Struktur Dan Integrasi Pasar Kopi Arabika Gayo Di Kabupaten Aceh Tengah Dan Bener Meriah
Kopi Arabika Gayo merupakan komoditas utama di Kabupaten Aceh Tengah dan Bener Meriah. Sebagian besar (86%) produksi kopi diekspor ke pasar dunia. Selama tahun 2006-2012, pergerakan harga kopi di tingkat eksportir mengalami kenaikan sebesar 17,18%, namun di tingkat petani mengalami penurunan sebesar 1,73%. Penelitian ini bertujuan menganalisis struktur dan integrasi pasar kopi Arabika Gayo. Data yang digunakan merupakan data time series harga bulanan kopi selama tahun 2008-2012. Analisis struktur pasar ditentukan melalui rasio konsentrasi empat Perusahaan terbesar (CR4) dan hambatan masuk pasar melalui nilai skala efisiensi minimum (Minimum Efficiency Scale/MES). Analisis integrasi pasar menggunakan model yang telah dikembangkan oleh Ravallion (1986). Hasil penelitian menunjukkan bahwa konsentrasi rasio empat Perusahaan terbesar (CR4) di tingkat eksportir sebesar 71,12% dan terdapat hambatan masuk pasar yang ditunjukkan dengan nilai MES sebesar 28,53%. Karakteristik struktur pasar menunjukkan bahwa pasar terkonsentrasi dengan tingkat persaingan yang kecil. Struktur pasar yang terbentuk mengarah pada struktur pasar oligopsonistik dan terdapat lembaga pemasaran yang dominan dalam proses penentuan harga yaitu eksportir. Selain itu, analisis integrasi pasar menunjukkan bahwa pasar kopi di tingkat petani tidak terintegrasi dengan eksportir baik dalam jangka panjang maupun jangka pendek. Hal ini menunjukkan bahwa dalam proses penentuan harga petani cenderung sebagai penerima harga.Kata Kunci: Kopi Arabika Gayo, struktur pasar, integrasi pasar, harga, oligopsonistikArabica Gayo Coffee is the main commodity of Central Aceh and Bener Meriah regencies. Almost 86 percents of coffee bean produced from those areas is exported to the world market. Though the coffee price increased 17.18 percent at the exporter level during 2006 to 2012, but at the farm level the price of coffee decreased 1.73 percent. The purpose of this study was to analyze the structure and integration market of Arabica Gayo coffee. The data used was monthly time series of prices during 2008 to 2012. The analysis of market structure is determined by the concentration ratio of four large firms (CR4) and barriers to market entry through the Minimum Efficiency Scale (MES) value. The analysis of market integration used models that have been developed by Ravallion (1986). Research results showed that the market concentration ratio (CR4) at the exporter level was 71.12 percents and there were barriers to enter the Arabica Gayo coffee market with MES of 28.53 percents. These structural characteristics indicated that market structure is concentrated with a small level of competition. The market structure is oligopsonistic and there is a single marketing institution which determine the Arabica Gayo coffee price. This single institution is exporter. In addition, analysis of market integration showed that the coffee market at the farm level was not integrated with the exporter level in the long and short term. These analysis showed that the farmers are price taker
Antihyperglycemic Activity of Piper crocatum Leaves and Cinnamomum burmannii Bark Mixture Extract in Streptozotocin-induced Diabetic Rats
Indonesia presently has the fourth largest diabetic mellitus prevalence of all countries in the world. In a previous study, a mixture extract of Piper crocatum leaves and Cinnamomum burmannii bark showed in vitro antihyperglycemic activity. It acted as inhibitor of the a-glucosidase enzyme and had no toxic effect when it was administered orally to male and female rats for 28 days. In the present study, mixture extracts of P. crocatum leaves and C. burmannii bark were used to observe antihyperglycemic activity in diabetic rats induced with streptozotocin. Mixture extracts of P. crocatum leaves and C. burmannii bark were orally given to diabetic Sprague Dawley rats at various doses for 16 days. The results showed that the treatment led to a reduction of the blood glucose level, an increase in blood insulin level up to 170.75% at 1260 mg/kg body weight, maintaining the blood lipid level of the diabetic rats at a normal level, and an increase of pancreatic ß cells in the islets of Langerhans up to 2.2-fold at 1260 mg/kg body weight. The mixture extracts of P. crocatum and C. burmannii have antihyperglycemic activity, which enhances the number of pancreatic β cells

Bone Marrow Profile in Haematological Disorders with reference to Flow Cytometry and RT-PCR in Acute Leukaemia
Introduction: Evaluation of non neoplastic and neoplastic haematological disorders require bone marrow examination which is an important diagnostic tool. This includes Bone Marrow Aspiration (BMA) and Bone Marrow Biopsy (BMB). Subtyping of Acute Leukaemia (AL) requires flow cytometry immunophenotyping and Real Time Polymerase Chain Reaction (RT-PCR), which helps in identifying cell antigens and genetic abnormalities, respectively. This is helpful to guide specific treatment for patients.
Aim: To evaluate the clinical profile, cytological and histological pattern of various haematological disorders using bone marrow examination and to determine immunophenotypes using ancillary techniques in patients with AL.
Materials and Methods: This was a cross-sectional observational study conducted in Department of Pathology, Sree Mookambika Institute of Medical Sciences, Kulasekharam, Tamil Nadu, India. Data was collected for a period of two years from May 2020 to April 2022. A total of 62 cases were included. Clinical details and bone marrow examination findings were noted for all BMA and BMB cases that satisfied the inclusion criteria and flow cytometry along with RT-PCR diagnosis was done for suspected AL cases. Analysis was done using Statistical Package for the Social Sciences (SPSS) version 20.0.
Results: Among the 62 cases studied, age of patients ranged from 32 to 81 years. Majority of them were in the 5th to 6th decade. Females 32 (51.6%) were more commonly affected. Pancytopenia 15 (24.2%) was the most common clinical presentation. Total 49 (79%) were diagnosed with BMA and 61 (98.4%) were diagnosed with BMB. Megaloblastic anaemia 16 (25.8%) and acute myeloid leukaemias 6 (9.6%) were the most common cause of benign haematological disorder and haematological malignancy respectively. The RT-PCR test for Break point Cluster-Abelson Tyrosine Kinase (BCR-ABL) and Promyelocytic Leukaemia-Retinoic Acid Receptor Alpha (PML- RARA) fusion gene analysis showed association in patients with Acute Lymphoblastic Leukaemia (ALL) and Acute Myeloid Leukaemia (AML) respectively.
Conclusion: Biopsy, being gold standard, provides details about the pattern, extent of tumour, metastatic deposit and granulomatous pathology, but BMA also proved better for study of the cell. Flow cytometry and RT-PCR were effective tools that enable the identification of immunophenotype in AL as well as to assess treatment progress and predict prognosis
