Abstract

The development of transportation is increasing rapidly from year to year in accordance with existing technological developments, currently transportation plays an important role in human life, roads are the means of transportation that play the most role in this, along with the increasing volume of passing vehicles as well as road widening of course. Produces a new problem that may still be underestimated, that problem is noise. One of them is a place of education or a school that is right next to the main road, namely Wiyata Mandala Junior High School, Bogor Regency. The speed of private vehicles has a significant effect on noise. From all analysis calculations, the biggest equation is found in the first day of the third point of research (Sound Level Meter 3), with a contribution of 28.95%. The calculation below shows, y = 61.62 + 0.004x1 at a distance of 15.25m SLM. This equation means that if there is no decrease in motorbike speed, the noise level on the SLM3 is 61.62 dBA. The second largest equation was obtained in the first day of research at the second point (Sound Level Meter 2) with a contribution of 27.14% based on the calculation of the equation below, y = 64.23 + 0.007x1 with a distance of 3.44m SLM. The purpose of the above equation is that if there is an increase in motorbike speed, private vehicle speed and public vehicle speed, then the noise on the SLM2 is 64.23 dBA. During the Covid-19 pandemic, motorcycles at moderate speed often passed this school area. So based on the results of observations and calculations, it was found that the decrease in motorcycles was 45% which crossed the Wiyata Mandala Junior High School Bogor.

Abstract

Banyuwangi Regency has a coastline of 175.8 kilometers, stretching from Meru Betiri National Park to Baluran National Park. Coastline changes occur due to human activities, abrasion and sedimentation due to climate change and global warming. Research to identify and predict changes in the coastline of Banyuwangi Regency due to climate change using GRASS QGIS in 2025. The results of predictions of shoreline changes in Banyuwangi Regency are located in Pang Pang Bay, Muncar District and Tegaldelimo District. In Banyuwangi Sub-district on Cacalan Beach, Cemara Beach and Marina Boom Beach, and on the southern coast of Banyuwangi in Purwoharjo District, namely Grajagan Beach, and in Pesanggaran District on Red Island Beach. Recommendations for mitigating shoreline changes with sandy and swampy beach types in addition to the application of ecotourism principles are also the implementation of wind barriers, mangrove rehabilitation, seawall construction, or TetraPOT. Vegetative and mechanical conservation efforts are a strong combination in natural and artificial defense from marine abrasion attacks.

Abstract

This study analyzes the effect of immersion of H2SO4 (sulfuric acid) solution with a concentration of 10% on porosity, density and compressive strength of mortar with PPC cement and geopolymer with white soil substitution mortar. The purpose of this study was to determine the resistance of mortar with PPC cement and geopolymer with white soil substitution mortar when immersed in 10% H2SO4 solution. The test object was 5x5x5 cm mortar with materials used including fly ash from PLTU Tanjung Jati B Jepara, white soil from Kupang, fine aggregate, water and alkaline activator in the form of a mixture of 8M NaOH and Na2SiO3 and also PPC cement. The composition of the geopolymer mortar mixture is 1binder: 3Fine Aggregate: 0,5Water-Binder Ratio, while the mortar with PPC cement is made with a composition of 1PPC: 3Fine Aggregate: 0,5Water-Cement Ratio. The geopolymer mortar was made in 6 variations with a white soil substitution percentage of 0-25% with an increase of 5% for each variation. Compressive strength testing using a compression test apparatus. The test results show that the variation in the percentage of white soil substitution has less effect on the size of the porosity value. As for the value of compressive strength and density, white soil substitution has an effect, the higher the white soil substitution, the higher the compressive strength and mortar density values. Geopolymer mortar was better to withstand 10% sulfuric acid solution, while mortar with PPC cement had no resistance to 10% sulfuric acid solution because it continued to deteriorate over the course of the day. The greatest compressive strength is in variation IV (15% white soil substitution) of 15,31 MPa at 28 days of age, while the smallest porosity and greatest density are in variation VI (25% white soil substitution) of 0,17% and 2,205 grams/cm3.

