ABSTRACTKnowledge of community structures and capacity to differentiate invasive from non invasive species are essential for invasive species management. Specific Leaf Area SLA is a potential proxy to differentiate invasive species from non invasive species. This study aims to describe the community structure of Asteraceae family, identify the relationship between Important Value Index IVI with SLA of Asteraceae species, and predict Asteraceae habitat preference based on shade characteristics at the Cibodas Botanical Garden. The community structure data were obtained by measuring the extent of leaf cover and the presence of each Asteraceae species. SLA data were collected by measuring the leaf area and leaf dry weight. The study was conducted on 138 of 1x1 m plots in eight compartments which equally divided into two habitat conditions with and without tree canopy cover shading. Plots were sampled by using purposive sampling method. Linear regression analysis conducted to examine the correlation between SLA and IVI values of Asteraceae species. Logistic regression test conducted to observe habitat preference 1 for shaded area and 0 for open area of Asteraceae species based on SLA values. According to survey results, there are 20 species of Asteraceae, with Emilia sonchifolia as the species with largest IVI value 26,85. In general, there are no dominant Asteraceae species in all observed eight compartments D 0,14 0,40, the diversity of Asteraceae species is low to moderate H rsquo 1,31 2,12, and the distribution of Asteraceae species tends to be evenly distributed E 0,6 0,89. There is a positive correlation between SLA and IVI value of Asteraceae species in shaded area with predicted addition of 0,0014599 logINP per one SLA unit increase r2 0,1472 at p 0,07148. The Asteraceae species that prefer shaded habitat tend to have larger SLA relative to species in open area odds ratio 2,75. "

"Famili Asteraceae tercatat memiliki spesies terbanyak yaitu 162 spesies yang termasuk dalam kategori invasif karena memiliki karakter khusus antara lain tumbuh di lingkungan yang tidak menguntungkan, menghasilkan biji yang banyak, tingkat perkembangbiakan yang tinggi dan kemampuan dalam penyebaran biji. Pertumbuhan Asteraceae dipengaruhi oleh intenistas cahaya. Salah satu cara yang dapat digunakan untuk melihat pengaruh intensitas cahaya terhadap tanaman yaitu dengan keberadaan naungan. Karakter Specific Leaf Area (SLA) pada tumbuhan akan memberikan respons terhadap naungan yang akan mempengaruhi fotosintesis dan kandungan nitrogen (N) di tanah. Penelitian ini bertujuan untuk mengetahui hubungan antara naungan dengan respons SLA dan nilai Specific Leaf Area (SLA) dari Synedrella nodiflora, Mikania micrantha dan Tridax procumbens. Penelitian dilakukan di lingkungan Kampus UI, Depok selama 4 bulan dari bulan Februari hingga Juni 2019 dengan metode purposive random sampling. Pengambilan sampel dibagi dalam 7 kompartemen di area terbuka dan tertutup dengan menggunakan kuadrat berukuran 1x1 m. Jumlah plot terbuka dan tertutup yang ditemukan sebanyak 71 plot. Berdasarkan hasil penelitian, terdapat hubungan yang kuat dan tidak searah antara naungan dengan SLA yang artinya bila intensitas cahaya mengalami kenaikan maka nilai SLA akan menurun atau sebaliknya. Nilai SLA untuk masing-masing spesies memperoleh nilai lebih tinggi di plot tertutup dibanding plot terbuka.

The Asteraceae family has the highest species, 162 species included in the invasive category because they have special characteristics such as growing in an unfavorable environment, producing many seeds, high breeding rates and the ability to distribute seeds. Asteraceae growth is affected by light intensity. One way that can be used to see the intensity of light on plants is to use shade. Specific Leaf Area (SLA) characters in plants will respond to shade that will affect photosynthesis and nitrogen (N) content in the soil. This study aimed to study the correlation between shade and SLA response and the value of Specific Leaf Area (SLA) from Synedrella nodiflora, Mikania micrantha and Tridax procumbens. The research was conducted at campus UI, Depok for 4 months from February to June 2019 with a purposive random sampling method. Sampling is divided into 7 compartments in the open and closed area with a square of 1x1 m. The number of open and closed plots found was 71 plots. Based on the results of the study, there is a strong and unidirectional relationship between shade and SLA which means that if the light intensity increases then the SLA value will decrease or vice versa. SLA values for each species scored higher in closed plots than in open plots."

