Abstract

KRL memiliki banyak keunggulan seperti tarif yang murah, bebas dari kemacetan dan juga memerlukan waktu yang relatif cepat untuk mencapai tujuan. Namun sayangnya, jumlah penumpang yang terus bertambah tidak dapat diimbangi dengan peningkatan fasilitas pelayanan. Hal ini menyebabkan adanya keluhan terhadap keamanan dan kenyamanan yang diterima oleh para pengguna KRL. Tujuan penelitian ini adalah untuk mengetahui tingkat kepuasan penumpang terhadap kualitas pelayanan Stasiun Citayam berdasarkan Peraturan Menteri No. PM 63 Tahun 2019 Tentang Standar Pelayanan Minimum Angkutan Orang Dengan Kereta Api dan untuk mengetahui atribut penting yang perlu ditingkatkan pada kualitas pelayanan Stasiun Citayam berdasarkan hasil analisis dengan metode IPA (Importance Performance Analysis). Penelitian ini diharapkan dapat memberikan manfaat bagi PT. KAI dalam hal ini khususnya yaitu kepada operator KRL yaitu PT. KCI dalam hal upaya peningkatan fasilitas dan kualitas pelayanan pada Stasiun Citayam serta sebagai bahan masukan dalam menganalisis Standar Pelayanan Minimum angkutan orang dengan Kereta Api. Pada penelitian ini, metode yang digunakan yaitu dengan teknik survei kuisioner baik secara online maupun offline untuk mendapatkan preferensi penumpang terhadap tingkat kinerja dan tingkat kepuasan pada atribut pelayanan. Hasil analisis menghasilkan rata – rata tingkat kepuasan penumpang terhadap kinerja pelayanan berdasarkan Peraturan Menteri No. PM 63 Tahun 2019 Tentang Standar Pelayanan Minimum Angkutan Orang Dengan Kereta Api di Stasiun Citayam adalah sebesar (-0,35). Tingkat kepuasan dengan nilai negatif menunjukkan bahwa pelayanan yang diberikan belum memenuhi harapan penumpang. Dengan analisis Importance Performance Analysis (IPA) didapatkan atribut pelayanan yang perlu ditingkatkan di Stasiun Citayam dengan skala prioritas utama adalah (1) Informasi gangguan keamanan (2) Toilet bersih, terawat, tidak licin & bau (3) Mushola, tempat wudhu bersih, terawat.

Abstract

AbstractJakarta, the capital of Indonesia, undertook a major change of the transportation system, digitization of the transportation system was initiated by implementing a cashless payment system on the Commuter line in Jabodetabek, followed by implementing BRT with Busway mode, then MRT and LRT all of them are also cashless. All-digitization and application-based transportation systems force people to change. This is a trouble for senior citizens and is alleged to be one of the factors that causes them to be reluctant to switch to public transportation.This study analyzes the hypothesis that the reluctance of people of late adulthood to late elderly to use public transportation is due to the difficulty in understanding the digitalization system that is applied and because of the low level of respondents' trust in digital systems in public transportation. The study was conducted by distributing closed questionnaires to respondents who are Jabodetabek (Jakarta-Bogor-Depok-Tangerang-Bekasi) residents aged 45 years to 65 years who still have a fairly high activity, data tabulated then performed regression analysis. Key words: transportation system 4.0 era, transportation digitization, elderly transportation ­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­AbstrakDaerah Khusus Ibu Kota Jakarta, ibu kota Indonesia, melakukan perombakan besar pada sistem transportasi, digitalisasi pada sistem transportasi diawali dengan menerapkan sistem pembayaran tanpa uang tunai (cashless) pada Commuter line di Jabodetabek, disusul dengan mengimplementasi BRT dengan moda Busway, kemudian MRT dan LRT yang semuanya juga cashless. Sistem transportasi yang serba didigitalisasi serta berorientasi pada aplikasi memaksa masyarakat untuk berubah. Hal ini merepotkan bagi warga senior dan disinyalir menjadi salah satu faktor yang menyebabkan mereka enggan untuk beralih ke transportasi publik.Penelitian ini menganalisa menguji hipotesa bahwa keengganan masyarakat usia dewasa akhir hingga lansia akhir untuk menggunakan transportasi umum adalah karena kesulitan memahami sistem digitalisasi yang diterapkan dan karena rendahnya tingkat kepercayaan responden terhadap sistem digital pada transportasi umum. Penelitian dilakukan dengan menyebarkan kuesioner tertutup kepada responden yang merupakan warga jabodetabek berusia 45 tahun hingga 65 tahun yang masih mempunyai aktivitas yang cukup tinggi data ditabulasi kemudian dilakukan analisa statistik dengan SPSS.Kata kunci: sistem transportasi era 4.0, sistem transportasi, digitalisasi transportasi.

