Judul: Development of Chicken Essence Drink from Kampung Chicken for Adolescent Aged 10-15 Years
Abstrak: Pengembangan Minuman Sari Pati Ayam Berbahan Dasar Ayam Kampung untuk Remaja Usia 10-15 Tahun. Dibimbing oleh AHMAD SULAEMAN. Sari pati ayam sebagai suplemen makanan menyediakan protein yang dibutuhkan selama proses tumbuh-kembang remaja usia 10-15 tahun. Tujuan penelitian ini adalah mengembangkan minuman sari pati ayam berbahan dasar karkas ayam kampung dengan perlakuan umur potong yang berbeda. Desain penelitian ini adalah penelitian eksperimental yang menggunakan karkas ayam umur 4 bulan (F1), 8 bulan (F2), 12 bulan (F3), dan produk komersial (F0) sebagai pembanding. Seluruh formula dan produk komersial memiliki 25 atribut sensori yang teridentifikasi melalui analisis deskriptif kuantitatif (QDA). Daya terima seluruh formula lebih baik dibandingkan dengan produk chicken essence komersial. Formula terpilih berdasarkan hasil uji organoleptik dan kadar protein terbaik adalah formula berbahan dasar karkas ayam kampung berumur 12 bulan (F3) dengan kadar air, abu, protein, lemak, dan karbohidrat berturut-turut sebesar 81,29%bb, 3,04%bk, 17,61%bk, 3,49%bk, dan 75,87%bk. Asam amino pembatas dari formula adalah asam amino sulfur (AAS). Kontribusi zat gizi formula terpilih terhadap acuan label gizi (ALG) usia umum per takaran saji (140 mL) sebesar 4,9 % energi, 7,7 % protein, 1,4 % lemak, 6,1 % karbohidrat, dan 6,7 % branch-chained amino acids (BCAA). Kata Kunci: ayam kampung, protein, remaja, sari pati ayam, Development of Chicken Essence Drink from Kampung Chicken for Adolescent Aged 10-15 Years. Supervised by AHMAD SULAEMAN. Essence chicken (CE) as a dietary supplement provides protein needed during the growth process of adolescents aged 10-15 years. The objective of this study is to dvelop CE drink from kampung chicken carcass with different slaughter age. The design of this study is an experimental study that uses 4 m.o (F1), 8 m.o (F2), 12 m.o (F3), and commercial product as comparisons (F0). Every formulas and F0 had 25 sensory attributes identified in quantitative descriptive analysis (QDA). Every formula had better acceptance rate compared to commercial product. The selected formula is F3 with highest score of organoleptic test and the best protein content. This formula contains water 81,29 % wb, ash 3,04% db, protein 17,61% db, fat 3,49% db, and carbohydrate 75,87% db. The limiting amino acid in this product is sulphuric amino acids (SAA). This contribution of nutrients to product based on daily reference value (RDV) for general age per serving size (140 mL) are 4,9 % energy, 7,7 % protein, 1,4 % fat, 6,1 % carbohydrate, and 6,7 % BCAA.

Judul: Performa Ayam Kampung yang Diberi Campuran Pakan Berupa Dedak Padi dan Daun Singkong (Manihot esculenta Crantz
Abstrak: Kampung chicken is often cultivated in Indonesia in semi-intensive and extensive. This chicken has slower growth than broiler. A four weeks kampung chicken old has weight 0.20 kg while broiler has weight 1.2 kg, but kampung chicken could digest crude fiber more than 5% of the nutrient content of the feed. Rice and cassava are widely grown in lowland as well as highland and their residual processing can be used as feed. The purpose of this study was to investigate the performance of kampung chicken fed rice bran and cassava leaves. Rice bran and dried cassava leaves were stirred in warm water before feeding to the chickens. Treatment feed was given to the chickens aged 5-12 weeks (P2) and 8-12 weeks (P3) in pasta form. The control (P1) was given commercial feed at the age of 0-12 weeks. The analysis showed the feeding method influences the body weight of kampung chicken. The highest body weight showed in P1 with lowest feed conversion. The lowest body weight showed in P2 with highest feed conversion. Treatment P3 resulted body weight and feed conversion between P1 and P2. The highest mortality (13.33%) showed in P2. Rice bran and cassava leaves were good to give to kampung chicken in 9 weeks to replace commercial feed.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
