Judul: Uji Sifat Fisik Dan Evaluasi Kecernaan Biskuit Berbasis Rumput Lapang Dan Limbah Tanaman Jagung Pada Domba
Abstrak: The objective of this experiment was to determine the physical characteristic of corn plant waste after formed as a biscuit and evaluate the digestibility of the diet given to sheep based on field grass and corn plant waste. The experimental design used by Completely Randomized Design with 4 treatments and 3 replications. The treatments were : R1 (100% field grass); R2 (50% field grass + 50% corn leaf); R3 (100% corn leaf); and R4 (50% corn leaf + 50% corn husk). Consentrate was also given to sheep to fulfill its nutrient requirement. The results were subjected to ANOVA and Duncan Test, correlation among the variables was determined by linier regretion technique (Steel and Torrie, 1993). Biscuit variables measured were density (loose bulk density and tapped bulk density), particle size (average particle size and median particle size). Feed digestibility evaluation were dry matter, organic matter, crude fiber, NDF, ADF and crude protein. Average particle size (D) was about 447.71-669.64 μm and median particle size (D50) was about 206.08-321.29 μm. Modulus of fineness (MF) was about 2.10-2.68 and modulus of uniformity (MU) was variated; R1= 0:3:7 ; R2=R4= 0:5:5 and R3= 0:6:4. Loose bulk density (LBD) of the biscuits ranged about 173-225 kg/m3 and tapped bulk density (TBD) ranged about 185-239 kg/m3. According to the particle size which was determined on modulus of fineness (MF), all of the biscuits were defined as “fine” particle. Results showed that biscuits formula had gave very significant effect (P<0.01) on Density (LBD and TBD) and particle size (D and D50). Negative correlation was shown by the equation y= 0.3146-0.0002x, r= 75.47 % between average particle size (D) and LBD. The results of digestibility test indicated that the treatments had gave very significant effect (P<0.01) on dry matter digestibility, neutral detergent fibre digestibility, and acid detergent fibre digestibility, but gave no significant effect on organic matter digestibility, crude fiber digestibility, and crude protein digestibility.

Judul: Uji Kualitas Sifat Fisik dan Palatabilitas Biskuit Limbah Tanaman Jagung sebagai Substitusi Sumber Serat untuk Domba
Abstrak: Limbah tanaman jagung merupakan produk limbah yang berasal dari tanaman jagung dengan serat kasar yang cukup tinggi. Limbah tersebut dapat dimanfaatkan untuk pakan ternak. Produk limbah yang digunakan dalam penelitian ini yaitu daun dan klobot jagung. Selain limbah tanaman jagung, rumput lapang juga digunakan sebagai pakan kombinasi dan pembanding dengan limbah tanaman jagung. Kelemahan limbah tersebut yaitu bersifat voluminous (bulky) dan kemampuan produksi yang berfluktuasi sehingga diperlukan proses teknologi untuk mengubah limbah tanaman jagung tetap tersedia serta mudah disimpan. Masalah-masalah tersebut dapat diatasi dengan mengolah limbah tanaman jagung menjadi biskuit. Biskuit merupakan hasil pengolahan pakan melalui proses pemanasan dan pemadatan yang memiliki bentuk bulat dan tipis serta memiliki diameter dan tebal sebagai dimensinya. Penelitian ini dilakukan di Laboratorium Industri Pakan, Laboratorium Nutrisi Ternak Perah, Departemen Ilmu Nutrisi dan Teknologi Pakan, Fakultas Peternakan, Institut Pertanian Bogor dan pengujian palatabilitas dilakukan di Mitra Tani Farm (MT Farm), Desa Tegal Waru RT 04 RW 05, Kecamatan Ciampea, Kabupaten Bogor. Penelitian ini dilaksanakan mulai bulan Juli sampai bulan Oktober 2009.

Judul: Integration of Islamic Stock Markets of OIC Countries Before and During the Russia-Ukraine War Crisis
Abstrak: Pasar saham yang terintegrasi memberikan dampak negatif seperti percepatan co-movement (pergerakan bersama) yang rentan terhadap guncangan ekonomi, maupun krisis pasar global ke pasar domestik. Salah satu krisis yang terjadi pada tahun 2022 adalah perang Rusia-Ukraina yang berdampak pada pasar saham, termasuk pada saham syariah yang dipercaya lebih tahan terhadap guncangan krisis global. Penelitian ini bertujuan untuk meneliti perkembangan, integrasi dan respon lima pasar saham syariah negara OKI pada perang Rusia-Ukraina. Metode yang digunakan adalah VAR/VECM pada indeks DJIMMT25, SPSADS, SPSUAEDS, JII, DJIMT, SPBMIR, dan SPBMIU. Hasil penelitian menunjukkan pergerakan yang sama pada pasar saham UAE dan Arab Saudi, sedangkan Turki mengalami tren positif selama perang. Pasar saham syariah negara OKI selama periode perang Rusia-Ukraina terkointegrasi, sementara pasar saham Malaysia memengaruhi pasar saham syariah empat negara OKI lainnya. Hasil IRF menunjukkan terdapat efek permanen pada volatilitas pasar saham syariah negara OKI akibat guncangan yang diberikan. Namun, respon volatilitas relatif kecil karena kontribusi guncangan lebih didominasi oleh pasar saham itu sendiri, An integrated stock market has negative impacts, such as accelerating co-movement, which is vulnerable to economic shocks and global market crises on the domestic market. One of the crises in 2022 was the Russia-Ukraine war which impacted the stock market, including Sharia stocks which were believed to be more resistant to the shocks of the global crisis. This study examines the development, integration, and response of OIC countries five Islamic stock markets in the Russia-Ukraine war. The method used is VAR/VECM on the DJIMMT25, SPSADS, SPSUUAEDS, JII, DJIMT, SPBMIR, and SPBMIU indices. The results show the same movement in the UAE and Saudi Arabia stock markets, while Turkey experienced a positive trend during the war. The Islamic stock market of the OIC countries during the Russia-Ukraine war was cointegrated. In contrast, the Malaysian stock market influenced the Islamic stock markets of the other four OIC countries. The IRF results show a permanent effect on the volatility of the Islamic stock market in OKI countries due to the shocks given. However, the volatility response is relatively small because the stock market itself dominates the contribution of shocks.
