Creative Industries and Regional Productivity Growth in the Developing Economy: Evidence from Indonesia

This paper examines the degree to which creative industries stimulate regional productivity growth in a developing country, Indonesia. The Indonesian government promotes long‐established “traditional” craft businesses as creative industries, but they pay less attention to new knowledge creation and focus on highlighting heritage values as selling points. Our findings show that the “real” creative industries are still scarce and found mostly in fairly advanced urban regions. These industries are more likely to be an indicator than a driver of regional economic development. Meanwhile, those traditional businesses are much larger than creative industries and potentially contribute to regional productivity through consumption activities, thereby requiring different policy strategies.     

Preliminary Study of Variable Rate Application – Organic Liquid Fertilizer by Using SPAD Chlorophyll Meter on System of Rice Intensification (SRI) Cultivation

Knowing actual nutrient requirements for rice plants is crucial in supplying the correct amount of fertilizer, especially nitrogen since nitrogen is one of the most key limiting nutrients in rice cultivation. A preliminary study of variable rate application (VRA) on System of Rice Intensification (SRI) planting by using organic foliar fertilizer was carried out to determine the effectiveness of precision fertilization. Foliar fertilizer was formulated based on actual nitrogen needed by rice plants using Soil-Plant Analyses Development (SPAD) chlorophyll meter measurements. The experiment was laid out in a randomized complete block design (RCBD) with four treatments (50% fixed rate, 100% fixed rate, 150% fixed rate and VRA) and four replications for each treatment. Plant growth performances (plant heights, number of tillers, number of panicle and flower) and yield performances (grain yield, number of grain, 1000-grain weight and number of spikelets) were recorded during the study. The results showed that foliar application of VRA resulted in significantly higher yield performances; grain yield (13.65 g), number of grain (807.50), 1000-grain weight (16.79 g), and number of spikelets (7.50) compared to uniform fertilizer applications. VRA treatments had the highest SPAD readings at every planting stage during the experiment; however, a high nitrogen supply was needed during the mid-tillering stages (35 DAT) compared to other fertilizer rates. Besides, VRA application shows the most savings in term of total nitrogen supply (415 µg) compared to uniform rates application; 50% fixed rate (400 µg), 100% fixed rate (810 µg), and 150% fixed rate (1210 µg).     

Business networks,social capital and the economic performance of creative and cultural industries: The case of Indonesia

This study examines the ways in which networking characteristics and practices influence the economic performance of creative and cultural industries. The notion of social capital is used to conceptualise the complex nature of networks, including both professional and social relationships that occur on multiple levels. This qualitative study is set in the context of Indonesia, in which two cases are examined: creative apparel entrepreneurs in Bandung and batik producers in Surakarta. The results show that regional environments provide opportunities for creative industries to find specialist suppliers, to gather market information and, importantly, to find and cross‐fertilise new ideas. Although regions provide these opportunities, the firms’ internal social capital is crucial in being able to internalise and transform the knowledge from the environment into innovative values embodied in their products.     

Phenotypic and molecular characterization of Yersinia ruckeri isolates from rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) in Turkey

The aim of the study was the phenotypic and molecular characterization of Yersinia (Y) ruckeri strains, the causative agent of Enteric Redmouth Disease (ERM), by antibiotyping, random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) and sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns of whole cell proteins. For this aim, a total of 97 Y ruckeri isolates were analyzed. The isolates were distinguished into ten antibiotypes and six phenotypes according to their resistance properties and whole cell protein profiles, respectively. Also, a glycoprotein band of approximately 25.5 kDa was observed in all Y ruckeri strains tested. In all strains, six different RAPD types were observed. In conclusion, Y ruckeri strains isolated from rainbow trout of fish farms in Turkey showed variation according to their phenotypic and genotypic characteristics, and the use of these three typing techniques in double and triple combinations could be more useful for discriminating the strains.     

