Abstract

Corrosion is damage caused by chemical reactions between metal materials and other natural elements and is destructive to metal. Corrosion is a weakness in ships made of steel, namely because the rate of ship corrosion, fatigue life is reduced, tensile strength and other mechanical properties are reduced. Corrosion is concentrated on only certain parts. In metal corrosion current flow out onto other parts of the metal surface. Corrosion gastric plates result in reduction Hull panel strength, slowing the ship and reduces security guarantees. The hull must be protected from corrosive attacks routine to prevent loss of additional plates substantially due to seawater corrosion. For Prevent hull corrosion in the painting process for coating, cathodic protection process. In this article, a system for automatically detecting ship hull painting results using image processing is explained. This system will be developed into a portable system. The results obtained show that the system is able to recognize whether the painting results can be accepted or rejected. Accepted means no need to repaint. and if it is rejected, it means a repainting process is needed.

Abstract

Research in the last decade, particularly in this research there are methods and steps for completion, namely 4 process steps, including: First of all, take samples and image data from the parts of the ship that are being repaired and maintained, Then, in making the prototype tool resulting from the coating, it is assembled using several tools, mini PC is installed with a web camera, next the image for the observation further processes and processed using the edge method contours detection with the help of cany to obtain the contrast and contour from the ship's hull. For next process, uses Neural Network for image creation processes taken from prototype plating or plating on observed ship parts. Some mixed results from the process. The images taken areand thenthe data obtained is processed and its form is observedfor shape, pattern,corrosion, contour and so on layers formed. There are two classifications of RGB and GLCM results, the rejected results can match the corrosion spot found on the hull, and the accepted results mean no corrosion spot found.

Abstract

Work accident is an undesirable and unexpected event that can cause human and/or property casualties (Permenaker No. 03/MEN/1998). In Indonesia, the number of work accidents in the construction sector is still relatively high. Based on BPJS Employment data, in 2019 there were 77,295 cases of work accidents in the construction sector. Based on this, Occupational Safety and Health in carrying out construction work is given great attention. One of the most important and always required PPE is a safety helmet. Based on the many needs for PPE helmets, many brands of safety helmets are sold on the market without knowing their advantages and materials, many accidents have occurred, and many helmets have broken and other failures. Based on this, research was carried out on the analysis of compressive strength and durability of SNI and non-SNI safety helmet materials. The aim of this research is to determine whether the compressive strength and shock resistance of safety helmet materials comply with standards. The research used a qualitative method by testing safety helmets. The test results showed that the SNI safety helmet passed the pressure and shock resistance tests, while the non-SNI safety helmet did not pass the pressure test but still met the shock resistance test. This value will be used as a reference for innovating safety helmet materials.

Abstract

Kurangnya ketersediaan air bersih di Dusun Sungai Geneng, Desa Pelang, Kecamatan Kembangbahu, Kabupaten Lamongan dapat menyebabkan warga mudah terserang penyakit. Oleh karena itu, perlu diadakan acara sosialisasi kepada masyarakat untuk memperoleh wawasan tentang air bersih dan sosialisasi cara penggunaan alat filter agar dapat memakai dan mengkonsumsi air bersih dalam kehidupan sehari-hari. Beberapa acara yang dilakukan dalam kegiatan pengabdian ini, yaitu: Pertama, survei pengamatan dan analisis kondisi lapangan terhadap kondisi air sumur dan telaga yang ada di masyarakat lingkungan Dusun Sungai Geneng tersebut. Kedua, sosialisasi kepada masyarakat untuk memperoleh wawasan tentang air bersih dan sosialisasi cara penggunaan alat filter. Ketiga, pelatihan perawatan alat filter air dan tangki penampungan air bersih kepada masyarakat. Bedasarkan hasil analisis, antusias warga dalam mengikuti acara pengabdian masyarakat ini dikarenakan beberapa hal. Diantaranya adalah banyak warga yang mudah terserang penyakit karena adanya penggunaan air yang kurang bersih, kurangnya pengetahuan tentang air bersih, dan belum mengetahui cara merawat alat filter air dengan baik sehingga alat tersebut tidak mampu bertahan lebih lama dan air yang mengalir ke dalam tangki menjadi cepat kotor.

Abstract

This research discusses the method of making distribution pipes using the Submerged Arc Welding (SAW) welding process, especially for pipes with spiral connections. The material used is API 5L X65. SAW pipes with spiral joints are more commonly used for low-pressure piping systems. However, in certain cases, the production of SAW pipes for Sour Service distribution requires special treatment. Sour Service pipes have a high level of corrosion and residual stress, so Post Weld Heat Treatment (PWHT) is required to prevent Hydrogen Induced Cracking (HIC). HIC occurs due to the absorption and accumulation of hydrogen gas in the metal, causing the formation and growth of cracks, which is also influenced by residual stress. PWHT is applied to reduce residual stress to reduce the risk of corrosion. PWHT is a process to change the structure of the weld metal by heating the metal at a certain temperature and time. This research shows that variations in PWHT temperature produce an average residual stress that is not much different with less difference than 2%, In corrosion testing with the HIC method shows crack evidence but is still satisfactory NACE MR0175 criteria for pipe PWHT temperature variation conditions

Abstract

Peluang terciptanya lobster air tawar sebagai komoditas perikanan semakin terbuka seiring dengan semakin populernya dikalangan pembudidaya dan konsumen, apalagi lobster air tawar ini pun mempunyai keunggulan bila dibandingkan dengan komuditas perikanan lainnya yang sudah berjalan. Usaha budidaya lobster masih ditemui beberapa kendala, diantaranya kematian akibat gagalnya proses molting, dan kematian akibat kanibalisme. Kanibalisme umumnya terjadi saat molting, hal ini terjadi karena pengerasan cangkang terlalu lambat. Sehingga pada kegiatan PkM ini diajukan kegiatan pengabdian kepada masyarakat untuk dapat membuatkan wadah atau bak kolam budidaya yang terdapat instalasi perpipaan yang mendukung serta menghemat lahan dan terdapat pencahayaan yang cukup. Pada kegiatan PkM ini dihasilkan Desain perpipaan yang digunakan pada desain perpipaan air bersih dengan peletakan pipa system pengaliran ke atas, system ini dipilih agar sirkulasi air bersih optimal pada kolam budidaya. Prototype bak pembudidaya dirancang dengan menggunakan 3 tingkat dari bahan kerangka besi hollow serta dinding terpal, hal ini dirasakan lebih sesuai dengan instalasi pada kolam budidaya yang membutuhkan lahan terbatas dan cocok digunakan untuk pembudidayaan lobster air tawar.
