Abstract

Dampak pencemaran air limbah rumah tangga dapat menyebabkan terganggunya kehidupan organisme air karena berkurangnya kandungan oksigen, terjadinya ledakan populasi ganggang dan tumbuhan air, pendangkalan dasar perairan, punahnya biota air, banjir serta menjalarnya wabah penyakit. Adapun penyakit yang ditularkan melaui air dikelompokkan 4 kategori yaitu water borne diseases, water washed diseases, water based diseases, dan water related insect vector diseases. Kondisi sosial dan pengetahuan yang cukup rendah dari masyarakat Dusun Rumambe II Desa Anggadita Karawang dapat memicu dampak pencemaran air. Salah satu usaha untuk mengatasi permasalahan tersebut adalah dengan melaksanakan sosialisasi penanganan air limbah rumah tangga dengan memberikan pengetahuan kesehatan lingkungan, air bersih, sanitasi lingkungan, dan sistem pengolahan air limbah rumah tangga. Bentuk sosialisasi tersebut berupa penyuluhan dan diskusi. Sosialiasasi tentang air limbah, air bersih, masalah dan indikator kesehatan lingkungan, contoh sanitasi lingkungan yang baik dan buruk, penyakit yang dapat ditularkan melalui air, sistem pengolahan air limbah rumah tangga, dan pencemaran lingkungan kepada masyarakat dusun Rumambe II diharapkan mampu mengubah kebiasaan yang salah sehingga mampu menciptakan lingkungan yang sehat dan nyaman.

Abstract

Sawdust waste from the furniture industry should be considered. Nowadays, the increased demand for furniture is in line with the increase in sawdust waste produced. Therefore, it is necessary to make use of sawdust to protect environment. An alternative use is the addition of sawdust as the concrete mixture. Cellulose and hemicellulose compounds are compounds contained in wood powder, where these compounds can provide additional bonding between particles in the cement and sand mixture in concrete. Therefore, concrete can be stronger as well as more water resistant, hence it can be used for a specific purpose in constructions. This study aims to analyze the compressive strength of concrete due to the addition of sawdust as an organic fiber in the concrete mixture with the percentage of 0.25%, 0.50%, 0.75% and 1% as substitution of sand. Organic fibers as additives in concrete are being developed until recently. The proposed concrete was 25 MPa quality. Result showed the increase in the compressive strength of concrete by 0.98% in 1% wood powder mixed at 28 days of concrete age.

Abstract

Penggunaan material beton di dunia konstruksi semakin beragam, baik bentuk maupun secara mutunya. Ada tipe pekerjaan struktur beton yang membutuhkan waktu pengerasan yang dipercepat, dan ada beberapa pekerjaan yang membutuhkan waktu diperlambat. Apabila jarak batching plant ke lokasi proyek cukup jauh dan terjadinya kemacetan di jalan, sehingga membutuhkan waktu transportasi yang lebih lama, maka dibutuhkan bahan tambah pada campuran beton, untuk dapat memperlambat waktu setting beton tanpa harus mengurangi mutu beton itu sendiri. Dari dasar itulah diperlukan bahan tambah yang berfungsi sebagai memperlambat setting time beton (retarder). Umumnya bahan dasar yang mengandung gula dapat dipakai sebagai retarder. Gula pasir merupakan suatu bahan yang banyak tersedia dan mudah di dapat. Pada penelitian ini untuk mengetahui nilai slump, uji kuat tekan beton, dan uji setting time dari beton yang ditambahkan larutan gula pasir. Penelitian ini menggunakan metode studi eksperimental. Pada setiap campuran beton ditambahkan larutan gula pasir yang bervariasi mulai dari 0,25%, 0,5%, dan 2,5% dari berat air. Berdasarkan hasil penelitian, didapatkan bahwa beton dengan bahan tambah larutan gula pasir 0,25%, 0,5%, dan 2,5% membutuhkan waktu ikat lebih lama dibandingkan dengan beton normal. Disamping itu dari segi nilai kuat tekannya, beton dengan bahan tambah larutan gula pasir 0,25% menunjukkan nilai kuat tekan 22,99 MPa pada umur 28 hari naik sebesar 2,73% dari beton normal dan 0,5% menunjukkan nilai kuat tekan 22,55 MPa pada umur 28 hari naik sebesar 0,76% dari beton normal, sedangkan pada beton dengan bahan tambah larutan gula pasir 2,5% menunjukan hasil tidak mencapai nilai kuat tekan beton yang diisyaratkan.

