Uji kualitas udara indoor dengan parameter mikrobiologi di Rumah Sakit Muhammadiyah Taman Puring, Jakarta Selatan = Assessment of microbial indoor air quality at Muhammadiyah Hospital in Taman Puring South Jakarta / Annisa Pramesti Putri
"ABSTRAK
Kualitas udara mikrobiologi dalam ruangan di rumah sakit perlu diperhatikan terutama pada ruang poliklinik karena di ruang tersebut banyak pengunjung berkumpul dalam waktu yang bersamaan. Dengan demikian, peluang tersebarnya penyakit melalui udara oleh bakteri dan jamur patogen juga tinggi. Tujuan penelitian ini adalah untuk mengetahui konsentrasi bakteri dan jamur di udara pada ruangan di poliklinik, perbedaan konsentrasi bakteri dan jamur antar ruang poliklinik pada hari padat dan sepi pengunjung dan jenis bakteri berdasarkan pewarnaan gram. Sampel kualitas udara mikrobilogis diambil dengan menggunakan EMS E6 dengan menggunakan media TSA (Oxoid, 2011) untuk bakteri dan media MEA (Oxoid, 2011) untuk jamur dan dilakukan secara duplo. Pengambilan sampel dilakukan pada ruang poliklinik yang berbeda dan waktu yang berbeda dimana hari senin mewakili hari sepi dan sabtu mewakili hari padat pasien/pengunjung. Hasil sampling bakteri dan jamur diuji secara statistik dengan menggunakan statistik nonparametriks Pearson product moment dan two-tailed t-test. Hasil pengukuran sampel menunjukkan konsentrasi bakteri dan jamur telah melebihi baku mutu mengacu pada Peraturan Menteri Kesehatan RI No. 1204 Tahun 2004 yaitu rata-rata 2.545 ± 9,11 CFU/m3 untuk bakteri dan 306 ± 2,91 CFU/m3 untuk jamur. Konsentrasi bakteri dan jamur paling tinggi terdapat pada ruang Poliklink Umum. Uji statistik Pearson product moment menunjukkan jumlah pengunjung memiliki korelasi yang rendah (r = 0,29) dengan konsentrasi bakteri dan memiliki korelasi sedang (r = 0,45) dengan konsentrasi jamur. Selanjutnya, uji statistik two-tailed t-test menunjukkan bahwa tidak ada hubungan signifikan antara jumlah pengunjung dengan konsentrasi mikrobiologi di udara. Identifikasi bakteri dengan pewarnaan gram menunjukkan bahwa 84,2% bakteri yang ditemukan merupakan bakteri gram negatif dan 15,2% gram positif. Bakteri gram negatif berpotensi lebih besar dalam menginfeksi manusia karena memiliki endotoksin. Oleh karena itu, perlu dilakukan pemasangan filter HEPA atau ULPA pada sistem ventilasi (AC) untuk menurunkan konsentrasi bakteri dan perbaikan sistem ventilasi agar kelembaban ruangan terjaga antara 30-60% dan suhu ruangan dibawah 25oC sehingga dapat menurunkan konsentrasi jamur.
ABSTRACT
Microbial indoor air quality in hospital has to be considered, especially in the examining and waiting room because many people gathered at the same time. Hence, chances for spreading airborne disease by pathogenic bacteria and fungi are high. The objectives of this study are to find out indoor air bacteria and fungi concentrations at the examining room, the difference of bacteria and fungi concentrations during high and low numbers of visitors, and types of bacteria based on gram staining. Microbial air samples were taken in Duplo by using EMS E6 with TSA (Oxoid, 2011) and MEA (Oxoid, 2011) media for bacteria and fungi, respectively. Samplings were conducted on different examining rooms and days, which Monday and Saturday represented as low and high numbers of visitors, respectively. The sampling results tested statistically by using non-parametric statistical method, Pearson product moment and two-tailed t test. The measurement results showed that indoor air bacteria and fungi concentrations have exceeded the quality standards by Menteri Kesehatan RI No. 1204 in 2004, with the average are 2.545 ± 9.11 CFU/m3 and 306 ± 2.91 CFU/m3 for bacteria and fungi, respectively. The highest concentration of bacteria and fungi is found in examining room for children and general, respectively. Pearson product moment test showed a low correlation (r=0.29) between number of visitors and indoor air bacteria concentration and moderate correlation (r=0.45) between number of visitors and indoor air fungi concentrations. Furthermore, two-tailed t-test results showed that there was no significant relationship between number of visitor and indoor air microbial concentrations. Identification of bacteria with gram staining showed that 84.2% of bacteria found are gram-negative and 15.8% are gram-positive bacteria. The gram-negative bacteria are having greater possibly infected human than gram-positive bacteria because it has endotoxin. Therefore, it is necessary to install HEPA or ULPA filters on ventilation system (air conditioned) and maintain relative humidity between 30-60% and temperature below 25oC in the hospital to reduce indoor air bacteria and fungi concentrations"

