Abstract

ABSTRAK Penelitian ini bertujuan untuk menemukan sikap siswa terhadap penilaian yang diberikan oleh dosen dalam mata kuliah translation. Penelitian ini merupakan penelitian kualitatif, responden yang dipilih dalam penelitian ini adalah mahasiswa tahun ketiga pada tahun akademik 2011/2012 yang terdiri dari 12 kelas. Teknik pengambilan responden yang digunakan adalah Purposive Random Sampling. Jumlah responden yang diambil pada penelitian ini berjumlah 120 mahasiswa dan beberapa dosen yang sudah pernah mengajar mata kuliah translation. Instrumen dari penelitian ini adalah wawancara dan angket. Berdasarkan data yang didapat selama peneliti melakukan wawancara dengan beberapa dosen yang sudah pernah mengajar mata kuliah translation dapat diketahui bahwa tipe-tipe penilaian yang mereka berikan meliputi Free Response Items, True False Items, Matching,  Portfolio, Translation Production Test (Essay) dan Multiple Choice. Kemudian setelah peneliti menganalisa hasil jawaban mahasiswa terhadap angket, peneliti menemukan bahwa persentase mahasiswa yang mempunyai sikap positif terhadap penilaian yang diberikan dosen dalam mata kuliah translation adalah 36,80% dan persentase mahasiswa yang mempunyai sikap negatif adalah 63,20%, sehingga disimpulkan bahwa kebanyakan  mahasiswa masih salah dalam menyikapi penilaian dalam mata kuliah translation. Hal ini dikarenakan mereka sering merasa takut, cemas, khawatir, tidak percaya diri, bingung serta kurang termotivasi dalam melaksanakan  latihan yang diberikan dosen.

Abstract

This experiment was conducted to reveal genetic diversity among 38 genotypes of sugarcane (Saccharum officinarum L.) using RAPD markers. The population consisted of 8 genotypes from Australia, 7 from Africa, 10 from America, and 13 from Asia. Genetic similarity was ranging from 17% to 97% , with the average of 57%.  UPGMA dendrograms divided the population into three major groups i.e. group 1, 2, and 3 which consist-ed of 23, 10, and 5 genotypes, respectively. Each major group comprised genotypes of different geographical origins. The dendrogram divided each group into some subgroups. There were 8 subgroups i.e. 4 subgroups in group 1, 2 sub-groups in group 2, and 2 subgroups in group 3.  Some genotypes of same geographical origin were clustered into in at least 3 different sub-groups, meaning that they were genetically dis-similar. On the other hand, some other geno-types of different geographical origin were clustered into the same subgroup, meaning that they were genetically similar. This data would help sugarcane breeders to select parents for hybridization in order to maximize heterosis. This could be conducted by selecting parents of dis-similar genotypes.

Abstract

In an attempt to obtain a cost-effective and a simpler way of growing Dendrobium seedling in vitro, this study was conducted to investigate effects of basal media and organic additives on in vitro growth of Dendrobium seedlings.  The basal media used were that of half strength Murashige and Skoog (½ MS medium) and that containing foliar fertililizer 32:10:10 and trace elements (FT medium). Treatments were combinations of basal media (1/2 MS medium and FT medium) and different kinds of organic additive (tomato, potato, and mungbean sprout juice and banana homogenate). The experiment was conducted in a completely randomized design with three replicates, 5 culture vessels per replicate and 4 seedlings ca. 1.5 cm per vessel.  The experiment showed that FT medium resulted in significantly higher growth than ½ MS medium as indicated by seedling fresh weight.  The media containing tomato juice led to highest growth of seedling as shown by seedling fresh weight and seedling height. Since FT medium caused better growth than ½ MS medium, the FT medium could be used as a substitute for ½ MS medium for growing Dendrobium hybrid seedlings. The seedlings were successfully acclimatized in a shaded green house environment with 100% survival rate.

Abstract

The aim of this study was to observe responses of two banana cultivars ‘Ambon’ and ‘Raja Bulu’ on different BA concentrations and effects of different media and fertilizer on survival and growth of plantlets.  Sterilized explants were cultured on initiation medium (MS with 1mg L-1 BA) for 4 weeks, then subjected to media MS with 2.5, 5.0, or 7.5 mg L-1 BA. Numbers of shoot buds, shoots and propagules were recorded after 4 consecutive passages with 4 weeks intervals.  Rooted plantlets were acclimatized in three different media, then treated with or without NPK (32:10:10) fertilizer solution once a week. After 2 months, the survival and growth of plantlets were recorded. Cultures of banana ‘Ambon Kuning’ showed higher regenerative capacity compared to ‘Raja Bulu’, producing higher numbers of shoot buds, shoots and propagules. The best medium for propagule proliferation of both banana cultivars was MS+5 mg L-1 BA, producing 40.7 propagules for ‘Ambon Kuning’, and 12.3 propagules for ‘Raja Bulu’ per explant. In all acclimatization media tested, 100% of plantlet survival was achieved. The best plantlet growth was found in sand: compost (1:1,v/v) with application of NPK solutions. The in vitro-derived plants were planted in the field and produced fruits of high quality.

Abstract

Optimization of planlets growth during acclimatization can be done by using plant growth regulator. This research was aimed to know the effect of two foliar fertilizer and benzyladenin on the growth of Phalaenopsis hybrid orchid planlets during acclimatization stage. The treatment was Growmore and Bayfolan as the foliar fertilizer with the various concentrate of benzyladenin (BA) at BA 0 mg/l, BA 15 mg/l and BA 30 mg/l. The results showed that Growmore foliar fertilizer had the better response of plant height and fresh weight plant compared to Bayfolan foliar fertilizer. BA 30 mg/l was increased the leaf number, and BA 15 mg/l and 30 mg/l was decreased root length and fresh weight plant. There was no interaction between foliar fertilizer and benzyladenin on the growth of Phalaenopsis hybrid orchid planlets
