FACTORS AFFECTING ONLINE IMPULSE BUYING OF CONSUMERS IN HUE CITY
Authors: Thuong Nguyen Uyen
Published: September 2021

Abstract: this study investigates the influence of independent variables, including scarcity, serendipity and trust on online impulse buying. Besides, the paper examines the moderation role of two variables (stimulating shopping and relaxation shopping) in the interaction effects between those independent variables on online impulse buying. Data are collected from a sample of 209 consumers in Hue city. Structural equation is used to test the hypothesized relationships. The results suggest that while serendipity is significantly positive impacts on online impulse purchasing, scarcity has a significant negative influence on that one. Trust impacts on online buying as proved in some previous studies, but it has an insignificant influence in the context of impulsively online purchasing. Furthermore, stimulating shopping moderate the interaction effect between independent variables (scarcity and serendipity) on online impulse buying. However, relaxation shopping is not significant with moderation effect. By examining different type of drivers, this paper enriches knowledge on online impulse buying and suggest some implications for online retail manager and online trading platforms to attract more consumers and encourage more unplanned consumption. Keywords: Online impulse buying, Scarcity, Serendipity, Stimulating shopping, Relaxation shopping

Authors: Cuong Pham , Đuc Ngo Tung , Duong Đang Thai , Phuong Nguyen Thi Thuy
Published: September 2021

This study assessed the active effects of inter-planting Coffea arabica and Machilus odoratissima Nees, planted over seven years in small-scale farms in Huong Hoa district, Quang Tri province, Vietnam; purpose to evaluate the effectiveness of inter-planting farm of Coffea arabica and Machilus odoratissima in the study site. The results show that the environmental conditions for growing and developing the coffee trees have been improved in the area of mix-planting Coffee and Machilus. The coffee productivity, as a result, has also been increased. In comparison with the living condition at the monoculture farms, wind speed was reduced to 1.67ms-1, soil moisture was increased by 5.1% and soil temperature was decreased by 3.60C at the inter-planting farms. The coffee productivity correspondingly increased by approximately 7.5%. In addition, the value of Machilus products contributed to economic efficiency and economically ensured the sustainability of coffee farms. It also shows that the harvesting Machilus products after seven years of planting contributed over 716.52 USD/ha to the farmer incomes. This could be considered as an economic support to the farmers to maintain the coffee plantation in hash weather conditions or in uncertain prices of productions.

This study focuses on building a regression model in the series of land pricing for frontages and alleys in the C zone of Nam Hoi An project, Thang Binh district, Quang Nam province. The research applied data collection method, data processing method, regression analysis method to build a model of mass land valuation. The results of this study show that the location of the facade in the C zone of ​​Nam Hoi An project is affected by various factors such as security, plot width, plot shape, distance to Hoi An city, traffic congestion, land use type, and road boundary. Meanwhile, the unit price of land in the alley is influenced by factors such as security, alley level, plot shape, distance to Hoi An city, road structure, traffic congestion and alley location. The biggest factor affecting frontage land price is the type of land use with regression coefficient BLAND_USE_TYPE = 14,199. In terms of unit price of alley land, that is the type of alley with regression coefficient BALLEY_LOCATION = 10,772. The results of verification of the accuracy of the land unit price from the regression model to the compensation land unit price have a negligible difference, which is completely consistent with the requirement of determining the price level close to the market price. The results of this study show the practical applicability of mass appraisal for land valuation using a regression model in land acquisition and financial management of land.

EVALUATING A CONCEPTUAL FRAMEWORK FOR TEACHER EDUCATION QUALITY
Authors: Nguyen Chau Hong Phuoc , Zimmerman Aaron Samuel
Published: September 2021

It is critical for teacher educators and scholars of teacher education to think carefully about the conceptual framework that they use to evaluate teacher education programs. Without a strong conceptual framework, it may be difficult for teacher educators to evaluate whether or not they are operating within a strong program. Thus, we frame this article as an opportunity to present one particular pre-existing framework in the research literature that can be used to conceptualize teacher education quality. We then present some evidence that supports and challenges this framework. In other words, the purpose of this study is to evaluate the conceptual framework for teacher education quality proposed by Hsieh, Law, Shy, Wang, Hsieh, and Tang (2011). In our attempt to create a supplementary evaluation of this conceptual framework, we test a statistical model using a different large international database – Teaching and Learning International Survey (TALIS) 2013 (OECD, 2014). Specifically, we examine the effects of preparedness for content knowledge (CK), pedagogical content knowledge (PCK), and field-based practice on teachers’ later performance satisfaction using multiple linear regression analysis. Our findings suggest that teachers who are more prepared for PCK and classroom practice (through field/clinical experience) during their teacher education program tend to be more satisfied with their teaching performance. However, our findings also suggest that becoming prepared in one’s CK during teacher preparation does not, according to the respondents, have a significant impact on their satisfaction with their teaching performance. Findings of this study have implications for practice and future research.

