Abstract

Beton ringan adalah beton yang memiliki densitas lebih kecil dari beton pada umumnya. Padapenelitian ini, telah dihasilkan suatu beton ringan yang menggunakan bola plastik sebagaiagregat kasar. Pengujian terhadap beton agregat bola plastik (BP) dilakukan melalui uji kuatpantul dan uji kuat tekan. Penelitian dilakukan di Laboratorium Teknik Sipil UniversitasMalikussaleh. Benda uji dibuat sebanyak 12 buah berbentuk silender 15 cm x 30 cm, bolaplastik digunakan berdiameter 6 mm. Pada perencanaan campuran beton, agregat kasardigantikan dengan bola plastik sebesar 25%, 50%, dan 100% pada perbandingan volume. Fasyang digunakan 0.48, dengan bahan pengikat: semen Andalas type I. Dari hasil pengujiandiperoleh: untuk kuat pantul beton normal (BN) didapat 32,43 Mpa, untuk kuat pantul betonringan 25% (BP1) didapat 24,39 Mpa, untuk kuat pantul beton ringan 50% (BP2) didapat 22,61Mpa, dan untuk kuat pantul beton ringan 100% (BP3) didapat 20,56 Mpa. Sedangkan hasilpengujian kuat tekan untuk sampel BN didapat 24,72 Mpa, dan untuk sampel BP1, BP2, BP3,didapat hasil kuat tekan masing-masing 17,17 Mpa, 14,91 Mpa, 12,08 Mpa. Hasil nilai kuatpantul dan kuat tekan beton BP menunjukkan penurunanan yang signifikan dari pada nilai kuatpantul dan tekan beton normal. Sedangkan densitas kuat tekan beton BP juga menunjukkanpenurunan yang signifikan dari pada densitas kuat tekan beton normal. Hubungan nilai kuatpantul dan kuat tekan beton dapat dinyatakan dengan persamaan: untuk sampel BN, y =1.4402x - 3.1672, ( R2= 0.9595), untuk sampel BP1, y = 4.677x - 55.926, ( R2= 0.9874), untuksampel BP2, y = 0.2182x + 19.36, ( R2= 0.9839), dan untuk sampel BP3, y = 0.7412x + 11.509, (R2= 0.592). Selanjutnya beton dengan sampel BP1 dan BP2 tidak dapat dikategori sebagaibeton ringan, karena densitasnya masing-masing sebesar 2380 kg/m3 dan 2144 kg/m3.Sedangkan beton dengan BP3 dapat di kategorikan sebagai beton ringan, BP3 mempunyaidensitasnya 1724 kg/m3. Dengan demikian agregat bola plastik berpotensi sebagai agregatuntuk pembuatan beton ringan dengan mutu 12 Mpa. Kelas mutu tersebut tergolong kedalambeton ringan non struktural.

Abstract

Keutapang Village is located in Nisam District, North Aceh Regency, Aceh Province with a village area of 123.4 ha. This village has 120 ha of agricultural land and rice as the main commodity, but the productivity of the planting season and harvest cannot be maximized due to the lack of irrigation that has been built, thus it is necessary to increase the effectiveness of irrigation management by mapping irrigation as information for village irrigation development planning. The rural irrigation map contains information on the location, situation and condition of irrigation, and the priority scale for improving the WEBGIS-based network. The purpose of this community service activity was to produce a village irrigation network map and educate village officials in increasing the effectiveness of irrigation network management through WEBGIS-based mapping. The mapping stages included measurement surveys using GPS, digitizing the surface of the area through Google Earth, depicting the layout with the AutoCAD application and making maps with QGIS/ArcGIS software. This community service activity in Keutapang Village, Nisam District produced informative and attractive village irrigation geospatial maps. The result of this activity is a digital irrigation map whose printout is submitted to the village officials. It is hoped that this map can be published and used as a basis for future sustainable village development planning.

Abstract

Solid waste management is a significant urban issue in Indonesia. This is exacerbated by rapid population growth and urbanization, which are not accompanied by sound waste management practices, such as a lack of infrastructure and widespread illegal dumping. This paper presents a data-driven methodology for analyzing trash generation patterns and identifying infrastructure requirements using a Geographic Information System (GIS). The goal is to create a data-driven strategy for identifying optimum Waste Collection Locations (WCPs) in order to improve service efficiency and reduce environmental impact. The study results show that Lhokseumawe City produces 530 m³ of waste daily. Therefore, Lhokseumawe City requires 44 strategically located waste disposal sites, taking into account existing illegal dumping locations and population density. An additional 21 garbage trucks are also needed to manage the urban waste generation volume. This indicates a significant shortage of waste management facilities to serve the population. This study presents a practical plan for local governments, including optimal WCP locations and designs, to achieve the SDGs goal of becoming a sustainable city.

Abstract

Liquefaction is a natural phenomenon that occurs when previously sandy soil turns into mush as a result of an earthquake and has the potential to become a natural disaster if not anticipated early. the coastal zone of Dewantara District is included in the earthquake-prone area (referring to the results of previous studies, the value of the seismic vulnerability index is between 0.41 to 18.3 Kg, with the potential for damage caused to be medium and high risk) because most of the area is an area that has alluvial plains a wide beach and located on a tectonic route so that it is estimated that there is a potential follow-up threat after an earthquake occurs, in the form of liquefaction. Determination of the distribution of liquefaction potential due to earthquakes is determined based on data obtained from microtremor measurements. The specific objective of this study is to provide information regarding the potential and vulnerability of liquefaction to Policy Makers/Local Governments in evaluating plotting areas and/or preparing regional spatial plans based on disaster risk reduction/mitigation aspects. Based on the results of the processed data analysis, several important conclusions can be identified in this study. The character of soil vulnerability is related to the value of dominant frequency (f0), soil amplification (A0), and seismic vulnerability index (seismic vulnerability index). This relationship can be used to formulate whether an area has the potential to experience lateral ground motion (liquefaction) which potentially can affect the coastal area of ​​Dewantara District. Based on microseismic data analysis (standard deviation), several disaster-prone zone points were obtained in the north and east of the measurement point. In detail, this is shown by the map of the distribution of SVI values ​​in the Coastal Area which is in the range of 20-100, especially in the north it is at a value above 75, which allows for a higher chance of liquefaction on the condition that there are major earthquakes accompanied by with rock pores filled with fluid.

Abstract

Cow feces on roads causes damage to asphalt on highways because cow feces contains a large amount of nutrients. The use of Styrofoam in asphalt is expected to improve the technical properties of a mixture. This study aims to determine the Marshall characteristics of asphalt concrete (AC-WC) mixtures with 5%, 7%, and 9% Styrofoam waste additions in 60/70 asphalt against asphalt weight with cow feces immersion for 30 minutes, 24 hours, and 48 hours. The best stability value was obtained with a 5% Styrofoam substitution, which was 1972.55 kg. The parameters for mixtures with and without Styrofoam, including stability, flow, MQ, density, VIM, VMA, and VFA, still meet the specifications of the 2018 Bina Marga standards. The durability value without substitution was 92.64% with ordinary water immersion and 90.80% with cow feces immersion. The durability value with varying Styrofoam percentages 5% was 95.56% and met the specifications set by Bina Marga in 2018, which is ≥ 90%.
