Sungai Wain Protected Forest is one of the conservation areas in Balikpapan City which has an essential role in supporting the life of the city’s people.Currently, its existence is threatened due to the various activities and overlapping interests of stakeholders involved in managing the forest. Therefore, forest management that is supported by these stakeholders is urgently needed. This study aimed to identify the stakeholders involved and explain their influences, interests,and roles in Sungai Wain Protected Forest management.Data were collected through observation, interviews, and questionnaires. The respondents were selected using the purposive sampling method, and stakeholder mapping was used to analyze it. The results showed that the stakeholders classified as key players include the Balikpapan Protected Forest Management Unit (KPHL Balikpapan), the East Kalimantan Provincial Forestry Office, Pertamina UP V Balikpapan, and the NGO Foundation Pro Natura.Multi-stakeholder management could be an alternative model for managing the Sungai Wain Protected Forest to synchronize stakeholders’ interests. The KPHL Balikpapan could actas a leading playerand become a driving force in the Sungai Wain Protected Forest’s management efforts due to their appropriate main duties and functions. Hence, the coordination, communication, and cooperation between stakeholders could be well-formed to achieve the management objectives.Keywords: forest management, multi-stakeholder management, stakeholders, Sungai Wain Protected Forest

Abstrak: Peningkatan jumlah penduduk setiap tahun serta pertumbuhan ekonomi di Kota Balikpapan yang cukup tinggi memberikan dampak negatif terhadap lingkungan terkait pemanfaatan sumber daya air. Aktivitas manusia di kawasan hutan lindung telah menyebabkan degradasi dan deforestasi hutan lindung sehingga mengakibatkan sungai di dalamnya saat ini tidak mampu memenuhi kebutuhan air ketika musim kemarau. Penelitian ini bertujuan untuk menilai kelayakan air sungai di dalam hutan lindung Sungai Wain pada aspek kuantitas dan kualitasnya sebagai upaya penyediaan alternatif sumber air baku untuk pengembangan fasilitas perkotaan. Analisis sampel air dilakukan di Laboratorium Kesehatan Daerah, Dinas Kesehatan Kota Balikpapan. Hasil penelitian menunjukkan bahwa debit air sungai Wain sebesar 0,334 m 3 /dt , sungai Bugis sebesar 0,258 m 3 /dt sedangkan sungai Sengkuang sebesar 0,032 m 3 /dt. Kualitas fisik air dari ketiga sungai tersebut memenuhi standar baku mutu kesehatan lingkungan dan menunjukkan kualitas air baik. Kualitas kimia air pada umumnya menunjukkan nilai di bawah batas maksimal yang diperbolehkan kecuali parameter pH dan besi. Kualitas biologi air menunjukkan sungai Bugis
