Abstract

The slope is a surface that lies at an angle to the horizontal. If the driving force at the slope is bigger than the resisting force, it can inflict a landslide. Gabions are one of the slope reinforcements structures that can be used to prevent landslides. Gabion has woven wire and has tensile strength.  This study aims to examine the effect of modeling of tensile strength on gabion wire using Plaxis 3D, as well as the effectiveness of variations in height, variations in tensile strength, variations in gabion reinforcement patterns on slopes. The soil is modeled as homogeneous loamy sand with a geometry of 10m high and 1:1 slope. Modeling the tensile strength of gabions can increase the value of the safety factor by 9.5% compared to without modeling the tensile strength of gabions. The optimal gabion height that increasing the safety factor is 6m. The value of the tensile strength of gabion wire does not have a significant effect on the safety factor of the slope. The placement of gabions with a zigzag and lined pattern and a gentle slope will more increase the safety factor.

Abstract

Using Portland pozzolan cement (PPC) is considered suitable for infrastructure in the sea area because it has a high resistance to salt and sulfate but still produces carbon dioxide gas emissions that can damage the environment. Environmentally friendly materials that can completely replace cement are geopolymer materials. This study compared the mechanical properties of PPC mortar and geopolymer mortar with and without white soil under seawater bath conditions. The test object is a 5x5x5 cm mortar cube with fly ash, white soil, sand, water, alkaline activator NaOH 8M, and PPC cement. Mortar variations include PPC mortar, geopolymer mortar without white soil substitution (TTP), and 15% white soil substitution mortar (TP15%). Tests include compressive strength, tensile strength, porosity, density, and absorption for all three variations. Microstructure testing of the influence of the bath is carried out on the TP15% mortar. The test results showed that PPC mortar has better resistance compared to both variations of geopolymer mortar in terms of its compressive and tensile strength at a bath life of 28 days, namely 32,427 MPa and 2,318 MPa, while the geopolymer mortar produced maximum compressive and tensile strength values of 14,373 MPa and 0.993 MPa. TTP mortar has better resistance than TP15% mortar. Microstructure testing showed mortar with baths had a denser matrix.

Abstract

A traveler will consider many things in choosing a mode because the availability of transportation modes is variated. The traveler's characteristics, the trip's characteristics, and the facilities of transportation mode characteristics can influence a person's decision in choosing a mode. The study of the selection of modes of transportation to campus by students, lecturers, and other workers at the Faculty of Economics and Business, State University of Malang, aims to describe the characteristics of mode users and determine the mode selection models to go to campus. This study used a descriptive analysis method to determine the characteristics of mode users and the binomial difference logit method for modeling transportation. The results of the study showed that five factors are most influential in choosing a mode between private transportation and public transportation at the Faculty of Economics and Business, the State University of Malang, namely ownership of a driving license, travel distance, the comfort of transportation, the safety of transportation, and availability of transportation which produces a regression model UKP – KU = -11.480 + 4.045 (X7) – 1.263 (X8) + 5.102 (X11) + 2.302 (X12) + 5.693 (X14). This model has an R2 value of 0.743 and a classification plot of 0.927. From the results of the modeling equation, the probability value of mode selection for private transportation is 0.997. In contrast, public transportation gets a probability value of 0.003.

Abstract

The purpose of this research is to design the utilization of the potential of Kulong Kebintik, in the form of the potential of Kulong water and the land around Kulong. The method used is a quantitative descriptive survey method. Most of the data used is in the form of secondary data, the primary data is only in the form of kulong water quality data. Quantitative Kulong Kebintik water is based on analysis using the Nreca model. has a monthly average debit of 114.7 liters/second. In terms of water quality, Kulong Kebintik is brackish because it is located close to the coast which is still affected by tides. Kulong water utilization analysis uses the Analytical Hierarchy Process (AHP) method. The basis for determining alternative designs for the use of kulong consists of four criteria in the form of; water availability, water quality, community demand, and cost. An alternative utilization of kulong is for raw water sources, tourism, and fisheries. Based on an analysis of all the criteria, the best Kulong utilization design is for fisheries (39%), then for tourism or recreation (32%), and finally for raw water sources (29%)

Abstract

One of the obstacles to construction work in Papua is delays in implementation due to obstruction byindigenous communities at the project site. Understanding the implementation of construction work in atraditional area, especially those related to local wisdom, is one of the risk knowledge which is the first step inrisk conceptualization and is the aim of this research. A qualitative approach, which will elaborate on socialand cultural meanings to explain one of the phenomena that occurs in the world of construction in Papua, anddescriptive methods, are used in analyzing research data. The characteristics of the traditional territory wherethe project location is located also influence the construction risk value of a project. Based on the topographiccharacteristics of the region, there are four large groups of Papuan indigenous people, so there are differencesin the construction risk values faced according to the socio-cultural characteristics of each traditionalcommunity. Urban areas have a high construction risk and rural areas have a lower risk. The risk value ofconstruction projects in Papua is also influenced by the type of construction project which will be related tothe required land pattern.

Abstract

Surabaya merupakan kawasan pesisir yang diproyeksikan sebagai kawasan strategis untuk perkembangan berkelanjutan wilayah pesisir sesuai rencana pembangunan jangka menengah daerah kota Surabaya 2016-2021. Kawasan strategis wilayah pesisir yang berfungsi sebagai pendukung pertumbuhan ekonomi, dan penyelamatan lingkungan hidup sebagai upaya optimalisasi pembangunan kawasan pesisir, sehingga diperlukan studi untuk mengetahui pengembangan wilayah tersebut. Studi ini dilakukan untuk mengetahui kekuatan, kelemahan, peluang dan ancaman pada wilayah pesisir Surabaya. Peneliti melakukan pendekatan kualitatif pada analisis dan bersifat study case yang diperlukan. Analisis pada kegiatan ini menggunakan metode SWOT. Hasil Analisis SWOT adalah hasil perbandingan faktor internal dan eksternal, analisis dilakukan dengan matriks IFAS (Internal Factor Analysis Summary) dan matriks EFAS (Eksternal Factor Analysis Summary). Berdasarkan analisa SWOT dapat ditunjukkan bahwa pengelolaan wilayah pesisir Kota Surabaya sesuai dengan rencana tata ruang yang sudah dibuat, namun dalam realisasi harus memperhatikan komunikasi dan sosialisasi kepada masyarakat yang dinilai belum optimal, serta penanggulangan dampak dan perawatan lingkungan secara berkala sehingga ancaman pesisir dapat diminimalkan..
