Abstract
Avian influenza (AI) subtype H5N1 virus is very contagious among domestic poultry such as chicken (Gallus gallus) and potentially infecting humans through direct or indirect contact with the infected animal. In the Surakarta area, Central Java, there are two major poultry markets, Silir poultry market and Jumantono farm. Here, we determined the seroprevalence of the AI virus in chickens sold in both poultry markets. The method was conducted using an explorative experiment by collecting 140 samples of chicken blood serum. The presence of antibodies to the AI virus subtype H5N1 was measured through a standard serological test via hemagglutination-inhibition (HI) assay. The HI assay detected a large antibody difference against AI from samples of both locations; 4.28% from Silir poultry market and 48.57% from Jumantono farm. Because the chickens from the Silir poultry market were not vaccinated, the level of antibody detected indicatesd that some chickens were exposed to the virus through infection. Meanwhile, the high positivity rate in Jumantono farm might reflect the presence of neutralizing antibody, since the chickens from this farm received periodic vaccinations. Continuous quality surveillance in the environment of the poultry market is essential to reduce the impact of AI outbreaks against chickens and humans.
Eimeria piriformis live-attenuated vaccine is successfully lower clinical coccidiosis of rabbits raised in tropic

Abstract
Livestock can sustain expected levels of productivity if the disease is controlled successfully. Rabbit coccidiosis is the major disease-causing high mortality and morbidity. Since no vaccine is available, the eradication is primarily based on careful management combined with medication in feed or water. Chemical coccidiostat is not only raising antibiotic resistance. It also adds environmental contamination since antibiotic is secreted onto land and water. In this report, we attenuate Eimeria piriformis and used it as the vaccine candidate for New Zealand rabbits in Yogyakarta, Indonesia. 90% of rabbits immunized with live attenuated E. piriformis showed no severe signs when challenged with wild type containing 5 x 105 oocyst. The use of live-attenuated E. piriformis is promising as coccidiosis prevention and control program. The strategy would reduce the continuous usage of chemoprophylactic substances in rabbit husbandry and therefore contribute in reducing environmental contamination of antibiotics

Published: November 2021

Abstract
This research was conducted to study the effects of cat whiskers leave juice (Orthosiphon stamineus Benth) (OLJ) on the dressing percentage, giblet, and abdominal fat of broiler chicken. The research used 100 chicks which were reared for five weeks. At the end of the fifth week, 40 chickens were slaughtered as samples. The diets consisted of a commercial ration with 2900 kcal.kg−1 metabolizable energy and 22% protein. The drinking water consisted of different levels of OLJ (0, 10, 20, 30 mL/L). A Completely Randomized Design was used in this research with 4 treatments and 5 replications. Dressing percentage, liver, heart, gizzard, and abdominal fat were observed. The data were analysed by Analysis of variance/ANOVA. The result showed that OLJ significantly (P<0.01) affected live bird’s weight, but not significantly different (P>0.05) for dressing percentage, giblet, and abdominal fat of broiler chicken. On broiler chicken, administration of 10 mL/L OLJ significantly (P<0.01) decreased the live bird’s weight compared to control (0 mL/L OLJ). However, drinking 20 mL/L and 30mL/L cat whiskers juice were not significantly different. The conclusion is that the broiler chicken could tolerate up to 30 mL/L cat whiskers leaves juice.
Application of VECM on livestock production index, carbon dioxide damage, arable land, population growth, and GDP growth in Indonesia

Published: November 2021

Abstract
Environmental effects due to carbon dioxide in Indonesia tend to increase and arable lands are shrinking. These things are accompanied by population and economic growth, making the need for food higher so that the livestock production index increases. After the economic crisis caused by the subprime mortgage, the livestock production index gradually recovered and increased consistently in 2009-2018. However, it turns out that the contribution of the livestock sector to the economy in 2011-2013 was still below the agricultural and plantation sectors. The purpose of this research was to analyze the cointegration and causality relationship of livestock production index, carbon dioxide damage, arable land, population growth, and GDP growth using the VECM method for time series data from 1970-2018. The results show that there was cointegration between variables. The causality test shows that population growth and carbon dioxide damage affect each other. Meanwhile, the livestock production index on population growth has a one-way causality pattern. Arable land on carbon dioxide damage also has a oneway causality pattern. In general, the VECM model shows that there is a long-term relationship between the variables that were used in this research.
Integration of livestock supply chain strategy as part of the creative economy and creative industry in Indonesia: literature review
Authors: Prasetyani D , Ardianto D T , Firdaus A A 
Published: November 2021

AbstractLow production capacity and the traditional farming method that is practiced in Indonesia have resulted in Indonesia dependent on imports to fulfil the demand. Meat, milk, eggs, even skins still can not be fully supplied from national production. Livestock supply chain strategies such as the application of the creative economy and creative industries are needed to overcome the dependency gap on imported raw materials. The challenge in Indonesia is lack of technology & knowledge. This study aimed to determine the role of the creative economy and the creative industry in improving the livestock supply chain in Indonesia. This study used a conceptual method from a literature study. Currently, the creative economy and creative industries are still relatively at the level of SMEs. The recurring problem shows the weak management of technology and knowledge. Based on the literature study result, the creative economy and creative industries can increase the supply of livestock in Indonesia. Hopefully the research on creative economy strategies and creative industries will not only become a trend but also sustainable in the future.

