APRILIA, Fitri,KUSUMAWATI, Andriani Korea Distribution Science Association 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.2

The contribution made by the tourism sector is strategic enough to provide job opportunities and increase the state's foreign exchange which will be followed by development in the information and technology sectors. The population of this study includes all domestic tourists who visit the Batu City Angkut Museum over 17 years of age and who have obtained information via eWOM from other tourists. Based on the measurement, a minimum of 160 respondents must be selected as the research sample. Non-probability sampling techniques are used to select samples. Social media had been used by companies to provide information, services, and products related to tourism, and it was utilized by tourists to share information about their traveling experiences. Nowadays, tourists have become more selective and critical in selecting their destinations as they have become good observant in finding adequate information about certain destinations before deciding to visit the place. This reaction can be influenced by positive eWOM communication, positive image, and trust given to certain tourist destinations. Therefore, improving the number of visits requires the management of certain tourism service companies to apply proper marketing strategy and provide various advantages and best service quality to attract more visitors and give satisfaction to visitors.

여행을 계획하는 일은 매우 복잡하고 많은 시간을 필요로 한다. 여행 계획을 정할 때에는 보통 관심지점(point of interests, POIs)을 선택하고 그에 따른 다양한 제약 조건들을 고려하여 일정을 계획 한다. 관심 지점을 선정할 때 친구들에게 의견을 묻거나 인터넷에서 직접 정보를 찾으며 여행사의 도움을 받기도 한다. 하지만 이러한 방법들은 다음과 같은 어려움이 있다. 친구들에게 의견을 묻는 경우에는 친구들이 방문해 보지 못한 장소에 대한 정보를 얻기 어렵고 인터넷에서 정보를 찾는 경우에는 오히려 너무 많은 여행 정보들 때문에 필요한 정보를 탐색하고 정리하는데 많은 시간이 필요하며 여행사의 도움을 받을 때에는 여행 일정이 여행을 제공해주는 업체들 쪽으로 편중될 우려가 있다. 이러한 문제를 해결하기 위해 본 논문에서는 여행 일정 계획 시스템인 CYTRIP을 제안한다. CYTRIP은 웹 기반의 추천 시스템으로써, 여행 정보를 공유할 수 있는 공간을 제공하고, 이를 통해 참여자들의 집단 지성에 따른 관심 지점을 추천 받는다. 그리고 PDDL3를 통해 추천된 지점들의 시간적, 공간적 제약조건 따라 여행 일정이 자동으로 생성되며 이렇게 생성된 일정은 지도 위에 표시되어 사용자에게 제공된다. 여행을 계획할 때에 정해진 기간 동안 모든 추천 관심지점을 방문할 수 없는 경우가 발생한다. 이러한 문제를 피하기 위해 정해진 시간에 방문 가능한 관심 지점들의 후보 집합을 선택하고 이 후보 집합들에 대한 여행 일정을 생성한다. 제안하는 시스템의 성능평가를 위해 사용자 평가를 실시하였다. 사용자 평가를 위해 한국관광공사에서 제공하는 데이터를 활용하였고 평가 결과 제안하는 시스템이 여러 참여자들의 집단 지성을 통해 여행 일정을 계획하는데 유용하다는 것을 알 수 있었다. Planning a multi-day trip is a complex, yet time-consuming task. It usually starts with selecting a list of points of interest (POIs) worth visiting and then arranging them into an itinerary, taking into consideration various constraints and preferences. When choosing POIs to visit, one might ask friends to suggest them, search for information on the Web, or seek advice from travel agents; however, those options have their limitations. First, the knowledge of friends is limited to the places they have visited. Second, the tourism information on the internet may be vast, but at the same time, might cause one to invest a lot of time reading and filtering the information. Lastly, travel agents might be biased towards providers of certain travel products when suggesting itineraries. In recent years, many researchers have tried to deal with the huge amount of tourism information available on the internet. They explored the wisdom of the crowd through overwhelming images shared by people on social media sites. Furthermore, trip planning problems are usually formulated as ‘Tourist Trip Design Problems’, and are solved using various search algorithms with heuristics. Various recommendation systems with various techniques have been set up to cope with the overwhelming tourism information available on the internet. Prediction models of recommendation systems are typically built using a large dataset. However, sometimes such a dataset is not always available. For other models, especially those that require input from people, human computation has emerged as a powerful and inexpensive approach. This study proposes CYTRIP (Crowdsource Your TRIP), a multi-day trip itinerary planning system that draws on the collective intelligence of contributors in recommending POIs. In order to enable the crowd to collaboratively recommend POIs to users, CYTRIP provides a shared workspace. In the shared workspace, the crowd can recommend as many POIs to as many requesters as they can, and they can also vote on the POIs recommended by other people when they find them interesting. In CYTRIP, anyone can make a contribution by recommending POIs to requesters based on requesters’ specified preferences. CYTRIP takes input on the recommended POIs to build a multi-day trip itinerary taking into account the user’s preferences, the various time constraints, and the locations. The input then becomes a multi-day trip planning problem that is formulated in Planning Domain Definition Language 3(PDDL3). A sequence of actions formulated in a domain file is used to achieve the goals in the planning problem, which are the recommended POIs to be visited. The multi-day trip planning problem is a highly constrained problem. Sometimes, it is not feasible to visit all the recommended POIs with the limited resources available, such as the time the user can spend. In order to cope with an unachievable goal that can result in no solution for the other goals, CYTRIP selects a set of feasible POIs prior to the planning process. The planning problem is created for the selected POIs and fed into the planner. The solution returned by the planner is then parsed into a multi-day trip itinerary and displayed to the user on a map. The proposed system is implemented as a web-based application built using PHP on a CodeIgniter Web Framework. In order to evaluate the proposed system, an online experiment was conducted. From the online experiment, results show that with the help of the contributors, CYTRIP can plan and generate a multi-day trip itinerary that is tailored to the users’ preferences and bound by their constraints, such as location or time constraints. The contributors also find that CYTRIP is a useful tool for collecting POIs from the crowd and planning a multi-day trip.

