ANALISIS PERMINTAAN BERAS DI SUMATERA UTARA

Indonesia is often categorized as low food resilient nation, in the sense vulnerable to social unrest and rising global food prices. Where every year the number of requests or local domestic rice continue to increase along with the increasing number of people. This study aims to look at and determine how much influence the price of rice, corn prices and the number of population and GDP of the demand for rice in North Sumatra. Used in measuring and analyzing time series data (time series) and the cross-point (cross section) of the 25 districts / municipalities in the period from 2005 to 2010. Data analysis using fixed effects (fixed effect). The results showed a significant effect between the price of rice, the population and GDP of the demand for rice in North Sumatra. While corn prices do not influence of the demand for rice in North Sumatra. The magnitude of the effect is shown by the coefficient of independent variables, namely: -5.215489 for the variable price of rice, 13.08473 for the population, 4.736669 for the variable GDP.

Improve Food Security

Analysis of strengthen strategies of food rice security in Ogan Komering Ulu Regency is a bundle strategy to improve food security in dimensions of availability, stability and food access. This research was historical research.It used time series data, during 26 years period. Technique in collecting data used questionnaires. Data analysis used multiple regression analysis and SWOT matrix. Data presents in tables andpicture, as well as narration to interpret the data.The results of research showes that food security conditions in OKU regency still can meet the needs of rice. Adequacy of food availability, stability and access to food in OKU regency has a surplus of rice along 26 years period. This also shows that OKU regency is able to meet the needs of food rice. The factors that affect food security are (1) the availability of food with a variable land area, production and productivity, (2) stability with variable food consumption, food availability and food access, and (3) access to food that is variable income, the price of rice, the price of corn.Strategies undertaken to improve food security are doing expansion field and farming intensification, applying a single policy basic price of grain, local government policy to apply the regulation about land use, developing of farming with institutional concept, diversifying crops, reducing consumption rice, stabilizing food prices, and improving food reserves. It can be concluded thatstrategy of strengthening food security can be improved by implementing capabilities, minimizing shortage, maximizing opportunities, and overcoming the threats. This study suggest that government should follow the concept of food securitydevelopment and implement the strategy. ABSTRAK Analisis strategi penguatan ketahanan pangan beras di Kabupaten Ogan Komering Ulu adalah suatu strategi yang berfungsi untuk meningkatkan ketahanan pangan dengan dimensi ketersediaan, stabilitas dan akses pangan. Penelitian ini adalah penelitian bersifat historical (sejarah), menggunakan data runtun waktu (time series) yaitu selama kurun waktu 26 tahun. Teknik mengumpulan data menggunakan panduan kuisioner. Untuk analisis data menggunakan analisis regresi berganda dan matrik SWOT. Data disajikan dalam bentuk tabel dan gambar serta narasi untuk menginterpretasikan data tersebut. Hasil penelitian menunjukan bahwa kondisi ketahanan pangan di Kabupaten OKU masih dapat memenuhi kebutuhan beras masyarakatnya. Kecukupan ketersediaan pangan, stabilitas dan akses pangan yang ada di wilayah Kabupaten OKU mengalami surplus beras selama kurun waktu 26 tahun. Hal ini juga menunjukan bahwa Kabupaten OKU mampu mencukupi kebutuhan pangan beras masyarakatnya. Faktor-faktor yang mempengaruhi ketahanan pangan yaitu (1) ketersediaan pangan dengan variable luas lahan, produksi dan produktifitas, (2) stabilitas pangan dengan variable konsumsi, ketersediaan pangan dan akses pangan, serta (3) akses pangan variable yaitu pendapatan, harga beras, harga jagung. Strategi yang dilakukan untuk meningkatkan ketahanan pangan di Kabupaten OKU yaitu melakukan areal ekstensifikasi dan intensifikasi usahatani, menerapkan kebijakan tunggal harga dasar gabah, kebijakan pemerintah daerah untuk mengeluarkan peraturan tentang alihfungsi lahan, pengembangan usahatani dengan konsep kelembagaan, melakukan diversifikasi tanaman pangan, menurunkan tingkat konsumsi beras, menjaga stabilitas harga pangan, serta penguatkan cadangan pangan. Dapat disimpulkan bahwa strategi penguatan ketahanan pangan dapat ditingkatkan dengan menerapkan kemampuan, meminimalkan kekurangan, memaksimalkan peluang yang ada serta mengatasi ancaman yang menantang. Saran penelitian ini hendaknya pemerintah menindaklanjuti konsep pengembangan ketahanan pangan serta mengimplementasikan strategi tersebut.

Pooled Time Series

The study investigates how transitions in maternal unions are related to household food insecurity among a low-income sample using pooled time series data from the Early Childhood Longitudinal Survey–Birth Cohort. Pooled time series fixed effects models indicate that transitioning into unions for White and Hispanic households is associated with reductions in household food insecurity compared with White and Hispanic households who experienced no transitions. Furthermore, transitioning into unions for Hispanic households is associated with reductions in household food insecurity status compared with Hispanic households that experienced dissolving unions. Last, results indicate that maternal union transitions are not related to household food insecurity status of Black and Other race and ethnic households. The authors discuss how the findings may be related to socioeconomic factors of race and ethnic households.

Purpose – The purpose of this paper is to analyze the profitability of 27 universal banks in Portugal over the period from 2002 to 2011. Design/methodology/approach – The paper conducts ordinary least squares estimations with fixed effects using three measures of profitability: the return on average assets, the return on average equity and the net interest margin. Several independent variables were included concerning both bank-specific and macroeconomic and industry-specific characteristics which have not been considered in previous studies. In addition, the sub-sample between 2008 and 2011 was considered for comparative analysis. Findings – The authors concluded that the independent variables selected, with few exceptions, behaved accordingly to what was expected. Originality/value – To the best of the author’s knowledge, this is the first attempt to examine determinants of banks’ profitability in Portugal, both internal and external, using time series data, which have not been considered in previous studies.

Short Time

This paper describes interfuel substitution for liquid fuel, coal and electricity in Zimbabwe manufacturing and mining using a translog cost function. Our data series spans over a 24 year period. To mitigate the short time span of this time series data, we partially pool time-series cross-section observations, and take into account the ‘random effects’ and ‘fixed effects’ framework in estimating regression equations. Estimated results are used to determine possibilities for interfuel substitution particularly given persistent increases in the price of liquid fuel. We use an aggregated demand approach as this should both sharpen our results and yield more efficient estimates.

Introduction: This research was aimed to determine the relationship pattern of rainfall, humidity, and rainy day on the increase in pepper yield in North Sumatra. Materials and Methods: This research used the time-series data on factors of rainfall, humidity, rainy day, and yield of pepper for 14 years (2005 until 2018). Data analysis used the multiple linear regression analysis with the Eviews 10 software. Results: The rainfall, humidity, and rainy day simultaneous significantly increased the pepper yield of 55.767% in North Sumatra. A 1% increase in humidity can increase the pepper yield by 0.455 ton, but a 1 mm.year-1 increase in rainfall and a 1 rainy day can decrease the pepper yield in North Sumatra by 0.503 and 1.866 ton, respectively. The humidity had the value positive, meanwhile rainfall and rainy day had the value negative in pepper yield.
