Published: March 2022

AbstractBuffalo is a ruminant animal that has the ability to digest the high content of crude fiber feed. Furthermore, agricultural waste such as rice straw is a common buffalo feed in Indonesia, with high crude fiber content, helping farmers manage their agricultural waste. Despite the high availability of rice straw, buffalo population decreases in some areas in Indonesia. This study further aims to determine the reproductive performance of female buffalo in smallholder farms in Karanganyar Regency, Central Java, Indonesia. The research was conducted in April-August 2021 in Colomadu, Kerjo, Jumantono, Kebakkramat, and Karanganyar Districts. A survey method was used, whereby samples were collected through the census with 9 respondents with female buffalo that had given birth at least 2 times. The data obtained were then analyzed using descriptive and quantitative analysis in the form of mean and standard deviation. As a result, the value of service per conception (s/c), gestational length and days open (DO), as well as calving interval (CI) were 1.33±0.5, 297.7±38.8 days, 120.9±30.3 days 418, and 56±35.6 days, respectively. Therefore, it is concluded that the reproductive performance of female buffalo (Bubalus bubalis) on smallholder farms in Karanganyar Regency, Central Java, Indonesia is in good condition.

Abstract
Processed animal protein is typically preferred over fresh livestock products for consumption because it is more stable and environmentally friendly when stored over a long period. Therefore, this preliminary study aimed to determine consumer preferences for processed meat products based on consumer choice brand priorities. The consumers were asked to select three preferred processed meat product brands, including sausage, corned beef, meatballs, nuggets, and meat floss, as well as the primary reason for their selection. The study included 450 meat consumers who were selected by purposive sampling. Subsequently, descriptive statistics and Chi-Square analysis were used to determine the preferences among the three product selections. The results showed that the three main preferences of consumers in selecting processed meat products were based on taste, quality, and price in that order. Consumers preferred and selected products with superior taste and quality but were more likely to consider price as the priority decreased. Therefore, the ability to understand consumer preferences plays a key role in developing a sustainable product since cost is not considered a primary concern.

Abstract
Kenteng Village has the potential for beef development due to its high cattle population. However, cow dung waste produced by farmers has not been optimally used, hence its additional benefits have not contributed to the community’s economy. This has also led to environmental pollution due to improper waste management. Therefore, empowerment efforts are needed to improve farmers’ knowledge and skills in managing livestock manure to increase their income and create environmentally friendly conditions through training activities on the manufacture of organic bio-slurry fertilizer as well as maintenance and construction of biogas installations using fixed dome plant technology. Furthermore, the training was held from August 15-September 26, 2021, in Kenteng Village, Nogosari District, Boyolali Regency. The empowerment program is implemented through Focus Group Discussion (FGD), extension, training, demonstration plots on the production technology of organic fertilizer and biogas for fuel production. Materials used in producing the fertilizer include slurry obtained from biogas waste and agricultural lime/dolomite. The dome plant constructed contains a digester with 6 main parts, namely inlet, reactor, gas reservoir, outlet, gas transport system and compost pits for degassed animal manure/bio-slurry. The training result shows an increase in farmers’ knowledge and skills on the application of bio-slurry organic fertilizer production technology and the construction of biogas installations as a fuel producer. There was also an increase in their income, which improved their standard of living. Conclusively, the community in Kenteng Village was more empowered by the existence of a biogas installation development program.

Abstract
The empowerment of smallholders is part of sustainable agricultural development to increase production. This study aims to identify the characteristics of beef cattle farmers and social capital, and also to determine the effect of social capital on the empowerment of smallholder beef cattle farmers in Sragen Regency. The study was conducted in June 2021 in Plupuh District by using purposive sampling method to determine the location and the respondents. The number of respondents was 100 smallholders who had at least 1 year of experience in raising beef cattle. Data were collected through direct interviews with the smallholders and were analyzed descriptively by using multiple linear regression analysis together with the F test and R2 test in order to determine the effect of social capital on empowerment. The results showed that most of the respondents had a low level of education, and the majority of the respondents’ occupations were laborers. It also showed that the respondents had a side job as a smallholder and the status of livestock ownership was their own. Subsequently, the regression analysis obtained Y = 4.517 – 0.525X1 + 0.617X2 +0.153X3 - 0.186X4 + 0.550X5 and it is interpreted that all social capital variables consisting of willingness, openness, encouragement, activeness, and participation simultaneously affect the empowerment of beef cattle smallholders. In the coefficient of determination test (R2), the results obtained is 0.321 which implied that the social capital variable had an influence of only 32.1% on the empowerment of beef cattle smallholders, while the remaining 67.9% was influenced by other variables not included in this study. Therefore, it was concluded that social capital only had an effect of 32.1% on the empowerment of livestock smallholders.

