Terrorism and conflict in early Reformasi Indonesia, including the 12 October 2002 Bali bombing, the response to Jemaah Islamiyah, the Aceh insurgency, the December 2004 tsunami, and the 2005 Helsinki Memorandum of Understanding

What this dot point is asking

NESA expects you to explain two parallel security stories of the Reformasi period: the development of effective Indonesian counter-terrorism in response to Jemaah Islamiyah's bombings (Bali 2002, Marriott 2003, Australian Embassy 2004, Bali 2005), and the political resolution of Indonesia's longest-running separatist insurgency in Aceh through the 15 August 2005 Helsinki Memorandum of Understanding. Strong answers integrate both narratives.

The answer

Jemaah Islamiyah

Jemaah Islamiyah (JI) emerged from the Darul Islam movement of the 1950s. The group was reorganised in Malaysia in the early 1990s by Abdullah Sungkar and Abu Bakar Bashir, both veterans of New Order Islamic dissent and Afghanistan-era international networks. JI sought an Islamic state stretching across Southeast Asia ("Daulah Islamiyah Nusantara").

The group's operational wing, sometimes labelled Mantiqi I or the "Karachi Six," planned multi-stage attacks. Imam Samudra (Abdul Aziz), Amrozi bin Nurhasyim, Ali Ghufron ("Mukhlas"), and Ali Imron formed the Bali operational team. The bomb-maker Dr Azahari Husin and Noordin Mohammad Top (both Malaysians) provided technical expertise.

JI had carried out the Christmas Eve 2000 church bombings across Indonesia (around 19 dead) without strategic effect. The October 2002 Bali operation was deliberately international.

The Bali bombing, 12 October 2002

At around 11:08 p.m. on Saturday 12 October 2002 on Jalan Legian in the Kuta tourist district, three bombs were detonated.

A small explosive carried into Paddy's Pub by Iqbal (the suicide bomber) detonated first, driving panicked patrons into the street. Twelve to fifteen seconds later, a 1,000-kilogram bomb in a Mitsubishi L300 van outside the Sari Club opposite detonated, killing those who had emerged. A third, smaller bomb exploded outside the US Consulate in Renon, Denpasar; it caused no casualties.

The Sari Club and Paddy's Pub were destroyed. The death toll, finalised over weeks, reached 202: 88 Australian citizens, 38 Indonesians, 24 British, 9 Swedish, 7 American, and others from 19 further countries. Over 200 were wounded, many with severe burns; the Royal Darwin Hospital received many of the worst cases.

The Indonesian response

The bombing tested President Megawati's slow response style. She had initially been reluctant to acknowledge a domestic Islamist terror problem; the scale of the Bali attack changed this. Perpu 1/2002 and Perpu 2/2002 (later passed as Law 15/2003 and Law 16/2003) created anti-terrorism powers and applied them retroactively to Bali (a provision the Constitutional Court later struck down).

The Indonesian National Police, with substantial Australian Federal Police support (Australian Commissioner Mick Keelty led the bilateral cooperation), built Detasemen Khusus 88 (Densus 88), a counter-terrorism unit within POLRI, on 30 June 2003. AFP, FBI, and CIA training and equipment followed.

Arrests came quickly. Amrozi was arrested on 5 November 2002 near Surabaya; Imam Samudra on 21 November 2002; Mukhlas in December 2002. They were convicted and sentenced to death by Denpasar District Court in 2003. After lengthy appeals they were executed by firing squad on Nusakambangan Island on 9 November 2008. Abu Bakar Bashir was prosecuted on lesser charges and ultimately released; he was later convicted in 2011 of supporting a separate training camp in Aceh.

Further JI attacks followed: the JW Marriott Hotel Jakarta (5 August 2003, 12 dead); the Australian Embassy Jakarta (9 September 2004, 9 dead); the second Bali bombing (1 October 2005, 20 dead). Densus 88 operations, including the killing of Dr Azahari in Batu on 9 November 2005 and of Noordin Top in Solo on 17 September 2009, dismantled most of the JI operational network.

The Aceh insurgency

Aceh, at the northern tip of Sumatra, had been a sultanate before Dutch conquest in the Aceh War of 1873 to 1903. Resistance to Indonesian central rule began with the Darul Islam revolt of 1953 and was reignited as the Free Aceh Movement (Gerakan Aceh Merdeka, GAM) declared by Hasan di Tiro on 4 December 1976.

The insurgency went through four phases. The 1976 to 1989 period was small-scale and rural. The "DOM" (Daerah Operasi Militer, Military Operations Zone) period from 1989 to 1998 brought heavy TNI deployment and systematic abuses; Komnas HAM documented several thousand killings and disappearances. The 1998 to 2003 Reformasi period saw failed humanitarian pauses (the December 2002 Cessation of Hostilities Agreement broke down). The 2003 to 2005 "Military Emergency" under Megawati saw martial law, around 50,000 troops, and an estimated 2,800 GAM and civilian deaths.

