Abstract

Pertumbuhan dan produksi tanaman ubi kayu di Kalimantan timur masih rendah. Keadaan ini disebakan kesuburan tanah yang relatif rendah dan sumber genetik varietas ubi kayu yang dipakai bukan varietas unggul. Sedangkan permintaan eksportir terhadap bahan baku sebagai olahan hasil dan bioetanol sangat tinggi sehingga perlu dilakukan penelitian dengan menggunakan pupuk dan varietas unggul. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemupukan terhadap pertumbuhan dan produksi tiga varietas ubi kayu yaitu Kasesat, Darul Hidayah, dan Gajah. Percobaan lapangan dilakukan selama 9 bulan mulai dari bulan maret hingga desember 2017. Lokasi penelitian di Sangatta Selatan, Kabupaten Kutai Timur. Percobaan ini menggunakan rancangan  split plot (petak terpisah) yang disusun secara factorial, diulang sebanyak 3 (tiga) kali (R). Petak utama (PU) adalah varietas yaitu v1 (Kasesat), v2 (Darul Hidayah), dan v3 (Gajah). Anak petak adalah pupuk (P) yang terdiri dari P0 (Tanpa pupuk /control), P1 Pupuk Anorganik (800 Kg NPK/Ha), P2 Pupuk Organik (20.000 Kg Bokashi pupuk kandang ayam / Ha), P3 Kombinasi pupuk anorganik (800 Kg NPK/Ha) + pupuk organik (20.000 Kg bokashi pupuk kandang ayam /Ha). Hasil penelitian menunjukkan bahwa pupuk anorganik dan organic (bokashi) dan kombinasinya mampu menghasilkan umbi masing-masing 39,7 ton/Ha; 40,37 ton/Ha; dan 50,41 ton/Ha. Perlakukan pemupukan 3 varietas ubi kayu dapat meningkatkan produksi 14,41%; 22,52%; dan 52,99% dibandingkan dengan control. Diantara 3 varietas ubi kayu tidak berpengaruh nyata. Varietas Gajah relative tinggi produksinya sebesar 11,73% dibandingkan dengan kedua varietas lainnya.

Abstract

This research was a solution to free desease banana kepok yellow which was decrease the banana product in East Kalimantan. This research were devided three years and it would be continued. The first years seedling propagation free desease through tissue culture. The second years the seedling derived tissue culture which was planted on the field, until harvesting fruit product. The third years processing fruit product to several kind of industrial product. The aim of the first years research was the highest number shoot regenerated from the explant center of banana corm, which induction several combination treatment of plant growth regulator Benzyl Amino Purine (BAP) and Indole Butyric Acid (IBA). This research conducted at Tissue Culture Laboratory of Agriculture Faculty of Mulawarman University, from March until November 2015. This research was used Randomized Completely Block Design with two factors. The firest factor : BAP consist 3 level consentration were : 2,5; 5 and 10 ppm and the secon factor : IBA consist 3 level consentration were : 0; 1 and 2 ppm. So that all of combination of plant growth  regulator were 9 treatments. Each treatments were replicated ten times. Result of this research showed that all combination of concentration treatment of plant growth regulator BAP and IBA could be induce the growth and differentiation of explant center of banana corm in Murashige and Skoog (MS) media, like : inbibition, developed tissue of explant, callusing and shooting, although the percentage and totality was variation. The colour of callus was yellow and light green. While the structure was hard and compact. The highest average number of shoots induction at VII combination treatments BAP 10 ppm + IBA 0 ppm ware 3.80± 1,76 shoots/explant which was the root un completely development. So that it need sub culture to the rooting induction media with IBA 10 ppm to be formed completely plantlet (seedling), which could be survived on acclimatization processing.

Abstract

Several years ago at 2000 Kepok “Yellow” Banana plantation  in East Kalimantan was attached disease, so that the production was decrease therefor in vitro propogation was a preferred a n alternative method. The aim of this study was to knew the growth and disease resistance of Kepok “Yellow” Banana post acclimatization seedling in nursery giving trichoderma as a biological control technique. This study was conducted in April until July 2018 in Samarinda. The completely randomized factorial was used as experiemental design with two factor ie: giving trichoderma (T) consist two level : with trichoderma (T1) and without trichoderma (T0), another factor ie : giving Nasa liquid organic fertilizer (N), consist four level : N0  (0 ml/l water); N1 (2 ml/l water); N2 (4 ml/l water); N3 (6 ml/l water). So that became 8 treatments, each treatment were repeated for five times.The total population were 40 polybags. Each polybags was planted 1 seedling after post acclimatization  healthy and  strong.  The  parameter  observed    were  increase  of  plant  hight, number of leaves, length of the longest leaves, width of the widest of leaves and diameter of stem. Observation the parameter was every two weeks, except diameter of stem, wich was only the end of observation. Polybag was filled with a mixture of   top soil and goat manure with ratio 4:1. Trichoderma treatment T1 by providing trichoderma agent in mixture top soil. Treatment was done before the seedling planted in the polybag. The treatment of Nasa was done one for week. The result of research showed that the growth of banana seedling have significant different to the treatment of Nasa liquid organic fertilizer, wich was the best concentration N1 (Nasa 2 ml/liter of water. The effect of interaction giving Trichoderma and Nasa, to almost the all of growth parameter were not significant different, except in increase the length of leaves. Al trought it have tendency T1N1  the best effect to the growth of all observation. The proves that the Kepok “Yellow” Banana seedling from tissue culture were fertile growing and healthy without disease attack.

Abstract

Ulin (Eusideroxylon zwageri) is one of the native plants of Indonesia whose growth is spread in tropical forest, among others in southern Sumatra and Kalimantan. Based on the results of the 1998 Asia Regional Workshop meeting held at the Hanoi (Vietnam) International Union for Conservation of Nature and Natural Resources (IUCN), it was determined that ironwood is on Vulnerable A1cd + 2cd status which means sensitive or is facing a high risk of extinction. Tissue culture is a technique that needs to be applied to overcome the problem of ironwood regeneration initiation. However, the concentration of tannin with high concentration so that the formation of browning which leads to the death of ulin tissue is one of the causes of the low success of ironwood tissue culture. This study was formulated based on the potential of activated charcoal and vitamin C to overcome browning, so that it can significantly affect the growth of Ulin regeneration initiation (Eusideroxylon zwager). The analytical method used is Observation of Qualitative Parameter Treatment, namely explant color and the quantitative parameter observed is the number of explants that have browned and not browned in this case are calculated in percent. Based on the results of the research that has been done, obtained methods to overcome browning in ulin explants (Eusideroxylon zwageri) which is divided into 2 stages. In stage 1 (pre-condition) browning can be overcome with a 100% success rate, explants soaked for 24 hours in 50% MS liquid media with pH 4. In stage 2, browning can be overcome with a 100% success rate on 100% MS solid media addition of BAP 1.0 mg / L with A2B3 treatment (Vitamin C / 1 mg / L ascorbic acid, 4.00 g / L activated charcoal) placed in the dark room.
