Analisis daya serap karbon dioksida daun baobab (adansonia digitata l.) dengan konversi massa karbohidrat menggunakan metode nelson somogyi di Kampus Universitas Indonesia, Depok = Analysis of the carbon dioxide absorption capacity of baobab leaves (adansonia digitata l.) with carbohydrate mass conversion using the nelson somogyi method at University of Indonesia Campus, Depok
"Kondisi kualitas udara di Indonesia saat ini sangatlah fluktuatif. Kondisi kualitas udara yang fluktuatif dapat terjadi karena beberapa faktor. Salah satu faktor yang berperan dalam kualitas udara adalah intensitas emisi karbon dioksida di udara. Karbon dioksida yang berlebih dapat menghasilkan emisi gas rumah kaca dan menjadi penyebab utama dalam pemanasan global. Kampus Universitas Indonesia, Depok terkenal atas banyaknya tumbuhan yang tumbuh dan ditanam, salah satunya adalah Adansonia digitata L. Adansonia digitata L. merupakan tumbuhan asli Afrika yang mampu mengikat karbon dioksida dalam jumlah besar. Daya serap karbon dioksida dapat dihitung dengan konversi massa karbohidrat menjadi massa karbon dioksida. Konversi massa karbohidrat menjadi massa karbon dioksida dapat dilakukan dengan menggunakan metode Nelson-Somogyi. Hasil tertinggi daya serap karbon dioksida sampel daun sebanyak 30 gram yang diambil dari 5 pohon pada 2 waktu pengamatan memiliki hasil sebesar 10,5624 gram. Sedangkan untuk nilai terendah yang didapatkan sebesar 1,54035 gram. Daya serap karbon dioksida pada A. digitata L. terbaik pada pukul 10.00 WIB karena pada proses fotosintesis berjalan optimal tanpa adanya pengaruh dari menutupnya stomata. Selain itu pada pukul 10.00 WIB, temperatur udara cenderung lebih rendah dibandingkan dengan temperatur pada pukul 12.00 WIB. Temperatur merupakan salah satu faktor yang berperan penting dalam proses fotosintesis.
The current condition of air quality in Indonesia is very volatile. Fluctuating air quality conditions can occur due to several factors. One of the factors that play a role in air quality is the intensity of carbon dioxide emissions in the air. Excess carbon dioxide can produce greenhouse gas emissions and is a major cause of global warming. The campus of the University of Indonesia, Depok is famous for the many plants that grow and are planted, one of which is Adansonia digitata L. Adansonia digitata L. is a plant native to Africa that is capable of binding large amounts of carbon dioxide. The absorption of carbon dioxide can be calculated by converting the mass of carbohydrates into mass of carbon dioxide. The conversion of carbohydrate mass into carbon dioxide mass can be carried out using the Nelson-Somogyi method. The highest yield of carbon dioxide absorption of leaf samples as much as 30 grams taken from 5 trees at 2 times of observation had a yield of 10.5624 grams. Meanwhile, the lowest value obtained was 1.54035 grams. The absorption of carbon dioxide in A. digitata L. was best at 10.00 WIB because at this time the photosynthesis process was running optimally without the effect of closing stomata. In addition, at 10.00 WIB, the air temperature tends to be lower than the temperature at 12.00 WIB. Temperature is one of the factors that play an important role in the process of photosynthesis."

Dampak konversi lahan terhadap daya serap karbon dioksida CO2 di kota Tangerang Selatan = Land conversion impact to carbon dioxide (CO2) absorption: case study Tangerang Selatan city
"Kebutuhan akan lahan untuk pemukiman mengakibatkan konversi tutupan lahan vegetasi menjadi non-vegetasi. Tangerang Selatan mengalami perubahan luas akibat konversi lahan vegetasi menjadi non-vegetasi mencapai 31,472 km2 dan proses konversi ini mengakibatkan kehilangan daya serap CO2 sebesar 98.212,022 kg CO2/ m2 dalam kurun waktu 10 tahun 2007-2017. Pola konversi lahan sangat terlihat pada Kecamatan Pondok Aren dengan perubahan luasan mencapai 7,632 km2. Korelasi antara nilai biomassa yang dipengaruhi oleh nilai NDVI dengan korelasi Pearson mencapai R2 = 0.627 yang berarti terdapat pengaruh sebesar 60 NDVI terhadap nilai biomassa. Model estimasi Biomassa oleh NDVI dengan pengukuran lapangan menghasilkan persamaan regresi lnY = 3969 X 1058.