"Teluk Kendari merupakan salah satu kawasan yang berdekatan dengan pusat kegiatan masyarakat. Kondisi seperti ini akan menyebabkan terjadinya ancaman di sekitar teluk berupa sedimentasi. Sedimentasi yang tinggi pada perairan mengakibatkan meningkatnya konsentrasi total padatan tersuspensi yang berdampak pada terhambatnya penetrasi cahaya pada perairan akibat terhalang oleh partikel sedimen. Sebagai konsekuensinya, tingginya konsentrasi TSS dapat menurunkan tingkat fotosintesis dan akan menurunkan kandungan klorofil-a dalam perairan tersebut. Penelitian ini bertujuan untuk, menganalisis karakteristik sedimen (ukuran butir), menganalisis sebaran total padatan tersuspensi dan klorofil-a serta mensintesa hubungan antara total padatan tersuspensi dengan kandungan klorofil-a. Penelitian ini dilakukan pada bulan januari sampai maret 2018. Metode yang digunakan dalam penelitian ini adalah metode survey dengan mengumpulkan data primer berupa data karakteristik ukuran butir sedimen, konsentrasi total padatan tersuspensi dan kandungan klorofil-a, serta data skunder berupa TSS dan Klorofil-a pada tahun 2010, 2015 dan 2018 yang diambil dari citra satelit Landsat 5 TM dan Landsat 8 OLI. Hasil penelitian ini menunjukkan karakteristik sedimen dengan ukuran butir yang paling halus berada pada wilyah tengah teluk yang dimana pada wilayah itu merupakan wilayah dengan kandungan TSS tertinggi sedangkan yang lebih besar berada pada mulut teluk. Total spadatan tersuspensi berpengaruh terhadap kandungan klorofil-a perairan yang ditunjukkan dengan nilai koefisien determinasi (R2) sebesar 0.79 yang berarti sebesar 79% variable TSS mempengaruhi kandungan klorofil-a.
Kendari Bay is one of areas adjacent to the center of community activities at Southeast Sulawesi. Such conditions will cause a threat around the bay in the form of sedimentation. High sedimentation in the waters resulted in increas of total suspended solid (TSS) concentration. As a light light penetration in the will be low. TSS usually consist of < 2 I¼m. High TSS concentrations can reduce photosynthesis levels and the chlorophyll-a content in waters. This study was aimed to analyse the sediment grain size, the distribution patterns of total suspended solids and chlorophyll-a and tosynthesize the correlations between total suspended solids and chlorophyll-a content. This research was conducted in January to March 2018. The method used in this study was the survey method by collecting primary data such as sediment grain size, total suspended solid concentration and chlorophyll-a content, and secondary data such as TSS and chlorophyll-a in 2010, 2015 and 2018 taken from the image Landsat 5 TM and Landsat 8 OLI satellites. The results of this study indicated that the characteristics of sediments with the finest grain size was in the middle of the bay while the larger ones were at the mouth of the bay which is the region with the highest TSS content. TSS affected the chlorophyll-a content of waters as shown by the coefficient of determination (R2) of 0.79 which means that 79% of the TSS variable affects the chlorophyll-a content."

Tinjauan hukum mengenai ekoregion sebagai paradigma perencanaan lingkungan hidup dalam kaitannya dengan penataan ruang di Indonesia = Legal review of the ecoregion principle as a paradigm of environmental planning related to spatial planning in Indonesia
"ABSTRAK
Asas ekoregion ditetapkan oleh Undang- Undang Nomor 32 Tahun 2009 sebagai
paradigma perencanaan lingkungan hidup di Indonesia. Asas ekoregion
menegaskan bahwa perlindungan dan pengelolaan lingkungan hidup harus
memperhatikan karakteristik sumber daya alam, ekosistem, kondisi geografis,
budaya masyarakat setempat dan kearifan lokal. Akan tetapi, asas ekoregion belum
diterapkan di dalam penataan ruang sebagaimana penataan ruang merupakan bagian
dari perlindungan dan pengelolaan lingkungan hidup. Tujuan dari penelitian ini
adalah untuk menemukan bahwa belum terdapat kesesuaian/sinkronisasi asas
ekoregion sebagai paradigma perencanaan lingkungan hidup berdasarkan UU No.
