Penelitian ini bertujuan untuk mengetahui pengaruh tumbuhan liar berbunga terhadap keanekaragaman, kemerataan, kekayaan, dan dominansi musuh alami pada ekosistem tanaman tebu. Kegiatan penelitian dilaksanakan pada bulan Desember 2021 – April 2022 di lahan tanaman tebu di Instalasi Penelitian dan Pengkajian Teknologi Pertanian (IP2TP) Balai Penelitian Tanaman Pemanis dan Serat (Balittas), Karangploso, Malang. Penelitian ini menggunakan metode deskriptif kuantitatif dengan perangkap berupa yellow sticky trap dan farmcop. Hasil penelitian dianalisis menggunakan Indeks Keanekaragaman (H’), Indeks Kemerataan (E), Indeks Kekayaan (R), Indeks Dominasi (D), dan menggunakan Uji T dengan taraf kesalahan 5%. Hasil penelitian didapatkan sebanyak 16 jenis musuh alami pada lahan tebu dengan tumbuhan liar berbunga dan 9 jenis musuh alami pada lahan tebu tanpa tumbuhan liar berbunga. Indeks keanekaragaman pada lahan tebu dengan dan tanpa tumbuhan liar berbunga memiliki nilai H’ termasuk kategori sedang, nilai E termasuk kategori hampir merata, nilai R termasuk kategori rendah, dan nilai D kategori rendah. Berdasarkan hasil Uji T terdapat perbedaan rerata populasi musuh alami pada lahan tebu dengan dan tanpa tumbuhan liar berbunga yang berbeda nyata (t hitung > t tabel) yaitu t hitung sebesar 6,343 dan t tabel 2,144.

Abstract. This study investigates the determinants of e-Commerce adoption as well as their impact to the performance of MSMEs in Medan City. This research is a quantitative study using primary data collected through surveys with questionnaires. The sample technique used is random sampling resulting in 222 respondents. Empirical model is estimated using regression. Results show that all constructs simultaneously influence e-commerce adoption and e-adoption have a significant positive effect on performance improvement. Partially, organizational willingness and technological willingness have a significant and positive effect on e-commerce adoption, while the external environment has a positive but not significant on improving the performance of MSMEs in Medan City. This research contributes to provide input and description related to the adoption of e-commerce adoption. It can be used as a basis for removing barriers to e-commerce utilization which then could improve performance of MSMEs. Improving financial performance which is one element of performance eventually lead to increasing in profits. Keywords. Adoption of Information Technology; Micro Small and Medium Enterprises; MSMEs; Online Business. Abstrak. Penelitian ini menguji determinan adopsi e-Commerce serta dampaknya pada peningkatan kinerja pada UMKM di Kota Medan. Penelitian ini merupakan penelitian kuantitatif menggunakan data primer yang dikumpulkan melalui survey dengan kuisioner. Teknik sampel menggunakan random sampling sebanyak 222 responden. Model empiris diuji dengan menggunakan regresi. Hasil penelitian menunjukkan secara serempak seluruh konstruk berpengaruh pada adopsi e-commerce dan adopsi e-commerce berpengaruh positif dan signifikan pada peningkatan kinerja. Secara parsial kesediaan organisasi dan kesediaan teknologi berpengaruh positif signifikan terhadap adopsi e-commerce, sedangkan lingkungan eksternal berpengaruh positif namun tidak signifikan terhadap peningkatan kinerja UMKM di Kota Medan. Penelitian berkontribusi untuk memberikan masukan dan gambaran terkait diterminan adopsi e-commerce. Ini akan menjadi dasar dalam menghilangkan penghambat dalam pemanfaatan e-commerce yang kemudian dapat meningkatkan kinerja UMKM. Peningkatan kinerja keuangan yang merupakan salah satu unsur kinerja yang akan meningkatkan laba.

Small island ecosystems and their inhabitants face a significant threat from global warming, jeopardizing their sustainability. These communities are particularly vulnerable to the impact of climate change, as they heavily rely on natural resources for their livelihoods and are more vulnerable than mainland regions. Therefore, it is essential to take urgent action to address the challenges small island states face and promote their resilience in the face of climate change. To preserve the coastal ecosystems in Karimunjawa Islands, Indonesia, this study proposes an alternative spatial plan through micro-zonation analysis. The study conducted literature reviews and field surveys to collect data and develop recommendations for the current spatial plans through spatial, descriptive statistics, and comparative analysis. The findings show that the sea surface temperatures of Karimunjawa and Kemujan Island have increased by 1-2 ℃. Stress levels were found for coral reefs at the bleaching warning position for all Karimunjawa Island marine areas, including Kemujan Island. Legon Lele and Tanjung Gelam were found to have suspended sediment traces and indications of heavy metal contamination, making them the research focus. The Karimunjawa micro-zonation boundaries were obtained, especially in the Legon Lele and Tanjung Gelam areas, with an area of 640.63 and 817.45 ha, respectively. The proposed micro-zonation for Karimunjawa National Park refers to watershed-sedimentary cells, making it an example of implementing integrated coastal management (ICM) spatial boundaries in Karimunjawa and other nations. By applying this micro-zonation, coastal ecosystem rehabilitation efforts can be carried out precisely., (© 2023. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)
