Following the plan, we conducted this research as a baseline hydrogeological study within an area of ​​​25 km2. We find a set of Late Oligocene – Quaternary rocks showing deep sea to terrestrial deposits of Limestone, Sandstone, and Lahar. Several small folds and faults are also found in the area. All rocks serve as the aquifer in the area. The groundwater flows from south-southeast to northwest-west. We measured the physical parameters (temperature, TDS, EC, and pH) of more than 25 springs and dug wells, and 5 samples for major element tests in the laboratory. Referring to hydrochemistry using multivariable statistics, we classify the samples into two types: 1) shallow groundwater type is an immature groundwater with a close-range recharge area, short residence time, and low TDS/EC values, 2) shallow groundwater with a long-range recharge area, longer residence time, with a slightly higher TDS/EC values. We believe secondary permeability controls the flow of type two. However, the water should be drinkable after boiling.

Ganesha No. 10, Bandung, Indonesia c) Atmospheric Science Research Group, Faculty of Earth Sciences and Technology, Bandung Institute of Technology, Jl. Ganesha No. 10, Bandung, Indonesia Abstract Water contamination and flooding are two main problems that occur in the Upper Citarum River. The analysis of the 3D distribution of hydraulic conductivity in the unconfined aquifer is important to understand the interaction between groundwater and Citarum River, which may relate to the water contamination and flooding. We used the field data of the hydraulic conductivity parameter from thirteen large-diameter dug wells using the slug test method, and groundwater and Citarum River physical parameter, i.e. total dissolved solids, pH, and temperature. The hydraulic conductivity of the unconfined aquifer in the Upper Citarum River ranges from 8.34 x 10-7 to 2.19 x 10-5 m/s. The results indicate that areas with relatively high hydraulic conductivity, i.e. Ciparay and Solokan Jeruk Sub-districts, will have a greater possibility of groundwater or river water contamination depending on their interaction. Meanwhile, the area with almost flat topography and relatively low hydraulic conductivity, i.e. Majalaya and Baleendah Sub-districts, will be more susceptible to flood. Therefore, the solution or mitigation of the problems should consider the 3D hydraulic conductivity distribution, e.g. by installing some automatic water quality recorder in some dug wells with high hydraulic conductivity and installing recharge well to eliminate the artificial runoff.

Utilization of Solar Power for Support Facilities in the Evacuation Area during Natural Disaster ASM Atamtajani, Juan Ramadhan, Hardy Adiluhung, Diena Yudiarti INDUSTRIAL DESIGN - TELKOM UNIVERSITY Abstract A natural disaster is a disaster that is very detrimental to living things around it. Surely the disaster has a natural trigger source, for example in the case of a potential earthquake in the city of Bandung caused by a lembang fault in the area of West Bandung. Electricity is often a problem in areas where refugees fled after natural disasters. The problem of wasteful diesel generator energy resulted in the absence of an effective source of electricity and lighting, other than that information or the distribution of the area is still fairly slow due to the portable speaker system and even door-to-door announcements. From these problems, an emergency lighting and emergency wireless loudspeaker product can be designed to be provided in each of the evacuation tents. By using the X-Problem method consisting of immersion, convergence, divergence, and product adaptation are designed with a focus on an effective and efficient function approach.

Availability of suitable cultivation areas in Indonesia is limited whist demand for the crop is increased. This research evaluated growth and yield of carrot in warmer temperature of lower land elevations, and examined capability of biofertilizer to increase growth responses and yield of the crop under sub-optimal temperature conditions. The biofertilizer application may offer suitable green technology for production of carrot in lower latitudes, Three experiemnts were conducted in three different land latitudes. The first and second experiments were conducted in medium latitudes of 650 m above sea level (asl) and 550 m asl, while the third experiment was conducted in low land of 170 m asl. The experiments compared growth and yild of carrot plants with biofertilizer and without biofertilizer applications. The growth and (asl), growth and yield of carrot were enhanced by biofertilizer application when planted in ca. 650 and 550 m asl. The biofertilizer treated plants were taller, had a higher number of leaves, higher yield, carrot diameter and sweater than non treated plants. In low land, however, biofertilizer ad no effect to plant growth and yield although they were sweeter than untreated plants.

Agricultural air pollution in Indonesia: A mini-review Aulia Fauziah Luayi (a*) Puji Lestari (a) (a) Major of Environmental Engineering, Bandung Institute of Technology Jalan Ganesha No.10, Bandung 40123, Indonesia *auliafluayi[at]gmail.com Abstract Indonesia is an agricultural country that is a majority of the population consuming rice, corn and sugar cane for daily energy. But farmers tend to do open burning to their agricultural waste. The open burning practice of agricultural waste is filled with PM2.5 which contributes to air pollution. The research of air pollution modelling in Indonesia often uses the default value of global inventory. This gives the modeling results that are less representative of the situation in Indonesia. Therefore, it is necessary to develop a PM2.5 emission inventory from the agriculture sector in Indonesia. In addition, the inventory of PM2.5 emissions from the agricultural sector in Indonesia is still relatively minimal. In addition, Hafidawatis research (2019) still focuses on agricultural burning activities and has not been able to identify the PM2.5 emissions from the preparation of agricultural land activities. In fact, according to Li et al., (2019) The two largest emissions of PM2.5 on the agricultural sector came from agricultural biomass burning activities and the preparation of agricultural land. Therefore, a comprehensive inventory study need to be investigated immediately in order to determine local factor emission as a better representatives input for agricultural air pollution modelling in Indonesia.

