Authors: Gladian Dzaky Dirga Ananda  
Published: March 2024

Sumatera Utara merupakan salah satu provinsi di Indonesia yang memiliki beragam sektor pariwisata. Menurut badan pusat statistic provinsi sumatera utara pada bulan Maret terdapat 16.299 kunjungan wisatawan mancanegara pada bulan Maret tahun 2023. Pariwisata yang cukup terkenal yang berada di provinsi Sumatera Utara yaitu Danau Toba. Hal itu dikarenakan di Danau Toba selain terkenal dengan keindahan alamnya, di Danau Toba juga kaya akan kebudayaan dan tradisi-tradisi setempat. Namun selama ini rekomendasi tujuan wisata biasanya dari mulut ke mulut, media massa, media sosial, dan browsing. Hal ini membuat tidak semua objek wisata diketahui oleh banyak orang, dikarenakan kurangnya informasi maupun letak objek wisata yang terpencil. Pada penelitian ini, peneliti akan merancang dan membangun sebuah aplikasi yang mana di dalam aplikasi tersebut terdapat informasi seputar objek wisata yang terdiri dari titik lokasi objek, jarak tempuh dari suatu tempat, fasilitas yang tersedia, jam operasional objek wisata, dan lain sebagainya. Aplikasi yang dirancang berbasis android, sehingga memudahkan para wisatawan untuk menggunakan atau memanfaatkan aplikasi tersebut. Metode yang digunakan dalam pengembangan sistem berupa waterfall, sedangkan aplikasi yang dibangun menggunakan layanan Location Based Service (LBS), dengan memanfaatkan Global Positioning system (GPS). Aplikasi ini diharapkan dapat menjadi solusi untuk wisatawan yang ingin mengunjungi wisata – wisata yang berada di Danau Toba, serta aplikasi ini dapat menjadi media promosi dan media pengenalan objek wisata lainnya yang belum dikenali banyak orang dengan berbasis teknologi.

Laboratory evaluation of a bio-insecticide candidate from tangerine peel extracts against Trialeurodes vaporariorum (Homoptera: Aleyrodidae)
Authors: Flores Nancy , Prado Julia , Espin Rosario , Rodríguez Hortensia , Pais-Chanfrau José-Manuel 
Published: March 2024

Background
The excessive use of synthetic insecticides in modern agriculture has led to environmental contamination and the development of insect resistance. Also, the prolonged use of chemical insecticides in producing flowers and tomatoes in greenhouses has caused health problems for workers and their offspring. In this study, we analyzed the efficacy of mandarin peel (Citrus reticulata L.) essential oil (EO) as a natural insecticide against greenhouse whitefly (Trieurodes vaporariorum W., Homoptera: Aleyrodidae), a common pest in greenhouse production of different crops.

Methods
Petroleum ether (PET) and n-hexane (HEX) were used as solvents to extract essential oil (EO) from tangerine peels.

Results
The yield of EO was 1.59% and 2.00% (m/m) for PET and HEX, respectively. Additionally, the insect-killing power of EO was tested by checking how many greenhouse whiteflies died at different times. The results showed that PET and HEX extracts of tangerine EO effectively controlled greenhouse whiteflies. Furthermore, with both solvents, a 12.5% (v/v) application was as practical as the commercial insecticide imidacloprid. Further characterization tests with the polarimeter, FTIR, HPLC-RP, and GC-MS showed that the essential oil (EO) contained about 41% (v/v) of d-limonene and that this compound may be responsible for the observed insecticidal properties.

Conclusion
Therefore, tangerine peel essential oil is an excellent botanical insecticide candidate for controlling greenhouse whiteflies.
Process Optimization in Manufacturing Industries Using Simulation Technologies

Published: March 2024

The industrial application and importance of simulation technologies for process optimization in manufacturing industries cannot be underestimated. Adequate monitoring of raw materials processing to finished products and their conveyance to the end users is required together with profits and cost optimization to ensure the company attained the set goals. Thus, it is imperative to adopt the use of simulation-based optimization tools. This paper succinctly discussed the importance of simulation-based optimization technologies as effective techniques in manufacturing industries. The concept of process optimization, simulation and simulation techniques as related to manufacturing were discussed. Various techniques of simulation-based optimization in manufacturing were presented. These include Monte Carlo simulation, discrete event simulation and system dynamics. Also, typical examples of manufacturing optimization techniques were stated. These include Just-in-Time, statistical process control, total quality management, six sigma, value stream mapping and computer numerical control. Various applicable areas of simulation-based optimization technologies in manufacturing were also addressed. However, resistance to change, lack of expertise, lack of data, unintended consequences, over-reliance on technology and insufficient testing are the associated problems to simulation-based optimization in manufacturing. In conclusion, relevant simulation-based optimization technologies should be adopted by various manufacturing companies to ensure profit maximization while still keeping the chain between production of good and supply to customers intact.
Evaluation of the Effect of 2022 Flooding on Business Activities in Lokoja Metropolis

