PEMANFAATAN KULIT SINGKONG SEBAGAI BAHAN KEMASAN RAMAH LINGKUNGAN DENGAN VARIASI PENAMBAHAN SERAT DAUN NANAS Adlan, Muhammad Fariz Penggunaan kemasan berbasis polistirena (Styrofoam) yang sulit terdegradasi mendorong pengembangan kemasan ramah lingkungan berbasis bahan hayati. Penelitian ini bertujuan menganalisis pengaruh penambahan serat daun nanas terhadap karakteristik Kemasan ramah lingkungan berbasis limbah kulit singkong. Penelitian menggunakan metode eksperimen dengan variasi penambahan serat daun nanas sebesar 0%, 5%, 10%, dan 20%. Kemasan ramah lingkungan dibuat menggunakan metode thermopressing pada suhu 160 °C dan tekanan 4 MPa, kemudian diuji kuat tarik, kuat tekan, daya serap air, dan biodegradasi. Hasil penelitian menunjukkan bahwa peningkatan kadar serat daun nanas meningkatkan kuat tarik dari 0,130 menjadi 0,805 MPa dan kuat tekan dari 0,003667 menjadi 0,013800 MPa, serta menurunkan daya serap air dari 13,667% menjadi 7,667%. Perlakuan dengan penambahan serat 20% menghasilkan karakteristik Kemasan ramah lingkungan terbaik, meskipun persentase biodegradasi menurun menjadi 22,377%. Temuan ini menunjukkan bahwa serat daun nanas berpotensi berpeluang dikembangkan sebagai alternatif kemasan yang lebih ramah lingkungan.; The use of polystyrene (Styrofoam) packaging, which is difficult to degrade, has encouraged the development of environmentally friendly bio-based packaging materials. An experimental method was employed using pineapple leaf fiber contents of 0%, 5%, 10%, and 20%. The Eco-friendly packaging was produced using the thermopressing method at 160 °C and 4 MPa, and was evaluated for tensile strength, compressive strength, water absorption, and biodegradability. The results showed that increasing the pineapple leaf fiber content improved tensile strength from 0.130 to 0.805 MPa and compressive strength from 0.003667 to 0.013800 MPa, while reducing water absorption from 13.667% to 7.667%. The treatment containing 20% pineapple leaf fiber produced the best Eco-friendly packaging characteristics, although the biodegradation rate decreased to 22.377%. These findings indicate that pineapple leaf fiber has the potential to improve the mechanical properties of cassava peel waste-based Eco-friendly packaging, making it a promising environmentally friendly packaging alternative.

Hasil DED dengan estimasi biaya Rp399.790.720,00 mencakup perencanaan teknologi screening, klorinasi, grease trap, serta pengolahan anaerob-aerob bermedia sarang tawon untuk parameter yang melebihi baku mutu. Penelitian ini menyimpulkan bahwa rancangan mampu mengatasi overflow, mengoptimalkan penyisihan polutan, dan menjamin operasional IPAL yang berkelanjutan sebagai cetak biru infrastruktur sanitasi di PT Pertamina Kawasan Simprug.; The PT Pertamina (Persero) Simprug complex is a private mixed-use area experiencing effluent quality exceedances, hydraulic failures, and operational problems at the existing WWTP. This research aims to evaluate the existing WWTP and project wastewater discharge, and to formulate a DED that meets the Regulation of the Minister of Environment and Forestry No. 11 of 2025. The research method involved field observation, evaluation, and DED planning with a capacity of 418.7 m³/day. The DED results, with an estimated cost of Rp399,790,720.00, include screening, chlorination, grease traps, and honeycomb anaerobic-aerobic biological treatment for parameters exceeding standards. This study concludes that the design addresses overflow issues, optimizes pollutant removal efficiency, and ensures sustainable WWTP operations, serving as a sanitation infrastructure blueprint for the PT Pertamina Simprug Complex.

