Abstract

The purpose?s of research are: 1) to investigate the implementation of the credit points system by the SDU in improving student?s discipline attitude at SMAN 2 Ngawi; 2) to know the impact of the system credit point?s implementation by the SDU about the student?s discipline attitude in SMAN 2 Ngawi.This research used a qualitative approach with descriptive research form. The source of data  that  be used consist of: informants, observation sheet  and document analysis sheet. The sampling technique  that be used was aims samples (purposive sampling). The technique of collecting data through interview, observation and documentation. The validity of the data by using a triangulation of data or sources. The data analysis technique  that be used was interactive analysis model which consists of four major components, namely data collection, data reduction, data presentation and conclusion.The results indicated that the implementation of the credit points system by SDU was  implemented through three programs: 1) keeping the gate operation was carried out every day at 6:00 am to 7:00 am except during mid semester or semester test, 2) class raid is conducted between the two times up to four times a month, 3) operation before the flag ceremony every Monday. There are form of attitude that  be showed  by the students of SMAN 2 Ngawi had been embedded discipline character include: 1) most of students don?t come late to school, 2) most of students complete the attributes and school uniforms; 3) following the school teaching , did not make some noises during school hours , no ditching, 4) always follow the flag ceremony except during illness; 5) did not carry unnecessary items to school, 6) did not streak benches and walls; 7) keeping the school cleaning.

Abstract

Pasir adalah bahan bangunan dengan material paling banyak dipergunakan baik dari struktur bangunan bagian bawah hingga struktur bagian bangunan paling atas, Setiap pasir memiliki perbedaan karakteristik sesuai pasir itu diperoleh. Setiap pasir yang diperoleh mempunyai ciri khas. Beton adalah konstruksi yang tersusun oleh material semen, air, kerikil merupakan agregat kasar. Pasir yang digunakan pada penelitian ini ada dua macam, yaitu pasir Galunggung yang berasal dari Kabupaten Tasikmalaya dan pasir Cimalaka dari Kabupaten Sumedang. Penelitian ini menunjukkan kuat tekan yang dipengaruhi pasir Cimalaka dengan pasir Galunggung. Penelitian ini menggunakan beton dengan mutu rencana 20 MPa, umur pengujian yang digunakan adalah 28 hari, untuk pengujian kuat tekan. Hasil pengujian menunjukan pasir Galunggung mempunyai nilai kuat tekan tertinggi yaitu 10,716 MPa, kemudian pasir Cimalaka sebesar 11,04 Mpa. Kata Kunci: kuat tekan, beton agregat halus, pasir

Abstract

Beton adalah salah satu pilihan material struktur yang cukup penting dalam mendukung pembangunan sehingga kualitas beton dituntut untuk ditingkatkan melalui penelitian- penelitian. Beton didefinisakan sebagai campuran antara agregat halus (pasir), semen, agregat kasar (kerikil), dan air dengan atau tanpa bahan tambahan sehingga terbentuk massa padat. Batujajar Kabupaten Bandung Jawa Barat dikenal dengan banyaknya industri batu belah yang menghasilkan limbah abu batu degan jumlah yang cukup banyak. Kriteria dari abu batu adalah lolos ayakan berdiameter 4,75 mm dan bertahan di ayakan 0,075 sehingga abu batu merupakan limbah yang bisa dijadikan alternatif pengganti agregat halus/ pasir untuk pembuatan beton. Penelitian ini bertujuan mengetahui kadar optimum pemakaian abu batu dalam menggantikan pasir pada pembuatan beton. Pada penilitian ini juga mengukur tingkat efektifitas kuat tekan beton dan berat jenis antara beberapa variasi adukan Pasir Alami (PA) Abu Batu (AB). Hasil penelitian menunjukkan bahwa kuat tekan rata- rata tertinggi dihasilkan dari beton dengan proporsi PA 60 % : AB 40% yaitu 12,76 MPa. Pemeriksaan berat volume beton menunjukkan proporsi AB 20 % : PA 80% menghasilkan berat volume rata- rata terbesar yaitu 2,27 gr/cm3 sedangkan pada proporsi PA 40 % : AB 60% nilai berat volume 2,25 gr/cm3. Penggunaan abu batu sebagai pengganti sebagian pasir meningkatkan kuat tekan beton namun tidak signifikan meningkatkan berat volume beton.

Abstract

In a construction project activity, a Cost Budget Plan (RAB) is very important to get a price that is in accordance with what you want to build, and really helps contractors not to suffer losses. In fact, what happens in the field is that the Budget Plan (RAB) is not exactly the same as the Implementation Budget Plan (RAP) and that happens in every project that is implemented. The labor coefficient obtained from the labor requirement per work volume is in fact also not evenly distributed in every region in Indonesia which is called the SNI method. The general description of the project that is used as the object of research is the Building Construction Study Program Building, Tedc Bandung Polytechnic. Where the value of this project is Rp. 1,610,144,148,000. The implementation time plan is needed as a guideline for arranging the time for carrying out work that is responsible for the late project being determined from week 1 to week 14. After all the data has been collected, data processing is carried out. Based on the Yield Value Concept method, there are several initial steps, namely determining ACWP indicators for the 1st week = Rp. 3,230,827.42 and the 14th week ACWP = Rp. 6,696,150.38, BCWP 1st week = Rp. 2,657,616.10 and the 14th week BCWP = Rp. 6,917,618.39, BCWS 1st week =. Rp. 3,543,488.14 and the 14th week BCWS = Rp. 7,360,554.41.

Abstract

The infrastructure facility makes a major difference in human life. Its progression has definitely been for good and for bad. One of the bad effects is global warming. For repressing the harmful effects requires a new concept that remains environmental. The medical facility support building at the medical center in Bandung is still on its way to implementing the concept of green building. The building is planned to add solar power systems to its energy source. This Solar system is planned to apply on the roof. According to the roof's calculations, the number of solar panels should be installed at 250 units and require 33 units inverter. The installation of this system eventually affected the structure of roof plates. The building's inner design involves a steel framing structure for columns and beams. Reinforced concrete slab roof is used. The structure of the Structure Of Order Bearers Special Moments (SRPMK) referred to the area of the earthquake 4. The earthquake load calculations used an equatorial static that works on the portal passage. Style-counting analyzer in manually counted and of sap2000 version 14.0.0. Portal planning uses Load Resistance Factor Design (LRFD) method to determine the profile used. After calculations were made, it was found that the dimensions of the secondary beam contained wf 200x200, the columns used the 400x400 profile and the main beam used the wf 400x200 and 350x350 profiles.
