Abstract

Tumbuhan paku adalah tumbuhan perintis yang dapat ditemukan di setiap tipe kawasan hutan dan memegang peranan penting dalam menyusun ekosistem hutan. Kawasan hutan dapat mengalami perubahan fungsi yang antara lain diakibatkan oleh perbedaan kondisi di tepi hutan dengan di dalam hutan. Dampak dari bertemunya dua kondisi lingkungan yang berbeda tersebut terhadap tumbuhan dan hewan dapat disebut efek tepi (edge effect). Penelitian dilakukan di Cagar Alam Bantarbolang Pemalang, Jawa Tengah. Tujuan dari penelitian ini untuk mengetahui keanekaragaman dan faktor lingkungan tumbuhan paku terestrial di Cagar Alam Bantarbolang. Data yang diperoleh dianalisis menggunakan Indeks Nilai Penting (INP), Indeks Keanekaragamaan (H’) Shannon-Wiener, Indeks Kemerataan Spesies (e), dan Indeks Kesamaan Komunitas (IS). Hasil penelitian di Cagar Alam Bantarbolang diperoleh tumbuhan paku terestrial sebanyak 10 spesies yang terdiri dari 400 individu termasuk dalam 6 familia. Spesies yang paling banyak ditemukan yaitu Stenochlaena palustris dengan 205 individu. Cagar Alam Bantarbolang dipengaruhi oleh efek tepi, karena semakin ke dalam hutan jumlah spesies tumbuhan paku terestrial semakin sedikit. Faktor lingkungan yang berpengaruh terhadap jumlah spesies tumbuhan paku terestrial yaitu suhu, intensitas cahaya dan pH tanah.

Abstract

Wild flowering plants that are included in the understorey are plant communities that make up lower stratification near the surface of the ground. Effects of forest boundaries can be seen from gradual changes in microclimates and vegetation patterns from the edge of the forest to the forest. The impact of meeting these two different environmental conditions for plants and animals is called edge effect. Forest boundaries also have an impact on changes in environmental factors including temperature, humidity, light intensity, soil pH and canopy cover. These factors are thought to influence the diversity of wild flowering plants. The results of the study showed that there were 43 species of wild flowering plants in Bantarbolang Nature Reserve with a total of 978 individuals included in 22 families. The most common type is Piper caducibrachteum as many as 183 individuals. The edge effect has an effect on the diversity of wild flowering plants as evidenced by the increasing number of species obtained tends to be less. Wild flowering plants that have the highest index of importance are Piper betle (66.55%) followed Piper caducibrachteum (52.44%) and Ageratum conyzoides (46.17%). The most influential environmental factors in wild flowering plant diversity are light intensity. The intensity of the light getting deeper into the forest is lower because the sunlight entering the forest is blocked by tree canopies.

Abstract

An investigation on diversity monitoring of ginger family (Zingiberaceae) was carried out on Jengok, Banjaran, Kranji, and Pelus riverbanks in Purwokerto. This study required conventional surveys and repeated measurements to identify and to evaluate changes. Twelve permanent plots were established in 1990 covering the north, central, and south parts of the rivers. The ginger vegetation in 2005 was compared with data taken in 1990, 1997, and 2003. The result of this study showed that the number of spesies in most of the bank reached the peak in 2003 then decreased again in 2005.

Abstract

Klasifikasi adalah suatu proses yang dilakukan untuk menemukan sebuah model dengan tujuan untuk memperkirakan kelas dari suatu objek yang kelasnya tidak diketahui. Salah satu permasalahan yang dihadapi pada klasifikasi adalah tentang ketidakseimbangan kelas (imbalance Class) yang mana suatu dataset terdapat jumlah jumlah kelas yang datanya tidak merata Sehingga memberikan dampak yang tidak baik pada hasil klasifikasi. Cara mengatasi ketidakseimbangan kelas pada klasifikasi dengan menerapkan metode SMOTE (Synthetic Minority Over-sampling Technique). Pengujian data penyakit gagal jantung dengan penerapan metode metode SMOTE dapat meningkatkan permforma akurasi dari beberapa algoritma klasifikasi. Hasil kinerja yang diperoleh menunjukan bahwa model pengklasifikasi SMOTE Random Forest memiliki nilai accuracy yang lebih tinggi dibandingkan dengan beberapa model lainnya dengan nilai accuracy sebesar 0,881 atau 88,1% yang dan nilai AUC sebesar 0.947 atau 94,7%.

Abstract

Jambu semarang (Syzygium samarangense) terdiri dari banyak kultivar dengan kadar gula yang berbeda-beda. Pada setiap buah, kandungan gulanya tidak merata. Tingkat kemanisan buah seringkali menjadi penentu nilai ekonomi dari jambu semarang. Tujuan penelitian ini adalah 1) untuk mengetahui sebaran gula pada berbagai kultivar jambu semarang, 2) mengetahui sebaran kadar gula di dalam buahnya, 3) mengetahui pengaruh rerata hari hujan per bulan terhadap kandungan gula buah.  Metode yang digunakan dalam penelitian ini adalah survei dengan purposive sampling, observasi laboratorium dengan mengukur kadar gula dengan refraktometer, mengkorelasikan faktor lingkungan dengan kandungan gula buah. Hasil penelitian ini menunjukkan bahwa buah dengan kadar gula tertinggi terdapat pada kultivar Syzygium samarangense 'Sukaluyu' (maks 16,5 ◦Brix), S. samarangense 'Madu' (maks 14 ◦Brix), S. samarangense 'Kesuma Merah’ (max 10.5 ◦Brix), S. samarangense 'Citra' (maks 8.5◦Brix) yang cocok untuk buah-buahan segar. Sedangkan yang kadar gulanya rendah seperti S. samarangense 'Bajang Leang’ (4.5 ◦Brix), S. samarangense 'Kuning’ (4 ◦Brix) lebih cocok untuk lutis. Pada buah S. samarangense, gula tertinggi biasanya terakumulasi di bagian ujung buah, dan gula terendah berada di pangkal buah.  Kadar gula berkorelasi negatif dengan rerata hari hujan per bulan.  Makin sedikit hari hujan, buah semakin manis.

Abstract

Sodium hypochlorite (NaClO) was a chemical compound commonly used as a whitening and disinfectant agent. Kiara payung (Filicium decipiens), or the ferntree, was chosen as the object of research because easily obtained, has rapid growth, and thought to respond to alien substances' stress. The main purpose of this study was to find out the response of the ferntree plant, which is given stress from sodium hypochlorite. The research method used in this study was experimentation. The independent variable in this study was Sodium Hypochlorite Concentration (X), and the dependent variable was Sodium Hypochlorite Uptake Value (Y). Phytochemical analysis was performed using the argentometry and Atomic Absorption Spectrophotometry (AAS) techniques. Correlation analysis were performed using IBM SPSS 26. This study showed that the concentration of sodium hypochlorite has a positive effect on the uptake value of sodium hypochlorite. Limitations and suggestions to this study were to check the absorption based on soil level and examine other parts of the plant in the future study. In addition, another factors to the independent variables, such as genetics and variations in sodium hypochlorite concentration should be further explored, so that correlation analysis stands more optimal. Keywords: Ferntree, Root, Sodium Hypochlorite, Stress
