Abstract

Penggunaan minyak kelapa sawit terus meningkat seiring dengan pertumbuhan penduduk dunia. Perkembangan teknologi produksi dan peningkatan tingkat konsumsi penduduk, diperkirakan bahwa penggunaan minyak kelapa sawit akan terus meningkat. Penelitian ini bertujuan untuk mengetahui pengaruh luas lahan dan produktivitas terhadap hasil produksi kelapa sawit. Adapun metode yang digunakan adalah metode Cobb Douglass. Berdasarkan hasil pengolahan data diperoleh hasil uji asumsi klasik menunjukkan bahwa pengaruh luas lahan dan produktivitas terhadap hasil produksi kelapa sawit terbebas dari gejala multikolineritas, autokorelasi, heteroskedastisitas dan normalitas. Hasil koefisien determinasi dapat dijelaskan bahwa presentase sumbangan pengaruh yang diberikan variabel independen terhadap variabel dependen sebesar 99,6%. Pengolahan data menggunakan software SPSS versi 16.0 diperoleh  kesimpulan bahwa luas lahan dan produktivitas memiliki pengaruh terhadap hasil produksi kelapa sawit AbstractThe use of palm oil continues to increase along with the growth of the world's population, the development of production technology and the increase in the level of population consumption, it is estimated that the use of palm oil will continue to increase. This study aims to determine the effect of land area and productivity on oil palm production. The method used is the Cobb Douglas method. Based on the results of data processing, the classical assumption test results show that the effect of land area and productivity on oil palm production is free from the symptoms of multicolinearity, autocorrelation, heteroscedasticity and normality. The results of the coefficient of determination can be explained that the percentage contribution of the influence given by the independent variable to the dependent variable is 99.6%. Data processing using SPSS version 16.0 software, it can be concluded that land area and productivity have an influence on oil palm production.

Abstract

Penelitian ini bertujuan untuk menentukan jumlah omset berdasarkan jumlah nasabah, inflasi dan kurs di Pegadaian Syariah Cabang Subrantas Unit Sidomulyo Pekanbaru. Teknik analisa yang digunakan studi ini adalah Metode Fuzzy Tsukamoto yang merupakan salah satu Fuzzy Inference System. Penelitian diawali dengan pembentukan aturan dan himpunan fuzzy, lalu dicari nilai z untuk setiap aturan dengan menggunakan fungsi MIN pada aplikas fungsi implikasinya, kemudian dicari nilai keakuratan atau Mean Absolute Percentage Error (MAPE) dari omset. Hasil penelitian ini menunjukkan bahwa prediksi jumlah omset dengan nilai keakuratan mencapai 84,4098%.AbstractThis study aims to determine the amount of turnover based on the number of customers, inflation and the exchange rates at the Pegadaian Syariah Branch Subrantas Sidomulyo Unit Pekanbaru. The analysis technique used in this study is the Tsukamoto Fuzzy Method which is one of the Fuzzy Inference Systems. The research begins with the formation of fuzzy rules and sets, then looks for the z value for each rule by using the MIN function in the application of the implication function, then looks for the accuracy value or Mean Absolute Percentage Error (MAPE) of the turnover. The results of this study indicate that the prediction of turnover with accuracy reaches 84.4098%.

Abstract

Various problems be facing by the company to get optimal results. One of them in this research is to optimize cost, time and quality simultaneous to get a minimal solution. The optimization of these problems uses the Hungarian method by applying multi-objective assignments. Based on the of the optimal solution results from one-objective, two-objective and three-objective assignments, these third-objective assignment is the best result. So that in the case example, the optimal solution is obtaining where the total cost incurred is Rp. 24,950,000. The total time required is 96 days. While the quality of the rattan flower vase is very good, the decorative lighting is very good and the mat is very good, the shelf is very good, the table is very good, the wardrobe is very good and the guest chair is very good.
