Abstract

Big data seperti data twitter sudah cukup banyak digunakan dalam kajian ilmu sosial, tetapi penggunaannya dalam kajian bencana masih jarang di Indonesia. Sehingga tujuan dari penelitian ini adalah mencari tahu informasi apa saja yang dapat diidentifikasi melalui data media sosial twitter. Data yang digunakan dalam penelitian ini adalah data kualitatif dari angket dan data twitter dari sistem big data bernama Drone Emprit Academic (DEA). Data twitter yang bergeotag juga divisualisasikan dalam bentuk peta untuk membantu proses analisis deskripsi yang merupakan analisis utama dalam penelitian ini. Hasil dari penelitian ini menunjukan bahwa di twitter bencana banjir lebih mendapat perhatian ketimbang bencana longsor. Pada penyelenggaraan penanggulan bencana, kami berpendapat bahwa data twitter dapat digunakan pada semua fase. Data twitter dalam penanggulangan bencana terutama bencana hidrometereologis memiliki kelemahan seperti hanya bisa digunakan pada kota besar di Pulau Jawa. Kelemahan lainnya adalah informasi dari data twitter belum dipastikan apakah mewakili karakteristik demografi yang sama dengan kondisi dilapangan serta tingkat kevalidan informasi yang belum bisa dipertanggungjawabkan.Kata kunci— Twitter, Media sosial, Bencana, Banjir, Longsor

Abstract

During the COVID-19 pandemic, the use of masks is an obligation for everyone to maintain the transmission of the virus to fellow humans. Public places such as stations are one of the locations that may produce single-use masks as personal protective equipment waste. This study aimed to plan the most appropriate type of infectious waste container for disposable masks. Storage with the addition of ultraviolet lamp technology is one way to increase virus removal efficiency compared with no further processing. In this study, it was estimated that the most appropriate container volume is with a capacity of 50 L per station. The collection must be done every 24 hours; the estimated cost for one container can reach IDR 1,988,900. This planning can reduce the amount of mask waste used for the environment and reduce the burden applied to these places at the end.

Abstract

The COVID-19 pandemic is a global outbreak that also changes the generation of medical waste in hospital. The increasing number of people infected with the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) virus indirectly requires the management of infectious waste from patients to be safe and not have the potential to spread. The purpose of this study was to analyze the medical waste management in a hospital located in Jakarta City, Indonesia. This study employed direct observation and used secondary data in the analysis. Meanwhile, to determine the effect of the population infected with SARS-Cov-2 on medical generation, One Way ANOVA analysis was used. Data from May, 2020 showed that medical waste generation increased from 25.6 kg/month to 192.3 kg/month. The ANOVA significance test showed a value of 0.013; this indicates that the number of the infected population significantly affects the generation of medical waste. Medical waste that found during a pandemic becomes more complex, including hazmat clothes, masks, gloves, medical headgear, used bandages, injection and infusion equipment, eating and drinking utensils for patients exposed to COVID-19, and used swab and rapid test equipment.

Abstract

Indonesian marine debris of aquatic waste in Jakarta is managed by the UPK of the Water Agency, one of which is the Pluit Employment. Several composting methods can be used and adapted to the available circumstances and needs. The composting process is carried out by utilizing the supply of oxygen, nutrients, water, and temperature control. This study aims to analyze the selection of alternative composting systems that can be carried out for planning the composting unit at Pluit Employment. Selection analysis was carried out using the Utility Theory and Compromise program methods. Alternative 1: This alternative uses a composting system using an open bin. Alternative 2 uses a simple windrow system with garbage piled up without heavy equipment during operation. Alternative 3 uses a composting system with a static pile system with a machine turning it over. In the composting method chosen, alternative 2. The distance between compost for workers' movement space, it can reach 1 m as in the TPS 3R Technical instructions, that because it does not use machines, the land used for machine movement is reduced. Limited land can be utilized for the amount of windrow so that the amount of processed waste can be more significant.