Published: March 2024

Flooding has become a global issue and its effect varies with the level of flooding at a given period. In the wake of urban floods, public and commercial institutions are currently finding it difficult to develop and assess risk management and adjustment methods that include land use planning and urbanization patterns in addition to systems for flood prevention and early notifications. Flooding is one of the negative effects of global warming and most countries in the world are making effort to reduce its associated effects. This study examined the effect of 2022 flooding on business activities in Lokoja Metropolis. The study used a survey research design and a Taro Yamani sample size selection method to select 400 respondents. Questionnaire was administered to the respondents based on simple random selection and the data was analysed using Analysis of Variance (ANOVA) regression. The findings show that 2022 flooding exerts negative and statistically significant effect on business activities. there was low business patronage and high cost of goods during the flood period. Also, the findings show that small businesses were mostly affected during the flood period than large businesses. The study therefore recommends dredging of the River Niger and River Benue to increase water holding capacity. Also, there should be enactment of laws against building or citing of businesses along flood route to reduce the level of damages during flooding
Vibration tests and analysis of a model arch dam
Authors: Balsara Jimmy P. , Norman C. Dean 
Published: March 2007

AbstractVibration tests were conducted on a 1/24‐scale model of the North Fork Dam, a double‐curvature arch dam, to determine natural frequencies, mode shapes and hydrodynamic pressures. The mode shapes and natural frequencies were determined from tests using two vibrators mounted on the crest of the dam. Hydrodynamic pressures at the dam/reservoir interface were determined from tests in which the vibrator was attached to the downstream foundation of the dam. The hydrodynamic pressures calculated using Westergaard's theory and a theory for arch dams developed by Perumalswami and Kar accurately predicted the measured pressure at frequencies below the first mode frequency of the dam. The differences in the two theories were insignificant.The Structural Analysis Program (SAP), a linear three‐dimensional (3‐D) finite element code, was used to compute mode shapes and frequencies for the dam with its base fixed and with a foundation. Numerical solution schemes used in the finite element analysis consisted of a Ritz analysis and a subspace iteration method. Calculations were conducted for both full and empty reservoir conditions.The accuracy of the Ritz analysis improved considerably as more nodes in flexible regions of the dam were loaded. However, the lowest eigenvalues were computed using the subspace iteration method. For the full reservoir, the natural frequencies decreased by 20‐30 per cent when the foundation was included in the finite element model. The difference was less when the reservoir was empty. The calculations using the subspace iteration scheme and including the foundation agreed closely with experimental mode shapes and corresponding natural frequencies.
Torsional response of structures to obliquely incident seismic sh waves
Authors: Luco J. E. 
Published: March 2007

AbstractA study is made of the torsional response of an elastic structure placed on a rigid circular foundation supported on an elastic half‐space and subjected to the action of obliquely incident plane SH waves. The problem is solved by considering first the steady‐state response of a massless rigid foundation excited externally by a harmonic torque and through the soil by an obliquely incident plane SH wave. In a second stage the coupling between the structure and the soil is considered to obtain the torsional response at the base and top of the superstructure. The results obtained indicate a range of conditions under which the torsional effects will be most pronounced.
Vibrations of a nuclear power station charge hall
Authors: Jeary A. P. , Irwin A. W. 
Published: March 2007

AbstractIn an effort to determine the nature and size of the response of unusually shaped power station buildings, an investigation of one power station building has been made, both theoretically and experimentally. The dynamic response of the structure to wind excitation has been monitored, analysed and compared with theoretical values obtained from an analysis of a simplified structure. The shapes of pure modes of vibration are consistent with the predicted shapes, and correlation between measured and predicted frequency is better than 10 per cent. Damping measurements from the experimental study are included where the signal/noise ratio permitted, and these were found to be in a range that is consistent with values found in other types of steel construction.
Industrialization and Labor Response: Notes Toward the Construction of a Multi-Level Data Structure
Authors: Lafferty W.M. 
Published: March 2007

