The presence of feed and its availability is one of the keys to the successful management of Trigona sp. The presence and availability of feed can be seen from the diversity of feed-producing plants (pollen, nectar, resin). Mirring Village is one of the villages in Polewali Mandar which has the potential for Trigona sp. This study aims to identify and analyze the diversity of feed sources for Trigona sp. in Mirring Village. This research is quantitative research with purposive method. The results showed that there were 42 types of plant sources for bee Trigona sp.  found in coastal areas as many as 3 species  with INP 88.99 – 102.30 and H' 0.99, residential areas there are 30 species with INP 3.15 - 56.20 and H' 3.1, and in mountainous areas there are 18 type with IN 4.77 – 47.22 and H' 2.40. Based on the results for residential and mountainous areas, it is sufficient to provide a source of food, while the enrichment of plant species diversity as a source of food for Trigona sp bees is best carried out in coastal areas

Food security is one of the efforts to create people's prosperity, related to this, the role of various sectors is needed to contribute in national food security programs. Every region has a community forest that produces food to meet the needs of its people. So far, information regarding forest food in West Sulawesi is still very minimal. This study provides information about the potential of community forests as food producers in Paku Village, Binuang District, Polman Regency. The time of the study was carried out from March to December 2018. This study used survey and interview methods for 12 respondents in locations that randomly plotted 20 x 20 meters. Data analysis using descriptive quantitative. The results of this study indicate that the potential of community forests in Paku Village in supporting good food needs, from community forests is able to produce 46.01% of food commodities consisting of 12 types of food based on the form of agroforestry. Some dominant types of food are sugar palm (Arenga pinnata), Cocoa (Theobroma cacao), Mango (Mangifera indica).

Public forests are land ownership whose management is oriented to timber productivity, but in addition to timber under stands can also be cultivated food crops and environmental services all of which have economic value. Community forest management can provide direct and indirect economic benefits as an alternative source of economic income for the people of Mirring Village, Binuang District, Polman , West Sulawesi. This research aims to find out how much the direct economic value of community forest based on its management system which can then be used as a reference for future forest management plan. The research was conducted from March to December 2017. Data were collected using survey and interview methods, where the observed variables included descriptions of community forests, community forest productivity including timber and non-timber forest products, and local market prices. The analysis is done descriptively quantitative. The result of the research shows the highest economic value is in agroforestry forest management system of Rp.127.962.157, followed by mixed stands  and monoculture system of Rp.97.894.958 and Rp.71.728.608, respectively. Products produced by community forests consist of timber and non-timber forest products.Keywords:  economic value, forest community, Polman.

The main raw material in the produce of palm sugar comes from boiling sap water which is taken from flower bunches from the extraction process and collected through the tapping process. In this industry, processing can be done in two ways, namely conventionally and modernly (using machines), the stages that are passed through these two methods are almost the same, the only difference being the tools used. This study aims to determine the palm sugar How to produce using conventional methods and modern, and find out how much effectiveness of making palm sugar with conventional and modern methods . This is a research descriptive quantitative . The results of the research show that the process of making palm sugar consists on four processes that cooking the sap of palm , crystallization , sifting and drying. the different process on the cooking sap and drying palm sugar. Indicators of the effectiveness of making palm sugar in each method are measured from the yield value , water content and production time. Percentage yield the highest generated from production is conventional amounted to 14,51 %. Value levels of water palm sugar that meet the standard ISO generated from production in modern amounted to 2,72 %. Time production by using the methods of modern is more concise than using methods konvensinal with a difference is 130 minutes.

Global warming is one of the major environmental issues of this century. Carbon dioxide (CO2) emissions are the main cause of global warming. Green open space (RTH) such as urban parks, urban forests and green lines play an important role in mitigating global warming and climate change in urban areas because it is able to reduce CO2 from the atmosphere. This study aims to determine the potential of biomass and carbon stored in the Green Open Green Space of Polewali, West Sulawesi. Data collection for stored biomass and carbon is carried out at three green space locations including; Urban forest and city park and green lane each made three plots measuring 20 m x 20 m, and three plots on the Green Line measuring 1200 m. Retrieval of data by measuring tree height and diameter, analysis to obtain the dry volume, biomass and carbon stored for each tree species contained in the Polewali green space. Biomass is obtained by the formula M = BJ x Vk x BEF, the stored carbon value is obtained from the product of biomass by 0.47. The magnitude of the relationship of volume with biomass and carbon uses a regression equation (Ŷ=a+bX). The results show there are types of Glodokan (Polyalthia longifolia), Johar (Senna siamea), Mahogany (Swetenia sp) and Trambesi (Samanea saman) which are spread in the Polewali open green space. Trambesi is a type that has dominant biomass and stored carbon of 381.95 (tons / ha) and 179.52 (ton/ha). Green lane is the type of green space that has the most stored carbon and is currently 440.94 (ton/ha) and 207.24 (ton/ha). The overall green space biomass is 571.83 (ton/ha) and stored carbon is 268.76 (ton/ha) found in urban forests, urban gardens and green belt. The relationship of volume with biomass and stored carbon shows a very strong relationship with the coefficient of determination (R2) of 0.96.
