Abstract

AbstrakPrediksi nilai kepadatan tanah dasar dalam pekerjaan jalan biasanya dilakukan dengan pendekatan non-spasial sampling. Metode prediksi spasial dengan pendekatan geostatistika yang diterapkan bertujuan untuk memprediksi dan memetakan nilai kepadatan. Metode yang digunakan adalah metode kriging berdasarkan model semivariogram. Hasil prediksi diuji melalui validasi dengan menggunakan data nilai kepadatan kering hasil pengukuran sandcone. Hasil analisis menunjukkan bahwa nilai kepadatan memiliki korelasi spasial dengan keragaman yang dipengaruhi jarak dan tipe sebaran, serta arah sebaran data kepadatan tanah dasar. Model semivariogram dipengaruhi oleh nilai range dan sill. Nilai range pada data lapangan zona 1 (mean γD =1,1845 gr/ cm 3 ) sebesar 135,667 meter sedangkan zona 2 (mean γD =1,332 gr/cm3 ) sebesar 319,80 meter. Sehingga dapat dikatakan bahwa besarnya nilai γD akan mempengaruhi jarak pengambilan sampel. Keseragaman hasil pemadatan pada bagian jalan dapat dievaluasi dengan menggunakan pendekatan geostatistik. Nilai mean dari data kepadatan dan nilai standar deviasi menentukan tingkat keseragaman hasil pemadatan tanah dasar. Standar deviasi 0,003 memberikan nilai RMS error sebesar 0,0025 sedangkan jika standar deviasi 0,005 nilai RMS error menjadi 0,005. AbstractPrediction of the value of subgrade density in road works is usually done with a non-spatial sampling approach. The spatial prediction method with the applied geostatistical approach aims to predict and map density values. The method used is the kriging method based on the semivariogram model. Prediction results were tested through validation by using dry density value data from the measurement results of sandcone. The results of the analysis show that the density value has a spatial correlation with diversity influenced by distance and type of distribution, as well as the direction of distribution of subgrade density data. The semivariogram model is influenced by range and sill values. The range value in zone 1 field data (mean γD =1,1845 gr/cm3 ) is 135,667 meters while zona 2 (mean γD =1,332 gr/cm3 ) is 319,80 meters. So that it can be said that the magnitude of the value of γD will affect the sampling distance. Uniformity of the results of compaction on parts of the road can be evaluated using a geostatistical approach. The mean value of the density data and the standard deviation value determine the level of uniformity of subgrade compaction results. The standard deviation of 0,003 gives the value of the RMS error of 0,0025 while if the standard deviation of 0,005 the value of the RMS error becomes 0,005.

Abstract

This research aims to investigate the contribution of teacher internship programs and self-improvement efforts to the formation of superior educators and increasing professionalism within the Center of Excellence (CoE) Vocational School environment. The research method used is a qualitative method with a case study approach. The data collection techniques used were participatory observation, interviews with teachers who had participated in the teacher internship program, and analysis of documents related to program implementation. The research results show that teacher internship programs and self-improvement efforts significantly increase teaching competence, understanding of the latest curriculum, and teacher managerial skills in transferring knowledge in the classroom through more structured learning practices, teachers who are straightforward in delivering material, and sharing experiences with another teacher related to internships. Recommendations from this research involve increasing collaboration between educational institutions and industry, providing stronger support from the government and schools for teacher self-improvement efforts, as well as developing teacher internship programs that are more structured and results-oriented to form students who are ready to enter the world of work. in line with industry expectations. To achieve this, teachers are needed whose competencies are expected to be in line with industry needs.

Abstract

The bon (store-credit) system is a transaction practice that continues to be used in community retail businesses. However, studies specifically analyzing the relationship between the bon system and the implementation of the marketing mix in traditional retail businesses remain limited. This study aimed to analyze the implementation of the marketing mix within the bon system at Kedai Harian Adifa, Koto Tangah Nagari, and to identify constraints in its management. This study employed a qualitative approach with a descriptive design through field research. The informants comprised the owner of Kedai Harian Adifa and five consumers selected based on their direct involvement in the bon system. Data were collected through interviews, observation, and documentation and subsequently analyzed through data reduction, data presentation, and conclusion drawing. The results showed that, of the five marketing mix elements analyzed—product, price, place, promotion, and people—price and promotion were the elements most closely associated with the implementation of the bon system. The system provided customers with payment flexibility while strengthening trust-based relationships between the store owner and consumers. However, its implementation faced constraints in the form of late payments and the risk of uncollectible receivables, which could affect business sustainability. These findings extend understanding of the contextual implementation of the marketing mix in microenterprises, particularly in managing credit-based transactions in traditional retail businesses. This study emphasizes the importance of more structured recording, monitoring, and control of the bon system to ensure that transaction flexibility can continue to be offered to customers without disrupting cash flow and business sustainability.
