Abstract

The ideal science learning reflects the domain of balanced scientific literacy. Student who has scientific literacy are able to master science content, understand the characteristics of science and be able to recognize the environment through scientific process and apply science concepts in real life. Based on that statement we developed a research-based teaching material. This study aims to analyze the effectiveness and appropriateness of teaching materials about Interaction of Living Things with the Environment for grade VII. The research method was used Research and Development teaching materials. Data taken in the form of module eligibility was validated by the media and material experts. Teaching materials effectiveness was analyzed by posttest score, teaching materials characteristics was described by the percentage of teaching materials characteristics based on scientific literacy. The results showed that the science teaching materials have developed was valid, feasible, and effective to support Interaction of Living Things Learning. It have characteristics based on scientific literacy and equipped with pictures to clarify the practicum process, completed with observation tables as testing data that could guide students to find the concepts being taught.

Abstract

This study aimed to develop learning media in the form of chemistry learning videos and used as a medium to facilitate the study of chemical bonding material. The method used is research and development (Research and Development) with the ADDIE model (Analyze, Design, Development, Implementation, Evaluation. The feasibility of this media is seen from the material, media and language feasibility assessment sheets which are validated by three experts in their respective fields The results of the feasibility test of material, media and language respectively obtained an average percentage of 94%, 92.7% and 96% which shows that this chemistry learning video media is very feasible to use.Keywords: Development; media; chemistry learning videos

Abstract

Record databases are generally still often displayed in text form as information for users, so it can facilitate cryptanalyst to access and provide opportunities to do the leak, distribute or modify the database records. One of the cryptographic algorithms used to secure data is using the DES algorithm to encrypt the data to be stored or sent. The DES algorithm belongs to a cryptographic system of symmetry and is a type of block cipher. DES operates on a 64-bit block size. DES describes 64 bits of plaintext to 64 bits of ciphertext using 56 bits of internal key (internal key) or up-key (subkey). The internal key is generated from an external key 64-bit length. This research describes the process of securing database records by encrypting it based on DES algorithm, resulting in text record databases in the form of passwords that are difficult to understand and understand by others. This is done in an attempt to minimize the misuse of database records.

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh secara parsial maupun simultan dari variabel Current Ratio (CR), Debt To Asset Ratio (DAR), dan Total Asset Turn Over (TATO) terhadap Return on Assets (ROA) pada PT Nippon Indosari Corpindo Tbk periode tahun 2014-2023. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan pendekatan kuantitatif. Sampel yang digunakan adalah laporan posisi keuangan dan laba rugi dari PT Nippon Indosari Corpindo Tbk selama 10 tahun dari 2014 sampai 2023. Data diolah dan dianalisa dengan menggunakan software IBM SPSS versi 26. Hasil penelitian ini diketahui thitung sebesar -0,023 < ttabel sebesar 2,447 dengan tingkat signifikan 0,982 > 0,05. Maka dapat disimpulkan bahwa Current Ratio (CR) secara parsial tidak berpengaruh dan tidak signifikan terhadap Return On Asset (ROA). Debt to Asset Ratio (DAR) secara parsial berpengaruh dan signifikan terhadap Return On Asset (ROA), hal ini dibuktikan dengan nilai thitung 2,505 > ttabel 2,447 dengan tingkat signifikan 0,046 < 0,05. Total Asset Turnover (TATO) secara parsial berpengaruh dan signifikan pada ROA dengan nilai thitung 5,174 > ttabel 2,447 dengan tingkat signifikan 0,002 < 0,05. Dan pada hasil pengujian terakhir diperoleh Fhitung 17,858 > Ftabel 4,35 dengan tingkat signifikansi 0,002 < 0,05 dapat disimpulkan ketiga variabel tersebut secara simultan berpengaruh signifikan terhadap ROA.
