ANALISA PRODUKSI REFUSE-DERIVED FUEL (RDF) DENGAN METODE BIODRYING DAN MEKANIKAL DARI SAMPAH MENGGUNAKAN SISTEM DINAMIS
Full text linkBandung Regency in 2023 built a TPST (Integrated Waste Management Site) with a capacity of 75 tons/day with the mechanical method "One Day Process" and a capacity of 20 tons/day with the biological method "Biodrying". The fact is that the capacity was not realized according to plan. This study is to evaluate the differences between the Biodrying and One Day One Process methods in producing RDF (Refuse Derived Fuel) and to compile a dynamic model of waste management through sustainable RDF. This study was conducted using a dynamic system using Powersim software with simulations from 2023 to 2024. Existing management was modeled and analyzed with a dynamic system. The results of the study showed that the biodrying method was superior to the capacity and quality of RDF products and had operational cost savings for electricity needs. The modeling results showed that the performance of waste management from 2023 to 2034 was only 10.35 tons/day for the one day one process method and 9.8 tons/day for the biodrying method, as a result, unmanaged waste increased every year. To maximize capacity, the Bandung Regency regional government needs to intervene with policy steps that support the sustainability of TPST

GIS-based analysis of water quality risk factors and CKDu prevalence in Northern Yobe State, Nigeria
Full text linkChronic Kidney Disease (CKDu) presents a major public health challenge in Northern Yobe State, Nigeria, particularly in the Bade community, where water quality is overly suspected to influence its prevalence. This study employs a Geographic Information Systems (GIS)-based framework to analyze the spatial distribution of CKD in relation to water quality parameters. Advanced spatial analysis techniques, including hexagonal tessellation and Moran's I for spatial autocorrelation, were utilized alongside community-based surveys conducted using Kobotoolbox and Qfield applications to map CKD hotspots. The Moran's I Index of 0.1046, with a z-score of 4.9546 and a p-value of 0.000001, indicates significant clustering of CKD cases rather than random distribution across the study area. Water samples from 30 water facilities, with 10 from each classified hotspot, were analyzed for nephrotoxic heavy metals, ionic concentrations, and hardness using an Atomic Absorption Spectrometer (Model 210V-GP). The spatial distribution of these parameters was modeled using Inverse Distance Weighting (IDW) interpolation in ArcGIS Pro 3.4. Descriptive statistics, hazard index calculations, and Water Quality Index (WQI) assessments were conducted, with box plots facilitating comparative analysis across High, Medium, and Low disease areas. ANOVA and Tukey's HSD post-hoc tests were performed to compare specific water parameters between the disease hotspots and water facilities. The results revealed elevated concentrations of nephrotoxic heavy metals in high-disease hotspots, with maximum values observed for Arsenic (0.21 mg/L), Cadmium (0.30 mg/L), Lead (0.23 mg/L), Chromium (0.50 mg/L), and Fluoride (55 mg/L). Additionally, Nitrite and Nitrate levels exhibited high Hazard Quotients, all surpassing WHO guidelines for safe drinking water. These findings underscore the potential health risks posed by these contaminants in affected areas. Results demonstrate a significant link between the prolonged use of handpumps water and high prevalence of chronic kidney disease incidence (CKD) among affected households. Additionally, the study identified strong spatial correlations between CKD incidence and high concentrations of nephrotoxic heavy metals in water from handpumps, providing critical insights for targeted public health interventions and guiding future research efforts
Indonesian green tides: the problem is also the solution
Full text linkGreen tides are unattached blooms of green macroalgae (seaweeds) that occur globally and can attain vast proportions. The main components of the blooms are species of the sea lettuce genus Ulva, a sheet-like green seaweed, which can form unusual morphs under these conditions (Blomster et al., 2002). In estuaries and shallow coastal embayments drifting or cast-up macroalgae can reach quantities of up to 27 kg wet weight m-2. Green tides have been researched extensively since Fletcher's (1996) review highlighted their importance, but they came to wide public attention at the time of the 2008 Qingdao Summer Olympics when the Yellow Sea blooms endangered the sailing events. In May–July 2008, prior to the Olympics, the Yellow Sea coastline experienced the world’s largest green tide with 1 million tonnes of drifting biomass covering 13,000–30,000 km2 (Leliaert et al., 2008). Enormous quantities were washed into shallow water and onto the beaches. News reports from the time show volunteers working to remove the biomass and save the events. Green tides have increased in frequency and extent globally over the last few decades, with the most significant blooms continuing to be those in the Yellow Sea (Ye et al., 2011; Ren et al., 2024)

