Jamur tiram adalah jamur yang dapat dimakan, yang tidak hanya lezat dalam rasa tapi juga kaya akan nutrisi. Jamur Tiram merupakan komoditas utama di Sukoharjo. Permasalahannya adalah bagaimana menerapkan strategi bagi para pembudidaya untuk meningkatkan varietas produk jamur tiram. Salah satu upaya yang dilakukan adalah dengan mengeringkan dan mengolahnya menjadi tepung jamur tiram. Berkaitan dengan permasalahan tersebut, dilakukan perancangan dan penerapan alat pengering energi surya (solar dryer). Alat pengering energi surya yang diimplementasikan mampu mengeringkan 5-10 kg jamur tiram segar dalam waktu 50 -72 jam. Untuk memproses tepung jamur tiram, digunakan penggiling makanan (food grinder) yang telah terbukti efektif untuk industri skala kecil dan menengah (300 kg per bulan) dengan investasi yang rendah dan juga mudah digunakan. Untuk metode sosialisasi dan pelatihan pengeringan dan penepungan jamur tiram, disiapkan modul pelatihan dan video yang berisi Standar Prosedur Operasional (SOP) proses produkdi alat pengering surya, dan juga proses pengeringan serta penepungan jamur tiram.

Proses pengeringan rimpang jahe yang dilakukan petani Biofarmaka Karanganyar untuk memproduksi simplisia, Â selama ini menggunakan sumber panas sinar matahari. Sinar matahari merupakan sumber energi yang terdapat bebas di alam namun tidak dapat dikontrol. Proses produksi simplisia terhambat apabila tidak terdapat panas matahari yaitu apabila cuaca mendung atau hujan. Hambatan proses produksi simplisia menjadi faktor yang penting mengingat daya tahan jahe segar yang rendah. Untuk itu, diperlukan adanya alternatif sumber energi panas yang murah dan dapat dikontrol untuk memproduksi simplisia jika sumber energi panas matahari tidak dapat digunakan. Penelitian ini bertujuan untuk menyusun konsep perancangan alat pengering simplisia jahe menggunakan sumber panas sinar matahari dengan backup panas kompor biomassa. Tahapan perancangan terdiri dari identifikasi kebutuhan pengguna, penyusunan spesifikasi produk, pengembangan konsep produk, dan pemilihan konsep produk. Penelitian ini menghasilkan 36 konsep produk untuk alat pengering simplisia jahe menggunakan sumber panas sinar matahari. Â Kata kunci : alat pengering; simplisia; energi matahari; kompor biomassa Â Abstract Â The ginger drying process used by Biofarmaka farmers of Karanganyar to produce simplisia, used heat source from solar energy of the sunlight. Sunlight is a free source of energy that can be obtained in the universe but can not be controlled. Production of simplisia can be stopped or obstructed if there is no sunlight that gives solar energy for the drying process (cloudy or rainy). This obstacle of production process of simplisia becomes an important matter considering the low durability of fresh ingredients (ginger). This requires the presence of an additional source of heat energy which is cheap and can be controlled to produce simplisia if the heat source from solar energy of the sunlight can not be used. This study aims to construct concept of design solar dryer with a biomass stove for heat backup to produce ginger simplisia. The step of design are identification of user requirements, construction of product specifications, product concept development, and product concept selection. This study resulted in 36 product concept of the ginger solar dryer. Keywords : dryer; simplisia; solar energy; biomass stove

Indonesia was one of the countries affected by the COVID-19 pandemic. This condition encourages the implementation of various policies, including online learning for students to prevent the spread of the virus. Unfortunately, students have difficulties with this learning system. Therefore, this research aims to analyze the condition factors that support learning performance for university students in Indonesia, namely Task-Technology Fit (TTF), Technology-Induced Engagement (TIE), and Technology-Induced Motivation (TIM). Demographic factors, such as location and gender, were also considered in the analysis. Learning success is assessed from the student's Grade Point Average (GPA) during one semester of online lectures. Data collection was carried out using an online questionnaire strategy, which succeeded in reaching 40 valid respondents. The fuzzyset Qualitative Comparative Analysis (fsQCA) method was used to analyse the configuration model for student online learning success. This research succeeded in formulating six combinations of factor conditions that were sufficient to achieve online learning success. Successful online learning includes whether it was related to gender or not, as well as the location of the student's home, and a combination of other factors. Three combinations of conditions that must exist in every successful configuration of student online learning in Indonesia are, urban study location, students having a high TIE, and also a high TIM. The results of this study contribute to lecturers and higher education management regarding the conditions that need to be prepared to support the success of students' online learning.

The Center for Research and Development of Technology and Industrial Collaboration, which is part of the Sebelas Maret University Research and Community Service Institute (PKPTKI LPPM UNS) in 2023, requires the development of an agency website for the dissemination and distribution of information to the public. \textbf{The main objective} is to provide information on research products and services that need to be promoted to the wider community. This website is expected to support the socialization of research results, PKPTKI member consultation services, and collaboration results and other activities. Through qualitative research using primary data obtained through Forum Group Discussion (FGD), this research produced a bilingual PKPTKI website. The SWOT (Strength, Weakness, Opportunity, Threat) analysis process was carried out through brainstorming activities with 4 members and 6 PKPTKI partners, and the results were used to map website needs, technical design and website content, and overall evaluation. The strategies resulting from the SWOT analysis involve developing a backend system to improve the PKPTKI website in English, scheduling consistent content updates, coordinating with the UNS ICT unit for website security, and preparing administrative SOPs for risk mitigation. The final result of this study is an effective PKPTKI website for widespread information dissemination and supporting interaction with various parties, including industry partners, practitioners, and national and international researchers.

The study explores the dual impacts of tourism in the religious sector, highlighting both its positive contributions and environmental challenges when sustainability principles are disregarded. A literature review employing the PRISMA method examined 55 articles from SCOPUS-indexed journals published between 2014 - 2024, resulting in 27 relevant articles on the sustainable religious tourism field. Findings underscored that religious tourism generates social, economic, and environmental impacts. A comprehensive management framework is advocated for sustainable religious tourism, necessitating collaboration among stakeholders. Central to this approach is balancing the interests of all stakeholders to mitigate conflicts of interest effectively. The study recommends formulating and implementing a religious tourism sector strategy. This involves defining management concepts, executing strategies, and enforcing supervision mechanisms to foster sustainable practices.

Purpose: This study aims to develop a Muzakki loyalty model through a systematic literature review (SLR) approach. Methodology: The SLR process was conducted using the PRISMA scheme to select relevant literature form the Scopus database. Out of 27 identified articles, 6 were selected for further analysis. Results: The findings show that service quality affects Muzakki satisfaction, while personal factors, such as sharia governance and transparency in zakat management influence trust and Muzakki loyalty. Islamic work ethics and trust, also play a significant role in increasing loyalty and the amount of zakat contributions. Applications/Originality/Value: This study highlights the importance of effective zakat management by considering the dimensions of Muzakki loyalty to enhance sustained participation in zakat payments. The findings contribute to the broader discourse on sustainable development and highlight the potential applicability of these principles to other sectors. By applying these insights, industries and organizations can adopt similar strategies to ensure longterm sustainability and stakeholder engagement.
