For ecologist Elizabeth Linda Yuliani, the rich ecosystem of Lake Sentarum National Park in West Kalimantan is highly enjoyable because the surrounding provides breathtaking views to explore. As visitors to Lake Sentarum, Linda and her fellow researchers stayed on a houseboat, called motor bandong by locals. Living on a houseboat, Linda could observe eagles flying, orangutans and other wildlife. The researchers also observed and interacted with the local people, many of who made a living by fishing. Residents generally started their daily activities at 4 a.m., when they went to the lake for fish.
