Abstract

Currently, in the sub-district of Sumbawa, West Nusa Tenggara province, there are many modern retail shops that have become competitors to the existence of traditional retailers that have existed before. Therefore, the aim of this research is to analyze the factors that influence the existence of traditional retailers with the existence of modern retailers in Sumbawa sub-district. This study uses a quantitative approach to statistical analysis using path analysis. The data used in this study is primary data, which is obtained through distributing questionnaires. It is known that the total population of the Sumbawa sub - district based on population data in 2019 is 61,518 people, so using the Slovin formula the number of samples for this study is at least 100 people (with an error rate of 10%). From the analysis using SEM and LISREL software obtained a mathematical model for the existence of traditional retails: existence = 0.59 decisions + 0.5 products - 0.078 price - 0.085 place + 0.49 with a value of R2 = 0.51 means the existence of traditional retail in the sub-district Sumbawa is influenced by decision, product, Price, and place varies by 51%, the remaining 49% is influenced by other variables. Meanwhile, from the results of the hypothesis analysis, it is found that the purchasing decisions of Sumbawa sub-district residents at traditional retail are influenced by price and place, while their existence is influenced by product variables and purchasing decisions. The factors that have a direct influence on the existence of traditional retail in the Sumbawa sub - district are product factors and buyer decision factors, while the factors that have an indirect effect are product factors through buyer's decision factors.

Abstract

Many universities at the national and local levels have resulted in the emergence of competition between universities in obtaining prospective students. Therefore, universities have to show all their potential and advantages in every aspect, including the Universitas Teknologi Sumbawa (UTS), even though it is ranked in the top five universities in West Nusa Tenggara. This study aims to analyze the factors of service quality, customer satisfaction, and experiential marketing that UTS has implemented has influenced the marketing of word-of-mouth techniques optimally or not in attracting prospective students to study at UTS. This study's results can provide an overview for UTS in providing services to students with administrative services carried out by staff and lecturers in teaching. This study's population was UTS students who were still actively studying with a research sample of 165 students. In order to achieve the objectives of this study, questionnaire data from respondents were tested by using the Structural Equation Model (SEM) method using LISREL 8.8 software. The research results obtained a structural equation: word of mouth = -21 × service quality + 0.3 × customer satisfaction + 0.71 × experiential marketing with R2 = 71%. The hypothesis testing results show that of the three variables, only experiential marketing variables have a positive and significant effect on UTS students' word of mouth decision.

Abstract

Melimpahnya produksi tani jagung di kabupaten Sumbawa berdampak pada melimpah juga limbah yang dihasilkan. Limbah jagung yang masih hijau dapat dimanfaatkan secara langsung untuk menjadi pakan ternak sapi, tetapi limbah yang sudah kering tidak dapat dimanfaatkan oleh peternak karena belum memiliki keterampilan. Oleh karena itu, dilakukan kegiatan pelatihan pembuatan pakan ternak dari limbah pertanian jagung kepada kelompok ternak desa Poto. Melimpahnya bahan baku dapat diproduksi pakan ternak dalam jumlah banyak, selain dapat dimanfaatkan untuk ternak sendiri juga dapat dipasarkan ke masyarakat luas. Berdasarkan hal tersebut maka dilakukan pengabdian lanjutan yaitu pelatihan desain kemasan produk pakan ternak dan pembuatan Etalase Poto Village sebagai media pemasaran produk-produk desa Poto, selain produk pakan ternak dari limbah jagung. Metode yang digunakan adalah metode monologis dan dialogis. Hasil evaluasi menunjukan peserta sangat puas dengan kegiatan pelatihan dan hasil analisis pretest dan posttest menunjukkan terdapat peningkatan pemahaman peserta setelah mengikuti pelatihan pembuatan desain kemasan produk pakan ternak dari limbah jagung dan peningkatan pemahaman menggunakan Etalase Poto Village.

Abstract

The best service includes providing fast service so that customers can arrive quickly. The service here can be in the form of improving the queuing system. Queues can occur if the need for a service exceeds the available demand. One service sector with a queuing system is the Community Health Center. The Community Health Center is a functional implementing unit that is a health development center for fostering community participation in the health sector. So, research was carried out to evaluate the queuing system at the Unter Iwes Health Center registration counter in Sumbawa District to optimize queuing services. The study results show that the queuing system currently used at the registration counter at the Unter Iwes Health Center, Sumbawa sub-district, namely Single Channel-Single Phase, is still optimal, as indicated by a steady state value of less than one. On Monday, it was found that the average queue in the system (????s) was one person, the average queue in the queue (????q) was one person, while the probability that the number of patients in the queue would not occur (????o) was 0%. The average waiting time in the system (????s) is 0.24 minutes, while the average waiting time in the queue (????q) is 0.15 minutes, the server busy level (K) is 64%, and the server unemployment level (W) is 36%.

