Abstract

Abstract. Mortar is made from a mixture of sand, cement and water. In order to obtain good extrude results for the application of 3D printing technology, in this research, mortar was added with admixture materials. There are two types of admixture in mortar, those are chemical admixture and pozzolan admixture. The highest compressive strength was obtained from Mortar+Pozzolan of 37.5 MPa, while the best flowtable and the best results from the extrude of 3D printing machine was Mortar+Chemical+Pozzolan. Keywords: mortar, extrude, chemical, pozzolan

Abstract

Jati Raya Street is one of the streets in Banyumanik district, Semarang, where many vehicles pass. Before the Covid-19 pandemic, the traffic jam usually occurs at certain hours because of people activities passing through this street. The purpose of this research is to know the degree of saturation and the street level of service from the volume / capacity ratio during New Normal condition on Covid-19 pandemic. The primary data survey is by measuring the street width and counting the two-way traffic volume. The survey was held on Monday, 9 November 2020, at 06.15 – 08.15, 11.05 – 13.05, and 16.05 – 17.05. From the survey results, the maximum traffic flow is 784 pcu/hour, the time is at 07.15 – 08.15, and the traffic direction is from Pasar Jati toward Sukun Raya street. The street capacity is 2371 pcu/hour, with a 0,33 degree of saturation. The street level of service based on this survey is B, which means, steady traffic flow, the driver has enough option to control the vehicle speed. This research was done during New Normal condition on Covid-19 pandemic, where there is a decrease on the number of vehicles that passing through this street, for some reasons, which one of them is because the school activities is using an online methods, so that students can study from home, without the needs of parents taking them to school and picking them up from school.Keywords: capacity, degree of saturation, level of service

Abstract

Lack of water availability for agricultural land during the dry season results in less optimal agricultural productivity, This is what happened in Troso Lor village, Pecangaan sub-district, Jepara Regency. In order to meet water needs continuously and maintain the availability of water sources, efforts are needed in the framework of protecting, developing, controlling and utilizing water resources.  For this reason, a construction plan for the Jeruk Gulung Dam on the Jeruk Gulung River will be planned as an effort to utilize water sources for irrigation in the Troso village area, Pecangaan sub-district, Jepara regency.  Meanwhile, the results of the analysis of irrigation water requirements are used for channel hydrological analysis. After planning the weir construction, the weir stability control is carried out against rolling, shear, eccentricity and soil bearing capacity . Meanwhile, the results of the analysis of irrigation water requirements are used for channel hydrological analysis. After planning the weir construction, the weir stability control is carried out against rolling, shear, eccentricity and soil bearing. Based on the results of the analysis and planning of the Jeruk Gulung Dam, the data obtained for the area of rice fields is 16 Ha with a requirement of 0.019 m3 / s of irrigation water with a fixed weir type with 100.1347 m3 / sec flood discharge. The width of the weir is 19.2 m with an effective width of 17.7 m and a width of 1 m for rinsing.

Abstract

In formulating the seismic design criteria for a building at ground level or determining the amplification of the peak earthquake acceleration from the bedrock to the ground for a site, the site must be classified first. Site class assignment must be carried out through field and laboratory soil investigations. Site Class consists of SA (hard rock), SB (rock), SC (medium soil), SE (soft soil) and SF (special soil). SNI 1726: 2019 with various classes of SB, SC, SD and SE sites. From the analysis results, it is found that the variation of soil site classes has an effect on the area of minimum reinforcement requirements, except for the logitudinal reinforcement requirements of the lower support beam for site class variations, the value is fixed. The variation of soil site classes has a significant effect on the area requirements of the longitudinal reinforcement in the column. The largest requirement for column longitudinal reinforcement is Soft Soil Site Class (E) and the smallest requirement is Rock Site Class (B).

Abstract

Home industry for making alcohol traditional in Bekonang Village, Sukoharjo produces large volumes of liquid waste which is discharged into the river without going through any waste treatment. One of the wastewater treatment methods is Multi Soil Layering Electrolysis (MSLE) which is a combination of Multi Soil Layering (MSL) and Electrolysis methods used to reduce levels of Total Suspanded Solid (TSS) and Nitrate in Alcohol waste. The purpose of this experiment was to determine the effect of time and voltage variations and the effectiveness of using the Multi Soil Layering Electrolysis (MSLE) method to reduce traditional alcohol waste. The results showed that MSLE method is quite effective to reduce Nitrate levels by 82.06% with an effective voltage of 10 volts in 40 minutes. Meanwhile, for TSS levels increase until 164 mg/L with the voltage is 10 volts in 30 minutes.
