Abstract

Bisnis kecil dan menengah (UMKM) di Desa Labanasem tidak dapat bersaing dengan mitra lain untuk mendapatkan hasil terbaik karena teknologi tradisional. Untuk mengurangi biaya produksi dan biaya simpan produk, para mitra berusaha mengurangi biaya produksi, terutama dalam hal pengemasan. Akibatnya, mereka mengubah metode pengemasan mereka dari tradisional ke kontemporer. Produksi tidak efisien karena peralatan pengemasan terbatas. Karena hal ini, pemasaran produk menjadi lebih lambat. Tujuan dari program pengabdian ini adalah untuk menerapkan teknologi tepat guna, yaitu mesin vacuum sealer, yang dapat meningkatkan kualitas produk, kualitas kemasan, dan nilai ekonomi bagi UMKM di Desa Labanasem, Kecamatan Kabat, Banyuwangi. Berdasarkan masalah yang dihadapi UMKM, penerapan mesin vacuum sealer dapat membantu menyelesaikannya. Dengan adanya kegiatan pengabdian ini, produk mitra menjadi lebih tahan lama usia simpannya sehingga tidak banyak produk yang dibuang karena rusak atau usia simpan pendek.

Abstract

Comments in questionnaire feedback carry sentiment meanings, such as positive, negative, or neutral. Each review comment on training services requires prompt and accurate follow-up to improve service quality. However, sentiment classification often demands significant time and effort to determine sentiments accurately. This study aims to enhance efficiency and accuracy in sentiment classification for training questionnaires. A comparative analysis was conducted using three algorithms: Naïve Bayes, K-Nearest Neighbors (KNN), and Support Vector Machine (SVM). The results indicate that SVM is the fastest and most accurate algorithm, with a training time of 3.067 seconds, 100 milliseconds faster than Naïve Bayes and 45.8 seconds faster than KNN. SVM achieved an accuracy of 60.81%, with an average sensitivity of 61%, specificity of 80%, and precision of 63%. Subsequently, this study integrated the Optimized Weight Evolutionary method to enhance SVM's accuracy and address attribute selection. Testing results showed a 2.16% improvement in SVM accuracy, bringing it to 63.10%. The training process was conducted on a dataset of 1,153 comments, with 90% of the data used for algorithm training. The combination of SVM and Optimized Weight Evolutionary proved effective in achieving more accurate sentiment classification. This study provides new insights into the application of sentiment classification, particularly for training feedback. Optimizing the algorithm can help training companies respond more effectively to comments and improve overall service quality.

Abstract

Casting is the process of manufacturing molten metal with a mold to produce a shape close to the original shape. The commonly used molding sand is mountain sand, river sand and silica sand. This research aims to analyze defects and tensile test results of castings with various types of sand (beach sand and silica sand) and types of aluminum (ADC 12 aluminum and aluminum from waste cans). The casting method used is traditional sand blasting. The results show defects in the form of surface hardness, rat tails, shrinkage cavities, and pinholes. The tensile test showed that the highest Ultimate Tensile Strength (UTS) value was obtained from a mixture of Al ADC 12 with beach sand with an average UTS value of 172.44 MPa.

Abstract

The digital era has transformed parenting patterns, encouraging the need to integrate Islamic values in digital parenting practices. This study analyzes the concept of digital parenting through the lens of tarbiyah islamiyah and the impact of technology on child development psychology with a qualitative approach through library research. Content analysis was carried out on the literature of Islamic education and contemporary psychology to answer three research questions: (1) What is the representation of the concept of digital parenting and tarbiyah islamiyah in Islamic literature? (2) What is the impact of digital technology on children's cognitive, emotional, and spiritual development? (3) How can the principle of tarbiyah islamiyah be implemented in digital parenting? The findings reveal that digital parenting in Islam must be based on the concepts of muraqabah, tawazun, and ihsan, while technology risks causing developmental disruptions if not strictly supervised. This study offers an Islamic Digital Parenting framework that combines developmental psychology with Islamic values, emphasizing screen time restrictions, moral media literacy, and parental examples. Research recommendations include socialization of this model to parents and educational institutions, as well as the development of Islamic parenting curricula in the digital era.

