Abstract

Increased phenotypic diversity is needed to increase the economic value of Aglaonema. However, information on increasing phenotypic diversity of Aglaonema using gamma-ray irradiation has not been widely known. This study aimed to investigate the effect of gamma ray irradiation treatment to the performances of two varieties of Aglaonema. This research was arranged factorially using randomized group design (RKLT) of two factors consisting of 8 combinations of treatments that are 4 level of irradiation dose and 2 Aglaonema varieties. The results showed that the induction of gamma ray irradiation decreased the % viable of the plants, the number of leaves, leaf length, leaf width, and the % green color as well as increased the % blue on the leaves of Aglaonema Butterfly and Aglaonema Siam Aurora. The interaction between dose of irradiation and aglaonema varieties was obtained in the % red of leaf color. Both of Aglaonema varieties had a high radiosensitivity with LD50 values ranged of 16.70 - 17.14 Gy

Abstract

The obstacle of chilli pepper development in saline is that there is no salinity tolerant variety, so it is necessary to assemble tolerant varieties. Information on tolerant genotypes, selection criteria and determination of new selection methods at the germination level are needed to make it easier for breeders to select prospective tolerant varieties early. This study aims to determine tolerant genotypes, appropriate selection criteria and NaCl concentrations used for selection at the germination level. The study was arranged based on a completely randomized design with two factors: NaCl concentration and some chilli pepper genotypes. NaCl solution concentrations consist of five concentrations of N0: 0 g L-1 (EC 291 µS/cm, SAL 0,10), N1: 2 g L-1 (EC 3,71 ms/cm, SAL 2,0), N2: 4 g L-1(EC 6,60 mS/cm, SAL 3,60), N3: 6 g L-1 (EC 9,56 mS/cm, SAL 5,40) and N4: 8 g L-1 (EC 12,45 mS/cm SAL 5,40). The second factor is the genotype of chilli pepper consisting of 22 genotypes. The results showed that the most tolerant genotypes were G4, G7 and G15. Characters that can be used as selection criteria at the germination level are the percentage of germination, radical and hypocotyl length. The concentration of 8 g NaCl L-1 is effectively used to select tolerant genotypes

Abstract

Water hyacinth is a type of plant that grows in freshwater environments. This plant is an ideal raw material to produce bokashi which increases the availability of soil nutrients. To maximize the function of the water hyacinth bokashi, a growth regulator is used to encourage plant upatake of soil nutrients. This study aimed to examine the single effect and interaction between water hyacinth bokashi (BHW) and plant growth regulators (PGR) on black rice. Data were analyzed with a factorial randomized block design. The first factor is WHB (B) 0 ha-1 and 2 t ha-1, while the second factor is PGR (Z) 0 ppm and 1.5 ppm. The results showed that the best effect of grain weight per hectare was treatment with WHB 2 t ha-1, PGR 1.5 ppm, and their interactions were 10.34 t ha-1; 11.09 t ha-1, and 12.16 t ha-1 harvested dry rice

Abstract

People of Kolaka accustomed to using coconuts as well be used as a food supplement or a mixture of additives in processed foods, cakes and other confectionary. Therefore utilizing coconut pulp as feed fish and poultry should be made to minimize the potential for household waste. Feed from coconut pulp is a transfer of science and technology to the people who are expected to help poor people to be productive. Fermentation is one method to process coconut pulp into feed ingredients. The fermentation process is done by using spores of Aspergillus niger. The fermentation process is done in stages, by aerobic fermentation followed by anaerobic fermentation (enzymatic process). In short the process of making feed "PA-BIO" from coconut pulp is: Dregs of coconuts added water, stirred and steamed. Cooled and then stirred together with a mixture of minerals, Aspergillus niger spores are added and stirred again until evenly distributed. The mixture was then fermented aerobically and unaerobically. Dregs fermented and then dried and packaged for later in packing. Based on the results of research that the utilization of coconut dregs as cattle feed and fish is potential. Miskiyah et al. (2006), increase protein content after fermentation of coconut pulp 11.35% to 26.09%, or by 130% and decreased fat content of 11.39%. The results also showed that the feed produced quite safe for livestock, namely the aflatoxin content 20 ppb. Feed from coconut pulp is also good for fish farming. Goenarso et al. (2002) on tilapia (Oreochromis niloticus L.), the faster fish growth with increasing the feed protein content of 25%, 30%, 35%, 40% and 45%.