"Dalam era peningkatan minat terhadap energi terbarukan, pembangkit listrik tenaga biogas (PLTBg) telah menjadi alternatif yang menarik untuk menggantikan pembangkit listrik berbasis sumber non-terbarukan, seperti batu bara. PLTBg menggunakan biomassa sebagai bahan baku, seperti limbah pertanian, limbah daun, dan limbah makanan, yang kemudian dikonversi menjadi biogas melalui metode anaerobic digestion. Namun, penerapan PLTBg pada skala yang lebih kecil, seperti lingkungan universitas, masih belum banyak dilakukan. Penelitian ini bertujuan untuk menganalisis kelayakan pembangunan PLTBg di lingkungan Universitas Indonesia. Melalui simulasi di Aspen Plus menggunakan skema model pembangkit semi-kontinu dengan reaktor batch, penelitian ini menunjukkan bahwa PLTBg di lingkungan universitas dapat menghasilkan biogas sebanyak 1097,24 kg per hari dengan tingkat yield 50,4% dari 2177,18 Kg biomassa yang diumpankan. Listrik net yang dihasilkan mencapai 322,27 kWh per hari dengan jumlah total investasi sebesar $185.963. Selanjutnya, dengan metode blended financing antara green sukuk dan pinjaman bank yang dipilih, analisis keuangan menunjukkan hasil positif, dengan nilai Net Present Value (NPV) sebesar $112.137, Internal Rate of Return (IRR) sebesar 12,50%, dan Payback Period (PBP) sebesar 9 tahun. Namun, untuk menjaga keseimbangan antara Levelized Cost of Electricity (LCOE) dan harga listrik yang ditetapkan pemerintah, diperlukan skema subsidi dari pemerintah atau rektorat Universitas Indonesia. Analisis risiko menggunakan metode Monte Carlo menunjukkan tingkat keyakinan yang tinggi terhadap 10,000 variasi skenario jumlah produksi listrik tahunan (AEP) dan LCOE, dengan persentase 85,95% untuk nilai NPV positif dan 86,97% untuk IRR di atas 8%. Hasil ini menunjukkan bahwa pembangunan PLTBg ini memiliki potensi investasi yang menguntungkan berdasarkan hasil analisis finansial dan analisis risiko.

In an era of increasing interest in renewable energy, biogas power plants (PLTBg) have become an attractive alternative to power generation based on non-renewable sources, such as coal. PLTBg uses biomass as a raw material, such as agricultural waste, leaf waste, and food waste, which is then converted into biogas through the anaerobic digestion method. However, the application of PLTBg on a smaller scale, such as in university settings, has not been widely implemented. This study aims to analyze the feasibility of PLTBg development within the University of Indonesia. Through simulations at Aspen Plus using a semi-continuous generator model scheme with a batch reactor, this research shows that PLTBg in a university environment can produce as much as 1097.24 kg of biogas per day with a yield rate of 50.4% from 2177.18 Kg of biomass feed. The electricity generated reaches 322.27 kWh per day with a total capital investment of $185,963. Furthermore, using the blended-financing method between green sukuk and selected bank loans, financial analysis shows positive results, with a Net Present Value (NPV) of $112,137, Internal Rate of Return (IRR) of 12.50%, and Payback Period (PBP) of 9 years. However, to maintain a balance between the Levelized Cost of Electricity (LCOE) and the set electricity price from the government, a subsidy scheme from the government or the University of Indonesia rectorate is needed. Risk analysis using the Monte Carlo method shows a high degree of certainty in the variability of scenarios of changes in the amount of annual electricity production (AEP) and LCOE by 10,000 times, with a percentage of 85.95% for positive NPV values and 86.97% for IRR above 8%. These results indicate that the construction of PLTBg has a profiTabel investment potential based on the results of financial analysis and risk analysis."

