This work provides variation in mechanical properties such as tensile, flexural and impact strength of hybridized kenaf and pineapple leaf fibre-reinforced high-density polyethylene composite. Two or more natural fibres are hybridized to provide an effective means of designing materials for various service requirements. The composite of kenaf/pineapple leaf fibre high-density polyethylene-based hybrid composite with different weight proportion of fibres were prepared. Total overall fibre loading in the composite was kept at 40%. The hybrid composites prepared were subjected to water immersion for 14 days to see how this concept can affect water uptake. At equal percentage ratio of the fibres, hybridization effect was optimized for tensile and flexural test; however, K6P4 gave the optimum impact strength while K3P7 resulted in the least overall water uptake. Strength and modulus values increased with increase in percentage of pineapple leaf fibre in the composite and the higher aspect ratio of kenaf helped in the dispersion of matrix in the composite. Favorable balance between the inherent advantages and disadvantages of these two fibres complemented each other. While pineapple leaf fibre helped the composite in tensile and flexural properties, kenaf provided impact strength and in reduction of water uptake. Dependence of modulus on the percentage of cellulose in natural fibres was clear. Kenaf and pineapple leaf fibre offered tremendous potential for hybridization. SEM was used to describe this interesting phenomenon.

This research is aimed to produce a design of learning model in the form of a practical technopreneurship scientific learning model for learning in higher education of vocational education and training. Type of the research is research and development. It was limited to, identify that technopreneurship scientific learning model is practical, and then the product was tested with users; lecturers and students. The questionnaire for assessing the practicality consisted of level of practicality sheet for the users. This instrument was made by using linkert measuring scale. The practicality sheet covered lecturer and students perception towards technopreneurship scientific learning model. It can be practical if it meets the criteria of aspect which is tested to the lecturer to identify attractiveness aspect, aspects of the development process, aspect of user practicality, aspect of functionality and usability, and the aspect of reliability. The result of the research shows that technopreneurship scientific learning model is practical from the lecturer’s view. Besides, from the students’ view, by identifying the students’ interest, the process of its use, improving students` activeness in learning process, the product is also practical. These research findings prove that technopreneurship scientific learning model is practical and be able to be used in higher education, especially in practice courses which expect the students to produce a good product in the form of prototype, blueprint, and concept. This technopreneurship scientific learning model can be developed and used in different courses based on the learning needs.

This study used a sample of 30 employees of Raharja College, Cikokol, Tangerang which were taken randomly to test the effect of the quality of human resources, job evaluation, incentives on employee productivity. The survey method with path analysis technique was used to analyze the pattern of relationships between variables with the aim of knowing the direct or indirect effect of a set of independent variables (exogenous) on the dependent variable (endogenous) with data analysis using the smart PLS 3.0 version software. The results show that the quality of human resources has a positive effect on employee productivity with a path coefficient value of 0.145, the quality of human resources has a positive effect on incentives with a path coefficient value of 0.121, incentives have a positive effect on productivity with a path coefficient value of 0.784, while performance evaluation has no positive effect on employee productivity with a path coefficient value of -0.103. It can be said that all the hypotheses in this study only one that does not have a positive effect while the rest have a positive effect. From the results of the data analysis, it can be seen that the quality of human resources directly affects employee productivity at Raharja College. Thus, the hypothesis which states that the quality of HR has a direct effect on employee productivity is accepted.

Butis butis atau dalam bahasa inggris disebut crazy fish termasuk ke dalam Famili Gobiidae. Sering dijumpai sekitar perairan di kawasan hutan mangrove yang merupakan ikan penghuni tetap. Masyarakat pesisir Belawan lebih mengenalnya dengan sebutan ikan butuh keleng atau gabus malas, karena ikan ini sering dijumpai selalu menggantung di daun dan ranting mangrove yang ikut terbawa arus. Penelitian ini bertujuan mengetahui kelas ukuran dan pola pertumbuhan ikan butuh keleng di perairan Sungai Belawan. Penelitian yang dilakukan bersifat eksploratif. Pengambilan sampel menggunakan alat tangkap pancing, menggunakan umpan berupa udang yang dikupas. Penangkapan dilakukan pada saat air sedang surut antara jam 08.00 - 12.00. Analisis data menggunakan aplikasi Microsoft Excel 2010.  Berdasarkan hasil tangkapan ikan untuk kelas ukuran diperoleh ikan ukuran kecil sebanyak 26 ekor, ukuran sedang 5 ekor dan ukuran besar 2 ekor. Pola pertumbuhan ikan butuh keleng dari 33 ekor ikan yang tertangkap,  menunjukan nilai persamaan W=0,3514L0,3235 dan nilai R2 = 0,952. Dengan demikian hubungan panjang berat ikan butuh keleng di Sungai Belawan bersifat alometrik negatif.
