Tomatoes are essential for Indonesians because they have high economic and nutritional value. In addition, as population growth increases, the demand for tomatoes also increases. Based on this, it is essential to research to predict the future development of tomato crop production. The research in this paper uses a dataset of tomato plant production in Indonesia, which is spread across 34 provinces in the last seven years, namely from 2015 to 2021), which is sourced from the Indonesian Central Bureau of Statistics and the District/City Agriculture Service of each Province. The algorithm proposed in this study is the Fletcher-Reeves Conjugate Gradient Algorithm which will be processed with the help of Matlab2011b. Research analysis with three network architectural models: 5-7-1, 5-13-1, and 5-17-1. Based on a network comparison of the three architectural models, the best result is the 5-17-1 model because the MSE value is the smallest compared to the other two models, namely 0.0009915 compared to 0.0010851 and 0.0049764, as well as the highest level of accuracy, namely by 94% versus 91% and 88%. Therefore the 5-17-1 model is used to predict the yield of tomato production in Indonesia for the future (2022 and 2023). Based on the prediction results at the end of 2022 and 2023, there are 18 provinces where tomato crop production has the potential to increase, although not too significantly. The prediction of tomato production using the Fletcher-Reeves algorithm is quite good because it produces a small error rate and high accuracy.

This study aimed at bolstering students' scientific literacy in biotechnology through the implementation of Experiment-Based Learning and Creativity Worksheets (LKPD). Utilizing a classroom action research framework, the investigation was conducted over two cycles, incorporating planning, action, observation, evaluation, and reflection phases. It involved 30 students and used observational sheets for monitoring teacher and student activities, along with multiple-choice and essay questions to assess students' scientific literacy. The findings revealed a notable enhancement in both teaching methods and student learning outcomes, facilitated by the LKPD usage. Specifically, teacher performance improved from achieving 80% of the set criteria in the first cycle to 90% in the second, upgrading their rating from 'Good' to 'Very Good'. This improvement was paralleled by a rise in students' average scores from 85.33 to 90.58, indicating a heightened engagement with and comprehension of biotechnological principles. The employment of LKPDs proved critical not just for expanding knowledge but for the practical application of scientific concepts, as demonstrated by an average literacy score of 88. Furthermore, an uplift in the average scientific literacy score from 76.59 in the first cycle to 84.89 in the second emphasizes the significance of LKPDs in enhancing students' grasp of scientific theories. Overall, the interventions across the cycles successfully elevated the caliber of teaching, enriched the student learning experience, and significantly improved science literacy, thus contributing to an enhancement in educational quality

Mangroves are one of the most important natural ecosystems. Mangroves physically function as land protection areas against the impact of abrasion and erosion due to waves. In terms of chemistry, mangroves act as filters for pollutants, especially organic materials, and as an energy source that provides detritus, which is a food source for aquatic organisms. Aquatic biota that live in mangrove areas include mollusks, crabs, fish, oysters, and shrimp. In addition, the role of mangroves is very significant in maintaining the productivity of waters in coastal areas and supporting the lives of surrounding communities. The purpose of this study is to identify biota whose lives are associated with mangroves of Avicennia spp. and Sonneratia spp. The method used in this study is exploration. The location of the transect is made based on the purposive sampling method, where data is taken deliberately based on the abundance of biota and mangroves of the species Avicennia spp. and Sonneratia spp. The types of biota associations Nerita polita, Turritella attenuata, Chicoreus sp., Mytilus edulis, Geloina expansa, Scylla tranquebarica, Leptuca uruguayensis, Aratus pisonii, and Lepas balanoides. Mangroves associated with the above biota are from the types of Sonneratia alba and Avicennia marina.

Abstract: Red chili is one of the crops commonly cultivated by farmers in several regions of Indonesia. This is due not only to its high economic value but also to its various health benefits. This study aims to determine the effect of applying different concentrations of NPK 16:16:16 fertilizer and goat manure liquid organic fertilizer (POC Kohe Kambing) on the growth of red chili plants. The experimental design used was a Randomized Block Design (RBD), while the treatment design was factorial, consisting of two factors: NPK 16:16:16 (N) with three treatment doses: N0: 0 ml/plot, N1: 60 g/plot, and N2: 120 g/plot. ,Goat manure liquid organic fertilizer (POC Kohe Kambing) with four levels: P0: 0 liter/plot, P1: 1 liter/plot, P2: 2 liters/plot, and P3: 3 liters/plot, each with three replications. The observed variables included plant height, the height of the first branch, stem base diameter, and the number of leaves. The results showed that the application of different doses had a significant effect on plant height, the height of the first branch, stem base diameter, and the number of leaves across all observation periods. NPK 16:16:16 influenced observations at 56 days after planting. The best results for goat manure liquid organic fertilizer were achieved at P3 (3 liters/plot). The interaction between NPK 16:16:16 doses and goat manure liquid organic fertilizer significantly affected all observed parameters.

Community service is an activity that realizes and improves the quality of community knowledge in helping the problems experienced by the community in the community. Through the Thematic Real Work Lecture (KKNT) program based on community service, this activity is to increase students' sense of solidarity with the existing conditions of the community. The use of land with hydroponic cultivation is an alternative that can be done by utilizing minimal yard land and being able to use used goods. Farming with hydroponics is very environmentally friendly in addition to not using pesticides, also the production can be used alone or as an economic source of household income. In addition, the outputs obtainedare n: (1) Improvement of superior quality of resources; (2) improving household economic resources; (3) Encourage the progress of the village. On the other hand, to ensure the discipline and participation of KKNT student participants and the community, by seeing the success in the form of outputs produced

Agriculture plays a significant role in economic development and food security in Indonesia, including in Air Joman District, which has great agricultural potential. However, various challenges, such as low productivity and limited access to modern technology, hinder the development of this sector. The community service program by the Faculty of Agriculture at Universitas Asahan aims to enhance farmers' capacities through the implementation of sustainable agricultural technologies. The methods used include counseling and practice-based training, such as utilizing household waste to produce organic fertilizers. Results showed an 85% improvement in farmers' understanding and a 20% average increase in crop productivity. The use of organic fertilizers also reduced production costs by up to IDR 500,000 per planting season, improved soil fertility, and generated additional income for farmers. This program not only provided positive economic and environmental impacts but also contributed to the sustainability of the local ecosystem, making it a replicable model for empowering farmers in other regions.
