Abstract

The main issue in the implementation of precast concrete systems lies in the connections. The connections in precast systems must possess the strength to withstand the occurring loads. One of the methods used for connecting precast concrete is the dry connection method. To test the connections of precast beam-columns, a quasi-cyclic loading test is utilized, which generates data on the relationship between load (P) and displacement (∆). The test results indicate that test specimens using 4 anchors have a higher maximum capacity compared to those using 2 anchors. Additionally, the cycles that occur in the test specimen with 2 anchors are longer than those in the specimens with 4 anchors and monolithic specimens. The peak load is achieved by the test specimen with 4 anchors, reaching 1488 kg at a displacement of 18 mm, specifically at a 2% drift. Both the monolithic and 4-anchor test specimens have the same drift, reaching 2%. However, the longest cycles occur in the test specimens with 2 anchors, reaching a 4% drift. Consequently, it can be concluded that the test specimens with 4 anchors have a greater capacity and shorter cycles compared to those using 2 anchors and the monolithic specimens.

Abstract

The high sales of cosmetic products in the world are not directly proportional to the good quality of cosmetic products. The The Food and Drug Administration (BPOM) declared, from October 2021 to August 2022 as many as 1 million pieces of cosmetic products contain Pigment Red 53, Rhodamine B, and Sudan III which are hazardous and prohibited ingredients. This study aims to disseminate information on case reports and toxicity of Pigment Red 53, Rhodamine B, and Sudan III contamination in Indonesian cosmetics. The study used a descriptive method with a case report study design. The study used secondary data, namely a list of cosmetic products containing Pigment Red 53, Rhodamine B, and Sudan III obtained from the website of the Indonesian authorities through the BPOM. Data collection was carried out on 4-5 October 2022. The BPOM declared 16 cosmetic products from 5 incorporated containing Pigment Red 53, Rhodamine B, and Sudan III. Undoubtedly, BPOM reported cases of Pigment Red 53, Rhodamin B, and Sudan III contamination still occurring from October 2021 to August 2022. The existence of these dyes should not be used as a mixture of cosmetics and personal care. In line with dangerous toxicity, these dyes are mutagenic, genotoxic, and carcinogenic. The BPOM must work even harder in its efforts to monitor safe cosmetic products to protect the health of the Indonesian people.

Abstract

Perintis Kemerdekaan road is a connecting road for people who will use the Bridge of Kapuas and  Landak. The government has realized the addition of a new bridge construction as a duplicate which is located right next to the Landak Bridge. The Landak II Bridge was completed in April 2019 and has been operating in August 2019. People still cannot feel comfortable in using traffic. The construction of the Landak II parallel bridge has not solved the problem of increasing the volume of vehicles in Pontianak. Because of these transportation problems, the researchers tried to analyze the performance of the Perintis Kemerdekaan road. The purposes of this researches are (1) to determine the changes in the performance of the road section used for traffic flow on the Perintis Kemerdekaan road in 2022 after the operation of the Landak II Bridge. (2) Provide an overview of the recommendations for handling impacts that are carried out to overcome road performance problems. The research method used is descriptive and quantitative methods. The results showed that the level of service for the Perintis Kemerdekaan road after the Landak II bridge was built was at level E where the current was unstable and the speed sometimes stopped.

Abstract

Liquefaction is a decrease in the shear strength of the soil caused by an increase in pore water pressure until it is equal to the strength value of the soil. The Plaxis 2D application with the UBC3D-PLM model is used in this study to analyze the effect of the magnitude moment on soils with liquefaction potential, the effect of the magnitude moment on the increase in pore water pressure ratio, the effect of different soil densities, and the effect of the depth of loose soil on the potential for liquefaction. The effect of moment magnitude on liquefaction potential is obtained from the results of data modeling analysis. The analysis results show that the potential for liquefaction increases with the magnitude of the moment. On the other hand, the liquefaction probability is lower when the moment magnitude is smaller. This study shows that an earthquake with a magnitude of 6.95 (Mw) occurs in loose and medium-dense soils. Meanwhile, an earthquake with a moment magnitude of 5.5 (Mw) only occurs on soils with loose density. Meanwhile, the earthquake with a moment magnitude of 4.27 (Mw) did not experience liquefaction at any soil density.

Abstract

AbstractMineral mining activities will leave waste rock known as tailings, which has small particle sizes and can trigger an oxidation reaction of the sulfide minerals contained therein and produce AMD. Laboratory tests have been carried out to determine the effect of the additional lime in terms of rate and particle size to neutralize the acid water formed through qualitative and quantitative mineral testing and static geochemical testing for various combinations of lime rates and sizes. This study used lime with a CaO content of 90.9% and tailings with a sulfur content of 4.88%. Subsequently, the pasta pH-EC, ABA, and NAG tests were conducted on a mixture of lime and tailings with lime sizes ranging from 8-16 to 50-100 mesh and a lime: tailings ratio of 2.5 to 15 kg/ton tailings. The test results show lime with a size of 50–100 mesh with a lime: tailings composition of 15 kg/ton tailings provides the most optimal effect in neutralizing potential acidity from tailings indicated by a pH value of 7.18. This study is expected to provide input in the management of tailings in mining to avoid acidic water which has the potential to dissolve metal content in tailings that have a negative impact.Keywords: AMD, lime content, grain size, Ph, tailing

Abstract

Industrial activities have led to the aquatic environment degradation. One of the pollutants is lead (Pb) which has a dangerous toxic effect, cannot be decomposed and is mutagenic. High levels of Pb in waters can result in the death of aquatic biota and pose a threat to human health. This study examined the ability of the Jeringau plant (Acorus calamus) to absorb Pb. The Jeringau plant is taken from the river bank, with a length of 20 cm, has many leaves and roots. Artificial Pb waste was made with various concentrations of 0.5 mg/L, 1 mg/L and 2 mg/L. Furthermore, the Jeringau plant was put into a reactor containing Pb waste and observed for 9 days. The obtained results showed that Pb concentration decreased at the ninth day of 0.03 mg/L, 0.067 mg/L and 0.201 mg/L.