Sleepy and Anxious: Sleep and State/Trait Anxiety and Anxiety Disorders in Adolescents and Young Adults: A Literature Review
Authors: Fayad Petra , Hussein Marwa , Hussein Safa
Published: September 2021

Introduction: Sleep deprivation is a growing global concern, especially in adolescents and younger adults. Specifically, research on the loss of sleep has shown various negative consequences in neurobiological and cognitive functions. Sleep disturbances and mental health disorders have been linked, with sleep disturbances being a symptom of/risk factor for various mental health disorders. However, the relationship between sleep and anxiety remains unclear. The purpose of this review is to investigate the relationship between sleep deprivation and anxiety, namely, its role in state anxiety, trait anxiety, and the formation of anxiety disorders in adolescents and younger adults.
Methods: Primary sources of literature were found through the PubMed and Web of Science databases. Articles investigating the relationship between sleep deprivation, state/trait anxiety and anxiety disorders from within the last two decades were chosen and reviewed.
Results: The literature shows that acute sleep deprivation is linked to increased state anxiety with adolescents being disproportionately vulnerable to the consequences of a lack of quality sleep. Studies show that individuals with higher trait anxiety have poorer sleep quality which may negatively affect emotional processing. The exact nature of the relationship between sleep deprivation and anxiety disorder development is mixed, but the available literature suggests that the relationship is reciprocal.
Discussion: Although there has been an established link between anxiety and sleep deprivation, the mechanisms through which these occur need to be further understood. Findings suggest that sleep quality is affected by a change in the HPA-axis, which can increase cortisol production, a change that has been associated with poorer processing speed. It was also found that adolescents, especially early adolescents, are more vulnerable to the emotional consequences of sleep deprivation than adults are. An expansion of the current literature is required to understand the relationship between sleep and anxiety disorders.
Conclusion: More research in this field for younger populations is required to develop effective preventative measures and treatments for anxiety. Future studies should also consider a multiple disciplinary approach from social and developmental research to fully understand the factors that affect sleep in adolescents and its relationship to anxiety and anxiety disorders.
case for an inequalities perspective in child protection
Authors: Keddell Emily
Published: September 2021

The year 2019 represented a watershed moment for Aotearoa New Zealand’s child welfare system, as a public spotlight was shone on systemic ethnic inequities during ongoing legislative changes aimed at centering Te Tiriti o Waitangi and whänau, hapü, and iwi considerations in policy and practice. In the midst of this dialogue, Victoria University of Wellington’s School of Government hosted the “Children, Families, and the State”– a seminar series focused on the historical, current, and future role of the state in the lives of families and children. The seminars, and the discussion it generated, was due to the calls to action from speakers across the system, including leadership at Oranga Tamariki, within the family court, non-profit providers, commissioners and advocates, and academics.

The four brief essays in this edition of Policy Quarterly capture viewpoints from several of the seminar speakers. Despite their different perspectives, common threads unite them. A greater recognition of the structural causes of the historical and current patterns of ethnic inequities in child welfare system contact, a commitment to whänau, hapü, and iwi-centred policy, practice, and partnership, the authors argue, are vital for a more just and empowering system.

In this essay, Emily Keddell reflects on how a lack of an inequalities perspective in policymaking has shaped New Zealand’s unequal child welfare system, and the ways in which this perspective can drive down the number of children who enter the system in the future.