Full text linkABSTRAK Tanah-tanah yang tidak didayagunakan seringkali dijumpai diduduki oleh masyarakat secara begitu saja dan dalam jangka waktu lama. Dalam kenyataanya, diatas lahan tersebut terdapat subjek pemegang hak nya yaitu Pemerintah, masih banyak kasus-kasus dalam bidang pertanahan mengenai penguasaan aset Pemerintah oleh masyarakat dan telah menempati dalam kurun waktu cukup lama dan berpuluh-puluh tahun dan secara fisik sudah dikuasai oleh masyarakat sejak lama tanpa kejelasan status hak nya di atas lahan milik aset Pemerintah. Penelitian ini bertujuan untuk mengetahui dan menganalis aset tanah Pemerintah Daerah yang dididuduki oleh masyarakat ditinjau dari persfektif Hukum Pertanahan dan penyelesaian sengketa atas tanah Pemerintah Daerah yang dididuduki oleh masyarakat ditinjau dari persfektif Hukum Pertanahan. Penulis melakukan penelitian dengan menggunakan metode penelitian normatif yang bersifat deskriptif analitis yaitu mengumpulkan fakta-fakta yang ada dan menganalisis peraturan-peraturan yang berlaku dikaitkan dengan teori hukum dan praktek mengenai hukum agraria nasional. Tahap penelitian dilakukan melalui Penelitian Kepustakaan dan Penelitian Lapangan. Hasil penelitian menunjukkan bahwa, Pertama, aset Pemerintah yang diduduki oleh masyarakat ditinjau dari persfektif Hukum Pertanahan bahwa masyarakat belum mempunyai status hak terhadap tanah aset pemerintah yang diduduki oleh Masyarakat. Maka dalam hal ini, masyarakat tidak dapat menguasai, menggunakan, memanfaatkan tanah di atas aset Pemerintah. Pembiaran terhadap aset oleh Pemerintah disebabkan kurangnya pengawasan dan pengelolaan serta anggaran dan sumber daya manusia yang dapat menghambat kemampuan pemerintah untuk mengelola aset secara efektif. Kedua, Penyelesaian sengketa atas tanah aset Pemerintah yang didiuduki oleh masyarakat melalui mediasi sangat dirasakan manfaatnya dan para pihak telah mencapai kesepakatan yang mengakhiri persengketaan secara adil dan saling menguntungkan. BPN sebagai mediator yang netral yang tidak memiliki kewenangan untuk mengambil keputusan dalam menyelesaikan sengketa hak atas tanah melalui mediasi kewenangan diserahkan sepenuhnya kepada para pihak berdasarkan kesepakatan. Kata Kunci: Sengketa Tanah, Aset Pemerintah dan Masyakat ABSTRACT Regulations regarding unused land are often fulfilled by the community casually and over a long period of time. In fact, on this land the subject holder of the rights is the Government, there are still many cases in the land sector regarding control of Government assets by the community and have been occupied for quite a long period of time and for decades and have been physically controlled by the community for a long time. . without clarity regarding the status of their rights to land belonging to Government assets. This research aims to determine and analyze Regional Government land assets occupied by the community from a Land Law perspective and complete settlement of Regional Government land occupied by the community from a Land Law perspective. The author conducted research using normative research methods which are descriptive analytical in nature, namely collecting existing facts and analyzing applicable regulations related to legal theory and practice regarding national agrarian law. The research stage was carried out through library research and field research. The research results show that, firstly, government assets controlled by the community are viewed from a Land Law perspective, meaning that the community does not yet have rights to government land assets controlled by the community. So in this case, the community cannot control, use or exploit land on Government assets. The government's neglect of assets is caused by a lack of supervision and management as well as budget and human resources which can hamper the government's ability to manage assets effectively. Second, the settlement of government land assets occupied by the community through mediation has been very beneficial and the parties have reached an agreement that ends the dispute in a fair and mutually beneficial manner. BPN as a neutral mediator who does not have the authority to make decisions in resolving land rights through mediation, the authority is completely transferred to the parties based on the agreement. Keywords: Land Disputes, Government and Community Asset