Objective: This study investigated the effects of feeding anthocyanin-rich black cane treated with ferrous sulfate and molasses on animal performance, rumen fermentation, microbial composition, blood biochemical indices, and carcass characteristics in meat goats. Methods: Thirty-two Thai-native×Anglo-Nubian crossbred male goats (14.47±2.3 kg) were divided equally into two groups (n = 16) to investigate the effect of feeding diet containing 50% untreated anthocyanin-rich black cane silage (BS) vs diet containing anthocyaninrich black cane silage treated with 0.03% ferrous sulfate and 4% molasses (TBS) on average daily gain (ADG) and dry matter intake (DMI). At the end of 90 d feeding trial, the goats were slaughtered to determine blood biochemical indices, rumen fermentation, microbial composition, and carcass characteristics differences between the two dietary groups. Results: Goats fed the TBS diet had greater ADG and ADG to DMI ratio (p<0.05). TBS diet did not affect rumen fluid pH; however, goats in the TBS group had lower rumen ammonia N levels (p<0.05) and higher total volatile fatty acid concentrations (p<0.05). Goats in the TBS group had a higher (p<0.05) concentration of Ruminococcus albus but a lower (p<0.05) concentration of methanogenic bacteria. The TBS diet also resulted in lower (p<0.05) thiobarbituric acid-reactive substances concentration but higher (p<0.05) total antioxidant capacity, superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase concentrations in blood plasma, while having no effect on plasma protein, glucose, lipid, immunoglobin G, alanine transaminase, and aspartate aminotransferase. Meat from goats fed the TBS diet contained more intramuscular fat (p<0.05) and was more tender (p<0.05). Conclusion: In comparison to goats fed a diet containing 50% untreated anthocyanin-rich black cane silage, feeding a diet containing 50% anthocyanin-rich black cane silage treated with 0.03% ferrous sulfate and 4% molasses improved rumen fermentation and reduced oxidative stress, resulting in higher growth and more tender meat.

Development of strategies to manufacture low-salt meat products - a review

( Gracia Henreita Suci Aprilia ),( Hyeong Sang Kim ) 한국축산학회 2022 한국축산학회지 Vol.64 No.2

Urbanization is usually followed by changes in eating habits, with a specific trend toward the consumption of ready-to-eat products, such as processed foods. Among the latter, meat products are known contributors to high dietary sodium owing to salt addition. Salt plays an essential role in maintaining the quality of meat products in terms of acceptability and safety. However, an excessive salt intake is linked to high blood pressure and cardiovascular diseases. Hence, several studies have been competing for the discovery of salt alternatives performing in a similar way as common salt. A number of replacements have been proposed to reduce salt consumption in meat products while taking into account consumer preferences. Unfortunately, these have resulted in poorer product quality, followed by new adverse effects on health. This review addresses these recent issues by illustrating some established approaches and providing insight into further challenges in developing low-salt meat products.

Adsorption of Pb(II) Ions from Aqueous Solution Using Activated Carbon Prepared from Areca Catechu Shell: Kinetic, Isotherm and Thermodynamic Studies

Muslim, A.,Aprilia, S.,Suha, T.A.,Fitri, Z. Korean Chemical Society 2017 대한화학회지 Vol.61 No.3

This study proposed adsorption of Pb(II) ions from aqueous solution using activated carbon prepared from areca catechu shell (ACS AC) using Timphan Method. The effects of independent variables on adsorption kinetic and isotherm have been investigated by conducting experiments in batch mode at neutral pH. The structural characterization of adsorbent was done by FT-IR and SEM analysis. The Pb(II) adsorption was correlated very well with the pseudo second-order kinetic (PSOKM) and Langmuir isotherm models (LIM). Increasing NaOH mass for activation and adsorption temperature increased weakly all the parameters of adsorption kinetic and isotherm. The Pb(II) ions adsorption capacity of the ACS AC at 27 and $45^{\circ}C$ was 50.51 and 55.25 mg/g, respectively. Thermodynamic parameters were determined, and the results confirmed the Pb(II) ions adsorption should be endothermic and spontaneous process, and both physical and chemical adsorption should be taken place.

