Abstract

Salah satu inovasi model pembelajaran pada penelitian sebelumnya memperlihatkan adanya hubungan yang erat terkait Problems based Learing dengan kemampuan berpikir kritis matematis. Problem Based Learning (PBL) atau dalam bahasa Indonesia yaitu Pembelajaran Berbasis Masalah  merupakan inovasi dalam pembelajaran karena dalam Pembelajaran Berbasis Masalah (PBM) kemampuan berpikir siswa betul-betul dioptimalisasikan melalui proses kerja kelompok atau tim yang sistematis, sehingga siswa dapat memberdayakan, mengasah, menguji dan mengembangkan kemampuan berpikirnya secara berkesinambungan. Penelitian ini dikembangkan melalui analisis bibliometrik data yang diekstraksi dari database Google scholar dengan pengumpulan data menggunakan media Publish or Perish (PoP) dan visualisai data menggunakan VOSviewer. Metadata untuk 300  artikel  model pembelajaran Problem Based Learning pada kemampuan berpikir kritis matematis siswa yang diekstrak dari database Google Cendekia menggunakan perangkat lunak Publish or Perish (PoP). Artikel ini diterbitkan hingga 2022. Kemudian kami menggunakan perangkat lunak VOSviewer untuk melakukan visualisasi jaringan, overlay, dan kepadatan. Hasil yang di dapat berdasarkan data yang terkumpul menyatakan bahwa masih sangat besar kemungkinan untuk memperdalam penelitian terkait Problem Based Learning dan kemampuan berpikir kritis matematis siswa.

Abstract

The sustainable management of mangrove ecotourism requires generating additional income for its managers. One potential strategy is batik training using mangrove ecosystem motifs. On September 15, 2024, a batik training session was conducted for tour guides and managers of the Mangrove Cisiu Eco-Education Park, located in Pangkah Kulon Village, Gresik. The event was attended by 10 participants and was part of the Community Partnership Program (PKM) titled "Empowering Mangrove Managers through Eco-tourism Package Programs as Income Generating for the Sustainability of Mangrove Edupark Management on Cisiu Island", funded by DRTPM Kemendikbudristek. The training was led by Ms. Maria Cecilia, owner of Sanggar Lembayung Batik, who has extensive experience in teaching batik to various communities. Participants learned the basic techniques of batik-making, featuring motifs inspired by the mangrove ecosystem, such as Glodong fish, crabs, and mangrove trees. The training included canting techniques, wax application, and dyeing with synthetic batik dyes. In addition to technical skills, participants gained insight into the potential of batik as a creative economic product that can serve as an additional income source for ecotourism managers. This training aims to support the economic sustainability of the Mangrove Edupark Cisiu by developing high-value batik products, thus contributing to the preservation of the mangrove ecosystem through enhanced livelihoods for the local community.

Abstract

Data mining is a crucial process for extracting valuable information from existing data, which can then be used by companies for quick and accurate decision-making. One of the commonly used methods in data mining is the K-Means Clustering method. In this study, the author applied K-Means Clustering in the retail sector to address the challenges faced by PT. Patria Jaya Mandiri. The author designed an application that can cluster heavy equipment spare parts based on sales data, with the aim of helping the company identify which spare parts are most favored by consumers. This clustering is expected to simplify the process of determining optimal spare part stock, ultimately positively impacting the company’s revenue. The results of this study indicate that heavy equipment spare parts can be categorized into three groups: Most Popular, Popular, and Least Popular. Cluster 1 (Most Popular) consists of 3 data points, Cluster 2 (Popular) consists of 39 data points, and Cluster 3 (Least Popular) consists of 8 data points. This clustering result can serve as a guide for PT. Patria Jaya Mandiri in determining the optimal spare part inventory in the future.

