ANALISIS EFISIENSI PENGGUNAAN FAKTOR – FAKTOR PRODUKSIPADA USAHA TANI PADI DI KECAMATAN PEKALONGAN SELATAN

Penelitian ini bertujuan untuk mengetahui pengaruh dari faktor – faktor produksi seperti luas lahan, bibit, pupuk, pestisida dan tenaga kerja terhadap hasil produksi tanaman padi, khususnya di wilayah Kecamatan Pekalongan Selatan Kota Pekalongan. Penelitian ini juga untuk mengetahui apakah skala produksi usaha tani padi berada dalam skala produk yang naik, serta untuk mengetahui apakah usaha tani padi yang dilakukan petani sudah mencapai tingkat efisiensi Sehubungan dengan masalah tersebut maka diajukan hipotesis sebagai berkikut : Pertama, Diduga bahwa faktor- faktor produksi berpengaruh terhadap hasil produksi usaha tani padi di Pekalongan selatan.Yang kedua diduga bahwa proses produksi usaha tani padi di Pekalongan Selatan berada dalam keadaan skala produk yang naik ( increasing return to scale ). Serta yang ketiga diduga bahwa penggunaan faktor - faktor produksi tersebut belum efisien Penelitian ini menggunakan data primer dengan mengambil sampel sebanyak 87 responden petani padi di Kecamatan Pekalongan Selatan. Sejalan dengan masalah tersebut dan hipotesis penelitian, maka penelitian ini dilaksanakan dengan metode fungsi produksi Cobb – Douglass, perhitungan skala hasil produksi serta efisiensi. Hasil dari analisis menunjukan bahwa faktor - faktor produksi seperti: luas lahan, bibit, pupuk, pestisida, serta tenaga kerja secara parsial dan bersama - sama berpengaruh positif tehadap hasil produksi tanaman padi. Dari penjumlahan elastisitas faktor – faktor produksi diperoleh nilai sebesar 0,97. Maka produksi usaha tani padi di Kecamatan Pekalongan Selatan menunjukan skala hasil yang menurun atau dereasing return to scale, yaitu setiap penambahan faktor produksi 1% maka akan meningkatkan produksi kurang dari 1%. Penggunaan semua faktor produksi belum mencapai tingkat efisiensi karena nilai MPP yang lebih besar dibanding nilai Px / Py dari masing - masing variabel independen. Saran – saran yang diberikan berdasarkan hasil penelitian tersebut adalah bahwa para petani harus lebih mengoptimalkan dan memperhitungkan faktorfaktor produksi yang dipakai dan hasil yang diperoleh supaya tercapai tingkat efisiensi. Para petani dalam menggunakan tenaga kerja dalam proses produksi hendaklah yang efektif karena banyaknya pekerja yang tidak sesuai dengan kebutuhan akan berdampak pada pemborosan biaya produksi. Selain itu peranan pemerintah juga penting, misalnya dengan memberikan kemudahan fasilitas dalam usaha tani agar para petani tidak meninggalkan sektor pertanian mengingat minimnya minat generasi muda yang mau terjun ke sektor pertanian Kata Kunci : Efisiensi ekonomis, Skala hasil, Usaha tani padi.
Changes in cross sectional area per myonucleus on mice soleus muscle during one week of hindlimb suspension reinforce the concept of myonuclear domain

Objective: The effects of hindlimb unweighting by tail suspension on mice’s soleus muscle cross-sectional area (CSA) and myonuclei content were studied. Design: Five groups of male Charles River CD 1 mice (n=10 per group) were assigned to varying hindlimb suspension (HS) periods: control (cont), 1 (1HS), 2 (2HS), 3 (3HS) and 8 (8HS) days. Immediately after the suspension period, the soleus muscles were removed in order to assess morphometry data. The CSA and number of myonuclei were determined in a total of 5011 fibers (1098, 793, 1363, 1281, 1276 fibers for the cont, 1HS, 2HS, 3HS, 8HS groups, respectively) from different areas in the mid-portion region of the soleus muscle, and the CSA per myonucleus ratio was calculated. Results: The results showed that the removing of weight bearing had a negative impact on muscle fiber CSA (1686 ± 516 µm 2 , 1506 ± 470 µm 2 , 1235 ± 340 µm 2 , 1277 ± 412 2 in the cont, 1HS, 2HS, 3HS and 8HS groups, respectively) and myonuclei number per fiber (1.91 ± 1.17, 1.94 ± 1.30, 1.55 ± 1.01, 1.48 ± 1.00 and 0.83 ± 0.76 in the cont, 1HS, 2HS, 3HS and 8HS groups, respectively). The CSA per myonucleus ratio was 993 ± 522 µm 2 , 854 ± 443 µm 2 , 815 ± 374 µm 2 , 881 ± 442 µm 2 and 957 ± 367 µm 2 in the cont, 1HS, 2HS, 3HS and 8HS groups, respectively. Thus, there were no significant differences between the control and 8HS groups. Conclusion: The morphological data is consistent with the hypothesis that, despite the muscle fiber atrophy induced by HS, the CSA per myonucleus ratio is apparently maintained, reinforcing the concept of myonuclear domain.

