Abstract

Penelitian ini bertujuan untuk menentukan faktor-faktor yang berpengaruh signifikan terhadap kepemilikan sepeda motor di kota Kupang dan memprediksi besarnya peluang atau probabilitas suatu rumah tangga untuk memiliki satu, dua, dan lebih dari dua sepeda motor sebagai akibat dari perubahan kondisi karakteristik sosio-ekonomi mikro. Penelitian ini berbasis model multinomial logit (MNL) dengan metode maksimum likelihood. Berdasarkan kalibrasi hasil pemodelan, faktor yang berpengaruh signifikan terhadap kepemilikan sepeda motor di Kota Kupang adalah jumlah anggota keluarga, penghasilan, jumlah anggota keluarga yang bekerja, jumlah anggota keluarga yang sekolah, dan waktu tempuh ke sekolah. Perubahan ekstrim keselurahan faktor kepemilikan sepeda motor (nilai berubah dari 0 ke 0.50) akan meningkatkan probabilitas kepemilikan satu sepeda motor sebesar 43.90%, meningkatkan probabilitas kepemilikan dua sepeda motor sebesar 42.07% dan menurunkan probabilitas kepemilikan lebih dari dua sepeda motor sebesar 85.98% sebagai akibat dari kecenderungan untuk memiliki mobil pribadi. Pengembangan model ini telah memberikan indikasi pada tren yang diharapkan dari kepemilikan sepeda motor

Abstract

Generally, trip generation is based on activities from the household. Each household member, of course, has different travel destinations in a household, there will be several trips that are caused by the activity. This study is aimed at determining the factors that influence the trip generation and predict the magnitude of trip generation originating from residential areas based on activities in Kupang city. Travel activities were divided into three categories i.e. work activities, school activities and other activities. Data collection was done by distributing questionnaires to 444 households through random sampling technique. Based on the calibration of the modelling results with multinomial logit regression analysis, the factors that significantly influence trip generation from residential areas were the number of family members who did activities, the average distance travelled and the average travel time. The probability of trip generation was predicted to be 55.48% for work activities, 25.61% for school activities and 18.90% for other activities.

Abstract

This study is aimed to evaluate the quality of urban transportation service and its impact on passenger satisfaction and loyalty in Kupang city, NTT. Data collection was done by distributing questionnaires to 130 passengers chosen by applying random sampling technique. The survey results were analyzed by IPA method and CSI. Whereas, the relationship between importance, performance and passenger loyalty were analyzed using PLS. The results showed that the public transportation service has not reached satisfactory category with the value of CSI at 57,21% (very poor). The results of the analysis of PLS model revealed that both importance and performance positively affected on passenger loyalty, whereas importance negatively affected the performance.

Abstract

Pilihan kecepatan yang tidak sesuai sudah terbukti menjadi faktor utama penyebab kecelakaan lalu lintas, terutama pada segmen jalan berisiko seperti simpang tak bersinyal, jalan menurun dan lainnya. Sejumlah penelitian terdahulu telah melaporkan bahwa peluang kecelakaan pengendara sepeda motor di persimpangan prioritas dipengaruhi oleh tidak saja pilihan kecepatan saat memasuki area persimpangan dan kemampuan pengereman pengendara arus mayor namun juga pilihan celah penyeberangan kritis pengedara jalan minor. Studi ini bertujuan untuk menentukan peluang kecelakaan tipe tabrak belakang kendaraan yang berjalan beriringan di jalan mayor akibat pilihan celah penyeberangan kritis pengendara jalan minor. Untuk itu survei kecepatan dan jarak antar kendaraan serta celah penyeberangan kritis dilakukan dengan menggunakan kamera video. Selanjutnya, peluang kecelakaan tipe tabrak belakang disimulasikan berdasarkan perbedaan kemampuan pengereman pengendara sepeda motor yang diperoleh dari hasil penelitian terkait terdahulu. Diketahui bahwa hampir tidak terdapat perbedaan kecepatan antara kendaraan yang berjalan beriringan sehingga dari hasil simulasi terindikasi kuat bahwa peluang tabrak belakang sangat ditentukan oleh perbedaan kemampuan pengereman pengendara. Hal itu berarti bahwa diperlukan upaya terstruktur dan sistematis untuk memperbaiki kemampuan pengereman pengemudi dan perilaku berkeselamatan di jalan. Kata kunci: batas kecepatan, kemampuan pengereman, tabrak belakang

Abstract

IDENTIFICATION OF DAMAGE AND RECOMMENDATION OF SMALL FARM WATER RESERVOIR IMPROVEMENT IN KUPANG CITY, NUSA TENGGARA TIMUR PROVINCE. The condition of small farm water reservoir that exist today in Kupang has faced a lof of the decrease of service levels due to the effective age factor, sedimentation factor, effectiveness and the damage construction factor. This can eventually interfere the demand for water needs of people in Kupang. Therefore, the existence of facilities and infrastructure of water resources, especially permanent small farm water reservoir in particular, is absolutely necessary and to be maintained. Generally, the problem of small farm water reservoir is a functional degradation characterized by the reduction of capacity of accommodated water, sedimentation, blogging, a wild plantin the body of the weir or embankment, erosion, and some other problems. In order to overcome the problem of fulfillmentof water needs that continue to increase in various purposes, it is necessary to return the function of supply of water resources especially farm water reservoir and optimize the development of water resources potentials in accordance with the priority and ability of existing funds. The purpose of this community service are to identify the existing condition building and to compiled a review of damage identification results and recommend the repairmen of small farm water reservoir.
