Rising urban development decreased the availability of topsoil for growing media. Therefore, it was necessary to study potential alternative media such as cocopeat. The objective of the study wasto know the optimum composition of cocopeat and soil for optimum growth of Paraserianthes falcataria and Intsia palembanica. The method used was a complete random design. Five treatments were applied to each seedling, included: A (100% soil), B (75% soil + 25% cocopeat), C (50% soil + 50% cocopeat), D (25% soil + 75% cocopeat) and E (100% cocopeat). Seedlings growth were analyzed using analysis of variance, followed by least significant different (LSD) test. Result showed that the 25% cocopeat compound was the most optimum composition for Intsia palembanica seedlings, while 25% and 50% of cocopeat composition was the most optimum for the Paraserianthes falcataria growth. Keyword : cocopeat, growing media, Intsia palembanica, Paraserianthes falcataria, seedling growth.

Mushroom growing media waste (MGMW) is the media waste after mushroom plants are harvested. In this research, we try to reuse MGMW as a material for composite particle board. The physical properties of the composite were tested using density and moisture content measurement. We also did the measurement for thickness swelling after immersion in water, the strength of absorption water, internal bonding. The mechanical test was conducted to know the modulus of elasticity, modulus of rupture and screw holding power properties. Impact and pressure was done for the optimum composition. The optimum composition, particle board is 75% MGMW + 24% polyester resin + 1% catalyst Mekpo (methyl ethyl ketone peroxides), and 60% MGMW + 39% (50% urea +50% starch) + 1% PVC glue. It is suitable for physical and mechanical test and accordance with SNI 03-2105-2006 and JIS A 5908-2003. The microstructure of MGMW was observed using Scanning Electron Microscope (SEM) shows the grain of a composite particle board is firmly integrated.

A comparison was made of Philippine coconut coir dust and Canadian spaghnum peat as components of three growing media for greenhouse production of Dieffenbachia maculata `Camille'. The soilless media were prepared using coir or peat in various amounts (by volume) combined with pine bark, vermiculite, and/or perlite (Media A–50% coir/peat: 25% vermiculite: 25% perlite; Media B–40% coir/peat: 30% vermiculite: 30% bark; Media C–50% coir/peat: 50% bark). Chemical and physical properties of the soils were determined at the beginning and the end of the five-month production cycle. Plant root and top growth and grades were determined at the end of the experiment. Initially, saturated media extracts from coir-containing media had elevated K, Cl, and soluble salts levels compared to peat-containing media; however, by the end of the experiment those levels were lower in coir- than in peat-based media. Water-filled pore space and water-holding capacities were generally higher and air-filled pore space lower in coir- than in peat-based media, probably due to differences in particle size distributions. There were no interaction effects on plant growth between growing media and coir versus peat. Plant root and top growth in Media A > Media B > Media C and plant top growth was greater in coir- than in peat-based media. Differences in growth could be due, in part, to differences in media water-holding capacities.

The objective of this study was to determine which combination of three types of irrigation systems, three fertilization method, and four growing media produced optimum growth of flowering vinca, Catharanthus roseus. Irrigation systems used included ebb-and-fl ood, drip, and pulse; fertilization methods included slow release, prepackaged, and custom mixed; and the four growing media were peatmoss:perlite:vermiculite (1:1:1, by volume), peatmoss:rockwool (1:1, by volume), and 0.6-cm diameter shredded rubber or fabric from waste tires: vermiculite:peatmoss (1:1:2, by volume). Four replications of five plants each were used in each of the 36 treatment combinations. Plants were potted 29 and 30 May 1996 in 10-cm containers, grown for 10 weeks, and harvested 6 Aug. 1996. The drip-irrigated benches were irrigated once per day for 15 s. Pulse-irrigated benches were watered twice per day for 6 s. This resulted in the drip- and pulse-irrigated plants receiving a similar volume of water daily. Ebb-and-fl ood benches were filled once per day with drainage occurring 15 min after filling. Ending plant heights and dry weights indicated that those plants in the prepackaged fertilizer/drip or ebb-and-fl ood irrigation/shredded tire fiber growing medium were comparable to plants grown in the peatmoss:rockwool medium with the same fertilizer and irrigation methods.

The gut capacity of shrimp larvae is minimal, and their digestion is often challenged by the inevitable fact that they tend to develop slowly during the zoea stage. Many studies approved that the digestive capacity of shrimp larvae could be improved by increasing the retention time of food in the intestine. Gut evacuation time and fullness of the gut are crucial parameters in assessing the growth of shrimp larvae, and the diet as well as  environmental conditions indeed influence the activity of these parameters. Although many species of shrimps have a wide salinity tolerance, more specific research on salinity and its relation to the type of diet is necessary to find the optimum condition supporting the growth of shrimp larvae. By employing Penaeus merguiensis larvae, this study evaluates the effect of three nominal salinities (28, 32, and 36 ppt) and types of diets (Diet A: 100% live feed; Diet B: 100% FRIPPAK; Diet C: a combination of Diet A and Diet C, 50 % each) toward the fullness of gut and gut evacuation time of the newly introduced Penaeus merguiensis larvae culture. The result showed that the longest gut evacuation time and the highest percentage of gut's fullness were found in all Zoea reared with Diet A at salinity 28 and 32 ppt; Zoea-1 at 28 ppt with Diet A; Zoea-2 at 32 ppt with Diet A; Zoea-3 at 32 ppt with Diet A. Longer gut evacuation time would have an impact on the higher percentage of the fullness of gut. The higher fullness of the gut also indicates that the larvae have the best capacity to produce energy and achieve optimum growth.

This experimental study determined the weight of wire used in power supply using the laboratory technique and procedure to gather data. There were two designs with three treatments each, prepared and subjected to using the Two Way Analysis of Variance. The treatments for the first design were: one is 1 1/8 inch by 1 1/8 inch area and output voltage of 6 volts; two is 1 1/8 inch by 1 1/8 inch area and output voltage of 36 volts; three is 1 1/8 inch by 1 1/8 inch area and output voltage of 110 volts. The treatments for design number two were: one is 1/2 inch by 1/2 inch area and output voltage of 12 volts; two is 3/4 inch by 3/4 inch area and output voltage of 12 volts; three is 1 inch by 1 inch area and output voltage of 12 volts. The test result of significant differences in the effectiveness, efficiency and performance of the different treatments showed no significant difference on windings, temperature, voltage, size of the iron core, current, power, number of turns, turns per volt and force applied in winding.

Fourteen children who misarticulated some phones of the /s/ phoneme were tape recorded articulating several lists of items involving /s/. The lists included the Mc-Donald Deep Test for /s/, three lists similar to McDonald’s but altered in broad context, and an /s/ sound production task. Scores from lists were correlated, compared for differences in means, or both. Item sets determined by immediate context were also compared for differences between means. All lists were found to be significantly correlated. The comparison of means indicated that both broad and immediate context were related to test result. The estimated “omega square” statistic was used to evaluate the percentage of test score variance attributable to context.
