Abstract

Permasalahan lalu lintas dapat dijumpai dari berbagai faktor, salah satunya pertumbuhan sarana, prasarana, dan fasilitas transportasi. Simpang Empat Bersinyal Jalan Magelang Kilometer 5 dan Jalan Selokan Mataram merupakan persimpangan yang terkena dampak dari peningkatan volume kendaraan. Pedoman Kapasitas Jalan Indonesia 2023 (PKJI, 2023) menjadi acuan untuk memandu pengerjaan, lalu dilakukan permodelan menggunakan Software PTV Vissim. Hasil penelitian ini meninjau kondisi eksiting, dan dengan alternatif yang efisien untuk kinerja simpang bersinyal. Pada penelitian ini menghasilkan nilai derajat kejenuhan, peluang antrian, dan tundaan.

Abstract

Mount Merak area in Imogiri Bantul Regency, Yogyakarta Special Region, is a highly important historical and cultural site. Its existence is located on a hillside with a terraced topography, making it vulnerable to the impact of hydrometeorological events (such as extreme rain). The aim of this research is to measure and analyze the intensity of rain in the Mount Merak Imogiri area. Provide data-based recommendations for hydrometeorologicaldisaster mitigation strategies, especially related to drainage management and erosion prevention. The methodology used involves frequency analysis of maximum daily rainfall data for 20 years (2004–2023) from the Siluk Rain Post which was processed using MS Excel software. The selection of the best distribution model was based on the Chi-Square and Smirnov- Kolmogorov goodness-of-fit tests, which determined the Log-Normal distribution as the most suitable method. Results of calculating rain intensity using the Mononobe method taking into account the concentration time (Tc) of 4.91 minutes. The analysis results show that the rainfall intensity value for return periods 2, 5, 10, 20, 50 and 100 years respectively is 15.71; 19.40; 21.66; 23.73; 24.37; and 26.29 mm/hour. These findings indicate a high risk of surface runoff in a short duration, so it is necessary to design optimal drainage systems and strengthen slopes to maintain the stability of cultural heritage building structures from the threat of local erosion and flooding.

Abstract

A study was conducted to examine the impact of circuit training on basketball shooting skills among the athletes of Suryakancana University basketball club. The research utilized a experimental design, allowing for a close resemblance to a real experiment. The objective was to test the effect of the independent variable (circuit training) on the dependent variables (shooting skills) and establish a cause- and-effect relationship. The experimental group received the circuit training treatment, while the control group did not. The study involved a population of Suryakancana University basketball club athletes, with a sample size of 20 out of 40 individuals. Results of the research revealed that the 14 week circuit training program had a significant impact on improving shooting skills, as indicated by the N-Gain Score of 0.89, which exceeded the threshold of 0.7. Particularly, the training enhanced arm strength and leg muscle strength among the athletes.

Abstract

Penelitian ini bertujuan untuk menentukan prioritas pengelolaan dan penanganan fasilitas 27 sekolah dasar negeri di Kota Yogyakarta berdasarkan kondisi fisik, jumlah siswa, lokasi, dan aksesibilitas. Metode Analytical Hierarchy Process (AHP) digunakan untuk menentukan bobot kriteria dan subkriteria melalui perbandingan berpasangan berdasarkan skala Saaty. Data diperoleh melalui kuesioner yang melibatkan 28 responden yang terdiri atas pihak Dinas Pendidikan dan pengelola sekolah. Hasil analisis menunjukkan bahwa kondisi sekolah menjadi kriteria dengan prioritas tertinggi sebesar 39,19%, diikuti aksesibilitas sebesar 22,40%, jumlah siswa sebesar 21,16%, dan lokasi sebesar 17,25%. Pada tingkat subkriteria, prioritas tertinggi terdapat pada kerusakan ringan (39,66%), sekolah dengan jumlah siswa lebih dari 500 siswa (37,54%), lokasi pinggir jalan kota (42,23%), dan aksesibilitas melalui bus kota (33,73%). Hasil pengujian konsistensi menunjukkan seluruh nilai Consistency Ratio (CR) < 0,10, sehingga penilaian dinyatakan konsisten. Hasil penelitian dapat menjadi dasar pendukung bagi Pemerintah Kota Yogyakarta dalam menetapkan prioritas pemeliharaan dan peningkatan fasilitas sekolah secara lebih sistematis, objektif, dan terarah.
