Abstract

Congestion and delays in urban areas is a critical problem faced by many large cities, especially in the region of East Java, especially in Surabaya has resulted in an increased mobility of people and goods where the rate of vehicle ownership and traffic congestion often occurs highway traffic, the purpose of this study is to find a model suitable to describe the relationship between the length of delay due to the closure of railroad crossings and traffic volume, the degree of saturation of traffic conditions, and queue length variation due to the closure of the old railroad crossings and traffic volume. To obtain sufficient data variation, the data collection for 4 days that is Monday, Tuesday, Wednesday and Thursday with a time of observation for approximately 11 hours starting from 06:00 pm until 18:00 pm. In addition to the data variable traffic volume, long crossings closures, delays and queue length measurements done anyway EMP (passenger car equivalent)During 4 (four) days of observation group the data obtained at the same time closing the crossings with a total sample of 203 groups of data. Old variable closing crossings are used to determine how much influence the closure of crossings to the long delay (delay) and the length of the queue (queue). Variations long closure while crossing tabulated in the appendix to the maximum value, minimum and average length of the closure of crossings is the maximum value of 183.75 seconds, the minimum value of 26.28 seconds, 71.68 seconds average.  Observation of traffic volume made every fifteen-min during the observation period. During the four days of observation obtained maximum value of traffic volume 2,221.60 smp / hour / lane, the minimum value 964.00 smp / hour / lane, average 1,620.47 smp / hour / lane Observations stopped time delay is performed to determine how the average delay experienced by the vehicle during the crossing closed doors. During the 4 days of observation obtained maximum value of stopped time delay 6,832.60 sec vehicle / lane minimum value 81.33 sec vehicle/lane, average 1,197.99 sec vehicle / laneKeyword : Delay Time

Abstract

Dalam industri konstruksi, tender pengadaan barang jasa dilaksanakan untuk memilih perusahaan yang akan menjalankan pekerjaan. Perusahaan yang berminat dan memenuhi syarat dapat mengikuti proses penawaran tender, dan perusahaan terpilih akan melaksanakan pekerjaan berlandaskan kontrak yang telah disetujui.Tingginya persaingan dalam proses tender dan juga kegagalan bagi perusahaan menjadi alasan karya ini dibuat, untuk membantu perusahan perusahan baru dalam memahami dan dapat mengikuti proses lelang maka karya ini disusun Dalam kajian ini menerapkan metode studi literature atau kajian terhadap beberapa artikel, jurnal, buku, dan juga surat edaran yang relevan dengan apa yang ingin dicapai penulis yaitu tentang proses pengadaan barang/jasa pada konsultan konstruksi.Pada hasil dari kajian studi literature pada penulisan ini diketahui bahwa banyak proses yang harus diilakukan unntuk dapat mencapai hasil terbaik pada proses pelelangan penyediaan barang/jasa, dikarenakan banyak peraturan yang telah berubah penting dari pihak penyedia agar dapat juga mengkaji peraturan yang berlaku seperti peraturan terbaru dari Presiden No.1 Tahun 2025 tentang adanya efisiensi anggaran untuk konstruksi, maka dari pihak penyedia wajib dapat menyusun harga yang sesuai dengan sfesifikasi proyek yang dilelangkan dan juga harus tetap dalam batasan nilai efisien yang ada, penulisan ini diharapkan mampu membantu pagi perusahaan kecil atau yang baru membangun usahanya agar dapat ikut bersaing secara adil dan juga sehat.

Abstract

Kegiatan Pengabdian masyarakat ini bertujuan untuk meningkatkan kepedulian sosial masyarakat melalui program bakti sosial yang dirancang secara partisipatif di Desa Janti, Kecamatan Waru. Latar belakang kegiatan ini didasarkan pada masih terbatasnya kesadaran dan keterlibatan warga dalam kegiatan sosial kemasyarakatan, khususnya dalam membantu kelompok rentan seperti keluarga kurang mampu dan lansia. Metode pengabdian menggunakan pendekatan pengorganisasian komunitas dengan tahapan persiapan, sosialisasi dan edukasi, pelaksanaan bakti sosial, serta evaluasi dan refleksi bersama. Kegiatan sosialisasi dilaksanakan dua kali pada tanggal 6 dan 13 September 2025, sedangkan pelaksanaan bakti sosial dilakukan pada 27 September 2025 dengan melibatkan 20 orang warga sebagai subjek pengabdian. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada ketepatan dan kepuasan penerima manfaat serta perubahan sikap dan kesadaran kolektif masyarakat terhadap kepedulian sosial, dari 35% sebelum kegiatan menjadi 80% setelah kegiatan. Temuan ini menunjukkan bahwa bakti sosial yang dikombinasikan dengan proses edukatif dan partisipatif mampu memperkuat modal sosial dan solidaritas masyarakat. Program ini diharapkan dapat menjadi model pengabdian masyarakat yang berkelanjutan dan replikatif dalam penguatan kepedulian sosial di tingkat komunitas.

Abstract

This study aims to assess the influence of tidal fluctuations on the operational effectiveness of a sluice gate in the Petung River, Pasuruan. A quantitative approach was employed, combining hydrological analysis, tidal analysis, and hydraulic modeling using HEC-RAS under unsteady flow conditions. The dataset includes rainfall records, river discharge obtained from AWLR, and tidal data applied as the downstream boundary condition. Dependable discharge was determined using Q80% and Q95% probabilities, while tidal characteristics were analyzed to describe water level variability. The results indicate that the dependable discharge ranges from 0.548–0.730 m³/s (Q80%) and 0.416–0.526 m³/s (Q95%), reflecting limited flow during dry conditions. Tidal variation shows a considerable range, with maximum water levels reaching 2.80 m and minimum levels around 0.41 m, significantly affecting the river water profile. Hydraulic simulation reveals the occurrence of a backwater effect during high tide, leading to upstream water level rise and reduced flow capacity. The evaluation further indicates that sluice gate performance decreases during high tide due to downstream pressure, while flow conditions improve during low tide. Therefore, an adaptive operation strategy based on tidal patterns is required to enhance flow regulation and minimize flood risk.

Abstract

Poor maintenance of drainage channels in residential areas remains one of the main causes of water stagnation and potential flooding, particularly in rural regions. This condition is generally influenced by the low level of public understanding regarding the importance of routine drainage maintenance. This community service program aimed to improve residents’ understanding and awareness of drainage cleanliness in Janti Village, Waru District. The activity was conducted on November 8–9, 2025, involving 20 participants representing neighborhood associations (RT and RW). The implementation method applied an educational-participatory approach through several stages, including preliminary observation, preparation of educational materials, pre-test implementation, socialization sessions, interactive discussions, simple drainage cleaning practices, post-test, and activity evaluation. The evaluation instruments consisted of pre-test and post-test questionnaires analyzed using descriptive quantitative methods to measure participants’ improvement in understanding. The results showed an increase in the average participant understanding score from 30% before the activity to 70% after the socialization program. These findings indicate that the applied socialization method was effective in improving public knowledge regarding drainage functions, maintenance techniques, and the importance of community participation in maintaining environmental cleanliness. Furthermore, the activity encouraged community awareness to carry out sustainable drainage maintenance through collective community work and environmental participation. Therefore, this program has the potential to become a community service model that can be implemented in other areas facing similar problems.
