Abstract

With the development of technology in the field of materials engineering, experts are working on existing problems in the field of construction. One of them uses eco-friendly waste as another alternative material and can be used as a substitute for cement in concrete mixes. The concrete mix produced is environmentally friendly as it uses industrial waste to completely replace cement. Concrete mixtures are known as geopolymers. . This geopolymer concrete can be formed from raw materials containing many silica and aluminum elements. These elements are found in many industrial wastes, including fly ash. And many other wastes in use today are not used as substitutes for fly ash, but as additives. One such waste is sawdust. Waste from mechanical or manual cutting of wood. The lumber industry inevitably produces wood waste in the form of sawdust and chips. One solution is to turn this waste into value-added products using simple technology. One of them is the mixture used to make geopolymer design

Abstract

Eggs are an almost perfect source of animal protein. Consumption of chicken eggs is a perfect food ingredient that contains high nutrients. Increasing the consumption of salted eggs can be done by making salted eggs in a wet way. In using wet media it is very easy to use water media which can be measured with certainty in adjusting the amount of salt content added. Salt levels are very influential in the results of these eggs later. Salt will enter the egg through the pores of the eggshell to the egg white, then to the egg yolk. The salt will draw out the water contained in the egg. through socialization activities on Making Salted Eggs with Water Media to Improve the Soft Skills of Pindrikan Lor Semarang Residents resulting in an understanding of making salted eggs with water media there was a significant increase from 20% to 67%, this shows that the service activities carried out were successful

Abstract

Plastic waste is the main problem of environmental pollution at SDN Gebang 1, an Adiwiyata school in Demak Regency. Piles of plastic waste need to be appropriately managed because they need to create a better impression of the vision and mission of the Adiwiyata School. Another problem was seen during the rainy season when plastic waste blocked the water flow. SDN Gebang 1 experienced flooding until the water entered the classrooms. One of the efforts made by the school is through collaboration with OISCA to make it a green school. However, schools still need help with waste handling in the school area. The program aims to utilize waste through Eco-Paving Blocks. The community service method includes five stages: socialization, training, application of technology, mentoring, and monitoring. The activities obtained results from using plastic waste in the elementary school environment, which was 100% because partners agreed that plastic waste must be managed well. Applying the TTG Eco-Paving Block tool is easy to use, with results of 85.25%. The successful implementation of the activity received a score of 90.50%. Partners can utilize 87.50% of plastic waste through the TTG Eco-Paving Block tool. The implementation of practical activities by teachers obtained results of 92.25%. Thus, teachers need assistance utilizing plastic waste through the TTG Eco-Paving Block tool, which helps reduce plastic waste at SDN Gebang 1.

Abstract

Abstrak- Jalan terdiri dari lapisan struktural yang berbeda, dimulai dengan lapisan pondasi agregat (Kelas A dan Kelas B), AC-BC, AC-WC, dll. Setiap lapisan struktural memiliki tugasnya masing-masing dan cara pelaksanaannya juga berbeda. Lapisan dasar material agregat merupakan lapisan struktur yang lebih tinggi dari permukaan tanah/bidang dasar yang bertugas menjamin daya dukung jalan agar permukaan jalan tetap stabil. Kerusakan aspal jalan sebagian besar disebabkan oleh lapisan dasar agregat yang tidak kuat dan tidak stabil. Proyek perkerasan jalan di jalan Pemuda Jepara perlu dilakukan karena ada pelebaran jalan. Pelebaran jalan dilakukan guna memperluas arus laju kendaraan agar mempermudah pengendara saat berkendara. Masalah yang dihadapi dalam proses pelebaran jalan Pemuda Jepara ini adanya ketidakseimbangan antara uji laboratorium dan uji lapangan. Oleh karena itu perlu adanya uji CBR agar menemukan data yang sesuai, dapat mengetahui nilai pemadatan sesuai aturan SNI. Hasil uji laboratorium dan lapangan sudahmencapai hasil stabilitas yang baik, akan tetapi antara uji laboratorium dan lapangan masih belum mencapai keseimbangan nilai, dimana uji laboratorium mencapai kategori baik dengan nilai CBR labotorium 99,75 %, sedangkan di lapangan mncapai keseimbangan yang kurang baik dengan nilai CBR lapangan 55,138%.

Abstract

In the area of highway Kelet - Bangsri area, Kelet Village, drainage problems and flooding often occur along the highway during the rainy season. From the problems found that there are no drainage channels as a result of residential construction that does not pay attention to the drainage function and can result in damage to road construction. This final project analyzes drainage channels with the aim of knowing alternative flood management. The results of the hydrological planning calculations will be used as the basis for hydraulic analysis, rainfall calculations using the isohyet method. The hydraulics analysis was carried out using the HEC-RAS and EPA SWMM programs. Based on the results of the analysis of existing conditions, it was found that inundation occurs because the capacity of the channel is not able to drain the flood discharge, such as the dimensions of the channel that are not suitable so that new planning is needed. The results of the analysis of the EPA SWMM software are more effective to be used as an alternative for handling the right flood problem according to the condition of the Kelet - Bangsri Highway, Kelet Village, Keling District, Jepara Regency with the planning of the new drainage channel dimensions of B = 0.6m and H = 0.8m.
