Abstract

Two approachment to increase yield productivity with new variety throught new plant type (NPT) concept and heterosis exploitation of hybrid rice. The research was to evaluated yield and yield component of 36 hybrid rice genotypes in preliminary yield trial at two locations. The experiment was conducted in the second season MT (II) 2013 at the Sukamandi experimentalstation, Subang, West JavaProvince and in Batang, Central Java Province by usingRandomized Complete Block Design (RCBD). The material used were36hybrid rice genotypes and four check varieties namely Hipa8, Hipa Jatim2,Ciherang, and Longping Optima. The results showed that grain yield had been effected by location, genotypes, and both interactions. There were two hybrid rice genotypes that give high yield potential than four check varieties, and one hybrid rice genotype significantly different from Longping Optima. Those hybrids were GMJ6/CRS519 (9.9 t/ha) and GMJ14/CRS757 (9.5 t/ha), and A1/CRS518 (6.2 t/ha). Based on path analysisnumber of productive tiller and number of total grain per panicle have direct effect to yield with path coefficient as 0.4028 and 0.2153. Length panicle and seed set also gave positif and significant direct effect to yield as 0.095 and 0.0956, so these characteristics could be used as selection criteria.

Abstract

Corm of iles-iles (Amorphophallus muelleri Blume) is extracted for glucomannan production, a material that is widely used in medicinal, food, and beverage industries. Increasing demand on glucomannan promotes fast expansion of planting area in Indonesia, however, seed availability is limited. The objective of the experiment was to study corm age, planting distance, and planting depth in order to enhance seed production in A. muelleri. Two experiments were conducted under paranet of 65% in Leuwikopo Experimental Farm, Bogor Agricultural University (IPB) from June-November 2015. First experiment used 0- (bulbils), 1-, 2-, 3-, and 4-year-old corms. Second experiment used flowering 3-year-old corms, arranged by factorial of planting distance (0 × 0 cm and 50 × 50 cm) and planting depth (0 and 5 cm in depth). Results showed that flowering of A. muelleri was dependent on corm age, 96% of 3-year-old corms produced flower but none of the 1- and 4-years-old corms produced flower, whereas 8% of 2-year-old corms produced flower. Planting distance did not affect flower growth, while planting at a depth of 5 cm enhanced seed production. Present experiments imply that application of large 3-year-old corms, planting in dense population and at depth of 5 cm could enhance seed production of A. muelleri. It needs further investigation on seed quality from flowering of present treatments.

Abstract

East Halmahera District is one of the mining central areas Nickel in North Moluccas. This mining had a great impact on water quality changes. The aims of this study were to determine the content of Suspended Particulate Matter in East Halmahera waters, determine the water quality level, and determine fishing ground degradation level. The results showed the suspended solids in East Halmahera waters were above NAB, which had been set by Ministry of Environment those were less than 25 mg/l. While the average of SPM content in East Halmahera waters were above 25 mg/l except Wasile. The content of nickel in waters were known under NAB, but it had approached the NAB value which it means nickel had impacted the waters. Water quality changes had given impact to the fish degradation in waters, which the fish were captured by lift netwere classified in ilegal size (IS), that Stolephorus spp 62%, Loligo spp 67%. The number of IS for anchovy and squid were caused by lift net operation which were located near the coastal area where this area has been pressed by mining activities. This condition did not happen on purse seine and gillnet which legal size (LS) of Decaptrus spp 96% and Rastrilliger spp 90%. It was caused by fishing gear which operated far from coastal area. Based on the analysis, can be concluded that the mines Ni has a considerable effect on the degradation of water quality and reduction in size of a decent fish caught mainly lift nets.
