Abstract

Initial damage to the structure occurs in the outer layers of the affected surface exposure to the peat environment and the static and dynamic movement of the structure. To prevent structural damage, the latest technological innovations are needed in the use of mortar constituent materials to increase the strength of the mortar. Polymer mortar is a composite material formed from a mixture of fine aggregates, cement, water and polymer binders or binders with a certain level. The purpose of this study is to determine the effect of the use of acrylic binders on the physical and mechanical properties of polymer mortars and the influence of peat water on the future of the mortar. The substitution of acrylic binders with water consists of 3 substitutions, namely 20%, 30% and 40% and 0% as controls. The results of the search for acrylic binders on the mortar mixture obtained a minimum physical property value at 30% acrylic use in the 28-day test, namely. The porosity value of the mortar is 9.80%, the waterabsorption value of the mortar is 4.67% and 4.72%, and the sorptivity value of the mortar is 0.70. From the value of physical properties obtained the degree of tightness of the polymer mortar well with the use of acrylic binders in the mixture. For the mechanical properties of polymer mortar, compressive strength testing is carried out with optimum compressive strength at the use of 30% acrylic. The value of the compressive strength of the mortar is 33 Mpa.

Abstract

Peat beaches are beaches whose land can be easily abraded than beaches with other types of land. This is due to the light density of peat soil so that it can be easily carried away by the flow of sea water. One of the peat beaches in Indonesia whose coastline has changed significantly in recent decades is the peat beach on Bengkalis Island, Riau Province. Peat samples were taken from Tanjung Jati Beach, Perapat Tunggal Village, Bantan District, Bengkalis Island, Bengkalis Regency, Riau Province and then the sample is carried out an initial motion analysis on peat soil sediment transport. The peat sample that is obtained is a type of fibric peat soil. This research is a basic research that aims to determine at what speed the peat soil begins to move by the flow of water so that it can be seen the relationship between flow velocity and particle diameter at the beginning of the particle movement. The analysis was carried out by visual observation during simulation in the laboratory using a modified flume which was then compared with the results of Shields' theoretical calculations. Simulations were also carried out using sand sediment as a comparison. The flume flow velocity is determined from 0.00989 m/s to 0.10112 m/s for peat material, and 0.03973 m/s to 0.18900 m/s for sand material. The velocity is considered to have met the required simulation conditions, starting from the sediment not moving, starting to move, and being carried away by the flow. The results of the analysis carried out show that the peat material begins to move at a lower speed than the sand material. This is due to the specific gravity of the peat material being lighter than the specific gravity of the sand material as a comparison. This research is also expected to be a reference for further research on related topics. Keywords : Peat, Flow Velocity, Initial Particle Motion, Critical Shear Stress, Shields Theory

Abstract

Perilaku bangunan selama gempa bumi sangat berpengaruh terhadap bentuk, ukuran dan geometri bangunan. Bangunan tinggi dengan aspek rasio vertikal yang besar berpengaruh terhadap respon struktur ketika menahan gaya lateral. Tujuan dari penelitian ini adalah menganalisis respon struktur dengan gempa rencana terhadap aspek rasio vertikal maka akan memodelkan struktur beton bertulang sebanyak 6 model bangunan yang memiliki aspek rasio vertikal yang berbeda dan dilakukan dengan metode analisis linier. Penelitian ini mengkaji karakter dinamik struktur berupa periode, terhadap beban gempa berupa gaya geser dasar, dan perpindahan struktur. Hasil periode modal getar struktur menunjukkan periode struktur semakin besar dan melebihi periode maksimum berdasarkan SNI 1726-2019, terlihat pada pemodelan 1 hasil periode struktur sebesar 1.24 dan melebihi periode maksimum yakni 1.17. Hasil penelitian menunjukkan bahwa gaya geser dasar tidak memberikan dampak berupa kenaikan gaya pada setiap aspek rasio, hal ini dikarenakan periode struktur yang besar sehingga percepatan gempa yang terjadi tidak dalam range gempa maksimum. Hasil penelitian menunjukkan bahwa momen guling memberikan dampak berupa kenaikan pada setiap aspek rasio, hal ini berpengaruh terhadap massa struktur yang bertambah begitu juga perpindahan yang semakin besar sehingga momen yang dihasilkan juga semakin besar. Pertambahan tinggi struktur berdampak pada perpindahan yang semakin besar karena kekakuan struktur yang semakin rendah sehingga ketika menerima gaya lateral, struktur yang lebih tinggi mengalami ayunan yang lebih besar, nilai perpindahan paling besar terjadi pada aspek rasio 4.7 yakni sebesar 135.8 mm. Simpangan antar-tingkat bangunan relatif lebih besar terjadi pada aspek rasio 4.7 pada lantai 3 sebesar 1.51 %, namun masih dalam kondisi elastis dan memenuhi syarat batas izin sebesar 2.5% berdasarkan SNI 1726-2019. Parameter seismik kritis sangat berpengaruh terhadap aspek rasio vertikal bangunan karena sifat bangunan semakin tinggi yang ramping dan fleksibel akan memberikan respon yang relatif besar ketika terjadi gaya gempa.

Abstract

Kegiatan proyek pembangunan adalah suatu kegiatan yang jadwal mulai dan selesai sudah ditentukan, dengan alokasi sumber daya tertentu dan dimaksud untuk menghasilkan suatu produk. Apabila terjadi keterlambatan jadwal maka mempengaruhi tujuan dari proyek. Terjadi keterlambatan pada Proyek Pembangunan Gedung Utama Makorem antara jadwal rencana dan realisasi pelaksanaan. Adapun deviasi dari kurva S rencana dengan kurva S realisasi sebesar 22%. Menurut Yiu, et.al, (2018); Sandyavitri, (2019) risiko diklasifikasikan pada risiko tinggi (high-risk) apabila deviasi antara skedul rencana dengan realisasi memiliki keterlambatan >20%. Sehingga perlu dilakukan analisis risiko pada tahapan konstruksi. Pada penelitian ini menggunakan software Primavera P6 untuk menentukan jalur kritis kegiatan dan metode Relative Importance Index (RII) untuk menentukan faktor signifikan penyebab keterlambatan pelaksanaan proyek. Pada proyek ini terjadi keterlambatan selama 14 hari sehingga di identifikasi faktor keterlambatan dari 48 faktor keterlambatan tervalidasi menjadi 12 faktor keterlambatan. jalur lintasan kritis terjadi pada pekerjaan persiapan, pekerjaan pondasi, pekerjaan beton, dan pekerjaan arsitektur. 5 peringkat teratas adalah 1) Kerusakan material (RII sebesar 0,65), 2) Perubahan desain oleh owner dan tim selama konstruksi (RII sebesar 0,62), 3) Mobilisasi peralatan yang lambat (RII sebesar 0,62), 4) Kurangnya pengalaman konsultan dalam proyek konstruksi (RII sebesar 0,57), 5) Pergantian subkontraktor (RII sebesar 0,55).
