Dalegan Village of Gresik District, East Java, is a large Legen / neera and Palmyra fruit producing village. During this time legen siwalan was sold in the form of natural drinks. The problem faced by partners at this time is this Palmyra fruit spoils relatively quick so it doesn’t have high selling value. A technology is needed in the form fermentation to produce Nata de Legen using Acetobacter xylinum. Training method used were in form of lectures, demonstrations, discussions, direct practice, independent tasks, evaluation and marketing trials. The training was conducted in 3 groups consisting of 10 Local Welfare Organization (PKK) members and 5 Youth Organization members. The expected output target at the end of the program is that all participants succeeded in making the starter and Nata de Legen correctly. Participants also managed to whiten and soften raw Nata, which then made into end-products in the form of fruit-flavored Nata de Legen drinks (honeydew, strawberry, orange and cocopandan) and desserts in form of jelly and pudding packed in cup and bulk with the selling price calculated accordingly to Nata de Legen entrepreneurial training.

An ethnobotanical study in the Sumenep regency of Madura island has been carried out by observing nine locations, including the historical-religious tourism area and sacred places. This article described plant diversity, use value associated with local knowledge, and socio-cultural value associated with local wisdom. Totally 35 respondents were interviewed consist of primary respondents from each research area and typical respondents. Totally 31 plant species were found in study sites, covering cultivated and socio-cultural plants. Plant diversity was related to role of the location where they took place. Sumenep Palace, the main tourism area located in the center of town, reached the highest diversity of two socio-cultural and 18 cultivated plants as its domestication efforts to attract visitors. Ficus benjamina had the highest socio-cultural values as a usual dwelling for spirits and used to place some offerings, accelerate fortune and specific occasions. The local wisdom of Sumenep people directly related to how these plants can provide benefits, such as Manilkara kauki and Morinda citrifolia which were valuable as socio-cultural plants and fruit trees at once. Ficus benjamina which were valuable as socio-cultural plants related to local wisdom indirectly.

Water clover (Marsilea crenata Presl.) and water primrose (Ludwigia adscendens L.) are plants grow in wetlands, polluted by inorganic or organic materials, including detergent. This study aims to evaluate the capability of M. crenata and L. adscendens individually or as a consortium to remediate linear alkylbenzene sulfonate (LAS) detergent-polluted water, and to measure the growth and chlorophyll content of these plants. M. crenata and L. adscendens were grown in a hydroponic system exposed to LAS at 0, 10, 20, and 30 ppm for 10 days. Concentration of LAS (as anionic detergent) in treated media was analysed by UV-Vis spectrophotometer at 652 nm, wet biomass was measured using analytical balance, and chlorophyll content was analysed using spectrophotometer at 649 and 655 nm. Data were analysed statistically using analysis of variance followed by the Duncan test. The results shows that (1) at the end of experiment the concentration of residual detergent increased with increasing LAS in the media and (2) the plants biomass and the chlorophyll concentration decreased with increasing the LAS concentration in media. However, since both M. crenata and L. ascendens can significantly reduce LAS detergent concentration and can survive in 30 ppm concentration of LAS detergent, both species can be applied as phytoremediator agents.

Based on the results of the interviews, it was found that science teachers in Nganjuk Regency did not understand and master the skills of analyzing, especially with Biology material so that there was a need for training to practice analytical skills through optimizing learning. This training activity aimed to develop analytical skills through optimizing the learning process. This training activity involved 10 junior high school teachers who are members of  the Science Subject Teacher Association (Musyawarah Guru Mata Pelajaran/MGMP) of Nganjuk  Regency. The method used was observation and data were analyzed in descriptive qualitative. The implementation of the activities were divided into three stages, namely the preparation, implementation, and evaluation stages and feedback, as well as participant responses. The results of the responses based on the questionnaire were positive with a score of 3.82, very good training material at 3.82, and very good training conditions with a score of 3.84. There was an increase in the learning analysis skills of MGMP participants with a percentage of 82.40%.
