Abstract

Tujuan penelitian yang digunakan adalah mengidentifikasi struktur gedung tidak beraturan yang ditinjau berdasarkan displacement, drift ratio, dan base shear.Metode yang digunakan untuk perhitungan beban gempa adalah statik ekuivalen dan respon spektrum sni 1726:2019. Tinjauan dari analisa ini meliputi, simpangan antar tingkat struktur dan gaya dalam maksimum pada elemen elemen struktur. Metode yang digunakan pada analisa ini adalah analisa statik ekuivalen dan analisa dinamik respons spektrum. Hasil pada analisa ini menunjukkan bahwa nilai simpangan pada arah x dan arah y tidak berbeda jauh antara hasil pada analisa statik ekuivalen dan analisa respon spektrum. Dimana nilai simpangan antar tingkat dari hasil kedua analisa tersebut baik pada arah x dan y tidak ada yang melebihi nilai simpangan antar tingkat izin. Penelitian ini melakukan perbandingan analisis beban gempa statik dengan metode analisis linear dengan mengambaikan fase plastis gedung sehingga tidak diketahui pengaruh pembebanan pada gedung saat gempa melebihi fase plastis struktur. Untuk itu pada penelitian selanjutnya dapat dilakukan penenelitian serupa dengan menggunakan metode nonlinear analisis.

Abstract

Pemantauan ketinggian air sangat penting untuk mencegah kerugian dan korban jiwa akibat banjir. Pengembangan sistem real-time untuk pengambilan keputusan sangat diperlukan dalam konteks ini. Penelitian ini menggunakan metode fuzzy sugeno pada prototipe pendeteksi banjir, dengan ESP 32 sebagai mikrokontroler yang dilengkapi logika fuzzy dan sensor ultrasonik A02YYUW untuk mengukur ketinggian air. Metode ini melibatkan proses fuzzifikasi, inferensi, dan defuzzifikasi. Pengujian menunjukkan sensor ultrasonik A02YYUW memiliki rata-rata eror sebesar 0,1% dan waktu respon pengambilan keputusan fuzzy sekitar 0,115 detik. Simulasi menggunakan matlab menghasilkan rata-rata eror 0%. Dengan demikian, pendeteksi banjir ini menggunakan sensor ultrasonik A02YYUW dan metode fuzzy sugeno dapat menjadi solusi efektif untuk memantau dan menginformasikan kondisi ketinggian air guna mengurangi resiko banjir.

Abstract

Roads are very important transportation infrastructure in traffic flow. When there is a road section that is damaged, it will have a significant impact on traffic flow. Roads can be analyzed to determine the cause of the damage and repair alternatives. This study aims to determine the types of damage and road pavement conditions so that they can be determined how to repair them. The method used in this study is the PCI (Pavement Condition Index) method. Initial research on the condition of the road surface is to conduct a survey by observing and analyzing the road based on the types of damage to be used as a basis for carrying out road maintenance and repairs. To determine and group the types and levels of pavement damage, and determine the value of the pavement condition by finding the PCI (Pavement Condition Index) value and repair efforts. The results of damage to the Urip Sumoharjo road section, Bandar Lampung are marked with STA 0 + 000 - 3 + 000. The PCI value on the road section is 65.3% with good conditions based on the rating. The types of maintenance carried out to improve the level of road service according to the highway regulations on this section are asphalt coating, patching, and leveling.

Abstract

Indonesia is one of the countries with a high earthquake risk, because it is located on the Pacific Ring of Fire, precisely at the intersection of three large tectonic plates. The object of this study is a three-story dormitory building that accommodates many students, so structural reinforcement is needed so that they can save themselves when a disaster occurs. The purpose of this study is to analyze earthquake-resistant beams according to the SNI 1726:2019 reference, so that the beam enlargement is obtained from the initial dimensions of 25 x 50 cm to 40 x 50 cm due to earthquake loads. The longitudinal reinforcement requirements for the supports are 3D19, 2D13, 3D19, while for the field it is 3D19, 2D13, 3D19. For stirrup reinforcement, 2D13 - 100 are needed at the supports and 2D13 - 150 in the field, all of which meet the requirements for flexural, shear, and torsion capacity according to SNI 1726:2019. However, this abstract does not highlight the uniqueness of the research, such as the specific approach taken to meet the requirements of SNI 1726:2019, as well as innovations in research methods or results. In addition, the details of the results are not specific, especially regarding the direct impact of changes in beam dimensions on building safety. The addition of quantitative information, such as structural efficiency or increased flexural and shear capacity, would provide a clearer picture of the contribution of this research to building safety.

Abstract

Mas Kus Layer Chicken Farm uses groundwater to meet its clean water needs. There is not enough groundwater on this farm to meet all clean water demands. To increase the availability of clean water, a Rainwater Harvesting (PAH) system was installed as a backup plan and an effort to use natural resources. A hydrological approach was used to analyze the maximum daily rainfall, which was then used to collect rainwater. This study used a quantitative descriptive methodology, and the rainfall of Mas Kus Layer Chicken Farm, the roof area of the building, the capacity of the reservoir, and the need for clean water provided supporting data. The results of the analysis showed that the potential for rainwater harvesting could meet up to 99% of the total clean water needs at Mas Kus Layer Chicken Farm. The storage system used is a Ground water Tank measuring 10x10x2.26 m. With this capacity, the rainwater that can be collected reaches 7,530 liters/day or 7.53 m3/day so that in one month it can accommodate around 226 m3/month.

Abstract

Concrete is a major construction material that is often used in modern construction due to its flexibility and durability. This study aims to examine the potential of green mussel shells as a partial substitute for fine aggregate in concrete mixtures. Green mussel shells, which are mostly composed of calcium carbonate, offer an environmentally friendly solution by utilizing waste to support the sustainability of the construction industry. This study used an experimental method with variations in green mussel shell substitution of 0%, 5%, 10%, 15%, and 20%. The concrete making process involves mixing cement, coarse aggregate, fine aggregate, water, and crushed mussel shells. The concrete compressive strength test was carried out after curing for 28 days. The results showed that the higher the percentage of mussel shell substitution, the lower the compressive strength of the resulting concrete. At low substitution (5%-10%), concrete still meets the criteria for non-structural applications, with an average compressive strength ranging from 8.37 MPa to 9.05 MPa. At high substitution (15%-20%), the compressive strength of concrete decreased significantly to an average of 6.48 MPa. Substitution of green mussel shells has the potential as an alternative material in concrete, taking into account the maximum limits of its use to maintain the mechanical performance of concrete.
