This study aimed to determine the genetic diversity and fruits quality of the "Jeruk Bali" cultivars grown in Bali. This research was conducted in all regencies and city in Bali, during 2016. Furthermore, several cultivars of “Jeruk Bali” were genetically analyzed based on RAPD markers using 10 primers. Analysis of the quality of fruit is based on physical properties and chemical content. Eighteen cultivars of "Jeruk Bali" obtained have a fruit morphological character with round, short round, and piriform fruit shapes, which are red, pink, cream and white flesh color. RAPD analysis results at 53% similarity level are grouped into 5 groups. The first group was only one cultivar, the second group consisted of 13 cultivars, the third and fourth groups were only one cultivar, while the fifth group consisted of two cultivars. The analysis of the diversity between cultivars based on the combination of physical and chemical properties of the fruit with hierarchy method on similarity level about 85% in a group is obtained by 4 (four) groups. Groupings by combination of physical and chemical properties of the fruit are not synchronized in their entirety with dendograms based on their genetic diversity. This illustrates the physico-chemical properties of “Jeruk Bali” fruit in general is not fully genetical expressed, but also influenced by conditions of environmental growth.

Tourist villages will need infrastructure that supports tourism activities such as places to eat, places to stay, rest areas, galleries, and so on, one of whose goals is to improve the living standards of local people. This causes the number of plant species to decrease. Plant conservation by utilizing local wisdom is one of the efforts to reduce the decline in the number of plant species. Balinese people need many types of plants to support their ceremonial activities. The application of Tri Hita Karana and Tri Mandala in the daily life of the Balinese people is expected to support plant conservation activities and support tourism activities and provide economic benefits in the Pinge traditional village. The concept of Tri Hita Karana derives from the concept of Tri Mandala which consists of the main mandala as a parahyangan or holy place, Madya mandala in the form of a yard which includes residential buildings and natah, while nista mandala yard in the form of the back house (teba) and the yard of the front house (telajakan). Traditional Balinese gardening uses the concept of Tri Mandala. The problems raised in this "community service program" are still unorganized placement of plants in the Tri Mandala area and the lack of availability of plants for landscape management following the Tri Hita Karana concept. To support the management of landscape plants following the tri hita karana concept, Warmadewa University in collaboration with the Unda Anyar Seedling Nursery Center, Ministry of Environment and Forestry (KLHK) assisted plant seeds in the form of Cempaka seeds, avocados, sandalwood, majegau, jackfruit, rejasa, sawo, and soursop. Conducting webinars on the topic of landscape plant management following the tri hita karana concept. Inviting the people of Pinge Village to actively participate in planting Tri Mandala following the concept of Tri Hita Karana.

Among various flower varieties, chrysanthemum (Chrysanthemum sp.) is one of the most significant decorative flower commodities. Along with Aphis sp., which may do a great deal of harm, Thrips sp. pests pose a serious risk to chrysanthemums. Use of organic, non-toxic materials, such as plant-based biopesticides, is one substitute for managing Thrips sp. The purpose of this study is to ascertain which weed extract solutions, and at what doses, are most efficient at managing aphid pests on chrysanthemum plants. Two factors were included in the research design, which used a Factorial Randomized Block Design in a greenhouse setting: the type of weed extract solution and its concentration. Analysis of Variance (ANOVA) was used to examine the production data; at a 5% significant level, a Duncan or LSD test was then performed. The quality of the chrysanthemums was then compared to the Indonesian National Standard (SNI) 01-4478-1988. Aphid population, aphid mortality, flower diameter at full bloom, and percentage of flower damage (derived by dividing the number of damaged petals by the total number of observed petals) were among the observed variables. The findings showed that the chrysanthemums grown in the Ageratum conyzoides weed extract solution had the maximum growth and flower production, along with the lowest percentage of diseased leaves. Furthermore, the 300 grams/liter concentration demonstrated greater efficacy in impeding pest attacks, resulting in increased chrysanthemum development and a reduced proportion of leaf infection. For chrysanthemums to develop as best they can, the study advises applying a solution of Ageratum conyzoides weed extract at a dosage of 300 grams/liter.