Studies on C 2 n and its effects on free space optical communication system

With the emergence of new innovative wireless technologies, there is an increased demand for technologies to provide high speed seamless connectivity between two places. Compared with radio frequency communication, free space optical communication has many advantages. It can provide very high speed communication services. But it is deeply influenced by the atmosphere turbulence, when used in terrestrial application. It is very important to do some researches on the atmosphere turbulence and its effects on the free space optical communication. We have used an experimental free space optical communication system to measure the characterization of atmosphere turbulence. In this paper we mainly analyze the experiment data of atmosphere turbulence. We also review the theory of atmosphere turbulence and analyze the relation with the characterization of atmosphere turbulence and the receiving power of the free space optical system. From the data we found that the atmosphere turbulence changed with time and weather. And we get some results from analyze the experiment data. The results from the experiment are very important in the design optimization of free space optics system performance in actual operational environments.

Punching shear strength of RC flat slabs at interior connections to columns

A method to evaluate the punching shear strength of reinforced concrete (RC) flat slabs without shear reinforcement at the connection to interior columns is proposed. The method is based on the assumption that the punching shear strength is controlled by the inclination of a unique punching shear crack that produces a conical failure surface. The inclination angle of the crack is variable. It follows that the location of the critical section is not established in advance, but changes with crack angle. Its location depends on the reinforcement ratio, material strengths and effective depth. According to the proposed method, the punching shear strength is a function of the inclination angle of the governing crack that controls the amount of shear carried by the compression zone and the flexural reinforcement crossing the potential punching cone by accounting for its slenderness and concrete size effect. The method describes the behaviour observed in tests and numerical and analytical investigations. The nove.
Estimating Correlations from Scatterplots

Previous attempts to establish the function relating intuitive estimates of correlations from scatterplots to accepted statistical measures have led to unsatisfying results. In this study two experiments dealt with the effects of the statistical training of the viewer and various characteristics of the display on estimates. Statistical knowledge was related to higher estimates of correlations and the use of a wider range of values, but people with and without statistical knowledge were equally affected by the type of dispersion of the point cloud, the mere display of the regression line, and the slope of the regression line. Results indicate that estimates of correlations from scatterplots are partly based on perceptual processes that are influenced by visual properties of the display and are unrelated to the cognitive structures created by formal statistical training.
Spatial Pattern Analysis on Dengue Cases in Bangi district, Selangor, Malaysia

Background: Dengue outbreak has proliferated around the developing countries, including Malaysia, in recent decades. Thus, understanding the distribution pattern is essential for urbanization livelihood. Method: The objective of this study is to determine the trend of dengue cases reported from year 2014 to 2018 and the spatial pattern for dengue spread with reference to weather elements in Bangi town. Results: Spatial statistical analyses conducted found that the distribution pattern and spatial mean center for dengue cases was clustered at the east of Bangi region. Directional distribution observed that the elongated polygon of dengue cluster stretched from the northeast to the southwest of Bangi district. Standard distance for dengue cases was the smallest for the year 2014 (0.017 m), and the largest was in the year 2016 (0.019 m), whereas dengue cases in year 2015, 2017, and 2018 were measured at 0.018 m. The average nearest neighbor analysis also observed clustered patterns for dengue cases in Bangi district. Pearson’s correlation analysis found that temperature (r = -0.269) was negatively correlated with dengue cases for year 2014 and 2018; however, rainfall amount (r = 0.286) and rain days (r = 0.250) were positively correlated with dengue cases in year 2018.Conclusions: The three spatial statistical analyses (spatial mean center, standard distance, and directional distribution) findings illustrated that the dengue cases from the year 2014 to 2018 are clustered on the northeast to the southwest of the study region. The rainfall element is found to be a significant positive factor correlated for most study years compared to temperature element.
Upregulation of microRNA-96 alleviates the neurological damage in acute seizure rats by down-regulating RAC1 and inhibiting the activation of RhoA/ROCK signaling pathway

