Abstract

The objectives of this study is to investigate the effect of (Urea) and Polymer Coated Urea (Slow Release N - Fertilizer) on the growth and quality of turf Bermuda grass (Cynodon dactylon var. Tifdwarf.) and to find the optimum rate. Treatments are urea and PCU rate at 4.5 g, 9.0g and 13.5 g N/m2/application, respectively. The experiment was arranged in Randomized Block design with 3 replications. Fertilizers were applied 6 times in every 2 locals. The result showed that in the end of the experiment, the higher values of grass height. number of shoots resiliance. Fresh and dry weight were obtained with PCU /3.5 g N/m2/application. The highest dosage of PCU resulted d the highest quality of turf grass.   Key words: Urea, Polymer Coated urea, Bermuda grass

Abstract

Greenbelt and green infrastructure are still very limited in Jakarta. Transjakarta Corridor 8 Harmoni - Lebak Bulus covers Central Jakarta, West Jakarta, and South Jakarta which are government centers and densely populated settlements. The high activity in the area causes an increase in transportation flows and greenhouse gas emissions. The transportation sector is the highest contributor to CO2e emissions in the capital city, thus reducing environmental quality, especially the greenbelt in Transjakarta Corridor 8. The assessment of ecological functions in this study consists of 7 variables, namely noise reduction, pollution reduction, air humidity, view control, glare control, direction and accident prevention. The research location is divided into 5 segments with the analysis method used, namely the assessment of ecological function aspects and the formulation of recommendations based on Hierarchical Process Analysis. The results of the assessment on ecological functions with noise-canceling variables were (Polyalthia longifolia) Glodongan Tiang, (Casuarina sp.) Spruce, (Acacia auriculiformis) Acacia, and (Archontophoenix alexandrae) Alexander Palm. The results of the pollution reduction assessment of each segment are dominated by vegetation types (Mangifera indica) Mango, (Polyalthia longifolia) Glodongan Tiang, (Carbera odollam) Bintaro. Based on the results of the questionnaire, the AHP assessment weight was obtained. The combined AHP results show the highest priority scale for the evaluation recommendations of this research is Pollution Reduction as the most important variable with a weight of 0.348, the second rank is Accident Reducer with a weight of 0.300, the third rank is Glare Control with a weight of 0.150. The combined results of 3 experts produce a consistency ratio value of 0.05, the consistency ratio value of 0.05 is smaller than 0.10 so it can be said to have met the consistent requirements. Keywords: analytical hierarchy process, emission, roadside greenbelt

Abstract

The Al-Muhajirin Foundation has an elderly Islamic boarding school located in Abun Bunyamin Mukhtar (ABM)Far m, Gardu Village, Kiarapedes District, Purwakarta Regency. The Islamic boarding school's landscape has 4hectares of agricultural land planted with various horticultural crops, including fruit and vegetable crops.Besides elderly boarding school activities, ABM farm is also used as a venue for management meetings, outingclasses, English camps, tahfidz camps, Friday-Saturday camps, and training for students and administrators. Oneinnovation that can support academic and spiritual activities for users is implementing a healing garden. Thisactivity aims to share knowledge about healing garden and provide healing garden design suggestions of ABMfarm to administrators, students, and the community so that they can apply them in school gardens and theirrespective residential environments. The stages used in this activity are 1) Preparation; 2) Inventory; 3) Analysisand synthesis; 4) Concept development; 5) Design creation; 6) Implementation; and 7) Dissemination. Theresults of the healing garden development is a relaxation garden, a toga garden (family medicinal plants), andan edible garden, are effective in providing a space for discussion, murojaah, horticultural plant cultivation, andrecreation for students, teaching staff, administrators, and visitors. During the construction of garden anddissemination, the community was enthusiastic about planting aromatic plants, listening to the material, activelyasking questions, and answering the pre-test and post-test well. The post-test results showed that the lecturer'sreturn home activity increased the community's knowledge about healing garden.
