No full textThe purpose of this research is to study the response of benthic insect community in the headwater of BoyongRiver, Mount Merapi, four months post-forest fire in 2002. Energy at the headwater ecosystem was based on thedetritus food-chain. The presence of benthic community indicated forest health. The forest fire caused energy whichentered into the river changed from allochtonous coarse particulat organic matter (CPOM) to fine particulatorganic matter (FPOM). This change would be responded by the functional group of benthic community. Datawere collected with Surber Sampler. The result showed that there were 12 genus constituent of benthic insectsconsisted of functional groups of collector gather, collector filter, predator, dan scrapper. The dominant functionalgroups were collector gather and collector filters, 2256 individual/m3 or 86.02% and the dominant genus of Baetisand Leutcra. Otherwise, scrapper was founded 111 individual/m3 or 4% and predator 256 individual/m3 or 10%.This condition showed that four months post-forest fire indicated dominant allochtonous in Boyong River wasCPOM and FPOM with size of 1 mm. The quality of nutrients in the water was low, otherwise, the sedimentnutrients was high. The dominance of functional group of collectors indicated that ecosystem of headwater forestin Boyong River had not been fully recovered

MODEL KESUKSESAN PRODUK SANITER
No full textA company that manufactures home decorations and sanitary products has not been able to achieve the expectedproduction utility. This was indicated by the installed production capacity (of the sink) in 2013, which has not beencompletely consumed. Therefore, studies that explore customer needs and their corresponding levels of customersatisfaction need to be done. Achieving the desired product quality and customer satisfaction can be an entrancefor achieving higher sales. This study was conducted in several stages, with the sink selected as the type of productfor the research object. First, the quality attributes of the sink were identified. Second, the importance levels ofthe quality attributes were searched by questionnaires. Third, the sink quality attributes were grouped into theclassification of quality attributes by the Kano model. This study gave some results. First, 90% of the averageimportance level of the sink quality attributes were between ‘important’ and ‘extremely important’. Second, thesurvey that used the Kano model indicated that (1) ‘performance’ was a must-be quality attribute, (2) ‘aesthetics’was not an indifferent quality attribute from ‘attractiveness’, except for ‘excellence drainage’, which was classifiedinto a must-be quality attribute, (3) features could improve customer satisfaction quickly through ‘the sink priceis competitive’, (4) the ‘durable sink color’ and ‘scratch resistant’ attributes can increase customer satisfaction, (5)‘materials that are for maintenance are included when buying the sink’ could increase consumer satisfaction veryquickly, and (6) the higher the reputation of the company, the higher the customer satisfactio
SIMULASI ALIRAN PASIEN RAWAT INAP UNTUK MENGURANGI BOTTLENECK
No full textBottleneck is possible to occur in a system like hospital, especially in admission and discharge of inpatientprocesses. It can have impact on increasing waiting time and delayed time. Some alternatives were proposed toreduce them, i.e. shift scheduling and human resource allocation. This research modelled real system accompaniedby two scenarios: the first scenario was conducted by balancing human resource utility without altering numberof employees, whereas the second scenario considered possibility of changing number of employees. The resultsshowed that both scenarios produced reduction of waiting time and delayed time. The first scenario is more feasiblecompared to the second as no hiring or firing employees occurred, resulting in waiting time reduction of 110.6minutes (15%) and decrease in delayed time by 184 minutes (15.9%). The reduction of waiting time and delayedtime is higher in scenario 2, which are 423.6 minutes (57%) and 281 minutes (24%), respectively. However, theremust be 4 additional employees hired in pharmacy applied in scenario 2
PENENTUAN BOBOT KEPENTINGAN DECISION MAKER DALAM GROUP DECISION MAKING
No full textGenerally, there are two criteria which are widely used to determineDM’s weight of interest, i.e. competenceand consensus. Various studies related to determine DM’s weight of interest based on competence or consensusseparately have been conducted. Each criterion has its own advantages. The advantage of using competence as acriterion is DMs who have high competence based on their consistence on the decisions made will have high of interest weight. Meanwhile, consensus criterion emphasizes a DM/s contribution to a group without consideringthe DM’s ability or competence.Considering the advantages of both criteria, this study developed a model to determine DM’s weight of interestby considering the DM’ competence and consensus in a GDM. This study used2 group decision making cases totaling in 6 groups consisting of 5 people each. Collected data was then processedusing DM’s weight of interest determination method based on competence and consensus. A model was thendesigned using regression method and fuzzy method. Therefore, a model to determine DM’s weight of interest was obtained by considering competence and consensus. DM’s weight of interest from each method was then involvedin group decision making. The research result showed that group decisions made by involving DM’s weight of interest were better decisions. It implies competence and consensus are two criteria which can be used to determineDM’s weight of interest