The human need of land for settlements resulting to conversion of vegetation cover to non vegetation. A wide change of conversion occurred in Tangerang Selatan are primary from vegetation cover into non vegetation and reached about 31,472 km2. This conversion process resulted in absorption loss of CO2 amount 98,212,022 kg CO2 m2 in the period of 10 years 2007 to 2017. The pattern of land conversion is clearly seen at Pondok Aren Sub district with the change of area reaches 7,632 km2. The correlation between biomass value that is influenced by the value of NDVI with Pearson correlation reach R2 0.627 which means there is influence of 60 NDVI to the value of biomass. Biomass estimation model by NDVI with field measurement resulted to regression equation lnY 3969 X 1058."

Karakteristik sebaran ruang terbuka hijau serta hubungan dengan daya serap emisi karbon dioksida dan emisi karbon dioksida sisa di Jakarta Selatan = The characteristics of green open space distribution as well as its relation to the absorption capacity of carbon dioxide emission and residual carbon dioxide emissions in South Jakarta
"Pada tahun 1990-an sekitar dua pertiga dari emisi CO2 berasal dari negara-negara maju, namun emisi CO2 berasal dari negara berkembang seperti Indonesia yang merupakan negara nomor enam penghasil emisi terbesar di dunia. Kota Jakarta yang menjadi pusat kegiatan membuat kota Jakarta memiliki penduduk yang semakin banyak dan jumlah kendaraan yang meningkat. Kegiatan manusia salah satunya dalam dapat menghasilkan karbon dioksida dalam jumlah yang besar namun juga dapat menyerapnya kembali dengan adanya keberadaan RTH.
Penelitian ini bertujuan untuk mengetahui adanya hubungan sebaran ruang terbuka hijau serta hubungannya dengan daya serap emisi karbon dioksida dan emisi karbon dioksida sisa. Metode yang digunakan untuk pengambilan sampel yaitu purposive sampling dengan menetapkan titik sampel emisi di sepuluh kecamatan di Jakarta Selatan dan verifikasi nilai indeks vegetasi. Sebaran ruang terbuka hijau di tiap kecamatan di Jakarta Selatan menggunakan indeks fragmentasi. Variabel daya serap didapatkan dari luas tajuk vegetasi yang didapatkan dari Indeks Vegetasi yaitu LAI Leaf Area Index.
Emisi transportasi didapat dengan mengkonversi jumlah kendaraan dengan persamaan dan emisi dari pernapasan manusia didapatkan dari data jumlah penduduk. Variabel emisi sisa didapatkan dari total emisi dikurang oleh daya serap. Kemudian variabel sebaran ruang terbuka hijau dengan daya serap emisi karbon dioksida dan emisi karbon dioksida sisa dilakukan analisis korelasi menggunakan metode spearman rank untuk mengetahui ada atau tidak hubungan antar variabel.
Hasil dari penelitian ini yaitu adanya hubungan sebaran ruang terbuka hijau yang cenderung mengumpul dengan daya serap emisi karbon dioksida secara signifikan dengan nilai koefisien korelasi sebesar 0.79 tetapi antara sebaran ruang terbuka hijau dan daya serap emisi karbon dioksda dengan emisi karbon dioksida sisa tidak memiliki hubungan yang signifikan dan memiliki hubungan yang negative yang berarti semakin mengumpul ruang terbuka hijau, maka semakin besar daya serap emisi karbon dioksida dan semakin sedikit emisi karbon dioksida sisa.
In the 1990s about two thirds of CO2 emissions came from developed countries, but CO2 emissions come from developing countries like Indonesia, which is the world 39 s sixth largest emitters. The city of Jakarta which became the center of activity makes the city of Jakarta has a growing population and the number of vehicles increased. Human activities are one of them in producing large amounts of carbon dioxide but can also reabsorb it in the presence of green space.
This study aims to determine the relationship of green open space distribution as well as its relationship with the absorption of carbon dioxide emissions and residual carbon dioxide emissions. The method used for sampling is purposive sampling by setting emission sample point in ten sub districts in South Jakarta and verification of vegetation index value. Distribution of green open spaces in each sub district in South Jakarta using fragmentation index. The absorption variable is obtained from the vegetation canopy area obtained from Vegetation Index that is LAI Leaf Area Index.