Abstract

n construction work, it is often found that unused building materials / materials are disposed of as waste.If the waste is disposed of carelessly, it can cause new problems in the environment. Ceramic shard waste is anexample of a ceramic factory or building construction work. If you can process it creatively, it will produce amore useful product. The purpose of this study was to analyze the comparison of the results of the compressivestrength of concrete in normal concrete and concrete using ceramic waste. The author conducted this researchby comparing the results of the Slump Test and the results of the compressive strength of normal quality fc 25concrete with fc 25 concrete which has been added with ceramic waste as much as 20% and 40%. The test objectused in this study is a cylinder with a size of Ø15 cm x 30 cm, for each experiment as many as 6 specimens, witha compressive strength test carried out at the age of 7,14,28 days after first curring. From the results of this study,the slump value of fc 25 Normal Concrete and fc 25 Concrete with added ceramic waste material meets thestandard of slump target 7.5 cm to 15 cm, for plates, beams, columns and walls according to SNI 03-2834- 1992),and from the results of the compressive strength of fc 25 concrete with the use of ceramic waste by 20%, thecompressive strength of concrete is 21.36 MPa and the use of ceramic waste is 40%, the compressive strength ofconcrete is 17.68 MPa which is smaller than the compressive strength. Normal concrete fc 25 is 27.19 Mpa. Fromthe results of the concrete compressive strength, it can be seen that there is a decrease in the compressive strengthof the concrete due to an increase in the percentage of ceramic waste. So that it can be concluded that the use ofceramic shard waste composition is not recommended for building construction structures

Abstract

A storage building is a structure that has specified requirements for usage as a container or location anda high load value. As a result, it is crucial to check or examine the building's structure. There are two separateparts to the building structure, one of which is horizontal. Elements that bear loads working transversely andtransfer the load to a supporting column are known as horizontal elements, sometimes known as bending elements.It is crucial to assess the safety of horizontal elements like beams and slabs since they serve as the floor's bondingand reinforcing frames in superstructures. This final project attempts to assess the shear forces and momentsapplied to the floor slabs and beams, the reinforcement ratio applied to the beams, and the beam deflections thatresult. The presentation in this study makes use of ETABS v.17.0.1 software and secondary data. The 3rd floorhas the largest shear force in the X direction with a value of 59.3292 kN and the largest moment in the X directionwith a value of 128.9298 kN-m, while the 3rd floor has the largest shear force in the Y direction with a value of47.1916 kN and the largest moment in the Y direction with a value of 92.7026 kN-m. According to the result ofETABS v.17.0.1, the beam reinforcement ratio is 0.82 percent, and the maximum deflection permit limit formulauses SNI 2847:2019 to get the permitted deflection value of 25 mm.

Abstract

Road is a land transportation infrastructure that plays an important role in the land transportation sector, withvery rapid economic growth, there is a surge in road traffic users, while the capacity and performance of roadsthat accommodate the flow of vehicles is not comparable to the surge. The growth of small businesses along theroad makes traffic performance decrease, road side constraints have a very large role on road performance andcapacity. Pedestrians, people crossing, entering and exiting vehicles, vehicles slowing down and also vehiclesstop on the side of the road. Jalan Ir. H. Juanda Bekasi has become the research location, because this road sideactivity is relatively high, causing delays in vehicle speed or traffic jams. The number of access roads in and outof housing is also one factor other than those mentioned above. This research was conducted for 7 (seven days),starting on Monday, November 26, 2018 until December 2, 2018. Retrieval of data through direct observation onthe research object, for traffic volume, vehicle speed and side obstacle data are divided per 15 minutes . Dataanalysis was then performed namely traffic volume, speed, density and road capacity using the Indonesian roadcapacity manual (MKJI) 1997. From the results of the study, obtained a value of capacity without side obstaclesof 1520 Smp/hour, and with side obstacles of 1458 smp/hours, then obviously the service capacity of the road hasdecreased, (DS) by 1.39 from the highest daily yield, and calculated (DS) for the next five years by 2.19 Thisshows that the road side barriers on Ir. H. Juanda Bekasi is very high and very influential on the performance oftraffic capacity.
