Evaluasi Pengaruh Getaran Kendaraan Truk dan Variasi Jarak terhadap Kerusakan Bangunan
Authors: Sunandar Asep , Mulyani Sri Yeni 
Published: October 2020

Getaran yang terjadi di jalan raya merupakan salah satu dampak yang disebabkan oleh kenaikan jumlah kendaraan berat dan kondisi jalan yang semakin memburuk, sehingga menyebabkan kerusakan bangunan yang ada di sekitar jalan (Osama Unaidi, 2008). Penelitian yang mengkaji hubungan antara kerusakan bangunan dengan intensitas getaran di jalan raya sudah banyak dilakukan, namun demikian kajian yang secara spesifik melihat hubungan intensitas getaran pada akses jalan menuju areal pabrik (gudang) belum banyak dilakukan.
Tujuan penelitian ini adalah mengetahui besarnya getaran yang dihasilkan oleh truk tronton dan dampaknya terhadap kerusakan bangunan. Untuk menjawab tujuan tersebut, metode penelitian yang digunakan adalah uji coba semi lapangan terhadap getaran yang bersumber dari truk tronton 30 ton yang divariasikan dengan jarak (50 cm dan 100 cm dari sumber getaran). Metode pengukuran mengacu pada INSTRUCTION MANUAL VIBRATION LEVEL METER, yang dihasilkan kemudian dievaluasi berdasarkan KEPMEN LH 49/MENLH/II/1996.
Penelitian menunjukkan bahwa getaran yang diukur pada jarak 50 cm masuk dalam katagori B, sedangkan pada jarak 100 cm masuk dalam katagori A. Berdasarkan KEPEMN LH 49/MENLH/II/1996, Katagori B (pada frekuensi alat 31,5 Hz) menunjukkan kemungkinan adanya keretakan atau terlepas plesteran pada dinding pemikul beban dan untuk katagori A (frekuensi alat 31,5 HZ) menunjukkan tidak adanya kerusakan pada bangunan. Kondisi ini bisa berubah apabila jumlah, beban dan kecepatan kendaraan yang terjadi lebih besar (seperti halnya di jalan arteri). Tingkat kerusakan bangunan yang ada akan berbeda, bahkan bisa jadi akan menimbulkan kerusakan yang lebih besar.

Abstrak- Kondisi pelayanan angkutan umum di Kota Padang sudah sangat memprihatinkan yang di dominasi oleh angkutan berkapasitas kecil yang menambah kepadatan dan kesemrawutan lalu lintas. Kondisi ini semakin diperparah oleh perilaku pengemudi yang ugal-ugalan karena berebut penumpang sehingga aspek kenyamanan dan keselamatan penumpang menjadi terabaikan. Di samping itu, Indonesia menggunakan bahan bakar minyak sebagai sumber utama energinya, yang sebagiannya adalah di impor. Fakta ini tentunya akan semakin memperburuk dampak negatif dari transportasi darat, termasuk di Kota Padang. Saat ini terdapat angkutan umum Bus Rapid (BRT) Transit Trans Padang yang sudah beroperasi sejak tahun 2014. Dalam rangka meminimalisir dampak negatif transportasi darat, maka direncanakan untuk mengembangkan koridor layanan Trans Padang dari semula 1 menjadi 6 Koridor. Untuk itu perlu di estimasi potensi demand nya, khususnya yang akan berpindah (mode shift) dari angkutan mobil penumpang umum (MPU) ke BRT Trans Padang yang merupakan tujuan dari penelitian ini. Luaran dari penelitian ini juga dapat digunakan sebagai pertimbangan sebagai informasi dalam penentuan prioritas koridor yang yang dikembangkan oleh stakeholder terkait.

In the implementation of construction projects there are often irregularities in costs caused by, among others, materials, equipment, labor, subcontractors, overhead, and general conditions. Material is a major cost component in construction projects, so that poor material management can lead to project cost deviations. The occurrence of cost deviations can be seen from the difference between implementation costs and planning costs. To minimize these cost deviations, project control is carried out aimed at detecting as early as possible the factors that affect the cost deviations, especially in material costs.
This study uses a questionnaire instrument involving 20 respondents consisting of contractors contracting M1 and M2 qualification buildings in Kota Padang, which are filled by site managers and logistics implementers. The analysis used is descriptive descriptive analysis with the help of the Statistical Product Solution Service (SPSS) program for Windows version 23.0.In this study, there are 6 sequences of dominant factors that influence material cost deviations on the final cost performance of the building project in Padang city.

Portfolio optimization for cointelated pairs: SDEs vs Machine learning
Authors: Mahdavi-Damghani Babak , Mustafayeva Konul , Buescu Cristin , Roberts Stephen 
Published: October 2020

With the recent rise of Machine Learning (ML) as a candidate to partially replace classic Financial Mathematics (FM) methodologies, we investigate the performances of both in solving the problem of dynamic portfolio optimization in continuous-time, finite-horizon setting for a portfolio of two assets that are intertwined. In the Financial Mathematics approach we model the asset prices not via the common approaches used in pairs trading such as a high correlation or cointegration, but with the cointelation model in Mahdavi-Damghani (2013) that aims to reconcile both short-term risk and long-term equilibrium. We maximize the overall P&L with Financial Mathematics approach that dynamically switches between a mean-variance optimal strategy and a power utility maximizing strategy. We use a stochastic control formulation of the problem of power utility maximization and solve numerically the resulting HJB equation with the Deep Galerkin method introduced in Sirignano and Spiliopoulos (2018) . We turn to Machine Learning for the same P&L maximization problem and use clustering analysis to devise bands, combined with in-band optimization. Although this approach is model agnostic, results obtained with data simulated from the same cointelation model gives a slight competitive advantage to the ML over the FM methodology 1 .