Published: November 2021

Abstract
Poultry industries in Indonesia develop rapidly in line with the increasing demand for poultry meat and eggs. However, fluctuations in availability and the high price of commercial feed bring about a serious problem for traditional farmers. The objective of this study was to evaluate the effect of feeding a diet containing a fermented mixture of water hyacinth leaves (Eichornia crassipes), rice bran, and blood (WRPS) on the production performance and nutrient digestibility of Pekin ducks. This research was conducted for 6 weeks using 100 Pekin ducks (unsex) aged 2 weeks. This study was conducted using a completely randomized design consisting of 4 treatments and 5 replications. The dietary treatments were T0 (control), T1 (30% WRPS), T2 (40% WRPS), and T3 (50% WRPS). At the end of the feeding trial, one duck from each replicate was put in a metabolic cage for digestibility study, adopting the total collection method. Incorporating WRPS in the diet brought significant differences (p<0.05) in feed intake, body weight gain, feed conversion, and digestibility. It can be concluded that the fermented mixture of water hyacinth leaves, rice bran, and protein of slaughtered waste as much as 30% can be used in the diet of Pekin ducks.
Digital marketing as a strategy for fulfilling Eid Al-Adha beef cattle: A case study of start-up companies
Authors: Pramana H P , Hastjarjo S , Sudarmo  
Published: November 2021

Abstract
The demand for beef cattle increases every year ahead of the Eid al-Adha celebration. While the fulfillment of orders in the market is rising, the critical point is that the distribution of beef cattle tends to be uneven between regions. This paper proposes a case study of how the interaction between market and demand fulfillment, in the case of the beef cattle market, can be supported by digital marketing. The focus is how the new company (start-up) creates a marketing chain between regions, West Nusa Tenggara and DKI Jakarta. An in-depth characterization of the marketing chain was carried out through semi-structured interviews. In addition, secondary data uses institutional/private publication data, which is then analyzed descriptively. Using integrated marketing communications (IMC) practices, we explore an enhanced framework for managing communications in the digital world. This research is expected to help fulfill the needs of livestock (beef cattle) to be more optimal, concise, attractive, and evenly distributed so that the social objectives of the celebration of Eid al-Adha are achieved. The study also highlights the utility for organizations to use social media strategically rather than simply as a tactical tool.

Abstract
This study aimed to determine the effect of body weight clustering and betaine supplementation to adequate nutrient diet on the growth performance of quails. Nine hundred seven-day-old quails (Coturnix coturnix japonica) were allotted to a 3×2 factorial completely randomized design. Three bodyweight clusters included Random (21.1±1.2 g), Low (17.9±0.4 g), and High (22.4±0.4 g). Each bodyweight cluster was fed a diet without (0%) and with betaine supplementation (0.14%), resulting in six combination treatments. Each treatment consisted of five replicates of 30 quails. The basal diet was formulated with sufficient protein (22%) and metabolizable energy (2800 kcal/kg). The observed variables included feed intake, body weight, feed conversion, and protein and energy efficiency ratio. The results revealed that there was no interaction between body weight and betaine supplementation on all variables. The High body weight group consumed more feed and produced a higher body weight on 42 days of age than other treatments (p<0.05). However, betaine supplementation did not affect all growth trait variables. In conclusion, betaine supplementation to nutrient adequate diet is not effective in improving growth performance of quails divergently selected based on body weight.

Authors: Tjahjono A , Wijayanti E J , Prayogo D , Wong F T 
Published: November 2021

Abstract
Castellated beams are commonly used in steel construction. This study will focus on castellated beams with circular-shaped openings, which are known as cellular beams. Cost optimization of cellular beams is needed to maintain cost efficiency. The optimization considers the selection of a root beam, the diameter of holes, and the total number of holes in the beam as the variables. Four metaheuristic algorithms are used to optimize the design, namely, the particle swarm optimization (PSO), differential evolution (DE), symbiotic organisms search (SOS), and artificial bee colony (ABC). A four-meter span beam with a 50 kN point live load in the middle of the beam and a 5 kN/m uniformly-distributed dead load are taken as the case study. The results indicate that the SOS algorithm yields the best optimization results in terms of the average, consistency, and convergence behavior with a 30 out of 30 success rates.
The study of shear wall uses in buildings during the architecture design process
Authors: Teddy Livian , Hidayat Husnul , Andriyali A Dessa 
Published: November 2021