Objective Today, the research about the involvement of non-coding RNAs on neurological disorders is still scarce. Hence, we aimed to investigate the effect of miR-96 targeted RAC1 to mediate RhoA/ROCK signaling pathway in neurological damage in acute seizure rats.MethodsThe acute seizure rat model was constructed by using classical chlorinated-pilocarpine injection, which was treated with miR-96 mimics, RAC1-siRNA or their controls. The number of BrdU positive cells, neuronal changes and apoptosis, expression of NGF, BDNF and GFAP were detected by different staining assays. At the same time, the activity of SOD, the content of MDA and the protein contents of TNF-α and IL-6 in rat hippocampus were detected as well. Next, the expression of NGF, BDNF, GFAP, Bax, Bcl-2, caspase-3, RAC1, RhoA and ROCK were determined by RT-qPCR and western blot analysis. Then, the binding site between miR-96 and RAC1 was analyzed by bioinformatics software and luciferase assay. Finally, the altered expression of miRNAs was investigated in exosomes released from excitotoxic neurons with a customized rat miRNA chipset.Results After upregulation of miR-96 or downregulation RAC1, BrdU-positive cells, TUNEL-positive cells, NGF, GFAP, MDA, TNF-α, IL-6, Bax, caspase-3, and pathway related proteins in rat hippocampus decreased while Bcl-2, BDNF, and the activity of SOD increased. Furthermore, RAC1 was found to be the target gene of miR-96 and their relationship was validated in in-vitro studies. Finally, the decreased expression of miR-96 in exosomes from kainic acid treated neurons was identified as well.Conclusion This study suggests that upregulation of miR-96 could downregulate RAC1 and inhibit the activation of RhoA/ROCK signaling pathway, thus alleviated the neurological damage in acute seizure rats.
The physics of superconducting microwave resonators

Over the past decade, low temperature detectors have brought astronomers revolutionary new observational capabilities and led to many great discoveries. Although a single low temperature detector has very impressive sensitivity, a large detector array would be much more powerful and are highly demanded for the study of more difficult and fundamental problems in astronomy. However, current detector technologies, such as transition edge sensors and superconducting tunnel junction detectors, are difficult to integrate into a large array. The microwave kinetic inductance detector (MKID)is a promising new detector technology invented at Caltech and JPL which provides both high sensitivity and an easy solution to the detector integration. It senses the change in the surface impedance of a superconductor as incoming photons break Cooper pairs, by using high-Q superconducting microwave resonators capacitively coupled to a common feedline. This architecture allows thousands of detectors to be easily integrated through passive frequency domain multiplexing. In this thesis, we explore the rich and interesting physics behind these superconducting microwave resonators. The first part of the thesis discusses the surface impedance of a superconductor, the kinetic inductance of a superconducting coplanar waveguide, and the circuit response of a resonator. These topics are related with the responsivity of MKIDs. The second part presents the study of the excess frequency noise that is universally observed in these resonators. The properties of the excess noise, including power, temperature, material, and geometry dependence, have been quantified. The noise source has been identified to be the two-level systems in the dielectric material on the surface of the resonator. A semi-empirical noise model has been developed to explain the power and geometry dependence of the noise, which is useful to predict the noise for a specified resonator geometry. The detailed physical noise mechanism, however, is still not clear. With the theoretical results of the responsivity and the semi-empirical noise model established in this thesis, a prediction of the detector sensitivity (noise equivalent power) and an optimization of the detector design are now possible.
Ship Turn-Around Time at the Port of Bangkok

An analysis is given of data pertaining to ship turn-around time at the Port of Bangkok from the standpoint of queuing theory. Ship arrivals for a full year were studied and an arrival-distribution function selected. The servicing-distribution function of the 1,215 ships which used berths during the year was obtained. The problem was to determine the average waiting time for ships arriving from sea, and the average number of ships waiting at the bar for a berth. As the formulas for multiple-channel queuing models for exponential arrival and Erlangian servicing are intractable, three approximations were studied. Two of these were found to give reasonable results when compared with the known values of waiting time and queue length. Inferences were drawn regarding the effect of expected growth of traffic on waiting times and the number of ships waiting at the bar in the future.

