Abstract

Abstrak Konstruksi non struktural rentan rusak akibat beban impact. Salah satu upaya menanganinya dengan menggunakan ferosemen yang mampu memberikan daya tahan kejut dengan baik. Matriks ferosemen dapat berinovasi menggunakan beton ringan yang telah banyak digunakan, salah satunya memakai busa yang dinamakan menjadi ferrofoam concrete. Tujuan penelitian ini mengamati kapasitas beban impact terhadap ferrofoam concrete dengan pasir pozolan dan tanpa pasir pozolan sehingga dapat digunakan pada konstruksi dengan tingkat ketahanan kejut yang besar. Sebanyak 4 benda uji pelat memiliki dimensi penampang 400 mm dengan ketebalan 40 mm digunakan dan 4 lapis wiremesh ditetapkan. Perbedaan SG 1200 kg/m³, 1400 kg/m³ dan 1600 kg/m³ menjadi pertimbangan dengan FAS 0.4 dan penambahan 10% pasir pozolan ditentukan. Pengujian beban impact diaplikasikan terhadap pelat dengan menjatuhkan bola besi sebesar 3 kg dari ketinggian 1 m di tengah pelat. Penentuan kerusakan dampak ditunjukkan dengan penyerapan energi disebabkan retak awal hingga retak keruntuhan dan defleksi selama peristiwa tumbukan. Hasil menunjukkan bahwa kinerja mortar ringan pada SG 1.4 Pozolan lebih baik dari SG 1.6 Pozolan, SG 1.2 Pozolan dan SG 1.4 Non Pozolan dalam menyerap energi akibat beban impact. Kata kunci: ferrofoam concrete, impact test, pozolan, drop-weight test Abstract Non-structural constructions are prone to damage due to impact loads. One of the efforts to overcome this problem is by using ferrocement which is able to provide good shock resistance. The ferrocement matrix can innovate using lightweight concrete which has been widely used, one of which uses foam which is known as ferrofoam concrete. The purpose of this study was to observe the impact load capacity on ferrofoam concrete with Pozolan sand and without Pozolan sand so that it can be used in constructions with a high level of shock resistance. A total of 4 plate specimens having a cross-sectional dimension of 400 mm with a thickness of 40 mm were used and 4 layers of wiremesh were assigned. The difference of SG 1200 kg / m³, 1400 kg / m³ and 1600 kg / m³ was taken into consideration with FAS 0.4 and the addition of 10% pozolan sand was determined. The impact load test is applied to the plate by dropping an iron ball of 3 kg from a height of 1 m in the center of the plate. Determination of impact damage is indicated by the energy absorption due to initial crack to crack collapse and deflection during the impact event. The results show that the performance of ferrofoam with pozolan at SG 1.4 is better than SG 1.6, SG 1.2 and SG 1.4 without pozolan in absorbing energy due to impact loads. Keywords: ferrofoam concrete, impact test, pozolan, drop-weight test

Abstract

Abstrak Pandemi Covid 19 pada tahun 2020 dan 2021 telah turut mempengaruhi triple constraints dalam pelaksanaan proyek konstruksi gedung di Provinsi Aceh. Penelitian ini bertujuan untuk mengetahui faktor-faktor dominan yang mempengaruhi triple constraints pada proyek konstruksi gedung di Provinsi Aceh dalam masa pandemi Covid 19. Proyek konstruksi gedung yang ditinjau adalah proyek yang telah selesai dibangun oleh perusahaan kontraktor di Provinsi Aceh, dengan menggunakan sumber dana dari Anggaran Pendapatan Belanja Aceh (APBA) tahun 2020 dan 2021 dan mempunyai nilai kontrak lebih dari 1 miliar rupiah. Penelitian ini menggunakan pendekatan metode kuantitatif melalui kuesioner. Teknik analisis data digunakan statistik deskriptif dan Principal Component Analysis (PCA). Hasil penelitian menunjukkan bahwa faktor-faktor yang mempengaruhi triple constraints pada proyek konstruksi gedung di Provinsi Aceh dalam masa pandemi Covid 19 yaitu faktor eksternal, tenaga kerja, keuangan, dan kontrak dengan total varian (persentase triple constraints) sebesar 66,596% dan faktor dominannya adalah faktor eksternal dengan varian sebesar 31,478%. Kata kunci: Triple constraintsi, Covid 19, PCA  Abstract The Covid19 pandemic in 2020 and 2021 has also affected triple constraints in the implementation of building construction projects in Aceh Province. This study aims to determine the dominant factors and factors that affect triple constraints on building construction projects in Aceh Province during the Covid 19 pandemic. The building construction projects reviewed are projects that have been completed by a contractor company in Aceh Province, using funding sources from the Aceh Revenue and Expenditure Budget (APBA) for 2020 and 2021 and have a contract value of more than 1 billion rupiah. Data analysis techniques used descriptive statistics and Principal Component Analysis (PCA). The results showed that the factors that influenced the triple constraints on building construction projects in Aceh Province during the Covid 19 pandemic were external factors, labor, finance, and contracts with a total variance (percentage of triple constraints) of 66,596 % and the dominant factor was external factors with a variance of 31.478%. Keywords: Triple constraints, Covid19, PCA
