Abstract

The idea of governance has successfully gained its popularity in Indonesia. The government, private enterprises and society welcome and embrace the idea of governance as a final solution to maintain development. In this paper, it is argued that the implementation of governance can not guarantee the fulfillment of society’s interest due to the existence of unequal power relation embedded in country’s political environment. The concept of Governance, moreover, can be claimed as an imperialist instrument since this concept has strong interconnection with neo liberal agenda. Indeed, Governance as new imperialism will reduce nationalism. Key words: Governance, Hegemony, Nationalism, Imperialism.

Abstract

State Law No. 12/92 on agricultural systems for food crops stated that good quality seeds is seeds of correct and pure variety with high genetic, physiological and physical qualities, and in accordance with the quality standard of its class. The demand for groundnut seeds were almost entirely fulfilled by informal seed supply, which may come from a traditional system (farmers use their own seeds), buying from agricultural shops that process their own harvested pods into seeds, or buying from informal seed growers. Whilst the certified seeds produced by official seed growers is very limited in amount and supplys only a small portion of the total national seed demand. Under such condition, selection for seed quality is mainly based on the physical seed condition, such as seed size, brightness of seed coat color, and maturity of seeds. In other words, farmers prefer to select sound mature kernels and reject the shriveled kernels. Research results, however, indicated that plants generated from shriveled kernels were not significantly different to those generated from pithy kernels in term of growth and pod yield. Given the high cost and limited stocks of seed during the high planting season, it is advisable seed sorting process is not too tight and the use of wrinkled seeds for planting is prioritized. When there are overstock seeds, it is suggested to keep the sound or pithy seeds or to consume these seeds for food safety issue. This is because research results showed that shriveled seeds are more susceptible to Aspergillus flavus infection and aflatoxin contamination than the pithy seeds.

Abstract

Abstract This paper endeavors to review the inter-state relation in Southeast Asia countries. Especially in government policy. The most significant problem in regional relationship is about the absence of political awareness. As a consequence, ASEAN only provides limited positive achievement in political performance regionally. This article provides an alternative explanation for the limited achievement in political performance of ASEAN by assessing the implication of using non-interference principe to the incidence of ignorance and disconnection between ASEAN countries that leads to lack of political awareness. In this paper, we try to propose a combination between formal diplomacy actions done by state institution  and informal diplomacy actions done by non-government actors. We also points out an alternative strategy to promote political awareness on the future of SEA community. First, open policy to connecting diplomatic based community. Second, optimalize the regional cooperation with more concern with democracy and human rights issue. Third, building and institutionalizing political awareness through people participation. Keywords: regional cooperation, non-interference principal, political awareness, comunitarian

Abstract

Kenaikan permukaan laut global meningkat sebagai akibat dari perubahan iklim yang ditunjukkan oleh ekspansi panas laut dan pencairan es, termasuk di Indonesia. Hal itu diidentifikasi sebagai salah satu faktor yang paling berkontribusi yang mengancam masyarakat pesisir, seperti di daerah penelitian ini di tiga dusun Kecamatan Jabon Kabupaten Sidoarjo yang dilanda Banjir Rob akhir tahun 2017. Banjir tersebut dilaporkan membuat kerugian total minimal 5 miliar rupiah sehubungan dengan gagal panen rumput laut serta ikan hilang dalam produksi sebulan. Tujuan dari penelitian ini adalah untuk menganalisis kejadian Banjir Rob dan mengetahui pemilihan konstruksi yang tepat. Metode yang digunakan dalam penelitian ini menggunakan data primer dan sekunder, yaitu Unmanned Aerial Vehicles menggunakan Drone, pemanfaatan data angin 16 tahun dan data pasang surut. Metode penelitian ini membutuhkan Drone untuk mengambil gambar yang nantinya akan diproses menggunakan Software ArcGis dan Menci menjadi peta batimetri dan topografi, sementara data kecepatan angin menjadi Wind Rose untuk memprediksi tinggi gelombang. Hasil dari penelitian ini menunjukan bahwa daratan pada daerah penelitian memiliki ketinggian yang rendah dan ada endapan tanah pada dasar sungai, ketinggian permukaan air laut mencapai 15 mm/tahun. Untuk mengatasi masalah tersebut seharusnya dilakukan pengerukan pada dasar sungai dan pembuatan konstruksi tanggul di sekitar pesisir pantai.

Abstract

Stunting has become a global concern. The incidence of stunting globally contributes to 15% of under-five mortality, with 55 million children losing their health (Bhutta, 2013) and it is estimated to reduce the country's GDP level up to 7% (Galasso and Wagstaff, 2018). In Indonesia, the incidence of stunting has become one of the main health problems that needs to be solved immediately. Malang Regency is one of the districts in East Java Province that has received the spotlight regarding the problem of stunting. It is estimated by the Regent of Malang Regency that there were 30,323 toddlers from a total of 154,188 toddlers in Malang Regency who are stunted (Plenary Meeting of the Malang Regency DPRD, 2018). This stunting rate in 2018 generated confusion because based on data from the Malang Regency’ People Representative Assembly (DPRD), since 2017, Malang Regency has had no stunting problems as a result of the implementation of the Contraceptive for Women at Risk (CONTRA WAR) program and the Community-Based Integrated Epidemiological Surveillance program (SUTERA EMAS). This research was conducted to examine risk factors of stunting in Malang Regency through Geographical Weighted Regression (GWR). GWR was carried out to calculate the correlation between predetermined demographic variables (population density, education, early marriage), health variables (number of health facilities, number of health workers, access to health facilities, availability of clean water and sanitation, number of malnutrition) and economic variables (income, numbers of poor population, prosperous rice distribution) which are assumed to have an influence on the incidence of stunting.
