Characteristics of Compost from Straw and Fisheries Waste: A Comparative Analysis of Different Decomposers
Get PDFThe objective of this research was to assess the efficacy of three different decomposers in producing compost of high quality that meets the compost maturity standards (SNI 19-7030-2004). The experimental study was conducted with three treatments, each replicated five times, resulting in a total of fifteen composting holes. The research was conducted in South Batu Kuta Village, Narmada District, West Lombok Regency, from October to December 2019. The treatments included D1 (EM4 decomposer), D2 (Promi decomposer), and D3 (Phosphate Solubilizing Bacteria (PSB) decomposer). Various parameters, such as color, smell, temperature, pH, C-Organic, Total N, and C:N ratio, were assessed. The findings demonstrated that all three decomposers effectively decomposed the compost, yielding a high-quality product suitable for various plant applications. The compost produced by EM4, Promi, and PSB decomposers exhibited characteristics such as a blackish color, soil-like smell, a temperature ranging from 29.2°C to 29.8°C, a pH ranging from 6.83 to 6.87, organic carbon content ranging from 12.87% to 14.73%, total nitrogen content ranging from 0.83% to 0.87%, and a C/N ratio ranging from 14.35% to 14.60%. These results align with the compost maturity standards specified in SNI 19-7030-2004
Feasibility and Added Value of the Robusta Coffee Agroindustry in Kebun Tebu District, West Lampung
Get PDFThe study aims to identify the characteristics of the ground coffee industry products, feasibility, and the added value of ground coffee in the Kebun Tebu District of West Lampung. The research method that the ground coffee industry will use in the Kebun Tebu sub-district uses qualitative descriptive analysis to identify the feasibility of the ground coffee business using the R/C and B/C ratio indicators, and the amount of added Value resulting from ground coffee processing is calculated using the Hayami method. The research results show that Coffee bean processing activities are financially feasible for the West Lampung Kebun Tebu industry to undertake and continue. They are also feasible for the community because they are economically profitable. Feasibility analysis based on the R/C and B/C ratio indicators shows that the ground coffee business with honey and natural processes has R/C > 1 and B/C > 0 or is worthy of business. The added value resulting from natural and processed ground coffee honey is classified as having a high value-added ratio because the Value added ratio is >40 percent, and processing ground coffee is a capital-intensive activity
Peningkatan Kualitas Sumber Daya Manusia di Rumah Atsiri Indonesia Melalui Penyusunan Modul Pelatihan Bilingual: Improving the Quality of Human Resources in Rumah Atsiri Indonesia through Bilingual Training Module Arrangement
Get PDFRumah Atsiri Indonesia (RAI) as a tourist destination that carries the concept of integrated destination, has a mission to educate the public about the history of essential oils and essential plants that can be used for various purposes. In an effort to provide this information to all visitors, RAI is committed to providing comprehensive information to all visitors, both local and foreign tourists. The increasing number of foreign tourists requires RAI's human resources, especially educators, to improve their competence in English. The Community Service Programme (PKM) carried out by the English for Creative Industries Research Group from the D-3 English Study Programme, Vocational School, UNS, with the title Improving the Quality of Human Resources at Rumah Atsiri Indonesia through Bilingual Training Modules Arrangement, is expected to be a solution to this problem. This PKM activity is carried out in several stages of work: first, the analysis of partner needs; second, the process of translating existing modules into English; third, the arrangements of modules in two languages; and last, the overall program evaluation. The translation process refers to the stages of translation by Nida and Taber, as well as translation techniques by Molina and Albir. The results of the translation are then compiled in the form of bilingual modules that can be studied independently by RAI’s human resources.

Utilizing a systematic literature review, we analyze existing frameworks and theories related to publicity materials, with a specific focus on their application in educational settings for undergraduate students learning English for Professional Communication. By synthesizing insights from seminal works and contemporary studies, this paper equips educators, students, and practitioners with a robust understanding of the principles, best practices, and innovative approaches for creating impactful publicity materials. Our findings highlight the evolution of publicity materials, the integration of digital platforms, personalization strategies, data analytics, and ethical considerations. These insights offer practical guidance for enhancing educational and professional development curricula, ensuring the effective use of publicity materials in various contexts
Study of quality of cows milk treated bay leaf teat dipping in Tegal Mandiri Farmer
No full textThe aim of this study was to examine the quality of milk including microbiological, chemical properties and detection of subclinical mastitis resulting from the application of bay leaf solution as a natural antiseptic. Application of bay leaf solution was conducted on dairy cows at Tegal Mandiri Farmer Group for 28 days. The parameters observed include microbiological and chemical quality including Total Plate Count (TPC), Staphylococcus aureus contamination, Escherichia coli contamination, fat, protein, lactose content, density and freezing point. Subclinical mastitis was detected using the Draminski Mastitis Detector to see the electrical resistance value of the milk. The results showed that the milk resulting from the application of teat dipping with bay leaf solution had microbiological qualities including Total Plate Count and S. aureus population which met the standards with a TPC population of 4.70 log CFU/ml and S. aureus 0.91 log CFU/ mL, but the E. coli population did not meet the standards. Application of teat dipping with bay leaf solution can reduce the population of S. aureus. Chemical quality in the form of fat content, protein, specific gravity, lactose and freezing point is in accordance with standards. An electrical resistance value of >300 indicates that the milk is of high quality, healthy and has a low incidence of mastitis
Penyusunan Konsep Sustainable Village Melalui Analisis Anggaran Pendapatan dan Belanja Desa di Kabupaten Jember
Get PDFThis article is designed to develop the concept of a sustainable village through an in-depth exploration of the Village Revenue and Expenditure Budget (APBDes) in Jember Regency. The primary focus of this research is to understand how Village Funds can be configured to support the concept of a Sustainable Village. This study uses descriptive quantitative analysis methods by processing APBDes data from 223 villages in Jember Regency to form the concept of a sustainable village. The results indicate that villages allocating funds with a priority on infrastructure spending, such as Yosorati, Mulyorejo, and Darungan, are more likely to implement the concept of a sustainable village compared to villages with lower allocations in the same category. This article highlights the importance of integrating sustainability principles into the planning and budgeting of Village Funds to ensure that development not only improves current living quality but also preserves the environment for the future

Implementation of Differentiated Learning in English Lesson Using Independent Curriculum at MAN Surabaya
Get PDFThis study explores differentiated learning in English classes at MAN Surabaya within the Independent Curriculum framework. Differentiated learning adapts teaching strategies, content, and assessments to meet students' varying needs, readiness levels, interests, and learning profiles. The research identifies strategies used by the teacher, student preferences, and implementation challenges. Using qualitative methods such as observations, interviews, and document analysis, the study finds that the teacher employs flexible grouping, tiered assignments, and individualized instruction to cater to diverse student needs. Students favor activities aligned with their interests and readiness, finding them more engaging and effective. However, challenges include limited resources, time constraints, and the need for ongoing professional development.