32/2009 dengan penataan ruang di Indonesia, sehingga prinsip pembangunan
berkelanjutan belum terwujud. Berdasarkan hal tersebut, maka perlu diadakan
sinkronisasi antara perencanaan lingkungan hidup khususnya asas ekoregion di
dalam penataan ruang
ABSTRACT
Ecoregion principle was established by Law No. 32 of 2009 as a paradigm of
environmental planning in Indonesia. Ecoregion principle affirms that the
protection and management of the environment, should pay attention to the
characteristics of natural resources, ecosystems, geography, local culture and local
wisdom. However, ecoregion principle has not implemented yet especially in
spatial planning as it a part of environmental protection and management. The
objective of this thesis is to find that there was no synchronization and conformity
between ecoregion principle as a paradigm of environmental planning based on
Law No. 32 of 2009 related to spatial planning in Indonesia, so that sustainable
development has not reached yet. This thesis give suggestions to afford the
synchronization between environmental planning, especially the ecoregion
principle in the spatial planning"

Perhitungan jejak karbon dari aktivitas kampus di Universitas Indonesia = Carbon footprint calculation based on campus activities at The Universitas Indonesia
"Universitas merupakan salah satu lingkup kecil suatu negara yang turut menyumbang emisi gas rumah kaca yang memicu pemanasan global dan perubahan iklim. Walaupun lingkupnya cukup kecil, namun universitas menjadi bagian yang sangat berpengaruh bagi pengembangan dan kemajuan suatu negara, termasuk dalam konsep mitigasi dampak perubahan iklim lokal. Universitas Indonesia UI adalah salah satu universitas yang telah berkomitmen untuk menjadi kampus hijau di tengah Kota Depok. Oleh karenanya, banyak diadakan penelitian yang mengarah kepada konsep keberlanjutan kampus hijau tersebut. Untuk mengetahui pengaruh aktivitas kampus terhadap lingkungan, dilakukan perhitungan emisi jejak karbon. Beberapa aktivitas kampus yang dimaksud adalah penggunaan energi listrik, penggunaan bahan bakar LPG di kantin, transportasi, pemakaian kertas, dan timbulan sampah di semua fakultas di Kampus UI Depok. Perhitungan besarnya emisi yang dihasilkan kampus dilakukan dengan menggunakan metode IPCC 2006, yakni mengalikan konsumsi aktivitas dengan faktor emisi terkait. Hasil perhitungan dan analisis setiap sektor menunjukkan jumlah emisi gas rumah kaca yang dihasilkan dari kelima sektor tahun 2015 hingga tahun 2017 berturut-turut sebesar 88181,47 tCO2-eq, 78764,01 tCO2-eq dan 76482,87 tCO2-eq. Dari total emisi yang ada, penyumbang emisi dari sektor listrik, transportasi, dan pemakaian kertas terbesar adalah Fakultas Teknik, sedangkan sektor bahan bakar LPG dan timbulan sampah paling besar disumbangkan oleh Fakultas Ekonomi dan Bisnis. Berdasarkan proyeksi emisi gas rumah kaca GRK hingga tahun 2030 dengan menggunakan metode aritmatika untuk kondisi bussiness as usual, diperoleh bahwa emisi GRK pada tahun 2030 akan bernilai sebesar 48064 tonCO2eq. Karena timbulan sampah mengalami penurunan dari tahun 2015 hingga 2017, maka timbulan sampah hingga tahun 2030 pun diproyeksikan akan cenderung mengalami penurunan. Skenario penurunan emisi mengacu pada target pemerintah dalam menurunkan emisi GRK dari yang dapat dilakukan UI berdasarkan kelima sektor tersebut. Skenario ini antara lain meliputi Solar PV, bahan bakar biogas, pemberlakuan satu hari bebas kendaraan dalam seminggu, penggunaan kertas bolak-balik dan sistem digital, serta penerapan konsep bank sampah di fakultas. Hal ini menjadi salah satu faktor yang membuat emisi GRK menurun sebesar 29 atau sekitar 13938,51 tonCO2eq.
University is one of the small scope of a country that contribute to greenhouse gas emissions that triggers global warming and climate change. Although the scope is relatively small, university is a very influential part of the development and progress of a state, including the concept of mitigating the impacts of local climate change. Universitas Indonesia UI is one of the universities that has committed to be a green campus of the city of Depok. These leads to the conduct of many studies addressing the concept of green campus sustainability. To determine the effect of campus activity on the environment, the carbon footprint emission is calculated. The campus activities included are the use of electrical energy, the use of LPG fuel in the canteen, transportation, paper usage, and waste generation in all faculties at Depok UI Campus. The amount of emissions generated is calculated using the IPCC 2006 method, which is to multiply the activity consumption by the associated emission factor. The results of the calculation and analysis of each sector shows that the amount of greenhouse gas emissions generated from the five sectors in 2015 until 2017 are amounted up to 88181,47 tCO2 eq, 78764,01 tCO2 eq and 76482,87 tCO2 eq correspondingly. Of the total emissions, the largest contributor of emissions from the sector of electricity, transportation, and paper usage is the Faculty of Engineering, while emissions from LPG fuel sector and waste generation are mostly contributed by the Faculty of Economics and Business. Greenhouse gas GHG emissions are projected up to the year of 2030 by using arithmetic method for business as usual condition, from which it is concluded that, by 2030, GHG emissions will have a value of 48064 tonCO2eq. Waste generation from 2015 to 2017 has decreased, thus it is projected that the waste generation until 2030 will tend to decrease. Emission reduction scenarios grounded on government targets in reducing total GHG emissions from UI can be implemented based on the 5 sectors. This scenario includes solar PV, biogas fuel, weekly car free day, usage of paper back and digital system, and the concept of garbage bank applied within the faculty. This scenario is one of the factors that make GHG emissions decreased by 29 or about 13938,51 tonCO2eq."
