To support the cultivation of yellow cempaka (Michelia champaca) intensively, high quality seedlings was needed. One of the factors that affect the growth and quality of seedling was growth media. The objectives of the research were to (1) determine the effect of saw dust and rice husk as growth media than the top soil for yellow cempaka seedlings; (2) obtained the best composite media between top soil with saw dust and rice husk as media for growth media for yellow cempaka seedlings. The research was conducted in greenhouse, started from January to April 2013. The experiment used Completely Randomized Design (CRD) with 6 treatments and 3 replicates, every experiment unit consisted of 6 yellow cempaka seedlings so the total number amounted to 108 seedlings. The treatment were number of medias (1) top soil; (2) saw dust; (3) rice husk; (4) top soil + saw dust 1:1; (5) top soil + rice husk 1:1; (6) top soil + saw dust + rice husk 1:1:1. Observed variables include high growth, diameter, number of leaves, root length, top root ratio, total dry weight and seedling quality index. The results showed that growth media of rice husk gave a good growth of yellow cempaka same as media top soil. Composite growth media that had a better growth of yellow cempaka seedling was composite growth media top soil + rice husk 1:1.
ABSTRAKUniversitas Lampung memiliki ruang terbuka hijau cukup luas dengan vegetasi yang beragam.Keberadaan ruang terbuka hijau memiliki manfaat yang cukup besar dalam pengendalian suhu dan kelembaban udara.Penelitian ini bertujuan untuk mengetahui pengaruh vegetasi di ruang terbuka hijau terhadap suhu, kelembaban udara, tingkat kenyamanan dan estetika.Penelitian ini menggunakan model rancangan acak kelompok lengkap dengan teknik Purposive sampling dan wawancara yang dilaksanakan pada bulan Februari 2015. Hasil dari penelitian menunjukkan bahwa suhu udara tertinggi pada pagi, siang dan sore hari adalah di lokasi lapangan sepak bola. Suhu udara terendah pada pagi, siang dan sore hari adalah di lokasi tegakan campuran. Kelembaban udara tertinggi pada pagi hari adalah di lokasi tegakan beringin, sedangkan siang dan sore hari berada di lokasi tegakan sengon buto. Kelembaban udara terendah pada pagi, siang dan sore hari berada di lokasi lapangan sepak bola. Berdasarkan indek suhu dan kelembaban (THI) lokasi lapangan sepak bola, tegakan sengon buto, tegakan beringin dan tegakan campuran termasuk dalam kategori tidak nyaman.Persepsi responden terhadap tingkat kenyamanan dan keindahan ruang terbuka hijau di lokasi lapangan sepak bola termasuk dalam kategori tidak nyaman dan kurang indah.Lokasi tegakan sengon buto, tegakan beringin dan tegakan campuran termasuk dalam kategori nyaman dan indah.Kata kunci: iklim mikro, kenyamanan, ruang terbuka hijau ABSTRACT University of Lampung has quite extensive green open space with the diversity of vegetation. The presence of green open space consider to have benefits to control the temperature and humidity. This research was aimed to know the influence of vegetation on the green open
This study analyzes the success of implementing a conservation village in obtaining environmental support in forest management in the Bukit Barisan National Park. This research uses a qualitative case study method, reinforced by a desk review of relevant research literature. Interviews and focus group discussions were conducted to gain a deeper understanding of how successful policy implementation was Conservation Village in economic and conservation-based community empowerment in the TNBBS area. The success of policy implementation is reviewed by analysis of marketing policies and further analysis using a matrix of environmental reactions to policy implementation. The study results indicate that marketing policies in terms of policy acceptance and adoption have failed/successful and in terms of strategic readiness, successful with the establishment of a conservation task force tasked with managing and monitoring forest products and implementing this conservation village agreement. The community is an important part of the policy. The village government fully supports being the implementer of the policy. It is manifested in the form of providing access and facilities and for NGOs to provide full support through the provision of budgetary resources and facilitators for training and counseling related to building awareness to save forests.
Rising urban development decreased the availability of topsoil for growing media. Therefore, it was necessary to study potential alternative media such as cocopeat. The objective of the study wasto know the optimum composition of cocopeat and soil for optimum growth of Paraserianthes falcataria and Intsia palembanica. The method used was a complete random design. Five treatments were applied to each seedling, included: A (100% soil), B (75% soil + 25% cocopeat), C (50% soil + 50% cocopeat), D (25% soil + 75% cocopeat) and E (100% cocopeat). Seedlings growth were analyzed using analysis of variance, followed by least significant different (LSD) test. Result showed that the 25% cocopeat compound was the most optimum composition for Intsia palembanica seedlings, while 25% and 50% of cocopeat composition was the most optimum for the Paraserianthes falcataria growth. Keyword : cocopeat, growing media, Intsia palembanica, Paraserianthes falcataria, seedling growth.
Kadam 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.