Abstract

Disaster health education is included in disaster mitigation which aims to increase public knowledge and minimize casualties caused when a disaster occurs. School-aged children are a vulnerable group who are still unfamiliar with disaster knowledge, so there is a need for health education about disasters. The aim of the research is to determine the influence of health education on students' knowledge of drought disaster mitigation. This research uses a Pre-Experimental research type that uses a One-Group Pre-Test and Post-Test Design, and uses a total sampling technique with a sample size of 46 respondents. The results of the research before being given health education showed that 29 (63.0%) respondents were at a good level of knowledge with an average score of 10.17. The research results after being given health education increased students' knowledge level, namely 41 (89.1%) respondents had good knowledge with an average score of 11.93. The data analysis used was the Wilcoxon test, with a significance level of a=0.05, the result was r 0.000<a so that H0 was rejected and Ha was accepted. From these results it can be concluded that there is an influence of health education on students' knowledge of drought disaster mitigation.

Abstract

The purpose of this study was to determine the public service in Medan City Land Office. To find out the administrative system of land mapping in Medan City Land Office. To determine the effectiveness of legal benefits for the community on participatory mapping of Land Services at the Medan City Land Office. The research methods used are normative and empirical juridical research. The nature of the research used in this study is descriptive analysis. Sources of data used in this study are primary and secondary data. The data analysis method used in this study is descriptive qualitative. Based on the results of the study is the National Land Agency (BPN) is a vertical agency, as a vertical unit that organizes Land Services.

Abstract

Aplikasi konsentrasi PGPR dan aplikasi pupuk kotoran kambing merupakan salah satu langkah yang digunakan dalam intensifikasi. Hal tersebut karena PGPR mengandung beberapa mikroorganisme yang dapat berperan sebagai pemacu pertumbuhan dan mampu meningkatkan hasil produksi pertanian. Sementara itu, pupuk kotoran kambing dapat menambah unsur hara pada lahan sub-optimal yang cenderung kandungan bahan organiknya rendah, ketersediaan air rendah, keasaman tanah tinggi (pH rendah), dan sangat minim unsur hara. Penelitian dilaksanakan pada bulan Juni - September 2019 di lahan yang terletak di Donowari, karang ploso. Penelitian ini ialah penelitian faktorial dengan menggunakan rancangan acak kelompok, faktor pertama adalah R0: Tanpa PGPR, R1: PGPR 15 ml L-1, R2: PGPR 30 ml L-1. Faktor kedua adalah pupuk organik kotoran kambing, yaitu: P1: 0 ton ha-1, P2: 10 ton ha-1, P3: 20 ton ha-1, P4: 30 ton ha-1. Pengamatan yang dilakukan meliputi komponen pertumbuhan yaitu tinggi tanaman dan jumlah daun. Sedangkan parameter pengamatan komponen hasil meliputi jumlah buah pertanaman, bobot buah pertanaman, diameter buah dan bobot buah pertanaman. Data hasil pengamatan dianalisis dengan menggunakan uji F untuk mengetahui adanya pengaruh dari perlakuan dan dilanjutkan dengan uji antar perlakuan dengan menggunakan BNJ pada taraf kepercayaan 5%. Hasil penelitian menunjukkan bahwa terdapat interaksi antara konsentrasi PGPR dan dosis pupuk kotoran kambing terhadap komponen pertumbuhan dan hasil tanaman terung. Aplikasian PGPR dengan konsentrasi 30 ml L-1 dan pupuk kotoran kambing dengan dosis 30 ton ha-1 mampu meningkatkan pertumbuhan diantaranya tinggi, jumlah daun, persentase fruit set, jumlah buah pertanaman, bobot buah pertanaman, panjang buah dan diameter buah pertanaman.
