The Effect of Culture Container and Carbon Source Concentration on In Vitro Shoot Propagation of Atlantic PotatoABSTRACTPotato is a food commodity that has the potential to support food diversification in Indonesia. There is an increasing demand for Atlantic potatoes as the raw material for processed potato products. The demand, which has not been met by the increased production, has been the cause of the ongoing potato import activities in Indonesia. The limitation of producing quality Atlantic potato seeds economically is one of the obstacles to increasing the production of Atlantic potatoes in Indonesia. The aim of this research was to study the effect of various table sugar concentrations as the carbon source and the type of the culture containers used for Atlantic potato shoot multiplication in vitro. The propagation was carried out in bioreactors and culture bottles with MS liquid medium + coconut water at a concentration of 150 mL/L medium, and 3 concentration levels of table sugar, namely 0; 7.5; and 15 g/L medium. The use of bioreactor significantly increased the height of the Atlantic potato plantlets. The use of bioreactor combined with table sugar addition decreased hyperhydricity level. The highest number of shoots, leaves, and roots were found at the table sugar concentration of 15 g/L medium in both containers.Keywords: bioreactor, micropropagation, shoot culture, Solanum tuberosum, sucroseÂ ABSTRAKKentang merupakan komoditas pangan yang berpotensi mendukung program diversifikasi pangan di Indonesia. Peningkatan permintaan terhadap kentang Atlantik sebagai bahan baku kentang olahan yang tak diimbangi dengan peningkatan produksi kentang Atlantik menjadi penyebab masih berlangsungnya impor kentang Atlantik di Indonesia. Keterbatasan menghasilkan benih kentang Atlantik berkualitas yang ekonomis merupakan salah satu hambatan dalam meningkatkan produksi kentang Atlantik di Indonesia. Penelitian ini bertujuan mempelajari pengaruh variasi konsentrasi sukrosa teknis sebagai sumber karbon dan penggunaan jenis wadah terhadap perbanyakkan tunas kentang Atlantik secara in vitro. Perbanyakkan tunas kentang Atlantik menggunakan media MS cair + 150 mL/L air kelapa dalam wadah bioreaktor dan botol kultur dengan 3 taraf konsentrasi sukrosa, yaitu 0; 7,5; dan 15 g/L media. Penggunaan bioreaktor secara signifikan meningkatkan tinggi planlet kentang Atlantik yang dihasilkan. Penggunaan bioreaktor yang dikombinasikan dengan penambahan sukrosa teknis menurunkan tingkat hiperhidrisitas. Tunas, daun, dan akar terbanyak dihasilkan oleh perlakuan sukrosa teknis 15 g/L media dalam kedua jenis wadah.Kata Kunci: bioreaktor, kultur tunas, mikropropagasi, Solanum tuberosum, sukrosa

Genetic Diversity of 22 Local Rice Accessions from North Toraja Based on Simple Sequence Repeats (SSR) MarkersABSTRACTOne way to explore the potential of local rice is by the characterization that could obtain genetic diversity of that plants. The aim of this study was to obtain the genetic diversity of 22 local rice accession from North Toraja. Twenty-two of local rice accessions from North Toraja were characterized by 30 SSR markers and using NTSYS pc 2.1 program to analyze genetic diversity. The results showed that twenty-six SSR markers that had been analyzed produced some alelles with a size between 106.75-311 bp, the average number of alleles were 3 and the polymorphism rate was 0.53. On coefficient genetic similarity at 0.38, the population formed three clusters. Cluster I and II were dominated by rice that had no hair on the tip of the grain and cluster III were dominated by rice that had hair on the tip of the grain. There were 105 opportunities to crossing between accessions when the genetic distance was above 0.7.Keywords: genetic diversity, local rice, North Toraja, polymorphism rate, SSR markersÂ ABSTRAKSalah satu cara untuk menggali potensi padi lokal adalah dengan karakterisasi.