Authors: Gunawan Aam 
Published: March 2022

Abstract
Black soldier fly (BSF) maggot is a biological agent that can solve the problem of converting organic waste into biomass for poultry feed as well as fertilizers. Although live maggot supplementation in ducks functions as cheap feeds, it raises significant concerns because it can affect egg quality, changing the taste and odor. Therefore, this study aims to determine the organoleptic quality of duck eggs fed with live maggot (Hermetia illucens) using 120 Alabio ducks (Anas platyrhynchos) placed in postal cages. It was conducted using a completely randomized design with a 2×2 factorial pattern to investigate the effect of two independent factors, namely protein level at 15% and 21%, as well as the concentration of live maggot supplementation given at 0 and 40 g/bird/day. The texture, flavor, and odor were tested using 67 moderately trained panelists, while the yolk color was determined using an egg yolk color fan, then the data obtained were analyzed for variance. The results showed that the protein level of the diet significantly affected the yolk’s texture and odor, but not the flavor and color. Furthermore, an interaction occurred between the protein level of the diet with the live maggot supplementation on the texture. Based on the results, Alabio ducks fed with a high protein diet namely 21% plus 40 g/bird/day live maggots produced eggs with a soft texture, good flavor, fishy odor, and the highest average color score of 8.69 compared to other treatment combinations.
Determination of tetracycline residues in dairy milk powder and fresh dairy milk by HPLC method
Authors: Widiastuti R , Anastasia Y 
Published: March 2022

Abstract
Tetracycline residues are group of antibiotics found in animal products such as dairy milk. In this study, the occurrence of tetracycline residues in 45 dairy milk powder and 24 fresh dairy milk samples have been investigated. Tetracycline residue were extracted from milk samples using McIlvine buffer and purified with a solid phase extraction (SPE) C18 column. Residues were detected through HPLC-PDA at wavelengths of 355 and 368 nm. Three forms of tetracyclines were discovered in the 45 milk powder samples, namely; oxytetracycline (31.75 ng/g), tetracycline (28.02 ng/g) and chlortetracycline (10.55 ng/g). The results of 24 fresh dairy milk samples, on the other hand, revealed that only one form of tetracycline (i.e., oxytetracycline) was detected with concentrations ranging from 6.67 to 10.19 ng/g. Although the low incidence and concentration levels of tetracycline contamination in all samples analysed were not alarming, regular monitoring is recommended to avoid any negative public health consequences.

Published: March 2022

Abstract
The continuous use of antibiotics and inappropriate doses in broilers results in antibiotic residues, thus leading to health problems. An example of LAB that can be used as an antibiotic alternative is the Pediococcus pentosaceus isolate Strain N6. Therefore, this study aims to determine the effectiveness of metabolic antimicrobials produced by the isolates of Pediococcus pentosaceus Strain N6. The method used was an in vitro test consisting of several phases including the test of supernatant antimicrobial activity with pathogenic bacteria (Salmonella typhimurium and E. coli); the test for acidic conditions, bile salts, tolerance to gastric juice, sensitivity to antibiotics, and proteolytic enzymes. The results showed that the antimicrobial activity of the supernatant against Salmonella typhimurium and E. coli bacteria was 15 mm and 18 mm, respectively. This activity is found to be tolerant to acidic conditions, such as pH 2, at 0.5% bile salt concentration, as well as gastric juice, and also sensitive to penicillin, streptomycin, and proteolytic enzymes. Furthermore, the metabolism of an isolate is a useful alternative for antibiotics in chickens.

Published: March 2022

Abstract
Climate change has been proven to increase the vectorial capacity of disease carrying-arthropods, including Aedes aegypti, a crucial vector of several arthropod-borne viral diseases that affect humans all over the world. The control of mosquitoes is mostly performed through the use of chemical based-insecticides. However, the viability of this method has become a topic of debate, for instance, the continuous use of these chemicals tends to cause insecticide resistance. This study, therefore, aims to investigate the resistance of Aedes aegypti from South Sumatra to several insecticides. Several A. aegypti eggs were collected and reared until they became adult mosquitoes. Subsequently, the mosquitoes were subjected to insecticide susceptibility tests, using six different insecticides: 5% malathion, 0.05% deltamethrin, 0.75% permethrin, 0.05% lambda-cyhalothrin, 0.1% bendiocarb, and 0.15% cyfluthrin, based on the WHO protocol, for 24 hours of exposure. The results showed that the average mortality rate for 5% malathion, 0.05% deltamethrin, 0.75% permethrin, 0.05% lambda-cyhalothrin, 0.1% bendiocarb, and 0.15% cyfluthrin were 100%, 30.63%, 26.06%, 51%, 64.16% and 75.87%, respectively. Therefore, Aedes aegypti were concluded to be highly sensitive to 5% malathion.

