Today apartment dwellers generally tend to be individualistic righteously urban middleclass society in general. Unlike the situation in the neighborhood, where the level of socialization on the surrounding community is still quite high due to the surrounding community still likes hanging out with the neighbors, especially in the afternoon. Issues raised here is the lack of socialization that occurs between the residents in the apartment. Garden Living means “life park”. Garden is a garden that is as a place of socialization for residents and surrounding communities. Garden Living itself is to make the park as a place to socialize and interact with fellow residents of the apartment and the garden is also a gathering place for the general public. Lack of facilities to accommodate the occupants to socialize the reason the construction of an apartment that has an garden and is expected to become a place to socialize for the residents of the apartment. For the people who live around the apartment also will be built a public park so that people can still socialize and gather together. Taking the concept of Green Architecture or Sustainable Architecture, the building is minimal in consumption of natural resources, including energy, water, materials, and minimal negative impact on the environment. By the way of utilizing rain water and Deli river water and uses sunlight as a power source. 100406064

Bioethanol is one type of biofuel that developed significantly. The utilization of bioethanol is not only limited for fuel, but also could be used as material for various industries such as pharmaceuticals, cosmetics, and food. With wide utilization and relatively simple production technology has made bioethanol as the most favored biofuel currently. The use of lignocellulosic biomass, microalgae, seaweeds, even GMO (Genetically modified organisms) as substrates for bioethanol production has been widely tested. Differences in the materials eventually led to change in the production technology used. Pretreatment technology in the bioethanol production using lignocellulosic currently experiencing rapid development. It is a key process and crucial for the whole next steps. Based on the advantages and disadvantages from all methods, steam explotion and liquid hot water methods are the most promising pretreatment technology available.

Terjadinya Perubahan iklim pada saat ini telah mengkibatkan dampak buruk terhadap kehidupan makhluk hidup di permukaan bumi. Kekeringan, banjir atau rob, gelombang udara panas, dan badai merupakan beberapa contoh yang disebabkan oleh Perubahan iklim. Pada sektor pertanian, kondisi tersebut akan menyebabkan produksi tanaman mengalami penurunan yang cukup signifikan sehingga mengganggu ketahanan pangan nasional dan menurunkan pendapatan petani dan devisa negara. Penyebab utama terjadinya Perubahan iklim adalah meningkatnya emisi gas rumah kaca (terutama gas CO2) di udara, yang dihasilkan oleh aktivitas manusia (antropogenik). Untuk mengurangi emisi gas CO2 Pemerintah Republik Indonesia telah mencanangkan Rencana Aksi Nasional Penurunan Emisi Gas Rumah Kaca (RAN-GRK) sesuai Peraturan Presiden Nomor 61 tahun 2011. Salah satu kegiatan utamanya adalah penanaman 105.200 ha tanaman karet. Peran ekologis tanaman karet yaitu tajuknya dapat menyerap gas CO2 dari udara dan dari hasil biji karet dapat dibuat biodiesel dengan gas buang CO2 yang lebih rendah dari bahan bakar minyak (solar), sehingga tanaman karet mempunyai peran yang penting dalam mengurangi kejadian Perubahan iklim (mitigasi). Jumlah CO2 yang diserap oleh tanaman karet bervariasi tergantung kepada umur tanaman, kondisi tanaman, kesuburan tanah, dan teknis budidaya yang diterapkan. Rata-rata stok karbon pada karet tradional (perkebunan rakyat) 19,8 ton C/ha, sedangkan pada karet klon unggul (perkebunan besar) 42,4 ton C/ha. Jumlah gas CO2 yang diserap oleh perkebunan karet di Indonesia mencapai 291,16 Mton CO2e. Potensi produksi biodiesel dari RSO di Indonesia mencapai 424.460 ton. Campuran solar dan biodiesel dari RSO dapat menurunkan emisi gas buang CO2 sebesar 40,14%. Role of rubber plant in climate change mitigation Climate change happened and resulted in adverse effect of our life on the earth's surface. Droughts, floods, or rob, heatwaves, and hurricanes happened recently of incident that might be caused by climate change. In the agricultural sector, these conditions will lead to reduction of yields significantly, in turn disrupt the national food security and reduce foreign exchange. Major factor that may induce climate change is the increased greenhouse gas emissions primarily CO2 in air, generated by human activity (anthropogenic). To reduce emissions of CO2 gas, Government of Indonesia has launched the National Action Plan for Reducing Emissions of Greenhouse Gases (RAN-GRK) through Presidential Decree No. 61 of 2011. One of the main activity is the planting of 105,200 ha of rubber trees. Ecological role of the rubber plant is an sequestration CO2 from the air. Moreover, rubber yielded may be converted into biodiesel fuel having CO2 content being lower than diesel oil in otherwords, rubber plant has an important role in reducing of incidences of climate change (mitigation). The amount of CO2 is sequestrated by rubber plant varies depending on the age of the plant, crop conditions, soil fertility and technical cultivation applied. Average of carbon stock of those rubber plants cultivated traditionally was 19.8 ton C / ha, while those superior clone ones was 42.4 ton C/ha. The amount of CO2 gas sequestrated by rubber in Indonesia reached of 291.16 Mton CO2e. Potentially biodiesel production developed from the RSO in Indonesia reached 424,460 ton, blending of diesel oil and biodiesel from RSO able to reduce CO2 emissions of 40.14%.

Area of Indonesia consists of 80% water, which contains abundance of potential fish resources, Those fish resources should be utilized for as much as prosperity and welfare for Indonesian. In fact, fish resourceshaven't enhanced the living standard, which is sustainable and equitable. Issues on fisheries come up such as exaggeration of fishing, theft fish, illegal fishing activities and the use of fish resources that exceeding thegeneration of fish itself. That circumstance will cause harm for the state, the fishermen, as well as people in general. The use of tools that harm the nature will cause the decrease of fish resources and threat thesustainability of fish resources. The aim of writing this article is to analyze law enforcement related to the sustainability of fish resources and the sustainability of fish resources, viewed from the perspective of justice.As the result of the study, law enforcement to protect the fish resources generally has not given attention to the sustainability of fish resources, therefore fishermen still use unfriendly tools to catch the fishes. Thoseunfriendly tools will cause the occurrence of over-fishing and will impact to the environmental damages. Those kinds of things will destruct the fishes, therefore the quantity of fish will have deteriorated and evencould be extinct. Those environmental damages would suffer the present generation as well as the next generation since they couldn't consume fish which is very essential for the growth of the human body anderadicate the job for the people as the fishermen. The present generation will be sinful if the next generation will get the impact of what the present generation done. In order to reduce more over-fishing activities and the distrust of the fish habitat it needs the law enforcement, which is oriented to the sustainability of fish resources. The sustainability of fishery resources couldn't maintain its existence, this could be seen as the symbol of environmental damages. In this case, the law also needs to make integration of fish resources sustainability to be processed so that it will result output law enforcement which is oriented to fish resourcessustainability. As a conclusion, in law enforcement oriented to fish resources sustainability, it needs to be thought by the lawmaker to embed that the law should contain idea or concept about justice, legal certainty,the significance of fish resources and the implementation of the law itself. In the fish resources utilization and law enforcements, it needs to pay attention to the justice principle; intergenerational equity; intergenerational equity; precautionary; conservation of biological diversity; conservation of biological diversity.
