Metode permukaan respon merupakan sekumpulan teknik statistika yang berguna untuk menganalisa permasalahan dimana beberapa variabel bebas mempengaruhi variabel respon dan tujuan akhirnya adalah untuk mengoptimalkan variabel respon. Metode ini pertama kali diajukan pada tahun 1951 oleh Box dan Wilson. Penerapan metode permukaan respon yang digunakan untuk optimalisasi proses sealing pada pengemasan produk makanan jelly merk Big Stick menunjukkan bahwa faktor-faktor yang berpengaruh terhadap presentase produk nonBS adalah lamanya waktu pressing kemasan dan suhu yang digunakan pada proses sealing. Nilai respon presentase produk nonBS optimum diperoleh pada waktu detik dan suhu . Sedangkan nilai respon presentase produk nonBS optimal diperoleh sebesar . Titik optimum pada permukaan respon merupakan titik pelana, karena nilai eigen dari matriks yang diperoleh berlainan tanda (positif dan negatif) yaitu dengan nilai dan . Keywords: Metode permukaan respon, desain eksperimen, regresi linier, analisis varian.

The function of the foundation as a substructure that transmits the load received from the upper structure of the building into the foundation makes the foundation have an important role. The strength of the foundation is something that needs to be planned properly. This planning aims to plan the foundation for the Permata Indah Building, Nganjuk Regency, which will later be used as a boarding house building. Planning that is carried out includes selecting the type of foundation, calculation of dimensions, and foundation reinforcement. Based on soil investigation results, the foundation type pile was chosen because the hard soil was located at a depth of 17 m. The method used to calculate the bearing capacity of the pile includes the Meyerhoff, Begemann, and Trofimankove methods. With a diameter of 30 cm and 4 poles, the carrying capacity of group piles (Pg) was obtained using the Meyerhoff method of 224.60 tons, the Begemann Method of 199.59, and the Trophimankove Method of 259.36 tons. From these results, the group pile bearing capacity value is still greater than the value of ƩVu= 146.28 tonnes. Meanwhile, for a single pile settlement Se= 2.13cm <Sijin= 3 cm SAFE and a pile settlement group Sg= 3.98cm.

Simpang empat di simpang Jl. Bendo – Pogalan Di Kabupaten Trenggalek merupakan salah satu persimpangan di Kabupaten Trenggalek, kawasan ini merupakan titik pertemuan kendaraan dari luar daerah untuk menuju kawasan komersial. Oleh karena itu, lalu lintas di ruas ini tinggi, sehingga mengakibatkan kemacetan dan tundaan kendaraan yang lama, terutama pada jam sibuk. Penelitian ini untuk mengetahui kinerja simpang bersinyal, serta mencari alternatif lalu lintas untuk mengatasi permasalahan kemacetan. Metode yang digunakan berdasarkan MKJI 1997. Berdasarkan hasil penelitian, panjang antrian dan derajat kejenuhan pada simpang ini cukup tinggi, beberapa alternatif dilakukan untuk mengatasi permasalahan tersebut. Alternatif II dianggap paling optimal dengan mengurangi fase sinyal, sehingga mengurangi derajat kejenuhan (DS). Berdasarkan hasil analisis perubahan fasa didapatkan bahwa derajat kejenuhan dari semua arah pendekatan mengalami penurunan dan peningkatan. Untuk tundaan simpang rata-rata sebesar 46,36 detik/smp. Maka alternatif yang tepat saat ini adalah dengan mengurangi fasa sinyal.

The slums in Sidoarjo city are caused by people who ignore the cleanliness of the environment. The number of people who dispose of waste, household waste, or production waste in the channel causes the reduced function of drainage channels. This study aims to determine the capacity of existing channels in the flood area of Sidokare and Lemahputro slum, Sidoarjo. The method used uses a quantitative descriptive method—hydrological data obtained from rainfall recording stations for ten years. The data was then analyzed using rational methods to calculate the discharge of flood plans when resetting the 10-yearly. The hydrology and hydraulic analysis calculation results obtained plan discharge (Qr) of 0.092 m3/s and existing discharge (Qs) of 0.032 m3/s. These results showed the existing channel condition could not accommodate the discharge of rainwater runoff, so there needs to be redimence of the channel. From the analysis of the dimensions of drainage channels conducted, obtained a new channel in the form of Box U-Ditch with a channel depth (h) 0.50 width under the channel (b) 0.40 m, with channel discharge plan that 0.128 m3/s can accommodate.

In a construction project, there are several aspects that cause the project not to go according to plan. Cost and time are aspects that need to be considered to avoid losses incurred in a project. Jombang-ploso-legundi-gresik road project is one of the road widening projects carried out by PT. Mix Pro Indonesia. The project was carried out with the aim that access to (Surabaya-Mojokerto) or further trans Java toll road is quicker safe and smoother. This research aims to optimize the cost and time on the project using the Earned Value method. Calculations include the calculation of ACWP (Actual Cost of Work Performance), BCWS (Budgeted Cost Work Schedule), and BCWP (Budgeted Cost for Work Performed) using the Earned Value method. From these parameters, estimate aspects of cost and time. As well as project analysis of acceleration on a critical trajectory of work. The results of calculations in the 12th week obtained a BCWS value of Rp 1,216,677,846,400 BCWP = Rp 3,040,372,140,080, ACWP = Rp 3,678,560,000. CV value = -Rp 109,203,495.92, SV = Rp 895,646,816.82, CPI = 0.827, and for SPI = 2,499. From these results it can be seen that the CPI value < 1 which means that there are project expenditures that exceed the original plan. With the results, it can be used as a reference in the implementation of project activities.

Construction management is very necessary in project management. To increase the efficiency and effectiveness of construction development activities, a unit price calculation tool is needed, namely construction cost analysis. Contractors generally make bid prices based on analysis that is not entirely guided by BOW (Burgerlijke Openbare Werken) analysis or SNI (Standart National Indonesia) analysis. Contractors tend to calculate the unit price of work using their own analysis which is based on previous experience in completing a construction work. The purpose of this study was to analyze the unit price of work on the building using the SNI, BOW and Field methods. The work components analyzed in this study are the unit price of materials and wages for partner work and foundation work. In each calculation method used, the most economical cost budget plan is obtained, namely using the field method calculation with the unit price value for the work of a partner, it costs Rp. 509.9996.78 while for foundation work it costs Rp. 722,965.1. By using the field method, a unit price is more economical when compared to BOW and SNI methods. So that these results can be used as a reference in planning the budget for a construction project.