Perancangan Rotating Biological Contactor dalam Penyisihan Biochemical Oxygen Demand Air Limbah Peternakan Sapi Romadhona, Ananda Kartini Sugiatik Air limbah peternakan sapi yang terdiri dari urin, sisa kotoran hewan, sisa pakan, air pencucian, serta air domestik mengandung nilai BOD yang cukup tinggi sehingga berpotensi mencemari lingkungan. Rotating biological contactor adalah alat pengolahan biologi yang memanfaatkan attached growth untuk menyisihkan BOD. Penelitian bertujuan untuk merancang unit RBC sebagai teknologi pengolahan air limbah peternakan sapi untuk menurunkan kadar BOD. Variasi yang digunakan adalah luas area terendam 30%, 50%, dan 70%. Variasi luas area terendam 30% menghasilkan kinerja penyisihan BOD terbaik dengan konsentrasi BOD akhir sebesar 99,84 mg/L sehingga telah memenuhi baku mutu air limbah berdasarkan Permen LH Nomor 5 Tahun 2014. Hal ini dikarenakan luas area terendam tersebut memberikan keseimbangan yang lebih baik antara kontak biofilm dengan air limbah dan paparan oksigen dari udara sehingga proses biodegradasi berlangsung lebih optimal dibandingkan variasi luas area terendam lainnya.; Cattle farm wastewater, consisting of urine, animal manure residues, feed residues, wash water, and domestic wastewater, contains relatively high Biochemical Oxygen Demand (BOD) concentrations, posing a potential risk of environmental pollution. The Rotating Biological Contactor (RBC) is a biological wastewater treatment technology that utilizes an attached-growth process to remove BOD. This study aimed to design an RBC unit as a treatment technology for cattle farm wastewater to reduce BOD concentrations. The reactor was operated with three submerged area variations: 30%, 50%, and 70%. The 30% submerged area achieved the best BOD removal performance, resulting in a final BOD concentration of 99.84 mg/L, which complied with the wastewater quality standard stipulated in the Indonesian Minister of Environment Regulation No. 5 of 2014. This result was attributed to the 30% submerged area providing a more favorable balance between biofilm contact with wastewater and oxygen exposure from the air, thereby promoting a more efficient biodegradation process than the other submerged-area variations.

Pemanfaatan Selulosa Bakteri sebagai Penguat Honeycomb Paper Wrap Berbasis Limbah Pelepah Pisang FAUZI, FAHRIZIL Peningkatan penggunaan kemasan plastik pada sektor e-commerce mendorong pengembangan material kemasan ramah lingkungan berbasis sumber daya terbarukan. Penelitian ini bertujuan mengevaluasi efektivitas selulosa bakteri hasil fermentasi limbah cair tahu sebagai bahan penguat pada honeycomb paper wrap berbasis pulp pelepah pisang. Penelitian menggunakan empat perlakuan berdasarkan variasi komposisi pulp pelepah pisang dan selulosa bakteri, yaitu P0 (100:0), P1 (90:10), P2 (80:20), dan P3 (70:30). Karakterisasi meliputi sifat fisik, mekanik, dan morfologi. Hasil penelitian menunjukkan bahwa penambahan selulosa bakteri membentuk struktur serat yang lebih kompak melalui jaringan nanofibril yang mengisi ruang antar fiber, sehingga meningkatkan densitas, menurunkan porositas, serta memperbaiki sifat mekanik dan kapasitas menahan beban. Perlakuan P3 menghasilkan karakteristik terbaik dan melampaui kertas komersial pada sebagian besar parameter yang diuji. Hasil penelitian menunjukkan bahwa kombinasi pulp pelepah pisang dan selulosa bakteri berpotensi menghasilkan material kemasan berbasis serat non-kayu yang lebih ramah lingkungan.; The increasing use of plastic packaging in the e-commerce sector has encouraged the development of environmentally friendly packaging materials as an alternative to conventional plastic packaging. This study aimed to evaluate the effectiveness of bacterial cellulose produced through the fermentation of tofu wastewater as a reinforcing material in honeycomb paper wrap made from banana pseudostem pulp. The study employed four pulp composition treatments consisting of banana pseudostem pulp and bacterial cellulose, namely P0 (100:0), P1 (90:10), P2 (80:20), and P3 (70:30). The material characteristics were evaluated through physical, mechanical, and morphological analyses. The results showed that the addition of bacterial cellulose produced a more compact fiber structure through a nanofibril network that filled the spaces between fibers, thereby increasing density, reducing porosity, and improving mechanical properties and load-bearing capacity. The P3 treatment exhibited the best overall performance and outperformed commercial paper in most of the evaluated parameters. These findings indicate that the combination of banana pseudostem pulp and bacterial cellulose has considerable potential as an environmentally friendly non-wood-based packaging material.