Abstract

Preeclampsia is a serious pregnancy complication characterized by high blood pressure, potentially leading to organ damage, making early risk prediction crucial to reducing maternal morbidity and mortality. This study aims to develop a preeclampsia risk prediction model using medical and clinical data from 80 patients at Rumah Bersalin Sadan. The data include demographic profiles, blood pressure, weight, maternal age, preeclampsia history, body mass index, number of previous pregnancies, as well as genetic and environmental factors. The dependent variable is the risk of preeclampsia, either as a binary outcome (yes/no) or as a continuous risk score. The predictive model was built using multivariate linear regression and the Random Forest algorithm. The results showed that the Random Forest model achieved an accuracy of 65.22%, with an F-statistic of 7.345 and a very small p-value (1.908e-06), indicating that the model effectively explains data variability. However, the low Kappa value suggests room for improvement through feature refinement, hyperparameter tuning, or exploring other algorithms. Although these findings suggest that Random Forest is a promising method, further evaluation and model optimization are needed to enhance predictive performance and determine whether this method is the most suitable for the dataset used.

Abstract

This study intends to create a statistical learning model by integrating theory and practice, using the SPSS software application with case studies of problem solving in Computer Engineering and Informatics students at the Medan State Polytechnic. The design of this study began with a literature review before making lesson plans with the task of making teaching materials and providing content to students. Besides that, after the writer led the discussion, he was given the task of determining cases based on the subjects chosen by the students according to their interests. In this study there were 70 students who participated as the research sample. NONCase and STDCase both have standard deviation values ​​of 1.62001 and 1.84694, respectively. Because the average learning outcomes of NONCase 74.2571 and STDCase 78.8857 show that descriptively there are differences between NONCase-based learning and case study/STDCase-based learning. The NONCase method and the STDCase learning method using the SPSS program have a significant linear relationship between the variables, according to case study-based research. Using the formula F count = 0.982 > F table = 1.507 It can be concluded that there is a significant linear relationship between the mastery of the STDCase learning approach and the SPSS program because F count is smaller than F table

Abstract

Abstrak: Musim kemarau di Kabupaten Sumbawa ditandai oleh tingkat kekeringan yang sangat tinggi, yang berdampak pada terbatasnya ketersediaan pakan ternak. Kondisi ini berpotensi menurunkan produksi sapi, sehingga menghambat pencapaian program NTB Bumi Sejuta Sapi. Desa Poto, Kabupaten Sumbawa, merupakan salah satu daerah dengan produksi jagung yang melimpah berdampak pada meningkatnya jumlah limbah jagung. Produksi jagung yang melimpah menghasilkan limbah dalam jumlah besar, yang umumnya dibakar oleh petani untuk membersihkan lahan, meskipun hal ini menimbulkan polusi. Padahal, limbah jagung masih mengandung nutrisi yang bisa dimanfaatkan sebagai pakan ternak. Melalui program pemberdayaan kemitraan masyarakat, dilakukan pelatihan kepada Kelompok Tani Ternak Lenang Rea III untuk mengolah limbah jagung menjadi pakan alternatif menggunakan mesin pencacah (Hammer Mill). Pelatihan ini bertujuan meningkatkan hardskill mitra dalam fermentasi limbah jagung dan formulasi pakan ternak. Meningkatan softskill dalam kesadaran akan pentingnya inovasi, keberlanjutan lingkungan, dan potensi ekonomi dari limbah jagung. Tiga tahapan kegiatan meliputi diskusi, pelatihan pembuatan silase dengan metode Participatory Rural Appraisal (PRA), dan evaluasi. Hasil evaluasi menunjukkan tingkat kepuasan peserta cukup tinggi dengan skor total setiap variabel berada dalam rentang antara 0,72 hingga 0,88, yang mengindikasikan bahwa nilai pada masing-masing indikator berada pada kategori sedang (medium). Secara keseluruhan, nilai Technology Readiness Index (TRI) sebesar 3,14, menandakan kesiapan moderat dalam menerapkan teknologi pengolahan limbah jagung.Abstract: The dry season in Sumbawa Regency is characterized by very high levels of drought, which impacts the limited availability of animal feed. This condition can potentially reduce cattle production, thus hampering the achievement of the NTB Bumi Sejuta Sapi program. Poto Village, Sumbawa Regency, is one of the areas with abundant corn production, which impacts the increasing amount of corn waste. Abundant corn production produces large amounts of garbage, which farmers generally burn to clear the land, although this causes pollution. Corn waste still contains nutrients that can be used as animal feed. Through the community partnership empowerment program, training was conducted for the Lenang Rea III Livestock Farmers Group to process corn waste into alternative feed using a shredder (Hammer Mill). This training aims to improve the hard skills of partners in corn waste fermentation and animal feed formulation. Increasing soft skills in awareness of the importance of innovation, environmental sustainability, and the economic potential of corn waste. The three stages of activity include discussion, silage-making training using the Participatory Rural Appraisal (PRA) method, and evaluation. The evaluation process involved [specific details about the evaluation process]. The evaluation results showed that the level of participant satisfaction was relatively high, with the total score of each variable ranging from 0.72 to 0.88, indicating that the value of each indicator was in the medium category. Overall, the Technology Readiness Index (TRI) value was 3.14, indicating moderate readiness to implement corn waste processing technology.