This paper is a broad attempt at a multi-level conceptualization of social change. It proceeds by taking a concrete research problem (the relationship between industrialization and the response of labor) and following it through successive stages of conceptualization, model-building, and the construction of an integrated structure for operationalization. The purpose of the paper is thus twofold; specifically, it presents a theory, model and data-gathering approach for the concrete problem at hand and, generally, it outlines possible theoretical and causal links among three distinct levels of social phenomena. It begins by depicting selected concepts from five different theorists in a conglomerate model which shows posited conceptual links within a causal range. It then proceeds to build up a multi-level framework around the three levels of ecological aggregate, organizational structure, and the individual actor. The theoretical nature of human ecology is presented as especially appropriate for analysis of change variables and the relationship of organiza tional structure to the ecological base is defined. The communal unit is defended as a contextual base and the individual is related theoretically to both this base and the level of emergent structure. A more complete categorization of contextual and backround variables is then added to that of the existing litera ture, and the nature of these variables is made more precise in terms of the multi-level structure. Finally an attempt is made to integrate, in a determinate fashion, the three "incommensurate" levels. This is done by relying on prin ciples from ecological psychology whereby the concepts organism-environ ment, inside-outside, and thing-medium are used to postulate possibilities for cross-level causality. The end product is a multi-level, ecologically-based data structure for the analysis of dynamic social variables. An example is then presented of its application to the relationship between industrialization and labor response in Norway.
Corporeality and Its Fates in History
Authors: Falk Pasi 
Published: March 2007

The question is: how to thematize the historicalness of the human body and corporeality. The first part of the article deals with the changing position of the body and corporeality as a part of Order The order is in this context defined broadly, referring both to socio-practical structures and cultural meaning structures. The approach may be charactenzed as a synthesis of social, cultural and conceptual history (partly inspired by Michel Foucault's conceptions of archeology & genealogy). The historicalness of the body and corporeality is structured in a setting where the body is related to the Other: spirit, soul, reason and self The historical change of these binary oppositions is related to the increasing instrumentalization of the body - considered from two aspects: one's own body and another's (own) body Further it is shown how these two aspects are combined in modern society: the body as a means of expression acquires a dominant role on the basis of corporeal equality and individuality. In the latter part of the article an approach is formulated to overcome the paradox of nature-culture parallelism in the definitions of the human body and corporeality. A fundamental distinction is made between the physical body (corporeal being) and corporeality, the latter being interpreted (through a critical reading of Georges Bataille's conceptions) as a central area of transgression. The concept of transgression allows an interpretation of corporeality as a cultural dynamics oscillating between the 'normal' (order/ everyday/profane) and the 'hyper-normal' state (liminality/fête/sacred). Thus it is possible to conceptualize corporeality - and now especially the sensual existence of man - in its historicalness. Finally, a distinction is made in the two dimensions of corporeality - the expressive and the experience aspect- which explains the paradox of two opposite interpretations of the historical fates of corporeality in modern society. Along the increasing instru mentalization and shielding of the body also the 'sensitiveness' to bodily pleasures is increasing. But on the other hand there is a clear shift of emphasis from the expressive aspect to the experience aspect of corporeality.
Social Structure and Union Character
Authors: Scheuer Steen 
Published: March 2007

Is there a difference between manual and white-collar unions? And if so: What are the bases for especially white-collar unions if they differ to a great extent in collectivist attitudes or with regard to 'untonateness' from their manual counterparts? These are the central questions raised in the recent literature about white-collar unionism (e.g. Price 1983). In this research note, the author argues that for unions in Denmark, professionalism is a very important part of union strategy. most notably among the major part of the white-collar unions On the basis of interviews with union officials and a survey, the author is able to show that professionahsm is a very active strategy within some unions in Denmark, and that it is especially active (and successful) where the occupation of the membership is linked to formal education. The empincal evidence is not given here, but in the author's book (Scheuer 1986), on which the following is based
Britain and Scandinavia: Their Relations within EFTA, 1960-1968

Published: March 2007

Archer, T. C. Britain and Scandinavia: Their Relations within EFTA, 1960-1968. Cooperation and Conflict, XI, 1976, 1-23. Relationships between Britain and Scandinavia in EFTA are examined using three variables: industrial base, attitude to the EEC, Nordic-British division. After initial cooperation in establishing EFTA, British relations with Scandinavia declined and after 1963 harmony on EFTA issues amongst the Scandinavians increased. Response to the British import surcharge illuminates the part Sweden played as bridgebuilder between Britain and Scandinavia. The role of EFTA's institutions in the relationship is shown and EFTA's usefulness for the four states is evaluated: by the end of the sixties EFTA provided fewer pay-offs and other trade options were taken up in Nordek and the EEC.

