Abstract

Melon is a high-value economic commodity with broad market demand. However, melon production in Indonesia has shown relatively slow growth. To address this issue, sonic bloom technology, which stimulates stomatal opening, can be combined with foliar fertilizer to enhance melon growth. This study aimed to determine the optimal sonic bloom frequency and foliar fertilizer concentration to improve melon plant physiological activity and growth. The research was conducted from January to April 2024 at the Faculty of Agriculture Universitas Sebelas Maret screen house. The experimental design followed a fully nested layout with two treatment factors: sonic bloom frequency (Hz) (F1 = 4,000 and F2 = 4,500) and compound foliar fertilizer application (control, 1, 3, and 5 g L-1). The fertilizer concentration factor was nested within the frequency factor and replicated four times in a randomized arrangement. Data were analyzed using 5% ANOVA, 5% Least Significant Difference (LSD) for mean comparison, and regression and correlation analyses. The results demonstrated that a 4,500 Hz frequency significantly increased chlorophyll b content, plant height at 5 WAP (weeks after planting), and number of segments at 5 WAP. . However, sonic bloom frequency had no significant effect on stomatal density, stomatal conductance, photosynthetic rate, chlorophyll a, total chlorophyll, or leaf number at 5 WAP. The regression analysis results indicated that the optimal foliar fertilizer concentration for enhancing melon growth ranged between 2.96 - 3.68 g L-1.Keywords: chlorophyll, nutrient, photosynthesis, soundwave, stomata

Abstract

The implementation of the Student Teams Achievement Division (STAD) learning model in the IPAS subject for Grade V students at SD Negeri 020 Tanah Grogot still faces several challenges. Therefore, the aim of this study is to investigate the cognitive learning outcomes in the IPAS subject for Grade V students at SD Negeri 020 Muara Koman. This study employs a qualitative research method with respondents consisting of teachers, students, and the school principal. Respondents were selected through purposive sampling based on the objectives of the research. Snowball sampling was also used through the involvement of participants recommended by initial respondents. The research procedure began with the researcher preparing instruments and instructional tools based on the Student Teams Achievement Division (STAD) learning model. The study was conducted using interview and observation techniques. Data analysis was carried out through both interim and final conclusions formed during the interview process. The results of the study indicate that the teacher respondent had prepared, implemented, and evaluated the implementation of the Student Teams Achievement Division (STAD) learning model in Grade V at SDN 020 Tanah Grogot. The student respondents had engaged in preparation, participated in the learning process, and demonstrated improved cognitive learning outcomes. Meanwhile, the school principal respondent had facilitated the preparation, implementation, and evaluation of the STAD learning model, resulting in enhanced cognitive learning outcomes among the students.

Abstract

Abstrak —Profesional Pemberi Asuhan meyakini atau mempersepsikan banyak kendala dalam penggunaan Rekam medis elektronik, termasuk tidak mudahnya penggunaannya. Hubungan antara variabel kemanfaatan dan kemudahan penggunaan terhadap sikap pengguna saat mulai implementasi rekam medis elektronik rawat jalan di RS Jiwa Grhasia Yogyakarta merupakan tujuan dalam penelitian ini. Metode yang digunakan adalah kuantitatif. Data dikumpulkan dengan membagikan kuisioner dan dilakukan uji statistik regresi linier berganda. Penelitian ini membuktikan adanya hubungan yang positif dan signifikan antara variabel kemanfataan dan sikap pengguna dan angka signifikansi yang dihasilkan yaitu 0.001<0.05. Hubungan yang diperoleh adalah positif dan signifikan antara persepsi kemudahan penggunaan dan sikap pengguna dengan nilai 0.003<0.05. Sedangkan kontribusi persepsi kemanfaatan dan kemudahan penggunaan rekam medis elektronik terhadap sikap pengguna adalah sebesar 61,9%, dan 39,1% sisanya dijelaskan oleh variabel yang tidak terdapat pada penelitian ini. Studi ini merekomendasikan bahwa ketika mengembangkan RME, perlu mempertimbangkan aspek kegunaan dan kemudahaan sehingga PPA terdorong untuk menggunakan RME untuk mendokumentasikan pelayanannya. Seperti harapan dari PPA yaitu RME dapat dengan cepat menyajikan data yang diperlukan.

Abstract

Competition among traditional food businesses is becoming increasingly intense, but studies that specifically discuss product development strategies in improving the competitiveness of locally based dodol businesses remain limited. This study aimed to analyze product development strategies in improving the competitiveness of the Tiga Putri Dodol Business in Singengu Village, Kotanopan Subdistrict. This study used a qualitative approach with a case study design, involving the business owner as the main informant and consumers as supporting informants selected through purposive sampling. Data were collected through interviews, observation, and documentation, and were then analyzed descriptively using the Ansoff Matrix. The results showed that competition among dodol businesses was relatively high, with eight business actors, while the Tiga Putri Dodol Business had a market share of below 10% despite experiencing an increase in revenue. The products produced were still limited to one flavor variant with relatively uniform traditional packaging, resulting in low product differentiation. In addition, the conventional marketing system caused limited market reach. Based on the Ansoff Matrix analysis, the relevant strategy is product development through increasing product variety and quality. These findings contribute to the development of marketing strategy and MSME competitiveness studies, while also broadening understanding of the importance of product innovation in the context of traditional food businesses. The conclusion of this study confirms that product innovation and strengthening marketing strategies are necessary to improve the competitiveness of the Tiga Putri Dodol Business, with support from business actors and the government in the development of locally based MSMEs.