"Tingginya angka kematian ibu masih menjadi masalah yang kompleks, dikarenakan adanya faktor yang melatarbelakangi kematian ibu yaitu terjadinya tiga keterlambatan. Dan salah satunya adalah keterlambatan di tingkat keluarga dalam mengenali tanda bahaya, dan membuat keputusan untuk segera mencari pertolongan. Secara umum penelitian ini bertujuan untuk mengetahui bagaimana peran serta keluarga, terutama suami terhadap kesehatan maternal dan bagaimana pola pengambilan keputusan dalam keluarga terkait dengan komplikasi perinatal. Penelitian ini menggunakan metode kualitatif dengan pendekatan fenomenologi. Jumlah partisipan enam pasang suarni istri yang berada di Desa Bojongherang Kecamatan Cianjur Kabupaten Cianjur dengan berbagai pengalaman yang terkait dengan komplikasi perinatal. Hasil wawancara pada enam pasang partisipan didapatkan informasi bahwa pengambil keputusan dalam keluarga umunnnya adalah suami, kecuali pada partisipan istri yang bekerja, istri mempunyai wewenang untuk mengambil keputusan. Proses pengambilan keputusan pada keenam pasang partisipan umumnya secara musyawarah. Meski hanya pada keluarga dengan istri bekerja keputusan diambil berdasarkan kesepakatan bersama. Sedangkan yang lainnya pengambilan keputusan dikembalikan pada pihak suami. Faktor yang paling berpengaruh dalam pengambilan keputusan yang terkait dengan komplikasi perinatal, adalah faktor sosioekonomi dan kepemilikan askes serta pengetahuan keluarga akan komplikasi perinatal. Faktor lain yang berpengaruh namun tidak terlalu dominan, yaitu status perempuan, pendidikan, dan budaya. Pengambilan keputusan yang tepat dan cepat diperlukan bila terkait dengan komplikasi perinatal karena dampak dari keterlambatan yang terjadi dapat mengakibatkan kematian baik maternal maupun perinatal. Perawat maternitas, hendaknya mengantisipasi berbagai faktor yang berpengaruh pada pengambilan keputusan dalam keluarga, yang terkait dengan komplikasi perinatal terutama dalam hal edukasi yang akan menumbuhkan kesadaran masyarakat tentang tanda dan bahaya terjadinya komplikasi. Sehingga tercapainya tujuan utama seorang perawat maternitas terhadap kesehatan maternal, yaitu dapat menjaga kesehatan keluarga tetap optimal untuk meyakinkan siklus yang optimal pada fase childbearing dan childbearing.

The high number of maternal mortality rate caused by 3 complex problems. One of those problems was delay identification by the family on the risk factors of the maternal and makes decision in seeking help related to their problem. The goal of this study was to identify how the family involvement role, especially their husband, to the maternal health and how the decision making pattern in the family, related to the prenatal complication. This study is qualitative research using phenomenology approach. The number of participant iii this study were six couples husband and wife who live in Bojongherang, Cianjur, west lava. The findings were identified that most of the decision maker in the family were the husbands, except those wife who are the carrier woman. In general, the process of decision making start with discussion from both husband and wife before the decision making is made. Some other is decided by their husband instead. The most influenced factors to the decision making process were socio-economic, accessibility to the health insurance and the family knowledge on the prenatal complications. The other less influenced factors were gender, educational background and cultural background. The proper and the exact time of decision making are needed in order to prevent the risk to the pregnant mother and their fetus. Therefore, the maternity nurse should anticipate factors that may give influence to the decision making in the family, especially those related to the prenatal complication, by educating people on recognizing the sign & symptom of early prenatal complication. As a result, the main goal of maternity nursing in maintaining the optimum level of family health can be achieved includes in ensuring the optimum cycle in the stage of childbearing and childrearing."

The existence of green space within a large area in the cities allegedly can affect its microclimate conditions. This study aims to analyze the role of Bogor Botanical Gardens in surface temperature and humidity variation to its the surrounding area. Air temperature and humidity variations data were obtained from ground measurements at 45 locations on the weekdays and weekends using stratified proportional random sampling then used to obtain comfort index using Thom rsquo s Discomfort Index. The land surface temperature and vegetation canopy cover are processed from Landsat 8 imagery to determine the park cooling intensity and vegetation conditions.

The result of spatial analysis with overlay method which is reinforced by Pearson correlation shows that the pattern of surface temperature and humidity are different on the weekdays which tend to increase and the weekends which tend to decrease along with the increase of the distance from Bogor Botanical Garden. The area around Bogor Botanical Garden is dominated by very uncomfortable area with 27 30 Thom 39 s discomfort index and park cooling intensity range from 0,3 5oC. The park cooling intensity and comfort index are significantly correlated to vegetation canopy cover and not correlated with the distance from the park."

