Studi Kebutuhan Angkutan Umum Penumpang Perkotaan di Kota Palu (Studi Kasus: Trayek Mamboro - Manonda)

One of cause of public transport services is not optimal is the incompatibility between the number ofpublic transport with passenger numbers to be served. Incompatibility of the number of publictransport with the number of passengers served would also affect the income of public transportoperators. The purpose of this study is to estimate the needs of the urban public transport routesMamboro – Manonda, Palu City based on the number of passengers along the route. Primary datacollection survey was conducted in January of 2010 for 3 days at each peak morning, afternoon andevening. Survey of primary data through questionnaires and enumeration of the number ofpassengers. The primary data include the number of passengers up and down along the route, roundtrip time of the public transport, time headway of each the public transport. Secondary data includepath of Mamboro – Manonda route, the number of public transportation of Mamboro – Manondaroute. Methods and standards used in estimating the number of public transportation refer to theTechnical Guidelines for the delivery of the Urban Passenger Transport, 2002, the Ministry ofTransportation, Republic of Indonesia.The results have been found several conclusions as follows: there are differences in the needs ofpublic transport in every peak hour morning, afternoon and evening, number of public transport thatoperates not according to the number of passengers served, increasing the number of publictransport is not required for the next few years

Penggunaan Metode Pavement Condition Index (PCI) dan Present Serviceability Index (PSI) dalam Penilaian Kerusakan Jalan di Kota Palu (Studi Kasus : Jalan Karanja Lembah, Kota Palu)

Street of Karanja Lembah is a provincial road linking Palu City and Sigi Regency. After a visual survey, the road has suffered a lot of damage, especially on its surface. The purpose of this study was to determine the pavement condition values based on the Pavement Condition Index (PCI) method and the Present Serviceability Index (PSI) method, as well as to determine the type of road handling based on the PCI and PSI values obtained on these roads. The PCI method is carried out directly by dividing the road into several segments called segment units, then recording the type of damage, the dimensions of the damage, and the severity of the damage for each type of damage. In research using the PSI method, the PSI value was calculated using IRI (International Roughness Index) data obtained from the Highways Service of Central Sulawesi Province. From the results of the analysis, it was obtained that the average PCI value for Jalan Karaja Lembah was 79.95% with a "very good" pavement condition, while the average PSI value for Jalan Karaja Lembah was 2.13% with a pavement condition "moderate". For the right type of handling for the PSI and PCI methods, namely the type of periodic maintenance

Studi Penggunaan Kapur sebagai Bahan Aditif terhadap Karakteristik Campuran Beton Aspal Lapis Aus (Ac-wc)

Asphalt Concrete Wearing Course (AC-WC) is the layer indirect contact with the wheels of the vehicle that makes this layer is easy damage. The use of additive in Asphalt Concrete Mixtures as AC-WC has often done to improve the durability. One of additional material that has been used is hydrate lime. The aim of this research was to know the effect of using lime as additive on AC-WC characteristics.Variations lime used in this study was 0%, 5%, 10%, 15%, 20%, 25% respectively. Characteristic of AC-WC mixture include stability, flexibility, durability, VIM, VMA, VFB and flow of the mixtures. Test characteristic of the mixtures using Marshall Method.Analysis of the relationships the characteristic of AC-WC mixtures with variations of lime using statistical methods is experiment factorial at 95% confidence level or α= 5%. The result of this study was to found that using lime as additives to effect the characteristic of AC-WC mixtures. Optimum Asphalt Content tends to increase due to increased lime content in the AC-WC. The result also found that the best lime content is 15%, Optimum asphalt content is 6.67% with an increase stability value of 9.75%, durability value of 1.39% and flexibility value of 11.61% when compared to the characteristics of AC-WC mixture without additives lime

Kajian Ketersediaan dan Kebutuhan Air Baku dengan Pemodelan Ihacres di Daerah Aliran Sungai Tapung Kiri

The demand of raw water in Kampar Districts is increasing in step with population growth. At this time, the water supply system is regulated by PDAM Tirta Kampar what still have problem to service coverage. Especially Tapung Sub-District has not been served. Therefore, the existence of the Tapung Kiri River is expected to be a solution to overcome these problems. Thisstudy use IHACRES for rainfall - runoff modeling, which in the calibration stage reach Nash- Sutcliffe effectiveness value of 0.630. Overall, this model provides an understanding that thesuccess obtained on the calibration stage does not guarantee success in the verification stage. Analysis of water availability is done to analyze the realable discharge river (Q90%) based onaverage annual the discharge resulting realable discharge occurred in 2000. The greatest realable discharge occured in October amounted to 93.75 m3/sec, and the smallest in Maretamounted to 43,69 m3/sec. Analysis of water demand is forecasted to the population growth of up to 22 years and produce raw water demand total with forecasts early of the year (2013) of 0.109 m3/sec and the end forecasts of the year (2035) of 0.264 m3/sec

Survei Penilaian Pembelajaran Keterampilan PJOK Pada Masa Pasca Pandemi Covid-19 Di SMP Laboratorium Universitas Negeri Malang

Penelitian ini memiliki tujuan untuk mengetahui bagaimana penilaian keterampilan PJOK di SMP Laboratorium Universitas Negeri Malang setelah pergantian model pembelajaran yang sebelumnya dilakukan secara daring kembali lagi ke pembelajaran yang dilakukan secara luring atau tatap muka. Menurut hasil observasi yang dilakukan oleh peneliti pada saat KPL pada pembelajaran Pendidikan jasmani, olahraga dan Kesehatan di SMP Laboratorium Universitas Negeri Malang ditemui masalah yaitu kurangnya kesesuaian pengambilan nilai pendidikan jasmani dan hasil belajar siswa yang ideal karena imbas dari masa pandemi covid-19 dan masa pasca pandemi covid-19. Penelitian ini termasuk dalam penelitian deskriptif dengan pendekatan deskriptif kuantitatif. Metode penelitian yang digunakan merupakan metode survei dengan jumlah responden sebanyak 103 responden (101 siswa kelas VIII dan IX, serta 2 guru) di SMP Laboratorium Universitas Negeri Malang. Instrumen yang digunakan merupakan lembar kuesioner dengan total 36 butir pertanyaan yang nantinya data yang diperoleh akan dianalisis menggunakan Skala Guttman. Hasil penelitian ini menunjukkan bahwa perolehan total skor pada sub indikator Bola Besar, Bola kecil, Atletik, Beladiri, Senam lantai, dan kebugaran jasmani memiliki persentase sebesar 54,4% dan masuk di dalam kategori cukup baik. Sehingga dapat disimpulkan bahwa terdapat peningkatan terhadap penilaian keterampilan siswa meskipun belum sepenuhnya optimal dan perlu adanya perhatian khusus terhadap siswa agar siswa dapat beradaptasi dengan maksimal