Abstract

As time goes by, the human population and mortality rates continue to increase. The population that is increasing is inversely proportional to the amount of land as a place of settlement, causing a serious problem. The same thing happens due to the increasing number of deaths every year, the lack of land that can be used as a burial place. This can be seen from the amount of land that has shifted from its function, so people often prefer practical methods such as cremation or corpses to reduce the impact of excessive land use.

Abstract

The wastewater treatment plant (WWTP) in the Nusa Dua area has implemented a stabilization pond to reduce organic matter and nutrients. Because it has been operating since 1980, it is necessary to evaluate the existing conditions. The aim of this study was to determine the percentage of organic and nutrient reduction from the WWTP system. Organic removal in the form of BOD and COD parameters were 71.84% and 75.11%, respectively. Meanwhile, nutrient parameters in the form of NH3-N, TN, and TP have a percentage of 83.64%; 59.41%, and -375.81%, respectively. TP is the only parameter that has increased, causing a problem which is caused by the explosion of algae population in the reservoir. TP allowance should be a concern in choosing advanced treatment.

Abstract

The increasing number of residents every year causes the need for transportation to also increase, this also occurs on the Sukabumi-Bogor Primary Arterial Road which is a road with a fairly high volume of traffic flow, in addition because the industrial center and tourism sector are located right on the national road, Insufficient geometric roads caused by the increasing number of vehicles is also a factor that affects the high number of traffic accidents along the Cibadak – Bogor Road. The purpose of this study was to analyze the characteristics of the accident-prone areas (blackspots) on the Jl. Surya Kencana, Pamuruyan Village, Cibadak District - Jl. Raya Ciutara, Pondok Kaso Landeuh Village, Parungkuda District. The method used in this study is the EAN (Equivalent Accident Number) method and the Cussum (Cumulative Summery) method. From the results of the weighting using the EAN method, it was identified that STA 1, STA 4, STA 5, and STA 6 were blackspots. Meanwhile, the Cussum method identified STA 1, STA 4, STA 5, STA 6, and STA 9 as blackspots. The right type of handling for accident-prone locations from the observations, among others, is making a thunder strip facility close to the zebra cross area to reduce vehicle speed and installing a safety fence on the shoulder of the road so as to minimize road crossings that directly cross the road without using zebra cross facilities.

Abstract

Sultan Hasanuddin International Airport as one of the supporting sub-sectors of air transportation should be able to prepare and take strategic steps to proactively provide services and support customer needs for both airlines and passengers. This type of research is descriptive qualitative. The method of collecting data and information is Participatory Rapid Appraisal (PRA). Data analysis with statistical methods. The results showed that the physical facilities, the level of reliability of the officers, the responsiveness of the officers, the security guarantees, the attitude of the officers' empathy, the work environment at Sultan Hasanuddin Airport, showed a fairly small number of significance and had no effect on the level of passenger satisfaction. This can be interpreted that passenger satisfaction is quite good, but in this case to achieve a better value of passenger satisfaction, it is necessary to follow up so that the six variables get better attention so that the coefficient number is close to zero. It is recommended to improve both aspects of physical facilities and performance. The role of officers in serving passengers at Sultan Hasanuddin Airport Makassar.

Abstract

Cement and lime are widely used as stabilizing agents for soft clays. Some pozzolanic materials have also been used as additives such as asphalt, geosta, fly ash (geopolymer), base ash, salt. Industrial waste such as rice husk ash, coal burning ash (geopolymer) is also used as an alternative for stabilization materials. This research aims to study the effect of sawdust ash, as wood waste, to replace cement and lime on the stabilization of high plasticity clay. The effectiveness of sawdust ash, in this study, was evaluated from the CBR value. The test samples were also reviewed under conditions with and without immersion and with and without curing. Based on the test results, lime is very effective as an additive because it increases the CBR value of more than 100 at a level of 10%. Wood husk ash also increases the CBR value by 100%. The use of cement, lime and wood husk ash requires curing time so that there is a strong bond between the clay and additives. The use of additives without curing did not increase the CBR value. In the stabilization of clay with 10% lime, replacement of lime with wood husk ash by 4%-6%, can be used as a road sub-grade with good quality.
