Base on the survey and field visiting at the industry location, the state of traditional dockyardindustry in Bagansiapiapi is reported. Traditional dockyards use wood as raw materials for buildingsmall boat of less than 5 GT for cargo or passenger as well as fishing boats. The location of dockyard isbuilt open on the bank of riverine in the coastal area without any covered building. Even facilities in thetraditional dockyard as well as the way to the location are almost no any infrastructure to support it. Thedockyard persists on the wetland environment, swampy area, and unhealthy working condition. Themanagement of the dockyard is family wise as it belong to the one core family, but the boat craftmenmostly extent family. While the technology used mostly is not deliberately heritage from their ancient orotherwise from the long experiences working in the dockyard for many years. The main problem of thetraditional dockyard is the raw wood materials are scare so that difficul to get with high costly price,whilst capital to secure matereials stock unavailable. The consequence, three of four traditional dockyartsurveyed have already or stopping to product a new boat and frustrating to pace the future. The probableeffective idea way out of the situation is to use alterentive boat substitute material such as FRP. Thisidea will be verified by following studies on modern dockyard producing small boat with using alterna-tive non-wood material. It is necessary as a reference for the transformation of the traditional dockyardinto the modern one.

Pengelasan merupakan teknologi yang banyak digunakan untuk penyambungan logam. Namun hasil pengelasan yang diterapkan pada paduan aluminium tidak selalu menghasilkan sambungan dengan kualitas yang baik, hal ini dapat disebabkan salah satu faktornya adalah dalam menentukan jenis logam pengisi. Penentuan jenis logam pengisi ini akan menentukan kekuatan hasil las dari paduan aluminium. Untuk melihat sejauh mana pengaruh jenis logam pengisi tersebut, maka pada penelitian ini penulis menentukan tiga jenis logam pengisi yaitu ER 4043, ER 2319, ER 5056 pada proses pengelasan GTAW untuk paduan Aluminium 6061-T4. Dari hasil pengujian tarik diperoleh nilai kekuatan tarik terbesar pada paduan Aluminium 6061-T4 yang menggunakan jenis logam pengisi ER 4043 yaitu sebesar 19,694 kgf/mm2. Hasil distribusi kekerasan untuk ketiga jenis logam pengisi nilai kekerasan paling rendah terletak pada daerah HAZ sehingga pada pengujian tarik spesimen patah rata-rata di daerah HAZ karena pada daerah tersebut terjadi overagedregion.

The essence and majaz are two words in the form of mutadhayyifan or relative term (relative terminology), in the sense of being two words which are always side by side and each word will enter into one of them. The scholars give different meanings to the words true and majaz. The difference is only in the formulation while the understanding is close together. What is meant by essence is a lafaz which is used according to its origin for a specific purpose. The purpose of lafaz was formulated by language transfer is to facilitate understanding in the use of the language. Whereas what is meant by majaz is First; Lafaz does not show the true meaning as desired by a language. Second; Lafaz is not according to its true meaning borrowed to be used in giving meaning to what is meant. Third; between the target of the meaning of lafaz used with the target borrowed from the meaning of lafaz there is a connection. In relation to law, the nature and essence are the same in terms of providing legal understanding. Legal conclusions can be drawn from a lafaz based on the intrinsic meaning created for that lafaz, whether lafaz is general or specific, an order or prohibition. Likewise, the legal conclusion can be drawn from a lafaz based on the meaning of majazi lent for lafaz.

This study aims to determine the minerals contained in fish bones using X-Ray Diffraction (XRD) and to find out the values that are relevant to standard values. This study used a test sample in the form of a beam with a length of 30 cm, a width of 10 cm and a height of 15 cm with the composition of fish bone powder varied from 10%, 15%, 20%, 25% and 30%. Make batako with a mix of sand, semen, air and fish bone powder. Based on the results of testing each parameter parameter, analysis of fish mineral minerals using XRD. The yield of fish oil (CaO) content is 65%, zinc (ZnO) 11%, Iron (Fe2O3) 22%, and Cu4O3 2%. While the average value for each parameter in the composition of 10% to 15% is obtained by the compressive strength of 25.21 Kg / cm2 and 40.16 Kg / cm2 (according to the SNI 3-0349-1989 standard class category IV and class III level of solid concrete brick).Keywords: brick, compressive strength, fish bone

Budgeting of production costs is very useful as a tool to find out and predict the costs of production process in order that any surplus or deficiency of the production components can be avoided. As a result, carrying out performance measurement for cost control becomes more simple and eventually the goal is achieved. The purpose of this study is to determine the role of the production cost budget as a means of controlling production costs. The data used in this research are gained from the interviews with relevant authorities and direct observation to record the budget and the realization of production costs in 2018 and 2019. Analysis of the difference in costs is conducted at PT Yudhistira Ghalia Indonesia using qualitative methods. The results of the research is obtained by comparing the budgeted costs with costs realization. The control of production costs can be done optimally. However, the company does not have factory’s overhead costs budget that distinguishes between fixed overhead costs with variables. It is also found out that there are deviations in direct labor costs resulting from the increased spending due to the hiring of new employees. Key words : Production Cost Budget and Cost Control