Blended learning: Issues, benefits and challenges

This paper discusses the use of 'blended' learning where the use of traditional lectures and tutorials is supplemented, and often replaced to some extent, by new approaches to learning such as computer and on-line simulations, and other interactive on-line packages designed to cover more basic aspects of the curriculum (or provide remedial support) in the students' own time. It reviews some of the reasons for the introduction of blended learning and addresses the potential benefits and some of the potential issues that need to be considered when using innovative teaching strategies in a blended learning setting. The authors draw from examples of their experiences with blended learning. It is argued that new approaches to teaching such as student centred and blended learning offer considerable possibilities to enhance the student experience, but only if proper attention is paid to integrating the 'new' and 'old' aspects of the teaching program, as well as to the development of appropriate administrative systems and support.
Focused Application Software for Ferrite Patch Antennas

Abstract : The objective of this Phase 2 effort was to develop computational electromagnetic (CEM) codes capable of modeling the radiation properties (pattern, input impedance, efficiency, and bandwidth) of conformal arrays printed on ferrite substrates or superstrates. The codes developed under this effort model inhomogeneous ferrites and dielectrics, non-planar surfaces, heterogeneous elements, complex feed mechanisms, and performance control devices such as shorting pins and lumped loads. The FE-BI codes (brick and tetrahedral elements) are combined by MRC via a graphical user interface (GUI) into a user friendly code capable of modeling conformal antennas with ferrite sub and superstrates recessed in planar surfaces.
Predicting the Perceptual Acceptability of Auditory Interference for the Optimisation of Sound Zones.

This work is part of the Perceptually Optimised Sound Zone project (posz.org) which aims to develop sound zoning systems which reproduce audio programmes to multiple listening zones within automotive and domestic environments. This work describes the construction of a model to evaluate sound zoning systems. A framework for evaluating auditory interference scenarios is described in which either the target or interferer programme is masked, or where both programmes are audible and the listening scenario has some degree of acceptability. Masking and acceptability experiments were conducted to investigate the relationship between the two, and to determine boundaries of audibility. A linear correlation was found between masking and acceptability, and a linear regression model was constructed to predict thresholds of acceptability from masking thresholds. A masking threshold model was adapted and predictions were within 3 dB of the reported mean masking thresholds. Predictions of acceptability, using a linear regression and masking model combination, accounted for three quarters of the variance in acceptability. Further work focused on speech target programmes based on listener comments that the presence of speech a? ected acceptability. An experiment was conducted to gather intelligibility and acceptability data. Results showed that a high speech intelligibility marked the lower boundary of acceptability. Existing models for intelligibility prediction were evaluated and a time-windowed speech intelligibility index was shown to predict intelligibility with RMSE = 10.8%. Subsequently, a model was constructed to predict acceptability within these boundaries. Two experiments were conducted gathering training and validation data, and a training and selection procedure was carried out to methodically identify the most useful features. The selected model predictions had acceptability scores of RMSE = 11.1? 17.9% across training and validation data. Finally, an algorithm was proposed for the prediction of acceptability in auditory interference scenarios. The algorithm consists of ? rst predicting masking thresholds to determine the boundaries of acceptability. Then, for non-speech target programmes, the acceptability is predicted using a linear regression to the masking threshold; for speech target programmes, the intelligibility is calculated to revise the lower acceptability boundary and the speech acceptability model is used to predict acceptability.

Application of a Dielectric Resonator on Microstrip Line for a Measurement of Complex Permittivity

A cylindrical dielectric resonator placed on microstrip line is used for measuring the complex permittivity of microwave low-loss high epsilon/sub r/ dielectric materials. The method is based on the accurate solution of this resonator with TE/sub 01delta/ mode and is compared to the method of dielectric rod resonator with TE/sub 11/ mode. The accuracy of the both method is similar - the measurement accuraoy of relative dielectric constant is better than 0.2 percent and measurement accuracy of loss tangent is about 1·10/sup -4/.
