Abstract

Penelitian ini bertujuan untuk mengetahui (1) kadar hemoglobin pada darah pasien penderita gagal ginjal kronik, (2) persentase penderita gagal ginjal kronik yang megidap anemia. Adapun  subjek dari penelitian ini adalah pasien penderita gagal ginjal koronik (GGK), sedangkan Objeknya adalah kadar hemoglobin darah pasien penderita GGK. Data diperoleh dengan mengukur sampel darah pasien penderita gagal ginjal kronik (GGK) dengan menggunakan alat Sysmex KX-21. Jumlah pasien penderita GGK yang diukur sampel darahnya   sebanyak 23 orang (7 orang wanita dan 16 orang laki-laki) Data dianalisis menggunakan metode deskriptif. Hasil analisis penelitian ini menunjukkan, bahwa rentangan kadar hemoglobin dalam darah pasien penderita GGK wanita adalah 3 – 8 g/dL, sedangkan pada laki-laki 5 – 12 g/dL. Persentase penderita GGK yang mengidap anemia adalah 100%, dengan rincian masing-masing 2 orang mengidap anemia berat dan ringan, sedangkan yang lainnya (19 orang) mengidap anemia sedang. Anemia terjadi karena fungsi ginjal pada penderita GGK tidak bekerja dengan baik, sehingga ginjal kurang mampu  fungsi ginjalnya tidak bekerja dengan baik, termasuk dalam memproduksi hormon eritropoeitin, yang berfungsi dalam pembentukan sel darah merah. Berkurangnya produksi hormon tersebut menyebabkan produksi sel darah merah menjadi berkurang, sehingga secara langsung menyebabkan menurunya kadar hemoglobin dalam darah.Kata Kunci: gagal ginjal kronik, hormon eritropoeitin, kadar hemoglobin, anemia.

Abstract

Artisanal and Small-Scale Gold Mining (ASGM) in Pelangan Village, Sekotong District, West Lombok, Indonesia, provides significant economic benefits but poses severe environmental and social challenges. This study aims to identify ASGM practices, operational scales, and distribution patterns while analyzing their impacts on social, economic, and ecological aspects, particularly mangrove ecosystems. Using Sentinel-2 L2A satellite imagery and NDVI analysis to assess mangrove health, combined with a Systematic Literature Review (SLR) following PRISMA guidelines, the research synthesized data from 25 relevant articles published between 2009 and 2024. The findings indicate that ASGM contributes to local income but fosters unsustainable economic dependency, with mercury (Hg) contamination in rivers exceeding WHO thresholds and persistent pollution undermining mangrove functions. Socially, ASGM heightens health risks, including anemia and heavy metal bioaccumulation in local communities. Despite some improvements in mangrove health from 2017 to 2024, significant environmental degradation remains. Mitigation strategies such as biochar application and bioremediation, alongside sustainable resource management and community empowerment, are essential to reducing environmental damage while supporting local livelihoods, aligning with SDG 13 (Climate Action) and SDG 14 (Life Below Water)

Abstract

This research discusses the application of the balance principle in laboratory waste management as a strategy to minimize environmental impacts. This principle aims to balance laboratory activities and environmental protection by reducing waste at the source, sorting it out, and using environmentally friendly waste processing technology. The research used a descriptive qualitative approach in the Mataram University laboratory. The research results show that applying the balance principle is still not optimal due to limited understanding, infrastructure and adequate policy support. Recommended strategies include implementing the 3R principle (Reduce, Reuse, Recycle), selecting safer chemicals, and increasing training and preparing clear SOPs. Waste identification reached (50%), with limitations in storage (44%) and transportation (43%). Management and final disposal were minimal (33% and 38%), increasing environmental risks. Documentation, reporting (43%), and regulatory compliance (43%) still need to be improved. The K3 aspect is quite good (54%), but emergency response procedures are still weak. Sustainable management (37%) and environmental monitoring (43%) lack effort in mitigating environmental impacts. Applying the principle of balance is important to achieve sustainable laboratory waste management.

Abstract

Hazardous and Toxic Waste (B3) from laboratories, especially those containing heavy metals (Hg and Cr) and several physical factors such as pH, TSS, and color, poses a serious threat to the environment if not managed properly. This study aims to estimate the adsorbent for the development of laboratory-scale wastewater treatment equipment based on the adsorption method using biochar, zeolite, and activated alumina. The research method involves preparing adsorbent materials, testing their effectiveness in reducing the content of heavy metal pollutants, and designing a waste treatment device. The combination of biochar, zeolite, and activated alumina was chosen due to their complementary abilities in removing heavy metal content from B3 waste in the Soil Chemistry laboratory. The treatment results showed significant reductions (p < 0.05) in heavy metal (Hg and Cr) levels in laboratory waste. The optimal combination is a formulation of biochar, zeolite, and activated alumina (1:1:1). Innovations in adsorbent technology for processing heavy metal waste in soil chemistry laboratories can be applied and further developed to create a clean and healthy environment.