Abstract

Stevia rebaudiana, the source of non-caloric natural sweeteners in the form of steviol glycosides, is a plant with a poor germi- nation rate.Therefore, micropropagation is a potential alternative method to propagate the plants in a large number. Light is an important factor for photosynthesis, so changing the intensity, quality, and duration of lighting can affect plant growth. Photo- period, the duration of light within 24hour period, has been known to influence the growth of S. rebaudiana grown in ex vitro conditions. The purpose of this study is to investigate the effect of various photoperiod (8, 12, and 16 hours) on the growth of S. rebaudiana in vitro. The node segments from ex vitro grown S. rebaudiana plants were cultured on solid MS media supple- mented with 1.13mg/L BA and 0.35 mg/L IAA. The shoots were rooted on solid half-strength MS media containing 0.1 mg/L IAA. For acclimatization, therooted shoots were grown on a mixture of fertile soil, burnt rice husk, cocopeat, and manure. The photoperiod treatment was applied from the beginning to the end of the experiment. Our results showed that the highest shoot length was found under 16 hour photoperiod. On the otherhand, root number and root length were not affected by photoperiod. Additionally, a 16 hour photoperiod increased shoot length (5.9 cm) compared to a 12-hour (3.48 cm) and 8-hour photoperiod (3.08 cm) after 5 weeks of acclimatization. A 16 hour photoperiod also producedhighest total leaf fresh weight (0.2 g). Howev- er, different photoperiods did not significantly affect leaf number and leaf area. In conclusion, 16 hour photoperiod is the best condition for S. rebaudiana micropropagation.

Abstract

Mikroplastik memiliki potensi tinggi untuk tersebar merata di perairan dan terakumulasi pada organisme perairan termasuk ikan. Saluran pencernaan dan organ insang merupakan bagian ikan yang seringkali terkontaminasi oleh mikroplastik. Penelitian ini bertujuan untuk menganalisis komposisi mikroplastik pada ikan Clupea harengus, Euthynnus affinis, dan Restrelliger brachysoma dengan lokasi yang berbeda diantaranya Pondok Dadap Sendang Biru, Pacitan, dan Mayangan Probolinggo. Analisis dilakukan dengan identifikasi organ dan saluran pencernaan pada ketiga spesies ikan. Komposisi mikroplastik pada sampel organ ikan dianalisis dengan menghancurkan bahan organik melalui perendaman sampel pada laruta H2O2 30% dan larutan Fe (II) 0,05 M selama 24 Jam. Analisis dilanjutkan dengan penyaringan sampel menggunakan kertas Whatman dan identifikasi menggunakan mikroskop (Olympus CX33). Diantara jenis mikroplastik, fiber dan fragmen merupakan jenis mikroplastik yang paling banyak ditemukan pada ikan Clupea harengus, Euthynnus affinis, dan Restrelliger brachysoma dibandingkan dengan jenis film.  Kelimpahan total mikroplastik ditemukan lebih tinggi pada organ dibandingkan pada saluran pencernaan.  Terdapat perbedaan jumlah kelimpahan mikroplastik pada ketiga spesies. Spesies Clupea harengus memiliki kelimpahan mikroplastik tertinggi dibandingkan dengan spesies lainnya. Hal ini dipengaruhi oleh kondisi ikan yang tidak dapat membedakan antara mikroplastik dan plankton sebagai mangsanya. Kebiasaan makan ikan dengan menyaring air di sekitarnya membuat ikan rentan mendapatkan plankton yang terkontaminasi mikroplastik.   Microplastics have a high potential to be evenly distributed in waters and accumulate in aquatic organisms including fish. The digestive tract and gill organs are parts of fish that are often contaminated by microplastics. This study aims to analyze the composition of microplastics in fish Clupea harengus, Euthynnus affinis, and Restrelliger brachysoma with different locations including Pondok Dadap Sendang Biru, Pacitan, and Mayangan Probolinggo. The analysis was conducted by organ identification in the three fish species. The composition of microplastics in fish organ samples was analyzed by destroying organic matter through immersion of samples in 30% H2O2 solution and 0.05 M Fe (II) solution for 24 hours. The analysis was continued by filtering the samples with Whatman paper and identifying them with a microscope (Olympus CX33). Among the types of microplastics, fibers and fragments were the most common types of microplastics found in Clupea harengus, Euthynnus affinis, and Restrelliger brachysoma compared to film types.  The total abundance of microplastics was found to be higher in organs than in the digestive tract.  There were differences in the abundance of microplastics among the three species. Clupea harengus species had the highest abundance of microplastics compared to other species. This is influenced by the condition of the fish, which cannot choose between microplastics and plankton as prey. Fish feeding habits by filtering the surrounding water make fish vulnerable to plankton contaminated with microplastics.
