Abstract

This study aims to determine the characterization of alluvial soil as a place to grow Chinese betel (peperomia pellucida L.) in Ambon city. Parameters studied included morphological characterization of alluvial soil and description of Chinese betel nut (Peperomia pellucid a L.). The results of observations in the field and analysis of soil samples in the laboratory that have been collected are used as material to identify soil morphological characterization. Meanwhile Chinese betel nut (Peperomia pellucid a L.) collected from alluvial soil was selectively explored by exploring the research area using the Cruise Method. Furthermore, a phytochemical test was carried out to determine its phytochemical content. The results showed that the color of the soil and the rusty color of the alluvial soil in Ambon City was generally brown. The alluvial soil structure at the study site has an O horizon with a soil layer thickness of 17 cm, an A horizon with a thickness of 45 cm soil lumpy structure and a Bw horizon with a soil thickness of 30 cm and the C horizon with a thickness of 65 cm is classified as having a globular lumpy soil structure, It has a high clay and silt content. The lower the soil solum, the lower the C-organic content. The soil in Ambon city has moderate fertility. Low base saturation is associated with low C-organic content in the soil. Chinese sirih that grows on alluvial soil types in Ambon City contains several classes of compounds that are beneficial to health like flavonoids, alkaloids, tripenoids, phenolics, tannins and saponins so that they have ethnomedicin effects such as anticancer, antimicrobial, antidiabetic, antihypertensive and antioxidant activities.

Abstract

This study uses a bibliometric approach to analyze the causes and solutions to climate change. Keyword visualization indicates that recent research has focused on blue carbon and remote sensing as key methods for monitoring climate change. The countries with the highest research contributions are the United States, China, Germany, the United Kingdom, and Australia. Leading authors in this field include Agneta Andersson, Jianfeng Li, Ning Lin, and Marta Marcos. The findings identify the primary causes of climate change, which include greenhouse gas emissions, energy use, land-use change, industry, and transportation, with the highest percentage attributed to energy consumption and natural resource exploitation (35.2%). The use of fossil fuels, coal, gas, and overall energy consumption are identified as major contributors to climate change in coastal regions. As solutions, four main approaches have been identified: adopting renewable energy, sustainable practices, policy and regulatory measures, and environmental restoration. This study concludes that green technologies, supportive policies, and energy efficiency are crucial to mitigating climate change. These findings provide a comprehensive perspective on the causes and solutions to climate change, serving as a valuable reference for global environmental policy formulation.

Abstract

Fertilization of phosphate and lime on ultisol soils will increase the pH of the soil where a high soil pH causes an increase in nutrients. However, the fertilization carried out must pay attention to several things, namely the plants being fertilized, the type of soil, the type of fertilizer used, the dose given, the fertilization time and the method of fertilization. This study aims to obtain information on the effect of phosphate fertilization and liming on ultisol soil on the yield of dry corn (Zea mays L.) and soybean (Glycine max L.(Merr). This research was carried out in Halong Village, Baguala District, Ambon City, which took place from January to May 2024. Soil and plant analysis was carried out at the Soil Laboratory, Faculty of Agriculture, Pattimura University. The experimental design used in this study is a complete randomized design with a factorial pattern with three replicates. The factors studied were P fertilizer and lime, where the parameters studied were the weight of dry seeds, corn kernels and soybeans. The results showed that phosphate fertilization on ultisol soil could increase soil pH which led to an increase in dry seed weight of corn and soybeans and the best combination of phosphate and lime fertilizer dosage on ultisol soil for an efficient increase in dry seed weight of corn and soybean was 92.6 kg P2O5/Ha and 1.5 x Ald.

Abstract

The cation exchange on the adsorbtion complex constitutes an important chemical character of soil in determining soil fertility level. To see which ion that more selective to be separated by NH4+ ion complex absorbtion between Mg and K. The expereiment was done at soil laboratory, faculty of agriculture, pattimura university ambon. The expereiment applied completely randomized desighn. With factorial pattern. NH3 solution treatment consist of 3 hour, 7 and 14 days. the result of the expereiment showed that there was an interaction between NH3 solution treatment and incubation time on the selectivity interchange of Mg-K ion, the availability rate of K and Mg, the change of pH and the conductivity of electricity . the addition of NH3 solution increased soil ph, DHL, Exchangable Mg, exchangeable k, Mg2+ and k+ ions in the soil solution and effected selectivity of Mg-k ion interchange.

Abstract

Penelitian ini bertujuan untuk mengetahui perubahan sifat-sifat kimia pada tanah ultisol pasca pemberian pengapuran dan kotoran kelelawar, serta efeknya terhadap hasil biji kering kacang tanah (Arachis hypogeae L.). Penelitian ini dilaksanakan pada rumah plastik di Desa Ouw, Kabupaten Maluku Tengah, berlangsung dari bulan Oktober 2023 sampai Maret 2024. Analisis sifat-sifat tanah dilakukan di Laboratorium Tanah, Fakultas Pertanian Universitas Pattimura. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Langkap (RAL) berpola faktorial 4 x 4 x 4, dimana parameter yang diteliti adalah pH tanah (H20 1 : 2,5), kemasaman dapat tukar (Aldd + Hdd), Kadar Cadd, Kadar Mgdd dan berat biji kering per tanaman. Hasil penelitian menunjukkan bahwa peranan kapur terutama dalam menaikkan pH tanah dan menurunkan kemasaman dapat tukar (Aldd + Hdd), sedangkan peranan kotoran kelelawar terutama dalam menaikkan kadar Cadd, Mgdd dan hasil biji kering kacang tanah pada tanah ultisol. Selain itu, Hasil setara biji kering kacang tanah terbaik (18,58g / tanaman) diproleh pada taraf kotoran kelelawar 192g per pot tanpa pengapuran pada tanah ultisol dengan pH tanah 5,3 dan kejenuhan Al 66,22%.

Abstract

Indonesia memiliki kekayaan alam berupa keanekaragaman fauna, salah satunya adalah kura-kura. Indonesia merupakan habitat bagi 10% jenis kura-kura air tawar yang ada di seluruh dunia. Penelitian ini bertujuan untuk mendapatkan data morfometrika dari morfologi Turpepel (Cuora amboinensis) yang hidup pada daerah sekitar aliran sungai waibatumerah kelurahan Waihoka, Kecamatan Sirimau, Kota Ambon. Setelah dilakukan penangkapan, Turpepel (Cuora amboinensis) dideskripsikan kemudian dilakukan studi morfometrika yaitu diukur panjang dan lebar karapas (carapace), panjang dan lebar plastron, panjang dan lebar kepala, panjang dan lebar kaki depan, panjang dan lebar kaki belakang, panjang dan lebar telapak kaki depan dan belakang dan panjang ekor. Turpepel yang diteliti merupakan jenis Kura-kura Darat bernama latin Coura amboinensis. Turpepel tersusun atas karapas (carapace) yaitu tempurung atau batok yang keras dengan warna karapas hitam dan plastron yaitu susunan lempengan kulit keras pada bagian perut dengan warna plastron putih kekuningan (krem), memiliki kaki berselaput dan ekor memanjang, namun melebar pada pangkalnya, serta kloaka yang dekat pada pangkal ekor.
