Abstract. Syamsia S, Idhan A, Firmansyah AP, Noerfitryani N, Rahim I, Kesaulya H, Armus R. 2021. Combination on endophytic fungal as the Plant Growth-Promoting Fungi (PGPF) on Cucumber (Cucumis sativus). Biodiversitas 22: 1194-1202. Endophytic fungi are known to stimulate plant growth by producing secondary metabolites, including phytohormones (IAA and Gibberellins), siderophore, phosphate-solubilizing metabolites. In this study, a total of six endophytic fungi were successfully isolated from local rice plants and showed different abilities in producing secondary metabolites, during single isolates testing. These six isolates were then combined to obtain 15 combinations for analysis, to determine the best combination for application as a plant growth promoter. Subsequently, each combination was tested for phytohormones (IAA, gibberellins) and siderophore (quantitatively)-producing activity, phosphate-solubilizing ability, and the effect on cucumber (Cucumis sativus L) plant growth. F13 showed activity in producing IAA and produced the highest gibberellin levels, while F1 exhibited the highest phosphate-solubilizing activity. In addition, F11 (Na-salicylate) and F1 (catechol) showed the highest siderophore activity, while a combination of F6, F8, F9, and F12 successfully increased plant height growth. Also, F4 increased the root growth, while the fresh weight of cucumber was increased by F8 treatment, under controlled conditions. Molecular analysis showed the tested isolates have close similarity to Daldinia eschscholtzii, Sarocladium oryzae, Rhizoctonia oryzae, Penicillium allahabadense, and Aspergillus foetidus. The combination of endophyte fungal isolates showed potential as plant growth promoters, however, further testing on several plant types is required before the combination is to be widely applied.

PPUPIK Business Unit Muhammadiyah University Certified Plant Seed Production Center Makassar is a science and technology-based business unit that aims to develop campus entrepreneurship based on research results. The main product of this business unit is hybrid corn seeds, but in the process of producing corn seeds in addition to producing economically valuable corn seeds also produce corn waste which can cause problems if not handled. PPUPIK developed various waste corn compost products for the development of new business units. The production activities of various corn waste into compost products aim to make corn waste as a product of economic value and also as a place of practice for students in the application of science and technology and science-based entrepreneurial activities. The method of implementing the activity is divided into 5 stages, namely: 1) Production of various waste corn compost; 2) Analysis of nutrient content of compost; 3) Product label design; 4) Compost packaging; 5) Promotion and marketing of products. This activity involved students of the Faculty of Agriculture, the University of Muhammadiyah Makassar in the production, label design and promotion and marketing of products. The results obtained from this activity include; 1) students have experience in compost production, label design and product promotion and marketing; 2) the formation of a new business unit in PPUPIK activities; 3) produce economic value products from waste; 4) potential to get IPR.

Since the early 1970s, many farmers on the west coast of Indonesia have used groundwater to irrigate their agricultural land. Groundwater used is mainly done for rice, corn, and other secondary crops. As a result, the groundwater level in the area has experienced significant degradation and has also been followed by an increase in groundwater salinity. The government's suggestion to make artificial recharge with composter pipes or with "biopori" technology is considered difficult for farmers since they cannot afford to buy PVC pipes as their main ingredient. The challenge gave birth to our innovation to utilize local materials in the form of bamboo for artificial infiltration tools, which we call "bamboo-cavity." The three advantages of filling with "bamboo-cavity" are: (1) the ingredients are cheap and easy to obtain in the area of people's agriculture; (2) pollution-free because the material is without chemicals; and (3) easy to install because there is no need for soil drilling, where the bamboo is directly put in a hand hummer. This initial research was carried out with two objectives, namely: (1) Finding out the effect of "cavities" on the recovery of degraded groundwater; and (2) Knowing the effect of the number of inflection points on the rate of recovery of groundwater. The research was carried out by applying nine variations in the number of infiltration points, on agricultural land with topsoil characteristics that have low permeability. The results of the study provide an overview of the effectiveness of cavities as a means of enhancing, namely: (1) the effect of the number of cavities on increasing groundwater levels is very significant. The results of field observations found that the total increase in groundwater level in wells with the formation of 8 cavities reached 75%, compared to the increase in groundwater level in the control wells and the more installed cavities, the higher the increase in groundwater that occurs; (2) The test wells with the highest value of additive effectiveness are wells with a number of cavities between 56 and 64 points of infiltration, i.e., the recharge effectiveness reaches 3.74.
