Abstract

The study aims to compare the effectiveness of chromium removal from water using adsorption by coal fly ash (CFA) and phytoremediation by vetiver grass (Vetiveria zizanioides L) as well as a combination of both CFA and vetiver grass. The experiment was carried out in four different reactors, having size of 100 cm (length) x 60 cm (wide) x 80 cm (height). One reactor was filled with gravel and CFA, without vetiver grass (RI), while another one was filled with gravel and vetiver grass, without CFA (RIV). The other two reactors were filled with gravel, CFA, and vetiver grass with the mass ratio of gravel/CFA of (25:2) and (25:1), denoted as RII and RIII, respectively. Fifty (50) L of synthetic wastewater containing 14.612 ppm of chromium was filled into the reactors and continuously recirculated for 15 days. Chromium accumulation in CFA and plants was analyzed on day 15. The results of plant development are indicated by the presence of new shoots and roots that grow during phytoremediation processes. In addition, there was an increase in weight and number of vetiver stems indicating the persistency of vetiver grass in such a harsh wastewater condition. The removal of Cr from wastewater in RI, RII, RIII and RIV at days 15 were 81%, 93.2%, 85.8% and 75.7%, respectively. It can be concluded that: (1) vetiver grass (Vetiveria zizanioides L) has high potential as phytoremediator plant, (2) Chromium adsorption by CFA plays important role in Cr removal from wastewater, and (3) combination of adsorption by CFA and a phytoremediation by vetiver grass significantly increases the removal of chromium from wastewater.

Abstract

Purpose: Markets are potential sources of increased waste production, especially after daily activities and settlements. Proper waste management in markets is essential to prevent environmental and public health issues. This study aims to evaluate the waste management practices at Pasar Induk (main market), Pamanukan, based on four management aspects: planning, organizing, actuating, and monitoring. Methods: This qualitative study used a case study approach. The number of informants in this study was 7, selected using the purposive sampling technique. The study was done in April-June 2021. Results: Pasar Induk Pamanukan lacks a work plan and SOP for waste management. Human resources and infrastructure facilities owned by Pasar Induk Pamanukan are insufficient for effective waste management. In addition, there is no official coordination between the TPS Pamanukan and the market manager. Enforcement of waste management at the Pasar Induk Pamanukan uses collection, transportation, and disposal techniques. There's no socialization for waste management to the traders. The market manager has abandoned the evaluation of waste management performance at Pasar Induk Pamanukan, and no improvement efforts have been made. Conclusion: The waste management at Pasar Induk Pamanukan, based on the management aspects of planning, organizing, actuating, and controlling, has not been fully implemented or well managed.

Abstract

Purpose: Food handlers still need to routinely wash their hands with hand soap or wear aprons/masks, as there are dirty outdoor areas and many flies in canteens at Kendari port. Previous studies found that education level, knowledge, attitude, training, and availability of facilities affect the implementation of food sanitation hygiene. However, there has yet to be research on the combination of these factors in influencing the implementation of food sanitation hygiene, and research on the application of food sanitation hygiene in port areas in Indonesia is still rare. The study aimed to identify one factor that must be present for the implementation of food sanitation hygiene that meets the requirements and does not meet the requirements and identify a combination of factors that influence the implementation of food sanitation hygiene. Methods: The study design was cross-sectional, and 16 canteens and 16 food handlers participated using total sampling techniques. Education level, knowledge, attitude, training, and availability of facilities were analyzed using Qualitative Comparative Analysis (QCA). Results: No single factor was mandatory for implementing food sanitation hygiene that meets or does not meet the requirements. QCA identified three pathways for implementing eligible and not-eligible food sanitation hygiene. Conclusion: Frequent or regular training and adequate facilities are essential to implement food sanitation hygiene that meets the requirements. Meanwhile, poor attitudes, never or rarely-received training, and inadequate facilities were essential factors that led to implementing food sanitation hygiene, which was needed to meet the requirements.

