The Cucurbitaceae has been known to many farmers as a plant that has beneficial for agriculture industries. For decades plants that belong to Cucurbitaceae such as cucumber (Cucumis sativus), watermelon (Citrullus lanatus), and melon (Cucumis melo) has been cultivated to meet consumer needs. In Indonesia, a new variety of melon has been discovered namely apple cucumber. This new variety has blurred the difference between melon and cucumber due to the vegetative resemblance. This research was conducted to clarify the different characters and to study the morpho-agronomic characteristic in qualitative and quantitative-based on IPGRI descriptors. Important and significant diagnostic characters were observed to developed good cultivar in quality and quantity. 16 qualitative and 15 quantitative characters from 120 characters of apple cucumber were observed to determine the specific characters for good cultivar. Principal Analysis Component (PCA) using Python was used to showed discriminative character and also to distinguished apple cucumber to melon and cucumber based on 120 characters of apple cucumber. Morphological differences existing among melon, cucumber, watermelon, and apple cucumber, in particular, are presented.

Cucurbitaceae is one of the largest family in Angiosperm in which the most member of this family is important fruit crops in Indonesia such as Cucumber, Melon, Watermelon, and Apple Cucumber. In particular, Apple Cucumber, currently attracts attention to many researchers due to its phylogeneticand taxonomic problem. In term of its appearance, the fruit looks like an apple but the taste is melon. The purpose of this study was to elucidatephylogenetic relationship between Apple Cucumber and other species of Cucurbitaceae based on variation of DNA sequences derived from internal transcribed spacer (ITS) region. As many as six individuals of Apple Cucumber collected from Karawang, Jember, and Aceh were examined. The ITS sequences of some species of family Cucurbitaceae were retrieved from GenBank, and put them in the analysis. Phylogenetic analysis based on parsimony method with using Begoniaas outgroup reveals that Apple Cucumber are nested in the same clade as Melon (Cucumis melo) with high bootstrap value (100%), suggesting that Apple Cucumber is under the same species as Melon. However, on the basis of morphological characters of fruit, apple cucumber is different with that of Melon. This considerably first phylogenetics treatment provides fundamental knowledge for establishing a subspecies of Melon.

This community services activity was conducted together with a partner that is Benong II Farmers Group, in the Kalibuaya Village, Telaga Sari, Karawang. The problem that faced by partners is a lack of understanding of plant pest organisms (OPT), especially plant pests and diseases, as well as a lack of knowledge about the natural enemies. Knowledge and skills of the Benong II Farmers Group in the Kalibuaya Village, Telaga Sari, Karawang regarding the management and control of rice stem borer that environmentally friendly, especially biological control using parasitoid Trichogramma sp. needs to be improved. The evaluation results show that counselling and training on the breeding of natural enemies Trichogramma sp. resulting in the development and progress of the behavior, attitudes, and skills of farmers. There are four main results of the research. The results are (1) farmer more understand of the use of biological agents for IPM-based rice pest and disease control; (2) want to implement the control of rice stem borer Scirpophaga sp. by using Trichogramma sp.; (3) more skilled in monitoring the presence or absence of pests in rice plantations in the field; and (4) more active in finding out to community service teams, farmer group leaders, and POPT / field extension officers about how to mass culture theTrichogramma sp. and it's release techniques in the field.

This study is aimedto determined the effect of nutrient availability on growth andproduction 9 genotypes of rice in drought conditions. This study is an experiment of growth and production of rice genotypes with different nutrient availability in drought conditions using soil media in the pot. The design was Randomized Complete Block Design (RCBD) repeated three times. The factor that was (1) NPK fertilizer treatment with 2 levels of fertilizer and without fertilizer, and (2)9 genotypes of rice that was 3.

Onion production must always be increased. Liquid organic fertilizers affect the growth and development of soil microbes and the nutrients contained in POC will be absorbed more quickly by plants. Guano or swallow droppings originating from the swallow cultivator building are currently not widely used and further processed, even though the waste can be used as fertilizer that can fertilize plants. This study aims to obtain the POC dose of swallow droppings that provide the highest growth effectiveness and yield in shallot (Allium ascalonicum L.) plants.The research method used was a single factor Randomized Block Design (RBD), namely the dose of POC with 7 treatments that were repeated 4 times, namely treatment A (Without NPK and POC (control (-)), B (NPK 600 kg / ha (control (+)), C (POC 3 l / ha + NPK 300 kg / ha), D (POC 6 l / ha + NPK 300 kg / ha), E (POC 9 l / ha + NPK 300 kg / ha), F (POC 12 lt / ha + NPK 300 kg / ha), G (POC 15 l / ha + NPK 300 kg / ha). Data were analyzed using variance (ANOVA) and DMRT at the 5% level. Based on the results of the study, the dosage of swallow droppings POC did not have a significant effect on all components of growth and yield. This shows that POC made from swallow droppings has not been able to increase the growth and production of shallot plants.