Downsizing property among the older generation
Authors: Mclaughlan Richard
Published: September 2021

New Zealand experiences widespread intergenerational housing inequalities. Millennials are far less likely than previous cohorts to access affordable housing and to own property. Large dwellings which are often more suited to young and expanding families are arguably underutilised by the older generation. Retirees are living longer and often stay in homes that they have lived in for most of their lives. This is exacerbated by distortions in our tax system which leave owner-occupied housing free from a capital gains tax. One way to phase out this generational discrepancy is motivating older generations to move to smaller homes towards the end of their life cycle. This would free up larger properties for first home buyers and ensure that retirees live in more suitable dwellings.
What is a vested interest?
Authors: Duncan Grant , Chapple Simon
Published: September 2021

The term ‘vested interest’ is often used with a negative connotation, with regard to powerful and wealthy firms or groups who exploit their insider position or block policy changes that others believe would benefit the social interest, the latter potentially including future generations. But the term vested interests also covers members of the public who have rights to participate in public debate. So, how should we understand ‘vested interests’ for the purpose of improving and democratising policymaking processes?
Regulatory Capture in Product Markets and the Power of Business Interests
Authors: Bertram Geoff
Published: September 2021

This article explains pervasive regulatory failure, lagging productivity, and the corporate capture of policy and policymakers as possibly unintended, but not unpredictable, outcomes of the New Zealand Treasury’s radical adoption during the 1980s of public choice and Chicago school doctrines. With deregulation and a limited role of government written into statutes and embodied in regulatory practice, the pathologies identified and described by Buchanan, Tullock, Stigler and their collaborators became more, rather than less, prevalent in the New Zealand regulatory landscape. Privatisation opened the way for looting; the Commerce Act and new regulatory guidelines enabled rather than blocked anticompetitive practices and monopolistic renttaking; relaxed oversight meant that foreign direct investment became more extractive and less productive. From relatively inclusive politics and strong regulatory enforcement, New Zealand shifted towards more extractive institutions and weaker regulation. As a result, market power is exercised by the current business and financial elite in ways that have worsened wealth and income distributions, imposed deadweight burdens (both static and dynamic) on the economy, and now confront policymakers with roadblocks to achieving more inclusive institutions and pursuing a ‘wellbeing’ agenda.
Vested Interests in Big Agriculture
Authors: Joy Mike
Published: September 2021

Almost three decades of studying freshwaters in New Zealand has revealed to me that our lowland freshwater ecosystems are in dire straits and that there is no hint of improvement, or even a slowing of degradation. The leading cause of their demise is landuse change, specifically the rampant and extreme intensification of farming. The response of government, both central and local, has been an abject failure to limit this intensification and its resultant harm. Key to these regulatory failures by authorities charged with protecting freshwaters has been the influence at all levels of powerful agricultural industry lobby groups.
Foxes Guarding the Hen House?
Authors: Blumhardt Hannah
Published: September 2021

For the first time since the enactment of the Waste Minimisation Act 2008, New Zealand is applying regulated (or mandatory) product stewardship to several priority products. By making those who manufacture, sell and use products responsible for minimising the waste those products cause, well-designed product stewardship schemes can act as a critical tool in the transition to a circular economy. However, the New Zealand government has put its faith in industry to lead scheme design. Such an approach threatens to vitiate robust, ambitious schemes and foreground industry interests over those of wider society and the natural environment. This article juxtaposes the radical potential of product stewardship against the probable outcome of industry-led schemes, and recommends reforms that the minister for the environment should pursue in order to shift the dial towards more inclusive design of product stewardship schemes.
Magic Weapons and Foreign Interference in New Zealand
Authors: Brady Anne-Marie
Published: September 2021

In March 2021, the New Zealand Security Intelligence Service (SIS) launched a remarkable campaign to inform the New Zealand public on the risk of foreign interference. In New Zealand, reference to ‘foreign interference’ almost always relates to the foreign interference activities of the Chinese Communist Party (CCP) government. New Zealand has been severely affected by CCP foreign interference. For the Ardern government it was never a matter of ‘whether’ New Zealand would address this issue, but ‘how’. The SIS’s unprecedented public information campaign is part of a significant readjustment in New Zealand–China relations since 2018. This article documents some of those changes

Authors: Al Sowielem L. S. , El Zubier A. G.
Published: September 2021

The compliance of hypertensive patients and patients’ knowledge and misconceptions about hypertension were investigated in a cross-sectional study of all hypertensive patients [190] attending four primary health care centres in Al-Khobar, Saudi Arabia. The mean age was 49.9 +/- 11.7 years. The overall compliance rate was 34.2%;the rate was lower in those aged < 55 years than older patients [26.2% versus 48.5%;P < 0.001]. It was also lower among educated than illiterate patients [30.4% and 38.1% respectively;P < 0.001]. About 44% of patients thought that they should stop drug treatment once they achieved blood pressure control and 66.3% believed that emotional stress was the most important etiological factor in hypertension. The findings indicate that there is a clear need for health education of hypertensive patients
Reliability Improvement of Offshore Structural Steel F690 Using Surface Crack Nondamaging Technology
Authors: Lee Weon-Gu , Gu Kyoung-Hee , Kim Cheol-Su , Nam Ki-Woo
Published: September 2021

