Abstract

Nyamplung (Calophyluminophylum) merupakan salah satu jenis tanaman yang dikembangkan sebagai tanaman penghasil biofuel. Penanaman nyamplung banyak mengalami gangguan berupa serangan hama trips (Heliothrips haemorrhoidalis Bouche) dan hama penggerek pucuk. Upaya pengendalian hama terpadu ditekankan pada pengurangan penggunaan insektisida sintesis dengan penggunaan insektisida nabati. penelitian ini bertujuan untuk mengetahui efektfitas beberapa jenis insektisida terhadap hama trips dan penggerek pucuk. Penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri dari 3 perlakuan (kontrol, insektisida kimia dan ekstrak daun sirsak). Setiap perlakuan di ulang sebanyak 30 kali, sehingga total tanaman sebanyak 90 tanaman. Hasil penelitian menunjukkan bahwa Ekstrak sirsak efektif menurunkan tingkat kerusakan hama penggerek pucuk sampai 10% sedangkan insektisida kimia efektif menurunkan tingkat kerusakan hama trips sampai 85%.

Abstract

ABSTRACTInterests on biochar application for the improvement of soil properties and fertily are increasing worldwide nowadays and numerous of production techniques are now available. This research was aimed at the investigation (a) on the characteristics biochar produced by 3 (three) different techniques, i.e: (1) traditional soil pit, (2) retort closed drum and (3) open drum kilns, as well as (b) on growth (height, leaf number and survival) response of Shorea leprosula seedling to 20%v biochar application on bioassay trial in the nursery. Bioassay trial was carried out in nursery of Forestry Faculty of Mulawarman University, Samarinda, Indonesia and was in accordance with Completely Randomized Design (CRD) applying 4 treatments and 3 replications.Of those 3 production techniques, retort closed drum kiln production technique was the most promising for further development and adoption providing not only that the biochar produced gave better properties and soil improvement capacity but also higher production recovery and less time and labour involvement. Furthermore, eventhough it was not statistically significant, biochar produced by retort closed drum gave better growth (height and leaf number) rate to S. leprosula seedlings in bioassay trial compared to those given by biochar produced by other techniques and without biochar treatments.

Abstract

Biomass studies are important because they are closely related to other study interests. Estimation of the amount of forest stand biomass is highly relevant to the study of biogeochemical cycles. This study aims to determine the amount of biomass and macro nutrient content in teak stands. By calculating the biomass estimation and analyzing the nutrient content it will be known the amount of nutrient accumulation in biomass. The results of this study are: Total of teak stand biomass of 39,26 ton / ha, including stem component as much as 21,64 ton / ha (55%), branch + twig 11,79 ton / ha (30%), bark component 3.71 ton / ha (9%) and leaf component 2.13 ton / ha (5%). The highest N concentration of nutrients in leaf components, for the highest P in branches + twigs, whereas K, Ca and Mg were highest in the bark component. The highest accumulation of nutrient biomass is Ca (194.4 kg / ha), followed by K (189.7 kg / ha), P (92.4 kg / ha), N (53.5 kg / ha) and Mg (48.4 kg / ha).

Abstract

The pathogen attacks the host plant in various ways to obtain the food substance needed by the host pathogen. To get into the host pathogen is able to break the host's defense reaction. The aim of the study was to know the symptoms and signs of stem rot disease in E. pellita in the nursery. In addition, also to determine the frequency and intensity of rodent pathogen attack in plant seeds E. pellita from shoot cuttings. Research in the nursery begins by determining the sample of plant seeds to be observed. Seed determination is done by census. Seedlings consisted of 120 plants in a plastic rack that was repeated as many as 3 replications so that the total number of seedlings observed was 120 plant seed x 3 replicates x 4 families = 1.440 plant seeds. The pathogen that causes stem rot on E. pellita seed is Fusarium sp which is transmitted through soil.
