Abstract

The problem of waste, especially household (organic) waste that has not been processed properly is certainly a big problem. The reason is because the waste management system and handling are not well organized. One solution in handling household waste (organic) can be done through composting using biopori infiltration holes and composter media. This study aims to determine the percentage of waste reduction, as well as to determine the comparison of compost yields from the two composting media. The study used 2 reactors in both composting media, with different initial waste weights. The composter uses variations in the initial weight of 3 kg and 4 kg of waste, while in the biopori using variations in the initial weight of waste 2 kg and 1 kg. The results of the percentage of waste reduction obtained from each reactor in the biopore are 50%, 25%, while in the composter are 63%, 50%. In the results of the percentage of waste reduction the best is found in the composting media with a composter. The compost quality parameters tested included pH, moisture content, C-organic, N-total, C/N ratio. The results show that the compost quality in the two composting media is closest to SNI 19-7030-2004 is composting media using a composter.

Abstract

Sampah plastik telah menjadi permasalahan lingkungan yang mendesak. Menurut data dari Kementerian Lingkungan Hidup dan Kehutanan pada tahun 2021, total sampah yang dihasilkan mencapai sekitar 68,5 juta ton, dengan sekitar 11,6 juta ton atau sekitar 17% dari total tersebut adalah sampah plastik. Metode konvensional dalam pengolahan sampah plastik, seperti landfill dan open dumping, berdampak negatif terhadap lingkungan. Pembakaran plastik juga berkontribusi pada polusi udara. Daur ulang plastik hanya mengubahnya menjadi bentuk yang berbeda tanpa mengurangi jumlah sampah plastik secara keseluruhan. Oleh karena itu, diperlukan metode alternatif, dan salah satu metodenya adalah pirolisis. Pirolisis adalah proses yang mendegradasi material pada suhu antara 300C dan 1000C, menghasilkan gas yang dikondensasi dan dipecah menjadi minyak, meninggalkan arang. Berbagai faktor seperti komposisi material, suhu, waktu tinggal, dan ukuran bahan baku memengaruhi proses pirolisis. Penelitian ini bertujuan untuk mengembangkan teknologi pirolisis yang ramah lingkungan untuk mengubah sampah plastik menjadi bahan bakar alternatif berbasis minyak, mengevaluasi kualitas produk minyak, dan mengidentifikasi jenis sampah plastik yang cocok untuk pirolisis. Hasil penelitian menunjukkan bahwa pirolisis sampah plastik LDPE pada suhu 800C menghasilkan minyak dengan sifat yang mendekati standar bensin dan solar Pertamina.

Abstract

Air tanah berfungsi sebagai salah satu sumber utama air minum dan memerlukan pengelolaan yang tepat; namun, kualitasnya sering menurun akibat keberadaan partikel tersuspensi atau Total Suspended Solids (TSS) yang terbawa saat air dipompa dari lapisan tanah. Tingginya kadar TSS dalam air dapat menurunkan tingkat kebersihan, menimbulkan bau tidak sedap, dan memicu pertumbuhan mikroorganisme. Selain itu, endapan partikel tersuspensi dapat menyumbat saluran air dan mempercepat kerusakan instalasi sanitasi, sehingga menurunkan kualitas kebersihan lingkungan. Riset ini bertujuan untuk menganalisis pengaruh variasi komposisi dan suhu sintering membran keramik terhadap efektivitas filtrasi dalam menurunkan konsentrasi TSS pada air tanah, serta menentukan kinerja membran yang paling optimal berdasarkan penurunan TSS dan laju filtrasi. Penelitian dilakukan menggunakan variasi rasio komposisi tanah liat:zeolit:arang sekam padi (85:10:5 dan 80:10:10) serta suhu sintering 900 °C dan 850 °C. Pengambilan sampel dilakukan pada menit ke-0 dan menit ke-60 selama proses filtrasi. Efisiensi penurunan TSS tertinggi (100%) dicapai oleh membran dengan komposisi 85:10:5 dan suhu sintering 900 °C.

Abstract

Pengelolaan sampah plastic di Kota Surabaya menghadapi tantangan besar dengan timbulan sampah yang diproyeksikan mencapai 660 ribu ton pada tahun 2025, di mana 16,51% di antaranya merupakan sampah plastik. Penelitian ini bertujuan untuk menganalisis perbandingan produk pirolisis dari kombinasi sampah plastik Polyethylene Terephthalate (PET) dan Low Density Polyethylene (LDPE) menggunakan katalis zeolit alam seberat 10 gram sebagai upaya mendukung circular economy. Proses pirolisis dijalankan selama 60 menit dengan variasi suhu operasi 400℃ dan 600℃ serta berbagai variasi fraksi komposisi campuran. Hasil penelitian menunjukkan bahwa rendemen minyak tertinggi diperoleh pada perlakuan TA4 (PET 0% : LDPE 100% pada suhu 400℃) yaitu sebesar 91,5%, sedangkan rendemen terendah diperoleh pada perlakuan TG6 (PET 100% : LDPE 0% pada suhu 600℃) sebesar 6,7%. Kenaikan suhu hingga 600℃ memicu terjadinya secondary cracking yang mengubah fraksi cairan menjadi gas non-kondensabel sehingga menurunkan rendemen minyak. Minyak pirolisis yang dihasilkan memiliki karakteristik fisik dengan nilai densitas berkisar antara 0,745 – 0,922 g/mL (rata-rata 0,815 g/mL), nilai viskositas berkisar antara 1,10 – 4,20 cP (rata-rata 2 cP), dan nilai kalor berkisar antara 26,50 – 44,80 MJ/kg (rata-rata 35,90 MJ/kg). Karakteristik fisik produk ini secara umum telah mendekati standar baku mutu bahan bakar komersial cair. Berdasarkan Cost Benefit Analysis (CBA) skala laboratorium, diperoleh nilai Net Benefit negative sebesar -Rp 12.825 karena keterbatasan kapasitas reaktor (100 gram). Walaupun demikian, teknologi ini memiliki potensi keberlanjutan yang besar apabila dilakukan peningkatan skala (upscaling) produksi.
