Analisis Perdagangan Kopi Indonesia di Pasar Internasional

Indonesia merupakan salah satu negara produsen dan eksportir kopi terbesar di dunia. Akan tetapi, pertumbuhan volume ekspor kopi di Indonesia lebih rendah dari pertumbuhan produksinya. Rendahnya ekspor kopi Indonesia disebabkan oleh banyak faktor yang mempengaruhi perdagangan kopi Indonesia di pasar Internasional. Tujuan dari penelitian ini adalah menganalisis faktor-faktor yang mempengaruhi perdagangan kopi Indonesia di pasar Internasional dan menerangkan potensi perdagangan kopi Indonesia di negara tujuan. Metode analisis yang digunakan adalah analisis data panel dengan gravity model dan analisis potensi perdagangan. Hasil penelitian menunjukkan bahwa peubah yang berpengaruh signifikan terhadap ekspor kopi Indonesia adalah GDP riil/kapita Indonesia, GDP riil/kapita negara tujuan, jarak ekonomi antara Indonesia dengan negara tujuan, dan keanggotaan WTO. Sementara itu, Indonesia memiliki potensi untuk melakukan ekspansi perdagangan kopi ke negara-negara tujuan di masa yang akan datang karena perdagangan kopi Indonesia di negara tujuan masih under trade. Implikasi kebijakan adalah Indonesia harus meningkatkan pangsa pasar dengan memprioritaskan untuk mengekspor kopi ke Mesir dan Aljazair karena kedua negara tersebut memiliki pertumbuhan GDP riil/kapita yang tinggi dan perdagangan kopi Indonesia di Mesir dan Aljazair masih under trade.Kata Kunci: Kopi, ekspor, gravity modelIndonesia is one of the largest coffee producer and exporter in the world. However, the growth of Indonesia\u27s coffee export volume is lower than that of its production. Indonesia\u27s coffee export is low due to many factors affecting the Indonesia\u27s coffee trade in International market. The purposes of this study are to explain the factors that influence Indonesia\u27s coffee trade in International market and the trade potential of Indonesian coffee in destination countries. The analysis methods used are analysis of panel data with gravity model and trade potential analysis. The results showed that variables that significantly influence Indonesia\u27s coffee exports are real GDP/capita of Indonesia, real GDP/capita of destination countries, economic distance between Indonesia and destination countries, and WTO membership. Meanwhile, Indonesia has potency to expand coffee trade to the destination countries in the future. Therefore, Indonesia should increase the market share by prioritizing of exported coffee to Egypt and Algeria having high in real GDP/capita growth rate

Mean body sizes of amphibian species are poorly predicted by climate

Aim Climate is thought to exert a strong influence on animal body sizes. We examined the relationship between amphibian body size and several climatic variables to discern which climatic variables, if any, affect amphibian size evolution. Location Europe and North America. Methods We assembled a dataset of mean sizes of 356 (out of 360) amphibian species in Europe, the USA and Canada, and tested how they are related to temperature, precipitation, primary productivity and seasonality. First, we examined the body size distributions of all the species inhabiting equal‐area grid cells (of 96.3 km × 96.3 km) using randomizations to account for the effects of species richness. Second, we examined the relationship between mean species body size and the environmental predictors across their ranges accounting for phylogenetic effects. Results The observed amphibian body size distributions were mostly statistically indistinguishable from distributions generated by random assignment of species to cells. Median sizes in grid cells were negatively correlated with temperature in anurans and positively in urodeles. The phylogenetic analysis revealed opposite trends in relation to temperature. In both clades most climatic variables were not associated with size and the few significant relationships were very weak. Main conclusions Spatial patterns in amphibian body size probably reflect diversity gradients, and relationships with climate could result from spurious effects of richness patterns. The large explanatory power of richness in the grid‐cell analysis, and the small explanatory power of climate in the interspecific analysis, signify that climate per se has little effect on amphibian body sizes

Elevation is a stronger predictor of morphological trait divergence than competition in a radiation of tropical lizards

1. Adaptations for efficient performance are expected to shape animal morphology based on selection for microhabitat use and ecological forces. The presence of competitor species is predicted to cause niches to contract and enhance trait divergence. Therefore, increased species richness is expected to lead to greater trait divergence, and to result in reduced overlap and similarity between morphologies of sympatric species. 2. We examined patterns of morphospace occupancy and partitioning in the skink fauna of New Guinea, the world's largest tropical island. Because skink species richness is largely decoupled from elevation in New Guinea, we could examine the effects of both factors (as proxies for competition and abiotic conditions), on morphospace occupancy and partitioning. 3. We measured 1,860 specimens from 79 species of skinks throughout Papua New Guinea, and examined their morphospace occupancy in a spatial context. We calculated, for each assemblage within equal‐area cells, the volume of morphospace occupied by all skinks, the mean volume occupied per species, and the mean distance and overlap between all species pairs. We then examined whether these metrics are related to species richness and elevation. 4. Elevation is a stronger predictor of morphospace occupancy than species richness. As elevation increases, intraspecific variation decreases and morphologies become more similar to each other such that overall morphospace occupancy decreases. Highland skinks are, on average, smaller, thinner and shorter limbed than lowland species. 5. We hypothesise that harsh climates in the New Guinea highland habitats impose strong selection on skinks to occupy specific areas of morphospace that facilitate efficient thermoregulation in suboptimal thermal conditions. We conclude that the effect of competition on trait divergence on a community and assemblage scale is eclipsed by abiotic selection pressures in these harsh environments

