Abstract

Sulphur Potential of Water Hyacinth {Eichhornia crassipes (Martt.) Solm} Bokashi in Improving The Quality and Yield of Rice in Inceptisols. The objectives of research were to find out sulphur potential of  hyacinth bokashi in improving the quality and yield of rice in Inceptisols. The experiment was conducted from April 2012 to October 2012 in a Greenhouse of Faculty of Agriculture, Padjadjaran University, Subdistrict Jatinangor, Regency Sumedang, West Java Province, at elevation of 782 m above sea level. Randomized Block Design (RBD) was used factorial pattern and repeated three times. The first factor was the dosage of sulphur (S) fertilizer consisted of : without S fertilizer; 20; 40; and 60 kg ha-1 S fertilizer, and the second factor was dosage of water hyacinth bokashi (B) consisted of: without bokashi; 15; 30; and 45 t ha-1 bokashi. Water hyacinth {Eichhornia crassipes (Martt.) Solm} bokashi is a superior organic matter with an excess of element sulphur.  The preliminary experiment result interaction between sulphur fertilizer and water hyacinth bokashi on total S, available SO42-, total N, C-organic, available P,  Zn, uptake S, N and yield effect occurred between give an  uptake P but not significant on Fe and uptake P.  The independent influence sulphur fertilizer and water hyacinth bokashi effect on soil availableP.  The analysis respons optimum dosage of sulphur was 45.52 kg ha-1 and bokashi water hyacinth was 35.99 t ha-1  to yield of rice plat obtained was 9.27 t ha-1.  Multiple regretion between respons parameters with yield of rice plant obtained was  available P, uptake P, and available SO42-, gave efffect to yield and R2 = 0.70**, 70 percent gave significant contributions to yield by available P, uptake P, and available SO42 on Inceptisols.

Abstract

The effectiveness of some modes of mosaic virus transmission in chili plants.  This study aims to determine the persistence of the mosaic virus in chili and techniques as well as effective mosaic virus infection on chili plants. The experiment was conducted for about four months from land preparation up to the last data collection. Research conducted at the Green House Agronomy Faculty of Agriculture, University Mulawarman. Research and laboratory tests carried out on 35 samples of chili fruit crops, which consists of 25 pieces of diseased plant samples and 10 samples of healthy plants. The results showed that the cause of the mosaic disease in pepper caused by viruses, which dibuktikakan with some testing include: watering with tetracycline antibiotics for 10 days on diseased plants did not show symptoms of healing. Grafting (grafting) between healthy and diseased plants plants rnenunjukkan healthy plant mosaic experience symptoms at week 4 (the virus moves through the vascular tissue). Vector Myzus persicae were introduced into healthy plants for 7 days successfully transmit the virus to healthy plants that exhibit the same symptoms on day ll. Mechanical transmission is not successfully transmit the virus to healthy plants until day 4 after inoculation. The most effective method of infection is by using subsequent grafting by using insects. Meanwhile mosaic virus transmission by mechanical means is not effective because there are no infected plants after mechanically inoculated.

Abstract

The results of the research showed that the forest of Wosi Rendani protection has slope 21.9% (score 60), soil type podsolic/ ultisol (Score 60) and 12.86 rain intensity (score 10), altitude 210 m asl,  with a total score of 130 as a buffer zone.  Perceptions of respondents unanimously positive 64.17% and 75% attitude towards local community-based management. This is due to the location of protected areas that are near human settlements and local immigrant who feared if the protected forest next to landslides and people lack of clean water.  Inside the forest, there is an object HLWR areas and attractions such as waterfalls, caves, springs, pools that can be used as the establishment of protected forest.  Protected forest of Rendani Wosi area has considerable potential to support regional management efforts such as the potential for flora and fauna, water, waterfalls and springs and caves as well as the support of the community around the area, but the legality of the area there has been no major obstacles in the management of this protected forest

Abstract

Pest and Disease Identification Shorea leprosula Miq in Kutai National Park Resort Sangkima East Kutai regency of East Kalimantan Province. The purpose of this study were: (1) To determine the frequency of pest and disease types meranti Shorea leprosula Miq. (2) To determine the intensity of pests and defect types meranti Shorea leprosula Miq. (3) To determine whether or not the prevention and control of pests and plant diseases meranti types Shorea leprosula Miq. This research was conducted in the Kutai National Park Resort Sangkima East Kutai in East Kalimantan Province. This study was conducted for two months effective the month of August 2012 until September 2012.The results of the research area of 1 ha with observations census found 11 Shorea leprosula Miq trees, with one tree physically healthy, 8 mild stricken trees, one tree is being attacked, and 1 heavy stricken trees. Arise and the presence of pests and plant diseases are often referred to as crop pests on crops and forests natural forests are mostly human intervention. From the calculation of the frequency of attacks on research plots by 91%, which means that almost all types of Shorea leprosula Miq indicated no pests and diseases while 9% were healthy. From the calculation of the intensity of pests and diseases of plants Shorea leprosula Miq, including the intensity of the attack was broken by 29.5%. Based on the identification of some pests and fungal diseases like cancer, stem, leaves and termite holes. The research concluded that the frequency of pest and disease Shorea leprosula Miq by 91%, the intensity of pests and diseases of the damaged condition of the stand, including 29.5% with the intensity of the attacks, control of pests and plant diseases do not need to be done because the condition only affected stands were . Recommended based on observation of pests and diseases types Shorea leprosula Miq need for monitoring human activities that can lead to new pests and diseases in forests Resort Sangkima which can reduce the quality and growth of the forest it self.
