Abstract

The City of Jambi has three entering gateways for people from other places to get in using arterial roads. Two roads link Jambi City with South Sumatera, West Sumatera and also Riau Provinces, and one another connects to West Tanjung Jabung and East Tanjung Jabung Regencies. Many vehicles, starting from individual cars and motor cyclesuntil HDV with more dimensions such as trailer truck, have increased air pollution and would generate effect to human health. The research aimed to estimate the load emission from mobile sources on those gateways using Mobilev 3.0 software, and converted the results using Microsoft Excel for advance analysis. Data input came from the number of vehicles from General Sudirman Street, West Ring Road, Surya Dharma Street, South Ring Road, East Ring Road, and Yos Sudarso Street which was enumerated by direct observation using traffic counting method. The results showed that the highest emission (ton/year) to CO and HC was from General Sudirman Street and for CO2, NOx, PM10, and soot was from South Ring Road. The total average daily traffic (ADT) was 435,684.30 units of vehicles per 24 hours, which the biggest was in General Sudirman Street with 114,451.30 units of vehicles per 24 hours. Through this research, both the emission load and also the traffic load situation in each road could be described and became the important information on road transportation management related to ambient air pollution and greenhouse gases controlling.

Abstract

Jumlah timbulan sampah plastik di laut sebesar 521,540 ton, dikarenakan belum optimlanya pengolahan sampah plastik di darat. Hal ini menjadi perhatian khusus dalam pengolahan sampah plastik. Pengolahan sampah plastik salah satunya dilakukan dengan proses daur ulang (recycle). Salah satu jenis plastik yang dikeluhkan oleh banyak pemilik bank sampah karena tidak dapat dijual ke pengepul yaitu sampah plastik multilayer. Plastik multilayer merupakan plastik dilapisan bahan aluminium foil maupun bahan lainnya (multilayer). Pada umumnya, sampah plastik multilayer hanya di daur ulang menjadi prakarya seperti tas, sandal, dompet dan lain-lainl dengan tujuan memperlambat proses masuknya sampah plastik multilayer ke TPA. Oleh karena itu pada penelitian ini dilakukan proses daur ulang sampah plastik multilayer menjadi papan polimer. Dimana papan polimer ini dibuat dengan kombinasi sampah plastik HDPE sebagai matrik. Sampah plastik HDPE dan plastik multilayer dicacah, dan dicetak dan dipanaskan menggunakan hotpress. Untuk mendapatkan kualitas papan polimer yang baik perlu dilakukan penentuan komposisi yang tepat antara filler dan matrik. Penelitian ini bertujuan untuk menentukan komposisi efektif agar didapatkan kualitas papan polimer, dengan memvariasikan komposisi penyusun papan polimer dengan variasi (90%multilayer :10%HDPE), (50% multilayer :50%HDPE), (30% multilayer :70% HDPE) dan (10% multilayer: 90% HDPE). Hasil penelitian menunjukkan papan polimer dengan menunjukkan komposisi yang terbaik pada variasi 10% Multilayer: 90% HDPE) dengan nilai uji keteguhan patah sebesar 60 kgf/cm2, nilai uji kerapatan sebesar 0,94 dan nilai kadar air 0,6. Dari kualitas tersebut papan polimer yang dihasilkan belum memenuhi standar nasional indonesia untuk papan partikel. Namun papan dengan kualitas dapat digunakan sebagai bahan dasar untuk produk rumah tangga dengan kombinasi bahan lainnya.

