Abstract

This study aimed to formulate and evaluate an NPK compound fertilizer with a target ratio of 10:6:20 to enhance green mustard (Brassica juncea) productivity. At CV Tabita Jaya, standardized production methods were used to prepare the fertilizer by mixing Urea, triple superphosphate, and potassium chloride, with analytical confirmation of the nutrient content. Results showed nitrogen (N) content of 10.8%, phosphorus (P₂O₅) at 6.5%, and potassium (K₂O) at 20.8%, closely aligning with the target formulation. Moisture content was low at 2.48%, ensuring product stability and ease of application. Analytical techniques employed included Kjeldahl titrimetry for nitrogen, molybdate-vanadate spectrophotometry for phosphorus, and flame photometry for potassium. These methods demonstrated high reliability, with parameters such as repeatability, reproducibility, and recovery meeting international standards. The fertilizer is expected to support green mustard growth by enhancing critical metrics, including plant height, leaf number, and biomass accumulation. The study highlights the agronomic benefits of balanced NPK fertilization for green mustard, emphasizing enhanced nutrient absorption and sustainable agricultural practices. Furthermore, integrating this fertilizer with organic amendments may help mitigate potential soil degradation associated with prolonged use of inorganic fertilizers. The findings highlight the potential of precision-formulated fertilizers to enhance crop productivity while promoting environmental sustainability.

Abstract

This study aims to determine the feasibility of SETS (Science, Environment, Technology, And Society) based modules on colloidal system, determine student learning outcomes after using SETS-based modules in learning and student responses to the modules. This study uses a 4-D development model consisting of define, design, development, and dissemination. This research was conducted at SMA Negeri 11 Medan which was carried out for 7 months. The feasibility of module was seen through a feasibility questionnaire for media and material experts based on the BSNP standard with a Likert scale of 1 to 5. Validation data obtained from media and material experts on SETS-based modules obtained an average percentage of 83.58% with the category valid/worthy. Student learning outcomes were obtained through the calculation of N-Gain test, which was equal to 0.74 in the high category and the average posttest score of students was 84.67. Student responses to the SETS-based module obtained an average percentage of 91.24% with a very high questionnaire interpretation. Based on the results obtained by the researcher, it can be concluded that this SETS-based module is appropriate for use in colloidal learning with a high student learning success rate and student responses that fall into very good criteria.

Abstract

One of the supporting efforts in the tourism sector is the culinary business because it can attract tourists to visit a tourist destination. In this regard, consumption, especially of local or traditional foods and beverages from a region, is seen as food with cultural values. Food is both a physical need and a cultural and social activity. Therefore, the objective of this research involves the role of gender as a moderation factor in the intention to consume traditional foods, considering factors such as attitude, subjective norm, and perceived behavior. This study involves students as tourist participants who prefer culinary tourism destinations they have visited. The research employs Structural Equation Modelling (SEM) analysis, utilizing Amos in this study. The research findings indicate that the moderating role of gender shows that gender does not moderate attitudes and subjective norms concerning the intention to consume traditional foods. However, it moderates perceived behavior regarding the intention to consume traditional foods.

Abstract

Mitra kegiatan ini adalah Usaha bersama Arang Batok di desa Patumbak Dua dusun IV kabupaten Deli Serdang. Dipimpin oleh Bapak Burman Siagian mulai beroperasi sejak tahun 2020 memiliki pekerja tetap 3 orang. Selama ini, pembakaran arang batok hanya menghasilkan arang sebagai produk utama, sementara potensi limbah asap yang dihasilkan belum dimanfaatkan secara optimal dan menjadi limbah yang menimbulkan dampak negatif. Padahal Konversi limbah asap arang batok menjadi produk yang mempunyai nilai ekonomi dan memiliki manfaat yang begitu banyak yakni: Pengawet Makanan Alami Pengendalian Hama pada industri pertanian, dan dapat digunakan dalam proses pengolahan limbah untuk mengurangi bau tidak sedap. Melalui kegiatan PKM penerapan teknologi destilasi pirolisis, asap hasil pembakaran arang batok dapat ditangkap, diolah, dan dikondensasi menjadi asap cair. Tim pengabdian memperkenalkan konsep sains techno dengan mengintegrasikan prinsip dasar kimia dan teknik pengolahan hasil pembakaran. Kegiatan pada Mitra IRT Arang batok diawali dengan Sosialisasi dan pelatihan; bagi mitra untuk meningkatkan pengetahuan dan Ketrampilan SDM dalam pengolahan asap pembakaran menjadi produk asap cair. Selanjutnya pelatihan pembuatan dan penerapan alat TTG Pirolisis kondensasi. Hasil kegiatan menunjukkan bahwa pengetahuan dan ketrampilan SDM dalam pengolahan asap pembakaran menjadi asap cair meningkat, Sebelum kegiatan hanya 1 orang yang mengetahui pengolahan asap cair setelah kegiatan 3 orang pekerja mengetahui (>100%). Sebelum kegiatan hanya memproduksi arang batok, dengan menggunakan TTG pirolisis kondensasi diperoleh pengolahan asap pembakaran menjadi produk asap cair dengan rendemen (40%) atau 40 kg dari pembakaran 160 kg batok kelapa grade 3. Diversifikasi produk membuat peningkatan jumlah tenaga kerja dari 3 pekerja menjadi 4-5 orang. Ada penambahan 2 orang pekerja untuk pengoperasian alat dan produk asap cair. Dengan adanya pengolahan asap pembakaran arang batok maka perekonomian dapat meningkatkan pendapatan dan kesejahteraan mitra (IRT Usaha Bersama Arang Batok) dan kesehatan masyarakat sekitar.

Abstract

Purpose - This study aims to examine the language attitudes of the Balikpapan community toward regional languages and to explore how these attitudes may influence regional identity and tourism development in the context of the new capital city (IKN) expansion. Method - A quantitative approach was employed, collecting survey data from 384 respondents with a 5% margin of error. Multiple factors influencing language attitudes—environmental, instructional (Indonesian as the language of instruction), family, media, and institutional factors—were analyzed using significance testing to determine their predictive effects. Findings - The results show that environmental factors (Sig. = 0.000) and media/institutional factors (Sig. = 0.029) exert significant positive effects on regional language attitudes. Conversely, the use of Indonesian as a language of instruction (Sig. = 0.012) has a significant negative effect. Family influence (Sig. = 0.533), although theoretically assumed to be the strongest factor, shows no significant impact in shaping respondents’ attitudes. Overall, the Balikpapan community demonstrates attitudes toward regional languages that could be strengthened through targeted interventions such as education-based initiatives, regional language promotion, enhanced family engagement, and the creation of language-friendly public spaces. Originality/Value - This study contributes novel empirical evidence on the sociolinguistic dynamics of a rapidly developing urban area located near the emerging national capital. It highlights how regional language attitudes intersect with cultural identity and tourism development, offering practical insights for policymakers seeking to preserve linguistic heritage while promoting culturally grounded tourism in the era of IKN development.
