Abstract

This study aims to map the concentration of carbon monoxide (CO) in Medan city and to estimate the potential reduction in carbon monoxide in some streets of Medan by applying mass transit based on simulation. This research was conducted by sampling CO in the 12 (twelve) points in Medan by grab sampling. CO concentration was analyzed using NDIR methods by CO Monitor tools. The results showed the concentration of CO in Medan between 1145.2 mg/m3 - 27484,7 mg/m3. This condition is still below the national ambient air quality standard of Government Regulation No. 41, 1999 (30,000 mg/m3). Based on the concentration isophlet map that points that have the highest concentration located in the surrounding roadside such as at Jl. SM Raja. To reduction the CO concentration in the ambient air around the roadside is necessary to plan programs and policies related to transportation. If the scenarios or simulation with application of the concept of mass transportation such as BRT CNG and BRT Diesel in some streets of Medan then will be able to reduce CO emissions of about 25.02% to 29.44%.Keywords: vehicle emissions, carbon monoxide, map isophlet, mass transitABSTRAKPenelitian ini bertujuan untuk memetakan konsentrasi gas karbon monoksida (CO) di Kota Medan dan melakukan estimasi potensi penurunan karbon monoksida di beberapa ruas jalan Kota Medan dengan menerapkan transportasi massal berbasis simulasi.

Abstract

As the population increases, waste generation and composition will increase. Therefore, there is a need for planned and effective waste handling so that the problem of waste can be resolved in accordance with the 3R (Reuse, Reduce, and Recycle) concept. The aim of this research is to calculate the amount of waste generation and the composition of domestic waste produced by the residents of Medan Denai, and also devise the type of 3R Waste Treatment Plant for the District of Medan Denai. The method for measuring the generation and composition of waste are based on SNI 19-3964-1994, that is based on income level. Meanwhile, the typical planning of TPS 3R is obtained from the calculation of waste generation which is associated with the projection of population. The result showed that the average of household waste in the District of Medan Denai was 0.265 kg/person/day or 1.4 l/person/day. The composition of household waste generation in the District of Medan Denai is dominated by food waste 65.38 %. It is estimated that in 2026, the waste generation produced in the District of Medan Denai would reach about 41,593.7 kg/day. The economic potential that can be generated by using 3R concept is estimated reaching about Rp11,687,190 - Rp85,370,971 per day. Managing waste with 3R concept require a TPS with 1,488.24 m2 of area to process the household waste, with the estimated cost required to build the facility is Rp598,960,540 and the operational cost is Rp104,000,000 per month.

Abstract

Batang Arau banyak mengalami polusi air, pencemaran air sungainya memberikan kerusakan DAS dan peningkatan sedimen. Ini mengakibatkan banyaknya masuk buangan limbah cair yang bersumber dari limbah penduk dan limbah industri. Batang Arau adalah salah satu sumber air baku terutama sumber air baku untuk kebutuhan sehari dan sekarang kualitasnya sudah sangat menurun. Tinjauan mutu kualitas air sesuai dengan kriteria pada Peraturan Pemerintah No.82 tahun 2001 tentang pengelolaan kualitas air dan pengendaliannya.  Metode yang dipakai dalam pengujian ini metode SNI mengenai parameter kualitas air dan standar methode untuk pemerisaan air dan air limbah, Apha washington DC serta beberapa alat untuk pengujian mutu, data sekunder sebagai pendukung data dan lokasi letak penelitian contoh uji. Tujuan penelitian ini adalah untuk menguji, meneliti dan evaluasi kualitas air di berbagai tempat di Sungai Batang Arau . Kualitas air sangat dipengaruhi pencemaran lingkungan daerah aliran sungai, oleh rumah potong hewan, kegiatan pertanian yang terletak di hulu, serta kegiatan industri karet yang terletak di bagian hilir sungai. Jumlah suspended solid jauh lebih tinggi di aliran sungai menurun. Itu adalah sekitar 144 mg/L di hilir dan hanya 74 mg/L di hulu lokasi. Konduktivitas daya hantar listrik adalah sekitar 114–189 Umhos/cm. The BOD dan COD nilai yang variabel sekitar 3,4-9,7 mg/L. Padatan Terlarut yang terkandung dalam air sungai Batang Arau juga akan mempengaruhi tingkat beban pencemaran dalam air yang dapat menyebabkan penurunan kualitas air sungai Batang Arau, nilai BOD berkisar 5,3 mg/L – 18,3 mg/L dan nilai COD 13,7 mg/L - 50,7 mg/L. Dalam air sungai Batang Arau padatan terlarut hulu bagian 112- 124 mg/L dan di hilir 118 –144 mg/L. DO adalah variabel di  hulu karena air dari berbagai anak sungai berkisar 4,8 – 7,3 mg/L. Kualitas air yang berubah – rubah (tercemar) disebabkan limbah cairan yang masuk ke aliran sungai. Berdasarkan fakta-fakta IPAL pengolahan air limbah tidak beroperasi pada kondisi yang optimal. Operasi rencana pengolahan air limbah yang efektif dan peraturan pembuang limbah cair sebelum lepas ke sungai diharapkan untuk memenuhi standar kualitas air nasional.  Pengolahan limbah cair dengan treatmen fisika, kimia dan biologi menjadikan kualitas air bagus.

Abstract

Electroplating industry is one of the industries producing liquid waste containing heavy metals. Among the heavy metals contained in the liquid waste is Chromium (Cr) which has a high toxicity. One technology that can be applied to eliminate Cr metal in liquid waste is by the method Biosorption using biomass derived from yeast bread (Saccharomyces cerevisiae). This study aimed to study the ability of bread yeast biomass (saccharomyces cerevisiae) in removing Cr metal on variations in biosorbent weight of 0.25; 0.5 and 0.75 grams, mesh size 80; 100 and 140 and contact time 1; 2; 3 and 4 hours. The results showed that the highest Cr removing efficiency occurred at 0.75 g biosorbent weight at 80 mesh and 4 hours contact time with efficiency of 54.7%. The biosorption process indicates that the adsorption isotherm type obtained is Langmuir isotherms assumed that the layer formed is monolayer with R2 value of 0.8819. The SEM analysis results show the difference of the morphological shape on the sample surface before and after the biosorption process