Analysis of the distribution and structure of integrated banana streak virus DNA in a range of Musa cultivars

The cDNA encoding the glycoprotein α (GPα) subunit of tilapia (Oreochromis mossambicus) was partially cloned using RACE-polymerase chain reaction (PCR) technique. The amplified cDNA was found to be 583 bases long, and to consist of a portion of the signal peptide, the full sequence encoding the mature peptide (94 amino acids) and the 3′ untranslated region. Northern blot analysis revealed a single band of approximately 600 bp. Alignment of the deduced amino acids of the mature protein showed that the tilapia GPα subunit shares more than 80% identity with that of other perciform fish (i.e. striped bass, sea bream and yellowfin porgy) and less than 70% with that of more taxonomically remote fish and other vertebrates. Exposure of dispersed tilapia pituitary cells to salmon gonadotropin-releasing hormone (sGnRH) elevated GPα mRNA levels via both PKC and cAMP-protein kinase A (PKA) pathways. The transcript levels were also regulated by pituitary adenylate cyclase activating polypeptide (PACAP) and neuropeptide Y (NPY), both acting through PKC and PKA pathways. Moreover, a combined treatment of PACAP or NPY with GnRH seems to have an additive effect on the GPα subunit gene transcription. These results suggest that in tilapia the expression of GPα subunit is regulated by GnRH mainly via PKC and PKA pathways. Furthermore, PACAP and NPY can elevate the GnRH-stimulated GPα subunit transcription and can directly affect the subunit mRNA levels, via the same transduction pathways

Hypoglycemia After Administration of Somatostatin Analog (SMS 201-995) in Metastatic Carcinoid

SMS 201-995 (Sandoz Pharmaceuticals. East Hanover NJ) is a synthetic peptide analog of native somatostatin that has been used to relieve .symptoms caused by neuroendocrine tumors. Reports have described an insulin suppressive effect of SMS 201-995 that results in elevations of blood glucose. We report a patient with a metastatic small bowel carcinoid and renal failure in whom mild symptomatic hypoglycemia occurred 30 to 60 minutes after SMS 201-995 administration. No increase in insulin or decreases in glucagon. Cortisol, or catecholamines were observed during these hypoglycemic episodes. Elevated levels of growth hormone fell gradually following SMS 201-995 administration and did not temporally correspond to the 30- to 60-minute nadir of blood glucose. However SMS 201-995 levels peaked during this 30- to 60-minute period. As clinical experience with this drug broadens, patients whose glucose control is dependent on counter-regulatory hormones should be monitored for the possibility of hypoglycemia

Minimal cold knife conization height for high-grade cervical squamous intraepithelial lesion treatment

AbstractObjectivesTo assess the relationship between cold-knife conization specimen height, cervical intraepithelial neoplasia (CIN II/III) size and endocervical margin involvement by CIN II/II.Study designA cross-sectional study was performed. Cold knife cone specimens with a diagnosis of CIN II/III were selected. Epidemiological data and pathology reports were obtained through a chart review. All samples from each cone specimen showing CIN II/III and the squamocolumnar junction were selected. Cone height (mean±standard deviation), intraepithelial lesion size, and size of endocervical surgical margins were measured.ResultsFour hundred and forty-seven samples were analyzed from 97 cone specimens. Section size ranged from 3.4 to 29.7mm, tumor size from 0.3 to 17.5mm, and tumor distance from the endocervical margin, from 0.0 to 22.0mm. Age and parity were similar in the positive vs. negative margin groups (37.6±10.0 years vs. 37.7±11.9 years respectively, p=0.952, and 2.2±1.7 births vs. 2.6±1.9 births respectively, p=0.804), whereas cone height (22.4±6.9mm vs. 17.1±5.6mm, p=0.013) and tumor size (6.12±3.25mm vs. 10.6±4.45mm, p<0.001) were significantly different in negative vs. positive margin groups respectively.ConclusionsUse of cone height to identify the likelihood of negative margins enables better estimation of the risk–benefit ratio of greater risks of bleeding, stenosis, and obstetric complications (cervical incompetence) versus greater risks of residual and recurrent disease

Gecko diversity : a history of global discovery

1935 gecko species (and 224 subspecies) were known in December 2019 in seven families and 124 genera. These nearly 2000 species were described by ~950 individuals of whom more than 100 described more than 10 gecko species each. Most gecko species were discovered during the past 40 years. The primary type specimens of all currently recognized geckos (including subspecies) are distributed over 161 collections worldwide, with 20 collections having about two thirds of all primary types. The primary type specimens of about 40 gecko taxa have been lost or unknown. The phylogeny of geckos is well studied, with DNA sequences being available for ~76% of all geckos (compared to ~63% in other reptiles) and morphological characters now being collected in databases. Geographically, geckos occur on five continents and many islands but are most species-rich in Australasia (which also houses the greatest diversity of family-level taxa), Southeast Asia, Africa, Madagascar, and the West Indies. Among countries, Australia has the highest number of geckos (241 species), with India, Madagascar, and Malaysia being the only other countries with more than 100 described species each. As expected, when correcting for land area, countries outside the tropics have fewer geckos
