Bibit berkualitas E. pellita salah satunya diproduksi dari klon unggul dengan perbanyakan secara vegetatif, yakni stek pucuk. Terdapat hasil penelitian yang menunjukkan bahwa perbanyakan klon tertentu memiliki nilai keberhasilan hidup tertinggi dengan perlakuan tanpa menggunakan hormon tambahan. Oleh karena itu perlu dilakukan penelitian perbanyakan bibit stek E. pellita tanpa menggunakan hormon. Hasil analisa fisiologi stek pucuk E. pellita menunjukkan setiap parameter yang diamati yakni kandungan hormon IAA, nilai C-organik, dan nilai N yang diamati menunjukkan hasil yang tidak linear dengan perlakuan umur tunas. Hasil pengukuran panjang tunas, jumlah node, dan jarak antar node menunjukkan nilai yang linear dengan perlakuan umur tunas. Hasil pengamatan total hidup (Survival Rate), total berakar dan bertunas menunjukkan perlakuan umur tunas 18 hari memiliki nilai terendah dibandingkan perlakuan lain. Pada umur 2 MST menunjukkan perlakuan umur tunas 21 hari memiliki kemampuan pertumbuhan akar paling cepat dibandingkan perlakuan lain. Berdasarkan hasil pengukuran tinggi dan diameter umur 12 MST menunjukkan perlakuan tunas umur 21 hari memiliki pertumbuhan dan Survival Rate terbaik sehingga dapat menjadi dasar penentuan umur tunas dalam produksi bibit klon 148 skala operasional. \u0000Kata kunci: E. pellita, fisiologi, perbanyakan, hormon","PeriodicalId":402773,"journal":{"name":"Journal of Tropical Silviculture","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140993259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The successful exploitation of peatland prompted the Indonesian Government to develop the region through a transmigration program, providing new settlements for people from Java, Madura, and Bali islands who were initially have no experience cultivating peatland. Land suitability issues have resulted in surprises, stress, and a decline in livelihoods among transmigrant populations, particularly concerning the failures in agriculture, especially in cultivating rice, the primary staple food for Indonesians. This research aims to examine the sustainability of livelihoods, determine the conservation aspirations and perceptions of stakeholders, and present alternative land use scenarios. Four villages were selected as samples, including a local village (Buntoi), two migrant villages in peatlands (Basarang Jaya and Sabangau Permai), and one migrant village outside the peatland area (Karang Sari). Data were obtained through interviews and group discussions involving farmers, entrepreneurs, and government officials. The research findings indicate that agriculture on peatlands can be developed through three stages of evolution: the early period, transition and recovery period, and stability or failure period. The stability period may take a long time, up to 20 years, as experienced by farmers in Basarang Jaya. This study provides insights into the sustainability of livelihoods and land use aspirations in Central Kalimantan.

Covering an area of approximately 24,382.04 Ha, the study projects that around 5-10% of this area serves as the habitat for gebang, playing a crucial role in the local community's life as a source of carbohydrates, vegetables, building materials, ropes, and woven crafts. The objective of this research is to assess the vegetation of gebang (Corypha gebanga) using the quadrant sampling method to analyze the identified vegetation composition and parameters such as density, relative density, frequency, relative frequency, dominance, and relative dominance. The research findings reveal that in the tree stratum, there is a density value of 0.02/0.01 ha, with a relative density of 100%, a frequency of 0.88 plots/9 plots, a relative frequency of 100%, dominance of 52.03 m2/900 m2, and a relative dominance of 100%. Similarly, in the Sapling Vegetation (Belta) stratum, the density value is 0.18/0.0025 ha, with a relative density of 100%, a frequency of 0.77 plots/9 plots, a relative frequency of 100%, dominance of 169.91 m2/225 m2, and a relative dominance of 100%.

Eucalyptus seedlings did not pass the general requirements for normal seedlings for the criteria of straight stems and healthy seedlings. Eucalyptus seeds that do not pass the test can be retested after the seeds have been selected or the quality of the seeds has been improved.

Sampling measuring 20 m x 20 m was placed by purposive sampling at 1.250, 1.350, 1.450 m asl, and open area (1.200 m asl) for vegetation analysis and subplots were carried out by purposive sampling on three sample subplots measuring (1 m x 1 m) for soil samples and environmental factors. The highest soil fauna was found at an altitude of 1.350 m asl (265 individual / m2) and the lowest was in the open area (11 individual / m2). The different test results showed that the altitude of 1.250 and 1.450 m asl was not significantly different, while the altitude of 1.350 m asl and in open area showed a significant difference. The relationship between the population of soil fauna and climatic factors such as ambient temperature and sunlight intensity has a negative correlation value, while humidity shows a positive correlation value.
