Abstract

This study examines marketing system of rice, emphasizing on horizontal and vertical integration of paddy and rice, both at regional and world market. The study also anlyzes price stabilization pf appady at farm level and rice at consumer level, and examines domestic buffer stocks managed by rice. Econometric metdhos of vector autoregressive (VAR) and vector error correction model (VECM) are emplyed in this study. The results show that marketiung system of rice in Indonesia is very straightforward, involving commodity flow from paddy farmers, collector traders, rice millers, wholesalers, distributors, retail traders, and rice consumers. Rice markets in five major regions in Sumatra, Java, Kalimantan, Sulawesi, and Bali Nusa Tenggara showed horizontal market integration during the New Order regime (1968-1997)m albeit not in full integration. Rice markets were segmented during free-trade period (1998-2000), and during a managed-open market period (2001-2004). Vertical integration between paddy and ricve market only occurred during the New Order. Also, during that period, paddy price was relatively more stable than rice price in all three regimes. The study suggests that regulation in rice import should be continued, and policies on production improvmenet, land reform, and food diversification deserve more budget allocation. The government should develop regional price procurement system and strengthen rice buffer stock at regional level.

Abstract

The issue of violence against wife physically and psychologically, today more frequent in the community. The factual reality shows that domestic violence against wife is a phenomenon that sometimes considered to be prevalent in society. The common assumption must not be separated from social construction in the society that the husband is the head of the family and has full authority to the family members, including his wife. In that context, this study attempts to analyze how the concept of the women protection as victims of domestic violence in Islamic law. In the context of the protection of women in the household, the texts of the Quran give many answers that require embodiment household with ma'ruf relationship in the sense of equal, fair and democratic. It is confirmed that Islamic law carries a mission ofprotection, which is a mercy for all human beings on earth. It also harmonized with applicable laws protecting women in Indonesia today.Persoalan kekerasan terhadap istri secara fisik maupun psikis, dewasa ini semakin sering terjadi di masyarakat. Realita tersebut secara faktual menunjukkan bahwa kekerasan dalam rumah tangga terhadap istri, merupakan suatu fenomena yang terkadang dianggap lazim di lingkungan masyarakat. Anggapan lazim ini tentunya tidak terlepas dari konstruksi sosial yang berkembang di tengah masyarakat bahwa suami adalah kepala keluarga dan memiliki otoritas penuh terhadap anggota keluarga termasuk isteri. Dalam konteks itu kajian ini berupaya mengupas tentang bagaimana konsep perlindungan terhadap perempuan korban KDRT dalam hukum Islam. Dalam konteks perlindungan perempuan dalam rumah tangga,teks-teks al-Qur’an memberikan banyak jawaban yang mengharuskan perwujudan hubungan rumah tangga secara ma’ruf dalam arti setara, adil dan demokratis. Hal ini menegaskan bahwa hukum Islam membawa misi perlindungan, yaitu sebagai rahmat bagi seluruh manusia di muka bumi. Hal ini juga diharmonisasikan dengan hukum perlindungan perempuan yang berlaku di Indonesia saat ini.

Abstract

Global economic policy dominated by the influence of the Washington Consensus during the past few decades has led to many upheavals in the global economic order. The term Washington Consensus is associated with three major institutions located in Washington, the World Bank, the International Monetary Fund (IMF), and the US Treasury Department, and it has become a neoliberal economic agenda also called as the western economic agenda. The debates are increasing significantly regarding the effectiveness of policies that are sourced from the World Bank, IMF and the US Treasury Department in encouraging development. Where in reality, those countries that adopt the recommendations derived from the Washington Consensus, mostly bring them to experience economic problems. The last example is believed to be the 2008 global financial crisis.In this journal, the author will explain and analyse the definition and the recommendations offered by the Washington Consensus in order to promote global development. It will also present various criticisms that have emerged from the various parties to the Washington Consensus. Various analysis will also be given to understand that the Washington Consensus is already less suitable and appropriate for use to encourage the global development today. Then this journal confirms the need for a new reform of the global economic order, namely with the policy recommendations for the new global economy through a new consensus. The rapid development of globalization has changed characteristic of many countries, especially developing countries, so that many developing countries begin to look for new formulas to boost their economies. Because the Washington Consensus is seen only benefit developed countries, while developing countries and least developed countries are experiencing a lot of problems of development. Thus, due to the demand and push for a reformation of the global economic order, China and the countries of the region have established the Asian Infrastructure Investment Bank (AIIB), based in Beijing, and it is now often called as the Beijing Consensus. Then, it now becomes a real sign of resistance to the Washington Consensus.
