Abstract

Affandi Street is one of the main Street that uses plant in every road (green line) in an effort to reduce air pollution. Angsana and Glodogan Tiang plants have a role in reducing air pollution. The purpose of this study was (1) to compare the effectiveness of Lead absorption and Carbon Monoxide in the air between Angsana plant and Glodogan Tiang, (2) knowing the point of the highest contamination of the plants and (3) to know the leaf position which has the most effective absorption.The research was conducted on October 2017-February 2018. The method used was the lower and upper leaf sampling on Angsana and Glodogan Tiang at 3 points along Affandi Street that is, the point 1 intersection of Condong Catur, the 2nd point in front of Mirota Gejayan , and point 3 on Demangan market. Repeat sampling three times in one month, then the sample was tested using Atomic Absorption spectrophotometer (AAS) and Spektrofotometer UV-Vis method at Balai Besar Teknik Kesehatan Yogyakarta, and data analysis using ANAVA and MANAVA method with SPSS application. The results showed that plants greatly affect the absorption of air pollutants in the Affandi Street, from the results it is known that the Glodogan Tiang plant is a better plant in absorbing Pb and CO with average absorbing 3.51189 mg/kg, while the average Angsana absorbs 3,38519 mg/kg. The highest point of pollution location is at location point 3, Demangan market. The more effective leaves position in absorbing Pb is the lower leaf plant and the more effective leaf position absorbs the CO that is the upper leaves of the plant.

Abstract

Batik wastewater in the hamlet Mendiro and Sembungan, Village Gulurejo, District LendahKulonProgo Regency is still a problem for batik craftsmen and society. Contamination of well water and river water in the Village Gulurejo due batik effluent, causing adverse health effects and cause a skin disease such asItchingand other skin disorders.The purpose of this IbM program is to increase knowledge about the technology and batik effluent treatment procedures batik so that the quality of effluent discharged to the environment according to the Liquid Waste Quality Batik is valid and does not pollute the environment. To achieve these objectives there should be a batik wastewater treatment equipment that is easy in operation and can be used interchangeably by batik craftsmen. Achieved results or findings is the realization of sewage treatment plants in the form of batik assemblies elektrokoagulan engineering technology with a method that is effective, efficient, easy in operation and requires a power source of120 watts. Wastewater treatment plant that includes batik: batik waste tank capacity of 500 liters; elektrokoagulan tub capacity of 100 liters; 2 bath deposition capacity of 4,000 liters; 3 bath filtration capacity of 6000 liters which includes coral filter media, split and sand & activatedcharcoal.

Abstract

This research is to know the effectivities of household processing biological with active mud pushed by acclimated artificial sewage, it is done by observing parameter DO (Disolved Oxygen), BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), SS (Suspended Solid) and plankton as proponent data and then it is compared with quality standard included on SK Gubernur DIY No.281/KPTS/1998 about liquid waste. Household which is used for researching is from installation unit of waste water Sewon-Bantul. Waste is treatment with active mud pushed by acclimated artificial sewage concentration 0 % (control), 15 %, 30 %, 45 % with time of observation 0 hour, 2 hours, 4 hours, 6 hours, 24 hours. To know concentration of active mud to improve waste quality, it is used SPSS that is anava and Tukey test. The result of this research has shown that processing of household with active mud pushed by acclimated artificial sewage concentration 30 % is the most optimal and it can be improved: DO (63,64 %), BOD (74,06 %), COD (71,96 %), SS (65,57 %), where as the number of identified plankton is 24. The result of waste processing has been also suitable with quality standard of liquid waste included on SK Gubernur DIY No.281/KPTS/1998

Abstract

Transportasi sampah bertujuan membawa sampah dari lokasi pemindahan atau dari sumber sampah secara langsung menuju Tempat Pembuangan Akhir (TPA). Penelitian ini bertujuan untuk 1)mengetahui sebaran Tempat Pembuangan Sementara (TPS) pada 5Kecamatan yang terdapat di Kabupaten Karawang, 2)mengetahui jalur eksisting pengangkutan sampah di Kabupaten Karawang dengan bantuan Sistem Informasi Geografis (SIG), 3)menganalisis dan mengevaluasi efektivitas dan efisiensi rute pengangkutan sampah yang ada saat ini di Kabupaten Karawang dan 4)menghitung tingkat kebutuhan kendaraan pengangkutan sampah yang dibutuhkan di Kabupaten Karawang. Penelitian dilaksanakan di Kecamatan Karawang Barat, Karawang Timur, Telukjambe Barat, Telukjambe Timur dan Klari di Kabupaten Karawang pada bulan Januari – Februari 2020. Untuk melakukan optimasi pola pengumpulan dan pengangkutan sampah menggunakan Sistem Informasi Geografis (SIG) dengan metode Network Analyst. Metode ini menentukan rute yang optimal sehingga dapat efektif dan efisien dalam sistem pengangkutan sampah. Data yang digunakan adalah lokasi poll, TPS dan TPA, jumlah TPS, waktu dan jarak perjalanan yang ditempuh, rute angkutan eksisting, jarak antara pool dengan TPS-TPS dan jarak antara TPS-TPA, jumlah kendaraan. Garbage transportation vehicles needed as many as 128 units which means that additional vehicles need as many as 90 units. Hasil penelitian pada 5 Kecamatan di Kabupaten Karawang kendaraan pengangkutansampah yang beroperasi sebanyak 38 unit dan 111 TPS. Jalur eksisting pengangkutan sampah, rata-rata jaraknya 91,08 km dan waktu tempuh 3,63 jam sedangkan jalur pengangkutan sampah yang sudah dianalisis didapatkan jarak rata-rata 43,94 km dan waktu tempuh 2,32 jam. Jadi mempunyai selisih jarak 53,94 km dan waktu tempuh 1,31 jam pada 38 pengangkutan sampah. Estimasi timbulan sampah yang dihasilkan 1.532,234 m3/hari. Pada saat ini jumlah kendaraan yang terdapat di pool sebanyak 38 unit. Kendaraan pengangkutan sampah yang dibutuhkan sebanyak 128 unit yang artinya perlu tambahan kendaraan sebanyak 90 unit. Biayakonsumsi bahan bakar kendaraan pada rute eksisting sebesar Rp. 4.133.735 per hari sedangkan sesudah dilakukan analisis menjadi Rp. 2.633.879 per hari, jadi penurunan sebanyak Rp. 1.479.856 per hari berarti bisa menghemat biaya operasional pengangkutansampah.
