Abstract

TransJogja merupakan salah satu bus komuter dan moda alternatif utama yang secara resmi diperkenalkan oleh Dinas Perhubungan Daerah Istimewa Yogyakarta pada bulan Maret 2008. Moda alternatif ini diperkenalkan untuk mengurangi tingkat kemacetan yang terus meningkat, untuk mendorong penggunaan angkutan umum dan menyediakan lebih banyak alternatif moda bagi warga. Namun, Menurut PUSTRAL, persentase pengendara sepeda motor di Kota Yogyakarta mencapai 73,4% dari total modal share. Tidak dapat disangkal bahwa meningkatnya jumlah kendaraan pribadi dan rendahnya biaya bahan bakar telah berkontribusi pada pilihan moda di kota. Untuk meningkatkan minat masyarakat dalam menggunakan angkutan umum, maka perlu dilakukan pembenahan sistem jaringan pelayanan bus. Dalam penelitian ini, diusulkan dua alternatif perbaikan untuk mengatasi beberapa permasalahan pada jaringan. Saran tersebut diambil dari lesson-learned di Korea Selatan. Mendorong penggunaan angkutan umum diyakini sebagai cara yang efektif untuk meningkatkan kinerja jaringan. Saran tersebut diuji dengan menggunakan model simulasi lalu lintas makroskopik pada jalan di pusat perbelanjaan utama yaitu Malioboro. Hasil penelitian menunjukkan bahwa mendorong penggunaan angkutan umum dengan melarang penggunaan angkutan pribadi termasuk mobil dan sepeda motor dapat menurunkan penggunaan mobil pribadi dan pengemudi sepeda motor masing-masing hingga 2878 dan 3374 perjalanan per hari. Sedangkan pengendara sepeda dan TransJogja mengalami peningkatan masing-masing sekitar 1.389 dan 4.465 perjalanan per hari. Selain itu, saran untuk memulai reformasi sistem bus besar-besaran juga diusulkan. Di Korea Selatan, hampir 90% penduduk Seoul puas dengan reformasi tersebut. Kecepatan bus rata-rata telah meningkat, jumlah kecelakaan turun, dan pengguna angkutan bus bertambah hingga lebih dari 700.000 penumpang per tahun.

Abstract

Teknik pengukuran kualitas beton dapat dideteksi dengan mengetahui besarnya kecepatan perambatan gelombang ultrasonik. Dalam prosesnya, akurasi hasil pengukuran ditentukan oleh jarak transducer dan receiver, mutu material, impedansi akustik material, dan salah satunya homogenitas material. Hingga kini, metode yang populer digunakan adalah direct dan indirect untuk mengetahui kualitas material dan deteksi kerusakan pada beton. Salah satu kendala utama yang dihadapi adalah ketika kedua metode tersebut tidak dapat digunakan disebabkan kondisi eksisting Gedung. Skema uji semi-direct diusulkan untuk membantu menyelesaikan permasalahan yang tidak dapat dijangkau oleh metode direct dan indirect. Hasil akhir pengujian menunjukkan tingkat akurasi yang lebih rendah dibandingkan metode yang lainnya dengan selisih hasil pengujian 30%.

Abstract

The conceptual design stage is necessary because it is considered as a fundamental input in decision making for maximizing the performance of a building. On the other hand, to maximize the performance of the building, there are many things that need to be considered. Therefore, an estimation of the optimum dimensions and the reinforcement ratios of beam and column was carried out at the conceptual design stage using the artificial neural network (ANN). ANN is a network based method that allows to get an accurate approach even with the limited information provided. This study aims to help engineers shorten the time for trial at the conceptual design stage. A total of 36 building variations modelling were prepared as the training data for the set up ANN model. Eight parameters used which consist of earthquake accelarations, soil sites class, joint types, beam spans, number of storey, high of storey,  concrete strengths and diameters of the reinforcement. There are 16 empirical formulas for estimating the optimum dimensions and the reinforcement ratios of beam and column. The results showed that the dimensional regression values and the reinforcement ratio were 98.53% and 96.06% respectively. This value indicates that ANN can estimate well.

