Abstrak: Mendirikan rumah akan mengemisikan CO2 ke udara. Emisi CO2 tersebut berasal dari pembuatan dan pengangkutan bahan bangunan, serta pekerjaan konstruksi. Penelitian ini mencoba memperkirakan besaran emisi CO2 dari pembangunan rumah sederhana. Penelitian diawali dengan pendataan jenis bahan bangunan dan perhitungan kebutuhan bahan bangunan setiap tipe rumah yang merupakan fungsi luas lantai. Kemudian penentuan faktor emisi berbagai bahan bangunan didasarkan pada penelitian terdahulu. Untuk memperoleh gambaran hubungan antara jenis bahan bangunan dan tipe rumah dengan besaran emisi CO2, simulasi dilakukan dengan berbagai skenario yang menyertakan luas rumah dan variasi bahan bangunan sebagai variabel. Hasil simulasi menunjukkan bahwa tipe rumah dan jenis bahan bangunan berperan penting dalam mencapai besaran emisi CO2. Terdapat indikasi bahwa kerumitan pembuatan bahan bangunan dan rumah mempengaruhi besaran emisi CO2. Dengan demikian kesimpulan yang dapat diambil adalah besaran emisi CO2 berbanding lurus dengan luas rumah, jenis dan volume kebutuhan bahan bangunan serta tingkat kerumitan proses konstruksi. Dengan mempertimbangkan variabel tersebut, konstruksi suatu rumah yang rendah emisi CO2 dapat direncanakan.Kata kunci: emisi, CO2, bahan bangunan, rumah Abstract : Construction of a house will emit CO2 into the air. The emitted CO2 comes from manufacturing and transporting building materials and construction works. The study tried to estimate the amount of CO2 emissions from the construction of low-cost houses. The study begins with data collection on the type of building materials and the estimation of the required volume of the building materials for each type of house that is a function of floor area. Then the emission factors of various building materials are determined based on several previous researches. To obtain a figure of the relationships between the type of building materials, type of house with the amount of CO2 emissions, simulations were carried out with the wide variety of scenarios that include house type and variety of building materials as variables. The simulation results show the relationship between the type of the house and the type of building materials plays important roles in the amount of CO2 emision. There are indications that the complexity of manufacturing a building material and the house affect the emissions of CO2. Thus the conclusion is that the amount of CO2 emission is proportional to the area of the house, types of building materials and the volume of building material needs, and the complexity of the construction process. Taking into account of these variables, construction of a houseemitted low CO2 can be planned. Key words: CO2, emissions, construction materials, house.

