Abstract

ABSTRAK Peningkatan populasi sapi perah merupakan upaya untuk meningkatkan produksi susu, namun di sisi lain peningkatan populasi meningkatkan emisi metana. Pelitian ini bertujuan untuk mengevaluasi bagaimana gambaran efisiensi emisi metana terhadap produksi susu sapi perah di Kabupaten Semarang berdasarkan data populasi dan produksi susu. Emisi metana dihitung menggunakan metode tier 1. Data populasi sapi perah laktasi dan data produksi susu tahun 2015-2020 digunakan untuk menghitung efisiensi emisi metana terhadap produksi. Populasi sapi perah induk laktasi dari tahun 2015-2017 mengalami penurunan sebanyak 452 ekor (4,8%) dibandingkan tahun 2015. Namun, pada tahun 2018-2019 meningkat sebanyak 872 (9,8%) dibandingkan tahun 2017. Emisi metana dari fermentasi enterik dan pengelolaan kotoran ternak tahun mengalami penurunan pada tahun 2015-2017 namun, kembali meningkat pada tahun 2018-2020. Emisi metana tertinggi pada tahun 2019 dan tahun 2020 sedangkan yang terendah pada tahun 2017. Rata-rata emisi metana fermentasi enterik tahun 2015-2020 yaitu 9,9 CO2-e Gg/tahun sedangkan rata-rata emisi metana pengelolaan kotoran ternak 5,0 CO2-e Gg/tahun. Efisiensi emisi terhadap produksi dari tahun 2015-2020 rata-rata 5,6-7. Efisiensi emisi terhadap produksi paling baik yaitu pada tahun 2017 yaitu sebesar 5,4-7, sedangkan yang paling buruk yaitu pada tahun 2016 yaitu sebesar 5,8-7. Dapat disimpulkan bahwa, peningkatan populasi perlu diikuti dengan peningkaan produksi susu supaya emisi yang dihasilkan semakin sedikit untuk memproduksi susu per satuan unitnya. Tahun 2017 merupakan gambaran efisiensi produksi per emisi yang paling baik di Kabupaten Semarang yaitu terjadi peningkatan efisiensi sebesar 6,9%. Kata kunci: efisiensi, emisi metana, produksi susu, sapi perah.The Overview of Methane Emission Efficiency on Dairy Cow Milk Production in Semarang RegencyABSTRACT The increase in the population of dairy cows is in an effort to increase milk production, but on the other hand, the increase in population increases methane emissions. This study aims to evaluate the overview of the efficiency of methane emissions on milk production of dairy cows in Semarang Regency based on population and milk production data. Methane emissions were calculated using the Tier 1 method. Data on the population of lactating dairy cows and data on milk production for 2015-2020 were used to calculate the efficiency of methane emissions on production. The population of lactating dairy cows from 2015-2017 decreased by 452 heads (4.8%) compared to 2015. However, in 2018-2019 it increased by 872 (9.8%) compared to 2017. Methane emissions from enteric fermentation and management of manure decreased in 2015-2017 but increased again in 2018-2020. The highest methane emission was in 2019 and 2020 while the lowest was in 2017. The average enteric fermentation methane emission in 2015-2020 was 9.9 CO2-e Gg/year while the average methane emission from manure management was 5.0 CO2-e Gg/year. The efficiency of emissions to production from 2015-2020 on average 5.6-7. The best emission efficiency towards production is in 2017 which is 5.4-7, while the worst is in 2016 which is 5.8-7. It can be concluded that an increase in population needs to be followed by an increase in milk production so that fewer emissions are produced to produce milk per unit. The year 2017 is the best overview of production efficiency per emission in Semarang Regency, which is an increase in efficiency of 6.9%.Keywords: efficiency, methane emissions, milk production, dairy cows

Abstract

This study aimed to evaluate feed protein utilization and nitrogen emission of young and mature Kejobong goats fed different concentrations of concentrate and forage. Sixteen heads of male Kejobong goats consisted of eight heads young goats (5 months old) and eight heads mature goats (9 months old) with initial body weight (BW) of 14 ± 1.46 kg, and 22.3 ± 1.99 kg, respectively were arranged in a nested design. All goats were fed with two different rations of concentrate and forage (C30 = 30% concentrate: 70% forage and C70 = 70% concentrate: 30% forage). The data were analyzed using ANOVA procedure. This study showed that the average daily gain (ADG) did not differ (p>0.05) in both ages, but it differed (p<0.05) in concentrate levels. The ADG of goats fed C70 was significantly higher (p<0.05) than those of goats fed C30 in both ages. The digestible crude protein (DCP) of young and mature goats was similar (p>0.05), while there was a significantly difference (p<0.05) between the treatments. There were no effects of different ages of goats and concentrate levels on feed conversion ratio (FCR) (p>0.05). The different ages of goats and concentrate levels affected N retention (g/day) and total N2O emission (g/day). It was concluded that ADG, DCP and FCR did not differ in mature and young Kejobong goats, while young goats had less N2O emissions than mature goats. Goats fed 70% of concentrate improved their ADG, DCP, N retention (g/day) and produced less N2O emission.

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi daun bawang merah terhadap performan domba. Metode Penelitian ini menggunakan RAL (Rancangan Acak Lengkap) dengan 5 perlakuan dan 3 kali ulangan. Penelitian ini menggunakan 15 ekor domba yang dibagi menjadi lima perlakuan dengan T0 (tanpa daun bawang merah); T1 (Pakan basal + 300 g daun bawang merah); T2 (Pakan basal + 600 g daun bawang merah); T3 (Pakan basal + 900 g daun bawang merah); T4 (Pakan basal + 1200 g daun bawang merah). Parameter yang diamati adalah pertambahan bobot badan, konsumsi pakan, dan rasio konversi pakan. Hasil penelitian menunjukkan bahwa suplementasi Daun bawang merah (Allium ascalonicum) T4 berpengaruh nyata (P<0,05) terhadap peningkatan bobot badan, konsumsi pakan, dan rasio konversi pakan. Berdasarkan penelitian ini dapat disimpulkan bahwa suplementasi daun bawang merah sebanyak 1200 g dalam ransum basal mampu memberikan performa domba yang lebih baik.Effect of shallot (Allium ascalonicum) leaf supplementation in basal ration on lamb performanceABSTRACT. This study aims to determine the effect of shallot leaf supplementation to lamb performance. This study method used a Completely Randomized Design (CRD) with 5 preparations and 3 replications. This study used 15 lamb’s which were divided into five treatments with T0 (without shallot leaf); T1 (Basal feed + 300 g of shallot leaf as feed); T2 (Basal feed + 600 g of shallot leaf as feed); T3 (Basal feed + 900 g of shallot leaf as feed); T4 (Basal feed + 1200 g shallot leaf as feed). Parameters observed were liveweight gain, feed consumption, and feed conversion ratio ratio. The results showed that the addition of shallot leaf (Allium ascalonicum) T4 had a significant effect (P<0.05) on the increase in liveweight gain, feed consumption, and feed conversion ratio. The shallot leaf supplementation of 1200 g as feed gave better lamb performance. This study concluded that the supplementation of 1200 g of shallot leaf in the basal ration was able to provide better lamb performance.Keyword: Feed consumption, Feed conversion ratio, shallot leaf, Lamb, and Liveweight gain
