Domestic or industrial wastewater management and treatment in many developing countries tend to imitate the systems and technology from industrialized countries by adopting a centralized wastewater processing system and treatment technologies such as activated sludge or tertiary nutrients removal. However, the effort to replicate these methods, in fact, is not an appropriate solution to overcome the problems of sanitation in developing countries, particularly Indonesia. These sophisticated technologies require a large energy supply, skilled operators as well as substantial operating costs. Furthermore, these methods do not provide any opportunity to recover energy and valuable nutrients contained in wastewater. These reasons can cause wastewater management become unsustainable. This paper will present some alternatives and concepts in the management and treatment of wastewater. It will be limited to several natural wastewater treatment alternatives to support sustainable management of water resources in terms of both technology and financing. Some low-cost appropriate technologies for wastewater treatment will also be discussed include: anaerobic treatment, wastewater treatment by waste stabilization ponds.

Road Sadang – Gresik KM 51+000 to KM. 53+700 is in Panceng sub-district, Gresik district, East Java Province, which is a national road connecting Gresik district with Lamongan district, which is damaged due to being crossed by overloaded heavy vehicles or those that exceed the maximum load limit, increasing the load on the road surface by the wheels. vehicles can accelerate damage to the road structure (decreased road quality) which causes vehicle speed to decrease and results in longer travel times and can possibly endanger the safety of drivers (accidents). The aim of this research is to identify the types of road damage on the Sadang - Gresik Km. 51+000 to Km.53+700 and to determine the value of the road pavement condition using the Surface Distress Index (SDI). The results of this research are that in segments 11, 12, 14, 17, 18, 22 and 27, the damage that is sufficient to get a large SDI value is wheel ruts. Meanwhile, in segments 2, 3, 4, 5, 6, 8 and 15, the damage that received the largest SDI value with moderate damage classification was cracking. What dominates the road damage on the Sadang - Gresik road, Gresik from Km 51+000 to Km 53+700 or from segment 1 to segment 27 are ruts and cracks. In measuring the pavement surface of the Sadang - Gresik road, 2700 meters long which was divided into 27 segments, damage was obtained based on the parameters of the Surface Distress Index (SDI) method, namely crack area, crack width, holes and ruts. By obtaining Good SDI scores of 23 segments found in segments 1, 3, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, and medium SDI values of 4 segments found in segments 2, 4, 5, 6.

Perumda Giri Tirta Gresik Regency as the provider of clean water in Gresik Regency will develop a distribution pipe network in the Greenland Menganti Housing Complex in the next few years. Before development is carried out on the network, it is necessary to evaluate the existing condition of the distribution network system in the housing complex to analyze the problems that occur in the clean water distribution system. In evaluating the clean water distribution network system, researchers used EPANET 2.2 software. This research is a type of descriptive qualitative research. Observations were carried out by observing the condition of the existing water distribution pipe network, water pressure, water discharge and water flow speed in the Greenland Menganti Housing Complex. The results of running EPANET 2.2 software show that the lowest pressure value in the distribution network system is 12.04 mka and the highest pressure value is 19.59 mka. These results are still in accordance with Minister of Public Works Regulation Number 18/PRT/M/2007 for the minimum pressure criteria in distribution pipes is 5-10 mka at the furthest service reach point. The running results of the water flow velocity value in the pipe or velocity show the lowest value of 0.03 m/s, while the highest velocity value is 2.5 m/s. According to Minister of Public Works Regulation Number 18/PRT/M/2007, the permitted velocity value is 0.3 – 2.5 m/s, so these results are not in accordance with the planning criteria. An alternative to overcome this is to change the dimensions of the network pipes in several areas that are deemed less than optimal. In the process of evaluating this distribution network system only includes alternative solutions in general in accordance with existing literature without including comparison network images that have been processed in such a way as to obtain optimal data.

Ventilation as a building's air conditioning system has an important role in controlling temperature, air humidity, air quality and air movement. The function of ventilation, apart from producing clean air, also functions to remove polluting gases (contaminants). This research is entitled “Analysis of Air Ventilation Design on Comfort Feasibility in PT. AAA” which aims to provide comfort, improve industrial hygiene and reduce Acute Respiratory Infection diseases in employees which are caused by one of the chemicals in the form of Volatile Organic Compound (VOC). The method used in this research is a quantitative method with a descriptive approach. By using GVR calculations in accordance with SNI standards regarding procedures for designing ventilation systems (SNI 03-6572 (2001)). This research was carried out using an anemometer and an air quality detector to find wind speed, temperature and air quality values. The research results from a room area of 22 m² with a total of 5 employees and 1 exhaust fan and 1 AC had a room temperature of 30˚C and humidity of 54%, indicating that the room was less comfortable. The existing ventilation in a room measuring 22 m² shows that the air ventilation in the production room does not meet existing standards, which should have a total ventilation area of 10% of the floor area, namely 2.2 m². So in this case it requires additional natural ventilation in the form of casement windows with a size of 0.6x1.5, 2 pieces and also replace the exhaust fan with a size of 0.7x0.7 m, 1 piece.
