SIMULASI KEBIJAKAN PADA IMPLEMENTASI PERJANJIAN KOMPREHENSIF INDONESIA-AUSTRALIA (IA-CEPA) TERHADAP PASAR DAGING SAPI DOMESTIK

Abstrak Beberapa tahun terakhir, pemenuhan permintaan daging sapi di Indonesia masih bergantung pada impor khususnya dari Australia. Impor daging sapi dapat menstabilkan harga daging sapi domestik, tetapi di lain sisi dapat menekan pendapatan peternak lokal. Implementasi dari IA-CEPA adalah penghapusan tarif impor dan TRQ (Tariff Rate Quota) untuk komoditas sapi hidup. Penghapusan tarif menyebabkan harga sapi yang masuk ke Indonesia menjadi lebih murah dan memperbesar peluang peningkatan volume impor sapi hidup. Penelitian ini bertujuan untuk menganalisis skenario terbaik untuk meningkatkan kesejahteraan pelaku ekonomi dengan menggunakan model persamaan simultan 2SLS (two stage least square). Simulasi dilakukan untuk tiga skenario yaitu skenario penghapusan tarif, penetapan kuota, dan TRQ. Hasilnya menunjukkan bahwa skenario penghapusan tarif memberikan total peningkatan kesejahteraan pelaku ekonomi terbesar yaitu 115 miliar dengan rincian defisit 736 miliar bagi produsen, surplus 936 miliar bagi konsumen, dan defisit 85 miliar untuk penerimaan pemerintah. Oleh karena itu, skenario yang direkomendasikan adalah skenario penghapusan tarif pada impor sapi dari Australia. Kata Kunci: 2SLS, IA-CEPA, Pasar Daging Sapi Abstract Recently, demand fulfillment of beef in Indonesia depended on imports, especially from Australia. import can stabilize the domestic price of beef, but the other hand can suppress the income of local farmers. Implementation of IA-CEPA policies is the elimination of import tariff and TRQ (tariff rate quota) for live cattle commodities. Elimination of import tariff causes the price of cattle to enter Indonesia to be cheaper and increases the opportunity to increase the import volume of live cattle. The study aims to investigate the best scenario that can improve the welfare of economic actors using simultaneous equation model 2SLS (two-stage least squares). Three scenarios that simulated are eliminating tariff, setting quota, and TRQ. The result shows that eliminating tariffs gives the largest total welfare increase of economic actors that is 115 billion, with a 736 billion deficit for producers, 936 billion surplus for consumers, and 85 billion deficit for government revenue. Therefore, the policy recommendation is the scenario of eliminating tariffs on cattle imports from Australia. Keywords: 2SLS, IA-CEPA, Beef Market JEL Classification: C53, F12, F13

Evaluation of Multi-Objective Optimization Techniques for Resilience Enhancement of Electric Vehicles

The pervasiveness of electric vehicles (EVs) has increased recently, which results in the interdependence of power and transport networks. Power outages may adversely impact the transportation sector, and the available energy may not be sufficient to meet the needs of all EVs during such events. In addition, EVs will be used for diverse purposes in the future, ranging from personal usage to emergency response. Therefore, the allocation of energy to different EVs may have different degrees of societal-, community-, and individual-level benefits. To capture these diverse aspects, the energy allocation problem to EVs during outages is modeled as a multiobjective optimization (MOO) problem in this study. Three indices are formulated to quantify the value of different EVs for societies, communities, and individuals during outages, and, correspondingly, three objective functions are formulated. The formulated MOO problem is solved using the five most widely used MOO solution methods, and their performance is evaluated. These methods include the weighted-sum method, lexicographic method, normal boundary intersection method, min–max method, and nondominated sorting genetic algorithm II. To compare the performance of these methods, two indices are proposed in this study, which include the demand fulfillment index and total demand fulfillment index. The former is for analyzing the demand fulfillment ratio of different priority EVs, while the latter is for the demand fulfillment analysis of the whole EV fleet requiring a recharge. In addition, the computational complexity, variance, and additional constraints required by each method are also analyzed. The simulation results have shown that the lexicographic method has the best performance when the relative priorities are known, while the min–max method is the most suitable method if the priorities are not known.

Digital marketing as a strategy for fulfilling Eid Al-Adha beef cattle: A case study of start-up companies

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.

A MILP facility location model with distance value adjustments for demand fulfillment using Google Maps

In this manuscript, a facility location model was designed to support logistics operations, considering service distance limitations for demand fulfillment and a list of candidate locations within a supply chain. Consequently, an allocation model was designed using Mixed-Integer Linear Programming (MILP), in which a finite number of demand nodes could be satisfied by a set of supply nodes, considering not only the costs related to these locations but also restrictions aimed at improving the level of service based on distance. Besides, an integrated solution scheme was proposed that includes a macro in VBA language that calculates the distance between nodes using the web mapping service developed by Google Maps and solving the model through a branch and cut algorithm. Subsequently, a case study was executed where the supply operation of an important Colombian retail company is analyzed. The results reflected positive effects not only on costs but also on the prioritization of average distance traveled and on the satisfaction of store demand by distribution centers. Thus, the conditions in which the implementation of this model provides strategic benefits were verified, functioning as a tool to support decision making.

Sales and operations planning for new products: a parallel process?

