The implementation of smart farming still uses AC electricity resources which is estimated to be less effective in its implementation due to wasted electricity costs. As well as the lack of a crop monitoring system by farmers, crop yields are not optimal. This research aims to produce a smart farming system that is used for hydroponic plants to monitor plant conditions periodically and the automatic watering process and nutrient measurements are more efficient, online to the network with the IoT concept, and saves energy by utilizing solar panels. This research is quantitative research with experimental methods. The stages in this system include flowcharts and block diagrams to make it easier to read the workflow that will be created and tested. The results of this research are that the monitoring system with the Blynk Smartphone application turns on if the pH sensor gets a result of 7.2 causing it to open and the pH solution drops in the solenoid which will make nutrients flow into the water container. The solenoid will experience a closed condition because the sensor gets results in the range of 6.2 to 7.2 in pH units. The water level gets an average height of 18.5 to 19.5 cm with the sensor, nutrients are filled into the water container when the solenoid is triggered and turns off when it gets to the maximum value limit. Solar panels as an energy source for detecting acid bases in pH units and hydroponic nutrients are proven to be able to operate all devices within 24 hours during the period of growth.

Food waste in urban areas is an endless problem, considering that waste will continue to exist. The technique of managing waste to become an alternative feed for catfish is one of the steps to overcome the problem of waste and at the same time becomes an alternative fish feed solution for fish cultivators. The purpose of this research is to process food waste into fish feed. The method used in writing this article is literature review. Based on the results of the literature review and the author's analysis, it can be concluded that food ingredients that can be processed into catfish feed are food waste by utilizing fermentation or by mixing or formulated with other raw materials such as (fish meal, magot, tofu dregs, and fine bran). The fermentation process can use fishery products sold in the market, including (EM4, Boster, etc) which are mixed with molasses.

Ikan mas koi merupakan ikan hias yang populer di kalangan penggemar akuarium karena memiliki nilai budaya yang kaya. Salah satu aspek terpenting dalam menjaga kesehatan ikan koi adalah kualitas air akuarium. Kesehatan dan pertumbuhan ikan dipengaruhi oleh faktor-faktor penting seperti suhu, pH, kadar oksigen terlarut, dan ammonia. Melalui perangkat yang terhubung, teknologi IoT memungkinkan pemantauan kondisi lingkungan secara real-time. Karena mereka dapat dengan mudah memantau parameter kualitas air dari jarak jauh. Selain mengurangi ketergantungan pada sumber daya listrik tradisional, penggunaan energi terbarukan menawarkan alternatif yang lebih ramah lingkungan dan berkelanjutan. Metode penelitian yang digunakan yaitu studi literatur, desain sistem, sensor, analisis data dan pengujian. Kesimpulan yang dapat diambil dari hasil penelitian yang telah dilakukan adalah Mikrokontroler Arduino Ide dengan sensor suhu DS18B20, sensor TDS SEN0244, dan sensor pH PH4502C telah berhasil digunakan untuk membangun alat pemantauan dan pengendalian kualitas air otomatis pada sistem budidaya ikan koi di akuarium berbasis Internet of Things dengan panel surya. Tingkat akurasi pengukuran suhu air, TDS, dan pH pada instrumen tersebut masing-masing mendekati 97%, 98%, dan 97%.

This community empowerment program aimed to enhance the productivity and sustainability of the Segara Ayu Kedonganan Fishermen Group by integrating digital accounting systems, digital marketing strategies, and fisheries science applications. The program addressed key challenges in financial management, marketing, and sustainable fisheries practices. The program adopted a participatory and educational approach to ensure that members of the Segara Ayu Kedonganan Fishermen Group were not merely passive recipients of assistance but were actively engaged in every stage of the process. Through a five-stage participatory approach—preparation, socialization, integrated training, field implementation, and evaluation—fishermen adopted digital financial recording, expanded online marketing channels, and improved post-harvest processing techniques. The outcomes included increased financial literacy, market access, product diversification, and environmental sustainability practices. The program also fostered collaboration between academia and local communities, contributing to the Sustainable Development Goals (SDGs) related to economic growth, responsible consumption, and life below water. The implementation of the program has proven to be highly effective in enhancing the business capacity and operational efficiency of the Segara Ayu Kedonganan Fishermen Group.

Mangrove forest ecosystems are vegetative communities found in tropical and subtropical estuaries and shallow coastal lagoons. They are mostly composed of several types of mangrove trees that can thrive in muddy beach tidal zones. The science and art of remote sensing involves analyzing data collected using instruments without coming into direct touch with the thing, location, or phenomena being researched in order to learn more about it. Sentinel-2A is a medium spatial resolution satellite image with a wide swath that can be used for studies on land cover monitoring, including vegetation, soil, and water, as well as water networks and coastal areas. It revisits the same location every 5 days, as opposed to Landsat's 16-day interval. The research findings indicate that there was an increase in the development of mangrove density between 2019 and 2023. Specifically, the total area of mangrove forests rose from 118.59 Ha in 2019 to 145.44 Ha in 2023. These developments are displayed in the table below

Rumput laut sebagai salah satu komoditas ekonomis penting dan merupakan salah satu sumber pangan dunia merupakan salah satu produk primadona di sector budidaya perikanan. Budidaya rumput laut relative mudah dibudidayakan, tidak memerlukan modal yang besar, tidak ada petisida, tidak ada residu dan tanpa pemberian pakan. Berdasarkan segi kualitas air yang berada di wilayah Bali yang mendukung pertumbuhan rumput laut dan juga sinar cahaya matahari yang cukup sehingga potensi dalam budidaya rumput laut sangat besar dan juga menguntungkan. Penelitian ini bertujuan untuk mengetahui seberapa besar potensi luasan wilayah yang dapat digunakan untuk budidaya rumput laut. Metode dalam penelitian ini yang digunakan ialah literatur review. Hasil analisis kesesuaian lahan di bali mendapatkan lahan potensial untuk budidaya rumput laut adalah perairan Pulau Nusa Lembongan sebesar 3.375,65 Ha. Luas lahan efektif sebesar 2.025,39 Ha yaitu 60% dari luas, serta total produksi pada satu musim panen sebesar 89.117,16 ton/siklus panen. Hasil pengukuran kualitas perairan menunjukkan parameter optimal yang meliputi suhu perairan 26 s.d 31 oC, salinitas 28 s.d 35 ppt, dan kedalaman 30 cm s.d 1 meter.
