Estimasi Valuasi Serapan Karbon Pada Tanaman Perdu dengan Metode Nowak di Hutan Kota Srengseng Jakarta Barat = Estimation of Carbon Uptake Valuation on Shrubs Using The Nowak Method In Srengseng City Forest, West Jakarta
"Peningkatan pertumbuhan penduduk di DKI Jakarta memicu tingginya pembentukan gas emisi karbon dioksida yang berdampak pada perubahan iklim global. Keberadaan Ruang Terbuka Hijau dalam bentuk hutan kota menjadi salah satu solusi pemerintah sebagai upaya menstabilkan iklim mikro di perkotaan. Tanaman perdu menjadi salah satu komponen vegetasi di hutan kota. Selain perannya sebagai tanaman hias, tanaman perdu memiliki fungsi ekologis yang kerap kali diabaikan. Penelitian ini dilakukan guna mengetahui estimasi daya serap serta simpanan karbon pada tanaman perdu di Hutan Kota Srengseng Jakarta Barat dengan menggunakan metode Nowak. Metode Nowak merupakan metode non destruktif yang diinisiasi oleh United States Department of Agriculture dengan melakukan pengukuran diameter batang tanaman perdu. Berdasarkan hasil penilitian didapatkan estimasi daya serap karbon pada vegetasi perdu di Hutan Kota Srengseng memiliki nilai serapan karbon sebesar 0,07 ton/thn atau setara dengan 6.350 kg/thn serta simpanan karbon sebesar 0,24 ton atau setara dengan 21.772 kg. Daya simpan serta daya serap karbon terbesar diperoleh tanaman Murbei. Perencanaan penanaman vegetasi perdu dari sisi fungsi ekologis di hutan kota memerlukan peninjauan berdasarkan daya serap karbon.
The increase in population growth in DKI Jakarta triggers the high formation of carbon dioxide emission gas which has an impact on global climate change. The existence of Green Open Spaces in the form of urban forests is one of the government's solutions as an effort to stabilize the microclimate in urban areas. Shrubs are one of the vegetation components in the urban forest. In addition to its role as an ornamental plant, shrubs have an ecological function that is often overlooked. This research was conducted to estimate the absorption capacity and carbon storage of shrubs in the Srengseng City Forest, West Jakarta, using the Nowak method. The Nowak method is a non-destructive method initiated by the United States Department of Agriculture by measuring the stem diameter of shrubs. Based on the research results, it was found that the carbon absorption capacity of shrub vegetation in Srengseng City Forest had a carbon storage value of 0.24 tons = 21.772 kg with a carbon absorption value of 0.07 tons/year 6.350 . The greatest capacity to store and absorb carbon is obtained by Mulberry plants. So, planning for planting shrubs from an ecological function point of view requires a review based on carbon absorption."

Estimasi nilai stok karbon dan serapan emisi karbon pada jalur hijau jalan nasional Kabupaten Karawang menggunakan citra resolusi tinggi = Estimated stock carbon value and carbon emissions sinks on the green belt of national road Karawang using high resolution imagery
"ABSTRAK
Kabupaten Karawang dilewati oleh Jalan Nasional Rute 1 atau yang dikenal
dengan nama Jalur Pantai Utara (Pantura). Jalan nasional ini menghubungkan kota
besar seperti DKI Jakarta dan kota-kota besar di Jawa Barat yaitu, Cirebon dan
Bandung dengan Kabupaten Karawang. Hal ini menjadikan jalan nasional di
Kabupaten Karawang memiliki volume lalu lintas yang tinggi. Dinamika arus
kendaraan pada jalan nasional berbanding lurus dengan jumlah karbon yang
terdapat pada jalan tersebut. Untuk itu penelitian stok karbon penting untuk
mengetahui sejauh mana kontribusi jalur hijau jalan yang berada di sepanjang jalan
nasional ini dalam menyerap gas rumah kaca khususnya CO2. Metode indeks
vegetasi digunakan sebagai metode yang efisien untuk mengestimasi nilai stok
karbon. Indeks vegetasi yang memiliki nilai korelasi paling tinggi dengan sampel
di lapangan adalah EVI, sehingga EVI merupakan indeks vegetasi yang cocok
untuk digunakan pada penelitian ini. Hasilnya estimasi nilai stok karbon jalur hijau
jalan nasional Kabupaten Karawang sebesar 9.046 ton/ha dan daya serap karbonnya
mencapai 33.170 ton/ha. Sementara total rata-rata emisi karbon yang dihasilkan
oleh kendaraan yang melewati jalan nasional tersebut mencapai nilai 65.868 ton per
harinya. Sebagian besar segmen jalan nasional di Kabupaten Karawang mampu
menyerap dengan baik emisi karbon yang dihasilkan oleh kendaraan yang melewati
jalan tersebut.