Antioxidant Activity of Endophytic Fungi Cb.Gm.B3 Extract from CinnamonÂ (Cinnamomum burmanni) TwigsABSTRACTThere are many degenerative diseases that are caused by a free radical effect. Cinnamon (Cinnamomum burmanni) contains cinnamaldehyde compounds that have activity as a powerful antioxidant and fight free radicals. Endophytic fungi can be found in cinnamon plants living symbiotically. Endophytic fungi produce a variety of bioactive metabolites including antioxidants. This research was conducted to isolate endophytic fungi from C. burmanni plant which is active as antioxidant. Endophytic fungi isolation was carried out using surface sterilization method and cultivated in PDA media. Antioxidant activity test was performed using free radical 2.2-diphenyl-1-picrylhydrazyl (DPPH) method. Selected isolates were then identified molecularly to determine their species. A total of nine fungi were isolated from cinnamon twigs. The result showed that the highest antioxidant activity was obtained from Cb.Gm.B3 with IC50 of 13.219 Â± 0.755 Âµg/mL. The selected isolate Cb.Gm.B3 taxonomically has a high similarity with Neofusicoccum parvum isolate PEL23 (Accession no: KY053054.1).Keywords: antioxidant, Cinnamomum burmanni, 2.2-diphenyl-1-picrylhydrazyl, endophytic fungi, Neofusicoccum parvumÂ ABSTRAKKayu manis (Cinnamomum burmanni) mengandung senyawa sinamaldehid yang memiliki aktivitas sebagai antioksidan kuat dan dapat menangkal radikal bebas. Dalam tanaman kayu manis terdapat kapang endofit yang hidup bersimbiosis. Kapang endofit dapat menghasilkan berbagai senyawa metabolit bioaktif termasuk antioksidan.

Impact of Slicing and Moulding Techniques on the Floatability ofÂ the Fish Feed Fermented by Rhizopus sp.ABSTRACTThe use of Rhizopus sp. mycelium as biocoating, biostabilizing, and biofloating agent in the production of floating fish feed through solid fermentation had already been studied as a much simpler alternative to mechanical extrusion. The fermented fish feed, however, had poor floatability in aerated water, probably due to structural damage during the size reduction process of the feed. Thus, this study used alternative size-reducing methods, namely slicing and moulding, to improve the floatability of the fermented feed. Other physical characteristics were also measured and compared to those of commercial sinking and floating fish feeds. Results showed that both the moulded and the sliced fermented-feeds had lower density as well as higher water stability, absorption capacity, floatability, and durability compared to those of the commercial sinking feed used as the fermentation substrate. The hydrophobicity of all the feeds tested were similar, however. The floatability of the fermented feeds obtained in this study was much higher than those of the previous studies.Â Keywords: floatability, floating feed, sinking feed, water absorption, water stabilityABSTRAKPenggunaan miselium Rhizopus sp. sebagai pelapis permukaan, penstabil, dan pengapung hayati dalam pembuatan pakan ikan apung melalui fermentasi padat telah diteliti sebagai alternatif yang jauh lebih sederhana dibandingkan dengan metode ekstrusi mesin. Namun, pakan ikan fermentasi ini memiliki daya apung yang buruk dalam air bergelembung udara, yang mungkin disebabkan kerusakan struktural selama proses pengecilan ukuran pakan. Karenanya, penelitian ini menggunakan metode lain untuk mengecilkan ukuran, yakni pencetakan dan pengirisan, dalam rangka meningkatkan daya apung pakan yang difermentasi. Karakteristik fisik lainnya juga diukur dan dibandingkan dengan pakan ikan tenggelam dan terapung komersial. Hasil menunjukkan bahwa proses fermentasi serta metode pengecilan dimensi yang digunakan menghasilkan pakan yang memiliki massa jenis lebih rendah, serta stabilitas air, daya serap air, daya apung, serta ketahanan benturan lebih tinggi dibandingkan dengan pakan tenggelam komersial yang digunakan sebagai substrat fermentasi. Namun, nilai hidrofobisitas semua pakan yang diuji adalah sama. Daya apung pakan fermentasi dalam penelitian ini jauh lebih tinggi daripada penelitian sebelumnya.Kata Kunci: daya apung, daya serap air, stabilitas dalam air, pakan apung, pakan tenggelam
