Abstract

Mount Gede Pangrango National Park (TNGGP) is a nature reserve area divided into seven zoning areas located in West Java province. In this location, there is a place that is lush and humid, so that this location can be a good habitat for herpetofauna, especially the anura group. The purpose of this research was to identify and determine the morphology and morphometric of amphibians in the order Anura. It is hoped that this information can be used to help inventory and improve its conservation. The research method used was descriptive explorative and Visual Encounter Surveys (VES). The research results obtained three species of frogs from the order Anura, namely Megophrys montana, Hylarana chalconota, and Limnonectes microdiscus. These species of frogs have morphology and morphometric that indicate these species have entered their juvenile or adult period. In the three species of frogs found, two species of frogs entered adult phase and one species of frog in juvenile phase.

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan Klorofil-a dan kualitas air terhadap budidaya tiram yang ada di waduk Alue Naga, Banda Aceh. Penelitian ini menggunakan metode survey dengan melihat langsung kondisi perairan di lokasi penelitian dan pengambilan sampel menggunakan metode purposive sampling. Pada penelitian ini pengambilan sampel air dilakukan sebanyak 1 kali pada 3 stasiun dengan melakukan 3 kali pengulangan. Setiap stasiun merupakan tempat yang berbeda, stasiun 1 di aliran air yang merupakan tempat air masuk dan menerima buangan limbah. Stasiun 2 berada di tengah waduk dan stasiun ke-3 yang berada di pintu keluar air pada waduk. Hasil pengukuran konsentrasi klorofil-a yang di peroleh diperairan waduk Alue Naga berbeda di setiap stasiun nya dengan kisaran 2,772 µg/l - 6,956 µg/l dengan nilai rata-rata keseluruhan 6,692 µg/l. Kandungan klorofil-a yang berada di waduk tersebut cenderung lebih tinggi pada stasiun 1 yang merupakan tempat masuk nya air (inlet) dan cenderung lebih rendah pada area transisi yang merupakan area dengan kecepatan arus yang mulai menurun.Kata kunci : Budidaya, Tiram, Klorofil

Abstract

Bayam merupakan tanaman sayuran yang memiliki kandungan kalsium oksalat di daunnya. Salah satu peran kalsium oksalat dalam tanaman adalah toleransi pada kekeringan. Penelitian ini penting dilakukan untuk mengetahui pengaruh kekeringan terhadap pertumbuhan dan kandungan kalsium oksalat daun bayam. Sehingga, tujuan penelitian ini adalah mengetahui pengaruh kekeringan terhadap pertumbuhan dan kandungan kalsium oksalat daun bayam varietas Giti Hijau. Metode penelitian menggunakan rancangan acak kelompok dengan perlakuan disiram setiap hari dan disiram ketika layu 50%. Disiram setiap hari pada waktu pagi dan sore dan disiram ketika layu 50% pada populasi tanaman yang mengalami kelayuan 50%, yaitu 48 tanaman. Dilakukan sebanyak 12 ulangan per perlakuan. Setiap ulangan terdiri dari 4 unit percobaan, sehingga total 192 unit percobaan. Setiap unit percobaan terdapat 3 tanaman dengan 1 tanaman diamati dan 2 tanaman yang tidak diamati akan dipotong. Tanaman yang diamati memiliki tinggi tanaman yang sama. Diamati berat basah, berat kering, tinggi tanaman, jumlah daun, luas daun, panjang akar, dan kandungan kalsium oksalat selama sebulan. Data dianalisis secara statistika dengan uji T tidak berpasangan. Jumlah daun dan jumlah daun cabang dianalisis dengan khi kuadrat. Hasil penelitian menunjukkan kekeringan hanya mempengaruhi pertumbuhan bayam varietas Giti Hijau dan tidak mempengaruhi kandungan kalsium oksalat. Pengaruh kekeringan terhadap varietas Giti Hijau menghasilkan respon tinggi tanaman, jumlah daun, luas daun, dan panjang akar lebih tinggi dibandingkan penyiraman setiap hari, kecuali berat basah yang mengalami penurunan. Sementara itu, berat kering tidak terdapat pengaruh yang signifikan.

Abstract

Oil is used as an important component in human life as an energy source. The fried oil gives a delicious taste for consumption. However, the remaining cooking oil that has been cooked is discarded in the surrounding environment which is the cause of soil contamination by the oil. Thus, bioremediation is carried out to degrade contaminants with the ability of microorganisms or macroorganisms to become harmless compounds. The purpose of this research was to isolate and characterize the morphology of bacteria hydrocarbon-degrading from the environment or soil that had used cooking oil spills. The research method used was purposive sampling and descriptive qualitative. Purposive sampling is by determining where the sample to be taken has soil contaminated with used cooking oil and qualitative description is by describing the morphological characterization of the bacterial degrading isolates from the sample. The results of the research obtained that two bacterial isolates had a round shape, optically opaque, and flat edges. BCO-1 isolate has a brown color with a flat elevation and BCO-2 is white with a convex elevation. The bacteria degrading in BCO-1 isolates had a significant ability to degrade used cooking oil that was contaminated in the soil compared to BCO-2 isolates based on changes in the level of oil fluid.

Abstract

Amaranth is a plant that has calcium oxalate content in leaves. One of the roles calcium oxalate in plants is to increase drought tolerance. In addition, amaranth leaves also have anomocytic stomata. Stomata plant leaves are known to be formed genetically and not affected morphoanatomically under drought stress conditions, except density and conductance. Therefore, the research aimed to find out how the response of calcium oxalate levels and stomata of amaranth leaves (Amaranthus tricolor var. Red Giti) under drought stress. The research method used was a randomized block design (RBD) with two treatments, which are watering every day (WD) and watering at 50% wilting (SD) by observing stomatal density (stomata/mm2) and calcium oxalate content (%). Data were analyzed statistically with independent T-test and chi-square. The results showed that stomatal density and calcium oxalate content were affected by drought stress with a significantly decreased response. This indicates that the amaranth plant may become a plant that is resistant to drought stress by decreasing stomatal density and calcium oxalate levels.
