MENCEGAH KONFLIK SOSIAL DALAM PEMBANGUNAN INFRASTRUKTUR BERKELANJUTAN
No full textKonflik sosial dalam pembangunan infrastruktur berkelanjutan harus dihindari. Konflik yang berkelanjutan yang berawal dari pro dan kontra teknologi akan mengakibatkan social cost yang amat luar biasa tinggi. Persatuan Insinyur Indonesia dalam etika profesi menyebutkan bahwa insinyur senantiasa menghindari terjadinya pertentangan kepentingan dalam tanggung jawab tugasnya. Hal ini berarti bahwa insinyur senantiasa menghindari konflik kepentingan atau pro dan kontra pemilihan suatu teknologi yang akan dibangun. Elemen konflik meliputi : Pemicu yang dianalogkan dengan api; akselerator yang dianalogkan dengan angin panas; dan akar konflik yang dianalogkan dengan rumput kering. Umumnya, terdapat lima tahap eskalasi konflik yaitu: Sengketa, Ketegangan/mobilisasi, Krisis, Kekerasan terbatas, Kekerasan massal, dan Penurunan eskalasi konflik. Semua hal diatas tidak akan terjadi lebih kelam, apabila melalui proses kajian kelayakan, perencanaan yang jelas dan berkaitan dengan etika, moral, aturan, budaya, dan kepentingan sosial. Eskalasi konflik dilawankan dengan deeskalasi konflik yaitu konflik dilawankan dengan pembangunan damai yang pada akhirnya akan sampai kepada pemilihan teknologi tepat guna yang memberi rasa damai kepada masyarakat luas. Rumusan masalah studi ini adalah bagaimana tren konflik yang terjadi dan bagaimana cara menyikapi pro-kontra rencana pembangunan infrastruktur. Tujuan tulisan adalah mengungkap tren konflik yang terjadi, mengedepankan nilai budaya, mengedepankan posisi sebagai analis dan mengedepankan tatanilai etika dan moral dalam pembangunan infrastruktur berkelanjutan. Metodologi yang dipakai adalah mengamati jalannya suatu pro dan kontra, menganalisis data sekunder hasil kajian infrastruktur. Beberapa kasus yang dibahas antara lain Studi kelayakan Jalan Tohpati Kusamba, Jalan Sunset, reklamasi Teluk Benoa, Taman nasional Tesso Nilo, Kerinci Seblat, Kayan Mentarang, Kutai dan Sebangau. Simpulan dan saran dari kajian ini adalah bahwa nilai Sosial Budaya melalui fokus group discussion harus dikedepankan dan menjadi faktor penentu, disamping kelayakan secara Hukum, Lingkungan, Teknis, dan Ekonomi sesuai dengan prasyarat suatu kajian infrastruktur berkelanjuta
Effectiveness of vertical drains in soft clay with special reference to smear effect
No full textThis thesis includes mathematical simulation of smear effects in a 2-D plane strain finite element model employing the modified Cam-clay theory, and the experimental evaluation of smear zone propagation around vertical drains using a large scale, radial drainage consolidometer. The original axisymmetric analysis of vertical drains including the effect of smear and well resistance has been well documented in the past. In contrast, in this study, the analysis of a unit cell is conducted by converting the axisymmetric (radial) permeability into an equivalent plane strain model Thereafter, a multi-drain, plane strain analysis is conducted to study the performance of the entire embankment stabilised with vertical drains, for number of case histories taken from Southeast Asia. laboratory technique of evaluating the extent of smear around vertical drains is elaborated. In this approach, a central vertical drain was installed in soil specimens placed in a large steel cell (450 mm in diameter and 950 mm in height), using a specially designed mandrel. Once the drain was installed, smaller specimens were recovered from various radial distances from the drain, and the horizontal and vertical permeabilities of these specimens were determined by standard oedometer tests. The extent of the smear zone was established as a function of the horizontal and vertical permeability ratio (kh/kv). It was found that the ktJh ratio decreased significantly towards the central drain. It is also revealed that the krfkv ratio approaches unity soil drain interface, and is about 1.3 at the undisturbed region outside the smear zone. Axial and radial permeabilities were converted to 2-D plane strain parameters based on the mathematical model developed in this study. The mathematical model was used in conjunction with finite element analysis (CRISP) to determine the settlements, lateral movements and pore pressures. selected case histories include a number of embankments stabilised with vertical drains in Thailand, Malaysia and Indonesia. The embankments were well instrumented with settlement gauges, piezometers and inclinometers. The settlements, excess pore pressures and lateral displacements were predicted using the plane strain, multi-drain model, and the results were compared with the fields measurements. The effect of smear was found to be significant in controlling the performance of vertical drains, while the role of well resistance was found to be insignificant. The model described in this thesis provides an excellent plane strain formulation capable of predicting the behaviour of embankments constructed on soft clay foundations stabilised with vertical drains

