Blitar Regency is one of the strange culinary centers, among which are processed various foods from snail base ingredients, ranging from kripik, sate oseng-oseng and so on as well as the existence of Blitar district is one of the rice barns in East Java. With the existence of Blitar district as a snail-based culinary producer and one of the rice barns in East Java, this is not spared from several problems, such as the disposal of snail shells in the river and burning of rice straw in rice fields which both will cause environmental damage. This study aims to examine the use of snail shell ash and rice straw ash as a substitute material for cement in mortar mixtures against mortar compressive strength. The research method used was the experimental method by mixing fine aggregate main ingredients with snail shell ash and rice straw ash then testing the compressive strength. The results of the compressive test with the addition of the percentage of snail shell shell turned out to increase by 54.78%.

Abstract This research paper highlights the Rice Straw Ash (RSA) which is an agriculture wastage from rice cultivation and milling processes can be utilized in construction work. Compressive strength is increased due to replacement of rice straw ash up to 12.5% and also 10% cement replacing, it also increases the initial and final settlement time of mortar. By replacing of 10% RSA, the compressive strength is step by step increased and also by replacing the cement ratio the property of mortar (Water permeability) is depended and so as age of mortar. We can simply describe it that, by increasing age and compressive strength of mortar the permeability is decreased. Permeability of RSA mortar depends on the cement substitution percentage of RSA and age of mortar. When the permeability decreases, the compressive strength of mortar also increases.

Light brick waste is fragments or pieces of scrap leftover during the installation of lightweight bricks which are often allowed to pile up and becoming garbage in the surrounding area. The waste is difficult to recycle and has a very low selling value. This study aims to assess the compressive strength of mixed composition concrete specimens using lightweight brick waste on the quality of K-250 concrete aged 7 days as a mixture of fine aggregate concrete so that it becomes a product that has better-added value for the community. The research method used in this research is SNI for concrete based on data from literature and the test was carried out in the UNISLA laboratory. The results showed that the use of a 0% mixture of lightweight brick waste resulted in compressive strength of 21.78 Mpa, 3% mixture yielded compressive strength of 18.87 Mpa, 5% mixture yielded compressive strength of 24.39 Mpa, and 7% mixture yielded compressive strength of 26.00 Mpa.

This research aims to determine how to make bricks with additive Zeolite with a composition of 14%, 16%, 18%, and 20%. This research method using the experimental method, this research concludes that red bricks are added with additive Zeolite with variations in the addition of 14%, 16%, 18%, and 20%. 2 samples were made for each additional percentage of Zeolite Additive, with the mold size according to the fabrication length 21 cm x 10 cm x 5 cm. By going through the drying process for approximately 14 days and burning for approximately 3 days. The resulting increase in compressive strength even though some of the variants experienced a decrease. The addition of the red brick variant with a composition of 0% produces an average compressive strength of 30.95 kg / cm2 . The 14% variant produces an average compressive strength of 35.71 kg / cm2, the 16% variant produces an average compressive strength of 40.48 kg / cm2, 18% and 20% variants produces an average compressive strength of 33.33 kg / cm2. The highest increase in compressive strength is the 16% variant, with an average compressive strength value of 40.48 kg / cm2

This research uses stone ash waste from the stone crusher industry to preserve the environment. This material is an ingredient in making normal concrete. The use of stone ash as a substitute for sand is expected to increase the compressive strength in the planned slump and can optimize the use of rock ash waste to reduce environmental pollution that occurs. This study uses an experimental method with a total of 32 pieces of specimens. Each variation consists of 3 samples with a variety of fine aggregate levels of 40%, 44%, and 46%. The test object is a concrete cylinder with a diameter of 15 cm and a height of 30 cm. Test results for compressive strength at seven days for fine aggregate content variations of 40%: 22.25 Mpa; 44%: 24.30 Mpa; 46%: 17.08 MPa. Test results of compressive strength at the age of 14 days for variations in fine aggregate levels of 40%: 26.10 Mpa; 44%: 28.51 Mpa; 46%: 20.04 Mpa. Test results of compressive strength at the age of 21 days for fine aggregate content variations of 40%: 28.18 Mpa; 44%: 30.78 Mpa; 46%: 21.63 MPa. With these results, the Porous concrete produced can be used as preservation and maintain environmental protection. This product very cheap when compared to the original concrete, which calculated 22 U$ per square. The use of porous concrete has an impact on people's behavior that will preserve the environment, especially water content in the soil.

Cement is one of the main ingredients in the manufacture of concrete. The raw material is used in the manufacture of cement are limestone, silica sand, clay and iron sand. Cement is a material made of material that belong to natural resources that cannot be renewed, so that the raw material inventory of cement in nature is getting less. Continuous mining of cement raw materials has an impact on natural damage. It encourages the discovery of alternative materials as an additive to the manufacture of concrete. The method of data analysis begins with the investigation of cement material, coarse aggregate, fine aggregats and rice straw ash. Concrete is added with rice straw ash with variations of 0%, 5%, 10%, and 15% additions. The test specimen are cylinders with size ø 15 cm x 30 cm and the planned compressive strength is 14.5 MPa. After going through the treatment period for 7 days, the value of compressive strength is then correlated to the age of 28 days. Based on research that has been done at Civil Engineering Laboratory of Islamic University of Lamongan, it is found that there is a decrease of strength on each addition of ash straw content of paddy. Use of rice straw ash in concrete mix with variation of 0%, 5%, 10%, and 15% addition of The weight of cement has an impact on the decrease of concrete strength value. The compressive strength values obtained at the age of 28 days are 18,440 Mpa, 15,366 Mpa, 13,948 Mpa, and 12,530 Mpa.
