Abstract

ABSTRAKPenelitian ini bertujuan untuk mengkaji efek pemanfaatan sabut kelapa terfermentasi dalam ransum sapi terhadap kecernaan nutrien. Ransum yang digunakan merupakan pakan komplit yang disusun menggunaan sabut kelapa terfermentasi dengan level berbeda. Percobaan menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 5 kelompok cairan rumen yang berbeda. Ransum perlakuan berupa T1 = Pakan komplit (sabut kelapa fermentasi 15%), T2 = Pakan komplit (sabut kelapa fermentasi 20%), T3 = Pakan komplit (sabut kelapa fermentasi 25%), T4 = Pakan komplit (sabut kelapa fermentasi 30%). Parameter yang diukur meliputi kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO), kecernaan lemak kasar (KcLK) dan Total Digestible Nutrients (TDN). Data yang didapat diolah menggunakan analisis ragam dengan taraf 5% dan apabila menunjukkan adanya pengaruh nyata dilanjutkan dengan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa penggunaan sabut kelapa terfementasi dalam ransum tidak berpengaruh pada KcBK, KcBO dan KcLK dengan nilai rataan berturut-turut 52,88; 52,62; 48,84% namun berpengaruh nyata (P<0,05) terhadap nilai TDN yaitu pada T4 meningkat sebesar 57,28%. Disimpulkan bahwa penggunaan sabut kelapa terfermentasi dalam ransum dengan level berbeda tidak mempengaruhi nilai KcBK, KcBO dan KcLK namun  pada level 30% mampu meningkatkan nilai TDN sebesar 57,28%.Kata Kunci: kecernaan, sabut kelapa, fermentasi, in vitroThe Effect of Use of Fermented Coconut Husk in Beef Cattle Ration On In Vitro Nutrient DigestibilityABSTRACTThis study aims to examine the effect of using fermented coconut husk in rations on nutrient digestibility. The ration used is a complete feed prepared using fermented coconut husks at different levels. The experiment used a randomized block design (RBD) with 4 treatments and 5 different groups of rumen fluid. Treatment rations in the form of T1 = complete feed (15% fermented coconut husk), T2 = complete feed (20% fermented coconut husk), T3 = complete feed (25% fermented coconut husk), T4 = complete feed (30% fermented coconut husk). The parameters measured included dry matter digestibility (KcBK), organic matter digestibility (KcBO), crude fat digestibility (KcLK) and Total Digestible Nutrients (TDN). The data obtained were analyzed based on analysis of variance with a level of 5%, and if the treatment had a significant effect, it was continued with the Duncan multiple range test. The results showed that the use of cementated coconut husk in the ration had no effect on KcBK, KcBO and KcLK with a mean value of 52,88 respectively; 52.,62; 48,84% but had a significant effect (P <0.05) on the TDN value, namely the increase in T4 was 57,28%. It was concluded that the use of fermented coconut coir in different levels of ration did not affect the value of KcBK, KcBO and KcLK but at the level of 30% it was able to increase the TDN value by 57,28%.Keywords: digestibility, coconut husk, fermentation, in vitro

Abstract

Air Tak Berekening atau Tingkat Kehilangan Air (TKA) pada Badan Usaha Air Minum (PDAM) menjadi perhatian bagi banyak kalangan. Artikel ini menjelaskan pendekatan proses penurunan kehilangan air dimulai dari penilaian, perumusan dan implementasi strategi pada PDAM Kota Semarang. Proses dimulai dengan melakukan penilaian TKA melalui penyusunan neraca air dan analisis komponen di tingkat perusahaan. Hasil penilaian ini kemudian diterjemahkan menjadi strategi di tingkat perusahaan. Dengan sumber daya yang telah dialokasikan, PDAM melalui bagian Penurunan Kehilangan Air melakukan penilaian TKA di tingkat zona atau Sistem Penyediaan Air Minum (SPAM) dan di District Metered Area (DMA) untuk merumuskan strategi di tingkat taktis. Langkah yang dilakukan bagian Penurunan Kehilangan Air adalah dengan melakukan penurunan TKA secara fokus di satu SPAM dengan memanfaatkan tim pencarian kebocoran dan Internet of Things (IoT) data logger. Implementasi strategi dilaksanakan dengan pendekatan model konseptual DMAIC (Define-Measure-Analyze-Improve-Control) pada semua DMA di SPAM tersebut sampai tercapainya target. Proses ini terbukti berhasilkan menurunkan TKA di salah satu SPAM dari 39% menjadi 26%. Harapannya, artikel ini dapat menjadi contoh penilaian, perumusan, dan implementasi strategi penurunan tingkat kehilangan air bagi PDAM. Kata kunci: Tingkat Kehilangan Air, penilaian, neraca air, analisis komponen, perumusan strategi, implementasi strategi, DMAIC

Abstract

This study aimed to examine the digestibility of fiber, including crude fiber, neutral detergent fiber (NDF), and acid detergent fiber (ADF) digestibility of coconut husk fermented using selected buffalo rumen microbes with varying percentages of inoculum and fermentation periods. The study utilized a completely randomized design (CRD) with a factorial pattern (33) and 3 replications. The first factor was the percentage of inoculum (0%, 2.5%, and 5% mL of inoculum per gram of dry matter of coconut husk), and the second factor was the fermentation period (0, 7, and 14 days). The collected data were analyzed using analysis of variance (ANOVA) and, where applicable, Duncans multiple range test. The results indicated that there was no significant interaction (P0.05) between the different percentages of buffalo rumen fluid as inoculum and the varying fermentation periods on crude fiber and ADF digestibility of coconut husk. However, the percentage of buffalo rumen fluid as inoculum had a significant effect (P0.05) on crude fiber and ADF digestibility, and the fermentation period also significantly influenced (P0.05) ADF digestibility. An interaction between the percentage of buffalo rumen fluid and fermentation period had a significant effect (P0.05) on NDF digestibility. The findings concluded that the percentage of buffalo rumen fluid as inoculum and the fermentation period did not increase crude fiber and ADF digestibility; however, the interaction between 2.5% buffalo rumen fluid inoculum and a 14-day fermentation period resulted in improved NDF digestibility of coconut husk.

Abstract

This study aimed to determine the nitrogen retention in local sheep fed dwarf elephant grass (Pennisetum purpureum cv. Mott) and indigofera (Indigofera zollingeriana). A completely randomized design (CRD) was used, consisting of four treatments with four replications each. The dietary treatments included: T= 100% dwarf elephant grass, T= 95% dwarf elephant grass + 5% indigofera, T2= 90% dwarf elephant grass + 10% indigofera, and T= 85% dwarf elephant grass + 15% indigofera. The parameters measured were dry matter intake (DMI), dry matter digestibility (DMD), nitrogen (N) intake, N retention, and average daily gain (ADG). The results showed that DMI, DMD, N intake, N retention, and ADG were significantly (P0.05) influenced by the dietary treatments. Based on these findings, the combination of 95% dwarf elephant grass and 5% indigofera was the most effective in improving DMI, DMD, N intake, N retention, and ADG in local sheep.
