Abstract

Fresh water is an important requirement in fixed or moving structures such as ships. One way to provide fresh water is through a hydrophore system. Hydrophore was chosen as an alternative to public water tower systems because water towers were considered less aesthetically pleasing. Another consideration is that every part of the ship should be taken care of so that it does not interfere with the performance of the ship. The ship chose the hydrophore system because this system is dimensionally more practical when compared to a water tower. The installation of a water basin on a ship must take into account the number of turns and valves in the outlet pipe. A hydrophore simulation tool with many bends and valves is required to predict the adequacy of water demand on board. This research was conducted to determine the conditions and obtain the specifications from the hydrophore system. The support created consists of 3 turns and 1 valve. The bus emission specification is 9x10-3 m3 with an inlet pipe flow rate of 391x10-6 m3/s and an outlet pipe flow rate of 343282x10-3 m3/s. Major head loss is 21x10-3 m and minor head is 0.7 m.

Abstract

Many steel industries use scrap material as their basic material, both in the machine industry and the metal industry. The reason for using scrap is because this material is easy to obtain, has a high comparative value, has a chemical composition that is still very possible for further processing, and can reduce problems related to metal waste. Scrap material has a non-uniform type and chemical composition. The mistake in determining the type and composition of the basic ingredients will risk producing products whose specifications are not as expected. For that, before scrap is processed, it must first be grouped according to its type, then it is necessary to know in advance the chemical composition of each type of scrap ferrous material. Calculation of material composition before smelting must be precise, referring to the chemical composition standard that becomes the reference. The production of scrap iron into concrete reinforcing steel at PT Abadi Jaya Manunggal shows that scrap iron can be recycled and processed to produce reinforcing steel for concrete by taking into account the correct scrap composition. The chemical composition test results of scrap iron smelting show a composition identical to that of grade 250 steel. The result of the calculation of carbon equivalent is 0.317%, lower than the required maximum limit of 0.6%.

Abstract

Background. Panyaweuan tourist attraction. This tourist object is situated in Argapura, within Argamukti Village, Argapura District, Majalengka Regency, West Java, and is an excellent attraction for development. However, the Panyaweuan tourist object still offers minimal tourist attractions (attractions), accessibility (accessibility), facilities (facilities) of tourism institutions (ancillary), and community involvement (community involvement). Hence, it needs to identify potential tourist attractions. Purpose. Formulating a development strategy for Panyaweuan tourist attractions in Argamukti village, Argapura District, Majalengka regency, Method. This research was conducted at the Panyaweuan tourist attraction in Argamukti village, Argapura district, Majalengka Regency. It is a field research study involving observations, interviews, and documentation for data collection. Result. The results of data collection from observations, interviews, and documentation are described in accordance with the current conditions and circumstances. The results of describing potential objects and tourist attractions at the Panyaweuan tourist site in Argamukti village, Argapura district, Majalengka Regency, will be analyzed using SWOT analysis. Then, the priority strategy analysis will be carried out based on Internal Strategy Factors (IFE = Internal Factors Evaluation) and External Strategic Factors (EFE = External Factors Evaluation) in the development of tourism as a tourist destination. Conclusion. The tourism development strategy in the Panyaweuan tourist attraction of Tejamulya village is an agro-tourism-based tourism by looking at the potential in the form of natural beauty, the potential of agricultural and plantation products, supported by products produced by the community in the Panyaweuan area, so that it can provide economic benefits to the local community. However, Panyaweuan must enhance its supporting facilities to ensure visitor comfort and satisfaction. Additionally, all activities parwisata must be community-based with technological readiness (TKT) 3 and will be published in the Udayana-Bali tourism journal.

Abstract

Pelatihan di hotel merupakan sebuah upaya menunjang kualitas dari sumber daya manusia. Pelatihan memerlukan analisa yang tepat agar memiliki dampak yang baik bagi sebuah hotel. Penelitian akan analisa kebutuhan pelatihan harus dilakukan agar jenis pelatihan yang diberikan dapat tepat guna. Melalui penelitian kuantitatif, peneliti memaparkan sebuah 11 indikator capaian kepada 20 responden di departemen tata hidang dengan dibantu penarikan kuesioner. Setelah itu, penulis memaparkan hasil dalam bentuk hitungan skala Likert dan dibantu dengan metode garis kontinum sebagai pemaparnya. Hasil menyeluruh didapati hanya terdapat 4 indikator yang dinilai masih “ragu” dikarenakan berbagai faktor internal hotel. 7 indikator lainnya berhasil mendapatkan nilai positif berupa “setuju”. Nilai positif ini merupakan hasil kerja keras dan kerja sama yang terjalin baik antara manager tata hidang dengan manager sumber daya manusia. Hal tersebut tidak menutup kemungkinan bagi Hotel Prima Cirebon untuk dapat terus mengembangkan hotelnya kearah yang lebih baik di kemudian hari. Kata Kunci: analisa kebutuhan pelatihan, hotel, tata hidang
