Thermal comfort study of plastics manufacturing industry in converting process. Thermal comfort is one of ergonomics factors that can create a significant impact to workers performance. For a better thermal comfort, several environment factors (air temperature, wind speed and relative humidity) should be considered in this research. The object of the study is a building for converting process of plastics manufacturing industry located in Malang, Indonesia. The maximum air temperature inside the building can reach as high as 36°C. The result of this study shows that heat stress is dominantly caused by heat source from machine and wall building. The computational fluid dynamics (CFD) simulation is used to show the air characteristic through inside the building. By using the CFD simulation, some scenarios of solution are successfully presented. Employees thermal comfort was investigated based on predicted mean vote model (PMV) and predicted percentage of dissatisfied model (PPD). Existing condition gives PMV in range from 1.83 to 2.82 and PPD in range from 68.9 to 98%. Meanwhile, modification of ventilation and replacing ceiling material from clear glass into reflective clear glass gave significant impact to reduce PMV into range from 1.63 to 2.18 and PPD into range from 58.2 to 84.2%. In sort, new design converting building process has more comfortable for workers.
Subject and purpose of work: Community Empowerment in Sustainable Agricultural Development and CSR (Study of spice farmers in Maluku Utara). One of the duties of the nation is to facilitate prosperity for its citizens through development. Such development is pursued by the government to reach economic growth by utilizing all agriculture potentials and by organizing community development. Materials and methods: In this study, the goals are to identify, describe and analyze the empowerment of the spice farmers’ community in Maluku Utara in sustainable agricultural development and CSR. This study is descriptive in nature and uses the qualitative approach, while data analysis relies on the Creswell’s model. Maluku Utara has a resource potential that is needed for sustainable agriculture development and CSR for community welfare. Results: Through empowerment, which involves several stages, such as enlightenment, capacity building, and enforcement, it is possible to improve awareness, capacity, skill and strength of the community to exploit all potentials. The support given to the spice farmers’ community in sustainable agriculture development and CSR is not at the maximum. Despite this support, there are factors constraining community empowerment in sustainable agriculture development and CSR. Conclusions: These constraints may come from community, a very low number of agriculture counselors, natural resource inadequacy, and also weather factors at Maluku Utara, all of which hamper the empowerment process.
A total of 26 isolates of Fusarium proliferatum and F. sacchari were isolated from rice in the Peninsular Malaysia and Kalimantan, Indonesia. Spontaneous chlorate-resistant sectors (CRSs) were recovered from all wild type of both Fusarium species when cultured on two chlorate media. The non-utilizing (nit) mutants were generated as crn (chlorate resistant, nitrate utilizing), nit1, nit3 and nitM based on phenotyping growth-types on diagnostic media with different sources of nitrogen. The nit mutants were paired on minimal medium (MM) for examining the vegetative compatibility. The majority of nit mutants (32.3-46.5%) recovered were nit1. Eight and seven vegetative compatibility groups (VCGs) of F. proliferatum and F. sacchari were identified, respectively. The isolates of F. proliferatum and F. sacchari were genetically diverse as shown by the number and distribution of the VCGs. No strong correlation was observed between VCGs of both species and location.
The impacts of the 26th December 2004 Indian Ocean tsunami were examined on three separate coastal sectors in the west, north and east of Banda Aceh. The most vulnerable coasts are the soft coasts, such as mangroves, and the least vulnerable are the rocky headlands with the sandy coasts occupying a broad intermediate position. The extent of impact for each category of coasts appears to vary with the tsunami wave height and other characteristics. Coastal recovery was remarkably rapid, especially for sandy beaches. In some cases, foredunes returned to the coast. The impacts and recovery processes provide valuable lessons for coastal management, for example, in the replanting of mangroves and other coastal vegetation in the modified coastal environments and the questionable construction of seawalls on accreting coasts. In years to come, the tsunami impacts would disappear, except for modifications by human activities.
The tortricid fauna of Seram is comprised of 35 genera and 60 species. Two genera (Kanikehia gen. n., Mersa gen. n.) and 41 species (Reptilisocia gunungana sp. n., Schoenotenes peos sp. n., Schoenotenes emmetra sp. n., Schoenotenes elasma sp. n., Metachorista longiseta sp. n., Cornuticlava binaiae sp. n., Cornuticlava kobipoto sp. n., Mimeoclysia mystrion sp. n., Kanikehia kanikehiana sp. n., Mersa metochia sp. n., Homona obtusuncus sp. n., Homona privigena sp. n., Isodemis solea sp. n., Isodemis phloiosignum sp. n., Isotenes syndesma sp. n., Isotenes latitata sp. n., Zacorisca leura sp. n., Zacorisca helicocestum sp. n., Zacorisca seramica sp. n., Zacorisca digna sp. n., Adoxophyes planes sp. n., Adoxophyes meion sp. n., Adoxophyes olethra sp. n., Adoxophyes lacertana sp. n., Adoxophyes panurga sp. n., Adoxophyes luctuosa sp. n., Demeijerella palleophyton sp. n., Lobesia drasteria sp. n., Rhectogonia sandrae sp. n., Metrioglypha ithuncus sp. n., Aterpia monada sp. n., Asaphistis omora sp. n., Rhodacra leptalea sp. n., Rhopobota jonesiana sp. n., Rhopobota nasea sp. n., Rhopobota grisona sp. n., Peridaedala speculata sp. n., Peridaedala stenygra sp. n., Fibuloides rusticola sp. n., Spilonota terenia sp. n., Cryptophlebia heterospina sp. n.) are described as new. Rhapsodica MEYRICK, 1927 is synonymized with Homona WALKER, 1863, and Rhapsodica antitona MEYRICK, 1927 is transferred to Homona WALKER, 1863. Biological data are included with each particular species.
