Abstract

Power Quality menggambarkan kualitas daya listrik yang disuplai oleh jaringan listrik atau grid. Kualitas daya listrik sangat penting untuk diketahui dan diukur, terutama bagi perusahaan-perusahaan manufaktur. Masalah yang terjadi pada perusahaan biasanya sering dijumpai rusaknya peralatan elektronika yang sangat sulit ditemukan penyebab ataupun akar masalahnya. Pengukuran menggunakan power quality analyzer merupakan salah satu solusi mendapatkan hasil dari penyebab sering terjadinya kerusakan tersebut. Tujuan dari penulisan ini adalah untuk mengetahui dan menganalisis kondisi kualitas daya listrik pada perusahaan manufaktur dan memberikan rekomendasi serta solusi untuk memperbaiki dan meningkatkan kualitas daya listrik, sehingga dapat menghemat energi, mengurangi biaya, dan meningkatkan kinerja. Metodologi penelitian ini dengan melakukan pengukuran menggunakan power quality analyzer yang dipasang pada panel distribusi selama 24 jam. Dari hasil pengukuran didapat nilai tegangan dan arus masih dalam batas keseimbangan, nilai faktor daya masih dalam batas standar di 0,85, sementara terjadi distorsi harmonisa yang diperbolehkan SPLN yaitu < 5% dengan harmonisa tegangan THDV 5,3% dan harmonisa arus sebesar THDI L1 = 31,6%, L2 = 41,2%, dan L3 = 51,6%.  Dengan demikian, maka perlu dipasang filter harmonisa, untuk dapat menurunkan nilai harmonisa.

Abstract

This study aims to analyze the conditions of farm household food security levels and analyze the magnitude of the influence of factors such as farmer income, farmer education, farmer age, and number of family members on the level of food security of farm households in Sidorejo District, Salatiga City. This study uses data taken by survey methods and interviews with farmers as respondents. The number of samples used was 90 respondents, taken using the simple random sampling method in Pulutan Village, Kauman Kidul Village, and Blangkas Village as the areas where surveys and interviews were conducted with the largest number of farmer households registered in the Farmer Members Group in Sidorejo District. Data were analyzed using qualitative descriptive analysis, multiple linear regression analysis with the Ordinary Least Square (OLS) method, and the use of a proportion of food expenditure as an indicator for the level of food security of farm households. The analysis showed that statistically the factors of farmer income, farmer education, and the number of family members of the farmer had a significant effect on the level of food security of the household of the farmer, while the age factor of the farmer had no significant effect. Many as 55.56% of households have a proportion of food expenditure ≥ 60% or food insecurity. The rest, as much as 44.44% of households have food expenditure <60% or food security. Based on these results, the advice given is to increase farmers’ incomes by providing skills and training, as well as dissemination of policies on Sustainable Food Home Areas (KRPL).
