The HPGe detector is a device that should be cooled when used and can be operated at room temperature. For this reason, it is necessary to monitor the temperature and humidity in the HPGe detector storage area to produce optimal performance. This research was focused on designing a Smart Detector Environment System as a means of monitoring and automatic control of temperature and humidity in the HPGe detector storage. Temperature and humidity detection in the system was carried out by the DHT22 sensor connected to Arduino Uno and the motor driver module. Arduino uno gave the command "00000011" to detect the temperature in the chamber, and "00000101" to start the detection of humidity in the chamber, then the data generated by the DHT22 sensor would be displayed and processed by LabVIEW, which was used to move the fan to regulate the temperature and humidity in the system with the condition that the lamp on the chamber was left on (manual). The results obtained were in the form of a design and automatic control of temperature and humidity monitoring and control in the HPGe detector storage whose temperature could be adjusted automatically according to the needs of the HPGe detector.

Leachate is one of the results of rainwater infiltration and the degradation of microorganisms in waste. Some leachate types usually contain salinity which is an inhibitor in biological treatment processes. Aerobic biological treatment usually also requires sufficient dissolved oxygen (DO) levels. This study aimed to determine the effect of salinity on oxygen transfer in saline leachate. This study used a DO meter to measure the DO concentration in the 2 L volume reactor. There were two variations, namely leachate without salinity and with salinity 6 ppt, where the processing was carried out with three repetitions. The final oxygen transfer coefficients for the leachate without salinity and with salinity were 0.021 and 0.014, respectively. While the detention time required for leachate without salinity is 47.5 minutes, it takes 71.43 minutes with salinity.

Jatigede dam development in Sumedang, West Java, was planned in the 1960s and facing a dynamic revolution in Indonesia’s Governmental System. The political shift causes a change in the government’s priority of development, and as a result, this project had been postponed for decades. In the 1980s, The Government had given land compensation to the rural householder who lives at the site plan. The long-postponed development execution makes rural people unaware to leave the site and continue living on the compensated land for generations. Then in 2012, Government decides to execute the development as a targeted Indonesian Economic Master Plan to boost economic growth. This sudden regulation causes shock and stress for rural people’s livelihood since they should change their way of living in a short time since access to resources became limited by inundation. However, the Dam development unavoidably causes rural transformation that has an impact on rural people’s livelihood. Rural Livelihood transformation can be seen in livelihood assets including natural, financial, physical, human, and social assets condition after the inundation. This paper aims to identify the condition of rural livelihood assets as an impact of rural transformation caused by Jatigede Dam development in Sumedang, West Java. Therefore, the study outcomes were determined as a recommendation for preventing vulnerability by implementing programs for the impacted rural household.

Indonesia has two seasons, namely the dry season and the rainy season where the rainfall in the two seasons has a very large difference. Rainfall in the rainy season will be a source of groundwater reserves, because in the dry season there tends to be no rain. Efforts to increase groundwater reserves are carried out, among others, to use environmentally friendly drainage, namely by using infiltration wells and water will be infiltrated so as to reduce runoff.This research will begin by mapping the land covered by buildings in Kalongan and then calculating the area of land covered by the buildings. Rainfall data used is data at the Maguwoharjo rain station which is close to Kalongan with a span of 10 years. The number of infiltration wells currently available is 8 and by analyzing the needs of infiltration wells it will be known how many infiltration wells are needed so that as much water can be infiltrated to reduce runoff and increase groundwater reserves.The results of the frequency analysis for rainfall with a maximum return period of 5 years as a basis for planning infiltration wells. This large runoff during the rainy season can be reduced by having sufficient infiltration wells, so that rainwater entering the infiltration well will become a source of groundwater reserves. The total requirement for infiltration wells is 464 pieces with a diameter of 80 cm and a depth of 3 m. There are 8 infiltration wells so it is necessary to make 456 infiltration wells to reduce runoff.Keyword: groundwater, infiltration, runoff

Introducing alternatives material on cement-based material manufacturing is the need for environmental sustainability due to the excessive mining of sand from quarry and river bed. At the same time, industrialization headed to an uncontrollable growth of waste. This fact encourages the researcher to enhance the utilization of recycled waste in construction practice. On one side, it affords a solution for waste management, and on the other hand, it contributes to an eco-friendly construction material that minimizes the environmental impact. This paper aims to investigate the usability of the iron waste obtained from the wrought iron industry, as natural fine aggregates replacement. In particular, it focused on studying the physical characteristic of waste aggregates and the effect of partial replacement of natural sand on mortar strength. Mortar cube specimen made with various levels of replacement (0%, 10%, 20% and 30 %) and also various cement-aggregates volumetric proportion, which are 1:3, 1:4, 1:5, 1:6, and 1:7. All of the measurement parameters are taken consecutively based on ASTM norms. The current work remarks that both waste aggregates and natural aggregates reveal complete fulfillment in the aggregate requirement of ASTM standard. Furthermore, the mortar cube test confirmed that the mortar passes the strength grade for N class and O class, which suitable for the above-grade and non-load bearing application.