Microcracks can rapidly grow and develop in high-strength steels used in offshore structures. It is important to render these microcracks harmless to ensure the safety and reliability of offshore structures. Here, the dependence of the aspect ratio (As) of the maximum depth of harmless crack (ahlm) was evaluated under three different conditions considering the threshold stress intensity factor (ΔKth) and residual stress of offshore structural steel F690. The threshold stress intensity factor and fatigue limit of fatigue crack propagation, dependent on crack dimensions, were evaluated using Ando's equation, which considers the plastic behavior of fatigue and the stress ratio. ahlm by peening was analyzed using the relationship between ΔKth obtained by Ando's equation and ΔKth obtained by the sum of applied stress and residual stress. The plate specimen had a width 2 W = 12 mm and thickness t = 20 mm, and four value of As were considered: 1.0, 0.6, 0.3, and 0.1. The ahlm was larger as the compressive residual stress distribution increased. Additionally, an increase in the values of As and ΔKth(l) led to a larger ahlm. With a safety factor (N) of 2.0, the long-term safety and reliability of structures constructed using F690 can be secured with needle peening. It is necessary to apply a more sensitive non-destructive inspection technique as a non-destructive inspection method for crack detection could not be used to observe fatigue cracks that reduced the fatigue limit of smooth specimens by 50% in the three types of residual stresses considered. The usefulness of non-destructive inspection and non-damaging techniques was reviewed based on the relationship between ahlm, aNDI (minimum crack depth detectable in non-destructive inspection), acr N (crack depth that reduces the fatigue limit to 1/N), and As.
Effect of water salt composition on oil spill dispersant efficiency determined in laboratory conditions

Published: September 2021

The effect of the salt composition of water (model aqueous solutions of NaCl and artificial sea salt Instant Ocean, as well as water from the Pechora Sea) on the effectiveness of oil spill dispersants determined in laboratory conditions is studied. The efficiency of dispersants (Finasol OSR 52, Slickgone NS and Slickgone EW) was evaluated three samples of crude oil produced in the Russian Federation. Those oil samples of different composition and properties were used at fixed values of the dispersant-oil ratio  (1:10), water temperature (20 ± 2°C) and salinity (35 ± 2%). It is shown that the effectiveness of the oil spill disper­sant depends on  the nature (composition) of water in which the oil is dispersed, other things being the same. An anomalous behavior of one of the oil samples was found when it was dispersed in an aqueous so­ lution of NaCl under the action of Finasol OSR 52 and Slickgone EW Good convergence of the numerical values of the efficiency of dispersants was obtained when testing them in an aqueous solution of artificial sea salt Instant Ocean and in the water of the Pechora Sea. It is noted that to assess the effectiveness of dispersants in laboratory conditions, it is advisable to use water of the natural object in which this disper­sant is planned to be used. Moreover, the possibility of using an aqueous solution of the artificial salt when its salt composition is similar to that for real sea water was noted.
Hepatitis C virus (HCV) incidence among men who have sex with men (MSM) living with HIV: results from the French Hospital Database on HIV (ANRS CO4-FHDH) cohort study, 2014 to 2017

Published: September 2021

Background

Despite the availability of highly effective direct-acting antivirals (DAAs) and the expected treatment as prevention (TasP) effect, transmission of hepatitis C virus (HCV) persists in men who have sex with men (MSM) who engage in high-risk sexual behaviours.

Aim

We aimed to estimate the incidence of primary HCV infection among MSM living with HIV in France when DAA was readily available.

Methods

We used data from a large French hospital cohort of persons living with HIV (ANRS CO4-FHDH) prospectively collected between 2014 and 2017. HCV incidence rates were calculated using person-time methods for HCV-negative MSM at inclusion who had serological follow-up from 1 January 2014 to 31 December 2017. Sensitivity analyses were performed by varying the main assumptions to assess their impact on the results.

