The enzymes laccase (Lac), manganese peroxidase (MnP), and lignin peroxidase (LiP) are ligninolytic enzyme groups that have a crucial role in degrading lignin compounds. These complex components are abundant in plant biomass. This research aims to isolate and characterize microorganisms producing the enzymes Lac, MnP, and LiP from leaf litter, rhizosphere soil, and sediment in the Gunung Lumut Protected Forest (GLPF) and Sungai Wain Protected Forest (SWPF), East Kalimantan. The bacterial and fungal isolates obtained were cultured on NA and PDA media enriched with 0.05% guaiacol as a substrate. Initial selection was carried out based on the colony growth rate and the formation of a brownish discoloration zone, which indicates ligninolytic enzyme activity. The superior isolates were then tested for extracellular enzyme activity quantitatively using a UV-Vis spectrophotometer. Among the bacterial isolates, the highest Lac activity is isolated GLS 5.1.2 (173.44 U L-1); the highest MnP activity is isolated GLS 5.3 (177.41 U L-1); and the highest LiP activity is isolated GLS 5.1.2 (1034.05 U L-1). In the group of fungi, isolate SS2 was detected with the highest Lac activity (20.66 U L-1), MnP activity (333.75 U L-1), and LiP activity (2516.13 U L-1). Biodiversity sources in the Gunung Lumut Protected Forest (GLPF) and Sungai Wain Protected Forest (SWPF), East Kalimantan have the potential to produce microbial isolates with unique enzymatic characteristics that have never been reported before. The resulting microbial isolate can be used as a bioactivator in composting organic waste to produce high-quality organic fertilizer.

The Center for Teaching and Learning Activities (PKBM) is one of the non-formal educational institutions that has a strategic role in improving the quality of human resources through various learning programs. PKBM provides a variety of educational services such as equality education, skills training, and various kinds of community empowerment programs. For sustainability and effectiveness, the program is highly dependent on effective and efficient financing management. The purpose of the study is to describe the characteristics of sources and Revenue Budget Plans (RAP) in PKBM Karya Bhakti Punung, to describe the characteristics of financial realization and accountability in PKBM Karya Bhakti Punung. The method used in this study is data description with an ethnographic approach. Data collection used interview techniques with selected resource persons. The results obtained from this study are known if the sources of funds contained in PKBM Karya Bhakti are obtained from the government, namely from the Director General of PNFI (Indonesia Non-Formal Education), the East Java Provincial Education Office, and the Pacitan Regency Education Office, in addition to that the sources of funds are obtained from independent or independent institutions and businesses from PKBM itself. By diversifying funding sources and optimizing the use of funds, PKBM can reduce dependence on one source of funding, thereby increasing operational stability and financial sustainability. Good management also allows greater access to resources, which can be used to improve the quality of education and services, as well as develop more relevant and innovative programs and curricula. The active participation of the community in the financing management process will strengthen the relationship between PKBM and its community, as well as encourage greater support. Seeing this, additional funds are needed for PKBM so that educational activities can run as well as possible.

Infertility, according to the World Health Organization (WHO), affects approximately 8-12% of couples of reproductive age worldwide. In Indonesia, its prevalence ranges from 10-15%, meaning about 4-6 million couples require treatment to conceive. The incidence of infertility is influenced by various factors, including access to and the quality of healthcare services. Therefore, healthcare providers’ knowledge and awareness of infertility play a crucial role in its management, leading to early detection and appropriate referrals to advanced healthcare facilities. Given the limited access to information and healthcare services in remote areas, educating and promoting early detection of infertility by healthcare providers is essential to improving healthcare quality in those regions. This community service activity aims to enhance healthcare workers' understanding of diagnosing infertility, ensuring that patients are promptly referred for further treatment. The activity took place on Friday, November 15, 2024, via Zoom Meeting, in collaboration with an experienced OB/GYN doctor in Kupang. A total of 27 participants attended, consisting of 20 people from Bakunase Health Center and 7 people from Sikumana Health Center.

The electoral system is a form of representative democracy which can be understood as a means of distributing power to the people. In general, there are three types of electoral systems implemented throughout the world, namely majority systems, proportional systems and mixed systems. However, this article only discusses open and closed elections, each of which has its own advantages and disadvantages. This article aims to analyze the open and closed proportional electoral systems in Indonesia.

Abstrak:
This article defines the process for developing a speaking syllabus for flight attendant school in a Flipped Learning Network (FLN), which increases student engagement and learning by assigning watching videos at home followed up in pre-teaching discussions, and requiring the students to work on live practices in face-to-face classroom activities. Considering that the syllabus is designed to develop the students' oral competence, the target speaking skill is aimed toward developing students' ability to engage in procedural communication in the workplace. Therefore, the topics/themes are chosen to meet the needs of flight attendants consistent with Project-Based Learning (PBL) by Forum Group Discussions (FGDs). In order to achieve this objective, the development of a syllabus begins with a need analysis, topic selection, syllabus prototype production, expert evaluation, and revision for the final product. The syllabus is organized such that the learning experience is explicitly stated for two formats: online meeting (through Google Classroom for the video analysis) as the lecture homework for pre-discussions followed by classroom face-to-face meeting (through FGDs with peers, individual work, and the teacher) to comprehend students' understanding though some units. Each unit has 2 (two) topics. Each topic consists of 60 (sixteen) minutes or 1 (one) meeting. This syllabus development is considered to be implemented in terms of FLN for instructional activities in flight attendant school resulting higher-order thinking skills such as collaboration, design and problem solving as students tackle difficult problems, work in groups, research, and construct knowledge with the help of the teacher and peers.