Corrosion is one of the processes of metal damage or degradation due to redox reactions between a metal and various substances in its environment that produce undesirable compounds. In the water one of the environmental parameters is water resistivity. By knowing the connection between water resistivity and corrosion rate, it is possible to monitor laboratory tests with water environments that have different levels of corrosiveness. Therefore, it is necessary to conduct an analysis to determine the effect of water resistivity on water corrosivity, understand the factors that influence the corrosion rate and calculate the corrosion rate of the irrigation gate steel plate on the water environment. This analysis uses a laboratory scale, analysis with talagasari irrigation water media, domestic wastewater, PDAM water and dead river estuary water. All water media used have a high level of corrosiveness. The factor that causes the low resistivity value is the large amount of inorganic minerals containing metal in the water so that at low resistivity values the corrosion rate increases. In the results of this laboratory analysis, it is proven that the more acidic the water medium, the faster the corrosion rate and the more alkaline the water medium, the slower the corrosion rate.

ABSTRACT: Until now, monitoring the landfill volume in the Sarimukti landfills is calculated by the ratio of trucks converted from tonnage to volume based on the density of the landfill. The various truck specifications and the landfill density conversion process affect the tonnage value. This has an impact on the accuracy of the landfill volume calculation results. This research uses drones as the main tool for monitoring Sarimukti landfills by making a 3D map of the landfill in 2021 as a reference for calculating the volume of existing landfill. The analysis was carried out by comparing the existing landfill volume with the projected landfill volume in 2025 according to the operational period of the landfills. The results of the analysis show that the Sarimukti landfills can no longer accommodate landfill by 2023.Keywords: Drone, Landfill, Contour

Reducing the cement content in concrete is the need for environmental sustainability, as cement produces a significant carbon emission. This work aims to study the effect of partial replacement of the cement utilizing fly ash at the various percentage of substitution by investigating the physical characteristic of concrete ingredients, compressive testing at various curing age, workability, and material cost reduction. Fly ash used in this research is categorized as type F, which obtained from Jepara powerplant. Along with fly ash, ordinary pozzolan cement (OPC) from Semen Gresik used as binder material. The fine and coarse aggregates quarried consecutively from Magelang Regency and Kulon Progo Regency, Indonesia. All the constitutes being observed on specific gravity, gradation test, clay lumps content, and abrasion resistance. The job mix formula developed adopting Indonesian Standard based on the physical data obtained previously, resulting in five levels of cement replacement which is 0%, 15%,20%, 25%, and 30% compared to cementitious weight. Concrete cylinder specimen having 150 mm on the diameter and length of 300 mm, tested at various age (7,14, and 28 days) to obtained compressive strength and strength development during curing age. The current works remarks that all level of replacement obtained a good agreement with targeted compressive strength (25 MPa) at the age of 14 days. However, the more fly ash supplemented in the mixture, strength development possesses a slower rate and a slight declining on workability. Eventhough the slump value still comply with the requirement given by the Indonesian Standard.

The massive use of natural materials in major road infrastructure frequently disrupts the sustainability of the ecosystem in the environment. A solution for using other materials is needed to minimize the impact of using these natural materials. GBFS (Granulated Blast Furnace Slag) is waste from blast furnace combustion of iron and steel material in granular form, which characteristically can be used as a substitute for medium aggregate asphalt mixture material. The study was conducted by several testing, such as GBFS material testing, AC-WC asphalt mixture characteristic test using Absolute Density Method, and performance testing on AC-WC asphalt mixtures, based on its structural performance and dunctional performance with the percentage of GBFS as medium aggregate variation at 0%, 50%, 75%, and 100%. The study results show that the utilization of the percentage of GBFS as a medium aggregate substitution by 75% improves functional performance and structural performance of AC-WC asphalt mixture.Keyword: GBFS, Asphalt Mixture, AC-WC, Medium Aggregate.