Results

Of 14,273 MSM living with HIV who were initially HCV-seronegative, 330 acquired HCV during follow-up over 45,866 person-years (py), resulting in an overall estimated incidence rate of 0.72/100 py (95% CI: 0.65–0.80). HCV incidence significantly decreased from 0.98/100 py (95% CI: 0.81–1.19) in 2014 to 0.45/100 py (95% CI: 0.35–0.59) in 2017 (54% decrease; 95% CI: 36–67). This trend was confirmed by most of the sensitivity analyses.

Conclusion

The primary incidence of HCV was halved for MSM living with HIV between 2014 and 2017. This decrease may be related to unrestricted DAA availability in France for individuals living with HIV. Further interventions, including risk reduction, are needed to reach HCV micro-elimination in MSM living with HIV.
Mejoramiento de la producción de nogal pecanero por zinc en riego por goteo en suelos calcáreos
Authors: Olivas-Tarango Ana Luisa , Tarango-Rivero Socorro Héctor , Ávila-Quezada Graciela Dolores
Published: September 2021

El nogal demanda una considerable cantidad de zinc (Zn) para la actividad de enzimas dependientes de Zn que intervienen en el metabolismo de proteínas, azúcares, carbohidratos y auxinas. Por ello, el objetivo de este estudio fue evaluar la producción de nogales con aporte edáfico de 12 a 15 kg ha-1 zinc quelado mediante riego por goteo, además de la adición de un consorcio microbiano comercial en un estudio de tres años. El control fue el manejo convencional de fertilización con zinc foliar. La metodología propuesta en este trabajo, permitió obtener un kg adicional de nuez por árbol después de tres años. Este tratamiento permitió que el brote (21 contra 20.1 cm) y la hoja (39 contra 36.8 cm2) crecieran ligeramente mejor que el tratamiento de zinc foliar, y promovió el enriquecimiento de comunidades microbianas en el suelo rizosferico, así como la colonización ectomicorrízica de 69.9%. Además, el tratamiento de zinc quelado aplicado en riego por goteo evitó la pulverización nocturna, por lo tanto, este manejo en huertos de nueces ofrece a los productores una opción económica, ecológica y sustentable que les permite mejorar el rendimiento.

Authors: Martin Kathy
Published: September 2021

It is estimated that 54,000 new cases of Head and Neck Cancer will be diagnosed in the United States in 2021 (Cancer Facts and Figures, 2021). Head and Neck cancers represent those that originate from sites which include the nasopharynx, oropharynx, oral cavity and hypo-pharynx. In advanced cases, treatment modalities are combined to include surgery, radiation and chemotherapy. Expected side effects of treatment can include mucositis, dysgeusia, dysphagia, odynophagia, nausea, vomiting and xerostomia. These toxicities can contribute to dehydration, weight loss and malnutrition. This paper examines the current state of evidence as it pertains to nutritional outcomes for Head and Neck cancer patients receiving concurrent chemotherapy and radiation when prophylactic percutaneous endoscopic gastrostomy (PEG) tubes versus reactive tubes were used. A retrospective chart review was conducted to examine the following research question: Does prophylactic percutaneous gastrostomy tube placement improve nutritional outcomes in patients receiving concurrent chemotherapy and radiation for Head and Neck Cancer patients when compared to those patients with reactive PEG tubes placed. The results of this study identified that despite timing of tube placement, patients in both groups lost weight and showed signs of worsening nutritional outcomes as evidenced by decreased body mass index, total protein, and albumin levels. Advanced practice nurses are in a unique position to develop innovative approaches to enhance nutrition in this patient population. Risk assessment tools, interdisciplinary collaboration and the development of a Head and Neck cancer pre-habilitation clinic may improve nutritional outcomes in the Head and Neck cancer patient receiving cancer treatment.
Effect of Clinical Opiate Withdrawal Scale Educational Intervention on Intensive Care Unite Nurses' Knowledge and Confidence
Authors: Schneider Lauren
Published: September 2021

