Land conditions in Sungkai, Padang City, have slopes and high rainfall. The causes low water absorption capacity. For this reason, it is necessary to plant plants that can help increase water absorption, one of which is bamboo plants. This activity was carried out on November 6, 2021, to empower the community of farmer groups in the Andalas University campus with a focus group discussion on agricultural issues and planting bamboo trees. The activity consists of four stages: preparation, counselling/socialization, focus group discussion, and field practice. There are five main problems to solve. The issues found are 1) how to handle flooding in the river; 2) how to control plant-disturbing organisms without using chemicals; 3) new land clearing methods so as not to damage the environment; 4) how to obtain and treat good seeds and seedlings before planting, and 5) farmer group dynamics and their resolution. Planting bamboo is one of the steps to deal with the problem of flooding. Bamboo has a very tight, broad, and strong root system to strengthen the soil structure and withstand water runoff. Bamboo plants can also become new hosts of pests that damage cultivated plants. The service team synergizes with extension workers to understand bamboo, which can be an alternative in sustainably conserving soil and water.

Background: Whole genome sequencing is become an essential tool to explore potential of microorganism and evolutionary study. The Serratia plymuthica UBCF_13 is one of phylloplane associated plant bacteria showing antifungal activity. For that reason, its complete genome information is necessary to enhance its potential as biocontrol against plant pathogenic fungal. Here, we report the genome sequence of Serratia plymuthica UBCF_13 to understand the molecular mechanism regarding its biocontrol ability. Methods: Continuous short reads were attained from Illumina sequencing runs and reads 150 bp were merged into a single dataset. Pan-genome based method was used to identify core-genome of S. plymuthica species and unique gene in UBCF_13. Results: Assambled Illumina reads of S. plymuthica strain UBCF_13 genome was produced a 5.46 Mb circular genome sequence. It was found 3321 genes belong to the core-genome sheared by the 18 strains evaluated. The UBCF_13 genome harbor 485 unique genes, where 300 of them only can be found in this strain Conclusions: The sequence of UBCF_13 genome sequence data will contribute for further exploration of the potential of S. plymuthica UBCF_13 as bacteria producing antibiotic.

The main feed for ruminants is forage, and its supply fluctuates greatly depending on the season. During the rainy season, the forage will thrive and be abundant, but the opposite condition, i.e. dry season, where farmers will have difficulty getting fresh forage. Meanwhile, animal feed must be continuously available. The solution is to use agricultural waste as an animal feed with limiting factors, namely high lignin content, low digestibility, low protein content, and anti-nutrients. Therefore, a feed processing technology known as Ammoniation is needed. Ammoniation is a chemical treatment of agricultural and plantation waste feed ingredients by adding chemicals like NaOH, KOH, or Urea. Ammoniation can reduce lignin and silica and increase protein content. Socializing ammoniation technology in the Ambacang Permai livestock farmer group, Lima Puluh Kota District, was necessary. The method included lectures, demonstrations of making rice straw ammoniation, discussions, and consultations on animal feed. This activity was expected to help group members to overcome the problem of providing ruminants' feed from crop residues and plantation waste, so it was expected to reduce feed costs and increase group business.

Increasing the genetic diversity of plants can be done through physical mutations with gamma-ray irradiation. This study aims to determine gamma-ray irradiation on the growth of six M1 generation black rice accessions. This research was conducted in May-October 2019 at the Experimental Rice Fields of the Tasikmalaya Perjuangan University, West Java. The materials used in this study were six accessions from Tasikmalaya (PH, PH2, PH3, PH5, PH7, and PH8) without 0 Gy irradiation and with 200 Gy gamma-ray irradiation of M1 generation. The results showed that gamma-ray irradiation reduced germination characteristics, seedling height, and flowering age. Some of the accessions showed different effects; there were a decrease and an increase in the characters of root length, plant height, number of productive tillers, number of unproductive tillers, and the total number of tillers.
