Analisis Struktur Perilaku Dan Kinerja Pasar (Structure, Conduct and Market Performan) Komoditi Padi Di Desa Bunga Raya Dan Desa Kemuning Muda Kecamatan Bunga Raya Kabupaten Siak

Penelitian ini bertujuan untuk menganalisis struktur, perilaku, dan kinerja pemasaran beras di Kabupaten Bunga Raya. Lokasi penelitian ditentukan dengan menggunakan metode purpossive sampling yaitu dua desa menjadi sentra produksi padi. Responden penelitian adalah petani padi dan semua agensi pemasaran yang terlibat dalam pemasaran beras dari petani sebagai produsen ke pedagang besar sebagai konsumen. Hasil penelitian menunjukkan ada tiga saluran pemasaran beras yaitu saluran pemasaran I petani menjual kepada pedagang pengumpul dan kemudian dijual ke pedagang besar, saluran pemasaran II petani menjual ke pedagang pengumul yang memiliki penggilingan padi kemudian dijual ke pedagang grosir dan saluran pemasaran III yaitu petani menjual langsung ke pedagang grosir. Struktur pasar beras adalah pasar oligopsoni karena dilihat dari jumlah pembeli yang relatif sangat sedikit, kemudian dilihat dari nilai market share, rasio konsentrasi dan indeks Herfindahl dari pedagang manapun menunjukkan nilai yang tidak terlalu berbeda. Petani sebagai produsen adalah penerima harga (price taker), dimana petani sebagai produsen mendapatkan Perubahan nilai harga lebih kecil dibandingkan dengan pedagang grosir sebagai konsumen. Margin pemasaran terlihat dari setiap saluran pemasaran yang terjadi menunjukkan bahwa margin dan keuntungan paling banyak didapat oleh pedagang yang melakukan lebih banyak fungsi pemasaran

Metallic Cylinder Reflected Power Measurement For 93.1GHz Frequency Modulated Continuous Wave Radar Calibration

A metallic cylinder is one of the best materials and shapes to calibrate a radar system performance. The measurement of a 4cm diameter and 3cm-height metallic cylinder as a target has been presented for the analysis at the millimeter-wave (mm-wave) spectrum. This experiment was conducted in a real airport environment at Kuala Lumpur International Airport considering clear sky conditions. The measurement was carried out at 93.1 GHz which uses Frequency Modulated Continuous Wave (FMCW) radar to consistently detect the target. The radar cross-section (RCS) of the metallic cylinder is measured with respect to the angle of runway pavement. It is found that the measurements exhibited smaller RCS value with an average of –43.47 dBsm at a longer range compared to –30.16 dBsm at a shorter range with a total change of 13.31 dBsm. The reflectivity characteristics of the radar target, theoretical measurement of the metallic cylinder, its incident angle from the radar target, and measurement evaluation are presented in this paper

Metal concentration at surface water using multivariate analysis and human health risk assessment

This study defined the concentration of metals in Kerteh and Paka River water and their potential health risk towards human. 54 water samples were collected and analyzed using ICP-OES. Results revealed that most of the stations in Kerteh River gave the higher concentration of Cd, Cu, Zn, Co, Ni, As, Cr and Pb compared to Paka River. However As, Cr and Pb have exceeded the permissible limit of Malaysia standard for all stations in both rivers. Cd, Cu, Zn, Co and Ni were below than Malaysian standard permissible levels during the sampling period. The principal component analysis (PCA) revealed that both geogenic and anthropogenic sources were responsible to possible metals contamination in both rivers. Moreover, risk assessments for all metals were within the safe limits, except for As in the Kerteh River for both adult and child as well as to Paka River for both genders

Caribbean Corals in Crisis: Record Thermal Stress, Bleaching, and Mortality in 2005

BACKGROUND The rising temperature of the world's oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin. METHODOLOGY/PRINCIPAL FINDINGS Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers' field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality exceeded prior efforts in detail and extent, and provided a new standard for documenting the effects of bleaching and for testing nowcast and forecast products. Collaborators from 22 countries undertook the most comprehensive documentation of basin-scale bleaching to date and found that over 80% of corals bleached and over 40% died at many sites. The most severe bleaching coincided with waters nearest a western Atlantic warm pool that was centered off the northern end of the Lesser Antilles. CONCLUSIONS/SIGNIFICANCE Thermal stress during the 2005 event exceeded any observed from the Caribbean in the prior 20 years, and regionally-averaged temperatures were the warmest in over 150 years. Comparison of satellite data against field surveys demonstrated a significant predictive relationship between accumulated heat stress (measured using NOAA Coral Reef Watch's Degree Heating Weeks) and bleaching intensity. This severe, widespread bleaching and mortality will undoubtedly have long-term consequences for reef ecosystems and suggests a troubled future for tropical marine ecosystems under a warming climate.This work was partially supported by salaries from the NOAA Coral Reef Conservation Program to the NOAA Coral Reef Conservation Program authors. NOAA provided funding to Caribbean ReefCheck investigators to undertake surveys of bleaching and mortality. Otherwise, no funding from outside authors' institutions was necessary for the undertaking of this study. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript

The inclusion of fisheries and tourism in marine protected areas to support conservation in Indonesia

With the rapid growth of Indonesia’s marine protected area (MPAs) estate in Indonesia, reaching 23.9 million hectares by January 2020, attention needs to be focused on strengthening the effectiveness of MPA management. Consolidating and expanding protection of Indonesia’s marine resources is critical with increasing pressure from a fast-expanding population, illegal, unreported, and unregulated fishing, pollution, coastal development, unsustainable tourism and climate change. Biodiversity conservation must therefore concurrently consider multiple economic sectors such as fisheries and tourism, and their synergies with MPA management. This paper aims to outline the current landscape of fisheries and marine tourism pertaining to area-based conservation in Indonesia, to inform and support improved integration into effective MPA management. Four areas to focus efforts were identified: diversification of governance types of community-based management, improved coordination between fisheries and MPAs during planning and management implementation, the development and support of pathways for sustainable tourism, and planning for future conditions. Sustainable development for fisheries and tourism must be incorporated into all aspects of MPA management, whilst recognising that current management systems are insufficient to ensure long-term sustainability for natural resources and local communities, and strategies need to increase resilience of social-ecological systems in anticipation of future conditions