Abstract
This paper outlines the prerequisites and process of establishing of a community-based energy centre for sustainable agriculture practices in a rural village in the Vietnamese Mekong Delta. The centre was constructed by community consensus building and consisted of two main components including a community house and a community-biogas production system. The community house acts as a place where local people organize community activities such as traditional festivals and the production local products for local markets as well as community tourism. The community-biogas production system consists of a 41,6 m3 large biogas digester. The digester utilizes collected bio-degraded organic wastes from the local households and waste from animal husbandry as well as additional available green biomass such as water hyacinth. Methane produced will be used for cooking activities at the centre and delivered to the households in the community. Local people have contributed their own labours to build and manage the community-energy centre. Capacity building for the community is supported by experts of universities in both Vietnam and Japan. The community further intents to self-organize themselves to earn benefits through sustainable agricultural production such as planting organic vegetable and fruit trees, animal and fish raising, etc. This model is the first step in promoting the village as the “the most beautiful village” to clean up and promote environmental and sustainable technologies in the village. Furthermore, it is also a good option for inclusion in upgrading criteria for new rural development issued by Vietnamese government.

Authors: Gong Cong , Hu Changjuan 
Published: March 2022

Abstract
Maintaining and restoring urban biodiversity is one of the basic functions of green infrastructure. Starting from the ecological problems of community public open space and the insufficiency of traditional planning methods, the biodiversity of green infrastructure attempts to be integrated into public open space planning in community-scale. After discussing the research on the combination of community public open space and green infrastructure based on biodiversity, ‘the interconnections between green infrastructures’ is the key to achieving both benefits at the same time. Finally, taking Nanjing Xinjiekou Street in China as an example, the renewal planning method of community public open space on the priority of biodiversity is elaborated and corresponding suggestions are put forward. In a word, the reasonable planning and layout of community green infrastructure based on biodiversity can make up for the disadvantages of traditional planning and renewal methods of public open space to a certain extent, solve the ecological and social problems of public open space, and realize the symbiosis of people and nature in community.
Improving the Performance of Baker’s Yeast-powered MFCs by Adding Dehydrogenase Enzymes to Oxidize Yeast-produced Ethanol

Published: March 2022

Abstract
This study focuses on theoretically and experimentally enhancing the performance of a baker’s yeast-powered microbial fuel cell (MFC) by hybridizing the MFC and EFC (enzymatic fuel cells) technologies. To improve the power density of the MFC, commercially available alcohol and aldehyde dehydrogenase enzymes (ADHE) have been added to the anode chamber to oxidize ethanol, which is produced by Baker’s yeast (BKY) during the metabolic process, to acetic acid. This oxidation process contributes more power output for the MFC. BKY biofilm was formed in porous 3D activated carbon paper to make the anode. The combination of using the biofilm anode and ADHE for electricity generation by the MFC enabled about 19% improvement in the maximum power density if compared with the MFC without using ADHE. Also, aerobic and anaerobic culture conditions were investigated. The result showed that under the anaerobic culture condition, the MFC generated about 22% higher maximum power density than that of the aerobic condition. These results imply that the addition of ADHE can take full advantage of BKY-produced ethanol to boost overall BKY-powered MFC performance.

Abstract
The crisis of fossil fuel exhaustion and environmental pollution promotes the employment of distribution generators in distribution systems. The intermittent and random nature of distributed generators may bring threaten to the reliability and stability of the power grid. To improve the N-1 evaluation schema for distribution grid with DGs, an evaluation index system and comprehensive evaluation method for distribution system are proposed in this paper. Security, economy, quality and development coordination of system are analysed and used as the evaluation indexes. An evaluation framework is implemented with an analytic hierarchy process and a gray relational analysis method. The proposed index and framework were implemented tested with a modified distribution system on the CloudPSS platform. Multiple optimization objects of planning solutions for the distribution system were evaluated by the proposed frameworks. The best grid connection schema were generated based on the evaluation results. The test results demonstrate the feasibility of the proposed index system and framework.
