The pressures of population, economics and politics have contributed to natural resources’ exploitation and land degradation including forestry. Generally, forest management in Java is carried out by the Forestry State Enterprise (Perum Perhutani). Joint C ommunity Forest Management (PHBM) is a program initiated by the Ministry of Forestry that involves the community in managing forests. The program was intended to reduce forest destruction and conflicts with communities, particularly in Java. One of the pro grams was implemented in Konto Watersheds, Malang, East Java that are covered two sub - districts, Ngantang and Pujon. However, PHBM program in Konto watershed was considered unsuccessful due to illegal logging, encroachment and forest fires. The objectives of this research are: (1) to analyze factors influence the successfulness of PHBM program, (2) to analyze factors influence community knowledge of PHBM Program. Field observations, interviews with households and a literature study were conducted to collect data. We used multiple linear regression analysis to reveal the factors influencing success and binary logistic regression analysis to reveal the factors influencing farmers’ knowledge. The results of this research were that the factors influencing succes s were the husband and wife’s perceptions, household income, manner of get land from Perhutani (buying or inheritance and share cropping) and age of respondent. Perceptions of PHBM were influenced by income, formal education, secondary jobs, extension serv ices and the wife’s knowledge of the program
