Kriteria-Kriteria Pemancangan yang Mempengaruhi Pengambilan Keputusan pada Pemilihan Jenis Driven Pile dan Metode Pemancangan

Abstract

Pengambilan keputusan membuat praktisi berhadapan dengan berbagai kondisi yang mempengaruhi pemilihan jenis tiang dan metode pemancangan. Penelitian ini bertujuan untuk mengkaji kriteria-kriteria pemancangan yang mempengaruhi pemilihan jenis driven pile dan metode pemancangan yang optimal. Konseptual model disajikan sebagai model teoritis dari literature review yang dilakukan. Survei pendahuluan dilaksanakan dengan mengidentifikasi kriteria dengan wawancara kepada empat expert yang berpengalaman melakukan pekerjaan pemancangan pondasi. Kriteria yang telah diidentifikasi oleh expert digunakan untuk survei kuesioner. Survei kuesioner dilakukan kepada 45 responden praktisi yang pernah melakukan pekerjaan pemancangan pondasi di Balikpapan. Analisis yang digunakan untuk mengetahui kriteria yang berpengaruh adalah analisis deskriptif, uji nonparametrik (Kruskal-Wallis), uji validitas dan reliabilitas. Hasil mendapatkan tiga variabel utama yang meliputi kriteria pemancangan, jenis driven pile dan metode pemancangan. Enam kriteria pemancangan penentu yang didapatkan yaitu karakteristik tanah, kondisi lapangan, karakteristik bangunan, biaya, waktu dan pengalaman sebelumnya.

Variations of Washing Agent on The Physicochemical And Microbiology Properties of Sago Starch

“…The analysis of sago starch includes physical characteristics (shape, aroma, color, taste), chemical characteristics (moisture content, ash content, crude fiber, starch, acid level, SO2 content, metal content), and microbiological characteristics [15]. The experimental design used was a factorial completely randomized design with three factors, and each treatment had three replications [16]. The best treatment is determined on all parameters with weights according to the level of importance [16].…”

“…The characteristics weight of the sago starch washing treatment can be seen in table 7. After weighting the quality and cost of washing sago starch, it was continued with an assessment of the physical, chemical, microbiological, and cost according to the research results [16]. The value of quality characteristics and the cost of washing sago starch is presented in Table 8.…”
