This study was to determine the carrying capacity of palm oil plantation and oil palm industry waste could be used as beef cattle feed in West Sumatra. This study used a desk study method, it was the activity that searched secondary data such as the results of other relevant studies, official documents and other important records in several government agencies and other relevant institutions. The analysis showed people carrying capacity of palm oil plantations folk in West Sumatra with the utilization of forage, leaves no stick and palm frond as cattle feed as a whole can accommodate about 390 913 head of cattle. While carrying capacity of byproduct of palm oil processing wastes amounted to 465 812 head of cattle. Overall, therefore, the palm oil plantation folk, the state and the private sector is able to provide beef cattle feed to 856 725 head of cattle. It concluded that beef cattle still have a chancethe to be developed by use oil palm plantation and byproducts as a substitute for forages.Key words: oil palm plantation, carrying capacity, oil palm industry waste, beef cattle feed

Abstract. A unified regional air-quality modelling system (AURAMS) was used to investigate the effects of reductions in ammonia emissions on regional air quality, with a focus on particulate-matter formation. Three simulations of one-year duration were performed for a North American domain: (1) a base-case simulation using 2002 Canadian and US national emissions inventories augmented by a more detailed Canadian emissions inventory for agricultural ammonia; (2) a 30% North-American-wide reduction in agricultural ammonia emissions; and (3) a 50% reduction in Canadian beef-cattle ammonia emissions. The simulations show that a 30% continent-wide reduction in agricultural ammonia emissions lead to reductions in median hourly PM2.5 mass of <1 μg m−3 on an annual basis. The atmospheric response to these emission reductions displays marked seasonal variations, and on even shorter time scales, the impacts of the emissions reductions are highly episodic: 95th-percentile hourly PM2.5 mass decreases can be up to a factor of six larger than the median values. A key finding of the modelling work is the linkage between gas and aqueous chemistry and transport; reductions in ammonia emissions affect gaseous ammonia concentrations close to the emissions site, but substantial impacts on particulate matter and atmospheric deposition often occur at considerable distances downwind, with particle nitrate being the main vector of ammonia/um transport. Ammonia emissions reductions therefore have trans-boundary consequences downwind. Calculations of critical-load exceedances for sensitive ecosystems in Canada suggest that ammonia emission reductions will have a minimal impact on current ecosystem acidification within Canada, but may have a substantial impact on future ecosystem acidification. The 50% Canadian beef-cattle ammonia emissions reduction scenario was used to examine model sensitivity to uncertainties in the new Canadian agricultural ammonia emissions inventory, and the simulation results suggest that further work is needed to improve the emissions inventory for this particular sector. It should be noted that the model in its current form neglects coarse mode base cation chemistry, so the predicted effects of ammonia emissions reductions shown here should be considered upper limits.

Sentra Rakyat Rakyat (SPR) is a collection of cattle breeders in the Subang Regency area. SPR aims to raise beef cattle and provide ruminant feed. Ruminant feed made from corn hump waste. The disc mill machine is used in the process of destroying corn lumps into flour, flour from the results of this corn hump will be combined with other components to form a ruminant feed for cattle feed. The process of making feed is disrupted because the disc mill machine is damaged. This study aims to detect damage to the engine and clasification maintenance of disc mill machines using the Inspection, Medium Repair, Small Repair, and Overhaul (ISMO) methods. The method used in data collection is in the form of interviews and observations. Data is analyzed qualitatively description. The results of this study are (1) machine damage, namely the disc mill cutting blade allowance caused by the destruction of the engine shaft bearing; (2) More maintenance is needed on filter sections, cutting blades, crankshafts, v-belts and bearings.

The research aimed to examine the effect of red dragon fruit skin and guava leaves supplemented into beef cattle feed on the concentration of partial VFA and methane gas production. The in vitro study was conducted in a completely randomized design (CRD) with 3 treatments, namely P0: 50 % concentrate + 50 % ammoniated straw (Control), P1: 50 % concentrate + 50 % ammoniated straw + 5 % red dragon fruit skin flour, and P2: 50 % concentrate + 50 % ammonia straw + 5 % red dragon fruit  skin flour + 2.5 % guava leaf flour. The concentrate consisted of 2 parts of rice bran and 1 part of coconut meal. The ratio of concentrat and ammoniated rice straw was 50:50. Each treatment was repeated 6 times. The results showed that the concentration of acetic acid, butyrate and methane gas decreased while the concentration of propionate increased with the addition of red dragon fruit and guava leaves. The research concluded that the addition of 5 % red dragon fruit skin flour combined with 2.5 % guava leaves flour in beef cattle feed could further reduce the concentration of acetic acid, butyric acid and the production of methane gas, but increase the concentration of propionic acid. It is suggested that defaunated agents of red dragon fruit skin and guava leaves could reduce the production of methane gas in the rumen of beef cattle.