Transport emissions are obtained by converting the number of vehicles with equations and emissions from human respiration obtained from population data. The residual emission variables obtained from total emissions are reduced by absorption. Then the variables of green open space distribution with the absorption of carbon dioxide emission and residual carbon dioxide emission are done by correlation analysis using spearman rank method to know whether or not the relationship between variables.
The result of this study is the relationship of green open spaces that tend to accumulate with the absorption of carbon dioxide emissions significantly with the value of correlation coefficient of 0.79 but between the green open space distribution and absorption capacity of carbon dioxide emissions with residual carbon dioxide emissions have no significant relationship and have a negative relationship which means getting the green open space, the greater the absorption capacity of carbon dioxide emissions and the less carbon dioxide emissions remaining."

Analisis Viabilitas Polen pada Beberapa Spesies Asteraceae di Lingkungan Kampus Universitas Indonesia = Pollen Viability Analysis of some Asteraceae Species from University of Indonesia Campus, Depok, Indonesia
"Asteraceae adalah famili tumbuhan dengan 1.900 genus dan 32.000 spesies. Asteraceae mudah tumbuh di berbagai habitat seperti tanah lapang, taman, dan sisi jalan raya. Pemetaan jenis Asteraceae di Kampus Universitas Indonesia telah dilakukan oleh Oktarina & Salamah (2017:243), dan morfologi polen beberapa Asteraceae di lingkungan kampus juga telah diteliti (Salamah dkk. 2019:154). Sementara itu, struktur komunitas beberapa Asteraceae di kampus sudah dikaji oleh Agassi (2017), tetapi viabilitas polen Asteraceae di lingkungan Kampus Universitas Indonesia belum diteliti. Studi ini bertujuan untuk mengevaluasi viabilitas polen beberapa spesies Asteraceae di Kampus Universitas Indonesia. Delapan spesies Asteraceae dari 6 tribes diamati melalui metode in vitro dengan tiga tipe medium dan pewarnaan menggunakan pewarna safranin 2%. Hasil viabilitas metode germinasi in vitro menunjukkan bahwa Synedrella nodiflora, Spaghneticola trilobata, dan Youngia japonica memiliki viabilitas polen tertinggi pada ketiga tipe medium, sementara Tridax procumbens dan Mikania micrantha memiliki viabilitas polen terendah. Selain itu, tidak terdapat perbedaan signifikan pada viabilitas polen masing-masing spesies dengan ketiga tipe medium, tetapi terdapat perbedaan signifikan pada viabilitas polen masing-masing spesies di setiap medium. Metode pewarnaan menunjukkan hasil yang berbeda dengan metode germinasi in vitro, namun sejalan dengan studi struktur komunitas Asteraceae yang telah dilakukan.
Asteraceae is a diverse plant family comprising 1,900 genera and 32,000 species, welladapted to various habitats, including open fields, gardens, and roadside areas. Mapping of Asteraceae species on the University of Indonesia campus has been conducted Oktarina & Salamah (2017:243). Salamah et al. (2019:154) explored the pollen morphology of several Asteraceae species within the same environment. Meanwhile, Agassi (2017) studied the community structure of various Asteraceae species on the campus. Research on the pollen viability of Asteraceae in the same setting has not been explored. This study aim to determine the pollen viability of several Asteraceae species in the University of Indonesia campus environment. The pollen viability of eight Asteraceae species from six tribes was observed using in vitro germination method with three types of medium and staining method with safranin 2%. The results of the in vitro germination method showed that Synedrella nodiflora, Spaghneticola trilobata, and Youngia japonica had the highest pollen viability on all three types of medium, while Tridax procumbens and Mikania micrantha had the lowest pollen viability. Moreover, there were no significant differences in the pollen viability of each species among the three types of medium, but there were significant differences in the pollen viability of each species within each medium. The staining method yielded different results compared to the in vitro germination method, but was consistent with the community structure study of Asteraceae."

