National Interests are above International Affairs: Indonesian-Israeli Intelligence Operations on the Purchase of A-4 Skyhawks, 1978-1982
Get PDFThis study examines Operation Alpha, an intelligence operation conducted by Indonesia and Israel to facilitate the purchase and delivery of 32 Douglas A-4 Skyhawk aircraft from Israel to Indonesia between 1978 and 1982. Despite Indonesia's official policy of non-recognition towards Israel due to its support for Palestinian independence, the Indonesian government under President Soeharto pursued a pragmatic approach to address the urgent need for modernizing its aging military equipment. Through a series of negotiations involving the United States, Indonesia reached an agreement with Israel to procure the aircraft at a lower cost and with faster delivery compared to purchasing directly from the US. The successful completion of Operation Alpha not only bolstered Indonesia's defense capabilities but also marked the beginning of discreet military and economic cooperation between the two countries that continued until the reform era, despite the absence of official diplomatic relations. This study highlights the prioritization of national interests over international affairs in Indonesia's foreign policy during the Soeharto era and the role of intelligence agencies in facilitating clandestine cooperation between states with conflicting official stances

The historical method is used in this article to reveal various responses to Christian missions, ranging from traditional acceptance to integration into Christian traditions. This study also analyses how Dutch colonialism influenced the spread of Christianity, as well as the social, political, and cultural transformations that occurred. These findings offer a new perspective on the interaction between Christian missions, Batak customs, and colonialism in shaping the history of religion in the Batak region
Heritage Preservation of the Pulau Sawah Temple Complex in Dharmasraya Regency, Indonesia
Get PDFThe study focused on the preservation of the Pulau Sawah Temple complex under the management of Batusangkar Historical and Archaeological Heritage Conservation Agency (SPSP) Batusangkar to the Cultural Preservation Centre (BPK) III Region West Sumatra. The temple site had previously received inadequate attention, both from the community and the local government, even though it marked the heritage of the Buddhist Malay Kingdom. The situation improved when the SPSP was established and began operations, leading to increased attention and conservation efforts for the Pulau Sawah temple complex through various stages. Through primary and secondary source research, the study found that the conservation of the Pulau Sawah temple complex has involved numerous stakeholders. Various local stakeholders, supported by the Batusangkar SPSP as the precursor to the BPK III, have played a crucial role in the preservation process. Preservation efforts are not limited to collection management but are also supported by the management of the organisational structure of the institution responsible for the site complex. Therefore, the preservation of the temple structures on Pulau Sawah, which, when examined closely, can evoke the identity of Dharmasraya, is of great value and should be passed on to future generations
