Gerusan tebing sungai merupakan salah satu permasalahan yang mengancam kestabilan tebing sungai, gerusan ini banyak menimbulkan kerugian yang berdampak terhadap keberlangsungan lahan yang ada disekitar sungai, tidak sedikit perkebunan dan perumahan warga yang tinggal di pinggir sungai. Desa Alue Buloh, merupakan salah satu desa yang terletak di pinggir sungai Krueng Ineung Daerah Aliran sungai (DAS) Krueng Seunagan merupakan salah satu desa yang berada di Kabupaten Nagan Raya yang terhubung dengan jembatan ke desa Latong, terjadinya gerusan dasar sungai dan gerusan lokal yang sudah sangat mengkhawatirkan. Gerusan tebing sungai merupakan hal yang sangat mengancam bagi lahan yang ada disepanjang sungai tersebut, jika dibiarkan gerusan tersebut dapat terus menerus mengikis lahan penduduk, Pengabdian ini dilakukan untuk memberikan ilmu pengetahuan kepada masyarakat metode yang relative mudah dan ramah lingkungan dalam usaha melindungi tebing sungai dari ancaman gerusan oleh aliran air sungai tersebut, pelatihan dikemas dengan kegiatan sosialisasi dimana dalam kegiatan ini masyarakat/mitra diberikan materi dan cara pembibitan serta penanaman langsung rumput vetiver yang menjadi tumbuhan yang akan membantu mengurangi dampak gerusan tersebut. Luaran yang dicapai dalam pengabdian ini adalah peningkatan kapasitas kelompok masyarakat dalam hal penanggulangan erosi tebing sungai secara vegetative dan melakukan pembibitan vetiver dan penanaman langsung pada pinggir sungai.
The quality of the road depends on the pavement, drainage conditions, and materials. For this reason, it is necessary to make innovations in improving the quality of road pavement, one of which is increasing the material. There are many types of pavements, one of which is porous asphalt pavement. Porous asphalt has many cavities that is easy for water to pass but has a low stability value with high permeability. This research will utilize Low Density Poly Ethylene (LDPE), as an additive, CPO, and Pen 60/70 in a porous asphalt mixture. The purpose of this study was to determine the characteristics of the porous asphalt mixture by substituting LDPE and CPO for Pen 60/70. The method used in analyzing the characteristics of the porous asphalt mixture refers to the specifications of the Australis Asphalt Pavement Association (AAPA) (2014), with parameters Camtabro Loss (CL), Asphalt Flow Down (AFD), VIM, stability and flow. The gradation used in this study is an open gradation. This research was started from determining the value of Optimum Asphalt Content (KAO), with two variations, namely Variation 1 (1% LDPE, 10% CPO, 89% pen 60/70), variation 2 (5% LDPE, 10% CPO, 85% Pens 60/70). The KAO value of variation 1 is 5.03% and the second variation is 4.75%. After obtaining the KAO value, LDPE and CPO are substituted. The test results for the porous asphalt mixture for CL values were 34.12% and 27.07%, respectively; AFD value of 0.13% and 0.12%; for the VIM value of 14.90% and 19.03%; stability value 603.24 kg and 603.19 kg; and flow values are 5.03 mm and 4.80 mm. In general, the value obtained from the test meets the required requirements. However, the durability value of the mixture did not meet the requirements, namely 60.15% and 48.22%, with the condition >90%.
The planning of the Air Pinang - Ujung Batee road reconstruction project, Tapaktuan - Pasie Raja District, South Aceh Regency is a step to meet road comfort, efficiency and also increase road users. The importance of the review as part of the evaluation and supervision as well as a source of data for other researchers in order to support the smooth and fast transportation and economy as well as increase the ease of access for the community, especially in the Air Pinang area. In this research method, the researcher uses qualitative methods, where this research starts from data collection, where in this study primary data is used, namely data obtained from respondents through interviews, direct observation, while secondary data is obtained from journals, articles and also from relevant company data. The results of the analysis show that the process of carrying out the work is good, starting with preparing the road body and then laying it compacted using a vebrator roller, after the compaction process is complete, the binder absorption layer is carried out, namely liquid asphalt is sprayed with asphalt sprayer.
The Susoh irrigation area is one of the irrigation areas in Sounthwest Aceh Regency, the Susoh Irrigation Area irrigates water with a standartd area of 5,793 Ha and a functional area of 2,571.24 Ha. However, with damage along the channel, the water needs are less than optimal for irrigating water in the rice fields. Damage to one of the irrigation buildings will affect the performance of the existing system, so in the secondary canal of the Susoh Irrigation Area it is necessary to do a research on channel damage analysis. Water discharge, water loss is also the amount of efficiency and effectiveness in the Susoh Irrigation Area. From the results of the analysis, it is known that the amount of water loss in the secondary canal in the Susoh Irrigation Area is 0.15696 m/s, the efficiency value is 77.67257% and the effectiveness value is only 51.79%. From the result of this analysis, it can be seen that the condition of the D.I Susoh secondary canal is mostly damaged, so it needs rehabilitation.
