Judul: Drone Utilization for Species Identification and Population Estimation of Waterbird in Suaka Margasatwa Pulau Rambut
Abstrak: Drone merupakan instrumen modern yang dapat digunakan sebagai alat bantu kegiatan pemantauan burung air, namun informasi yang tersedia mengenai tata cara pelaksanaan menggunakan alat ini masih minim. Penelitian ini bertujuan mengidentifikasi faktor yang mempengaruhi detektabilitas drone terhadap burung air, mengidentifikasi jenis yang terdeteksi drone, memetakan distribusi sarang air, dan membandingkan estimasi populasi yang dihasilkan oleh drone dan survei darat. Penelitian ini menggunakan 3 drone; MJX Bugs4W, DJI Mavic 2 Enterprise DUAL, dan DJI Matrice 300 RTK. Penelitian dilaksanakan pada bulan Juli-Agustus 2021 di Suaka Margasatwa Pulau Rambut. Faktor-faktor yang mempengaruhi detektabilitas adalah morfologi burung air, ketinggian terbang, sensor, cara terbang, dan kemampuan terbang drone. Survei udara dengan drone mengidentifikasi 7 jenis burung air, sedangkan survei darat mengidentifikasi 6 jenis. Survey udara (1033 ind.) mendeteksi lebih sedikit populasi burung air daripada survei darat (3390). Hasil perhitungan sarang melalui orthomosaic berbeda dengan estimasi populasi, di mana sarang yang terdeteksi melalui survei udara lebih banyak (683 titik) daripada survei darat (124 titik).

Judul: Stakeholder Analysis related to Habitat Quality of Waterbirds in Pulau Rambut Wildlife Sanctuary, DKI Jakarta
Abstrak: Suaka Margasatwa Pulau Rambut (SMPR) merupakan habitat 15 spesies burung air dengan populasi antara 4.500 ekor hingga 24.000 ekor. Habitat burung air di SMPR tercemar oleh sampah laut yang kebanyakan berasal dari Pulau Jawa. Penelitian ini bertujuan untuk mengidentifikasi stakeholder yang memiliki pengaruh dan kepentingan terhadap kualitas habitat burung air di SMPR, mengklasifikasi stakeholder berdasarkan tingkat pengaruh dan kepentingannya, serta merumuskan hubungan antar stakeholder. Data yang dikumpulkan berupa identitas stakeholder, pengaruh dan kepentingan stakeholder, serta hubungan antar stakeholder yang diperoleh melalui wawancara semi terstruktur, observasi lapang, dan studi literatur. Data dianalisis dengan matriks pengaruh-kepentingan dan actor linkage matrix. Terdapat sepuluh stakeholder yang teridentifikasi, terdiri dari pemerintah, kelompok masyarakat, lembaga pendidikan, LSM dan komunitas. BKSDA DKI Jakarta memiliki pengaruh dan kepentingan tertinggi serta menjalin hubungan dengan seluruh stakeholder karena stakeholder ini memiliki wewenang untuk mengelola SMPR., Pulau Rambut Wildlife Sanctuary (PRWS) is the habitat of 15 waterbirds species with a population between 4,500 to 15,000 individuals. Waterbird habitat in PRWS is polluted by marine litter, mostly from Java. The purpose of this research is to identify stakeholders who have influence and interest in habitat quality of waterbirds, classify stakeholders based on their influence and interest, and define relationship between stakeholder. The collected data consists of stakeholder identity and function, influence and interest of stakeholders, and relationships between stakeholders. These data were collected through semi-structured interviews, field observations, and literature studies. The collected data were analyzed using influence and interests matrix and actor-linkage matrix. There are 10 identified stakeholders, consist of government, social community, educational institutions, NGO, and community. BKSDA DKI Jakarta has the highest influence and interest score, build relationships with all stakeholders, and play a dominant role as main actors because it has authority to manage PRWS.

Judul: Sintesis Flavon dari Fenol dan Benzoil Klorida
Abstrak: Flavone is a class of flavonoid, commonly found in plants with wide bioactivity spectrum. A widely used flavone synthesis route is through acidcatalyzed oxidative cyclization of β-diketone. In this study, unsubstituted flavone had been synthesized via 5-step from phenol, with 22% yield and successfully increased the yield of previous study on Fries rearrangement of phenyl acetate and benzoylation of o-HAP steps. Phenol was acetylated resulting 93% phenyl acetate. AlCl3-catalyzed Fries rearrangement in 1.5 hour and at 120 °C converted phenyl acetate into o-hydroxyacetophenone (o-HAP) with 40% yield. AlCl3 as catalyst produced o-HAP with higher and reproducible yield compared with BF3·Et2O and ZnCl2. Benzoylation of o-HAP followed by Baker-Venkataraman rearrangement of the ester product using KOH in dried pyridine produced β-diketone 1-(2- hydroxyphenyl)-3-phenylpropane-1,3-dione. The yield of ester and β-diketone were 71% and 85%, respectively. Finally, oxidative cyclization of β-diketone with sulphuric acid as catalyst produced 99% of flavone. The flavone product had been characterized spectroscopically and its melting point as well.
