“…GA 3 soaking period for 3 days is suspected to be unable to break dormancy and the kernel has not been able to absorb water properly, so the water content in the kernel is not met causing the germination process to be hampered. This is in line with [27], the water content needed by palm seeds in the germination process is 22-24% The results of [28], soaking teak seeds for 9 days with atonic solution resulted in faster germination of 5 days after germination compared to 6 days of soaking 10.67 days after germination.…”

One of the main oil palm seed dormancy factors is the shell thickness. This could influence the germination homogeneity and required more time for oil palm seeds to germinate evenly. There will be such alternatives to improve oil palm seed germination as shell-less oil palm seeds or kernels which were soaked at different duration time and GA3 concentration. The objectives of this research was to evaluate germination rate of kernels under different soaking time and GA3 concentration. This study was conducted on Laboratory Plants Seed and Breeding, College of Agriculture, University of Lampung from June 2019 to September 2019. Treatment was arranged by factorial (6x3) in a randomized completely block design (RCBD) with 3 replications. The first factors were the six different concentrations of GA3 hormones as 0, 100, 200, 300, 400, and 500 ppm. The second factors were the three different soaking duration as 3, 7, and 10 days. The variables observed were the percentage of germination, the maximum growth potential, early time of germination, germination rate, dormancy intensity, radicle and plumule lengths. The data were analyzed by analysis of variance and then different mean values of treatments were analyzed by 5% of LSD using the SAS software application (version 9.4). The results showed that the concentration of 200 ppm GA3 resulting in low dormancy intensity (12.22%), increasing potency maximum growth (87.78%), and kernels germination rate (8.44%/etmal) compared with a concentration of 0 ppm GA3. Soaking duration of GA3 10 days resulted in low dormancy intensity (17.22%), the percentage of germination increased (23.33%), the maximum growth potential increased (78.89%), the kernel germination rate (8.94%/etmal), radicle length (2.00cm), plumule length (1.92cm), and early time of germination (4.61days) compared to the length of soaking duration of 3 days.

“…Penambahan HCl dalam perendaman benih jati sebelum penyemaian sangat dibutuhkan karena struktur benih jati yang sukar ditembus air. Srilaba et al (2018) menyatakan bahwa buah jati merupakan buah batu dengan struktur buah yang terdiri dari kulit luar tipis (exocarp), lapisan tengah (mesocarp) yang tebal seperti gabus serta bagian dalam (endocarp) yang keras dan bergerigi). Tinggi tanaman jati menunjukkan hasil lama perendaman yang tidak berbeda nyata diduga disebabkan oleh benih jati yang telah jenuh oleh air.…”

“…Parameter tinggi tanaman menunjukkan hasil yang paling tinggi dengan perlakuan konsentrasi HCl 0.5 M dan 1 M yaitu sebesar 13.17 cm dan 13.22 cm. Menurut Srilaba et al (2018) tinggi kecambah jati umur 60 hst paling tinggi dengan lama perendaman 12 hari yaitu 14.56 cm sedangkan terendah dengan lama perendaman selama 6 hari yaitu 10.85 cm pada perendaman menggunakan atonik. Perlakuan perendaman benih memerlukan berbagai pertimbangan dalam menentukan lama waktu yang digunakan.…”

Teak is a wood-producing plant that is in great demand by the community. However, teak seeds are challenging to germinate due to dormancy, so special treatment is needed before planting. This research aimed to determine the effect of hydrochloric acid and soaking time on breaking the dormancy of teak seed to improve its viability. The first factor was the concentration of hydrochloric acid with four treatment levels, i.e., 0 M, 0.5 M, 1 M, and 1.5 M. The second factor was submerging time which was 12, 18, and 24 hours. Parameters observed included the percentage of germination, maximum growth potential, vigor index, germination rate, growth simultaneity, plant height, number of leaves, and wide leaf. The data obtained were analyzed statistically using ANOVA and followed the DMRT test with a level of 5%. The results showed that hydrochloric acid significantly affected the percentage of germination, maximum growth potential, vigor index, germination rate, growth simultaneity, plant height, and width of the leaf. In addition, soaking time treatment had a significant effect on the wide leaf. The research concluded that hydrochloric acid 0.5 M and 12 hours of soaking time increased the growth of teak seed compared to the control by 29.64% on a percentage of germination, 29% on germination rate, and 41.66% on growth simultaneity.

“…Selain bisa menambat nitrogen, bakteri Azospirillum juga dapat menghasilkan fitohormon atau zat perangsang tumbuh seperti sitokinin, auksin, giberelin, asam absisat, asam traumalin, dan etilena (Utama, 2011). Atonik atau sodium nitrophenolate dapat merangsang pertumbuhan tanaman, termasuk mempersingkat dormansi biji ulin (Purba et al, 2019) dan biji jati (Srilaba, Purba, Arsana, 2018).…”

Planning is important in carrying out an activity or activity, especially development activities. Planning is an effort in selecting and linking facts and making and using assumptions about the future by describing and formulating the activities needed to achieve the desired outcome (Susanto, 2016). Rejang Lebong Regency is one of the Regencies in Bengkulu Province that is included in the zone for the development of the Coffee Agribusiness area. Planning for the development of the coffee area was arranged by the Bengkulu Provincial Government. This study aims to examine the concepts related to coffee area development planning. The research method used is based on a literature review. From the results of the Literature study it was found that planning for the development of the coffee area in Rejang Lebong Regency should be carried out in accordance with considering the condition of the land, weather and climate of the region in Rejang Lebong Regency.. Abstrak: Perencanaan adalah hal yang penting dalam melakukan suatu kegiatan atau aktvitas , terutama aktivitas pembangunan. Perencanaan adalah suatu upaya dalam memilih dan menghubungkan fakta- fakta dan membuat serta menggunakan asumsi - asumsi mengenai masa yang akan datang dengan jalan menggambarkan dan merumuskan kegiatan - kegiatan yang diperlukan untuk mencapai hasil yang dinginkan (Susanto, 2016). Kabupaten Rejang Lebong adalah salah satu Kabupaten di Provinsi Bengkulu yang masuk di dalam zona untuk pengembangan kawasan agribisnis Kopi. Perencanaan untuk pengembangan kawasan kopi di susun oleh Pemerintah Provinsi Bengkulu. Penelitian ini bertujuan untuk mengkaji konsep yang berkaitan dengan perencanaan pengembangan kawasan kopi. Metode penelitian yang digunakan berdasarkan kajian literature. Dari Hasil studi Literatur di dapatkan bahwa perencanaan pengembangan kawasan kopi di Kabupaten Rejang Lebong sebaiknya dilakukan sesuai dengan mempertimbangkan kondiri lahan, cuaca dan iklim kawasan di Kabupaten Rejang Lebong.agar dapat menghasilkan produksi yang optimal.