PurposeThis paper aims to detail how a Sales and Operations Planning (S&OP) process can be designed to support the planning requirements of recently introduced products.Design/methodology/approachDesign science research was conducted to propose and implement an S&OP model for demand fulfillment after the introduction of new products. The results were analyzed using the CIMO (Context, Intervention, Mechanisms and Outcomes) logic, and two sets of design propositions were formulated.FindingsAn S&OP process for new products can reduce additional costs for market fulfillment by concentrating the planning efforts on new products, aligning organizational efforts, and increasing the sales and supply chain information’s update frequency.Research limitations/implicationsThe outcomes of S&OP new products were analyzed in a single organization and are limited to the contextual factors presented.Practical implicationsThis paper describes in detail how to organize an S&OP focused on new products. By considering the contextual factors and design propositions, managers can potentially increase the success of new products introduction (NPI) in their context.Originality/valueA specific S&OP process focused on new products is a viable solution and could co-exist with a traditional S&OP process. Moreover, we identified six contextual factors that influence the outcomes of the S&OP new products.

Integrated mathematical model based on a heuristic method for loading and routing of vehicles: application in a tobacco company

The vehicle-routing problem (VRP) combined with freight-loading problem is a complex and relatively recent issue studied by the scientific literature. This paper presents the formulation of a mathematical model and a procedure to solve this problem in a Cuban tobacco company aiming to determine the quantity of merchandise to be loaded on vehicles and the best route to be taken. For this purpose, a decomposition’s heuristic method was used and it was integrated with multiobjective programming by-goals and mixed binary quadratic programming. This approach allowed simplifying the problem and offering a satisfactory solution based on the demand fulfillment, the vehicles’ rational use and for searching the local optimums of the traffic load indicator. The model was tested in a case study and its feasibility evaluated based on a real operational situation in a tobacco company. Although the results of the application of the developed model does not imply reaching the optimal solution to the problem studied, it represents an opportunity for company’s performance improvement and it could be adapted and applied to other institutions dedicated to the same activities.

Online Demand Fulfillment Under Limited Flexibility

We study online demand fulfillment in a class of networks with limited flexibility and arbitrary numbers of resources and request types. We show analytically that such a network is both necessary and sufficient to guarantee a performance gap independent of the market size compared with networks with full flexibility, extending the previous literature from the long chains to more general sparse networks. Inspired by the performance bound, we develop simple inventory allocation rules and guidelines for designing such network structures. Numerical experiments including one using some real data from Amazon China are conducted to confirm our findings as well as some of the flexibility principles conjectured in the literature.

A Case Study Of The Environmental Impact Assessment Legislations In Sarawak, Malaysia

Environmental Impact Assessment (EIA) is a planning tool used to identify, predict, evaluate and mitigate the environmental effects of development projects. In Sarawak, EIA is governed by the both the State and the Federal EIA Orders. This leads to ambivalence in determining the legislation under which a prescribed activity demanding an EIA falls. This case study aims to investigate the implications associated with the coexistence of both EIA Orders in the state of Sarawak from the viewpoints of practicing environmental consultants. The case study reviews the EIA legislations governing EIA practices in the State and includes a qualitative survey involving practicing EIA consultants to gather feedback on the implications associated with the EIA practices and recommendations to resolve the problems identified. The study shows that even though a prescribed activity is defined by the EIA legislations, different stages of the prescribed activity eventually become prescribed activities on their own, which demand fulfillment of different EIA legislation. Unclear demarcation of EIA jurisdiction and different requirements on the scope of an EIA particularly for earthworks also contribute to doubts among environmental consultants interviewed. Consultation, involvement and effective communication with environmental protection as priority are crucial to minimize any uncertainty resulted from co-implementation of both the EIA legislations. Future study can look into comparing perceptions on the effectiveness of the State and the Federal EIA legislations. The case study delves into a crucial issue related to EIA practices in Sarawak, Malaysia which has persisted without being formally addressed in any previous studies.

Performance of obligations in modern civil law

The article considers the notion of performance. Treaty obligations were the most common in the civil turnover. Their performance depends to a large extent the stability of the economy and society as a whole. Of particular importance are norms of civil legislation implementing the Treaty obligation. They are used daily in practical activities of legal entities and citizens. The performance of an obligation – it is always a process that takes some period of time and consists of a series of actions of the debtor and the creditor. Debtor proposes the execution, the creditor accepts it. The article studies scientific approaches with respect to conditions of contractual obligations. practice shows that most contracts are careless, do not contain the necessary conditions to realization of the interests of the parties, do not include measures to ensure contractual obligations. During the execution of such contracts often have complications, different interpretations by the parties to the same conditions, and as a result, there has been a massive failure by the parties of their responsibilities, resulting in numerous conflicts. The most important task of modern legal science and practice – the creation of legal mechanisms, allowing most effectively to ensure the proper performance of contractual obligations and to compensate the injured party for the loss caused by their failure or improper performance. Mechanism of performance of the obligation is the mutual interest of the parties. In determining the obligations a list of specific actions that the debtor is obliged to make in favor of the lender, is limited to the indication of the transfer of property, performance of work and payment of money. Undoubtedly, the parties rely on bilateral compliance with the obligations under the contract, but obviously there are cases when under any circumstances one of the parties does not fulfill its obligations. Performance of the obligation should also be understood as certain acts by the debtor (or refraining from doing,) that is the obligation of the debtor. In this regard, it should be noted that the lender has the right to demand fulfillment of the obligation, but the debtor is involved in such actions. Moreover, under proper performance to understand the performance of an obligation by an appropriate person at the appropriate time a particular person under equal circumstances. The real is the performance of specific obligations, which is reflected in the implementation of certain actions.
