Abstract

The rubber plant (Hevea brasiliensis Muell. Arg) is an important plantation crop in Indonesia because it is one of the non-oil and gas products that are a source of large amounts of foreign exchange income for the country. Experiment was arranged in a Randomized Block Design with one factor, namely Compost for Wastewater Treatment Plant (WWTP) sludge from a rubber factory which consisted of 5 treatment levels. Statistical analysis was carried out using variance (ANOVA). Variables observed in rubber plants were an increase in bud grafting length, plant diameter, the number of leaves, shoot dry weight, and root dry weight. The results showed that the WWTP waste compost from the rubber factory affected the growth of rubber seedlings, as shown in the variable length of grafting shoots, the number of leaf stalks (strands), and the dry weight of the plant crown. Meanwhile, the increase in stem diameter and dry weight of plant roots showed no significant effect on the observed variables.

Abstract

The purpose of this research is to see how the role of the Change.org website and how the Change.org account interacts with Twitter social media accounts through mentions that are used to increase public awareness of the environment. This study uses qualitative research, which uses Q-DAS (Qualitative Data Analysis Software) to analyze the data using Nvivo 12 Plus and Vosviewer software. The results of this study indicate that Change.org, in voicing environmental cleanliness, uses social media as a media campaign. The social media used by Change.org itself is Twitter. The change.org Twitter account is one of the largest environmental petitions; the form petition carried out by Change.org is by calling on @Cocacola @McDonalds and BurgerKing, which contains various petitions to find solutions for plastic bottles, which many say are choking the environment. The ability of online petitions to facilitate requests for change in public policies and connect the public with policymakers shows that online petitions can increase individual and group political participation. The existence of a petition on the @Change.org Account can gradually save the environment.

Abstract

Noise is associated with a risk factor for several cardiovascular diseases, one of which is hypertension. Hypertension is estimated to cause 7,5 million deaths, or about 12.8% worldwide. The textile industry is exposed to high noise intensity because it constantly uses machines. The results of a preliminary study of noise measurement showed that the average at 6 points reached 90 dBA. The Threshold Value for the noise level contained in permitted government regulation is ≤ 85 dBA for duration of exposure of 8 hours. The measurement results exceed the threshold value. This study was analytical observational research with a Cross-sectional study design. The sample in this study was 74 workers textile industry in Semarang city. The average noise intensity measurement in the entire machine area of spinning unit 5 of the Semarang City Textile Industry is 87.49 dBA. Based on statistical test analysis, the results of noise levels (p-value = 0.037), working period (p-value = 0.015), and continuity of use of ear protection equipment (p-value = 0.048) and duration of exposure per day (p-value 0.510) were obtained. There is a significant relationship between noise level, working period, and continuity of Ear Protection Equipment use with the incidence of hypertension.

Abstract

Mosques need water in sufficient quantities for ablution, usually the mosques use surface water from PDAM services and well water. Surface water and ground water have decreased in quantity and quality, so it is necessary to find alternative sources of water to meet the clean water demand. On the other hand, the potential for rainwater is neglected, rainwater that falls is left to flow. Pontianak is one of the cities crossed by the equator which has high rainfall, the method of harvesting rainwater is appropriate in the tropics. This research was located on campus mosque at Engineering Faculty of Tanjungpura University. The purpose of this study was to determine the water demand in mosque and identify the potential for rainwater to meet the clean water demand in mosque. The method used in this research is field survey to calculate the water demand and interview with the mosque management to obtain supporting data. Based on the calculation, the total of water demand in mosque is 60 m3/month or 2 m3/day, while the volume of rainwater in campus mosque at Engineering Faculty of Tanjungpura University is 61.258 m3/day, and the potential volume of rainwater each month can meet the clean water demand.

Abstract

Noise is unwanted sound at a particular time and is sourced from any source. Data from the Pusarpedal Laboratory and the Ministry of Environment and Forestry of the Republic of Indonesia show that railroad settlements' noise in Yogyakarta, Surabaya, Semarang, and Bandung is beyond quality standards. Tambakrejo Village, Gayamsari District, Semarang, one of the railroad settlements at JPL 05 Kaligawe Street, Semarang area, close to a railroad. This research aims to know the noise level of the settlements. The sampling of noise level is done for 24 hours by measuring the noise for each time interval, with a total of 16 measuring points for 4 areas with various distances, 2.5 m, 5 m, 10 m, and 15 m. The sampling result shows that the railroad settlements have a noise level rate of 91.8 dB at a distance of 2.5 m, 89.5 dB at 5 m, 85.2 dB at 10 m, and 81.5 dB at 15 m. According to NOISE REL regulation, the maximum noise level allowed is 85.57 dB during 421 minutes or 7.02-hour of exposure. This sampling result shows that the noise levels are beyond of quality standards of both NIOSH REL and PermenLH No. 48/1996.

Abstract

Radin Inten II International Airport is the largest airport in Lampung Province which in 2019 underwent a status change to become an international airport. This article tries to present changes in the acoustic environment caused by flight activities around the airport. Noise measurements were carried out at 12 sampling points in the range of 300-4000 m and under the flight path, which then calculated the noise level (Leq) and the WECPNL index. Contour mapping of noise exposure uses an overlay technique visualized with contour lines. Leq measurement results are 60.4-81.4 dBA with an average value of 69.8 dBA. The distance of the sampling point to the runway is known to have a negative correlation with the noise level, while the noise measured on weekdays and weekends has no difference. The mapping results show that the most affected zones are dense settlements about 600 m from the runway. Three locations are known to fall into the noise level 3 zone, and two other sites fall into the noise level 1 and 2 zones. The non-noise zone is within a 2.5 km distance from the runway. The reduced comfort of living due to noise is a consequence of the economic improvement that may be felt by the people living around the airport.

Abstract

One of the supporting facilities for operational activities at the Tanjung Perak Port is the existence of adequate green open spaces. The type of plant that is widely planted is the Angsana tree. Since 2018, this port has had an innovation to reuse waste from trimming activities to become compost, but the results are not optimal because there is still a lot of compost in the form of whole leaves. In this research, the composting method will be tested using Black Soldier Fly larvae and local microorganisms from banana hump. Compost material in the form of the waste of Angsana leaves is mixed with the waste of mackerel fish which comes from processing activities of mackerel fish food. Variations were made with different feeding regimes for Black Soldier Fly larvae, namely 3 weekly, daily, and weekly with dose of local microorganism banana hump as much as 15 mL/kg. The results of composting showed that the variations of feeding regime have significant effect for compost quality.

Abstract

Most of the wastewater from the textile industry in Indonesia has a negative impact on the environment and society. The wastewater contains heavy metals such as lead (Pb) and total chromium (Cr-Tot) from the coloring process. Pb and Cr-Tot parameters testing usually use Atomic Absorption Spectrophotometer (AAS). The purpose of this study was to compare between the calibration and the addition method to test the metal parameters of Pb and Cr-Tot contained in wastewater of textile industry of PT. X. Calibration method is often use for heavy metal concentration test than addition method. However calibration method is not frequently used for low concentration while addition method can be used for that. The difference between two methods is in the procedure. The concentrations of Pb and Cr-Tot using calibration method were 0.058 mg/L and 0.018 mg/L, respectively. Meanwhile, the concentrations of Pb and Cr-Tot using the addition method were 1.1419 mg/L and 1.1036 mg/L, respectively. Based on this research, the addition method gives a relatively better value and fulfills the interval requirements in the AAS readings for low Pb metal concentrations.
