Judul: Laju Penyerapan Emisi CO2 Berdasarkan Nilai Fluks Karbon pada Ruang Terbuka Hijau (Studi Kasus : Kampus IPB Darmaga Bogor).
Abstrak: Kampus Institut Pertanian Bogor (IPB) Darmaga sebagai pusat administrasi dan perkuliahan memiliki tingkat aktivitas serta mobilitas yang tinggi. Beberapa aktivitas kampus yang menjadi sumber emisi karbondioksida (CO2) ialah aktivitas konsumsi energi listrik, transportasi, pernapasan, dan peternakan. Luasan ruang terbuka hijau (RTH) tersedia yang mencapai dua pertiga bagian, seharusnya memiliki laju penyerapan CO2 yang tinggi pula. Berdasarkan hal tersebut, penelitian ini bertujuan untuk menghitung laju emisi CO2, menghitung laju penyerapan CO2 melalui pendugaan Net Primary Productivity (NPP) serta menentukan penambahan luasan RTH yang dibutuhkan di wilayah sekitar kampus. Hasil penelitian menunjukkan bahwa laju emisi CO2 di sekitar kampus IPB Darmaga mencapai 18 969.2 ton/tahun, dimana 5147.9 ton berasal dari emisi langsung CO2, sedangkan 13 821.2 ton berasal dari emisi tak langsung CO2. Adapun laju penyerapan CO2 oleh RTH kampus mampu mencapai 18 309.1 ton/tahun. Laju penyerapan CO2 yang lebih rendah dibandingkan laju emisi CO2 menyebabkan adanya sisa emisi sebesar 642.3 ton, sehingga dibutuhkan penambahan luasan RTH sebesar 1.1 ha.

Abstrak: The increase of temperature in urban area is indirectly caused by the increase of Carbon Dioxide (CO2) concentration in the atmosphere. The increase is caused by land cover alteration and high amount of human activities which uses fossil fuel. The existence of urban forest is one of the ways to coupe the increase of CO2 concentration in the urban atmosphere. Through photosynthesis process, CO2 gas is absorbed by various plants in urban forest and afterwards being released as Oxygen (O2). To control or reduce the concentration of CO2 effectively, in the establishment of urban forest, selection of plants which have maximum ability in reducing CO2 concentration needs to be done. The objectives of this research are to obtain data CO2 sink ability of 15 urban forest plant species in Bogor Agricultural University and to obtain data about the plant species that has the effective CO2 sink ability among the plants which are measured. The measuring of CO2 sink ability was conducted using carbohydrate method. CO2 mass is obtained by converting carbohydrate mass produced in photosynthesis. Other data taken include leaf area and the number of leaves. The higher the leaf area, the higher CO2 sink ability of a leaf. The higher number leaf of a tree, the higher CO2 sink in a tree. The CO2 sink ability of 15 plant species in cm2 of leaf area are (g CO2/cm2/hour): M. caesia 3,793 x 10-4; D. indica 2,180 x 10-4; B. racemosa 1,600 x 10-4; S. campanulata 1,249 x 10-4; M. champaca 1,176 x 10-4; S. malacense 0,820 x 10-4 ; B. capitella 0,805 x 10-4; C. cauliflora 0,734 x 10-4; V. pubescens 0,669 x 10-4; C. inophyllum 0,629 x 10-4 ; M. ferrea 0,479 x 10-4; A. moluccana 0,357 x 10-4; A. dammara 0,268 x 10-4-; and G. dulcis 0,089 x 10-4. The CO2 sink ability of 15 plant species in urban forest in order from the highest are D. indica, M. caesia, S. campanulata, C. inophyllum, B. racemosa, V. pubescens, M. ferrea, C. cauliflora,B. capitella, G. dulcis, M. champaca, S. malacense, A. moluccana, and A. dammara.

Abstrak: Short Message Service (SMS) is a method of text-based communication commonly used by many mobile phone users of its cost and flexibility. Unfortunately, text-based communications require those with good eyesight, leaving behind those with visual impairment, especially low vision people. A number of devices were built exclusively for blind and low vision people to communicate with ease, but cost is often a major drawback. This study developed a mobile application that helps the visually impaired to use the SMS feature on Android uses Waterfall method. This study resulted in an application that allows low vision users in using SMS feature on Android.
