Abstract

ABSTRAK. Jumlah populasi baik manusia, hewan, tumbuhan berubah setiap waktu. Informasi mengenai jumlah populasi ini dibutuhkan untuk mengetahui keragaman dan kemelimpahan makhluk hidup agar tetap terjaga kelestariannya. Statistika telah mengembangkan sebuah metode dalam mengestimasi jumlah anggota populasi hewan pada populasi tertutup yaitu metode Capture Mark Release Recapture (CMRR) yaitu metode estimasi populasi yang dilakukan dengan cara menangkap, menandai, melepaskan dan menangkap kembali sampel sebagai metode pengamatan populasi.Teknik Capture Mark Release Recapture (CMRR) terdiri dari 3 metode, yaitu metode Licoln-Petersen, metode Schnabel dan metode Schumacher-Eschmeyer. Metode yang paling sederhana dalam Capture Mark Release Recapture (CMRR) adalah metode Licoln-Petersen. Metode Licoln-Petersen merupakan metode yang dilakukan dengan satu kali penandaan (marking) dan satu kali penangkapan ulang (recapture). Karena estimasi yang diperoleh dari metode ini dinilai kurang akurat, maka untuk mengatasi kekurangan tersebut muncul sebuah metode baru yaitu metode Schnabel. Metode Schnabel merupakan metode estimasi jumlah anggota populasi dalam teknik Capture Mark Release Recapture (CMRR) dimana pengambilan sampel dan penandaan sampelnya dilakukan lebih dari dua kali. Dalam penulisan karya tulis ilmiah ini penulis mencoba mengaplikasikan metode Schnabel dalam menghitung populasi ikan mola-mola. Berdasarkan hasil perhitungan diperoleh bahwa estimasi jumlah anggota populasi ikan mola-mola adalah sebanyak 450 ikan.Kata Kunci: Populasi hewan, ikan mola-mola, Capture Mark Release Recapture (CMRR), metode Schnabel.ABSTRACT. The number of human, animal and plant population changes every time.The most accurate method to determine the density of population is by counting the number of the entire individual (cencus), but it is getting hard to conducted due to various constraints such as the natural situation, the locations of research, the funding and the time.Statistics have developed a method to estimate the number of animal populations in the covered population. The technique is Capture Mark Release Recapture (CMRR). The population estimation in this technique is done by capturing, marking, releasing and recapturing sample population as a method of observation.In Capture Mark Release Recapture (CMRR) there is 3 methods, Licoln-Petersen Method, Schnabel Method and Schumacher-Eschmeyer method. Licoln-Petersen is the simplest method in Capture Mark Release Recapture (CMRR). Licoln Petersen is the method which is performed with one marking and one recapture. Because of the estimates obtained from this method was considered less accurate, then to overcome these deficiencies, the method od Schnabel arose. Schnabel method is a method of estimating the number of closed population in Capture Mark Release Recapture (CMRR)  which is sampling and marking more than twice. In writing this paper, the researcher tried to apply Schnabel method in calculating the population of sunfish. Based on the calculations, the estimation number of the sunfish population is 450 fish.Keyword: Animal population, Sunfish, Capture Mark Release Recapture (CMRR), Schnabel Method.

Abstract

Every day waste production is increasing along with the increase in the number of products and people's consumption patterns. What must be done to overcome the increase in waste volume is to reduce the volume of waste from the source through waste management from the community itself. The problem in community participation regarding waste management using the 3R method in Mampari Village, Balangan Regency is what form of community participation in waste management and the level of participation in community waste management. Research on waste reduction using the 3R method in Mampari Village aims to: (1) describe the forms of community participation in Mampari Village. (2) describe the level of participation of the Mampari Village community, data collection includes interviews, observation and documentation, while data analysis uses quantitative descriptive techniques. Based on the research results, one form of community participation in efforts to reduce waste using the 3R method is by providing contributions in the form of energy, goods and money as well as community service and participating in waste management. Apart from that, they also hold community meetings once a month, which are attended by several residents. The level of community participation that occurs in Mampari Village according to the category is low, the only community members who participate are village mobilizers consisting of 10-15 people so that the implementation of waste management is very lacking and still not optimal

Abstract

Optimizing zakat fund distribution services through Islamic financial institutions plays an important role in increasing the effectiveness of zakat management and community empowerment. Although this issue has been widely studied, research that specifically discusses zakat fund distribution services through Bank Syariah Indonesia in the context of rural communities, particularly in Nagari Batu Banyak, remains limited. This study aims to analyze public awareness and understanding of zakat distribution through Bank Syariah Indonesia, identify the factors that influence public trust in the zakat management system, and analyze limited access to services in supporting community empowerment. This study employed a qualitative approach with a case study design, involving informants consisting of Bank Syariah Indonesia representatives, muzakki, and mustahik selected through purposive sampling. Data were collected through observation, in-depth interviews, and documentation, and were then analyzed using the interactive analysis model of Miles, Huberman, and Saldaña, which includes data condensation, data display, and conclusion drawing. The results show that public awareness and understanding of Bank Syariah Indonesia’s zakat services remain low, public trust in zakat management is not yet optimal, and limited access to services is a major factor hindering the optimization of zakat distribution and community empowerment. These findings strengthen studies on zakat service quality and community empowerment from the perspective of Islamic economics. The conclusion of this study emphasizes the importance of improving zakat literacy, transparency in fund management, expanding access to services, and collaboration between Bank Syariah Indonesia, the nagari government, and community leaders to enhance the effectiveness of zakat management. The implications of the study include theoretical contributions to the development of Islamic economics studies and practical implications for Islamic financial institutions in optimizing zakat services based on rural community empowerment.
