Abstract: Strychnos ligustrina Blume is one of the potential plants for medicine that has been used by the local community in Indonesia for traditional medicine. Some studies showed that S. ligustrina parts had different activities, such as antimalarial, antibacterial, antimicrobial, antioxidant, and anticancer activities. Triterpenoids, phenolics, tannins, alkaloids, and flavonoids were detected in this species. Different plant parts and grow sites may affect the composition of chemical components. Therefore, the present study investigated the chemical components in different parts of S. ligustrina from some grow sites. The chemical components of different plant parts were analyzed by GC-MS and showed 51 compounds in total. The major constituents identified as mome inositol, heptadecene-(8)-carbonic acid-(1), palmitic acid, quinic acid, and stearic acid. The main active constituent of the antimalarial drug, strychnine, was also detected in this study. The PCA and cluster analysis of chemical components resulted in distinguished plant parts into three groups, whereas had shown no difference among the sites. In addition, the crucial compounds of this species that potential for antimalarial, strychnine, are only found in the leaf and stem. It has been shown that the leaf and stem are potential plant parts for the antimalarial agent.

Abstract: Involving the community is one of the initiatives to promote the national achievement of emission reduction targets. Social forestry with agroforestry systems can establish in the forestry sector to help reduce carbon emissions. In the Forest Area with Special Purpose (KHDTK) Rarung in Central Lombok, carbon storage calculations have been performed for various agroforestry patterns created in partnership. The carbon storage analysis was carried out in four agroforestry patterns: coffee, vanilla, bamboo, and annual crops. The carbon stock of each agroforestry pattern was measured three times on a 20 x 20 m 2 plot. The three carbon pools examined were soil, vegetation, litter, and understory carbon. The results showed that a partnership agroforestry pattern is a form of carbon farming that can be widely developed. The bamboo agroforestry pattern has enormous potential for carbon storage.

Abstract: One of the success indicator of private forest farming is an increase in farmers’ income, which is indicated by the large contribution of income from private forests. The size of the income is influenced by several factors, including the pattern of private forest management which will determine the quality products of private forests. However, currently, most of the private forest farmers have not placed the aspect of land management as the main factor determining the success of farming in private forests. This research is conducted to determine the role of land management on the income of private forest farmers in Central Lombok Regency. The research was conducted in three private forests in Central Lombok Regency, namely Pemepek, Setiling, and Sepakek Villages. The method used is interviews using questionnaire to 45 respondents who are selected purposively. The object of observation is land management which include plant maintenance, and harvesting and farmers’ income from private forest and non-private forest. The data analysis was carried out in a descriptive qualitative manner. The results showed that in general, land management carried out by private forest farmers had not been able to increase income from private forests. However, farmers who carry out crop maintenance in the form replanting are able to produce a higher income than when farmers applied other land management activity. The combination of land management activity will improve their income. The more intensive land management, the higher the income will be obtained.
