Abstract

    A structural system determines the strength of the building in order to be able to survive in the long period of time. Functioning as residential house, Bugis houses have been through a long period of time and are supported by the use of specific structural system of the building. This structural system has changed in many ways and forms. This research is aimed at identifying the changes that have occurred in the structural system of old Bugis houses and factors that influence such changes. This research employed descriptive models and typology. Descriptive models were used to reveal the phenomenon of point movement of the structural system aided by SAP 2000 software. Typology was used to classify the types of changes that occurred in the system. The research revealed that the structural system of building of Bugis houses has changed by means of cross and internal system. The system used in the past had lower strength than that used in the next period. The characteristics of the changes in the structural system improved by means of transfer of the use of the construction method from the use of free placement to the use of stiff connection. This change was influenced by three aspects, namely of natural resource aspect, stiffness aspect, and cultural and belief aspects. The natural resource aspect is related to the availability of building materials in terms of quality and quantity. The building of Bugis houses in the past used higher quality materials than the system that developed afterwards. The stiffness is related to the efforts of Bugis technocrats in the past in optimizing the structural system. The results of the analysis indicated that the extent of the horizontal of a point movement is in proportion to the height of point position of the structural system. The higher the location, the greater the movement. The culture and belief are related to the survival for individual and group.Keywords: changes, structural system, Bugis houses

Abstract

ABSTRACT Indonesia is an area with high earthquake risk, where earthquake-resistant design is required, in critical category IV buildings such as hospitals and educational buildings must be designed to remain operation during and after the earthquake design, without significant damage. owners have the ability to establish and know the performance levels of structures designed with performance-based design methods that impact on development costs, repair costs and reduce casualties due to earthquakes. there are two performance based design methods namely pushover and nonlinear history of time (NLTHA). with ductility values of μ 3 or R 4.8 and Ie 1.5, the structures are designed to have an opertional (O) performance during the earthquake design (DBE) and immediate occupancy (IO) during a maximum earthquake (MCE). using acceptance according to the capacity spectrum method, element acceptance limit and drift according to FEMA 356.Keyword: operational, ductility, performance based design ABSTRAK Indonesia merupakan daerah dengan resiko gempa tinggi, dimana dibutuhkan perencanaan tahan gempa, pada bangunan penting kategori IV  seperti rumah sakit dan gedung pendidikan harus didesain  tetap beroperasi saat dan setelah terjadinya gempa rencana, tanpa mengalami kerusakan yang signifikan. Pemilik memiliki kemampuan untuk menetapkan dan mengetahui level kinerja dari struktur yang didesain dengan metode performance based design yang berdampak pada biaya pembangunan, biaya perbaikan dan mengurangi korban jiwa akibat gempa. Dimana terdapat dua metode performance based design yaitu pushover dan nonlinier riwayat waktu (NLTHA). Dari penggunaan nilai daktilitas sebesar μ 3 atau R 4.8 dan Ie 1.5, struktur yang didesain memiliki kinerja opertional (O) saat terjadinya gempa rencana (DBE) dan immediate occupancy (IO) saat terjadi gempa besar (MCE). Dengan menggunakan penerimaan menurut capacity spectrum method, batas penerimaan elemen dan drift menurut FEMA 356. Kata Kunci: operasional, ductility, performance based design

Abstract

The city of Magelang is having trouble providing Final Disposal Sites (TPA), as the Banyuurip TPA's storage capacity has reached its limit and expansion is no longer possible. The only approach to reduce garbage production and residue transferred to landfills is to engage the community and all other stakeholders in waste management. This program intends to develop a waste management strategy in Magelang City starting with the smallest units, namely RT and RW. According to the findings, waste management solutions for the community of RW 02, Magelang Village, Central Magelang District may be classified as socialization strategies, work plans or regulations, resource procurement, cooperation, and empowerment. Furthermore, the study's findings reveal that an effective strategy must include multiple activities that operate concurrently, progressively, and sustainably, as well as the participation of various parties (community, local government, and universities) in assuring effective management implementation.

Abstract

Abstract Tanah Miring–Kurik Road, Merauke is one of the national roads in Merauke Regency which has been reconstructed into composite pavement. Composite pavement is a combination of flexible pavement and rigid pavement. This study aims to determine the response of composite pavement structures due to vehicle loading and the effect of temperature on pavement. The response analysis of road pavement structures was carried out using the finite element method, using the SAP 2000 computer program. Pavements are idealized in 2 analysis models, namely the slab model on elastic foundations and the 3D Solid model. From the results of the analysis on the plate model on an elastic foundation, the maximum tensile stress that occurs in the concrete slab is 2.081 MPa at 6% subgrade CBR. The maximum tensile stress produced by the 3 Dimensional Solid model is 2.510 MPa. The pavement can withstand stresses due to the combined effects of temperature and vehicle loading up to a temperature gradient of 6°C on the subgrade CBR of 6%. The Hot Rolled Sheet layer can reduce the maximum tensile stress in concrete slabs by up to 9.7%, for slab models on elastic foundations, and 9%, for 3 Dimensional Solid models. Keywords: composite pavement; road pavement; pavement structure response; finite element method. Abstrak Jalan Tanah Miring–Kurik, Merauke adalah salah satu jalan nasional di Kabupaten Merauke yang telah direkonstruksi menjadi perkerasan komposit. Perkerasan komposit merupakan kombinasi antara perkersan lentur dan perkerasan kaku. Penelitian ini bertujuan untuk mengetahui respons struktur perkerasan komposit akibat pembebanan kendaraan dan pengaruh temperatur pada perkerasan. Analisis respons struktur perkerasan jalan dilakukan dengan menggunakan metode elemen hingga, dengan memanfaatkan program komputer SAP 2000. Perkerasan diidealisasikan dalam 2 model analisis, yaitu model pelat pada fondasi elastis dan model Solid 3 Dimensi. Dari hasil analisis pada model pelat pada fondasi elastis, diperoleh tegangan tarik maksimum yang terjadi pada slab beton adalah 2,081 MPa pada CBR tanah dasar 6%. Tegangan tarik maksimum yang dihasilkan model Solid 3 Dimensi sebesar 2,510 MPa. Perkerasan dapat menahan tegangan akibat pengaruh kombinasi temperatur dan pembebanan kendaraan hingga pada gradien temperatur permukaan dan dasar perkerasan sebesar 6°C pada CBR tanah dasar 6%. Lapisan Hot Rolled Sheet dapat mengurangi tegangan tarik maksimal pada pelat beton hingga 9,7%, pada model pelat pada fondasi elastis, dan 9%, untuk model Solid 3 Dimensi.
