Abstract

Soil stability is an attempt of improvement carried out to increase soil carrying capacity in order to fulfill the needs of construction. The improvement method used in this study is mixing rice husk ash (RHA) with a certain percentage of clay soil. The tests carried out in this study include soil physical properties, compaction and CBR testing. Based on CBR testing, the results obtained were 11.65% on the variation of 0% RHA, 5% for RHA at 20.39%, 10% for RHA at 10.92% and for RHA 15% at 3.56%. The highest increase in CBR value occurred at the addition of RHA 5% which was 74.96% compared to the original soil of CBR. Based on the test results, it can be seen that the addition of waste rice husk ash with a level of 5% which is most effectively used in an effort to increase the landfill carrying capacity so that it can be functioned as a material for landfill stabilizer for subgrade roads

Abstract

Tanah ekspansif adalah tanah yang kandungan lempungnya memiliki potensi kembang susut akibat perubahan kadar air. Kondisi jalan pada ruas jalan Ie Mirah-Lama Muda (Kabupaten Aceh Barat Daya) mengalami hal yang sama, yaitu cepat mengalami kerusakan meskipun sering dilakukan perbaikan pada lapisan permukaan (surfase). Tujuan dari penelitian ini adalah untuk mengetahui apakah fly ash yang berasal dari PLTU Nagan Raya layak dijadikan bahan stabilisasi untuk proyek-proyek jalan pada tanah ekspansif khususnya ruas jalan lintas barat Aceh. Metode yang dilakukan adalah dengan melakukan stabilisasi tanah dengan menambah Fly Ash dan melakukan pengujian di Laboratorium Pengujian yang dilakukan adalah analisis kadar air, analisis saringan, analisis berat jenis, pengujian batas attenberg, analisis CBR dan pemadatan standar proctor. Hasil dari uji laboratorium menunjukkan adanya penurunan berat jenis sampel tanah disebabkan karena tanah distabilisasi dengan fly ash yang memiliki berat jenis yang lebih kecil. Hasil dari penambahan Fly Ash menurunkan kadar air dalam campuran tanah. Hal ini sangat menguntungkan dalam proses stabilisasi karena potensi pengembangan tanah semakin berkurang. Hasil test Attenberg menunjukkan penambahan Fly Ash 20% mampu menurunkan nilai indeks plastisitas dari 28,61% menjadi 2,88%. Hal ini terjadi karena penambahan Fly Ash menyebabkan terjadinya ikatan antar partikel dan tertutupnya sebagian pori-pori tanah sehingga tanah menjadi kurang sensitif terhadap perubahan kadar air. Penambahan Fly Ash meningkatkan berat isi kering karena terjadi perubahan distribusi butiran halus menjadi tanah berbutir kasar sesuai banyaknya penambahan Fly Ash. Penambahan fly Ash 20% memberikan peningkatan yang cukup signifikan dengan nilai CBR sebesar 15,7% dibandingkan daya dukung tanah asli yang hanya memiliki nilai CBR 3.4% dan tergolong tanah yang jelek. Fly Ash yang berasal dari PLTU Nagan Raya layak untuk dijadikan bahan stabilisasi tanah dalam pelaksanaan konstruksi khususnya jalan raya yaitu sebagai subbase course

Abstract

The balance between availability and demand for water is an important factor determining the productivity of a plant. Imbalance between water availability and water demand can reduce productivity or even crop failure. The main water source that irrigates the Pandrah Irrigation Area comes from the Krueng Pandrah River located in Bireuen Regency, Aceh Province. The Krueng Pandrah watershed has a total area of about 127.24 km2 and has a main river length of 44.37 km. This study aims to determine the amount of irrigation water needed by plants and the available water discharge to meet crop water needs so as to improve the quality of community harvests, especially in Pandrah District, Bireuen Regency. In this study, the calculation of water requirements was carried out using Cropwat version 8.0 software. Cropwat software is an FAO program that is very practical to use to determine the value of plant water needs and irrigation water needs. In determining the 80% reliable discharge, the FJ Mock method is used as a reference to calculate the value of water availability. To find out the value of the water balance between the two, a water balance analysis was carried out. From the research results, it is known that the maximum water demand is 1,694 m3/sec and the minimum water requirement is 1,238 m3/sec. As for the available water to meet the water needs of plants, it is known that the maximum mainstay discharge is 3.46 m3/sec and the minimum reliable discharge is 2.27 m3/sec. From the results obtained and after analyzing the water balance, it is known that the Krueng Pandrah watershed is in a condition of surplus water. Where the water needed by plants can be met properly by available water without deficit during planting. The value between water demand and the availability of existing water has reached a waterbalance so as to avoid crop failure for the community in the Pandrah irrigation area, Bireuen Regency.

Abstract

Waste glass constitutes significant landfill waste, leading to environmental concerns. Considering its chemical composition, glass powder contains 50% to 60% silica, making it suitable for construction materials. Consequently, this community service initiative introduced waste glass as a building material, serving as a partial substitute for sand in construction products. In addition, the activity involved teaching partners how to create castings/road gates utilizing waste glass. The target partners in this activity were productive business groups engaged in selling wind holes, well rings, rosters, and similar products. The approach applied involved socialization and hands-on practices at the partner's premises. The program's success was obtained through interviews and product compressive strength tests with the partners. The outcomes demonstrate the partners' keen interest in the activity, their understanding of the benefits of utilizing waste glass as a partial sand replacement, and their ability to create products. Notably, the compressive strength of the products created with the partners ranged from 24.72 MPa to 30.84 MPa, aligning with the SNI 03-2442-1991 standard for road curbs (30 MPa). The activity positively impacted the partners, enhancing their business prospects and contributing to environmental sustainability. The training helps in enhancing the partners' skills and capabilities.