Abstract

Tsunami is not only caused by the strength of tectonic earthquakes with the dislocation of the seafloor, but also by landslides /rocks in shallow waters, or the relatively large fall of meteors/ celestial bodies. Unlike other tsunamis caused by slab collisions, tsunamis in the Sunda Strait tsunami caused by high tides and underwater landslides due to the eruption of krakatoa. Tsunami due to the eruption of Mount Anak Krakatau threatens at any time so that technology is needed to be able to help the community and BMKG monitor activities in the Sunda Strait so as to provide security and comfort of the surrounding residents. Therefore, research was made to measure the height of waves to detect high waves causing tsunamis in the Sunda Strait. In this research, Tsunami detection system using electrical circuits in its testing with submersible sensors as a wave height reader. The result of the sensor height readings read by the sensor in the process uses a Resberry-Pi microcontroller. The height limit set on the sensor produces siren sounds and sends short messages sent to residents of coastal communities of the Sunda Strait. The results showed that the tsunami detection system managed to read the water level in real time accurately according to the calibration equation. The water level reading tool set by the limit is 2 meters with the length of the wave using a maximum time of 90 seconds. The device will send a short message and produce a siren sound when the wave reaches a height of 2 meters for 90 seconds in a row. Sending messages takes 2-5 seconds, if there is a tsunami due to the eruption of Mount Anak Krakatau the evacuation time to the safe zone for coastal communities of the Sunda Strait is still affordable and safe.

Abstract

The convenience of pedestrian paths is an essential aspect that needs to be studied in urban planning. Along with the increasing use of motorized vehicles, facilities for pedestrians must also be considered to minimize the acquisition of pedestrian space. Walkability is a concept that prioritizes safety, comfort, and being able to provide friendliness to its users. The provision of facilities on pedestrian paths is also one of the supporting aspects in realizing a green city because the green lanes found on pedestrian paths have benefits such as circulation, city aesthetic functions, and maintaining urban air quality. The government area of Sleman Regency is an integrated office area that has begun to improve the pedestrian path, including Parasamya Street. This study aims to examine the application of the walkability principle on Parasamya Street, Sleman Regency, as an effort to support the concept of a green city. The research method used is qualitative through observation, documentation, mapping, and interpreting the results descriptively by comparing the existing conditions with theories and regulations related to the concept of pedestrian paths and the concept of a green city. The results obtained from this study are that the application of the walkability principles on Parasamya Street can support the concept of a green city which is indicated by the fulfilment of infrastructure facilities, including ecological comfort. Things that need to be improved are an equal distribution of facilities for the disabled and the improvement of crossing facilities.

Abstract

The results of the Eden Strategy Institute 2021 study show that Bandung City is ranked 28th in the world's Top 50 Smart City Government Rankings. However, from the results of the Asian Development Outlook 2019 study, Bandung City is ranked as the most congested city in Indonesia and 14th in Asia. Solutions to problems are offered in the form of Mobility as a Service (MaaS), an integrated system of transportation services, digitization, and the use of big data. The realization of MaaS requires contributions from all parties. The synergy between the government, academia, stakeholders, the media, and the public is called Pentahelix. The research stage includes the collection of primary data and secondary data by conducting a literature review. Then conduct a graphical analysis of multivariate data on Pentahelix with three assessments, namely performance, competence, and involvement. Next, modeling and loading were carried out for a pilot simulation of The Bandung City area in the eastern region using macro or meso-level traffic simulation software, namely PTV Visum 2022 (Student). After comparing with real-time analysis from the Google Maps application, comprehensive results were obtained with real conditions. As a means of controlling public transportation services, an Electronic Device Capture (EDC) hardware digital system is needed that is integrated between modes through software and artificial intelligence. The final stage of this study was carried out a risk analysis matrix for the implementation of MaaS for the city of Bandung with moderate risk results. MaaS is not a new idea, but it is a good solution to overcome congestion and change Bandung's transportation concept.
