Judul: Formulasi Biskuit Rendah Indeks Glikemik (BATIK) dengan Subtitusi Tepung Pisang Klutuk (Musa balbisiana Colla) dan Tepung Tempe
Abstrak: Penelitian ini bertujuan untuk memformulasi biskuit rendah Indeks Glikemik (IG) substitusi tepung pisang klutuk dan tepung tempe dengan menggantikan penggunaan tepung terigu. Pisang merupakan salah satu bahan pangan lokal yang berpotensi untuk dikembangkan dan memiliki IG rendah (46-51). Pisang klutuk dipilih karena penggunaannya sebagai pangan masih terbatas. Tempe berpotensi untuk digunakan sebagai sumber protein pengganti tepung terigu, selain diketahui mempunyai IG rendah. Penelitian dilakukan menggunakan Rancangan Acak Lengkap dengan empat faktor proposi penambahan tepung pisang klutuk yaitu 0% (F0), 20% (F1), 30% (F2) dan 40% (F3). Subtitusi tepung tempe sebesar 5% pada F1-F3. Peningkatan subtitusi tepung pisang klutuk menurunkan penerimaan panelis terhadap biskuit dari suka menjadi agak tidak suka. Formula terpilih berdasarkan mutu kimia dan uji organoleptik yaitu biskuit F1 dengan skor rata-rata penerimaan panelis biasa sampai suka. Biskuit F1 mengandung kadar air 4.88%, kadar abu 2.03%, kadar protein 7.53%, kadar lemak 28.12%, serat kasar 1.87%, karbohidrat 56.23%, Aw 0.43, serat pangan 13.5%, total pati 44.54%, daya cerna pati 60.4%, tingkat kekerasan 1511.5 gf, dan warna 0hue 69 (kuning merah). Nilai IG biskuit tepung pisang klutuk adalah 36 dan termasuk rendah. Biskuit pisang klutuk dapat dijadikan salah satu alternatif pangan fungsional terutama bagi penyandang diabetes.

Judul: Formulasi Biskuit Substitusi Tepung Ubi Kayu dan Ubi Jalar dengan Penambahan Isolat Protein Kedelai serta Mineral Fe dan Zn untuk Balita Gizi Kurang
Abstrak: Moderate undernutrition is one of major nutritional problems in Indonesia, with a prevalence of 13%. Instead of lack of energy and protein intake, undernutrition children commonly are deficient in iron and zinc. One of the effort to overcome this problem is by giving them foods which contain high energy and protein as well as met with iron and zinc requirement. The objective of this research was to formulate biscuit which were made of cassava flour, sweet potato flour, and soy protein isolate with addition of Fe and Zn as side dish of moderate undernutrition children. Cassava and sweet potato flour is an indigenous food of Indonesia which high in energy content, so can be used to substitute wheat flour in making biscuits as source of energy. To increase protein content of biscuit, it was used soy protein isolate which contains about 90% protein. Gizikita is a multivitamin mineral supplement containing high iron and zinc in microcapsules form. Design of this research was experimental which factors that used were kind of flour (cassava, sweet potato, and composite flour) and level of flour substitution (20%, 40%, and 60%). Based on organoleptic test showed that the selected formula was A1B1 (20% cassava substitution). Biscuits A1B1 has 457 Kcal/100g of gross energy; 2.960,2 gram force of hardness; 8,31% water content (wb); 3,12% ash (db); 13,93% protein (db); 14,23% fat (db); 68,71% carbohydrate (db); 8,38 mg/100g Fe; 10,61 mg/100g Zn; 81,48% protein digestibility; 10,87% bioavailability of Fe ; and 29,45% bioavailability of Zn.

Judul: Daily Behavior of Axolotl (Ambystoma mexicanum) in Aquarium Maintenance
Abstrak: Ambystoma mexicanum atau axolotl adalah salamander yang termasuk jenis eksotis dari Meksiko. Salamander ini potensial dipelihara sebagai hewan eksotis didukung insang eksternal dan warna kulit yang bervariasi. Pemeliharaan axolotl masih menjadi masalah utama, karena dapat menurunkan kesejahteraan hidup axolotl apabila informasi terbatas bagi pemelihara. Kesejahteraan hidup dipengaruhi oleh kondisi hewan dan kondisi lingkungan. Penelitian bertujuan mempelajari perilaku harian axolotl berdasarkan warna kulit, jumlah individu di akuarium, dan periode waktu. Pemeliharaan axolotl dilakukan di akuarium dengan suhu 22,3–23,0 °C serta pencahayaan (12/12 jam). Objek penelitian terdiri dari axolotl dengan warna kulit merah muda (leucistic), kuning (golden), dan kecoklatan berbintik hitam (marble). Observasi perilaku harian axolotl menggunakan metode focal animal sampling dengan total 264 jam pengamatan. Perilaku harian yang diamati meliputi sosial, agonistik, dan lokomosi. Data dianalisis menggunakan uji ANOVA. Hasil penelitian menunjukkan interaksi antara warna kulit, jumlah individu, dan periode waktu tidak memengaruhi perilaku harian axolotl. Masingmasing faktor periode waktu dan jumlah individu mempengaruhi perilaku harian axolotl. Faktor warna kulit hanya memengaruhi perilaku sosial. Axolotl golden paling banyak melakukan aktivitas sosial. Axolotl lebih banyak beraktivitas pada siang hari daripada malam hari. Populasi tiga individu di akuarium meningkatkan perilaku sosial dan agonistik, namun menurunkan lokomosi, Ambystoma mexicanum or axolotl is an exotic type of salamander from Mexico. Axolotl has the potential as an exotic animal because of its external gills and varied skin color. Axolotl maintenance is still a major problem, which could reduce the welfare if the information is limited for keepers. The animal and environmental conditions influence welfare. The research aims to study the daily behaviour of axolotls based on skin color, number of individuals, and time period. Axolotl was maintained in an aquarium with temperature (22.3–23.0 °C) and lighting (12/12 hours). The objects consisted of axolotls in pink (leucistic), yellow (golden) and brownish skin with black spots (marble). Daily behaviour were observed by focal animal sampling (total of 264 hours). Daily behaviours included social, agonistic, and locomotion. Data were analyzed with an ANOVA test. The results showed that interaction between skin color, number of individuals and time period didn’t affect the daily behaviour of axolotls. The time period and the number of individuals influenced daily behaviour. The skin color only influenced social behaviour. Golden axolotl carried the most social activities. Axolotls were more active during the day than at night. Populations of three individuals in an aquarium increased social and agonistic, but decreased locomotion.
