Abstract

PT. XYZ yang merupakan perusahaan yang bergerak di bidang perakitantransformator, yang berproduksi berdasarkan pesanan (make-to-order). Masalah yang terjadidi perusahaan ini masih adanya pembagian beban kerja dan kapasitas mesin/operator yangtidak seimbang pada proses perakitan masing-masing stasiun kerja yang akan berpengaruhterhadap kelancaran produksi. Selain itu proses produksi yang ada di lantai produksi belumterlaksana secara optimal dimana terdapat penumpukan bahan di beberapa stasiun kerja.Untuk menyelesaikan permasalahan ini dibutuhkan penyeimbangan lintasan perakitan.Penyeimbangan lintasan perakitan dilakukan dengan menggunakan metode heuristik MoodieYoung dan COMSOAL. Tujuan dari penelitian ini adalah untuk mendapatkan rancangankeseimbangan lintasan yang baik dan memberikan gambaran adanya perbedaan kondisi daristasiun kerja sebelum dan sesudah dilakukan penyeimbangan. Hasil penelitian menunjukkanbahwa metode Moodie Young dan metode COMSOAL memiliki nilai balance delay danefisiensi lintasan produksi yang sama baiknya yaitu masing-masing sebesar 46,89% dan53,21%. Nilai smoothness index untuk metode Moodie Young sebesar 367,86 sedangkanuntuk metode COMSOAL sebesar 368,42. Maka yang menjadi metode usulan adalah metodeMoodie Young. Dalam penelitian ini, dilakukan penentuan jumlah operator dan mesin.Hasilnya dilakukan penambahan 1 mesin dan 1 opertaor pada stasiun kerja VI (PenggulunganCoil), VII (Koneksi Kumparan), dan IX (Proses Akhir).

Abstract. A company making palm olein find the results of the productionprocess has some variation of the characteristics of the oil, which is a variation ofcolors, smells, acid number and moisture content. Variations occur due to theheating temperature in the engine Slurry Tank, spiral heat exchange machines anddeodorize machine that changed the conditions required. This resulted in financiallosses for the company. The research was conducted by examining thecharacteristics of the oil, which aims to get real-time comparison of thecharacteristics and expectations of the value characteristics of color, odor, acidnumber and moisture content. Furthermore, the interviews and the cost of losscalculation using the Taguchi Quality Loss Function to improve the characteristicsof the product which is not according to specifications. Research shows loss costper color characteristics of 0.099%, the characteristic odor of 0.077%, thecharacteristics of acid number of 0.1% and the characteristics of the water contentof 0.0002%. While the total cost of loss to Rp 269 319 600 / year. If doneimprovement of production processes, then the resulting cost reductionsamounting to 18.65% or USD 50.2524 million / year. The losses reached 18.65%showed losses during the company is quite large, so it is necessary improvementof the production process to minimize lost production costs.Keywords: Cooking Palm Oil, Taguchi Quality Loss Function, ProductCharacteristics, Production Cost

Abstract

Penelitian ini berjudul Analisis penetapan nilai pengganti wajar dalam pembebasan tanah untuk kepentingan umum di Kota Lhokseumawe (Studi Kasus Pembuatan Jalur Rel Kereta Api Di Kecamatan Muara Dua Kota Lhokseumawe). Pembangunan suatu wilayah di Indonesia saat ini dilatarbelakangi terbatasnya ketersediaan dan daya tampung tanah untuk pembangunan yang diakibatkan oleh pertumbuhan dan distribusi penduduk. Disamping semakin meningkatnya kegiatan kehidupan sosial ekonomi masyarakat wilayah yang tercermin dalam bentuk perluasan ruang wilayah meningkat pula. Dimana diperlukan penggunaan tanah yang menyangkut kepemilikan masyarakat. Penetapan nilai pengganti wajar dalam pembebasan tanah untuk kepentingan umum di Kota Lhokseumawe dilakukan oleh tim appraisal dengan memperhatikan nilai fisik dan nilai non fisik sesuai dengan UU No 2 tathun 2012 dan Standar Penilaian Indonesia. Hambatan-hambatan dalam pelaksanaan pemberian ganti kerugian dalam pengadaan tanah untuk pembangunan rel kereta api Kota Lhokseumawe adalah hambatan yang berasal dari masyarakat pemegang hak atas tanah, bangunan dan tanaman serta benda-benda yang berkaitan dengan tanah adalah kurangnya kesadaran masyarakat untuk berperan serta dalam pembangunan dan kurang pemahaman terhadap arti kepentingan umum, fungsi sosial hak atas tanah, akibat kurangnya pemahaman mengenai rencana dan tujuan pembangunan proyek tersebut yang sebelumnya telah dilakukan penjelasan dan penyuluhan dari Panitia PengadaanTanah untuk pembangunan rel kereta api Kota Lhokseumawe.Masih ada saja masyarakat yang merasa kurang puas, terutama mengenai nilai pasar tanah, hal ini dikarenakan masyarakat beranggapan bahwa tanah mereka sama dengan tanah yang lain kenapa nilai pasar tanahnya berbeda.
