This research has been carried out with a view to induce rooting andÂ plantlet formation, followed by acclimatization.Â Micro shoots of sugarcane cv. PS 881 were cultured on Murashige and Skoog medium supplemented with different types and concentration of auxins for root induction. This research conducted experimentally using a split-plot design. The main plots were three types of auxins, which consisted of IAA, IBA, and NAA. The subplots were auxin concentrations with four levels, i.e. 0 Î¼M, 5 Î¼M, 10 Î¼M, and 15 Î¼M. Significantly faster root emergence time and higher number of roots observed in the Murashige and Skoog basal medium supplemented with 10 Î¼M NAA. The best root length obtained in the Murashige and Skoog basal medium supplemented with NAA 0 Î¼M. Plantlets derived from NAA 10 Î¼M treatment showed the best performance during acclimation with a 100% survival rate. NAA at a concentration of 10 ÂµM considered to be the best treatment inÂ plantlet formation and acclimatization of sugarcane cv. PS 881. This study showed that the use of MS medium with 10 uM NAA is able to increase the growth of PS 881 sugarcane plantlets. The results of this study can increase the availability of high quality seedlings and increase national sugar production.

Nepenthes adrianii (Kantong Semar) merupakan tanaman endemik khas Gunung Slamet, termasuk dalam Convention on International Trade of Endangered Species (CITES) terdapat apendiks I (Tahun 2003) dan II yaitu tanaman ini tergolong hampir punah dan langka. Mengingat besarnya potensi yang dimiliki tanaman ini, maka perlu adanya upaya konservasi untuk mengembangkan dan melestarikannya. Penerapan bioteknologi kultur jaringan atau kultur in vitro merupakan solusi yang tepat untuk melestarikan dan mengembangkan tanaman ini. Kultur in-vitro digunakan untuk multiplikasi tunas dan pembentukan plantlet.Penelitian ini bertujuan untuk: 1) mempelajari pengaruh interaksi BAP dan NAA pada multiplikasi tunas: 2) menentukan konsentrasi interaksi BAP dan NAA yang paling baik untuk memacu multiplikasi tunas; 3) mempelajari pengaruh bahan penyangga eksplan dan NAA pada pembentukan plantlet kantong semar (Nepenthes adrianii); dan 4) menentukan jenis bahan penyangga eksplan dan konsentrasi zat pengatur tumbuh NAA yang paling baik untuk memacu pembentukan plantlet kantong semar (Nepenthes adrianii).Metode yang digunakan adalah metode eksperimental, penelitian ini terdiri atas 2 tahap yaitu multiplikasi tunas dan pembentukan plantlet. Tujuan penelitian pada tahap multiplikasi tunas adalah untuk perbanyakan tunas dan tujuan penelitian pada tahap pembentukan plantlet adalah untuk mendapatkan tanaman kecil yang sejati. Tahap Multiplikasi Tunas menggunakan Rancangan Acak Lengkap (RAL) pola faktorial dengan 2 faktor. Faktor I adalah konsentrasi BAP yang terdiri dari 4 taraf yaitu 0 µM, 5 µM, 10 µM, dan 15 µM, Faktor II konsentrasi NAA yang terdiri dari 4 taraf yaitu yaitu 0 µM, 0,5 µM, 1 µM, dan 1,5 µM. Tahap Pembentukan Plantlet menggunakan Rancangan Petak Terpisah (Split Plot Design) sebagai petak utama adalah bahan penyangga eskplan (P) yaitu: agar dan jembatan kertas saring, sedangkan sebagai anak petak adalah konsentrasi NAA yang terdiri dari 4 taraf yaitu 0 µM, 5 µM, 10 µM, dan 15 µM. Parameter yang diukur dalam multiplikasi tunas yaitu waktu muncul tunas, waktu muncul daun, waktu muncul akar, jumlah tunas, jumlah daun dan jumlah akar. Parameter yang diukur dalam pembentukan plantlet yaitu jumlah tunas, jumlah daun, jumlah akar, daun terpanjang, akar terpanjang dan tinggi tanaman. Data yang diperoleh dianalisis menggunakan Analisis Ragam (Anova : Analysis of Variance) dengan tingkat kepercayaan 95%. Pengujian F menunjukan hasil sangat nyata kemudian dilanjutkan dengan uji Beda Nyata Jujur (BNJ) untuk mengetahui perbedaan antar perlakuan.Hasil penelitian menunjukan bahwa pada tahap multiplikasi tunas terbaik didapat pada perlakuan interaksi BAP 10 mM dan NAA 0,5 mM. Tahap Pembentukan plantlet terbaik di dapat pada perlakuan interaksi bahan penyangga jembatan kertas saring dengan zat pengatur tumbuh NAA 5 mM dan 10 mM.

