Sengon (Falcataria moluccana) is a superior commodity of private forests in Java island. However, its management faces a gall rust attack. In addition, another challenge is the presence of weed disturbance which can reduce plant growth productivity. This study aims to measure the diversity and utilization of weed species in the agroforestry and sengon monoculture demonstration plots. The research method used was the method of vegetation analysis of understorey and interviews. Data analysis was performed descriptively using the importance species index, species diversity index and species similarity index.The results showed that both cropping patterns produced the same level of diversity and species richness despite differences in species density and presence. A total of 29 species of weeds were found in the agroforestry pattern and 27 types in the monoculture pattern.. Weed species diversity in agroforestry and monoculture patterns is classified as moderate with Shannon-Wienner species diversity index (H ') values of 2.47 and 2.66 respectively. Likewise, the level of species richness both pattern is classified as moderate with Margalef Richness Index (R’) value of 3.89 in monoculture and 4.23 in agroforestry. The level of species similarity between the two cropping pattern according to the Bray-Curtis Index is 0.66. The density of weeds in the monoculture pattern is higher (66.00 individuals / m2) than the agroforestry pattern (62.25 individuals / m2). Most of the weeds (67.65%) are used by people around the forest as animal feed (18 species), foodstuffs (4 species) and traditional medicine (4 species). The many species of weeds that can be utilized by the community shows that sengon forests can support food security, so that the weed control techniques recommended are manual techniques with simple tools and spatial management with F. moluccana plants.

Kombinasi jenis pohon dan tanaman pertanian pada sistem agroforestri dapat berpengaruh pada jenis dan intensitas serangan hama dan penyakit. Penelitian ini bertujuan untuk mengetahui persentase serangan dan intensitas serangan hama kumbang moncong pada dua pola agroforestri akor. Pengamatan dilakukan pada dua pola agroforestri berbasis akor, yaitu: akor ( Acacia auriculiformis ) + kacang gude hitam ( Cajanus cajan ) +padi ( Oryza sativa ) (Pola 1) dan pola akor ( A. auriculiformis ) + kacang gude hitam ( C. cajan ) + kacang hijau ( Vigna radiata ) (Pola 2). Jumlah sampel tanaman yang diamati adalah 30 pohon yang dipilih secara acak pada masing-masing pola. Parameter yang diamati adalah persentase serangan dan intensitas serangan hama kumbang moncong. Hasil pengamatan menunjukkan bahwa persentase serangan Hypomeces squamosus mencapai 100% pada pola 1 dan 96,7% pada pola 2. Intensitas serangan kumbang moncong H. squamosus pada pola 1 dan pola masing-masing sebesar 81,06% dan 6,21%. Lebih tingginya intensitas serangan H. squamosus pada pola 1 disebabkan adanya tanaman padi sebagai inang lain H. squamosus . Upaya pengendalian yang dapat dilakukan diantaranya pengelolaan ekosistem melalui rotasi tanaman padi dengan jenis lain yang bukan inang H. squamosus . Jika terjadi ledakan populasi hama maka digunakan pestisida nabati atau kimiawi secara selektif untuk mengembalikan populasi hama pada asas keseimbangannya dengan aplikasi ekstrak cabai rawit atau insektisida berbahan aktif acephate, carbaryl atau methamidophos .

The purpose of this study was to determine the weed density and the dominant species of weeds in Malapari ( Pongamia pinnata (L). Pierre) agroforestry. The study was conducted in Patutrejo Village, Grabag District, Purworejo Regency. The method used is single plot method in malapari agroforestry, as a comparison of observations of weeds on empty land that is not planted. Weed sample collection was carried out by the quadratic method measuring 1 m x 1 m as many as 3 plots placed in malapari agroforestry and empty land diagonally. Observations were repeated 3 times so that there were 18 observation plots. The results showed that weed density in malapari agroforestry (29.95) was lower than empty land (54.17). The dominant species of weeds in both malapari agroforestry and empty land is Eulalia amaura (Buese) with Important Value Index (IVI) of 36.40 % and 43.39 %. This species is a pioneer weed and fast growing, so monitoring and control are needed so that the weed population is not economically disserve.

