Abstract

The health of the teak tree can be affected by damage caused by pests and environmental factors. This study aims to determine the health of the teak tree in teak production forest areas at RPH Sukorame KPH Mojokerto, East Java, Indonesia. The method used was the forest health monitoring (FHM) method. The sample was chosen by using a cluster plot system with a total sample of 216 teak trees. Parameters observed were symptoms of damage and its causes, type of damage and damaged parts of the teak tree, height and diameter, tread quality, and tree health analysis. The results showed that the health level of the teak tree in the teak production forest area of RPH Sukorame, KPH Mojokerto, East Java, was included in the health category with a Cluster plot level index (CLI) value of 4.36 - 4.51. The damage to the stand was caused by the attack of armyworm (Hyblaea puera), termites (Schedorhinotermes sp), and other factors. The productivity level of the area could have been more optimal, with a branch-free stand height of 0-5 m and a diameter of 16-20 cm: grumusol and grumusol sandy soil with a pH ranging from 5.8 to 7.0. Forest management is needed so that the teak tree can achieve optimum productivity.

Abstract

Management of community forests using an agroforestry pattern based on porang (Amorphophallus oncophyllus Prain) plants can increase community income. Porang is a tuber plant from tropical areas that belongs to the potential Araceae family, but its product has yet to be well known. The research objective is to analyze the potential of the porang plant (A. oncophyllus Prain) on farmers' income. The benefit of this research is information for the people of North Lombok on the sustainable cultivation of porang plants and, simultaneously, maintaining local science in the region. The research method uses qualitative descriptions through observation/interviews with porang farmer respondents in Rempek Darussalam Village, North Lombok. The research results show that cultivating porang plants with agroforestry can be sustainable. The porang plant as local wisdom in North Lombok is also an effort to maintain local scientific or ethnoscience. The research results also show the economic potential for porang farmers. The average income of porang farmers is 64,927,885 (IDR) /year/hectare. A viable porang farming business planted under the stands of sengon (Falcataria mulucana (L) and can contribute to an income R/C Ratio of 8.11%.

Abstract

Agroforestry has been widely practiced by forest farmer groups in forest-edge areas; however, its contribution to household food security and product diversification is often not optimally developed. This community service program aimed to strengthen agroforestry-based food security and livelihood diversification at KTH Pujon Hill, Malang Regency, through the integration of food crops, coffee, and medicinal plants. The program was implemented using a participatory approach involving socialization, training, technology application, and continuous mentoring. Results showed that the integration of medicinal plants into existing agroforestry systems improved land-use efficiency, enhanced farmers’ knowledge and skills, and encouraged simple value addition through herbal beverage processing. Agroforestry practices at KTH Pujon Hill contribute to household food security by ensuring food availability, supporting income generation, and improving microclimatic conditions for crop production. The program highlights the potential of agroforestry-based community empowerment to support sustainable livelihoods and food security in forest-edge communities when supported by continuous assistance and institutional strengthening.

Abstract

The slope of the land can influence accessibility, water movement, and soil characteristics, thereby affecting the productivity of agroforestry plants. This study aims to analyze the effect of land slope on agroforestry productivity. The methods employed included field observations and questionnaires to collect data. A total of 100 farmers from various locations participated as respondents in this study. Regression analysis was conducted to determine and compare the influence of land slope on the productivity of agroforestry crops. The results of the analysis indicated that land slope does not significantly affect land productivity. The highest net income for farmers on slopes of 15-30% was from chili crops, amounting to Rp 76,987,600 per year with a B/C Ratio of 2.97, while the lowest was from cauliflower crops, with an income of Rp 31,586,800 per year and a B/C ratio of 1.74. The distribution of plant species across different slope levels was relatively uniform. Thus, the slope of the land does not have a significant effect on the success and productivity of the agroforestry system.