Abstract

Plastik multilayer adalah limbah plastik yang banyak dikeluhkan oleh pemilik bank sampah, hal ini disebabkan plastik multilayer tidak dapat dijual ke pengepul. Salah satu pengolahan yang telah dilakukan yaitu mendaur ulang menjadi prakarya dengan tujuan memperlambat masuknya sampah plastik multilayer ke Tempat Pemprosesan Akhir (TPA). Oleh karena itu, dibutuhkan proses daur ulang menjadi material yang bersifat jangka panjang. Pada penelitian ini dilakukan proses daur ulang sampah plastik multilayer menjadi papan polimer menggunakan alat Hot press. Papan polimer dibuat dengan kombinasi sampah plastik HDPE sebagai matrik. Untuk mendapatkan kualitas papan polimer yang baik dilakukan penentuan komposisi yang tepat antara filler dan matrik. Pada penelitian ini akan divariasikan komposisi penyusun papan polimer. Selanjutnya untuk meningkatkan kualitas perlu ditambahkan zat adiktif berupa Maleic Anhydride (MAH) sebagai compatibilizer dengan variasi 5% dan 10 %. Hasil penelitian menunjukkan papan polimer dengan variasi 30% multilayer: 70% HDPE dengan penambahan MAH 10% memiliki nilai keteguhan tekan sebesar 90 kgf/cm3, nilai kerapatan tertinggi sebesar 1,16 gr/cm2, kadar air 0% dan daya serap air 0%. Hal ini menunjukkan bahwa komposisi limbah plastik multilayer dengan berat maksimal 30% dari berat keseluruhan dan penambahan MAH 10% memberikan hasil memenuhi SNI 03 – 2105 -2006.Penambahan MAH memberikan pengaruh dalam meningkatkan kualitas papan polimer. Kata Kunci : Plastik Multilayer dan Papan Polimer. Multilayer plastic is plastic waste that many waste bank owners complain about, this is because multilayer plastic cannot be sold to collectors. One of the processes that have been carried out is recycling into crafts with the aim of slowing down the entry of multilayer plastic waste into the Final Processing Site (TPA). Therefore, a long-term recycling process is needed. In this study, the process of recycling multilayer plastic waste into polymer boards was carried out using a hot press. Polymer board is made with a combination of HDPE plastic waste as a matrix. To get a good quality polymer board, it is done with the right composition between filler and matrix. In this study, the composition of the polymer board will be varied. Furthermore, to improve the quality of additives that need to be added in the form of Maleic Anhydride (MAH) as a compatibilizer with variations of 5% and 10%. The results showed that the polymer with 30% multilayer variation: 70% HDPE with the addition of 10% MAH had a compressive strength value of 90 kgf/cm3, the highest density value was 1.16 gr/cm2, 0% moisture content and 0% water absorption. This shows that the composition of multilayer plastic waste with a maximum weight of 30% of the total weight and the addition of 10% MAH gives results that meet SNI 03 – 2105 -2006. The addition of MAH has an effect in improving the quality of the polymer board. Keywords: Multilayer Plastic dan Polymer Board.

Abstract

Agricultural activities still involve the use of synthetic pesticides to support the increase of their products. On the other hand, the use of synthetic pesticides such as organochlorines and pyrethroids may contribute to the decline of aquatic ecosystem health due to the accumulation of their residues in sediments and organisms. The current study aimed to assess the levels of organochlorine and pyrethroids pesticide residue in endemic fish and sediment from Lake Singkarak. Bilih fish and sediment samples were taken in June 2021 at ten (10) sampling sites in Lake Singkarak. The samples were extracted and analyzed by gas chromatography. Seven organochlorine compounds were measured, including aldrin, endrin, dieldrin, DDT, heptachlor, lindan, and endosulfan. Meanwhile, three compounds chosen from the pyrethroid group, cypermethrin, permethrin, and α-cypermethrin, were also measured. Four organochlorine compounds, aldrin, dieldrin, DDT, and endrin, were detected in bilih fish in three different sites. Dieldrin had the highest concentration at nd-0.007 mg/kg, followed by DDT, endrin, and aldrin. Meanwhile, in the sediments, no organochlorine compounds were detected from all observed sites. Pyrethroid compounds were detected in bilih fish at six sites. The compound with the highest concentration was permethrin (nd-0.02 mg/kg), followed by cypermethrin and α-cypermethrin. The surface sediment from three sites contained two pyrethroid residues, permethrin and α-cypermethrin, at nd-0.002 and nd-0.001 mg/kg, respectively. Our findings show that the residual levels of organochlorine and pyrethroid in bilih fish still meet the standards set by the Codex Alimentarius Commission (CAC). Nevertheless, Bilih fish accumulate more pesticide than surface sediment, so it is essential to be aware of their potential accumulation in the human body as the final consumer. Restriction on synthetic pesticide application is necessary to reduce its residue input into the lake waters for ecological and human health.

Abstract

The Indonesian tofu industry is dominated by small scale industries with limited capital, so most do not have waste treatment facilities. Waste from the tofu industry in the form of liquid waste has a high BOD and COD content, and exceeds the quality standards set by PerMenLHK No. P.21 of 2018. Treatment of liquid waste from the tofu industry is necessary to reduce BOD and COD concentrations. Phytoremediation is an effective, efficient and environmentally friendly liquid waste treatment method to reduce BOD and COD parameters. This research aimed to determine the effectiveness of Azolla microphylla and Eichhornia crassipes in reducing BOD and COD of tofu liquid waste. The research data consists of BOD and COD test results following the phytoremediation method with a contact time of 15 days. Initial testing of tofu liquid waste showed BOD and COD results of 193.5 mg/L and 489.2 mg/L, respectively. After the tofu liquid waste was treated with the phytoremediation method, the BOD and COD reduction efficiencies were 48.27% and 74.52%, respectively. The effective weight combination for the reduction of BOD and COD parameters is 100 Azolla microphylla + 300 Eichhornia crassipes.