A new genus and two new,rare freshwater mussel (Bivalvia: Unionidae) species endemic to Borneo are threatened by ongoing habitat destruction

1. Most of the Bornean endemic freshwater mussel (Unionida) species known to date have not been recorded by science for the past 50 years or more, owing to a lack of research effort and presumed population losses.
2. This study assessed current patterns and recent changes in the diversity and distribution of freshwater mussels in north-eastern Borneo. Physical surveys and interviews were conducted at 24 sites, and anecdotal evidence for current or historical presence of mussels was collected for a further 13 sites.
3. Native species, i.e. Schepmania sp. and Khairuloconcha sahanae gen. & sp. nov., were only found in one small stream of the Kinabatangan River basin within the Gomantong Forest Reserve, whereas the non-native Sinanodonta cf. woodiana was common across the study area.
4. Molecular phylogenetics (five genes) of the native taxa, including comparative material from West Kalimantan and Sarawak, revealed: (i) the presence of a new genus with two new, rare species: Khairuloconcha lunbawangorum sp. nov. in the Limbang River basin and K. sahanae in the Kinabatangan River basin; (ii) that Khairuloconcha and Ctenodesma form the Bornean endemic tribe Ctenodesmini trib. nov.; and (iii) that Schepmania represents another Bornean endemic tribe Schepmaniini trib. nov.
5. Both Khairuloconcha gen. nov. species are known from a single stream each and are apparently restricted to forest stream habitats where they occur at very low densities. Schepmania appears to have a severely contracted range in the Kinabatangan and adjacent basins. We urgently call for full protection of the currently known sites of K. lunbawangorum and K. sahanae, and development of an action plan to save the Bornean freshwater mussel fauna.

Levels of fire blight (<Emphasis Type="Italic">Erwinia amylovora</Emphasis>) susceptibility of native apple,pear and quince germplasm from Lake Van Basin,Turkey

Fire blight resistance of apple, pear and quince genetic resources from Lake Van Basin (eastern Turkey) was tested using Erwinia amylovora strain Ea Van. Shoot tips of 92 native accessions (48 accessions for apple, 38 accessions for pear and 6 accessions for quince) were wounded for inoculation, and artificially inoculated with pathogenic bacteria under greenhouse conditions. The levels of resistance of accessions were classified in comparison with control varieties according to the genotype susceptibility index (GSI%) scores based on the lesion length on shoots of each genotype. Fire blight resistance of accessions consisted of five classes: resistant (R), moderately resistant (MR), moderately susceptible (MS), susceptible (S) and highly susceptible (HS). GSI% scores differed significantly among accessions from each fruit species (p < 0.01). GSI values ranged from 12.4% to 64.1% for apple genotypes, from 17.2% to 55.1% for pear genotypes, and from 17.8% to 43.4% for quince genotypes. No resistant genotypes of apple, pear and quince were observed. Seven accessions of apple, two accessions of pear and one accession of quince were MR. 25 accessions of apple, 14 accessions of pear and one accession of quince were MS. These findings indicate a considerable variation in fire blight resistance and could contribute to breeding efforts regarding fire blight resistance in apple, pear and quince.     

Fire blight (Erwinia amylovora) resistant/susceptibility of native apple germplasm from eastern Turkey

This study aimed to determine the resistance/susceptibility to fire blight of apple germplasm resources from the province of Erzincan in eastern Turkey. In total, 32 native apple accessions from four regions within the province were tested under greenhouse conditions by inoculating the shoot tips with pathogenic bacterium. Shoot tips were wounded for inoculation. Genotypical susceptibility index (GSI%) values were computed for each genotype based on the length of the lesion that developed on each shoot. Accessions were grouped into five classes of resistance/susceptibility, as follows: Class A (resistant); Class B (moderately resistant); Class C (moderately susceptible); Class D (susceptible); and Class E (highly susceptible). GSI% values differed significantly among accessions (p < 0.01). Five accessions received a rating of Class A, and 7 accessions received a rating of Class B. This was followed by 9 accessions with a rating of Class C, 5 accessions with a rating of Class D and 6 accessions with a rating of Class E. The findings of this study are expected to contribute to breeding efforts with respect to apple resistance to fire blight.     

Disease of rainbow trout caused by Pseudomonas luteola

Bacteria isolated from rainbow trout, Oncorhynchus mykiss, kept in a farm, in Turkey. During the outbreak, 40% of the rainbow trout (10-40 g) died. Typical clinical signs were exophthalmia, dark pigmentation, hemorrhage at the base of the pectoral, pelvic, anal fins and around the vent. Internal signs were enlarged spleen, pale liver and intestine filled with yellowish fluid. Liver, kidney and spleen of diseased fish, were aseptically streaked on Tryptic Soy Agar. After incubation, pure cultured colonies were observed and biochemically characterized with API 20 NE and other biochemical tests. Cultured bacterial 16 S rDNA gene was sequenced. Based on biochemical characteristics and sequence of 16 S rRNA, the causative bacteria were identified as Pseudomonas luteola. This study reports the first P. luteola infection in fish.
