Abstract

Concrete is the main component of construction materials in Indonesia. Concrete composition materials consist of cement, sand, gravel, and water. Cement production in Indonesia in fact often causes polemic in the community. The community often complains of environmental pollution resulting in the cement production process. Shellfish from various mollusks like that are available abundantly along the coastal areas in Indonesia. Blood clam (Anadara granosa) is one of the many shells found in Indonesian waters and is consumed by many people because of its high protein content. Shells are part of the clam that cannot be consumed so they only accumulate into household waste. Seashell waste can be an environmental problem if not handled properly. The conch shell contains lime, silicate and alumina. The aim of this study was to determine the effect of the Anadara granosa shell as a substitute for a portion of cement in the manufacture of normal concrete. Stages of research conducted in the form of making normal concrete without any added material, making concrete with Anadara granosa shell as a partial replacement for cement, and testing the compressive strength of normal concrete samples. The optimum level of Anadara granosa shell waste as a substitute material for a portion of normal mixed concrete cement is 3% of the weight of cement used. The optimum compressive strength of concrete with Blood Shells waste as a substitute for some cement is at 30.62 MPa. The effect of Anadara granosa shell as a partial cement substitute in making normal concrete can reduce the compressive strength along with the addition of Anadara granosa shell as a partial cement substitute. Keywords: blood shells, cement, compressive strength, concrete

Abstract

Project risk is an uncertain situation in a project so that it can lead to consequences that can hinder the achievement of the main project objectives. Risks to the project need to be identified and analyzed in order for the project to run well. The Hidayatul Qur'an Lissa'adah Islamic Boarding School construction project is a self-managed construction project that experienced delays in its implementation time based on the results of observations and preliminary interviews with the development committee. With risk management aims to identify and reduce the risks that occur in the implementation of the Hidayatul Qur'an Lissa'adah Islamic Boarding School construction project so that the project can be completed immediately. Project delays cannot be separated from the existence of several risks that cannot be avoided, but can be minimized by risk management. In this study, identification with the Cochran q-test was carried out on the risks to determine the risks that greatly affect delays in the project, then carried out an analysis of the risks that occurred with the saverity index and then carried out appropriate mitigation actions against these risks, so that the project could be completed immediately. Based on tests and calculations using the Cochran q-test and saverity index. The results obtained through this study are that there are 4 dominant risks in the medium and high categories, namely the risk of incorrect or incomplete design (11.39%), the risk of cash flow congestion (11.39%), the risk of problematic service providers (20.25 %) and the risk of the covid pandemic outbreak (31.64%).

Abstract

Cement setting time is the time required for cement to harden, calculated from when the cement begins to react with water to form a paste. Cement setting time refers to the period of time required for cement paste mixed with water to become stiff enough to form a structure and bind construction materials. The purpose of this study was to determine the normal consistency of cement and cement setting time for PCC and OPC cement. The results of this study are for the Normal Consistency test of Portland Cement PCC Ex. Tiga Roda with a penetration target of 10 mm obtained a water content of 30.8%. Normal Consistency test of Portland Cement OPC Ex. Tiga Roda with a penetration target of 10 mm obtained a water content of 26.4%. Testing the Setting Time of Portland cement PCC Ex. Tiga Roda obtained penetration at Initial Setting of 112 mm, Final Setting of 210 mm. Testing the Setting Time of Portland cement OPC Ex. Tiga Roda obtained penetration at Initial Setting of 111 mm, Final Setting of 210 mm.

Abstract

Sebagai salah satu moda angkutan massal yang banyak diminati oleh masyarakat, kereta api dalam operasionalnya tidak dapat dihindari bila jalan relnya pasti bersinggungan dengan jalan umum. Tak terkecuali jalur kereta api yang datang dan berangkat dari stasiun Ngrombo Purwodadi yang bersinggungan dengan jalan Solo- Purwodadi. Kelancaran operasional kereta api dan konflik kelancaran lalu lintas jalan Solo- Purwodadi berkumpul menjadi satu simpul di perlintasan kereta api jalan Solo- Purwodadi. Perkembangan pembangunan dan pertumbuhan penduduk di sekitar rel dan perlintasan jalan Solo- Purwodadi muncul karena tuntutan ekonomi masyarakat. Jalan Solo- Purwodadi sendiri merupakanjalan akses masuk Kota Purwodadi sekaligus jalan antar propinsi yang memiliki nilai ekonomi yang potensial. Dengan meningkatnya permintaan transportasi antar kota dengan menggunakan kereta api maka berdampak pada penambahan jadwal operasional kereta dan berefek pula pada kemacetan jalan Solo- Purwodadi karena seringnya kereta api yang melintas. Tujuan dari studi ini adalah untuk mengetahui tingkat keselamatan dan keamanan di perlintasan jalan kereta api dengan jalan Solo- Purwodadi Kabupaten Grobogan, mendapatkan informasi yang berkaitan dengan Perilakau berkendara di perlintasan kereta api jalan Solo- Purwodadi, dan mengidentifikasi kebutuhan infrastruktur keselamatan dan keamanan di perlintasan kereta api jalan Solo- Purwodadi. Manfaat lain yang bisa diambil dari studi ini diantaranya sebagai masukan bagi pihak-pihak terkait dalam membuat desain perlintasan jalan Solo- Purwodadi yang sesuai dengan kondisi dan situasi lingkungan setempat serta upaya-upaya untuk meminimalkan kecelakaan transportasi akibat perilaku berkendara yang kurang disiplin di perlintasan jalan kereta api jalan Solo- Purwodadi.Metode yang digunakan adalah dengan pengamatan langsung kelokasi yaitu ke perlintasan kereta Ngrombo ruas jalan Solo- Purwodadi dengan mencatat perilaku berkendara yang di kelompokan menjadi tiga katagori yaitu menerobor pintu perlintasan, melanggar marka jalan dan merebor arus lalu lintas.Dari data yang ada dapat disimpulkan bahwa kendaraan yang paling banyak melanggar adalah sepeda motor yaitu menggunakan lajur kendaraan arah yang berlawanan sebanyak 110 kendaraan sepeda motor.
