Abstract

Concrete structurally has big compression strength, but it has weaknesses in lower tensile strength and fragile in nature. These weaknesses can be improved by adding steel fiber into concrete mixture evenly with random orientation. The objective of this research is to find out and study the influence of fiber fraction volume to the compression strength and tensile strength concrete. The objects to test consist of 24 fiber concrete cylinders with dimension of 150 mm x 300 mm for compression strength test and tensile strength. The fiber used local fiber (from steel wire with lf/df 60), with fiber fraction volume values of 0%; 0.2%; 0.4%; and 0.6% and the addition of 0.4% superplasticizer from cement weight for respective fraction volumes. Time testing done at the time when concrete was 28 days. The results showed that the addition of steel wire fiber in the concrete mixture reduced the level of workability of the concrete mixture. The statistic test results showed improvements of compression strength and tensile strength, of the fiber concrete fraction volume 0.4%. The increase of compression strength concete reached at the volume of 0.4 % fraction of 20,8132 % with the value of 33,40243 MPa and tensile strength concrete reached at the volume of 0.4 % faction of 3.24 % with the value of 2,9227 MPa.

Abstract

Pemilihan jurusan di SMA/MA pada dasanya memerlukan pertimbangan yang sangat matang, dikarenakan pemilihan jurusan merupakan langkah awal dalam menentukan karir siswa untuk masa yang akan datang. Dalam menangani proses pemilihan jurusan biasanya dilakukan oleh bagian kesiswaan dan prosesnya dimulai saat para calon siswa mendaftar, siswa nantinya akan diberikan kesempatan untuk memilih jurusan yang mereka inginkan, namun pilihan dari siswa tersebut tidak sepenuhnya menjadi keputusan mutlak. Bagian kesiswaan menentukan jurusan para calon siswa berdasarkan nilai raport SMP/MTS, nilai UN SMP/MTS, rekomendasi guru BK di SMP/MTS, hasil tes penempatan di SMA, dan tes bakat dan minat oleh psikotes serta kuota yang tersedia di jurusan yang dikehendaki. Tujuan penelitian adalah agar siswa-siswi Madarasah Aliyah Negeri 2 dapat menentukan jurusannya. Pengujian dalam pemilihan jurusan menggunakan sistem pendukung keputusan metode MOORA, yang mana metode MOORA dapat memecahkan masalah dengan perhitungan matematika yang kompleks. Dari pengujian metode MOORA tersebut dapat dihasilkan dari populasi dan sampel yang di implementasikan mendapatkan jurusan masing-masing sesuai dengan penilaian metode MOORA. Abstract The selection of majors in SMA/MA basically requires very careful consideration, because the selection of majors is the first step in determining students' careers for the future. In handling the selection process, the department is usually carried out by the student department and the process begins when prospective students register, students will be given the opportunity to choose the major they want, but the choice of the student is not entirely an absolute decision. The student department determines the majors of prospective students based on the report scores of SMP/MTS, SMP/MTS UN scores, BK teacher recommendations in SMP/MTS, high school placement test results, and interest by psychological tests and the available quotas in talented majors. The purpose of this research is that the students of Madarasa Aliyah Negeri 2 can determine their major. The test in the selection of majors uses a decision support system using the MOORA method, in which the MOORA method can solve problems with complex mathematical calculations. From testing the MOORA method, it can be generated from the population and the sample implemented to get their respective majors in accordance with the assessment of the MOORA method.

Abstract

Poor sanitation is a serious problem that still occurs, especially in areas that do not yet have an independent waste management system. This condition has a significant impact on public health, especially increasing the risk of environmental diseases such as diarrhea, cholera, and typhus. In addition, inadequate sanitation can also pollute clean water sources and soil, damage ecosystems, and reduce the quality of life of the community as a whole. Pekon Gisting Permai as one of the areas in Tanggamus Regency, Lampung Province which is currently developing, also faces challenges in terms of sanitation. Many houses do not yet have proper sanitation facilities such as septic tanks, so that human waste (feces and urine) is disposed of carelessly in the surrounding environment. This not only causes an unpleasant odor, but also becomes a potential source of the spread of disease. A simple septic tank is present as an appropriate and affordable sanitation solution for the community. By utilizing the natural process of waste processing by microorganisms and absorption systems, a simple septic tank is able to reduce the burden of environmental pollution and protect clean water sources. In addition, simple septic tanks are easy to build and maintain, making them suitable for use in areas with limited resources. However, many people still do not understand the importance of good sanitation and the benefits of simple septic tanks. Lack of knowledge about how to build, operate, and maintain simple septic tanks is also an obstacle to their implementation.
