Peningkatan sektor pertahanan nasional merupakan suatu hal yang penting dalam mempertahankan kedaulatan suatu negara. Salah satu diantaranya adalah dengan membuat Alat Utama Sistem Pertahanan Negara (ALUTSISTA) berupa kapal perang yang memiliki kecepatan tinggi, maneuver dan kekuatan struktur yang bagus. Ketika terjadi interaksi antara struktur kapal dengan beban gelombang maka akan muncul suatu tegangan. Jika tegangan yang dihasilkan melebihi batas tegangan yang diijinkan maka akan membahayakan dan merusak struktur kapal. Penelitian ini bertujuan untuk mengkaji desain lambung dan kekuatan struktur kapal untuk daerah operasional di perairan terbuka Indonesia yang memiliki tinggi rata-rata gelombang 3-5 m dan menurut standar Germanischer Lloyd (GL) dengan tinggi rata-rata gelombang 6 m. Pembahasan dititikberatkan pada analisis gerakan kapal untuk mengetahui kekuatan struktur kapal akibat adanya beban gelombang. Analisis dilakukan dengan melakukan pemodelan numerik dengan metode panel. Skenario divariasikan berdasarkan sudut hadap 900, 1350, 1800 dan tinggi gelombang signifikan 3, 4, 5 dan 6 m. Dari hasil simulasi didapatkan besar gaya lintang maksimal pada gerakan heaving dan momen lengkung maksimal pada gerakan pitching yang terjadi pada midship section ketika tinggi gelombang 6 m dan sudut hadap 1800. Tegangan terbesar kapal terjadi ketika kondisi sagging dan hogging maksimal yang terletak pada midship section frame 88 sebesar 231,89 N/mm2 dan memenuhi persyaratan tegangan izin berdasarkan GL rules.

Sandwich material can be used as the substitute for the ship conventional material. The core sandwich material used in this study consisted of a talk-resin-catalyst. The core mixture proportion is 90% resin and 10% talk. A thick steel plates is used as the face of the core sandwich material. Both experimental and numerical simulations are carried out to investigate the bending or flexural behavior of the proposed sandwich material. Three-point bending test has been carried out to determine the yield stress and maximum stress as well as the damage mechanism of the specimen up-to failure. From the investigation, the first failure process occurred at the mid-span as flexural cracks. As the load continue, these flexural cracks progressed until fully fracture of the core material take places. From the experimental investigation, it was found that the yield stress and maximum stress of the sandwich panel are 22.88 MPa and 28.63 MPa. On the other hand, numerical simulation is carried out using ABAQUS which has shown to be sufficient to predict the response of the sandwich-panel. However, a more sophisticated constitutive model is required to successfully model the experimental behavior in close agreement.

Plastic waste is generally discarded in waters from the river that will eventually empty into the sea and directly discharged into the high seas as happened in the village of Pesisir Besuki, Situbondo district. The problems faced by partners are the lack of public awareness of the short-term and long-term impact of waste disposal activities in the waters and poor management of waste management. So that required waste socialization that include the guidance in environmentally friendly waste management and able to increase awareness of coastal communities to care for the environment. This community dedication use socialization as method with questionnaire before and after activity. The results obtained after the activities carried out are increasing the insight of the people of the Pesisir Village, Besuki District and increasing awareness of the environment so that they are trying to manage the waste they produce independently. According to the questionnaires result, before socialization waste management in Besuki Coastal Region has percentage 73% citizen throw their wastes in the sea or/and the river, 27% has been burned, and 0% in temporary garbage disposal. After socialization, it became 13% throw their waste in the sea or/and the rever, 7% in temporary garbage disposal, and 80% choose to burn their wastes. Generally, they does not have the basic knowledge about marine debris impact with percentage up to 80% and the citizen who know about the knowledge is 20%. Their interest about self waste management is 33%. But after socialization, it became 67% for their interest. Keywords : Waste socialization, Waste Management, Environmental Care

The shipping industry is one of the future industries that has a major role in development because it can grow other maritime sectors to create new economic growth. Based on this, a study of hull repair is needed to support related industries. Hull repair cannot be separated from the sandblasting and painting processes. Sandblasting and painting are modern methods that aim to protect the hull from damage that can affect the life of the ship. The advantage obtained when the sandblasting and painting process meets the standards is that the repair results are more optimal to minimize shipyard expanses. In this study, the sandblasting process has followed the standards both at each stage and the calculation of estimated material requirements on the flat bottom, vertical side underwater, and topside position. In the painting study, the flat bottom and vertical side underwater position met the minimum requirements for paint, while the top side had a shortfall compared to the calculation of the estimated requirement of 8.8 liters.

Science is a system obtained through the scientific method of research. The application of scientific knowledge can be found in various fields such as agriculture, medicine, pharmacy, and technology. The development of scientific knowledge in various fields is the role of the academic community. Community service is one of the three main duties of higher education institutions. Community service activities are carried out by conducting visits to Jember Lor 01 Public Elementary School in order to enhance young generations' knowledge of science through primary schools. The method used in community service is practice experience, which is a learning process that provides practical experiences to facilitate students' understanding of the subject matter. The practices conducted include telekinetic and lava lamp experiments using easily accessible materials. The practices are done in groups and accompanied by one person from the community service team. Based on the enthusiasm of the participants, this activity has been very beneficial in increasing the interest in learning about science from an early age. The synchronization of this community service activity with the natural science subjects is necessary to help students understand the theoretical lessons taught by teachers.

Grenden merupakan salah satu desa di Kecamatan Puger dengan wilayah terluas dengan jumlah penduduk yang cukup banyak dengan sebagian besar wanitanya adalah ibu rumah tangga. Kebiasaan masyarakat yang masih belum bisa mengelola sampah secara mandiri menyebabkan adanya tumpukan sampah di beberapa tempat termasuk daerah aliran sungai dengan sampah yang dihasilkan umumnya merupakan sampah rumah tangga. Pengabdian dilakukan dengan objek mitra adalah para ibu rumah tangga. Sosialisasi diperlukan untuk mengedukasi mitra terkait bahaya dari sampah serta kiat-kiat mengolah sampah secara mandiri. Pelatihan pembuatan eco enzyme yang merupakan hasil fermentasi dari sampah rumah tangga menjadi salah satu solusi yang ditawarkan sehingga mitra mampu benar-benar menghasilkan produk kaya manfaat dari sampah yang mereka olah. Pemanfaatan eco enzyme dalam bentuk produk F2 sebagai pembersih karat dapat sangat bermanfaat terutama untuk karat pada beberapa bagian kapal yang banyak ditemukan di Puger maupun pada alat-alat rumah tangga. Metode pelaksanaan dari pengabdian ini adalah tahap pra kegiatan yang merupakan persiapan, pemberian pretest, tahap sosialisasi, pembelian bahan yang dibutuhkan untuk pelatihan, kemudian tahap pelatihan , pemberian posttest, hingga pengaplikasian produk pada benda yang berkarat. Hasil akhir F2 eco enzyme dipanen dalam waktu 90 hari setelah awal pembuatan dengan dikemas dalam botol berstiker yang siap jual untuk dipasarkan pada e-commerce. Setelah kegiatan sosialisasi dan pelatihan terdapat peningkatan pengetahuan peserta sebesar 74% dari rata-rata selisih nilai posttest dan pretest.