Abstract

Pepper is an important crop in Indonesia because it is one of the country's foreign exchange sources because it is one of the export commodities. The availability of good plant materials will support increased production. Provision of growth regulators in vegetative propagation is very influential on the propagation of pepper plants. The purpose of this study was to determine the most effective combination of growth regulators for pepper cutting. This study was conducted using a randomized block design consisting of eight treatments namely Control (P1), metallic 2 mL L-1 water (P2), mastafol 2 mL (p3), Atonik 2 mL (P4), metallic 1 mL + Mastafol 1 mL (P5), metallic 1 mL + atonic 1 mL (P6), mastafol 1 mL + atonic 1 mL (P7), metallic 0.66 mL + Mastafol 0.66 mL + Atonic 0.66 mL (P8). Setek is grown on soil media: fuel husk: manure (2: 1: 1). The results showed that the best  Plant growth regulator  combination treatment for the growth of pepper cuttings was P7 (mastafol 1 mL L-1 water + atonic 1 mL L-1 water), which can be seen in the parameters of the number of roots, root length, root volume and number of shoots. The treatment of  Plant growth regulator  given did not significantly affect the character of leaf growth

Abstract

Salinity screening under hydroponic Deep Flow Technique (DFT) has not been widely studied, especially on the nature of rice tolerance to salinity stress. According to previous screening studies, this method was effective in distinguishing the nature of rice tolerance to salinity stress. However, they were tested only at generative phase. Therefore, evaluation on screening method with hydroponic DFT at all phases of paddy growth is essential. The objective of this study is to evaluate the filtering under hydroponic DFT at all paddy phase and to determine secondary character that support productivity which can be utilized as selection character in this screening process. The experiment was arranged with a complete nested group design with nested replication is the NaCl stress. There were 5 (Five) tested rice varieties and the stress environment consisted of three levels: 0, 60, and 120 mM of NaCl, all with 3 (three) replications. The nutrient culture screening was adapted to the modified Egdane method. The results showed that screening under hydroponic DFT was effective at the concentration of 60 nM of NaCl. The best selection character was yields per clump, number of productive tillers and total chlorophyll. The variety of Jeliteng, Ciherang and Inpari 34 of Salin Agritan, were classified as tolerant group. This hydroponic DFT Filtering method could be recommended as one salinity screening method for all paddy growing phases

Abstract

One of the efforts to increase mango production in Southeast Sulawesi is to produce high quality and high quantity mango seeds. Manure contains macro and micro nutrients that are important for plant growth and development as well as play a role in maintaining nutrient balance in the soil to improve soil properties. The aim of this study was to obtain the best manure doses applied with agrobost in improving the growth of Arumanis mango seedlings. This research was conducted in Kemaraya Sub-District of West Kendari District, Kendari City. The study design used was a randomized block design (RBD) with 6 treatments, namely: control (T0), 100 g (T1); 150 g (T2); 200 g (T3); 250 g (T4); and 300 g (T5) of manure per polybag. Each treatment was added with agrobost of 17 ml/polybag and replicated 5 times. The variables observed were plant height, stem diameter; number of leaves, and leaf area, at ages 1, 2, and 3 months after planting. The results showed that the manure added agrobost influenced the growth of Arumanis mango seedlings. The manure treatment with a dose of 150 g per polybag (T2) was the best treatment in improving the growth of Arumanis mangoes at 1, 2 and 3 months after planting. This was indicated by the plant height of 28,40; 30,94; and 32,82 cm, stem diameter of 0,44; 0,70; and 0,99 cm; and number of leaves 6,60; 7,20 and 9,00 strands were significantly higher compared to other treatments during the study

Abstract

Chrysanthemum (Dendranthema grandiflora) is an ornamental plant that has high economic value, including flowers that are in great demand at domestic or abroad.  As cut flowers, chrysanthemums are used for decoration and flower arrangements at weddings, and for opening new offices.  The quality of cut flowers depends on the appearance and durability of freshness. Flowers with prime quality have a higher sale value compared to low-quality cut flowers. To maintain the quality of prime cut flowers still need to be implemented several treatments, especially when the flowers are ready to harvest to the consumers.  The handling of post-harvest chrysanthemums is an important factor that is inseparable from the stages of cultivation and greatly influences the selling value and added value that will be obtained by farmers and traders. The use of pulsing and holding liquid during display will extend the chrysanthemum vase life. By implementing post-harvest chrysanthemums in accordance with handling procedures (SOP), chrysanthemums will be obtained that can meet quality standards and can provide added value for farmers and flower traders
