Judul: Applying Risk Assessment Approach to Evaluate Small Island Status in Seribu Island
Abstrak: Kepulauan Seribu terdiri dari 110 pulau, diantaranya Pulau Harapan, Pulau Kelapa, dan Pulau Kelapa Dua yang dijadikan lokasi penelitian. Ketiga pulau dengan potensi yang dimiliki perlu direalisasikan pengelolaan secara terpadu kawasan pesisir dan lautan untuk pembangunan berkelanjutan. Proses pembangunan pulau-pulau kecil secara terpadu di ketiga pulau perlu mempertimbangkan risiko-risiko yang akan terjadi. Tujuan penelitian ini untuk menganalisis tingkat risiko di pulau-pulau kecil dan memperkirakan pengelolaan pulau-pulau kecil yang sesuai untuk kawasan Kepulauan Seribu. Metode yang digunakan dalam penelitian ini yaitu metode survei dan observasi dengan analisis model IPCC (2014). Jenis bahaya yang paling berpotensi menimbulkan bencana adalah angin puting beliung, sedangkan gelombang, abrasi dan sampah tidak berpotensi menimbulkan bencana. Tingkat kerentanan di Pulau Harapan, Pulau Kelapa dan Pulau Kelapa Dua tergolong rendah, karena hanya ada satu bahaya yang berpotensi bencana yaitu angin puting beliung dengan besaran dan kerugian yang diakibatkan cukup besar. Tingkat kapasitas yang di miliki oleh ketiga pulau cukup baik, sehingga didapatkan nilai risiko di Pulau Harapan 0,69, Pulau Kelapa 0,68, dan Pulau Kelapa Dua 0,62 yang termasuk ke dalam kategori rendah.

Judul: Smart System Algorithm Design to Measure the Feasibility of Investment in Coastal and Small Islands (Case Study: Seribu Islands Regency)
Abstrak: Pemanfaatan pulau-pulau kecil dan kawasan pesisir di Indonesia membu-tuhkan perencanaan yang baik. Sistem informasi dapat membantu proses perencanaan dengan mempermudah penilaian kelayakan dan penyebaran informasi. Penelitian ini bertujuan untuk mengaplikasikan sistem informasi penilaian ke-layakan investasi pulau-pulau kecil pada lima pulau kecil yang terdapat di Kecama-tan Kepulauan Seribu Utara. Pengamatan dilaksanakan pada Bulan Agustus 2020 dan data sekunder diperoleh melalui studi pustaka. Analisis basis ekonomi dil-akukan menggunakan Location Quotient dan Shift share Analysis dengan hail sektor usaha akomodasi dan pengelolaan sampah berpotensi kuat untuk dikem-bangkan, sedangkan sektor komunikasi memiliki pertumbuhan yang cepat dibandingkan sektor yang sama di Provinsi DKI Jakarta. Penggunaan sistem infor-masi menunjukan Pulau Harapan dan Pulau Kelapa sebagai pulau kecil yang siap menerima investasi sedangkan Pulau Bulat, Pulau Dolphin, dan Pulau Perak belum siap untuk menerima investasi., Utilization of small islands and coastal areas in Indonesia requires good planning. Information systems can assist the planning process by facilitating feasi-bility assessment and dissemination of information. This research aims to apply the information system for investment feasibility assessment of small islands on five small islands located in the North Thousand Islands Subdistrict. Observations were conducted in August 2020 and secondary data was obtained through library studies. Economic base analysis are conducted using Location Quotient and Shift share Analysis with hail of accommodation and waste management business sector has strong potential to be developed, while the communication sector has rapid growth compared to the same sector in DKI Jakarta Province. Field observations are pro-cessed with an information system for assessing the investment feasibility of small islands. The results of the information system show Harapan Island and Kelapa Island as small islands that are ready to receive investment while Bulat Island, Dol-phin Island, and Perak Island are not ready to receive investment.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
