Abstract

Maluku Province is an area with minimal access to sanitation because of its archipelagic location. Access to sanitation is one indicator of sustainable development goals (SDGs) that must archive in 2030. To achieve sustainable universal sanitation access, an indicator is needed that can be used to make policies that can grow access to proper sanitation. This study aims to determine the factors that can improve sanitation in Maluku Province. The development of livable housing must also pay attention to access and proper sanitation. This study used secondary data to analyze multilinear regression of socioeconomic impact on access to sanitation. Economic growth affects people's welfare. Economic growth is usually followed by a reduction in poverty, an increase in the Human Development Index (HDI), and an expansion of employment opportunities. This study uses secondary data from 2006 to 2016. Integrating human development, reducing poverty, and increasing residential ownership is needed to increase Maluku Province's sanitation access. With improved policies and better master plans for improving the quality of social variables, this variable will also affect increasing access to sanitation in Maluku Province. Better policy and programs from the central and local governments should seek to reduce poverty levels to improve access to sanitation in Maluku Province.

Abstract

In HRC production at PT XYZ which is carried out continuously to pursue the production target will be in effect on the HRC production component with the risk management methods is Failure Mode, Effect and Criticality Analysis (FMECA). The purpose of this study is to identify the source of potential failure in HRC production, analyze the RPN value, and determine control recommendations. Data collection methods are carried out by means of direct observation of HRC production, interviews, and literature studies. The results on the risk assessment by the FMECA method are leakage and operational failure of the burner device with a RPN value of 420, the Refractory Brick Furnace crack of 324, the scale piece bounced off the 294 reservoir, the oil leak on the flat pass, the work roll, and the backup roll of 252 , damage to the roller table machine is 240, operational failure on the Looper engine of 240, and the failure of the HRC product binding manually is 240. Risk control in HRC production is the use of flame rod indicators, ultraviolet sensors, ultrasonic tests, installation of slab pieces cover, thermal infrared camera, LOTO use, quadratic linear inverse system or predictive control, distance guard, and periodic maintenance.
COCONUT LEAF WASTE PROCESSING WITH BIODRYING PROCESS AS RAW MATERIAL FOR BIOMASS PELLETS IN WASTE TO ENERGY Ulhasanah, Nova; Sarwono, Ariyanti; Yosafaat, Michael; Filippi, Dennis; Sari, Mega Mutiara; Suryawan, I Wayan Koko

Abstract

Coconut leaf waste is a type of waste that contains a good enough calorific value to be used as raw material for biomass pellets. The minimum standard calorific value of biomass in Indonesia according to SNI 8675:2018 is 16.05 MJ/kg. Meanwhile, based on the research results, the calorific value of coconut leaf waste has a value of 13.34 MJ/kg. The way that can be applied to increase the calorific value is by biodrying. This study aimed to determine the effectiveness of the biodrying process in processing coconut leaf waste. This study use bioactivators in the form of tempe yeast, baker's yeast, and tapai yeast. Mass loss and moisture reduction can be achieved, respectively, 8.25-17.62% and 62.4-65.6%. The calorific value can reach the minimum standard after seven days of processing with a value of 17,995-18,623 MJ/kg.

Abstract

Water is a human need to carry out activities ranging from daily essentials to agricultural needs and others. Domestic wastewater must meet physical, chemical, and biological requirements so that humans cannot be polluted by the water, especially the water around the Pasir Panjang Village area in Batam, Riau Islands. This study aims to determine the potential use of water hyacinth for environmental health. This research was conducted by direct observation and measurement of water quality by grab sampling. Observation results show that not all residents use septic tanks as wastewater treatment results from daily activities. Some residents drain their wastewater directly into water bodies or surrounding land, resulting in decreased environmental aesthetics. Water quality testing for nutrient parameters shows that the quality standards have been met. However, further measurements are needed for total nitrogen and phosphate. Besides that, it also causes a population explosion of water hyacinth. In addition to the ability to treat water hyacinth waste, its economic potential is also analyzed. The growth of water hyacinth is sufficient and fulfills its capacity, and water hyacinth can be used for various crafts that can improve the community's welfare.

Abstract

PT. X is a pharmaceutical company that produces wastewater with the potential to harm the environment. Although the company already has a wastewater treatment system in place, this study evaluates its performance through direct field surveys and qualitative analysis based on ideal treatment standards. The treatment system at PT. X uses a series of five stabilization tanks operated in a continuous flow. However, BOD and COD test results from November 2019 to March 2020 show that the treated effluent does not meet the required pharmaceutical wastewater quality standards. This indicates the need to redesign the existing treatment system. One solution is to improve the biological treatment process, as the current BOD/COD ratio of around 0.5 suggests poor biodegradability. In addition, introducing an electrocoagulation process could enhance performance, with COD removal efficiency reaching up to 55.4%.