Abstract

Purpose: The 2018 healthcare waste management crisis catalyzed a critical review of the concerns expressed by the Health Office (dinkes) and healthcare facilities regarding healthcare waste management in the Special Region of Yogyakarta (DIY). Due to this crisis, the Ministry of Health hired Universitas Gadjah Mada (UGM) to look into potential solutions and promote DIY government policy responses. This paper examines the management strategy during crisis times and possible alternative solutions. Methods: This paper uses focused group discussions reports involving separate groups of (1) environmental health officials from community health centers, (2) hospitals, (3) environment health officials of district health authorities, and (4) cross-sectoral province officials in the Yogyakarta Special Region. It is part of a project 'A case study of strengthening regional-based medical waste management model', fund from the Environmental Health Directorate, Directorate General of Public Health, Ministry of Health (Project KN 01.03/6.1/0198/2019). Result: A simulation of policy options based on health facility managers suggests that a province-based system is the most profitable in the long term for DIY, with several possible options. The national policy roadmap was considered inadequate to respond to DIY's urgent local needs. Furthermore, the series of meetings succeeded in forming an informal forum between health facilities, provincial health offices, and associations of hospital environmental sanitation experts, monitoring medical waste management. Conclusion: The 2018 medical waste management crisis led to the formulation of policy response choices tailored to the capacity of DIY. These choices considered the expenditures and legal sanctions faced by healthcare facilities and the economic value of a region-based waste system for local government authorities. This comprehensive approach highlights the importance of local capacity. It needs to shape effective and sustainable medical waste management policies, underscoring the necessity of region-specific strategies in the face of national health crises.

Abstract

Purpose: Healthy and safe refillable drinking water must comply with Permenkes RI No 43 Tahun 2014 and Permenkes RI No 492/MENKES/Per/IV/2010. Increasing drinking water coverage in Lampung Province makes Kerawang water an alternative to meet drinking water needs because it is cheap, easy to access, and practical. This study aims to analyze the hygiene and sanitation of the Kerawang water depot. Methods: This qualitative study used a case study approach. Informants were recruited through the purposive sampling technique. The primary informants are 6, the touchers of the depots. One supporting informant was the Ambarawa Health Center’s environmental health officer. Results: Of the 17 depots observed, 3 (17.64%) water depots did not meet the requirements, and 14 (82.35%) met the criteria. Of the 17 depots that had been checked the quality, 17 (100%) depots were appropriate for the physical requirements, 11 (64,70%) depots were not suitable for the chemical requirements, 2 depots (11.76%) were not appropriate for the biological requirements. Conclusion: The infrastructures were cleaned at different times, and there was some lack of basic sanitation facilities. Equipment for the water treatment process was always replaced before the expiration. Some handlers did not check their health and apply hygiene behaviors. Depot owners must complete basic sanitation facilities such as handwashing stations, trash cans, and closed sewers, facilitate work clothes and health checks, control the hygiene behaviors of handlers, and conduct regular quality checks on drinking water.

Abstract

Purpose: Bad waste management causes the slaughterhouse's environment to look unsightly and unpleasant. This research aimed to evaluate the factors that cause odor pollution by X Slaughterhouse waste. Methods: This qualitative research used a case study approach. Informants were recruited through purposive sampling. The primary informants were six people who lived or worked around slaughterhouses. The supporting informants were the Head of the Slaughterhouse Division, the slaughterhouse's daily waste officer, and the Environmental Service's Head of Impact Assessment and Waste Management Division. Research conducted in Central Java. Open Code 4.02 was used to analyze the qualitative data. Results: Overall, the slaughterhouse's facilities were not appropriate for the requirements in SNI 01-6159-1999. The odor pollution caused by the waste discharged into the environment without proper management was supported by the results of the BOD level test from the slaughterhouse's sewers, 261,5 mg/L. The most significant discharge in the slaughterhouse's sewer was when the slaughterhouse had been cleaned, 0,137 m3/s, and the most minor discharge was during the slaughter activity, 0,006 m3/s. The slaughterhouse was disinfected after slaughter activity to protect the environment from slaughterhouse waste. Meanwhile, the Environmental Service has not made any specific efforts. Conclusion: Lack of adequate waste management facilities caused the odor pollution. It is necessary to stipulate waste management guidelines, supervise the slaughterhouse's waste management, and coordinate relevant services to monitor and evaluate it. The following researchers can observe using all the requirements in SNI 01-6159-1999.