Abstract

Waste management at tourist sites is an unavoidable problem due to the massive number of visitors. One of the types of waste is polyethylene terephthalate (PET) plastic bottles. This study aims to analyze the potential use of PET for waste to energy in tourist areas. This research was conducted in a tourist area in Klungkung Regency, Bali Province. This study only uses grab sampling in measuring waste generation and composition. This research was conducted by proximate analysis and thermal gravimetry analysis (TGA). The measurement of waste generation shows that the PET produced is 1.24 kg/day, or about 43.5% of the total waste generation. Proximate analysis measurements show the value of moisture, ash, volatile, and fixed carbon content, which are 1.53, 0.14, 95.92, and 2.42, respectively. Meanwhile, the caloric value of PET waste is 22.71 MJ/kg. The residue from the TGA results showed 2.575%. The thermal degradation process starts at a temperature of 280ᵒC, and the initial temperature of degradation starts at 406 – and ends at 468ᵒC. Utilization of PET waste at this tourist location can also help the purpose of waste management in Klungkung Regency, namely implementing the Waste to Energy concept at the Local Waste Processing Facility (TOSS).

Abstract

Central Java is one of the regions in Indonesia with a lot of water resources that must be appropriately managed. In addition, metal content in water bodies in Central Java must now be assessed to prevent health impacts that may be measurable. One of the methods to analyze the management of water bodies is the water quality index method. This study aimed to examine the water quality index due to metal contamination in water bodies in Central Java. Metal measurements were carried out using the AAS (Atomic Absorption Spectrophotometry) method. The value of the water quality index using the water quality index method for waters in Central Java in 2015-2018 was categorized to mild to moderately polluted, and only 2 locations were measured as heavily polluted. Two areas that are included in the heavily polluted category were the waters of Bulakan and Bojonegoro in 2016. To determine the cause of why the water quality index value being classified as moderately polluted and lightly polluted, we must look at the metal parameters that contribute the most to the index value. These parameters can be initial information on the pollutant source that causes pollution.

Abstract

Drainage is one way of removing unwanted excess water in an area and dealing with the effects of excess water in the system. When the rainy season comes, there are almost floods or puddles on urban roads. The large population also makes the volume of drainage channels fill up quickly, while the drainage capacity tends to decrease due to rainwater (erosion) and sedimentation. Meteorological Street, Laut Dendang Village, Percut Sei Tuan sub-district, Deli Serdang Regency, is one of the villages that is frequently flooded every time it rains. On these issues, the researcher highlights the importance of evaluating the Deli Serdang Regency's drainage system along Meteorological Road to anticipate when the rainy season comes. The general exponential method can determine whether the existing drainage volume can still accommodate terrestrial run-off and domestic wastewater in the next 30 years and calculate the population growth. Based on the research results from rainfall data obtained from Meteorology Road, the rainfall intensity value for the last ten years (2010 - 2019) was 10.538 mm/day. Thus, the amount of discharge flowing in the drainage channel (Qplansning) is equal to 0.832 m3/sec, while the planned Q for the next ten years is 0.874 m3/sec, for the next 20 years is 0.953 m3/sec, and 30 years into the future. front is 1.111 m3/sec. Based on the calculation results, Qplans exceeds Qeksisting. Therefore, a new channel plan is needed.

Abstract

Most of the area in Klungkung Regency has a waste management system that needs to meet technical requirements regarding the compartment, sorting, collecting, transporting, and processing. Coverage of handling urban waste is still far from the target of 80% in 2019 (46% in 2013), and the amount of waste generation that is still recycled is still minimal (4.95 m3 in 2017). This research aims to make a master plan or strategy implemented to improve service coverage and the quality of solid waste management in the future. This research was conducted by conducting a direct survey and secondary data collection. The strategy adopted is to increase the utilization of waste infrastructure and facilities; increasing the capacity of solid waste facilities according to service targets; improving the quality of landfill management in the direction of sanitary landfills; developing regional final processing site management, and applying waste handling technology that is appropriate and environmentally friendly. The Millennium Development Goals (MDGs) contain the seriousness of improving sanitation conditions, which require increased public access to sanitation facilities in half of the population without access to sanitation. Increased population access to proper sanitation (domestic wastewater, solid waste and environmental drainage) to 100% at the level of basic needs.
