Penggunaan Abu Bonggol Jagung Sebagai Pengganti Filler Dalam Komposisi Campuran Aspal AC-WC

Campuran aspal dapat dimodifikasi dengan menambahkan berbagai jenis bahan, seperti bahan kimia, bahan alami, atau limbah industri. Penelitian ini bertujuan untuk mengevaluasi pengaruh substitusi filler dari limbah abu bonggol jagung pada campuran AC-WC melalui pengujian Marshall. Variasi kadar aspal yang digunakan adalah 5,5% dan 6%, dengan kadar abu bonggol jagung sebesar 1%, 2%, dan 3%. Hasil uji Marshall menunjukkan bahwa substitusi abu bonggol jagung memberikan hasil tertinggi pada setiap karakteristik sebagai berikut: stabilitas 935,72 kg pada kadar abu 3% dengan kadar aspal 6%, flow 4,63 mm pada kadar abu 2% dengan kadar aspal 6%, VMA 19,94% pada kadar abu 1% dengan kadar aspal 6%, VIM 4,63% pada kadar abu 2% dengan kadar aspal 6%, VFB 81,75% pada kadar abu 3% dengan kadar aspal 6%, dan Marshall Quotient sebesar 280,69 kg/mm pada kadar abu 2% dengan kadar aspal 6%. Berdasarkan hasil pengujian ini, dapat disimpulkan bahwa penggunaan abu bonggol jagung sebagai filler pada variasi kadar 1%, 2%, dan 3% masih sesuai dengan standar Spesifikasi Umum Bina Marga 2018 Revisi 2.

Sustainable Self-Compacting Concrete: The Role of Limestone Powder as A Cement Replacement

The excessive use of cement in concrete production contributes significantly to environmental impacts, particularly CO? emissions. One potential solution is the partial replacement of cement with limestone powder in self-compacting concrete (SCC). This study aimed to investigate the effect of limestone powder as a partial cement replacement on the fresh properties and compressive strength of SCC. Limestone powder was used at replacement levels of 0%, 6%, 9%, 12%, and 15% by weight of cement. The fresh properties of SCC were evaluated using slump flow, V-funnel, and L-box tests, while compressive strength tests were conducted to assess hardened performance. The results showed that SCC mixtures containing up to 9% limestone powder satisfied the SCC workability requirements. The optimum performance was achieved at 6% limestone powder replacement, which produced a slump flow diameter of 600 mm and compressive strength of 29.58 MPa, exceeding the design strength target of 25 MPa. Higher replacement levels reduced both workability and compressive strength, with the 15% mixture failing to meet acceptable performance criteria. These findings indicate that limestone powder can be effectively utilized as a sustainable partial cement replacement in SCC at moderate replacement levels while maintaining satisfactory fresh and hardened properties.

FACTORS AFFECTING WASTE MANAGEMENT IN NORTH BUNTULIA VILLAGE, POHUWATO DISTRICT

The fact remains that waste management is still not given proper attention and is inadequately handled by various parties, despite being a shared responsibility. Improper waste management can lead to numerous environmental issues such as flooding, global warming, and the outbreak of various diseases. This article aims to identify and describe the factors influencing waste management in North Buntulia Village, Pohuwato District. The research method employed is qualitative, utilizing an interactive model analysis for data analysis. This model consists of three components: 1) Data reduction, 2) Data presentation, and 3) Data verification and conclusion drawing. The findings indicate that the factors influencing waste management include: 1) the size of the organization, 2) management style, 3) the complexity of the business environment, 4) the production process, and 5) the characteristics of the problems faced and the objectives of planning. This study recommends that the Regional Government of Pohuwato Regency.

TINJAUAN KARAKTERISTIK MARSHALL DENGAN PENGGANTIAN SEBAGIAN PASIR PADA LAPIS AUS AC-WC MENGGUNAKAN BOTTOM ASH

Pemakaian batu bara sebagai sumber energi menghasilkan residu berupa bottom ash yang menimbulkan pencemaran lingkungan. Penelitian ini menggunakan metode penelitian experimental di laboratorium yang bertujuan untuk meneliti efek penggunaan bottom ash sebagai pengganti agregat halus terhadap stabilitas, kelelehan, ronggaudara, rongga didalam agregat dan Marshall quotient dari campuran aspal beton. Penelitian ini menggunakan 50 benda uji yang terbagi kedalam 5 persentase penggantian agregat halus dengan bottom ash yakni 0%,5%,10%,15% dan 20% dengan kadar aspal 5,5%. Â Dari hasil penelitian ini didapatkan bahwa semua variasi memenuhi spek pengujian sesuai pada bina marga 2010 refisi III dengan persentase terbaik penggantian agregat halus dengan bottom ash adalah 10%.
