Judul: Identifikasi Potensi Jalur Wisata Birdwatching di Cluster Northridge Sentul City, Bogor
Abstrak: Birdwatching tourism is an environment friendly activity that can be implemented for supporting eco-city concept in Sentul City. The goal of this research is to identify birds species in five observation trails, identify the trails that potential for birdwatching tourism and make recommendation for birwatching tourism trail. Identificationof birdwatching trails had been conducted in Cluster Northridge Residence, from May until July 2013. Collecting data from literature review and field observation. The results showed that the richness of bird was 36 species from 21 family. The fourth trail which was Telaga Indah street had the highest number of birds whereas the first trail which was Bukit Permata 1 had the lowest number of birds. The potential trail for birdwatching tourism was fourth trail because it had highest biodiversity of birds and the unique birds, such as collared kingfisher (Halcyon chloris), javan kingfisher (Halcyon cyanoventris), small minivet (Pericrocotus cinnamomeus) and black-crowned night-heron (Nycticorax nycticorax). Visitors can do the birdwatching tourism with walking and riding on horseback.

Judul: Bird Community as a Potential Birdwatching Tourism in Buperta Cibubur Urban Forest
Abstrak: Hutan Kota Buperta Cibubur sebagai ruang terbuka hijau dengan fungsi rekreasi dan edukasi cukup potensial untuk wisata birdwatching. Penelitian ini bertujuan mengidentifikasi jenis dan kelimpahan burung, mendeskripsikan sebaran spasial dan temporal burung, serta membuat rekomendasi jalur dan waktu wisata birdwatching. Penelitian ini dilakukan pada Maret-April 2022. Pengumpulan data burung dilakukan menggunakan metode encounter rates dan metode daftar jenis MacKinnon pada lima jalur pengamatan. Total jenis burung yang ditemukan yaitu sebanyak 39 jenis dari 25 famili. Jalur Hutan dan Lahan Terbangun memiliki jumlah jenis terbanyak sedangkan jalur Tegakan Rawang 2 memiliki jumlah jenis paling sedikit. Jalur Lahan Terbangun memiliki kelimpahan burung tertinggi. Beberapa jenis burung dapat ditemukan di seluruh jalur pengamatan. Waktu yang paling efektif untuk menemukan berbagai jenis burung adalah 6.00-7.00 dan 16.31-17.30. Jalur Lahan Terbangun, Hutan, dan Lahan Terbuka berpotensi untuk wisata birdwatching karena memiliki kekayaan dan kelimpahan tinggi dengan beberapa jenis burung yang potensial. Waktu yang direkomendasikan untuk melakukan birdwatching pada setiap jalur berbeda sesuai dengan kondisi jalur., The Urban Forest of Buperta Cibubur as a green open space with recreational and educational functions has quite potential for birdwatching tourism. This study aims to identify the species and abundance of birds, describe the spatial and temporal distribution of the birds, and make track and time recommendations for birdwatching tourism. This study was conducted in March-April 2022. Bird data was collected using the encounter rates and MacKinnon species list method on five observation tracks. The total species of birds found were 39 species from 25 families. Forest and the Built-up Land track had the highest number of species, while the Sparse Vegetation 2 had the least number of species. The Built-up Land track had the highest bird abundance. Several types of birds can commonly be found on all tracks. The most effective time to see various species of birds is 6.00-7.00 and 16.31-17.30. The Built-up Land, Forest, and Open Land tracks have the potential for birdwatching tourism because they have high species richness and abundance with several potential bird species. The recommended time for birdwatching on each track is different according to the track conditions.

Judul: Sintesis Glukosa Oleat dengan Berbantuan Gelombang Mikro
Abstrak: Carbohydrate-based esters of fatty acids are nonionic surfactants which are nontoxic, odorless, tasteless, and biodegradable. Glucose oleic acid is one of them. It can be synthesized by reacting glucose pentaacetate (GPA) and methyl oleate with conventional heating for 6 hours, which is slow and time-consuming. Therefore, organic synthesis has been developed by employing microwave irradiation, so called Microwave- Assisted Organic Synthesis (MAOS). This research synthesized glucose oleic acid, from GPA and methyl oleate using MAOS method, to reduce time of reaction and better yield. The parameters observed were melting point (for GPA), free fatty acid content (for methyl oleate), functional group analysis using Fourier transformed infrared spectroscopy (FTIR), and percent of yield. Reaction between GPA and glucose oleic acid was transesterification, while those of methyl oleate was esterification. GPA and glucose oleic acid using MAOS gave faster time of reaction, 5-10 minutes. The results showed that GPA, methyl oleate, and glucose oleic acid were well synthesized, as shown by FTIR spectra. The yield of GPA was 68,52%, with melting point was 94–111 °C. Methyl oleate gave 95,69% yield. Free fatty acid content of methyl oleate was 2,23%. The yield of glucose oleic acid was 47,18%.