The Contribution of Social Media Value to Company’s Financial Performance: Empirical Evidence from Indonesia

Muhammad MIQDAD,Siska Aprilia OKTAVIANI 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.1

This article aims to explore the contribution of social media value to a company’s financial performance in a digital environment economy since the awareness of companies and investors in the use of social media opens up new mechanisms for disseminating information. Quantitative method is used in this study with Multivariate Analysis of Variance as the analysis tool. The data used is secondary data gathered from Indonesia Stock Exchange (IDX) using 308 companies as samples. In the multivariate test, four kinds of multivariate significance tests were carried out, namely Pillai Trace, Wilk Lambda, Hotelling’s Trace, and Roy’s Largest Root. It was found that social media value has a small contribution in the difference of the level of profitability and the value of the company in Indonesia, but it doesn’t have a contribution to the difference of the level of liquidity. The contribution was an implication of online Word of Mouth (WOM) motives which are interrelated with signal theory and as additional information for investors in relation to single-person decision theory. This study provides an insight into the importance of social media management considering that the world of digital economy will continue to develop, so companies in Indonesia need to take advantage of these opportunities.

The Gate Keeper System in Accessing Health Services, Can It Prevent Cirrhosis Hepatitis Patient from Out of Pocket?

( Lintong Hottua Simbolon ),( Aprilia G. A. Maay ),( Rosinta Hotmaida Pebrianti Purba ) 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: In Indonesia, Cirrhosis Hepatitis is the 5th disease with the most social insurance claims after heart disease, stroke, kidney failure, and cancer. Hepatitis Cirrhosis case-control program is focused on preventing Mother to Child Transmission (PPIA) because 95% of hepatitis B transmission is vertical, ie from mothers who are positive for hepatitis B to the fetus. Thus, every baby (0-11 months old) is required to get a complete basic immunization consisting of 1 dose of Hepatitis B, 1 dose of BCG, 3 doses of DPT-HB-HiB, 4 doses of polio drops, and 1 dose of measles / MR. Program coverage reaches 90.61% in 2018 nationally. Nevertheless, the prevalence of hepatitis sufferers increased from 0.2% in 2013 to 0.4% in 2018, equivalent to 13.5 million sufferers dominated from remote provinces such as Papua Island and the Nusa Tenggara Islands. This number makes Indonesia the 3rd country in Asia with the most cases of chronic hepatitis B sufferers after China and India. This study aims to analyze and evaluate risk factors of national policy objectives implementation. Methods: Using the juridical-empirical approach, this study analyzes whether Indonesia’s health service practices conformity is in line with national policy objectives. In accordance with National Social Security and Law Number 11 of 2009 concerning Article 19 of Law concerning Social Welfare, the government is obliged to ensure equal health services access and facilities due to Universal Health Coverage including promotive, preventive, curative, and rehabilitative services by adhering to the cooperation principle (gotong royong). Results: JKN aims to protect the citizens from financial risks through the Social Security Organizing Agency (BPJS) that will cover all types of diseases (Minister of Health Regulation 28/2014). Thus, the cost burden is allocated by the BPJS for curative Cirrhosis Hepatitis absorbs U $ 21.17 million in 2017 and U $ 14 million in 2018. Meanwhile, almost 784.3 thousand individuals each year fall into poverty as a result of hepatic health costs. However, the provisions on the National Formulary 2017 on drugs to reduce symptoms such as pegylated injection, adefovir dipropyl, entecavir, lamivudine, ribavirin, tenofovir, and telbivudine are limited in number and can only be accessed at level 1 facilities at hospitals that are difficult to access community in remote areas. Further, when performing surgery, it turns out there are costs that are not covered and eventually patients become difficult to pay for health care costs. Meanwhile, patients fall into poverty as a result of Cirrhosis Hepatitis health costs. The patient has to spend the cost of illness that is borne for life by 2.7 percent of total household consumption expenditure. This has an impact on reducing the quality of life of patients. Conclusions: The government has not achieved the goal of eliminating Cirrhosis Hepatitis patients from “out of pocket” yet. The government needs to overcome the health policies overlapping and develop hospital formularies due to prevention and health promotion programs. Further, the national health insurance program needs to be allocated more effectively for the construction of the health infrastructure in remote areas to improve the patient’s QoL.