Abstrak: Kegiatan keramba jaring apung yang dikembangkan di Waduk Jatiluhur berfungsi untuk memenuhi kebutuhan pangan. Namun, akibat pertumbuhannya yang cepat dan tidak terkendali maka kegiatan keramba jaring apung telah menjadi sumber pencemar utama, termasuk nitrat, dalam Waduk Jatiluhur. Nitrat sebagai salah satu nutrien yang dapat digunakan langsung oleh biota air merupakan salah satu pemicu terjadinya eutrofikasi dalam waduk. Degradasi kualitas air akibat eutrofikasi dapat mengganggu fungsi waduk sebagai pembangkit listrik dan penyedia pasokan air baku air minum serta irigasi pertanian. Upaya yang dapat dilakukan untuk mengatasi hal tersebut adalah dengan merelokasi keramba jaring apung dari daerah disekitar outlet waduk menuju lokasi yang lebih jauh dari outlet waduk. Untuk melihat sejauh mana pengaruh kegiatan keramba jaring apung dalam waduk maka dilakukan simulasi konsentrasi nitrat dalam air waduk dengan menggunakan pendekatan segmentasi vertikal. Simulasi konsentrasi nitrat juga dilakukan dengan menerapkan skenario perbaikan berupa relokasi keramba jaring apung. Simulasi terhadap skenario perbaikan dilakukan sebagai suatu langkah optimasi dalam rangka mereduksi konsentrasi nitrat di outlet waduk. Hasil simulasi menunjukkan bahwa upaya pengelolaan dengan merelokasikan keramba jaring apung menuju lokasi yang lebih jauh dari outlet wasuk telah berhasil menurunkan konsentrasi nitrat di segmen terakhir waduk. Dari hasil simulasi didapat bahwa reduksi konsentrasi nitrat tertinggi didapatkan dengan cara merelokasi keramba jaring apung dari segmen kedelapan menuju segmen kedua. Dengan merelokasikan keramba jaring apung menuju segmen kedua sebanyak 20%, 50%, dan 100% dari jumlah keramba jaring apung di segmen kedelapan masing-masing telah berhasil menurunkan konsentrasi nitrat sebesar 16,67%, 41,52%, dan 82,37% pada segmen terakhir waduk. Kata kunci: keramba jaring apung, nitrat, Waduk Jatiluhur, kualitas air. Abstract: Fish cagesin Jatiluhur reservoir are developed in order to meet the food demands. However, due to its rapid and uncontrollable growth, fish cages turn to be the major pollutant source in Jatiluhur reservoir. Nitrate, as one of nutrient that can be use directly by aquatic biota, is one of the factor that trigger eutrophication in a reservoir. Water quality degradation caused by eutrophication can hinder reservoir function as a hydro-electric generation and water resources that provided raw water for drinking water and irrigation. An effort that is possibly done to overcome the problem was by relocating the fish cages to upstream site. The simulation of nitrate concentration that approached by vertical segmentation then being done to see to what extent fish cage number affected the nitrate concentration in reservoir. The simulation was also being done by implementing improved scenario. The simulation with improved scenario carried out as an optimization measure in order to reduce the nitrate concentration in reservoir outlet. The results of the simulation indicated that by relocated the fish cage to further location from reservoir outlet has been successful reduce nitrate concentration in the last segment of the reservoir. The highest nitrate concentration reduction was obtained when the fish cage was relocated from the eighth segment to the second segment of the reservoir. By relocate the fish cage as much as 20%, 50%, and 100% of the number of fish cage in the eighth segment the nitrate concentration reduction in the last segment is 16.67%, 41.52%, and 82.37% respectively.

Increases in coastal pollutants, largely due to human activity on land, have an impact on seagrass ecosystems. The high sedimentation in the waters causes an increase in the concentration of sludge, organic matter, nutrients, and turbidity which reduce the depth that can be reached by sunlight. The condition affects seagrass ecosystems adversely. Changes in water condition can be illustrated by the presence of water organisms. One dominant organism in seagrass ecosystems is periphyton. The existence of periphyton in the waters is determined by physical and chemical conditions of the waters because it has specific limit of tolerance, which causes different community structure. To analyze periphyton response to the changes of environmental quality in seagrass ecosystems, Shannon Winner diversity and Saprobic Indices were measured at Panjang Island, Banten. The results of water quality assessment indicates the status of aquatic seagrass of the island considered as polluted to heavy polluted. It is observed from some physico-chemical parameters that exceeded the standard quality for the life of seagrass ecosystems and marine life. Based on the classification and saprobic coefficient using periphyton biological parameters, the condition of seagrass land ecosystem in the island is classified into β Mesosaprobic to β/α Mesosaprobic phase, which indicates light to medium pollution with pollutants including organic and inorganic materials. Several types of dominant periphyton were discovered during the observations, including Meridion sp, Navicula sp, Nitzschia sp and Synedra sp. This periphyton species belong to Bacillariophyceae class (Family Chrysophyta) that is commonly used to assess the condition of eutrophication and organic pollution on waters.

Computer model is developed to relate parameters that determine the performance of a contact-stabilization system. Based on mass and substrate balance in the system, relationships between the variables are developed, then simulations using various values of the parameters can produce trend lines indicating the behavior of a system as well as the required conditions to reach an expected performance. When the operating conditions, such as recycled sludge and wasted sludge are changed, the model demonstrates alterations of the performance consistent to the developed mathematical relationships. Additionally, the computer model shows that the results could produce further explanation on phenomena of biological processes in contact-stabilization systems.