Abstract
In Indonesia, an earthquake-prone area, building designs must be earthquake resistant, and using shear walls is one of the ways to make buildings more earthquake resistant. However, determining the requirements and optimal position of shear walls is difficult. Miscalculating in their positioning can cause torsion and other unpredictable behavior. Previous studies were done to know shear walls’ optimal areas and positioning. The first way was trial and error, but this method was ineffective and took a long time. The second way, MATLAB programming, is actually very effective since the needs and orientation of the walls can be determined precisely. Nevertheless, not all structural engineers and architects master the programming language. This study, therefore, proposes relatively simple formulas and procedures to determine the optimal area and positioning of shear walls for architects preliminary design during architecture design process. The accuracy test for the formulas and procedures was carried out using ETABS simulation experiments on 10 building models with various irregular categories. The result showed the formulas and procedures proposed in this study were quite accurate in calculating the needs and position of shear walls. Optimal conditions, furthermore, were quite easy to achieve in symmetrical geometric compositions (1 or 2 axes) while organic or random geometric compositions were quite difficult to achieve. When the use of shear walls achieves optimal condition, the strength and stiffness of a building are increased, and the distribution of its strength and stiffness is relatively even, hence anticipating deformation behavior and reducing building eccentricity.
Modified Partial Capacity Design (M-PCD): achieving partial sidesway mechanism by using two steps design approach
Authors: Tanaya L S , Herryanto H , Pudjisuryadi P 
Published: November 2021

Abstract
Partial Capacity Design (PCD) has been developed by using magnification factor to keep some columns undamaged during major earthquake. By doing so, the structures will experience the partial side sway mechanism which is also stable, instead of the beam sidesway mechanism. However, in some cases, structures designed by PCD method failed to show the partial side sway mechanism since unexpected damages were still occurred at some columns. In this research, modification of PCD method is proposed by using two structural models in the design process. The first model is used to design beams and columns which are allowed to experience plastic damages, while the second model is used to design columns which are intended to remain elastic when the structure is subjected to a target earthquake. Two nominal earthquakes corresponding to Elastic Design Response Spectrum (EDRS) level with seismic modification factors (R) of 8.0 and 1.6 are used in the first and second structural models, respectively. It should be noted that the second model is identical to the first model except that the stiffnesses are reduced for elements to simulate potential plastic damages. This proposed method is applied to symmetrical 6 and 10 storey buildings with seismic load according SNI 1726:2012 and with soil classification of SE in Surabaya city. A Non-linear Static Procedure (NSP) or pushover analysis and Non-linear Dynamic Procedure (NDP) or time history analysis are employed to evaluate the performance of the structure. The evaluation is conducted at three earthquake levels which are nominal earthquake that is used in second model, earthquake corresponding to EDRS level, and maximum considered earthquake (MCER) specified by the code (50% higher than EDRS level). The building performances satisfy the drift criteria in accordance with FEMA 273. However, the partial side sway mechanism was not achieved at NDP analysis at maximum seismic load, MCER.

Abstract
Shear walls modelling as planar or assembly have different assumption in behaviour that will give different responses in forces. Shear wall planar modelling as individual walls which each wall was modelled as a vertical beam. Shear Wall assembly modelling as a combined unit to be represented by one beam element. The application of shear wall assembly is placed in elevator shafts in buildings or stairwell. [1]. In ETABS program, there are two types modelling shear wall are planar walls and wall assemblies. The analysis is based on three types of design section that are Simplified Compression (C) and Tension (T), Uniform Reinforcing and General Reinforcing. The purpose of this study is comparing the planar walls Simplified C and T with planar walls Uniform Reinforcing and wall assemblies Uniform Reinforcing. The conclusion for longitudinal reinforcement are, first, planar walls Simplified C and T is 40 to 96 % larger than wall assemblies, except pier P6 is 28 % smaller, second, planar walls Uniform Reinforcing is larger than 7 to 33 % wall assemblies Uniform Reinforcing, except pier P6 is 39 % smaller, third, the planar walls Simplified C and T, planar walls Uniform Reinforcing transversal reinforcement are 1 to 8 % larger than wall assemblies Uniform Reinforcing, except pier P6 is 51 % smaller.
Review of autonomous self-healing cementitious material
Authors: Susanto S A , Hardjito D , Antoni A 
Published: November 2021

Abstract
Concrete is a well-known versatile material, and its application is very common in most structures. Concrete performance is high in compression but low in tensile strength, this leads to the appearance of microcracks when the structure bears the designed loading. Such microcracks when ignored, leaves the structure vulnerable to attacks such as seepage of water, chlorides, and other materials that lead to a reduction in performance, and extreme cases failure of the structure. Since cracking is inevitable in concrete, new materials with self-healing properties are introduced into the mixture to take advantage of the external materials while making the concrete stronger. This type of concrete is widely researched from 1970 until the present day and is still in ‘proof of concept stages, and very few to no applications of autonomous self-healing concrete in real-world structures. This paper is an attempt to further classify the existing methodologies and find the gaps between researchers. The autonomous healing of concrete in present-day research varies in results; this means that the self-healing methodology requires standardization. Furthermore, self-healing in concrete does not mean maintenance is not required, it implies an easier maintenance method is possible due to the benefits gained through a possibly higher early cost in construction.
