Fynnisa Z — 2023-08-04

Water is one of the most vital sources of livelihood for all living things on earth. However, not all people have the ability to process water. Datuk Bandar District is one of the areas that has a large number of residents and facilities for schools, offices and other public facilities. In this study, we analyze the demand for domestic and non-domestic clean water in Datuk Bandar District for the next 20 years by projecting the need for population growth until 2041 based on data from the Central Statistics Agency. The method used in this study is the method of arithmetic, geometry, and least square. From the results of the analysis, the projected population of Datuk Bandar Subdistrict in 2041 using the geometric method is 81,670 people and the projected clean water needs of 85,105 l/second, while for now the production capacity of PDAM Tirta Kualo for Datuk Bandar Subdistrict is in WTP II service, namely of 90 l/sec. so that until 2041 the need for clean water for Datuk Bandar District is still fulfilled.

UJI ULTRASONIC PULSE VELOCITY PADA BETON NORMAL YANG MENGGUNAKAN BATU KARANG SEBAGAI PENGGANTI KERIKIL

Alva Yuventus Lukas — 2023-08-07

Meluasnya penggunaan beton dalam konstruksi bangunan mengakibatkan kebutuhan lebih banyak pada bahan penyusun beton. Masalah yang timbul, turunnya jumlah material penyusun beton yaitu kerikil. Pecahan batu karang atau crushed coral limestone adalah salah satu alternatif yang dapat digunakan untuk mengatasi hal tersebut. Tujuan penelitian adalah untuk mengetahui kualitas beton menggunakan batu karang sebagai pengganti kerikil pada variasi 5%, 25%, 50%. dan pengaruh umur beton, mutu beton dan prosentasi batu karang terhadap kecepatan rambat gelombang menggunakan UPV. Metode penelitian adalah experimen laboratorium. Kesimpulan penelitian adalah batu karang pulau timor dengan prosentasi 25% dapat digunakan sebagai material alternatif pengganti kerikil dengan rata-rata gelombang UPV 4,56 km/s dan usia beton 28 hari, menunjukan kualitas beton berada pada kategori “bagus” dan koefisien variasi pada kategori “sangat bagus (excelent)”. Sedangkan pada penambahan batu karang sebesar 5% dan 25%, terjadi peningkatan kecepatan gelombang UPV, dan menurun pada variasi 50%, penggunaan batu karang.

FLEXURAL CAPACITY OF REINFORCED CONCRETE BEAMS WITH CIRCULAR OPENINGS AND REINFORCEMENT DETAILING IN COMPRESSION AND TENSION ZONES

Ghalib Setyo Budi — 2023-08-17

The pipes placed below the beams are intended for aesthetic purposes and are subsequently covered by the ceiling, resulting in an unused space. The height of this space will always be determined by the size of the pipes installed below the beams. One alternative plan to route the piping installations above is by creating circular holes with detailing in the beams. The testing conducted in this study involved the flexural testing of beams with simple supports. The concrete beams used as the flexural test specimens were sized at (10 x 15 x 100) cm. The research results indicate that the capacity of the beams increased due to the presence of holes in the tensile and compressive areas. In terms of percentage, when compared to the control beam, the flexural capacity increased by 13% for BBTE1, 4.425% for BBTE2, 6.667% for BBTA1, and 5.607% for BBTA2. The observation of crack patterns revealed that overall failure in the beams occurred through flexural failure for beams BN, BBTE1, BBTE2, BBTA1, and shear failure for beam BBTA2.

UNSUR SENYAWA KIMIA DARI LIMBAH MASKER MEDIS UNTUK MENINGKATKAN KINERJA CAMPURAN ASPAL

I Gusti Agung Ananda Putra — 2023-09-29

Masker adalah perlindungan pernafasan yang digunakan sebagai metode untuk melindungi individu dari menghirup zat-zat bahaya atau kontaminan yang berada di udara. Meskipun masker sangat diperlukan untuk menghindari penyebaran virus Corona, namun pembuangan masker mengancam lingkungan. Masker medis terdiri dari tiga lapisan, lapisan luar dan lapisan dalam adalah kain non-woven yang tahan air dan lapisan tengah adalah bahan yang meleleh. Sebagian besar, komposisi kimia dari masker medis adalah polipropilena. Pada review ini akan dibahas penggunaan limbah masker yang mengandung polipropilena sebagai bahan aditif dalam pembuatan campuran aspal. Metode yang digunakan adalah studi literatur dari peneliti terdahulu dan analisis penambahan limbah masker yang mengandung polipripilena yang berpengaruh terhadap campuran aspal. Sumber utama refrensi artikel ini berasal dari Research Gate, Science Direct, dan Google Scholar. Ditemukan bahwa unsur senyawa yang paling dominan pada masker medis adalah Si (Silika) sebesar 59,11%. Penambahan silika pada campuran aspal dapat meningkatkan ketahanan terhadap kerusakan alur, peningkatan nilai modulus, dan umur fatigue.

