Abstract

The generation of polyethylene terephthalate (PET) plastic and garden waste must be recycled to support the circular economy. An alternative way to reduce the plastics waste is to reduce this waste by converting it into energy such as Refused Derived Fuel (RDF) as an alternative for processing waste. Substitution of plastic and garden waste is an opportunity to be analyzed. Hence, This study aimed to investigate the potential for converting material substitution from PET and garden waste into RDF. The RDF characterized test method was carried out by proximate, water content, ash content, and analysis. At the same time, the calorific value. was tested by bomb calorimetry. Substitution of the mixture of plastic and garden waste affects each parameter of RDF pellet quality including water, ash, and caloric value (sig.< 0.05). The increase of plastic waste in pellets consistently increases the calorific value of RDF from 18.94 until 25.04 MJ/kg. The RDF pellet water and ash content also invariably affect the rate of increase in the calorific value of RDF in the multilinearity model (sig.<0.05; R2 is 0.935). The thermal stability of the pellets occurred at a temperature of 5000C decomposition of hemicellulose, cellulose, and lignin in mixed garden waste with plastic in RDF pellets. The decrease in the decomposition of PET into terephthalic acid monomer from the thermal stability of raw materials and waste PET plastic pellets occurs at a temperature of 4500ËšC. This potential finding can be used as a basis for consideration in regions or countries that have the generation of garden waste and plastic, especially the type of PET to be used as an environmentally friendly fuel.

Abstract

Lake Rawa Pening, in Semarang Regency, is one of the super lakes of revitalization priority. Lake revitalization is an activity to restore the natural function of the lake as a water reservoir through lake dredging, cleaning of invasive alien plants, and land use planning. This makes land use and land cover information in Lake Rawa Pening useful for formulating policy strategies related to revitalization. This study will discuss land cover mapping in Lake Rawa Pening. Mapping using Landsat 9 Imagery and machine learning on Google Earth Engine (GEE). Machine Learning used in this study is CART and RF. The research result shows that the land cover map with the best accuracy is obtained from machine learning RF with an overall accuracy of around 0.78, while CART machine learning is approximately 0.76. The overall accuracy values for CART and RF are not much different because they are both decision tree-based machine learning. This research needs to be developed using cloud masking, comparing image transformations, and comparing its predecessor data, namely Landsat 8. This is useful for providing representative land cover data as the basis for the policy of revitalizing Lake Rawa Pening.

Abstract

The Tanggul River in Surakarta City is a tributary that empties into the Bengawan Solo River. Domestic activities located on river borders can pollute with the waste generation. Therefore, managing waste sources such as storage and collection is crucial in waste management. This study aims to analyze waste management from river debris storage and collection around the study site. The technique used in this research is direct observation of the study area and performing a decision analysis for alternative processing. Decision support system has one model, namely Multi-Criteria Decision Making for environmental development. The activities for collecting and sorting river debris in the Tanggul River are not yet available. The existing river debros collection used a 7 cm diameter net that has been installed at the sluice gate of the Tanggul River. Considering aspects or criteria in implementing accommodation activities needs to be carried out before determining the best alternative. Therefore, several measures need to be considered in determining the container based on SNI 19-2454-2002 concerning Operational Procedures for Urban Waste Management and Minister of Public Works Regulation Number 3 of 2013. The collection activity in alternative 1 uses the Brute Boom system: Heavy Duty Containment Boom equipped with a galvanized weir mesh net attached under the boom. The collection activity in alternative 2 uses a floating cube. The floating cube is a cube-shaped Waste holder that can float in the river to effectively hold waste floating on the surface of the river body. It is imperative to prevent river pollution from activities by providing infrastructure for storing and collecting waste. However, it does not have a more significant impact, such as the Tanggul River to the Bengawan Solo River in Surakarta City.

