Abstract

Abstrak: Hasil hitungan daya dukung pondasi tiang yang didasarkan pada teori mekanika tanah, sebaiknya perlu dicek dengan mengadakan pengujian tiang untuk meyakinkan hasilnya. Salah satu pengujian tiang yang dilakukan adalah Pile Driving Analyzer (PDA) Test. Penelitian ini membandingkan nilai daya dukung SPT menggunakan 3 metode yaitu Metode Meyerhof, Poulos Davis, dan Luciano Decourt dengan hasil daya dukung PDA Test serta mengetahui rumus perhitungan daya dukung SPT yang paling mendekati hasil PDA Test. Nilai daya dukung ultimit (Qu) pondasi tiang bor tunggal yang dihitung dengan Metode Meyerhof dan Luciano Decourt menggunakan data SPT sudah mendekati nilai daya dukung PDA Test. Sehingga daya dukung SPT dikatakan mampu memprediksi daya dukung pondasi dengan baik Sedangkan metode Poulos Davis hasilnya jauh dari metode lainnya karena tidak memperhitungkan koreksi nilai N-SPT. Nilai daya dukung hasil PDA relatif lebih besar dikarenakan itu pada saat pelaksanaan pengeboran tiang, bentuk dinding tiangnya tidak seragam sehingga luas ujung tiang dan selimut tiang bertambah dan menyebabkan daya dukung menjadi lebih besar. Metode yang paling mendekati hasil Qu PDA adalah Metode Meyerhof, terbukti ada tiga titik yang selisih nilai daya dukungnya kecil. Hal ini dikarenakan pada Metode Meyerhof dilakukan koreksi pada nilai N-SPT.Kata-kata kunci: Daya Dukung Tiang Bor, Daya Dukung SPT, Daya Dukung PDA Test.Abstract: Bearing capacity of pile foundation based on soil mechanics theory, should be checked by conducting pole test to assure the result. One of the pole tests performed is the Pile Driving Analyzer (PDA) Test. This study compares the value of SPT support capacity using 3 methods, Meyerhof Method, Poulos Davis, and Luciano Decourt with the result of PDA Test bearing capacity and know the formula of calculation of SPT bearing capacity closest to PDA Test result. The value of bearing capacity (Qu) of single mast pile foundation computed by the Meyerhoff and Luciano Decourt Methods using SPT data is close to the bearing capacity of the PDA Test. So SPT bearing capacity is to be able to predict the bearing capacity of the foundation well. While the Poulos Davis method is far from other methods because it does not take into account the correction of N-SPT value. The value of the bearing capacity of the PDA results is relatively greater because of the time of drilling the pile, the shape of the pile wall is not uniform so that the pole end and the shaft of the pole increases and causes the bearing capacity becomes larger. The method that most closely approximates Qu PDA is Meyerhof Method, there are three points where the difference of the small bearing capacity value. This is because the Meyerhof Method corrected the N-SPT value.Keywords: Bored Pile Bearing Capacity, SPT Bearing Capacity, PDA Test .

Abstract

Drainage on the Lekso River in Blitar City is experiencing various problems, such as clogged channels, damage to infrastructure, and accumulation of garbage. Based on these problems, community service activities were carried out with the aim of assisting Drainage Maintenance on the Lekso River, Blitar City. The method used in this service is identification of drainage problems and needs through field surveys and consultations with relevant authorities and outreach to the community regarding the importance of maintaining good drainage and environmental management. As a result of this community service, the community receives training and education assistance for the community regarding proper drainage maintenance techniques, such as channel cleaning, infrastructure repair, and waste management. In addition, the local community carried out drainage cleaning and repair activities together with the guidance and supervision of the community service team.

Abstract

This study analyzes the compliance of the lighting utility system in the library of SMP Negeri 4 Malang City against the Indonesian National Standard SNI 6197:2011. A quantitative descriptive method with a case study approach was employed, using direct lux meter measurements at 80 grid points (A1–H10) conducted between 13:00 and 15:00 under clear weather conditions to capture optimal natural lighting data. Results indicate that illuminance levels range from 135.40 lux to 355.50 lux; however, the distribution is highly non-uniform. Only Zone A, located nearest to the primary openings, consistently meets the 300 lux minimum standard, while more than 75% of the measured area falls below this threshold and is classified as under-lit. Contributing factors include restricted natural light penetration, a solid wall on the eastern façade blocking that light path, and dense interior shelving that obstructs light propagation toward central and rear zones. The study concludes that the current lighting system does not fully satisfy SNI 6197:2011 requirements, and recommends the addition of artificial lighting fixtures, optimization of interior furniture layout, and enhancement of façade opening design to improve visual comfort for library users
