Sekoci merupakan alat penolong yang dapat digunakan untuk evakuasi seluruh awak kapal karena memiliki konstruksi yang lebih kuat dari alat penolong lainnya. Masalah yang sering terjadi adalah kurang terampilnya ABK tentang perawatan dan pengoperasian sekoci yang sesuai dengan prosedur dan rendahnya  perawatan sekoci di atas MV Kartini Baruna. Kemudian tujuan penelitian ini yaitu untuk mengetahui penyebab kurang terampilnya ABK tentang perawatan dan pengoperasian sekoci yang sesuai dengan prosedur dan mengetahui penyebab rendahnya  perawatan sekoci di atas MV Kartini Baruna. Metode yang digunakan adalah deskriptif kualitatif. Dari hasil penelitian diperoleh kesimpulan bahwa faktor yang menyebabkan kurang optimalnya kinerja dari sekoci di MV. Kartini Baruna adalah kurangnya spare part, penerapan PMS (Plan Maintenance System) yang tidak sesuai ketentuan, kurang terampilnya anak buah kapal (ABK) dalam pengoperasian sekoci. Faktor yang menyebabkan perawatan lifeboat yang kurang baik terhadap crew di MV. Kartini Baruna adalah lambatnya proses pengoperasian sekoci, membahayakan keselamatan crew diatas kapal. Kemudian upaya yang dilakukan untuk mengoptimalkan perawatan terhadap lifeboat di MV.Kartini Baruna yaitu dengan menerapkan PMS (plan maintenance system) sesuai ketentuan atau panduan

In recent times, spare parts inventory systems have been extensively researched, but most inventory models were not fully adequate due to the stochastic nature of inventory environment. This paper proposes an approach that supports decision making process in planning and controlling of spare parts in aircraft maintenance systems. Reliability characteristics of aircraft consumable parts were analyzed in order to substantiate this approach. Moreover, the proposed reliability model was used to evaluate characteristics of subassemblies and/or assemblies these parts belong to. Finally, an innovative approach for determining the total amount of parts required in inventory and underage costs, based on observing the total unit time as a stochastic process, is presented herein.

Over time a machine will get experience a decrease in reliability, causing the engine to be damaged at the time of operation, thus disrupting the production line. To maintain a machine remains reliable then a good maintenance system is required. In this research, we will use Reliability Centered Maintenance (RCM) and Reliability Centered Spare (RCS) analysis on the critical system of Goss Universal printing machine based on engine failure data. The result of RCM analysis obtained the optimal preventive maintenance schedule and the type of treatment, while based on the RCS analysis obtained spare part needs following the maintenance schedule. With the result of this analysis, is expected where the machine will keep good and will continue to operate without a sudden breakdown under the production schedule's need. Based on RCM analysis for each critical subsystem obtained interval preventive maintenance for transfer roller 127.60 hours, Ink fountain roller 24.45 hours, ink form roller 29.23 hours respectively, and the wash-up device is no scheduled maintenance. For spare parts inventory strategies the result using RCS method are: transfer roller104 units, ink fountain roller requires 32 units, ink form roller 36 units and are holding spare policy required, and a wash-up device no holding spare parts.

Results of the Ayrshire breed cows, Holstein cows and Holstein-Yaroslavl cross breed cows milk productiv-ity analysis in the same environment conditions and depending on the kappa-casein and beta-lactoglobulin genotypes are presented in this article. The animals are kept in the common environmental conditions of the LLC Farming firm “Pakhma», the Ayrshire breeding plant. Feeding of cows here is carried out according to detailed norms, concentrated feed averages 43%. The maintenance system is year-round stalling, milking is carried out in the milk line, the DeLaval milking machine is used, and labor-intensive processes in animal husbandry are mechanized. The farm has a milk processing shop. It was established that all the inspected cows (n=91) had a prevailing AA kappa-casein genotype – 75,8% on average. BB Ayrshire breed and Hol-stein-Yaroslavl cross breed genotypes were not established. AB and BB beta-lactoglobulin genotypes are seen on average with a frequency of 44%. AA beta-lactoglobulin genotype in Holstein cows breed was not found. The indicators of statistically reliable difference in milkability among all groups and genotypes was not estab-lished. A higher consistence of protein in the milk of B-allele kappa-casein type cows is evident in all groups with no difference between breed belonging. The complex variant of CSN3/LGB genotypes showed that ac-cording to ultimate milk fat and protein yield the most productive cows were:АВ/ВВ, АВ/АВ genotype Ayr-shire cows, АВ/АВ Holstein genotype cows, AB/BB genotype Holstein-Yaroslavl cross breed cows. Hence, the most efficient cows are those with B-allele variants.

Standardisation of animal handling procedures for a wide range of preclinical imaging scanners will improve imaging performance and reproducibility of scientific data. Whilst there has been significant effort in defining how well scanners should operate and how in vivo experimentation should be practised, there is little detail on how to achieve optimal scanner performance with best practices in animal welfare. Here, we describe a system-agnostic, adaptable and extensible animal support cradle system for cardio-respiratory-synchronised, and other, multi-modal imaging of small animals. The animal support cradle can be adapted on a per application basis and features integrated tubing for anaesthetic and tracer delivery, an electrically driven rectal temperature maintenance system and respiratory and cardiac monitoring. Through a combination of careful material and device selection, we have described an approach that allows animals to be transferred whilst under general anaesthesia between any of the tomographic scanners we currently or have previously operated. The set-up is minimally invasive, cheap and easy to implement and for multi-modal, multi-vendor imaging of small animals.
