Judul: Glycemic Index Values of Instant Porridge Prepared from Cassava Starch and Cassava Resistant Starch
Abstrak: Resistant starch is a starch that indigestible by enzymes. Resistant starch has health benefits effect, one of which has a slow effect in increasing level of glucose in the blood. Several researchs have shown association between resistant starch content in foods with glycemic index. The objective of this study is to observe the glycemic index value of foods prepared from cassava starch and cassava resistant starch. Cassava resistant starch was made using one and three autoclaving-cooling cycles. Four instan porridges were used in this study namely cassava starch porridge, cassava modification starch prepared using one autoclaving-cooling cycle (one cycle) porridge, cassava modification starch prepared using three autoclaving-cooling cycle (three cycle) porridge, and cassava modification starch porridge with added protein and fat from soy protein isolate, vegetable oil, and eggwhite. The results of analyses showed that resistant starch content of cassava starch porridge, one cycle cassava modification starch porridge, three cycle cassava modification starch porridge, and cassava modification starch porridge with added protein and fat were 4.46% db, 7.09% db, 8.00% db and 5.09% db respectively while the in vitro starch digestibility of those porridges were 83.76% db, 77.94% db, 76.63% db, and 79.32% db respectively. Glycemic index value of cassava starch porridge, one cycle cassava modification starch porridge, three cycle cassava modification starch porridge, and cassava modification starch porridge with added protein and fat were 97.74, 93.69, 106.09, and 93.96 respectively. All porridges can be classified as high index glycemic index food product. Statistical test showed that resistant starch manufacturing process does not affect the glycemic index value (p>0.05).

Abstrak: Tujuan umum penelitian ini adalah untuk mempelajari proses pembuatan bubur instan dari bahan pati singkong termodifikasi. Tujuan khususnya adalah 1) Mempelajari modifikasi pati singkong dengan perlakuan autoclaving-cooling cycling; 2) Menyusun formula bubur instan berbasis pati singkong termodifikasi; 3) Menganalisis karakteristik fisikokimia pati singkong termodifikasi dan tepung bubur instan;4) Menganalisis pengaruh modifikasi terhadap karakteristik kimiawi pati singkong termodifikasi dan tepung bubur instan; 5) Menganalisis kandungan gizi pati dan serat pangan pati termodifikasi serta bubur instan; 6) Menganalisis kandungan energi dan harga energi serta serat pangan bubur instan sebagai pangan fungsional.Penelitian ini diharapkan dapat member manfaat bagi masayarakat dan industri pangan, khususnya pmberian alternative produk pangan berbasis pati singkong resisten. Tahapan penelitian ini terdiri dari beberapa tahapan. Tahapan tersebut terdiri dari 1) Pembuatan pati singkong termodifikasi; 2) Formulasi bubur instan; 3) Uji organoleptik bubur instan; 4) Analisis karateristik fisikokimia, kimiawi, dan kandungan gizi; 5) Analisis biaya pembuatan produk dan harga energi serta serat pangan pada bubur instan. Pembuatan pati singkong termodifikasi terdiri dari pati singkong tergelatinisasi dan pati singkong resisten dilakukan dengan metode autoclaving-cooling yang dimodifikasi. Proses modifikasi dilakukan dengan pengulangan siklus 1 kali dan 3 kali dengan waktu gelatinisasi masing-masing 30 menit dan 15 menit. Pati singkong termodifikasi digunakan untuk formulasi bubur instan. Formula bubur instan yang paling disukai dari uji organoleptik adalah formula bubur instan dengan penambahan tepung emulsi 15 gram. Hasil analisis karakteristik fisikokimia pati dan bubur instan menunjukkan bahwa pola gelatinisasi pati singkong dan pati singkong resisten menunjukkan pola yang berbeda dikarenakan proses pengolahan autoclaving-cooling meningkatkan kekentalan atau viskositas pati singkong dan menurunkan suhu gelatinisasi pati. Pengamatan granula pati pada pati singkong termodifikasi menunjukkan bahwa sifat birefringence semakin tidak terlihat jelas akibat degradasi amilosa yang menyebabkan pembengkakan granula saat autoclaving-cooling cycling. Derajat putih paling tinggi adalah pati singkong, sedangkan produknya adalah bubur pati singkong resisten 1 siklus. Densitas kamba yang tinggi pada pati singkong resisten 3 siklus (RS 3) dan tepung bubur instan pati singkong resisten 3 siklus (BRS 3) menyebabkan rasa kenyang yang lebih tahan lama daripada kedua jenis pati dan tepung bubur instan lainnya. Derajat putih tertinggi adalah pati singkong.

Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
