Abstract

Food is one of the basic necessities of humans. It is important to pay attention to the quality, safety, hygiene and sanitation of food. Healthy food should contain nutrients, vitamins, and the other essential substances for our body need. The food should be safe for consumption, and free from contamination. Food contamination generally occurs due to coliform bacteria contamination that can cause foodborne disease. This study aimed to analyze the total coliform bacteria and identify Escherichia coli bacteria in food and beverage samples in the canteen X. The design of this study was descriptive research. Samples were obtained from four sellers in canteen X. From each seller, one sample of mixed rice and one sample of iced tea were obtained. Samples were analyzed using the MPN (Most Probable Number) method to determine the total coliform bacteria and EMB (Eosin Methylene Blue Agar) media to identify E. coli. The results showed that all food and beverage samples were tested positive for coliform and E. coli with MPN values ​​exceeding the threshold value. The lowest contamination in the food sample was found in the MA1 and MA2 (460 MPN/gram) and the highest contamination was found in the MA3 and MA4 (>1100 MPN/gram), while the lowest contamination in the beverage sample was found in the MI4 (1100 colonies/100 mL), and the highest contamination was found in the MI1, MI2, and MI3 (>2400 colonies/100 mL).

Abstract

The increase in the amount of waste coupled with the lack of waste management facilities, as well as the lack of knowledge and public awareness in managing waste causes the accumulation of waste to have an impact on environmental pollution. In the Kesamben sub-district, Jombang, there is no waste management facility, so people choose to do open burning, throw garbage on the side of the road, and even throw garbage directly into the river. From these problems, a TPS 3R was planned in Kesamben District. In planning the TPS 3R, population data and population projections, waste generation data, waste composition, waste generation projections and local area HSPK are required. Data collection on waste generation and composition was carried out by sampling at residents' homes. The results of the sampling obtained the weight of waste generation of 0.1393 kg/person/day with a waste volume of 0.0022 m3/person/day. The composition of the waste consists of organic waste, plastic, paper, cloth/textile, glass, Styrofoam, and diapers. With the percentage of waste composition, respectively, namely 64.55%; 19.7%; 8.49%; 1.71%; 0.41%; 0.75%; and 4.38%. From this data, a TPS 3R building is planned which can process waste up to a volume of 164.55 m3/day. Consists of a reception room, sorting room, inorganic waste storage room, plastic waste processing unit, organic waste processing unit, liquid organic fertilizer storage room, residual waste storage room, and supporting facilities. From the planning that has been done, it takes a budget plan of Rp2.052.524.176,35.

Abstract

Organic waste bioconversion through maggot cultivation is believed to be a solution for managing organic waste based on a circular economy. Maggot cultivation has been widely carried out by Bank Sampah managed by the community in Indonesia, one of which is located in Bengle Village, Karawang District. Bank Sampah (BS) of Bengle Village has been able to reduce organic waste and produce Kasgot, reaching 75.00% and 25.00%, respectively. This study aims to examine nutritional content of maggot and characteristics of kasgot produced by BS of Bengle Village. The results showed that fresh and dried maggot contained quite high fat and protein, of 38.99%; 29.65% and 40.94%; 34.75%, respectively. These values make both maggots feasible as sources of animal fat and protein for poultry. Furthermore, Kasgot contains N-total, P2O5, K2O, Fe, and Pb each of 3.98%; 2.80%; 3.32%; 332.18 ppm; and 0.26 ppm has met the minimum specifications for solid organic fertilizer and compost from organic waste. However, the C/N ratio (6.40) and moisture content (22.77%) did not meet these standards and indicated that Kasgot was not stable as an organic fertilizer. Despite that, the quality of Kasgot can be improved through advanced fermentation processes such as vermicomposting so that it can be used as a substitute for inorganic fertilizers for plant growth and improve soil conditions.

Abstract

A research to model particulate emission was conducted in the plywood industry in Kendalrejo, Talun, Blitar Regency, East Java at an altitude of 273 masl. The industry already has an environmental pollution control unit, with an outlet through a chimney emitting an average emission of 0.14 g/s. The model simulation was carried out using AERMOD View software with data on wind direction and speed, solar radiation, temperature, clouds, and air pressure. The results show that the presence of the wood industry in Talun, Blitar Regency will have an impact on particulate emissions to areas in the east, southeast, west, and south, as the dominant wind direction. Dispersion modeling of particulate pollution with current conditions has resulted in dispersion with concentrations below the allowable limit in PP 22 of 2021. Modeling with several scenarios shows that the dispersion pattern can be maximized by increasing the chimney emission rate to 18 m/s, to minimize turbulence around the chimney and accelerate the reduction of particulate concentrations. Increasing the height of the chimney or increasing the diameter of the chimney will also affect the decrease in concentration in all directions so it becomes a recommendation that should be considered by the industry.

Abstract

Poultry farm is one of the important sectors in meeting human needs for animal protein, but it was not correlated with the availability of poultry meats due to their limited production. In order to provide an adequate source of animal protein, especially in Garut Regency, the initiator plans to develop the poultry farm located in Sirnagalih Village, Garut Regency. It is necessary to build environmentally friendly poultry farms that implement sustainable development. This study analyzes the environmental impact of poultry farm in accordance with sustainable development. This study aims to analyze the environmental impact of “Sirnagalih Poultry Farm” in Garut Regency as an Environmentally Friendly Poultry Farm. The research was conducted by using quantitative and qualitative descriptive analysis. Quantitative analysis was used to analyse land use, water concumption, poulty manure and poultry carcass. The qualitative descriptive analysis explains the environmental management. Based on land use analysis, the BSC (Basic Structural Coefficient) is 65.92% consisting of poultry buildings, feed warehouses and supporting facilities. The GBC (Green Basic Coefficient) is 16.42%. Wastewater from poulty farm can be treated by a wastewater treatment plant. Animal manure waste can be managed by composting, while poultry carcass management and green open space can refer to Government Regulations.

Abstract

Kopelma Darussalam is an education center in The Aceh Province which has the area of ​​206.2 hectares. There are 6 schools and 2 nerby public universities (Ar-Raniry State Islamic University and Syiah Kuala University) in the region. Transportation activities in Kopelma Darussalam remarkably can increase noise level primarily during studying and working hours. The purpose of this research is to determine the noise level and to map the noise distribution in Kopelma Darussalam. The mapping is created by using Surfer 13 software. This methode of this study is quantitative descriptive research. Primary data is obtained by using a Sound Level Meter (SLM) to measure noise levels on weekdays and holidays both outsides and indoors at 8 sampling locations. The data is then analyzed by using statistical equations provided by Decree of the State Minister of the Environment KEP-48/MENLH/11/1996. The results shows that the noise level at Kopelma Darussalam is in a noisy condition as it ultimately has exceeded the quality standard of 55 dBA, especially on weekdays at 2.00 to 5.00 p.m. The map of noise distribution at Kopelma Darussalam shows that the highest noise is coloured in red (≥ 67 dBA). This value has exceeded the quality standard which leads lecturers and students necessarily to speak louder in classrooms. Keywords: Noise, transportation, motor vehicle, mapping, Surfer 13.
