Introduction
Indonesia made significant economic progress in recent decades, yet preventable child illness and malnutrition remained persistent challenges. Pneumonia, diarrhoeal disease and undernutrition continued to contribute to avoidable morbidity and mortality, while disruptions during the Covid-19 pandemic left many children under-vaccinated.
In collaboration with the Government of Indonesia, Keluarga SIGAP was first piloted in Bogor (West Java) and Banjar (South Kalimantan). The pilot phase tested whether integrated messaging on immunisation, handwashing with soap and early childhood nutrition - delivered through existing primary healthcare platforms - could strengthen caregiver knowledge and household practices.
Early results from the pilot showed promising improvements in hygiene behaviours, immunisation confidence and nutrition practices. Based on these lessons, the programme was refined and scaled to three districts: Sukabumi (West Java), Brebes (Central Java) and Banjar (South Kalimantan), where vaccine coverage, hygiene practices and nutrition indicators required strengthening.
Programme overview
This unique programme - titled Keluarga SIGAP (meaning Ready Family) brought together a range of partners, each specialists in different sectors to create a truly holistic approach. Gavi, the Vaccine Alliance, led on the immunisation component, Unilever brought experience on sanitation and hygiene, The Power of Nutrition contributed via technical expertise on nutrition and finally, WPP Media as an implementing partner, used its experience in marketing to ensure the behavioural change elements create lasting impact.
During the scale-up phase, the programme combined community-level engagement with national digital and broadcast outreach. It aimed to strengthen demand for immunisation, promote handwashing with soap, improve early childhood nutrition practices and reinforce primary healthcare systems, particularly through Indonesia’s Posyandu network.
Programme interventions
Behaviour change communications
The programme delivered integrated messaging on immunisation, hygiene and nutrition through: Social media campaigns across Facebook, Instagram, TikTok and YouTube; National television public service announcement; Influencer and expert-led content; A WhatsApp-based digital tool providing reminders, quizzes and practical guidance. Between May and November 2025, digital content generated over one billion impressions nationally, reinforcing key behaviours beyond programme districts.
Gender equality
The programme promoted shared responsibility for child health by engaging fathers directly through community sessions and targeted messaging. Evidence from the scale-up phase showed increased male participation in hygiene and child health practices.
Community training
More than 6,000 community health workers were trained to deliver integrated counselling on immunisation, handwashing and child nutrition through home visits and Posyandu sessions, engaging more than 83,000 households. Local leaders, midwives and district health officials were also engaged to strengthen enabling environments.
Strengthening health systems
Keluarga SIGAP worked within government systems - particularly the Posyandu platform - to embed behaviour change messaging into routine maternal and child health services. The programme aligned with district planning cycles and explored pathways for integration into village and local health budgets to support sustainability.
PROGRAMME IMPACT
4.4%
increase in early initiation of breastfeeding
The programme noted a significant improvement in infant feeding practices - an independent evaluation showed a 4.4 percentage point increase in early initiation of breastfeeding in the target districts.
6.8%
increase in minimum dietary diversity
Proportion of children achieving minimum dietary diversity (foods received from at least five out of eight defined food groups during the previous 24-hour period) increased by 6.8 percentage points.
15%
increase in basic childhood immunisation coverage
Evaluation results showed a 15% increase in basic childhood immunisation coverage.
6.4%
increase in handwashing with soap compliance
Compliance across the six recommended critical handwashing occasions significantly rose by 6.4%.
While Keluarga SIGAP has concluded, its legacy lies in strengthened community platforms, trained health workers and a demonstrated model for delivering integrated immunisation, hygiene and nutrition messaging at scale. Discussions with district and national stakeholders explored pathways for sustaining elements of the model within routine planning and budgeting processes.
