Abstract

Pioneer plants are plants with high adaptability, so they can grow in disturbed environments, such as ex-limestone mining areas. This adaptability is supported by the ability of these plants to associate with soil bacteria in their rhizosphere area. The presence of these bacteria can support the growth of pioneer plants on disturbed land. The purpose of this study was to characterize the soil bacteria around the rhizosphere of pioneer plants in the former limestone mining areas. Soil samples in the rhizosphere area of 5 pioneer plants from ex-mining lime were then isolated using the Pour plate method to obtain bacterial isolates. The bacterial isolates obtained were then identified their colony morphology. Based on the results of colony morphological identification, 21 isolates were obtained from the rhizosphere of 5 pioneer plants from the former limestone mining area. The highest number of isolates was obtained from the rhizosphere of the Waltheria indica with 9 isolates, 8 isolates of each Lamium barbatum and Digitaria sanguinalis, 7 isolates of Chromoleana odoratum, and 5 isolates of Tridax procumbens.

Abstract

Feed preparations are the most important thing in the field of animal husbandry. This activity is done every day and often takes a lot of time and effort, especially if done manually and to meet the needs of feed on livestock in large quantities. This obstacle is felt by breeders who are in the Kebonharjo Village Jatirogo district of the Tuban regency. To overcome this, it is necessary to conduct a Community Service program to hold feed kits for ruminant animals and provide knowledge in the efficiency of time and animal feeder personnel. Partners in this community service program are two farmers in Kebonharjo Village of Jatirogo District of Tuban Regency, with more than 15 cattle. In this program, the approach is to conduct direct observations and interviews to get data and problems faced by partners and to offer solutions that who will give to help partner problems. The solution provided by Tim community service is to hold an Electric and Portable Feed Countering tool (PPEP) so that the activities of providing animal feed by partners are more effective and efficient.

Abstract

Observation of leaves, especially the epidermis, is often the focus of research because this part is directly exposed to the environment, so changes that occur in this part can indicate changes in the plant's metabolism. Observation of leaf skin requires preparation in advance, especially in observing wet preparations. There are various methods of leaf skin sample preparation including the printing method and leaf paradermal slices. The purpose of this study was to compare leaf preparations with preparations using the printing method and paradermal slices carried out by students of the Biology at PGRI Ronggolawe University in the Plant Anatomy Practicum course. Data in the form of preparations of leaves Morinda citrifolia and Solanum melongen were observed using an electric microscope with a magnification of 400 times, while Ixora sp. leaves were observed using a light microscope with a magnification of 400 times. The results of the study can be concluded that the printing and paradermal incision methods are optimal for the purpose of observing different leaf characters. The optimal printing method is used on leaves that have little or no trichomes and is very good for observing stomatal openings. While the paradermal slice method is good for use on leaves that have trichomes or not, the use of this method requires good practical skills, besides this method cannot represent leaf stomatal openings at the time of observation because the stomata tend to close.