Aquifers selection based on geoelectric method data in the framework of drilling wells: A case study on international hospital project in Nyitdah Tabanan Bali
No full textThe selection of aquifers based on Geoelectric Method data in constructing drilling wells was discussed in the present study. The research was conducted at the International Hospital Project in Nyitdah Tabanan Bali. The research position was around 8,5736 LS 115,1215 LE. Before the study was conducted, a well drill (well 1) has been made. The results showed that there were two types of aquifers, namely unconfined aquifers and unconfined aquifers. Related to this study, well 1 took water in the unconfined aquifers of 4 m depth. If the water kept taken for a long period, the quality and quantity of the water would be worse since well 1 was unconfined aquifers that took surface water. This would adversely affect the hospital building being built. The land around the building would be hollow due to the water loss, and the building would become unstable. Another drill well (well 2), based on geoelectricity data, can be made on 5,25 m - 18,75 m. In-depth 23 m, it was suspected that unconfined aquifers would have been found in well 2. After being drilled, aquifers were found in 23 m depth. Drilling was kept doing to 55 m depth

ANALISIS DINAMIS DINDING PENAHAN TANAH AKIBAT BEBAN DINAMIS
No full textIn general, the failure of retaining wall construction is influenced by the geometry
of the construction of retaining wall, physical and mechanical properties of the soil
embankment and/or subgrade and static and/or dynamic load. In a dynamic analysis of
the stability of retaining wall, landslide surface behind the retaining wall are calculated
based on assumptions. It is required to develop a method that is appropriate in site
planning construction of retaining wall due to the dynamic loads by considering the
form of sliding soil behind retaining wall. The results of this study are expected to
determine the role of these parameters to the movement of the material behind the wall
due to the sinusoidal dynamic load. This research used the movement of materials with
equivalent static analysis to analyze the stability of the retaining wall.
This study was conducted to the small-scale test of a retaining wall model in the
laboratory. This models used gravity of retaining wall, which was made of concrete and
was placed on dry sand with a trapezoid-shaped a height of 20 centimeters, width of
peak 2 centimeters and width of below 10 centimeters and cantilever with a height of
18.3 centimeters, width of 9.3 centimeters that is placed on dry sand that can pass
through sieve No. 4 and retained on sieve No.100. Variations in the relative density of
the sand used for testing is a relative density (DR) of sand of 30%, DR of 60% and DR
of 75% to model gravity and DR of 30%, DR of 55% and DR of 70% for the cantilever
model. The model placed in the glass box of a length of 2 meters, width of 0.4 meters
and height of 1 meter. The model vibrated using a shaking table that is moved
horizontally with variation of the vibration frequency (f) and the amplitude of vibration
(A). Sinusoidal dynamic acceleration response is recorded using an accelerometer.
Granular soil displacement at some point also be monitored during the test.
The results showed that the shape of the field of material movement behind the
retaining wall is influenced by DR of sand, type of retaining wall and the sinusoidal
dynamic acceleration (a
maks
). The DR of sand effect on the area and shape of material
movement field by certain a
maks
. The lower of affect DR then the wider and deeper the
field of material movement. The relationship of a
maks
against the width of material
movement and a
maks
against the height of material movement is linear. The parameter of
f is more dominant influence on the a
maks
compared with A. The percentage of increase
in a
maks
be two-fold when the f be improved. If the A is increased then the increase of
a
maks
be proportional to the increase in A. The parameter of f has a dominant effect on
the height of the material movement field. The greater of f then the greater of height of
material movement field. The parameter of A has a dominant influence on the width of
the material movement field. The larger of A getting wider the field of material
movement that occurred. By delivering three variations a
maks
of 0,221g, 0,245g and
0,27g the safety factor of overturning (SF
overturning
) for both models showed a decrease
due to increased of the material movement bandwidth, as a result of the increase in the
a
maks
. By increasing the DR, then the SF
overturning
decreases follow the trend of their
respective functions. the SF
sliding
for two types of models show a decline, along with the
increase of vast of material movement field. The safety factor of sliding (SF
sliding
)
increases follow the trend of their respective functions if the DR increased.
