Judul: Small islands utilization model (a case study of Pari islands in Kepulauan Seribu)
Abstrak: Pulau-pulau kecil memiliki karateristik yang unik, antara lain : berukuran kecil, terisolasi, ketergantungan, dan rentan. Namun demikian, dikaruniai sumberdaya yang katanya melimpah. Dalam pemanfaatannya, perlu pendekztan ekosistem penataan ruang yang harus didasarkan pada daya dukung ekologis, jaringan sosial budaya, dan integrasi kegiatan sosial ekonomi yang ada. Oleh karena itu, perlu suatu model pemanfaatan yang dapat mendasari pembuatan kebijakan pengelolaan pulau-pulau kecil, yang terkuantifikasi dan terukur, serta berkelanjutan., Even though small islands have some disadvantage characteristics as smallness, isolation and vulnerable to natural disasters, they are nevertheless endowed with abudance natural resources which cloud be exploited for the benefit of humsn being. Given such dual characteristic, utilization of small islands must take into account several factors affecting the management of small islands. These include, ecology, economy and socio-economy characteristics. Therefore, an integrated utilization model is sorely needed to address the complex management of small islands.

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: Validation method for determination of apigenin in extract celery with high performance liquid chromatography
Abstrak: Apigenin is an active substance derived from celery (Apium graveolens) and widely used for the treatment of gout. Determination method of apigenin which have been validated was introduced by Frankee et al. J Food Compos Anal 17: 1-35 (2005). Apigenin analysis was done by high performance liquid chromatography (HPLC). To make sure that HPLC analysis method can be used for the intended purpose then the method was validated. Parameters determined on method validation were linearity, limit of detection, limit of quantification, precision, and accuracy. All parameters were in accordance with the acceptance criteria of Association of Official Analytical Chemist. The linearity in the concentration of 3,8; 5,7; and 7,6 mg/l had correlation coefficent of 0,9900–0,9998. limit of detection in this method was 2,7222 mg/l and limit of quantification was 8,2500 mg/l. Interday precision in five restating showed good precision with relative standard deviation of 3,85%. Accuracy was determined by standard addition method with recovery percentage of 95,00–118,77%. Average concentration of apigenin is 0,0052% (w/w).
