Kombinasi Metode Elektrokoagulasi Dan Adsorpsi Menggunakan Karbosil
Get PDFThis study was carried out to investigate treatment of hotel wastewater using a combination of electrocoagulation and adsorption using carbosil prepared from rice husk with pyrolysis method. Electrocoagulation was applied with the aim to remove natural organic matter in the sample, using aluminim as electrodes, with the particular purpose to study the effect of potentials.The treated water was then subjected to adsorption process at different contact times and the performance of the process was evaluated in term of the reduction of the absorbance at maximum wavelength.The performance of the method was defined in term of absorbance reduction at the maximum wavelength of 226 nm, which was determined by scanning the original sample at the wavelength ranging from 200 to 700 nm.According to literature, the maximum wavelength of 226 nm is commonly assigned to benzene structure, most likely from the Alkyl Benzene Sulfonate (ABS) used in detergents.The results obtained indicate that for electrocoagulation process, the highest reduction in the absorbance was achieved using potential of 10 volt.Adsorption process was found to result in the diminish of peak at 226 nm, reflecting that the organic pollutant associated with this wavelegth has been completely removed from the water.Characterization of the carbosil using SEMtechnique revealed that the carbosil has practically homogeneous surface morphology, supporting its ability to adsorb the pollutants from the wastewater. Key words : adsorption, carbosil, electrocoagulation, hotel wastewate
Pemanfaatan Limbah Teh, Sekam Padi, Dan Arang Sekam Sebagai Media Tumbuh Bibit Trembesi (Samanea Saman)
Get PDFRain Tree (Samanea saman) has ability to absorb the carbon dioxide from the air. Due to it’s advantages, there was a need to know the propagation way. Using organic materials such as tea waste, rice husk and husk charcoal as a growing medium diggested could increase the seedling growth. This study aims to: (1) determined the effect of tea waste, rice husk and husk charcoal as a growth media for rain tree seedling (2) determined the best composition of the media among soil mixture with tea waste, soil with mixture rice husk and soil with mixture husk charcoal. The research was conducted from September 2012 to December 2012, in the greenhouse, Faculty of Agriculture, University of Lampung. The study was designed in completely randomized design (CRD) used 7 treatment with 5 replications, each consisted of 5 sample. Treatment consists of: 100% soil, soil + tea waste (75% + 25%), soil + tea waste (50% + 50%), soil + rice husk (75% + 25%), soil + rice husk (50% + 50%), soil + husk charcoal (75% + 25%), soil + husk charcoal (50% + 50%). Provision of tea waste, rice husk and husk charcoal was gave effect on canopy dry weight, stem dry weight, roor length, seed quality index and did not give affect on height and diameter of seedling, the appropriate composite media for each type of mixture was a composite soil + tea waste (75% + 25%), soil + rice husk (50% + 50%), of the soil + husk charcoal (75% + 25%)
Respon Pertumbuhan Bibit Jabon (Anthocephalus Cadamba) Dengan Pemberian Kompos Kotoran Sapi Pada Media Penyapihan
Get PDFKadam is one type of fast growing trees species. One of the factors that affect plant growth are nutrients, the use of organic fertilizer such as cow manure compost soil mix additive during planting can increase nutrient substances in the soil that plants need for growth. The purpose of this experiment was to study the growth response of kadam seedling at different mixing ratio betwen soil with cow manure compost at seedling growth media and the best comparison of soil mixed with cow manure compost where gave the best effect on the growth of kadam seedling. The experiment was conducted from March until June 2012 in the nursery PT Subur Anugrah Sejahtera, District of Kaur, Sub District Air Palawan. The method used in this experiment was randomized block design (RBD) with 5 groups and 5 treatments. Treatment of this experiment were growth media consisted of top soil, top soil + compost (1:1), top soil + compost (1:2), top soil + compost (1:3) and top soil + compost (1:4). Each experimental unit consisted of 10 seedlings. Similarity variety tested with Bartlett test, then performed analysis of variance and comparison of average values between treatments with HSD test, all the tests done at 5% significance level. The results showed that composition of soil and cow manure compost significantly affect to height, seedling height, dry weight of root, and seedling quality index. Composition of soil and cow manure compost 1:2 resulted the best of high growth, seedling high, dry weight of root, and the best seedling quality index respectively 42.64 cm, 40.56 cm, 10.22 g, and 8.73 g. For further research recommended to conduct the same study by replacing the type by cow manure compost white chiken manure compost as a growth media seedling so, can obtain new knowledge about the type of compost with for growth media