ABSTRACT
Karawang regency passed by the National Road or Route 1, known as the
North Shore Line (coast). This national road connects major cities such as Jakarta
and major cities in West Java, namely, Cirebon and Bandung with the Karawang
regency. This makes the national road in the Karawang regency has a high traffic
volume. The dynamics of the flow of vehicles on national roads is directly
proportional to the amount of carbon contained in the road. For the study of carbon
stocks is important to know the extent of the contribution of the green belt road that
is along the national road is to absorb greenhouse gases, especially CO2. Vegetation
index method is used as an efficient method to estimate the carbon stock.
Vegetation index that has the highest correlation with the value of the samples in
the field is EVI, so the vegetation index EVI is suitable for use in this study. The
result is the estimated value of stock-carbon green belt national road Karawang
regency of 9.046 tonnes / ha and absorption of carbon reaching 33.170 tonnes / ha.
While the average total carbon emissions produced by vehicles passing through the
national road reaches the value of 65.868 tons per day. Most of the national road
segments in the Karawang regency are able to absorb the carbon emissions
produced by vehicles passing through the road.

"Pemanfaatan kembali material granular alternatif dari limbah agrikultur, konstruksi maupun pembongkaran gedung berbahan beton sebagai pengganti agregat kasar alami merupakan salah satu solusi untuk mengatasi isu lingkungan di industri konstruksi. Penelitian ini bertujuan untuk menilai beton yang paling ramah lingkungan dari tiga beton dengan agregat berbeda, yaitu beton agregat cangkang kelapa sawit, beton agregat alami, dan beton agregat daur ulang, yang diproduksi pada skala laboratorium dalam bentuk balok. Beton tersebut diurutkan berdasarkan dampak lingkungan, konsumsi mineral alami dan timbulan limbah dari produksi masing-masing beton. Penilaian daur hidup (life cycle assessment) dilakukan untuk menganalisis dampak lingkungannya, pengaruh transportasi agregat cangkang kelapa sawit, serta pengaruh alokasi antara produksi beton agregat alami dan produksi agregat daur ulang. Selanjutnya, dilakukan estimasi serapan karbon dioksida selama 25 tahun beton tersebut dipakai dan pengurutan peringkat beton berdasarkan kriteria lingkungan dengan metode VIKOR. Dari analisis tersebut, beton agregat daur ulang dapat dinyatakan sebagai beton paling ramah lingkungan yang memenuhi persyaratan-persyaratan solusi terkompromi.
Reusing granular by-product materials from agricultural, construction and demolition waste of buildings as a substitute for natural coarse aggregate could alleviate environmental issues in the construction industry. This study aimed to determine the greenest concrete among three types of concrete: oil palm shell aggregate concrete, natural aggregate concrete, and recycled aggregate concrete, produced on a laboratory scale in a form of beam. These types of concrete were ranked according to environmental impacts, mineral resource depletion and waste generation from their production. A life cycle assessment (LCA) was conducted to analyse its environmental impacts, the effect of transporting oil palm shell aggregates and the allocation effect between the production of natural aggregate concrete and recycled concrete aggregate. Afterwards, the carbon dioxide uptake of the concretes was estimated for 25 years of use and ranked based on environmental criteria using the VIKOR method. Results have shown that recycled aggregate concrete can be presented as environmentally friendly concrete that meets the compromise solution requirements."