Analisis determinan emisi karbon dioksida di Indonesia = Analysis of the determinants of carbon dioxide emission in Indonesia
"ABSTRAK
Tesis ini menganalisis determinan emisi karbon dioksida (CO2) di Indonesia dihubungkan dengan hipotesis Environmental Kuznets Curve (EKC). Permodelan empiris dilakukan dengan Simultaneous Equation Model (SEM) antara produk domestik bruto (PDB) per kapita dengan emisi CO2 dengan menggunakan data runtut waktu dari 1974 hingga 2011. Uji Hausman melihat hubungan simultan dan endogenitas dari PDB per kapita dan emisi CO2. Dengan metode Two-stage Least Squares (2SLS) diperoleh hasil hipotesis EKC berlangsung di Indonesia. PDB per kapita, peranan industri terhadap perekonomian, dan kepadatan penduduk berpengaruh signifikan meningkatkan emisi CO2. Namun demikian, konsumsi energi terbarukan tidak secara signifikan berpengaruh menurunkan emisi CO2.
ABSTRACT
This thesis analyzes determinants of carbon dioxide (CO2) emission in Indonesia associated with Environmental Kuznets Curve (EKC) hypothesis. Empirical modelling with Simultaneous Equation Model (SEM) between per capita gross domestic product (GDP) and CO2 emission by using time series data from 1974 to 2011. Hausman tests investigate simultaneous relationship and endogeneity between per capita GDP and CO2 emission. By Two-stage Least Squares (2SLS) method, results support Environmental Kuznets Curve (EKC) hypothesis. GDP per capita, share of industry, and population density significantly affect the increasing of CO2 emission. However, renewable energy consumption did not significantly affect the reducing of CO2 emission."

Penataan kawasan sekitar kampus Universitas Indonesia, Depok dengan pendekatan student city = University of Indonesia, Depok campus neighborhood design using student city approach
"Kota Depok saat ini terdapat banyak institusi pendidikan yang terus berkembang. Keberadaan institusi pendidikan tinggi ini tentunya akan membawa pengaruh pada kawasan sekitarnya, antara lain perubahan fungsi bangunan, perubahan sosial ekonomi dan adanya peningkatan volume lalu lintas akibat adanya pertambahan jumlah mahasiswa yang tinggal di sekitar institusi pendidikan tersebut. Disini, kehadiran perguruan tinggi menyebabkan terjadinya permintaan dari mahasiswa akan tempat tinggal, sehingga kawasan itu menjadi hunian yang memerlukan berbagai fasilitas pendidikan. Dan hal ini menyebabkan perkembangan pada kawasan tersebut.
Selain berperan penting terhadap perkembangan kawasan sekitar kampus, sebagai mahasiswa diharapkan juga dapat mengembangkan karakter dirinya guna menjalankan peran dan fungsinya di masyarakat. Namun hal ini tidaklah terlihat pada kawasan sekitar kampus Universitas Indonesia, Depok. Mahasiswa menjadikan kawasan hanya sebagai tempat tinggal. Peran dan fungsinya bagi masyarakat lokal masih belum terlihat. Hal ini dikarenakan mahasiswa belum dapat mengembangkan karakter dirinya atau bereksplorasi pada kawasan tersebut.
Tulisan ini berusaha untuk melihat dan menata kawasan sekitar kampus Universitas Indonesia dengan menggunakan pendekatan student city. Diharapkan agar kawasan dapat menjadi wadah mahasiswa dalam mengeksplorasikan dirinya, sehingga selain berguna bagi pengembangan dirinya, mahasiswa juga dapat menjalankan peran dan fungsinya di dalam bermasyarakat.
There are many educational institutons in Depok City that continue to grow. The existence of those educational institutions takes effects for the neighborhood, i.e. the changes of building fuction, social economics, and the increasing of traffic volume as the impact of the increasing number of student living around the educational institutions. The existence of higher education institutions causes the demand for residence that should be equiped with educational facilities. Those make the development of the area around the campus.
In addition to the important role for the development of the area around the campus, students are expected to be able to develop their character in order to carry out their role and function in society. But this is not seen in the area around the University of Indonesia, Depok. Students make the area only as a residence. Their roles and functions within local community are still not visible. That is because the students have not been able to develop their character and explore the area.
This article tries to view and organize the area around the campus of University of Indonesia using student city approach. It is expected that the area can a place for students in exploring themselves, so in addition to useful for their development, students can also perform their role and functions within the community."
