Abstract

Permasalahan tenaga kerja di Sumatera Utara merupakan masalah yang mendapat perhatian menyeluruh dan terpadu. Salah satu esensi terpenting dalam pembangunan ekonomi adalah penyediaan lapangan kerja yang cukup untuk mengimbangi pertambahan angkatan kerja yang akan masuk ke pasar kerja. Penelitian ini menggunakan data sekunder berbentuk data time series dan dianalisis dengan menggunakan model persamaan linier berganda. Hasil uji model secara serentak menjelaskan bahwa masing. masing variabel memberikan pengaruh positip terhadap lapangan kerja sektoral di Sumatera Utara dan khusus pada IHK adalah positif, tetapi tidak signifikan. Hal ini menunjukkan bahwa inflasi memberi dampak yang serius bagi kesejahteraan dan tidak memberi pengaruh terhadap pertumbuhan angkatan kerja secara nyata, sehingga dianggap inflasi membebani tingkat kehidupan masyarakat karena salah satunya tingkat upah tetap. Pemerintah Daerah Propinsi Sumatera Utara diharapkan lebih serius lagi dalam memperhatikan perkembangan sektor primer dimana sektor ini memiliki berbagai keunggulan dibandingkan sektor lain, seperti penyerap angkatan kerja, penyedia kebutuhan pokok atau juga penyedia bahan baku kebutuhan industri serta sumber modal untuk pertumbuhan ekonomi Propinsi Sumatera Utara yang akan datang.Kata Kunci : tenaga kerja, Sumatera Utara, pertumbuhan ekonomi, sektor ekonomi

This shows the marketing channel 3 is more efficient than marketing channels 1, 2 and 4 . However, based to the amount of red chili farmers who choose to use channel 3 is lower than channels 1 and 2 . So operationally channel 3 is not necessarily more efficient because it is only used by 18.57 % of the farmers while channel 1 at 42.85, and channel 2 at 25.71 %. The role of stakeholders to improve the income of farmers through efficient marketing channels is needed. Government efforts are needed to increase their knowledge of processing technologies in the long term so that farmers are able to cultivate chili production in the form of home industry Keywords : efficiency, marketing, chili

The aim of this research into analysis production factors to production level and to analysis conducting operating revenues crab culture (Scylla sp) at Sei Lepan Sub-district in Langkat District. Method that is utilized is logistic production Cobb Douglass and data that is utilized is crab farmer production and income data up to a year 2012. Analysis result Cobb Douglass point out that logistic model estimation production which is: Ln Prod = 0,040 + 0,022 Ln Ll – 0,102 Ln Tkdk + 0,005 Ln Tklk + 0,995 Ln Bb. Its outgrows appreciative Return to Scale (RTS) are 0,92. So RTS< 1 (Decreasing return to scale). Determinant coefficient 0,990 explain that percentage of independent variable regard dependent's variable as big as 99,0% and hypothesis that declares for that variable stocks down and far ranging positive ascendant farm and signifikan to soft shell crab production (Scylla sp) accepted. Income average crab farmer soft shell crab (Scylla sp) year long production as big as Rp. 11.709.511,- .
