Abstract

Pembangunan Ruas Jalan Lintas GeumpangPameu merupakan bagian dari program strategis nasional untuk meningkatkan konektivitas wilayah di Provinsi Aceh. Namun, kegiatan konstruksi seperti ini berpotensi menimbulkan dampak negatif terhadap lingkungan, khususnya kualitas udara, air, vibrasi, dan kebisingan. Oleh karena itu, dilakukan pemantauan kualitas lingkungan untuk memastikan pembangunan tetap sejalan dengan prinsip keberlanjutan. Pemantauan dilakukan pada tiga titik lokasi dengan parameter utama meliputi kualitas udara ambien, kualitas air, vibrasi lingkungan, dan kebisingan. Hasil pemantauan menunjukkan bahwa kualitas udara ambien masih berada di bawah baku mutu yang ditetapkan. Kebisingan dan vibrasi yang dihasilkan tergolong rendah dan tidak melebihi ambang batas yang dapat menyebabkan gangguan kesehatan. Sementara itu, kualitas air sebagian besar masih dalam batas aman, meskipun beberapa parameter seperti BOD, COD, dan logam berat menunjukkan nilai yang melebihi ambang baku mutu. Namun demikian, hasil analisis menyimpulkan bahwa peningkatan kadar tersebut lebih dipengaruhi oleh faktor lingkungan alami daripada aktivitas konstruksi. Pemantauan ini menjadi dasar penting dalam upaya pengelolaan dan pengendalian dampak lingkungan, serta dapat dijadikan rujukan bagi kegiatan serupa di masa mendatang.

Abstract

Desa Teuladan dikenal sebagai salah satu desa penghasil pepaya terkemuka di Kabupaten Aceh Besar, Provinsi Aceh. Pepaya banyak dibudidayakan di kebun dan di sekitar tempat tinggal penduduk desa, dengan sekitar 90% rumah tangga terlibat dalam budidaya tanaman pepaya ini. Meskipun demikian, petani pepaya menghadapi tantangan yang signifikan terkait dengan volatilitas harga. Harga pepaya sangat dipengaruhi oleh faktor-faktor seperti kondisi cuaca, frekuensi panen, dan ketersediaan pembeli. Biasanya, harga pepaya mengalami peningkatan selama bulan-bulan musim panas, sementara harganya cenderung menurun tajam selama musim hujan. Untuk meningkatkan nilai pasar pepaya pascapanen, diversifikasi produksi menjadi saus pepaya merupakan strategi yang tepat. Metodologi yang digunakan dalam inisiatif pengabdian masyarakat ini mencakup survei terhadap tantangan yang dihadapi oleh kelompok sasaran petani pepaya, diikuti dengan pendekatan terhadap permasalahan yang dihadapi kelompok tani pepaya sasaran, dilanjutkan dengan penyuluhan serta pelatihan dan praktek langsung pembuatan saus pepaya. Materi pelatihan tidak hanya difokuskan pada cara pembuatan saus pepaya, akan tetapi juga mencakup materi tentang keuangan dan pemasaran. Keberlanjutan suatu usaha akan sangat tergantung kepada pemasaran yang dijalankan. Kegiatan pengabdian dengan melakukan penyuluhan dan pelatihan tentang pembuatan saus pepaya berhasil dengan baik. Hal ini terlihat dari peran peserta yang sangat aktif dan sungguh-sungguh pada waktu mengikuti pelatihan ini. Kegiatan ini juga menciptakan suatu kegiatan kewirausahaan bagi kelompok tani pepaya desa tanpa membutuhkan modal yang banyak sehingga dapat menambah pendapatan keluarga.

Abstract

AbstractStudy of reducing the content of ammonia, carbon dioxide and organic contaminants in wastewater process condensate using a combination of technologies of water Jet Stripping Bubble Colum, Advance Oxidation Process and Ion Exchange Resin have been done. The aims of this research is to look the effect of hydraulic resident time in Jet Stripping Bubble Colum and the amount of the addition of Ozon/H2O2 to reduction the content of carbon dioxide and organic contaminants as well as ammonia removal with ion exchange resin on the process condensate so that can be reuse as boiler feed water in ammonia plant of PT. PIM. This research was conducted using a combination Air Stripping Jet Bubble Colum, Advance Oxidation Process and Ion Exchange Resin which equipped with water and air flows adjustment. The water flow enter the column, pressure of the Colum and diameter of nozzle was maintained constantnts during experiment, while the air flow rate enter to the column, H2O2/O3 concentrations and the hydraulic retention time was vary respectively. The results showed that the water Jet Stripping Bubble Colum at 50 Psi air pressure capable of achieving CO2 lowers 87.60% and ammonia to 65.31%. AOP technology capable of lowering the content of organic contaminant to 80.71% with the addition of hydrogen peroxide 8,000 ppm with a residence time 180 minutes. While the ammonia remaining in the water the process of condensate action exchange resin using eliminated with a reduction of ammonia reached 98.57%, so that the recovery process of water condensate technology uses a combination of Air Stripping Jet Bubble Colum, Advance Hydrocarbon processes (AOP) and Ion Exchange Resins already meets the requirements of viable reuses boiler feed water. The ammonia reduction was determined by using ASTM-D 1426 method, the carbon dioxide by using ASTM-512 method, and the organic contaminants by using titrimetric method (SII-0071).Keyword : Air Stripping Jet Bubble Colum, Advance Oxidation Process (AOP), Ammonia Removal, Carbon Dioxide Removal.

Abstract

Lead (Pb) and chromium (Cr) are common groundwater contaminants at industrial installation. Zeolites are widely use as an adsorbent in heavy metal removal. Nanocrystalline zeolite Y has been synthesised from a clear solution at 1500C by using aluminum isopropoxide (Al(OiPr)3 and Ludox LS as alumina and silica source, tetramethylammonium hydroxide (TMAOH) and tetramethyl ammonium bromide (TMABr) as first and second organic template, respectively. The products were characterised by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) to identify the structure and particle sizes. After 48 hours synthesis time, nanocrystalline zeolite Y samples were obtained with approximately average particle sizes of 268 and 119 nm for one and two organic templates, respectively. The synthesized nanocrystalline zeolite Y was applied for some metal adsorption including Pb(II) and Cr(III) and the results show that the nano crystal samples have good performance. The removal efficiency for Pb and Cr could be up to 88.97% depending on the initial concentration and temperature. The adsorption isotherms of Cr and Pb were determined from the Langmuir and Freundlich equations. The equilibrium sorption capacities (Qe) from the Langmuir equation were 270.27 mg/g and 204.08 mg/g at 300C for Pb and Cr, respectively. Kinetic adsorption analysis of nanozeolite Y shows that the pseudo second order kinetics would be better for fitting the dynamic adsorption of both Cr and Pb cations.Key words: adsorption isotherms, kinetic adsorption analysis, nanocrystalline zeolite Y

Abstract

Water quality assessment in the tsunami-affected areas conducted in Meuraxa and Kutaradja sub-districts in the area of Banda Aceh City. Water samples were collected in October 2006 from dug wells of tsunami-affected areas. These were characterized for various physical and chemical parameters. Water quality in the selected areas has shown that the surface water was contaminated due to the tsunami. Total Dissolved Solid, Total Suspended Solid, Acidity, and salinity were high in the affected areas indicating saline water intrusion into surface water tables. Dug wells in the highly affected locations showed higher values of heavy metal ions like Mn, Pb, Cu, Fe, Zn, and Cu compared to the reference points. No ion Hg was found in all samples. Keywords: Banda Aceh, heavy metals, tsunami, water quality