"ABSTRACTBiological control of postharvest diseases of fruits and vegetables byantagonistic microorganism seems increasingly promising to replace the use of synthetic fungicides which are subjected to some limitation due to development of fungicides-resistant strain of the pathogens and risk for consumers and the environment (Lima et al, 1999). Several species of yeast have been reported to reduce postharvest fungal decay on fruits. One of the antagonistic yeast that has been use as commercial biocontrol is Metchnikowia fructicola in Shemerm product (Vero et al., 2002) Yeast Rhodotomla has been studied for the postharvest biologicalcontrol various mould pathogens on various fruit (Castoria et al., 1997).University of Indonesia Culture Collection (UICC) have Rhodotorula spp.strains from plants of Cibodas Botanical Garden, and moulds frompostharvest decayed-tomatoes and plants. The ability of these yeast strains as biocontrol agents against has not been reported.This thesis consists of two parts. Part 1 is entitled The antagonisticActivity of Rhodotorula spp. from Cibodas Botanical Garden Against Tomato Plant Infected-Causing Moulds. Part 2 is entitled The Potential of Rhodotorula sp. UICC Y-381 as Biocontrol Agent of Aspergillus ochraoeus on Postharvest Tomatoes. The objectives of this research are to obtain a potential Rhodotorula sp. with antagonistic activity against tomato infected-causing moulds, and to obtain infoimation on the ability of Rhodotorula sp. UICC Y- 381 as a biocontrol agent in reducing the severity of decay by Aspergillus ochraceus. The research was carried out in Laboratory of Microbiology, Department of Biology, and Center of Excellence Indigenous Biological Resources-Genome Studies (CoE IBR-GS), Faculty of Mathematics and Natural Sciences, from July 2008-July 2009.Yeast Malt Agar (YMA) was used for yeast growth medium, and PotatoDextrose Agar (PDA) was used for maintenance of fungi. The media PDA and Potato Dextrose Agar (PDB) were used for antagonistic test.Six strains of Rhodotorula spp. (Rhodotorula sp. UICC Y-318,Rhodotorula sp. UICC Y-325, Rhodotorula sp. UICC Y-332, Rhodotorula sp. UICC Y-381, Rhodotomla sp. UICC Y-384, and Rhodotorula sp. UICC Y-386) were investigated as antagonistic yeasts against Aspergillus ochraceus D1.2.2.SSM3, A. terreus D2.2.MC, and Drechslera sp. D1.3.MC. The yeasts were obtained from plants of Cibodas Botanical Garden, and the moulds were obtained from decayed tomatoes and infected plants, belonging to the University of Indonesia Culture Collection (UICC). Antagonistic test by strip method was carried out by usingconcentration of yeast cells at (1 .2-5.2) x 10° CFU/ml, and A. ochraceusD1.2.2.SSM3 at 4.7 x 10? CFU/ml, A. terreus D2.2.Mc at 3.2 x 10° CFU/ml,and Drechslera sp. D1.3.MC at 5.2 x 10? CFU/ml. Inoculation of the yeastcells on PDA was carried out 4 hours earlier before inoculation of mouldspores on petri dishes. Results showed that highest percentage reduction of mould colonies was shown by Rhodotorula sp. UICC Y- 325 againstDrechslera sp. (28.12%-72.14%), followed by Rhodotorufa sp. UlCC Y-381 against A. ochraoeus (54.28%-72.46%), and Rhodotoruta sp. Y-318 against A. terreus (21.76% - 58.10%) during 6-day incubation.Antagonistic test by co-culture method was carried out by usingconcentration of yeast cells at (1 .58-5.59) x 10° CFU/ml, and Aspergillus ochraceus D1.2.2.SSM3 at 7 x 10? cFU/ml, A. terreus D2.2.MC at 1.5 x 10? CFU/ml. Inoculation of the yeast cells on PDB was carried out 8 hours earlier before inoculation of mould spores on broth medium. Results showed that highest percentage reduction of conidial heads and hyphal width was shown by Rhodotorula sp. UICC Y-381 against A. ochraceus (9.45% and 12.43%; 7.10% and 7.51 %, after 2- and 3-day incubation, respectively). Rhodotorula sp. UICC Y-332 reduced conidial heads of A. terreus (10.17% and 9.60% after 2- and 3-day incubation) but, was not able to reduce hyphal width of A. terreus. Microscopic observation by slide culture method on PDA showed that there was attachment of Rhodotorula spp. cells to the hyphae of Drechslera sp., however, Rhodotorula spp. UICC Y-386 attached more intensively and colonized the hyphae.The ability of Rhodotorula sp. UICC Y-381, which was isolated fromplant leaves, as a biocontrol agent against postharvest tomato fruit decay- causing mould Aspergillus ochraceus D1 .2.2.SSM3 was evaluated. Observation was carried out for 15 days at 25°C - 27°C. Results showed that Rhodotorula sp. UICC Y-381 was able to reduce the severity of decay by A.ochraceus with 100% reduction until day-12, when compared to control. The synthetic fungicide Dithane M-45 at a concentration of 0.08% reduced the severity of decay to 100% until 15-day incubation."
