Indonesia faces a food waste problem, particularly at the household level. Food waste causes negative impacts on several aspects such as environment, society, and economy. Ironically, at the same time, Indonesia also has a serious hunger problem. Through community development programs, we aimed to empower households in recycling their food waste by eco enzyme and their awareness through an online challenge. Eco enzyme is an affordable and useful method to recycle food waste being a liquid product with many benefits such as insect repellent, organic fertilizer, general cleaner, air purifier, and laundry cleaner. The total participants of the eco enzyme workshop were 57 people. On the other hand, through an online campaign #MelawanFoodWate, 101 users took action to be conscious customers in shopping behavior. These activities were in collaboration with several stakeholders to ensure the success of the program. These programs can be considered an initiation to develop Food Smart City that focuses on the community-based movement and circular economy.

Abstract. Afrianto WF, Wati SI, Hidayatullah T. 2021. The suitability assessment of the tree species in the urban parks and urban forest in Kediri City, East Java, Indonesia. Nusantara Bioscience 13: 131-139. Kediri has several urban parks and an urban forest as green open space (GOS) which have essential roles in economical, social, aesthetical, and ecological aspects. Generally, urban trees provide ecosystem services, such as carbon sequestration, stormwater attenuation, energy conservation, habitat for wildlife, air, water, and noise pollutants reduction. The present study aimed to (i) determine tree diversity in five urban parks and an urban forest of Kediri City and (ii) evaluate the suitability of tree species based on three indicators (silviculture, management, and aesthetic). This study was conducted in five urban parks and one urban forest in Kediri City. The suitability assessment was carried out through a literature review. The results showed that 29 tree species belonging to 17 families were found in the study sites, with the family Fabaceae being the most dominant one with five species. The number of exotic tree species (17) was higher than that of the native ones (12). The suitability assessment results showed that 21 tree species had a high score of 39-44, and only eight urban tree species had a medium score of 36-38. The urban parks and urban forests in Kediri were managed for the conservation of germplasm, recreation, and protection. The shapes were clumped and line. This study will contribute information to be used as guidance for urban tree management and policy framework.

Abstract. Afrianto WF, Tamnge F, Hidayatullah T, Hasanah LN. 2021. Local knowledge of plant-based nutrition sources from forgotten foods in Datengan Village, East Java, Indonesia. Asian J Ethnobiol 4: 53-64. Plant-based food has benefits for health and the environment. Finding adequate plant-based nutrition sources can be found by exploring local knowledge. Here, forgotten foods mean two definitions that (i) those foods were consumed by the community before, but over time it is forgotten in the daily diet, and (ii) unusually consumed by the community outside, but it still is or over-consumed by the community. This study aimed to identify the plant-based nutrition sources in Datengan Village. The study was conducted in the Datengan Village, Grogol Sub-district, Kediri District, East Java Province, Indonesia. Ethnobotany approach through qualitative research (i.e., observation, semi-structured interview, and participant observation) were used to explore the plant-based nutrient sources from forgotten foods in Datengan Village. The results showed forgotten foods in Datengan Village, i.e., fermented foods, mushrooms, by-products, and plant rich-nutrition. There were 26 plant-rich-nutrition, two mushrooms, two fermented foods, and six by-product foods. This investigation is still a preliminary study. 14 handling, processing, and serving methods were used based on the interview. This plant-based nutrition source diversity can be an alternative to fulfill nutrient requirements for the community of Datengan Village and the community of outside areas.

Solar panel/solar cell installation skills are needed at this time, not to mention the students. This is because fuel oil reserves have started to run low, and the government and world trends have turned to the need for new and renewable energy. Santri Nurul Jadid as a large Islamic boarding school in the Probolinggo area already has a Work Training Center (BLK) to equip the students when they have finished boarding. With the Electrical Engineering Study Program at Nurul Jadid University, it is necessary to provide technology transfer for students in the form of community service. The service is in the form of a PLTS installation in the form of a Solar Cell Umbrella Table.

Up to these days, many people globally have not yet realized the wondrous benefits of the drumstick tree (Moringa oleifera), such as citizens living in Kediri, East Java, Indonesia. Each person of the communities in the region mostly has spacious enough yards that can be optimized for drumstick tree cultivation. This community service aimed to (a) enhance motivation in gardening activities of urban communities; b) improve knowledge and skills of urban communities in cultivating, harvesting, and processing drumstick tree; c) increase greenery areas in the house; and d) improve food security and family health during the Covid-19 pandemic. Activities in the present community development were distributing gardening and education packages to the target community of Kediri citizens through online media ranging from planting, maintaining, and processing drumstick trees as a home industry business in order to enhance their income. Participants of these activities were also given some materials regarding the topic in the form of booklets and online collective assistance.
