KARAKTERISTIK PENGGUNA SEPEDA LIPAT TERHADAP PEMILIHAN MODA TRANSPORTASI DI KOTA PALEMBANG

Sustainable Transportation is one of the embodiment of sustainable development, sustainable development puts forward the concept of eco-friendly urban, where the concept aims to balance the increasingly rapid development activities with an eco- friendly transportation system that is integrated with other modes of transportation, particularly the public transportation. Through this research, it is expected that it will become a reference for planning the development of bicycle routes and lanes in the city of Palembang. The research method used was a quantitative descriptive approach, data collection techniques conducted through a questionnaire survey, the total population was 966 cyclists, the sample taken for respondents with the Slovin formula was 478 respondents. The sampling technique used was simple random sampling, the results of data processing will be illustrated in tables and diagrams and calculations for the study of bicycle route lane using a matrix of origin and destination. Based on the questionnaire data obtained, from the survey results of 478 respondents, the percentage of cyclist was predominantly male and it was 91%, based on the analysis of activity patterns of folding cyclists, it indicated that the use of bicycle was 77% and it intended to the purpose of sports trips, 8% was for the purpose of recreation, 6% was for the purpose of daily activities, 5% was for the purpose of social travel, and the last 4% was for work purposes. 20% of folding cyclists were aimed to the short trips ? 10 km, while the use of bicycles for medium distances, which was around 10 km to 40 km, with the largest percentages was 38% and 32%. 68% of folding cyclist stated that the bicycle mode was the most economical mode of transportation. Dealing with the analysis for the opportunity to develop special bicycle routes and lanes, bicycle users were enthusiastic to obtain supporting facilities in the form of special bicycle lanes, 97% of cyclists agreed that a special bicycle lane must be provided. The selection of roads for bicycle routes was based on the calculation of the origin and destination matrix for the cyclists, the districts of the most potential cyclists were selected as starting and ending points for the bicycle route. Thus, 2 alternatives were selected for the special bicycle route. Key Words: sustainable transportation, characteristics, bicycle route, bicycle lane

ANALISIS BIAYA DAN WAKTU BERDASARKAN ANALISA PRODUKSIVITAS ALAT BERAT PEKERJAAN TANAH GALIAN (PEMBUATAN PIT) PADA PROYEK INSTALASI PENGOLAHAN AIR LIMBAH

Technological advances provide opportunities for construction workers to use heavy equipment as a substitute for manual equipment. Heavy equipment can be a solution to increase the efficiency and effectiveness of work implementation, which can be seen in the cost calculation or unit price.It can be seen that alternative 3 uses 2 units of Kobelco PC-200 excavators, 4 units of 5 m3 dump trucks, these alternatives have the smallest time difference to the original conditions in the field. Therefore, it is very time efficient and fast to process and costs slightly increases and results in fast and efficient workmanship. It can be seen for the difference in costs of - 28,905,973 (- 26%) and the difference in total working time of -25 hours (- 40%). Referring to the description of the calculation of the comparison between the original conditions in the field with alternative calculations, if a minus (-) result is obtained then the work is faster. So it can be recommended to use alternative 3 to carry out soil removal work in the Wastewater Treatment Plant project. Palembang, South Sumatra.

PENGARUH PENAMBAHAN QUICKCURE CX TERHADAP UJI KUAT TEKAN BETON K-500

Quickcure CX is a chemical for concrete designed using the latest technological innovations, this added material can accelerate and increase the compressive strength of concrete by 5 - 10% and can reduce the moisture content in the concrete mixture by 5 - 10%. The purpose of this study was to increase and accelerate the effect of the compressive strength value of concrete produced by Quickcure CX added material on K-500 concrete.The research sample is a cube-shaped test object with a size of 15cmx15cmx15cm. There are 4 sample variations, namely: Normal Concrete, Normal Concrete + Quickcure cx 0.25%, Normal Concrete + Quickcure cx 0.45%, and Normal Concrete + Quickcure cx 0.65%, each variation consisting of 15 samples.After conducting the concrete compressive strength test, this study obtained the highest average compressive strength test results in Normal Concrete (503.2kg / cm2), Normal Concrete + Quickcure cx 0.25% (513.8kg / cm2), Normal Concrete + Quickcure 0.45% (536.4kg / cm2) and Normal Concrete + Quickcure cx 0.65% at 551.6kg / cm2 at the age of 28 days. So of the 4 variations in the value of the compressive strength test of concrete, it still increases in Normal Concrete + Quickcure cx 0.65%, and accelerating the concrete does not accelerate because the average age is 21 days with a variation of Normal Concrete + Quickcure cx 0.65% with a value of 488.8 kg / cm2 so the concrete has not reached the compressive strength that was planned.Keywords: Concrete, Quikcure CX, Compressive Strength, K-500

STUDI GERUSAN TANAH PADA LERENG SUNGAI LEMATANG DESA MUARA LAWAI KABUPATEN MUARA ENIM

Sungai Lematang memiliki panjang 244 km merupakan salah satu sungai terpanjang di Sumatera Selatan. Bantaran Sungai Lematang pun tak luput dari fenomena erosi. Dampak dari erosi ini dapat mengakibatkan gerusan pada lereng sungai. Oleh karena itu diperlukan penelitian penyebab terjadinya gerusan pada sungai tersebut, Penelitian dilakukan berdasarkan perhitungan kecepatan aliran sungai dengan metode apung, dan rumus Manning. Untuk stabilitas lereng menggunakan metode Fellenius. Hasil penelitian menunjukkan bahwa kecepatan aliran (Vlapangan) = 0,64 m/detik dan kecepatan aliran perhitunganVperhitungan= 0,61 meter/ detik > Vc dengan syarat batas terendah 0,60 m/detik, menunjukkan bahwa lereng di daerah tersebut mengalami penggerusan. Nilai stabilitas lereng sebesar 0,23 < 1,5 yang berarti lereng tidak stabil. Kata Kunci : Kecepatan aliran, gerusan lereng sungai.

PENGARUH PENAMBAHAN ABU SEKAM PADI PADA PEMBUATAN BATU BATA TERHADAP KUAT TEKANNYA

The use of bricks in the world of construction, both as structural and non-structural elements, cannot be replaced. This can be seen from the many construction projects that use bricks as walls in building and housing construction, fences, channels, and foundations. Bricks are made from a mixture of soil and water. In this study, the process of making bricks will be tried to mix the soil with the additional material of rice husk ash to determine the effect of changes in the mechanical properties of the bricks in terms of the shrinkage test and compressive strength test. The soil sample used is a type of clay soil originating from Suakarsa Village, Teluk Gelam District, Ogan Komering Ilir Regency. This study used a sample of block-shaped bricks with a length of 19.5 cm, a width of 9.5 cm, and a height of 9 cm. The variations in the composition of rice husk ash added were 0%, 3%, 4%, 5% and 6%. The addition of rice husk ash with a composition percentage of 3% to 6% can affect the mechanical properties of the bricks, namely reducing burnt losses and increasing the compressive strength of the bricks. The minimum burn value was achieved in the percentage of rice husk ash with a variation of 6%, namely by 37.55% burn loss. The optimum compressive strength value is achieved in the percentage of rice husk ash with a variation of 3% with 14 days of age, the compressive strength value is 76.88 Kg / cm².