COMPARISON OF MAINTENANCE OF AUTOMATIC AND CONVENTIONAL DRIP IRRIGATION SYSTEMS ON HORENSO CROPS (Greenhouse Keboenumiku Cibodas-Lembang)

Fatwa Ibnu Isa — 2024-01-09

Drip irrigation systems are installed in drylands that can provide stable water so that water delivery is better. With the development of technology drip irrigation systems can be controlled automatically which includes electronic devices to command the state of a system. This research uses 2 methods, namely the conventional method and the automatic drip irrigation method which aims to determine the need for water and fertilizer in Japanese spinach/horenso plants and compare maintenance from cost, time and human labor. The results of the study of water released using conventional methods amounted to 29,228 liters and automatic drip irrigation method amounted to 10,000 liters. The difference of 19,228 liters with a percentage of 66.78%, it can be interpreted that the automatic drip irrigation method is more efficient. The fertilizer spent using the conventional method was 20,120 liters and the automatic drip irrigation method was 9,000. The difference of 11,120 liters with a percentage of 55.26%, it can be interpreted that the automatic drip irrigation method is more efficient. The need for water and fertilizer using the automatic drip irrigation system method is more efficient and effective because in giving it not too much is wasted than using conventional methods.

Marvin Patrick Patty — 2024-01-15

ABSTRACT

Cost budget plan is a careful cost budget planning needed in the implementation of the construction of a project that contains budget details in the form of workers' wages, material costs and tools to be used. The Ministry of Public Works issued an Analysis of the Unit Price of Work in 2016 and updated with the Analysis of the Unit Price of Work 2022 issued on January 5, 2022 through Public Works and Public Housing Regulation number 1 of 2022. In the new classroom construction project, MTS N 6 Central Maluku uses the calculation of the project cost budget according to Unit Price Analysis of Work Minister of Public Works and Public Housing number 28/PRT/2016, this is because planning was carried out before the issuance of Unit Price Analysis of Work 2022. With the Unit Price Analysis of Work update in 2022, the author will use Public Works and Public Housing Regulation number 1 of 2022 as a basis for review to analyze the Cost Budget Plan for the MTS N 6 Central Maluku project.

ANALISIS BANGKITAN DAN PEMODELAN PERGERAKAN MAHASISWA UNIVERSITAS PEMBANGUNAN NASIONAL "VETERAN" JAWA TIMUR

Dwi Citrawati — 2024-01-17

Masalah di bidang transportasi sering timbul akibat pesatnya pertumbuhan penduduk yang berbanding lurus dengan meningkatnya jumlah kendaraan, juga terbatasnya fasilitas transportasi. Dalam mengatasi masalah tersebut, diperlukan upaya dalam perencanaan transportasi. Permasalahan laju pertumbuhan penduduk juga berpengaruh pada pertumbuhan sistem pendidikan. Berdasarkan pola pergerakan masyarakat yang cenderung bergerak menuju pusat kegiatan yang dalam hal ini adalah perguruan tinggi, maka akan berpengaruh pula pada kinerja sistem transportasi di sekitar perguruan tinggi. Universitas Pembangunan Nasional “Veteran” Jawa Timur sebagai perguruan tinggi, telah membuka program studi baru yang ditunjang dengan pembangunan gedung baru. Adanya hal tersebut berpotensi menambah daya tampung mahasiswa. Hal ini berpotensi menimbulkan masalah lalu lintas pada ruas jalan di sekitar kampus. Maka penelitian ini dilakukan untuk mengetahui jumlah bangkitan pergerakan mahasiswa Universitas Pembangunan Nasional “Veteran” Jawa Timur yang dihitung dengan matriks asal tujuan menggunakan metode furness yang dipengaruhi oleh faktor-faktor bangkitan perjalanan. Persamaan model bangkitan didapatkan dengan bantuan perangkat lunak SPSS. Dari analisis regresi linear berganda, penelitian ini mendapatkan hasil berupa persamaan model bangkitan Y = 280,429 – 11,355 X1 – 1,873 X3, dimana X1 adalah usia dan X3 adalah jarak tempuh, sedangkan perkiraan jumlah mahasiswa pada umur rencana 5 tahun adalah sebesar 30.098 mahasiswa.