The opioid epidemic is a significant concern for the United States. Forty-eight and a half million Americans have either used illicit drugs such as heroin or have misused prescription opioid drugs. The exponential rise in opioid use increases the risk of opioid withdrawal, thus making opioid withdrawal assessment a top priority, especially for hospitalized individuals. The Clinical Opiate Withdrawal scale (COWS) is highly recommended to assess opioid withdrawal in hospitalized individuals and is well supported by the American Society of Addiction Medicine National Practice guideline and the World Health Organization. Despite the availability of reliable opioid withdrawal assessment scales, improper use and underuse of these scales are reported. Nurses education on the use of the COWS could address this gap. The purpose of this quality improvement project was to determine the effectiveness of an educational intervention concentrating on the COWS to improve critical care nurse’s knowledge and confidence in scale use. The quality improvement project utilized a pre-test, educational intervention and a posttest design. Twenty-eight out of the possible 60 critical care nurses participated in the quality improvement session. The mean scores on the pretest and post-test were 41.2 % and 83.5%, respectively. This showed a percentage increase in knowledge of 42.3. Furthermore, participants reported higher level of confidence in their ability to utilize the COWS. Receipt of COWS education could promote proper use of the scale. The advanced practice nurse can assist in establishing and implementing educational programs that focus on the importance of opioid withdrawal assessment through evidence-based practice.

Several empirical studies have shown that decision makers tend to experience an escalation of commitment bias, namely a tendency to continue investment projects that are less profitable, even though there is information of the less profitable project performance and that other available alternative investment opportunities are more profitable in the future. This study aims to improve the manager's decision making behavior model by considering the ethical environment as one of the factors that influence investment project evaluation decisions. More specifically, this study empirically examines the ethical environment as a strategy to reduce the tendency for escalation of commitment behavior. This study uses a laboratory experimental method with a 2 x 2 factorial experimental design between subject with adverse selection (present/absent) and ethical environment (strong/weak). The research sample consisted of 246 undergraduate and postgraduate students in Accounting and Management who acted as investment project managers. Based on ANOVA analysis results, it shows that managers who experience adverse selection conditions tend to continue unfavorable projects (conduct escalation of commitment). In addition, the results of this study also show that the tendency of managers to end investment projects that are not profitable for managers who are in a condition of a strong ethical environment will be greater when they experience adverse selection conditions compared to when they do not experience it

Previous research has mostly examined the phenomenon of escalation of commitment in the context of decision making by managers in an investment project. However, in the capital budgeting process, before making investment decisions managers tend to consider information produced by accountants. This study examines the phenomenon of escalation of commitment using the perspective of supporting role of accountants as the party that provides information for investment decision making by managers, especially in the presence of sunk costs. This study uses a laboratory experimental method. The sample in this study are 156 undergraduate students majoring in Accounting who had passed Financial Accounting and Management Accounting courses. Based on the results of the independent sample t-test, it shows that accountants who experienced sunk cost conditions tend to provide reports that directed managers towards escalation of commitment behavior compared to accountants who do not experience sunk cost conditions. The presence of sunk cost makes accountants have better mind frame to get the possibility of profit compared with a definite loss so that the decisions they make tend to provide reports that lead to the escalation of commitment behavior

The process of semen freezing causes an increase in free radicals concentration which can damage spermatozoa. The addition of natural ingredients in semen diluent is expected to solve this challenges. One of the natural ingredients that can be used is jamblang (Syzygium cumini) leaves. The objective of the current study was to investigate the quality of spermatozoa in Aceh cattle which was added with jamblang leaves extract in skim milk- egg yolk extender during pre-freezing and post-thawing. This study applied Completely Randomized Design (CRD) with 5 treatments and 5 replications. The treatments consisted of J0 = skim milk-egg yolk; J1 = skim milk-egg yolk + jamblang leaves extract 0.2%; J2 = skim milk-egg yolk + jamblang leaves extract 0.4%; J3 = skim milk-egg yolk + jamblang leaves extract 0.6%; and J4 = skim milk-egg yolk + jamblang leaves extract 0.8%. The parameters observed in this study were the percentage of motility and viability of frozen semen of Aceh cattle. The data obtained were analyzed using Analysis of Variance (ANOVA) and if differences were found, then it would be continued with Duncan's Multiple Distance test. The results showed that the addition of jamblang leaves extract in egg yolk skim milk significantly affected the percentage of motility during pre-freezing and post-thawing, significantly affected spermatozoa viability during pre-freezing and significantly affected the spermatozoa viability during post-thawing. J3 treatment (jamblang leaves extract 0.6 gram/100 ml) it should be higher than the other treatment, where the percentage of motility at pre-freezing and post-thawing were 55.48% and 52.71%, respectively, and the percentage of viability during pre-freezing and post-thawing were 56.59% and 53.94%, respectively. It was concluded that the addition of jamblang leaves extract in the skim milk-egg yolk extender affected the percentage of spermatozoa motility and viability of Aceh cattle during pre-freezing and post-thawing.