By 2005 the conflict had killed an estimated 12,000 to 20,000 over 29 years. The provincial economy, despite gas exports from Lhokseumawe, was depressed.

The 2004 tsunami

The 26 December 2004 Indian Ocean earthquake (magnitude 9.1 to 9.3, off northern Sumatra) and the resulting tsunami devastated Aceh. The death toll in Aceh and the offshore island of Nias reached around 167,000, with around 500,000 displaced. The provincial capital Banda Aceh and the western coast were destroyed.

International aid required local cooperation. Foreign militaries (the US Lincoln carrier group, Australian and Singaporean engineers) operated in the province. The TNI's effective control of the territory was diluted by international presence. Both Jakarta and GAM concluded that the conflict had to end.

The Helsinki Memorandum of Understanding, 15 August 2005

Five rounds of talks under former Finnish President Martti Ahtisaari ran in Helsinki between January and July 2005, mediated by Ahtisaari's Crisis Management Initiative. President Susilo Bambang Yudhoyono (elected October 2004) backed the process; Vice-President Jusuf Kalla and Coordinating Security Minister Widodo Adi Sutjipto led from Jakarta. GAM was represented by Malik Mahmud and Zaini Abdullah.

The Memorandum of Understanding was signed in Helsinki on 15 August 2005. Six core provisions: GAM would disband its armed wing of around 3,000 fighters; the TNI would withdraw all "non-organic" units to around 14,700 troops; Aceh would retain 70 per cent of natural resource revenue; Aceh could establish local political parties (the first time in Indonesian law); a Wali Nanggroe (Acehnese governor) figure with cultural authority would be recognised; and the Government of Aceh Law (UU 11/2006) would entrench the agreement.

The Aceh Monitoring Mission (AMM) under the EU and ASEAN supervised disarmament from September 2005 to December 2006. Around 840 GAM weapons were decommissioned; 26,500 TNI and POLRI personnel were withdrawn or relocated. Free elections in December 2006 produced Irwandi Yusuf, a former GAM intelligence chief, as Governor of Aceh.

The MoU has held. Aceh has not had a separatist insurgency since 2005.

Timeline

Historiography

Edward Aspinall (The Aceh Peace Process: Why it Failed and What it Achieved, 2005; Islam and Nation, 2009) is the standard work on GAM and the Helsinki process. He treats the tsunami as a necessary but not sufficient cause: both sides had reached strategic exhaustion before 2004.

Greg Barton (Indonesia's Struggle: Jemaah Islamiyah and the Soul of Islam, 2004) is the canonical account of JI, with biographical depth on Sungkar, Bashir, and Mukhlas.

Sidney Jones (International Crisis Group reports, 2001 onwards) produced the contemporaneous detailed reporting that mapped JI's structure.

Sara Davies and Luke Glanville (Protecting the Displaced, 2010) document the Aceh humanitarian dimension.

Indonesia's National Counter-Terrorism Agency (BNPT), established 2010, produces the official Indonesian assessment of counter-terrorism outcomes.

How to read a source on this topic

First, distinguish JI's strategic objectives from its operational reach. JI sought a regional Islamic state; it achieved tactical attacks. The Indonesian state's substantial Muslim population was never mobilised behind JI.

Second, weigh the tsunami carefully. It did not cause the Helsinki MoU on its own; both sides had already lost military momentum. But the international humanitarian presence in Aceh in early 2005 changed the political calculus.

Third, note the Australian dimension. The Bali bombing killed 88 Australians and produced an unprecedented level of Indonesia-Australia security cooperation. This is part of the Yudhoyono-era foreign policy story.

Common exam traps

Misdating the Bali bombing. 12 October 2002, not 11 or 13 October. The follow-up Bali bombing was 1 October 2005.

Confusing JI and GAM. JI is Jemaah Islamiyah, the regional Islamist terrorist network. GAM is Gerakan Aceh Merdeka, the Acehnese separatist movement. They have no operational connection.

Forgetting the tsunami's role. Helsinki was made possible by the post-tsunami political and humanitarian context.

Underestimating Densus 88. By 2009 the unit had dismantled most JI operational structures; it remains the most internationally respected element of Indonesian security.

In one sentence

The 12 October 2002 Bali bombing that killed 202 people, the construction of Densus 88 and the anti-terrorism legal regime in response, the December 2004 Indian Ocean tsunami that killed 167,000 in Aceh, and the 15 August 2005 Helsinki Memorandum of Understanding that ended the 29-year GAM insurgency together transformed Indonesia's internal security architecture in the early Reformasi years.