Direct Elections to the European Parliament: Toward a Federal Future?
Authors: Lodge Juliet 
Published: March 2007

Lodge, J. Direct Elections to the European Parliament: Toward a Federal Future? Cooperation and Conflict, XIII, 1978, 215-230. The direct election of the European Parliament is controversial for a variety of reasons. In particular it is expected to stimulate a change in the exercise of political authority in the EC to the advantage of the Commission and European Parliament. Following a discussion of the origins, nature and key elements of direct elections, the controversy over their implications for national governments is analysed. Zero sum assumptions are rejected, and two institutional models for the future EC examined. The static model represents minimalist approaches, whereas the dynamic model presages insti tutional developments along federal lines.
The Portuguese Revolution of 1974—75 and U.S. Foreign Policy
Authors: Oldberg Ingmar 
Published: March 2007

Oldberg, I. The Portuguese Revolution of 1974-75 and U.S. Foreign Policy. Coop eration and Conflict, XVII, 1982, 179-189 The article analyzes American reaction to the development in Portugal from April 1974 to November 1975. It is shown that the Administration took an alarmist view, that it was pessimistic concerning prospects for democracy, and that it was prone toward taking repressive measures, whereas other political actors at home and abroad exercised a restraining influence. Internationally, the Portuguese events gave rise to a new domino theory which was used to discourage West Europeans from going soft on Communism. The doctrinaire Moscow-orientated Portuguese Communists helped form the American attitude toward the Euro-Communists. In relation to the Soviet Union, the Americans used the detente process, culminating in the CSCE Conference in Helsinki in July 1975, as a means toward restricting Soviet aid to the Portuguese Communists. This seems to have worked, thus making American intervention less urgent. But the Portuguese Revolution paved the way for revolutionary regimes in Portugal's African colonies, which the Soviets and their allies could assist. This dealt the first serious blow to the American interest in detente with the Soviet Union.
Multipolarity and Modernization. Sources of China's Foreign Policy in the 1980s
Authors: Østergaard Clemens Stubbe 
Published: March 2007

Stubbe Østergaard, C. Multipolarity and Modernization. Sources of China's Foreign Policy in the 1980s. Cooperation and Conflict, XVIII, 1983, 245-267. Change in China's policy towards the USA, the USSR and the Third World is analysed in terms of its immediate causes, and by means of a framework categorizing types of sources, processes of change and reappraisals, as well as stabilizers affecting all of these. It is shown that there has been a descriptive reappraisal since Afghanistan, based on perceived changes in conditions of policy towards important power groupings, changes that imply global multipolarity. Domestic politics, in particular the drive towards economic modernization and its ideological ramifications, has resulted in a normative reappraisal of policy. It is found that purges and professionalization have affected composition of the foreign policy-making system, while conflicts between representatives of technocratic and bureaucratic constituencies have affected the balance of power within the system. The article describes the resulting policy, which is marked by independence and equidistance towards the superpowers.
The United Nations and the Resolution of International Conflicts
Authors: Väyrynen Raimo 
Published: March 2007

Väyrynen, R. The United Nations and the Resolution of International Conflicts. Cooperation and Conflict, XX, 1985, 141-171. The United Nations evolves in interaction with its external environment, which has changed in several ways during the postwar era. The distribution of power between major powers and in the global system as a whole have created the context in which the UN has served the functions of conflict manifestation, conflict resolution, and collective legitimization. The world organization operated in the conditions of US hegemony from 1948 to 1963 after a brief prelude as the coalition of victorious powers in 1945-1947. The gradual erosion of this hegemony and the process of decolonization blended the UN with a measure of both duopoly and fragmentation from 1964 to 1974. The processes of fragmentation and disagreement have become even more visible since the middle of the 1970s. Transformations in the international environment have also changed the types of conflicts which the UN is expected to manage and resolve. In particular the number and complexity of peripheral conflicts referred to the organ ization has increased, while it has faced considerable difficulties in handling them successfully. This fact, together with the general crisis of multilateral international cooperation, has given rise to efforts to rehabilitate the role of the United Nations in the maintenance of collective security.
