Endophytic bacteria have been known to produce high levels of secondary metabolites. The sterile leaves of the sea fern (Acrostichum aureum L.) contain many phytochemical compounds. This sea fern is often found in peat swamp areas. The aim of this study was to isolate, partial characterization, and analysis of bioactive compounds from endophytic bacteria of sea ferns to determine their bioactive compounds. Endophytic bacteria were isolated by a direct technique using nutrient agar (NA) media. In this study, the endophytic bacteria were characterized by macroscopic, microscopic, and Gram. Several tests were further performed, namely phytochemical test and Fourier Transform Infra Red (FT IR) FTIR tests from a crude extract of secondary metabolites of bacteria. The results of the isolation obtained six isolates of endophytic bacteria consisting of all isolates were Gram-negative. The phytochemical test results for the six isolates were positive for alkaloids and saponins but no steroids. Based on the results of phytochemical tests and FT IR, it is suspected that the isolate DSB 1.6 has similarities with the alkaloid functional group. This endophytic bacterial isolate can be developed as a candidate for produced of pharmacological compounds.

Noodles are a processed food product favored by most Indonesians, generally made from wheat which must be imported. Kepulauan Meranti Regency is the largest producer of sago in Indonesia. One of the products made from sago that is widely produced in Meranti is sa.go noodle. Making noodles with local raw materials such as sago and sweet potato is an effort to improve food security. Traditional sago noodle has high carbohydrate and fiber content but still has disadvantages such as not having inulin content as a prebiotic, less antioxidant and a less attractive color, while purple sweet potato contains inulin as prebiotic components, high antioxidants, vitamins and minerals.The utilization of prebiotics insago noodle has multiple advantages since they improved probiotic growth in the body, sensory features and provide a more well-balanced nutritional composition as functional food. This community service program aims to training on the process of making prebiotic sago noodles to the community in Alai Selatan Village.This activities are carried out by course and practice methods.The results showed that the participants were interested in making prebiotic sago noodles because they had a more attractive features, more nutritious and had a delicious taste. Prebiotic sago noodles can be used as an effort to biodiversify sago noodle products to support food security and improve the community's economy.

Banana hump is one part of the banana plant that is still very rarely used. The Banana hump can be an item with a selling value because it contains high carbohydrates, fiber, and calcium to be an alternative food ingredient. The banana hump can be turned into nutrient-rich flour. Community empowerment to process banana hump into something useful and can be a pilot business for residents is one of the keys to this success of this activity. This service will provide benefits to various parties, including for community service participants, for the counseling implementation team, for universities, and for the government. The purpose of this activity is to introduce and train the skills of making flour made from banana humps, which we named "Tebosang" for the community of Balai Makam Village, Bathin Solapan District, Bengkalis Regency. The methods used include site surveys, interactive training preparation, mentoring, monitoring, and evaluation. Making flour from banana hump started with a waste of old banana hump, cleaned the surface, then sliced thin approximately 0.5 cm. The hump then washed and then soaked with whiting for about one hour, then rinsed and dried. The dried hump slices are then blended and then sifted so that they become flour. The community's enthusiasm was relatively high at the time of the training, shown by the community's involvement at the demonstration. The monitoring and evaluation results show that the community already understands how to make flour from the banana hump. The result also showed that the village community is already producing "tebosang" flour, which has commercial potential, a start-up for micro, small and medium enterprises in each community.

Endophytic bacteria are sized microorganisms found in plant tissues that are known to produce secondary metabolites, one of which is the ?-amylase inhibitor. Plant potential is closely related to endophytic microorganisms present in plant tissues. The study aimed to determine the potential of endophytic bacteria in rubber plants to produce ?-amylase inhibitors and to identify molecular using the 16S rRNA gene sequence. The isolates used were endophytic bacteria isolates L1M1.A2, L1M1.B4, and L2M1.A27. The activity of ?-amylase inhibitor was tested by in vitro and spectrophotometric measurements at a wavelength of 540 nm. Endophytic isolates with the highest inhibitory values ??were identified using the 16S rRNA gene sequence with primers 8F and 1492R. The results showed that the L1M1.A2 isolate produced 29.44% ?-amylase inhibitor and was identified as Bacillus proteolyticus with 99.86% homology. The potential of the L1M1.A2 isolate could be developed as a candidate for an antidiabetic drug.