Abstract

Di tengah meningkatnya bencana lingkungan seperti banjir rob dan masalah luas sampah laut, peningkatan kapasitas adaptasi masyarakat menjadi sangat penting. Penelitian ini menyelami tantangan kritis dalam meningkatkan mekanisme adaptasi lokal terhadap bencana lingkungan tersebut, dengan fokus khusus pada peningkatan kesiapsiagaan masyarakat melalui implementasi strategis Sistem Peringatan Dini (EWS). Dengan menggunakan pemeriksaan rinci terhadap kondisi saat ini bersamaan dengan analisis SWOT (Kekuatan, Kelemahan, Peluang, Ancaman) yang komprehensif, studi ini secara teliti menilai tingkat kesiapan teknologi, infrastruktur, dan sosial komunitas dalam menghadapi bencana tersebut. Penyelidikan ini mengungkapkan kebutuhan mendesak untuk EWS yang terintegrasi dengan mulus, yang ditandai dengan kekuatan signifikan seperti potensi teknologi yang muncul dan kesadaran yang meningkat dalam komunitas. Meskipun memiliki kekuatan ini, studi ini menemukan tantangan berat, termasuk ketergantungan yang mencolok pada teknologi yang mungkin tidak dapat diakses secara universal dan adanya resistensi di antara segmen tertentu dari populasi. Mengingat peluang yang disajikan oleh kebijakan pemerintah yang mendukung dan kemajuan teknologi, di tengah ancaman seperti perubahan iklim yang tidak dapat diprediksi dan kekhawatiran atas keamanan data, penelitian ini mengusulkan model implementasi EWS yang inklusif dan kolaboratif. Studi ini menyimpulkan bahwa EWS, ketika diterapkan secara strategis melalui pendekatan partisipatif yang melibatkan semua pemangku kepentingan mulai dari komunitas lokal hingga badan pemerintah dan mitra teknologi, dapat berfungsi sebagai langkah efektif untuk menangkal bencana lingkungan. Pendekatan semacam itu tidak hanya memastikan ketahanan komunitas tetapi juga menumbuhkan budaya kesiapsiagaan dan kapasitas adaptasi yang esensial untuk mengurangi dampak tantangan lingkungan yang semakin sering dan parah ini. In the face of escalating environmental calamities such as rob flood disasters and the pervasive issue of marine debris, enhancing community adaptive capacities has never been more crucial. This research delves into the critical challenge of bolstering local adaptive mechanisms against these environmental disasters, focusing on elevating community preparedness through the strategic implementation of an Early Warning System (EWS). This study meticulously assesses communities ' technological, infrastructural, and social preparedness in confronting such disasters by utilizing a detailed examination of current conditions alongside a comprehensive SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis. The investigation reveals a compelling need for a seamlessly integrated EWS, underscored by considerable strengths such as the potential of emerging technologies and heightened awareness within the community. Despite these strengths, the study uncovers formidable challenges, including a marked dependence on technology that may not be universally accessible and the presence of resistance among certain segments of the population. Considering opportunities presented by supportive government policies and advancements in technology against a backdrop of threats like unpredictable climate changes and concerns over data security, the research proposes a model for EWS implementation that is both inclusive and collaborative. The study concludes that an EWS, when strategically deployed through a participatory approach that engages all stakeholders ranging from local communities to government bodies and technological partners can serve as an effective countermeasure to environmental disasters. Such an approach not only ensures the resilience of communities but also fosters a culture of preparedness and adaptive capacity that is essential for mitigating the impacts of these increasingly frequent and severe environmental challenges.

Abstract

River debris in Jakarta is generated in several locations by conventional transportation. Waste transportation with traditional models is usually not time-efficient, primarily when river debris is generated every time. Transport systems that can be used for river debris include compactor systems, pre-compactor systems, and baller systems. This research uses literature study and secondary data in determining alternatives. Meanwhile, the alternative selection was carried out using the Multi-Criteria Decision Making (MCDM) method. This study uses four criteria for selecting alternatives: initial capital, type of transport container, operation and maintenance, and processing capability. The utility value of waste transportation with compaction and pre-compacting systems does not significantly have utility values of 0.722 and 0.833, respectively. At the same time, the baller system has a utility value of 0.222. This shows that the compacted system is more suitable to be applied to SPA river debris in Jakarta. The presence of a pr-compactor can also reduce the water content in-river debris.

Abstract

The waste from the river is one of the obstacles in managing the Bengawan Solo River, Surakarta City. River debris is usually collected in tributaries so as not to carry the pollutant load to the watershed, causing flooding, and then transported to the Final Processing Site (TPA). This study aims to analyze the waste transportation system from the source to the landfill. This research was conducted by direct observation and using Multi-Attribute Utility Theory (MAUT) for determination. Alternative waste transportation used are haul container system (HCS) and stationary container system (SCS). The criteria used are the number of ritations, price, ease of transportation, potential damage, maintenance, and type of container. Based on the weighting results on the MAUT analysis, transportation with the SCS method has a higher weight than the HCS method.
