    Pinang merupakan komoditas unggulan di Provinsi Jambi. Peningkatan produksi tanpa diikuti dengan adanya tataniaga yang efisien tentu tidak akan mencapai tujuan pembangunan pertanian, tingginya biaya tataniaga cenderung akan menyebabkan perbedaan atau selisih harga yang diterima petani dengan biaya yang dibayar konsumen semakin besar. Penelitian ini bertujuan untuk mengetahui Structure Conduct Performance (SCP) tataniaga pinang pada pasar produsen di Kecamatan Muara Sabak Timur Kabupaten Tanjung Jabung Timur. Pemilihan lokasi dilakukan secara sengaja dengan pertimbangan bahwa Kabupaten Tanjung Jabung Timur merupakan salah satu penghasil pinang terbesar di Provinsi Jambi. Alat analisis yang digunakan untuk mengetahui struktur pasar digunakan metode deskriptif sedangkan alat analisis yang digunakan untuk mengetahui efisiensi pemasaran tiap saluran menggunakan metode analisis margin pemasaran dan analisis bagian harga yang di terima petani pada setiap saluran tataniaga, selanjutnya di analisis menggunakan metode analisis indeks efisiensi teknis dan indeks efisiensi ekonomis. Dari hasil penelitian diketahui sktruktur pasar mengarah kepada struktur oligopsoni. Hasil analisis diketahui bahwa besarnya bagian harga yang diterima petani pada saluran III lebih tinggi dibandingkan saluran I dan saluran II, untuk saluran III bagian harga yang diterima petani yaitu 82,13%, pada saluran II yaitu 65,92%, dan saluran I yaitu 59,71%. Secara teknis saluran III lebih efisien dibandingkan saluran lainnya dengan angka indeks efisiensi teknis terkecil yaitu sebesar Rp. 3,05/Kg/Km, saluran II yaitu Rp. 4,25/Kg/Km, dan saluran I yaitu 4,49/Kg/Km. Sedangkan secara ekonomis saluran yang efisien adalah saluran III sebesar Rp. 7,24/Kg, seterusnya saluran II sebesar Rp. 14,44/Kg, dan saluran I sebesar Rp. 17,29/Kg

    This work aims to study the effect of plastic deformation on the 7075 Al - alloy using Material Analyses Using Diffraction (MAUD). Plastic deformation produces dislocation defects. Using a hydraulic press, samples were deformed up to 25%. The XRD was measured for each degree of deformation. The MAUD program was used to analyze the data, and mathematical methods were deployed to understand the various behaviors observed. The lattice parameter, crystallite size, average internal stress, micro-strain, and dislocation density of the 7075Al-alloy were calculated. As the deformation degree increased, there was a progressive decline in the crystallite size as an increase in the micro-strain and dislocation density. The flow stress changes from 5.8 to 49 MPa and the stored dislocation energy varies from 2.62 to 185 kPa

    Stress and Failure Analysis of Double-Bolted Joints in Douglas-Fir and Sitka Spruce

    Stresses in, and strength of, single- and double-bolted mechanical joints in wood members are analyzed experimentally and numerically. The analyses account for the nonlinear geometric and stress-strain responses and the thicknesses of the members. Stresses are obtained using finite elements, strain gages, and moiré techniques. Failure is predicted from assumed strength criteria. Stresses and strength are influenced by end-distance, bolt-spacing, edge-distance, bolt-clearance, and load distribution between bolts of a multiple fastener. Predicted initiation of failure agrees with visible and audible damage initiation in full-scale components. These occur at 10 to 25% of ultimate structural strength

    This study aims to analyze how high the effect of translation approach to solve problems related to money story to the learning outcomes of students in class III SDN 16 South Pontianak. This study used a quasi-experimental methods (quasy experiments) with experimental designs Non ekuivalent Control Group Design. The study population was around the third grade students of SDN 16 South Pontianak. Research instrument in the form of tests with essay form as many as 10 questions. Data collection techniques used in this study using measurement techniques. Data processing gained an average pre-test control class 58.33 and the average pre-test experimental class 56.56. Post-test data analysis control class 62.95 and the average post-test experimental class 76.75. Results of hypothesis testing using t-test (polled Variance) was obtained (3.620> 1.6699), then the alternative hypothesis (Ha) is accepted.

    Improvements to deep convolutional neural networks for LVCSR

    Deep Convolutional Neural Networks (CNNs) are more powerful than Deep Neural Networks (DNN), as they are able to better reduce spectral variation in the input signal. This has also been confirmed experimentally, with CNNs showing improvements in word error rate (WER) between 4-12% relative compared to DNNs across a variety of LVCSR tasks. In this paper, we describe different methods to further improve CNN performance. First, we conduct a deep analysis comparing limited weight sharing and full weight sharing with state-of-the-art features. Second, we apply various pooling strategies that have shown improvements in computer vision to an LVCSR speech task. Third, we introduce a method to effectively incorporate speaker adaptation, namely fMLLR, into log-mel features. Fourth, we introduce an effective strategy to use dropout during Hessian-free sequence training. We find that with these improvements, particularly with fMLLR and dropout, we are able to achieve an additional 2-3% relative improvement in WER on a 50-hour Broadcast News task over our previous best CNN baseline. On a larger 400-hour BN task, we find an additional 4-5% relative improvement over our previous best CNN baseline.Comment: 6 pages, 1 figur

    The purpose of this investigation is to study the electrical properties of the YBCO/YSZ/Si metal‐insulator‐semiconductor structure and the yttria‐stabilized zirconia (YSZ)/Si interface. The YBCO and YSZ layers were epitaxially grown in situ on Si by pulsed laser deposition. Current‐voltage measurements of devices fabricated on p‐type Si(100) showed a small leakage current density at 292 K, which decreased further at 80 K. Comparison of capacitance‐voltage measurements at 292 K for frequencies between 10 and 400 kHz showed a large variation of capacitance in the accumulation region demonstrating the presence of mobile ions in the YSZ layer. This variation is less pronounced at 80 K. A negative shift of about 5 V in threshold voltage from 292 to 80 K has been attributed to redistribution of charges in the YSZ buffer layer