RESPONSE OF WHEAT (Triticum aestivum) GROWTH AND YIELD TO DIFFERENT WATER SHORTAGE PERIODS Akhmad Zubaidi, Wayan Wangiyana, Herman Suheri, I Komang Damar Jaya, Dwi Ratna Anugrahwati, Nihla Farida, Sriwangi Pascasarjana, the University of Mataram Abstract Wheat plants can grow and produce well on the island of Lombok ranging from highlands to lowlands around 400 meters above sea level and have opportunities for further improvement. This adaptation effort needs to be followed up with development of cultivation technology, including proper irrigation. Irrigation is a fundamental factor in achieving maximum yields in a crop. Wheat is a crop that does not require a large amount of irrigation as much as rice plants, but it is not yet known which growth periods are critical to water shortage for wheat plants. This study aims to determine the effect of water stress on different growth phases of wheat on the growth and yield of wheat plants. This research was conducted using the Experimental Method in a greenhouse, with 8 water stress treatments at different phases From the results of this study it can be seen that the critical periods of water requirements for wheat plants occur when the plants reach the generative phase; yield is decreased significantly, especially when water stress occurs in the phases of heading and flowering (anthesis). Stress in booting and ripening phases also shows reduction on seed production, even at the lower level. The treatment of water stress in all development phases does not have a different effect on plant growth.

Various Techniques on Activating Carbon (Charcoal) for Cosmetic Materials As an Effort of Local Plant Empowerment Dwi Atmanto Engineering Faculty - Jakarta State University Abstract The purpose of this research activity is to identify the technology of making cosmetic products that are produced from charcoal whose raw materials are from local plants such as bamboo or coconut shells. The activated charcoal produced is mashed until homogeneous. The method used in this activity is the socialization and demonstration of cosmetic technology with the raw material of activated palm shell charcoal and skin moisture testing with a skin analyzer. Activated carbon or charcoal is material in the form of granules or powder derived from carbon-containing materials such as coal, coconut shells, and so on. With a particular treatment that is the activation process such as treatment with high pressure and temperature, activated carbon can be obtained which has a large inner surface. Charcoal is a porous solid containing 85-95% carbon, produced from materials containing carbon by heating at high temperatures. When heating takes place, efforts are made to avoid air leakage in the heating chamber so that the material containing carbon is only carbonized and not oxidized. Besides being used as fuel, it can also be used as an adsorbent. Absorption is determined by the surface area of the particles and this ability can be higher if the charcoal is activated with chemicals or by heating at high temperatures. Thus, the charcoal will experience changes in physical and chemical properties. Such charcoal is referred to as activated charcoal. The active ingredient in charcoal can be used to make cosmetic products among anti-dandruff creams, anti-acne masks, and other cleaning products.

Community Adaptation Model As Climate Change Mitigation Efforts Dwi Atmanto Engineering Faculty - Jakarta State University Abstract Climate change is a fact that must be faced by people on earth. In addition, climate change is not only a consumption of academics, governments and business people simply because this topic has become a public discussion because its effects are felt directly and real. The mass media, both print, electronic and online also enlivened the topic of climate change by disseminating research findings related to climate change, including reporting on challenges, opportunities and community practices in efforts to prevent and adapt to climate change. Considering that the impacts are more extensive and significant, comprehensive, integrative and holistic handling is needed. data obtained through surveys. There are two main concepts introduced to deal with the effects of climate change, namely mitigation and adaptation. Mitigation and adaptation to climate change is an important effort to deal with the impacts of climate change. In short, mitigation means an effort made to prevent, contain and / or slow down the effects of greenhouse gases that cause global warming on earth. Contrary to mitigation, adaptation is more to the efforts made to adjust (community adaptation) to the impacts of climate change that have occurred and are felt by humans on earth. Mitigation alone is not enough, and just adaptation. Both of them have to go along. Therefore, both mitigation and adaptation are very important to be done together and integrated in dealing with climate change.

Various Sources of River Pollution and Its Control Models Dwi Atmanto Engineering Faculty - Jakarta State University Abstract The disposal of wastewater, whether sourced from domestic (household) or industrial activities, can cause environmental pollution if the waste water quality does not meet the waste quality standard. For example, the population density of Jakarta city causes the distance between houses to be closer together, especially in congested areas, so that the location of septic tanks, cubluk (garbage box), and garbage disposal are close to groundwater sources. Some groundwater sources have been contaminated by coli bacteria, from 636 groundwater samples tested there were 285 samples containing E. coli bacteria. Whereas chemically, 75% of these sources do not meet the standard water quality standards for drinking water. Parameters that exceed the quality standard are nitrate, nitrite, iron, and manganese. The presence of nitrates and nitrites indicates that groundwater has been polluted by organic substances. In terms of river water quality, based on the results of monitoring it is seen that in general the quality is not in accordance with its designation and tends to deteriorate from year to year. Observing environmental conditions that tend to deteriorate, then wastewater management must be carried out properly and thoroughly in addition to increasing supervision of waste disposal from sources of pollution, among others through the clean-up program (Prokasih), water-saving movements, application of waste water discharge permits, increasing drinking water services, and improved sanitation, especially in dense residential areas Keywords: river pollution, controlling models, various resource pollutant Share Link | Plain Format | Corresponding Author (Dwi Atmanto)