Micro-shoot growth is the first step in the potato microtuber formation. The main factors were known controlling microtuber formation including the media type, the concentration of sucrose, the type and concentration of plant growth regulators, temperature, and photoperiodicity. This research aimed to determine the influence of the t of cytokinin and its concentration on the micro-shoot formation of Granola cultivar of potato (Solanum tuberosum L.), as well as to determine the best cytokinin type and its concentration on micro-shoot formation of Granola cultivar potato (Solanum tuberosum L.). The research was experimental in a split-plot design. The main plot was the type of cytokinin (BAP and Kinetin), and the subplot was cytokinin concentration at five levels of concentrations, i.e., 0, 5, 10, 15 and 20 µM. This study replicated each treatment three times which resulted in obtaining 30 experimental units. The data obtained were then analyzed using an analysis of variance, followed by honest significant difference test at 95 and 99% levels of confidence. The results showed that the formation of micro-shoot of Granola cultivar of potato was controlled by the type and concentration of cytokinin used. The addition of 5‒15 μM of BAP was found to be the best treatments to stimulate micro-shoot formation of Granola cultivar of potato.

Agarwood (Aquilaria malaccensis) is an important species with high economic value and has many benefits, which led to an overexploitation in its natural habitat. An effort to both provides sufficient seedling for agarwood cultivation and conservation is therefore much needed. This study has been carried out with a view to determine the effect of media types and BAP concentrations in two steps cultivation system on agarwood microshoot induction. This was a two stage-experiments i.e., microshoots induction and optimizing shoot development. The research results showed that the interaction between different media type and BAP concentrations had no significant effect on agarwood microshoot induction. Subsequent culture on MS media without any BAP addition showed that explant derived from MS medium solidified with 2.5 gr. L-1 Phytagel produced 2.36 ± 0.48 shoots/explant and 3.69 ± 1.16 leaves/explant. In addition, explant derived from culture on MS medium supplemented with 4 µM BAP produced 2.28 ± 0.61 shoots/explant. This is for the first time the application of two steps culture system for Agarwood (Aquilaria malaccensis) has been deployed and how the habituation phenomenon is handled.

Potato is an important food crop in both developed and developing countries and it is the fourth most important food crop after wheat, maize, and rice. Potato production in Indonesia has decreased in recent years, mainly due to the use of low quality tuber seed. The objective of this research was to determine the effect of plant materials, types of nutrients, and planting density on mini tuber formation, as well as to determine the best aeroponics conditions for mini tuber formation of Granola cultivar of potato. This research has been carried out experimentally using a Split-split Plot Design. The main plot was planting materials which consisted of plantlet and knol. The subplot was the type of nutrition media which consisted of Farran nutrition, Otazu nutrition, and AB-commercial mix. The sub-sub-plot was planting density which consisted of 50, 75, and 100 plants/m2. The research results showed that knol planted in aeroponics system on AB-commercial mix at a planting density of 75 plants/m2 resulted in the best mini-tuber production. In this study, for the first time three important factors for potato mini-tuber production have thoroughly been investigated in Indonesia. This finding will be used by Kledung Horticultural Seed Garden, Temanggung, for mass production of high-quality mini-tuber seed, which in turn will provide sufficient tuber seed for the farmer in its surrounding areas. By increasing the production of high-quality tuber seed, it is expected that it will contribute to the improvement of potato productivity and increase Indonesian potato production.
