Pemanfaatan Limbah Cangkang Kerang sebagai Bahan Substitusi Agregat Halus pada Pembuatan Paving Block

Fadiya Syifa Amelia Putri — 2026-07-30

Paving block is one of the construction materials widely used as a surface covering and pavement material, such as sidewalks, residential roads, parks, yards, and parking areas. The increasing demand for paving blocks has led to higher use of sand as fine aggregate, which may contribute to excessive exploitation of natural resources. One alternative to reduce sand consumption is the utilization of shell waste as a partial substitute for fine aggregate. This article aims to examine the utilization of shell waste as a fine aggregate substitute in paving block production based on a literature review. The method used is qualitative with a literature review approach through content analysis of relevant previous studies. The results show that shell waste has potential as a fine aggregate substitute due to its hard texture, calcium carbonate content, and lime compounds that can support paving block characteristics. Several studies indicate that the use of shell waste in certain proportions can increase compressive strength, reduce water absorption, and still meet the requirements of SNI 03-0691-1996. However, excessive use of shell waste may reduce paving block quality because it affects density and particle bonding. Therefore, shell waste can be utilized as an environmentally friendly alternative material in paving block production with the appropriate mixture proportion.

Concrete block is one of the wall materials widely used in construction because it is relatively easy to produce, economical, and practical to install. The increasing demand for concrete blocks leads to higher consumption of sand as fine aggregate. Meanwhile, glass waste is an inorganic waste that is difficult to decompose naturally and may cause environmental pollution if not properly managed. This article aims to examine the utilization of glass waste as a substitute for fine aggregate in concrete blocks based on a literature review. The method used is qualitative with a Literature review approach through content analysis of relevant previous studies. The results show that glass waste has potential as a partial substitute for fine aggregate due to its silica content, hard texture, and particle size that can be adjusted to resemble sand. Several studies indicate that the use of glass waste in certain proportions can produce compressive strength that meets the design requirement and, in some cases, improves compressive strength. However, excessive use of glass waste may reduce concrete quality due to its smooth surface, non-absorptive behavior, and weak bonding with cement paste. Therefore, glass waste can be utilized as an environmentally friendly alternative material in concrete blocks, provided that the optimum proportion is considered and applicable construction material standards are followed.

Clean water is a basic need that determines public health, sanitation feasibility, and the sustainability of domestic activities. However, water quality may change due to geological conditions, seawater intrusion, domestic waste, agricultural activities, industrial activities, and distribution processes. This article aims to analyze clean water quality based on physical and chemical parameters through a literature review of previous studies. The method used is qualitative with a literature review approach through content analysis of scientific articles discussing groundwater, drinking water, spring water, rainwater, surface water, reservoirs, and dug well water. The physical parameters commonly used include temperature, turbidity, color, odor, taste, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), and electrical conductivity, while chemical parameters include pH, iron (Fe), manganese (Mn), chloride (Cl), nitrate, nitrite, hardness, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and selected metals. The review shows that most water sources in the selected studies still meet water quality standards for specific uses, especially for pH, temperature, TDS, and several heavy metals. Nevertheless, several studies indicate parameters requiring attention, such as Fe approaching the allowable limit, high turbidity, high chloride, BOD and COD exceeding standards, and low DO in waters under organic pollution pressure. Therefore, periodic analysis of physical and chemical parameters is essential to determine clean water feasibility, select appropriate treatment technologies, and prevent health risks and environmental degradation.

Wastewater management in sugar factories is an important part of water pollution cantrol because sugar production activities generate liquid waste from raw material washing, processing, cooling, and equipment cleaning. This wastewater may increase organic matter and suspended solids in receiving water bodies when it is discharged without adequate treatment. This article aims to examine the management of sugar factory industrial wastewater as an effort to prevent pollution in water bodies or rivers. The method used is descriptive qualitative research through a literature review approach with content analysis of relevant sources. The results show that pollution prevention needs to be carried out through identification of wastewater source, control of pollutant parameters such as BOD, COD, TSS, and pH, as well as the application of wastewater treatment plants, aeration ponds, adsorption, water quality monitoring, and continuous supervision of wastewater management.

Pemanfaatan Limbah Plastik Menjadi Bahan Campuran Pembuatan Aspal

Meningkatnya volume limbah plastik menjadi tantangan lingkungan global yang sangat serius karena sifatnya yang tidak dapat terurai secara hayati. Pada saat yang sama, sektor infrastruktur jalan membutuhkan inovasi berkelanjutan untuk menghasilkan perkerasan yang memiliki ketahanan tinggi terhadap beban lalu lintas dan perubahan kondisi cuaca. Penelitian ini bertujuan untuk mengevaluasi potensi dan efektivitas pemanfaatan berbagai jenis limbah plastik sebagai bahan tambahan atau bahan substitusi dalam campuran aspal panas melalui pendekatan tinjauan literatur secara komprehensif.

Metode penelitian dilakukan melalui analisis mendalam terhadap hasil-hasil eksperimen dari sepuluh artikel jurnal ilmiah terakreditasi yang membahas penerapan limbah polimer, meliputi Polyethylene Terephthalate (PET), Low Density Polyethylene (LDPE), Linear Low Density Polyethylene (LLDPE), Polystyrene (PS), serta limbah kantong plastik pada berbagai jenis campuran, yaitu AC-WC, AC-BC, HRS-WC, dan Porous Asphalt.

Hasil tinjauan menunjukkan bahwa integrasi limbah plastik secara signifikan meningkatkan karakteristik fisik aspal dan kinerja mekanis campuran. Parameter stabilitas Marshall menunjukkan peningkatan optimum pada rentang kadar plastik tertentu, yang berkorelasi dengan meningkatnya ketahanan terhadap deformasi permanen serta peningkatan nilai durabilitas sisa sesuai dengan spesifikasi teknis Bina Marga. Dengan demikian, pemanfaatan limbah plastik dalam campuran aspal memiliki potensi sebagai solusi inovatif dalam meningkatkan kinerja perkerasan jalan sekaligus mendukung upaya pengurangan permasalahan lingkungan akibat limbah plastik.
