Abstrak: The objective of this research was to make the cookies from modified arrowroot starch which have high resistant starch content, so that it can be used as functional food which have low glycemic index. The research consisted of three steps: arrowroot extraction, starch modification, and cookies making. The extraction of arrowroot produced 15.69% starch. Starch modification by autoclaving-cooling cycles was run in 3 cycles with 15 minutes gelatinization period in each cycle. Then, modified arrowroot starch was used as main ingredient in the making of cookies. Cookies from wheat were also made as comparison. Physical properties analyzed were breaking strength, color degree, and water activity. Chemical properties analyzed were proximate analysis, starch digestibility, amylose content, starch content, resistant starch content, and total dietary fiber content. Glycemic index was also analyzed for cookies from modified arrowroot starch and cookies from wheat. Breaking strength of cookies as measured by Texture Analyzer XT-21 showed that the force required to break the cookies significantly decreased with substitutions of wheat with modified arrowroot starch. The use of modified arrowroot starch resulted in the increase of amylose content, total dietary fiber content, and resistant starch content of cookies. It also could reduce starch digestibility of cookies. The glycemic index of cookies from modified arrowroot starch was 31. This value was lower than glycemic index of cookies from wheat that was 44. This was because higher amylose content, total dietary fiber content, and resistant starch content and lower starch digestibility of cookies from modified arrowroot starch than cookies from wheat. It means that the use of modified arrowroot starch as main ingredient in the making of cookies can decrease glycemic index of cookies.

Abstrak: Arrowroot starch has potential as raw material to produce resistant starch. Like other sources of starch, arrowroot starch naturally has low resistant starch content. Modification treatment of arrowroot starch for increasing resistant starch content in this research are acid hydrolysis, threeautoclaving- cooling-cycles, and HMT using heated for 15 minutes (HMT15’) and 60 minutes (HMT60’). The objectives of this research are to study the increased of resistant starch, amylose content and reducing sugar content, and also the decreased of starch digestibillity and total starch; to obtain modification method of arrowroot starch (acid hydrolysis, threeautoclaving- cooling-cycles, HMT, and or combination of acid hydrolysis, three-autoclaving-cooling-cycles, and HMT) for producing the highest resistant starch content; and also to obtain the best heat time of HMT between 15 minutes and 60 minutes at 1210C for increasing resistant starch content. Arrowroot starch modification by using combination of acid hydrolysis method, three autoclaving-cooling cycles, and HMT using heated for 60 minutes increased resistant starch content (from 2.15% to 29.63%), amylose content (from 24.50% to 35.83%), and reducing sugar (from 4.92% to 10.20%), and also decreased both starch digestibility (from 84.92% to 54.12%) and total starch content (from 98.10% to 71.28%). Treatment in arrowroot starch modified by using acid hydrolysis method, threeautoclaving- cooling-cycles and HMT60 minutes (HAAC-HMT60’) increased resistant starch content until 14 times fold compared to native arrowroot starch. That combination of treatment (HAAC-HMT60’) has been proven significantly (P<0.05) to increase resistant starch, amylose content, reducing sugar content and also decrease both starch digestibility and total starch from modified arrowroot starch.

Abstrak: Kepulauan Seribu ditetapkan sebagai Kawasan Taman Nasional Laut Kepulauan Seribu (TNLKS)pada tahun 1984. Di kawasan TNLKS terdapat dua institusi pemerintah (Balai TNLKS) dan institusi lokal masyarakat Kepulauan Seribu (kearifan lokal). Penelitian ini bertujuan untuk mendiskripsiakn pelaksanaan konservasi SDPL oleh Balai TNLKS, menganalisis sistem pengelolaan sumberdaya pesisir dan laut berbasis masyarakat, menganalisis respon nelayan terhadap aturan Balai TNLKS dan konflik-konflik yang menyertainya serta menganalisis resolusi konflik yang terjadi.
