Abstract

Environmental Management effort in conservation will be required to diverse natural resources value, and as a form of favouring the sustainability of biological natural resources and its ecosystem utilization in City Forest of Telagasari (HKTs). HKTs have been designated as a green open space and it is developed as a protected area and education center of biodiversity in Balikpapan City. Data collection was done by direct observation method on terrestrial fauna and flora. There are 133 kind of flora in HKTs (11 flora are protected by IUCN and 14 flora are  protected by PP RI in SK/54/Pertanian/1972) with a Shannon-Wiener Index (H’) 3.04 for ‘semai’ category, 3.02 for ‘pancang’, 3.02 for ‘tiang’, and 1.86 for ‘pohon’ category. The numbers of avifauna that had been recorded in city forest of Telagasari are 35 species (7 has important protection status), with a Shannon-Wiener Index (H’) of 2.762. The numbers of mammals that had been recorded in city forest of Telagasari are 7 species and 21 individuals, with H’ mammals of 1.5. This inventory data and information can be used to support the conservation, as an environmental management effort. The baseline of biodiversity and conservation status in HKTs Balikpapan will be measured as a key parameter for the implementation of biodiversity protection program. The strategic planning and program that are proposed for next fifth year for HKTs may give a positif impact for biodiversity and conservation in HKTs.

Abstract

Model transfer massa dalam reaktor absorpsi semi batch untuk mengolah CO2 menggunakan limbah las karbid telah dikembangkan berdasarkan hukum kesetimbangan massa, teori transfer massa dan laju reaksi. Simulasi model reaktor dilakukan dengan solver ODE45 program MATLAB R2009a dengan pendekatan Metode Runge-Kutta orde 4. Asumsi yang digunakan dalam pemodelan ini adalah reaktor bekerja pada kondisi steady state, kedua fasa berada pada suhu 25°C, kecepatan pengadukan serta bubbler diabaikan, dan orde reaksi merupakan pseudo orde satu. Model divalidasi dengan menggunakan hasil penelitian laboratorium absorpsi CO2 oleh limbah las karbid dalam reaktor semi batch dengan konsentrasi inlet sebesar 18%. Absorpsi CO2 oleh limbah las karbid yang mengandung Ca(OH)2 terutama terjadi pada liquid-bulk sehingga perpindahan massa akan terjadi lebih besar di liquid-bulk dibanding dengan perpindahan massa di gas-liquid film. Model matematis yang dikembangkan dengan solusi numerik menggunakan metode Runge Kutta orde 4 secara umum dapat menggambarkan pola yang hampir sama dengan hasil penelitian laboratoirum, walaupun digunakan nilai konstanta reaksi hasil penelitian yang jauh lebih lambat daripada nilai konstanta reaksi teoritis.

Abstract

The textile industry has the biggest impact on environmental pollution in the world, and is responsible for 10% of global carbon production. Most of the waste in the textile industry, is generated from the dyeing process and textile processing. PT X is a textile finishing industry, that focuses on finishing processes like dyeing and textile processing. In this research, GHG (greenhouse gasses) emission inventory was carried out to see how much GHG generated in the textile finishing industry. The inventory will focus on CO2, CH4, and N2O from generator, curing machine, operational vehicle, and electricity usage. The inventory methodology was based on IPCC 2006, that stated to determine GHG emission, an activity data and emission factor from that source is needed. This emission inventory results on the total emissions of 666.38 tonCO2eq or 258.629 kgCO2eq/tonproduct GHG emission from PT X in 2021. The GHG emission in PT X are dominated by CO2 gas. Which most of comes from electricity usage source. GHG emission produce by PT X are not high compared with similar industries, but can be improved further more with mitigation measures such as installing a solar panel, and constructed wetland.