Abstract

Indonesia have not finished yet with the overloading truck problem which makes early failure in Indonesia pavements, mainly in national highways such as Pantura national highway. This is the first research which the aim is to compare the Cumulative Equivalent Single Axle Load (CESA) between 4 policy conditions; (1) zero overloading policy enforced; (2) modified 1 zero overloading policy enforced with 40% legal overloading tolerance for the nine-daily needs (rice, sugar, cooking oil, soy beans, salt, meat, chicken, eggs, onion), portland cement and fertilizer trucks; (3) modified 2 zero overloading policy enforced with 50% legal overloading tolerance for the same transporter as point (3); (4) no policy. This modification of the policy considered to avoid the price increment of those goods caused by the rising expedition cost. The Liddle’s formula used with k–factor = 1 for single axles, 0.086 and 0.031 for tandem and tridem axles. The finding of the study shows decreasing CESA between the alternatives compare to no policy applied. Application of policy 2 and 3 reduce the CESA number as much 44% and 34% respectively, there is 10% displaced cargo difference between policy 2 and 3 which must be loaded to other vehicles

Abstract

Minimnya ruang untuk resapan air di kota-kota besar seperti Jakarta, menimbulkan genangan-genangan, oleh sebab itu perlu antisipasi genangan air hujan, salah satunya adalah pembuatan Lubang Resapan Biopori (LRB). Metode alternatif Lubang Resapan Biopori (LRB) dipilih dikarenakan memiliki beberapa keunggulan diantaranya teknik pembuatannya mudah, operasinya sederhana, biaya yang dibutuhkan murah dan dapat dilakukan secara gotong royong.  Selain berfungsi untuk meningkatkan luasan resapan air, keunggulan dari penerapan metode ini adalah pemanfaatan limbah organik yang dapat dikonversi menjadi pupuk kompos yang dapat dimanfaatkan oleh masyarakat. Kegiatan PkM ini dilaksanakan pada Rabu, 24 April 2024 di RPTRA Meruya Selatan yang dihadiri oleh 55 peserta termasuk Lurah Meruya Selatan. Berdasarkan hasil perhitungan skor kepentingan dan kinerja, peserta merasa sangat puas dengan materi yang disampaikan, karena sesuai dengan kebutuhan.

Abstract

The development of road and transportation infrastructure in Tangerang Regency is crucial for economic growth. The increasing number of vehicles on Jalan Raya Serpong-Cisauk, without adequate infrastructure development, has led to traffic volumes exceeding capacity. The solution implemented to reduce queue length and delays is the construction of a flyover. This study employs quantitative and qualitative methods, with primary data including traffic volume, free flow speed, and side friction, while secondary data is sourced from relevant agencies. The analysis is conducted using PKJI, VISSIM, and SWOT methods. The results show an increase in road capacity after the construction of the Cisauk flyover, with a decrease in the Dj ratio from 2.38 to below 1.00, and improved LOS from F to C/B during holidays and D/C on weekdays. However, surrounding businesses experienced negative impacts, including revenue decline and business relocations.

Abstract

C75 cold rolled steel is a material used in building construction with a lighter weight compared to conventional steel. One important aspect in the design of C75 light steel is the connection, where the connection must be designed safely so it is very important to maintain the structural integrity of the building and ensure the safety of building users. The aim of the research is to obtain the correct formulation for the C75 mild steel connection type in relation to the thickness of the C75 cold rolled steel. The method used is to create a connection system in the form of a variety of connections consisting of connections using screws only, combined screws and bolts, and connections using rivet nails. Overall, from the test results, it was found that the use of mild steel connections with a modified model between screws and bolts produced a greater value compared to using rivet connection tools alone or screws alone, this happened the same for every thickness of mild steel tested, both thickness 0, 65 mm, 0.75 mm or 1.00 mm. The greatest results were found in the connection of 4 screws and 1 bolt at a mild steel thickness of 1.00 to 100.00 N with a deflection of 2.58 mm. When compared with rivets, the increase reached 42.50%, while compared with screws, there was an increase of 20.00%. So rivet connections are brittle compared to screws and screw and bolt connections are a more ductile connection, so they can be recommended as connections in light steel. It's just that mild steel which has a greater thickness tends not to cause buckling compared to mild steel which is much thinner, where buckling is likely to occur in the mild steel material.
