Water from dug wells is one of the sources of clean water used by the community both in villages and cities. Groundwater consumed by the community must have quality in accordance with the specified requirements. One of the important parameters is the presence of Escherichia coli bacteria (E.coli). The aims of this study is to identify the presence of Escherichia coli bacteria in dug well. In addition, to determine the correlation between the distance of the pollutant source (cowshed and septic tank) and the well. The analytical method used is univariate descriptive method and quantitative analysis. The results showed from 7 wells that were used as research objects, there were 4 wells positive for E. Coli bacteria and 3 wells were negative for E. Coli bacteria. The correlation value test showed that the pollutant source from cowshed had a coefficient of determination of R 2 = 0.911 or 91.1% which means that there is a strong relationship between the presence of E.Coli bacteria in the well and cow dung. As for the pollutant source from the septic tank, the results of the correlation test show the value of R 2 = 0.201 or 20.1% which means that the relationship between the presence of E. Coli bacteria and the septic tank is not strong. Septic tanks construction that conform to standards are one of the factors that cause dug well water quality to remain protected from pollutants.

The role of water in daily life, including activities in the mosque is very significant. The existence of the Ulul Albaab Mosque which is always busy with various congregation activities and activities carried out by students and the campus community affects the need for clean water. So far, the ablution used water at the Ulul Albaab Mosque has been dumped into the sewers. Measuring the quantity of water to determine the volume of ablution used water at the time of obligatory prayer is the first step to assessing its potential utilization. The number of congregation who perform ablution is directly proportional to the number of congregation of the Ulul Albaab Mosque. The average congregation of the mosque is 857 people/day and the average number who perform ablution is 778 people/day. The results showed that the volume of water used for ablution was 3.9 liters/person with an average time required for ablution of around 64 seconds. The use of recycling ablution water can be used for non-consumption needs.

The mobility of using LNG is based on its advantages as a substituent fuel for gasoline and diesel, where LNG has low emission properties. The process of mobilizing the distribution of LNG has the potential for accidents when it takes place. The study was conducted to determine the hazards that can occur and the safe distance for evacuation in the event of a leak using ALOHA simulation. The research process is carried out by studying literature, collecting data, determining the month and time of release, and continuing with a simulation of the existing data. The data analysis technique was carried out by determining the tank temperature and water dispersion model at 31 SPBG. Fireball simulation results at 8:00 a.m. 2:00 p.m, and 10:00 p.m have safe distances at 812 meters, 812 meters, and 815 meters. Fire column simulation results at 8:00 a.m. 2:00 p.m, and 10:00 p.m have safe distances at 29 meters, 29 meters, and 28 meters. Vapor cloud simulation results at 8:00 a.m. 2:00 p.m, and 10:00 p.m have Lower Explosive Limits (LEL) at 169 meters, 160 meters, and 243 meters. Thus the ALOHA simulation can represent the safe distance of evacuation and scenarios in the event of an accident.

The environment is one of the important factors in the success of an industrial company. This triggers the company to improve overall performance to implement a better environmental management system. ISO 14001 is an international standard that can be applied by companies to maintain and improve environmental management systems. This study aims to analyze the application of environmental management systems at PT. XYZ and know how far the company is ready to implement ISO 14001. The method used in this study is the Self Assessment Checklist for assessing clauses at ISO 14001. Data collection is done by observing the study site and conducting interviews with employees to obtain information at the company. Data processing is done by assessing the ISO 14001 clause with a self assessment checklist. The results of this study note that the value of the company's readiness to implement an environmental management system based on ISO 14001 standards is equal to 50.41% with a weak category.

Pantai Sawarna di Kabupaten Lebak memiliki keindahan alam yang dapat digunakan sebagai daya tarik objek wisata bagi setiap pengunjung. Keindahan alam pada kenyataannya tidak terhitung menjadi nilai ekonomi atau tidak memiliki nilai pasar, sehingga pentingnya dilakukan valuasi ekonomi untuk memperkecil eksternalitas yang dapat menyebabkan kegagalan pasar karena suatu barang atau jasa yang tidak memiliki nilai pasar, sehingga dalam kajian ini bertujuan untuk menentukan nilai ekonomi Pantai Sawarna dari sumberdaya alam yang tidak memiliki nilai Pasar. Metode valuasi ekonomi yang digunakan adalah metode biaya perjalanan dengan pendekatan individu (Individual Travel Cost Method). ITCM dipilih sebagai pendekatan yang lebih teliti dalam menilai kondisi sosial ekonomi pengunjung sehingga mengetahui nilai ekonomi dan nilai Willingness To Pay dari biaya perjalanan pengunjung. Willingness To Pay (WTP) dijadikan untuk mencari nilai ekonomi dan surplus konsumen area Pantai Sawarna. Hasil dari valuasi ekonomi dengan pendekatan ITCM yang digunakan di area Pantai Sawarna tersebut didapat nilai rata-rata WTP sebesar Rp. 93.672,-/pengunjung, dan nilai ekonomi Pantai Sawarna adalah Rp. 6.722.558.424,- / tahun.