Tujuan diseminasi teknologi pembuatan haylage plus melalui kegiatan pengabdian kepada masyarakat ini adalah untuk meningkatkan pengetahuan, keterampilan dan merubah sikap anggota kelompok tani agar mampu mengolah dan menyimpan bahan pakan ternak yang melimpah pada musim hujan (panen) sebagai solusi untuk mengatasi kesulitan penyediaan pakan sapi potong yang terbatas pada musim kemarau. Metode diseminasi yang digunakan untuk memecahkan masalah tersebut adalah kombinasi metode penyuluhan tatap muka langsung sesuai dengan protokol kesehatan Covid-19 dengan gelar teknologi (showcase technology). Berdasarkan hasil kajian ini sebanyak 28,69% anggota kelompok tani yang pernah mendengar teknologi pembuatan haylage plus dari jerami padi dan hanya 13,79% yang sudah mengikuti pelatihan pembuatan haylage. Berdasarkan hasil kegitan, dapat disimpulkan bahwa tingkat pengetahuan, keterampilan dan sikap anggota kelompok tani terhadap teknologi pembuatan haylage plus masih rendah, sehingga masih perlu ditingkatkan dalam rangka peningkatan kapasitas petani-peternak. Dissemination of Haylage Plus Production Technology to Overcome Difficulties in Feeding Beef Cattle in the Dry Season Abstract The purpose of disseminating the technology for making haylage plus through community service activities is to increase knowledge, skills and change the attitude of farmer group members so that they are able to process and store abundant animal feed ingredients during the rainy season (harvesting) as a solution to overcome difficulties in providing beef cattle feed. limited to the dry season. The dissemination method used to solve this problem is a combination of face-to-face counseling methods in accordance with the Covid-19 health protocol with a technology title (showcase technology). Based on the results of this study, 28.69% of farmer group members had heard of the technology of making haylage plus from rice straw and only 13.79% had attended training on making haylage. Based on the results of the activity, it can be concluded that the level of knowledge, skills and attitudes of farmer group members towards the technology of making haylage plus is still low, so it still needs to be improved in order to increase the capacity of farmers and breeders.

ABSTRACT Exploring compositional and functional characteristics of the rumen microbiome can improve the understanding of its role in rumen function and cattle feed efficiency. In this study, we applied metatranscriptomics to characterize the active rumen microbiomes of beef cattle with different feed efficiencies (efficient, n = 10; inefficient, n = 10) using total RNA sequencing. Active bacterial and archaeal compositions were estimated based on 16S rRNAs, and active microbial metabolic functions including carbohydrate-active enzymes (CAZymes) were assessed based on mRNAs from the same metatranscriptomic data sets. In total, six bacterial phyla (Proteobacteria, Firmicutes, Bacteroidetes, Spirochaetes, Cyanobacteria, and Synergistetes), eight bacterial families (Succinivibrionaceae, Prevotellaceae, Ruminococcaceae, Lachnospiraceae, Veillonellaceae, Spirochaetaceae, Dethiosulfovibrionaceae, and Mogibacteriaceae), four archaeal clades (Methanomassiliicoccales, Methanobrevibacter ruminantium, Methanobrevibacter gottschalkii, and Methanosphaera), 112 metabolic pathways, and 126 CAZymes were identified as core components of the active rumen microbiome. As determined by comparative analysis, three bacterial families (Lachnospiraceae, Lactobacillaceae, and Veillonellaceae) tended to be more abundant in low-feed-efficiency (inefficient) animals (P < 0.10), and one archaeal taxon (Methanomassiliicoccales) tended to be more abundant in high-feed-efficiency (efficient) cattle (P < 0.10). Meanwhile, 32 microbial metabolic pathways and 12 CAZymes were differentially abundant (linear discriminant analysis score of >2 with a P value of <0.05) between two groups. Among them, 30 metabolic pathways and 11 CAZymes were more abundant in the rumen of inefficient cattle, while 2 metabolic pathways and 1 CAZyme were more abundant in efficient animals. These findings suggest that the rumen microbiomes of inefficient cattle have more diverse activities than those of efficient cattle, which may be related to the host feed efficiency variation. IMPORTANCE This study applied total RNA-based metatranscriptomics and showed the linkage between the active rumen microbiome and feed efficiency (residual feed intake) in beef cattle. The data generated from the current study provide fundamental information on active rumen microbiome at both compositional and functional levels, which serve as a foundation to study rumen function and its role in cattle feed efficiency. The findings that the active rumen microbiome may contribute to variations in feed efficiency of beef cattle highlight the possibility of enhancing nutrient utilization and improve cattle feed efficiency through modification of rumen microbial functions.
