The purpose of this study was to determine the structure and condition of seagrass communities  in the waters of hadirin Beach and Batu lawang karimunjawa. national park. This exploratory research used descriptive qualitative methods, each study location is divided into two transects. Data identified at SPTN Office 1 Kemujan Karimunjawa National Park. The results of the study were six species of seagrass, namely: Holodule uninervise, Thalassodendron ciliatum, Halophila minor, Syringodium isoetifolium, Thalassia hemprichii and Cymodocea serrulata. The percentage of seagrass cover namely Holodule uninervise is 38.04 %. Thalassodendron ciliatum of 6.25%, Halophila minor of 29.56%, Syringodium isoetifolium of 31.25%, Thalassia hemprichii at 14.21% and Cymodocea serrulata to 16.9%. The highest density of seagrass species in Hadirin Beach is from the Uninervise holodule species 72.30%, with 858 stands on the first transect and 54.66% on the second transect with 253 stands. Whereas for the highest Batu Lawang Beach is the species of Thalassia hemprichii 51.1% with 162 stands, on the first transect and 44.9% with 114 stands. The substrate has the type of sandy clay and coral fragments. Holodule uninervise is the most dominant species found on the beach of Hadirin meanwhile Thalassia hemprichi is the most dominant species in Batu Lawang.

Bencana Banjir menjadi salah satu fokus perhatian, karena masih banyak menimbulkan kerugian dan korban jiwa. Banjir dapat terjadi akibat meluapnya air, karena itu diperlukan deteksi dini terhadap level air. Menurut dibi.bnpb.go.id terdapat total 3257 bencana banjir di Indonesia pada tahun 2020-2022. Tujuan pembuatan alat Sistem Monitoring Cuaca dan Peringatan Banjir Berbasis IoT Menggunakan Aplikasi Mit App Inventor Untuk membantu masyarakat di berbagai wilayah yang rawan banjir agar dapat memonitoring dan sadar atas ancaman banjir. Mikrokontroler menggunakan Wemos D1 R1 yang sudah ada modul esp 8266 sehingga bisa tersambung ke jaringan internet. Internet of things merupakan teknologi untuk mengirimkan data sensor secara realtime. Penelitian menggunakan 3 jenin sensor berupa sensor ultrasonic yang mampu mendeteksi ketinggian air, sensor hujan mampu menginformasikan cuaca berupa intensitas hujan dari mulai hujan gerimis, hujan sedang dan hujan deras dan sensor dht 11 yang mampu mendeteksi data suhu disekitar. Data yang diperoleh dari ketiga sensor bisa langsung dipantau secara realtime di smartphone dengan menggunkan aplikasi Mit App Inventor. Setelah melakukan uji coba alat mampu memberikan data suhu disekitar alat dan peringatan dini bencana banjir yang di tandai dengan bunyi buzzer dan indikator Led.

The purpose of this study was to determine the activities of planning, implementing, observing, and evaluating in nurturing the spirit of edupreneurship in non-permanent teachers at Madrasah Ibtidaiyah in other Batu City through digital content creator training. The method used is PAR (Participatory Action Research). The PAR method involves researchers and communities working together to identify and resolve problems. Activities at this planning stage, namely the preparation of training activity materials. This activity was carried out in the form of a focus group discussion (FGD) involving the chairman of the Batu City KKMI, representatives of teachers, researchers, and resource persons. The agreed FGD results. The action stage is actualized with a training event that is divided into two mirrors. First, making learning videos. Both uploads. Observations, observations that have been made in the training obtained weaknesses and strengths experienced by researchers, coordinators, and teachers both in terms of attitudes and obstacles in training such as facilities and infrastructure. Reflection and evaluation activities are in the form of conveying supporting and inhibiting factors during the training activities and giving appreciation to participants