Soil macro fauna is one of the bio indicators in determining the quality of the land. The total soil macro fauna is influenced by the climatice condition and land utilization pattern. Agroforestry is one of type land utilization that is expected to improve the soil fertility. Land utilization changing from monoculture into agroforestry is predicted to influence the soils macro fauna. This study is aims to find out the population of soil macro fauna before and after applying manglid agroforestry. The research was conducted in Cukangkawung, Tasikmalaya District, West Java Province. Sample of macro fauna was taken from non-productive land of tea plantations and one year after the land was planted by manglid + corn + peanut by using agroforestry. Samples were taken in Feb-March 2015 and once more in Feb-March 2016. The observation land area is 1 hectare that is divided into 1 m x 1 m - 16 observation plots that was placed randomly. In each plot, a hole of 30 cm in depth was made and the dug out soil was placed on the plastic container. The collected macro fauna was counted and placed into a bottle that was filled with 70% alcohol. The macro fauna identification was conducted in LIPI zoology laboratory. The research shows that the diversity indexes for Shanon and Margalef on manglid agroforestry are higher than on the ex tea land. Factors that influence the soil macro fauna diversity improvement is pH, low temperature of soil and high soil moisture. Soil macro fauna becomes organic decomposer in agroforestry for about 56,25% and 20% in non-productive land of tea plants.

Limited agricultural land areas combined with increasing demands for food require breakthroughs in land use development using agroforestry systems. Intercropping root crops with trees could be an alternative for food production in forest areas. This study aimed to assess the feasibility of cocoyam (Xanthosoma sagittifolium (L.) Schott) farming on dry land within 12- and 42-year-old teak (Tectona grandis L.f.) forests to support local food security. The feasibility assessment took into account both productivity and socio-economic aspects. The agroforestry land productivity was measured using the land equivalent ratio (LER), and our analysis of the cocoyam farming within the teak stands was carried out using the revenue/cost ratio (R/C) at the demonstration plot scale. Furthermore, we also surveyed farmers’ perceptions of the production of cocoyam for food security. The results showed that the R/C values of cocoyam tuber production in agroforestry systems were lower than 1. However, the production rates of cocoyam tubers in the 12-year-old teak stand (48.3% light intensity) and the 42-year-old teak stand (62.5% light intensity) were 2.64 and 2.76 tons/ha, respectively. The overall yields from the teak and cocoyam agroforestry systems were more profitable than those of the monoculture system, as indicated by the LER values of 1.61 and 1.85. Cocoyam production was socially acceptable (77% of respondents) as a smallholder subsistence agroforestry practice to meet food demand. Increasing cocoyam productivity in teak forests requires the adoption of agroforestry silvicultural technology to achieve food security for rural communities. To increase their farming production and income, farmers could apply intensive silvicultural practices. Governmental support that could be provided includes encouraging product diversification and providing assistance for the processing and marketing of cocoyam products.

Agroforestry has been practiced for decades and is undoubtedly an important source of income for Indonesian households living near forests. However, there are still many cases of poverty among farmers due to a lack of ability to adopt advanced technology. This literature review aims to identify the characteristics and factors causing the occurrence of agricultural subsistence and analyze its implications for the level of farmer welfare and the regional forestry industry. The literature analysis conducted reveals that small land tenure, low literacy rates, and lack of forest maintenance are the main causes of the subsistence of small agroforestry farmers. Another reason is that subsistence-oriented agroforestry practices are considered a strong form of smallholder resilience. All of these limitations have implications for low land productivity and high-sawn timber waste from community forests. To reduce the subsistence level of farmers, government intervention is needed, especially in providing managerial assistance packages, capital assistance, and the marketing of forest products. Various agroforestry technologies are available but have not been implemented consistently by farmers. Therefore, it is necessary to develop an integrated collaboration between researchers, farmers, and regionally owned enterprises (BUMD) to increase access to technology and markets. Although it is still difficult to realize, forest services, such as upstream–downstream compensation and carbon capture, have the potential to increase farmer income.
