Abstract

Abstrak Pupuk dan pestisida kimiawi merupakan hal penting pada sistem budidaya tetapi jika  penggunaannya berlebih dapat meningkatkan kandungan logam berat kadmium  (Cd) dalam tanah. Penelitian ini bertujuan menganalisis pertumbuhan tanaman kentang (Solanum  tuberosum L.) pada tanah yang terakumulasi logam berat kadmium. Sampel tanaman berasal dari lokasi pertanian kentang Pangalengan Jawa Barat. Parameter yang diukur yaitu kandungan klorofil, biomassa, kandungan logam kadmium dalam tanah dan umbi kentang. Kandungan kadmium dalam sampel tanah dan umbi kentang diukur dengan menggunakan Atomic Absorption Spectrophotometry (AAS). Hasil penelitian menunjukkan kandungan kadmiumpada lahan pertanian kentang telah melebihi ambang batas. Kadmium terakumulasi dalam umbi kentang, tetapi masih berada di bawah ambang batas. Klorofil, berat kering, dan berat basah mengalami kenaikan setiap minggunya (4-10 Minggu Setelah Tanam). Adanya logam kadmium  yang diserap oleh tanaman kentang dapat menghambat pembentukan  klorofil sehingga akan mempengaruhi biomassa tanaman. Kata kunci: klorofil, biomassa, kentang, kadmium Abstract Chemical fertilizers and pesticides are important in the culture system but if the excessive usage may increase the content of heavy metals cadmium ( Cd ) in the soil. This study aims to analyze the growth of the potato ( Solanum tuberosum L.) on the ground that accumulate heavy metals cadmium. Plant samples derived from potato farming locations Pangalengan West Java.The parameters are chlorophyll content, biomass, cadmium  content in soil and potato tubers. The content of cadmium in soil and potato tuber samples were measured using Atomic Absorption Spectrophotometry (AAS). The results showed cadmium content in potato farms has exceeded the threshold. Cadmium accumulates in potato tubers, but still below the threshold. Chlorophyll, dry and fresh weight increase every week (4-10 Weeks After Planting). The presence of the metal cadmium is absorbed by the potato can inhibit the formation of chlorophyll that will affect plant biomass . Keywords: chlorophyll, biomass, potatoes, cadmium

Abstract

Abstrak Penelitian telah dilakukan untuk mengkaji kandungan air daun sebagai salah satu respon fisiologi  pada tanaman padi lokal Sulawesi Utara (Superwin, Ombong, Temo dan Burungan) pada fase vegetatif saat mengalami perlakuan rendaman dan kekurangan air. Tanaman tidak disiram dengan air selama 14 hari pada perlakuan kekurangan air. Tanaman dalam pot dimasukkan ke dalam bak air yang berisi air dengan tinggi rendaman 15 cm di atas permukaan media selama 14 hari pada perlakuan rendaman. Kandungan air daun berbeda antar varietas dan antar perlakuan, tetapi interaksi antara faktor varietas dan faktor  perlakuan cekaman tidak menyebabkan perbedaan kandungan air daun yang nyata. Kandungan air daun terendah diamati pada varietas Superwin (0,78 mg/L), sedangkan kandungan air daun yang tertinggi diamati pada varietas Ombong (0,89 mg/L). Kandungan air daun pada keempat varietas padi berturut-turut dari yang terendah ke yang tertinggi adalah pada perlakuan kekurangan air (0,79 mg/L), kontrol (0,84 mg/L) dan rendaman (0,90 mg/L). Kata kunci: kandungan air daun, kekurangan air, padi lokal Sulut, rendaman, vegetatif AbstractA study was carried out to evaluate leaf water content as one of the physiological responses in the North Sulawesi Utara local rice (Superwin, Ombong, Temo and Burungan) at the vegetative phase under waterlogging and water deficit condition. When treatments commenced, water was withheld from water-deficit plants and the water level was 15cm above the waterlogged plants. Leaf water content was different among varieties and among treatments, but the interaction between varieties and treatments did not result in significantly different leaf water content. The smallest leaf water content was observed in Superwin (0.78 mg/L), whereas the largest leaf water content was in Ombong (0.89 mg/L). Leaf water content in these four rice varieties from the lowest to the highest was in the treatments of water deficit (0.79 mg/L), well-watered (0.84 mg/L) and waterlogging (0.90 mg/L), respectively.Keywords: leaf water content, North Sulawesi Utara local rice, water deficit, waterlogging, vegetative

Abstract

AbstrakPenelitian tentang perubahan morfologi dan anatomi kalus Catharanthus roseus dengan pemberian perlakuan triptofan telah dilakukan. Penelitian ini bertujuan untuk melengkapi informasi tentang perubahan yang terjadi pada kalus khususnya struktur anatomi dan morfologi sel kalus Catharanthus roseus setelah diberi perlakuan prekursor triptofan 175 mg/L. Pengamatan anatomi kalus dilakukan dengan metoda Parafin yang didokumentasikan dengan mikroskop Nikon Halogen 100 W perbesaran 10X10 dan difoto dengan camera Nikon DXM 1200F. Penampakan morfologi kalus didokumentasikan dengan camera digital Cannon. Hasil penelitian menunjukkan bahwa pertumbuhan kalus yang diberi perlakuan triptofan lebih lambat pada awalnya, namun bertahan hidup sampai 40 hari kultur. Kalus tanpa triptofan cepat bertumbuh pada awalnya sampai hari ke 18 kultur, setelah itu tidak ada pertumbuhan lagi. Setelah kultur 40 hari kultur, kalus dengan perlakuan triptofan tetap bertumbuh dengan baik sedangkan kontrol sudah rusak atau lisis. Struktur sel kalus perlakuan triptofan setelah 28 kali subkultur menunjukkan adanya penebalan dinding sel, sedangkan sel kalus kontrol mengalami lisis atau kerusakan sel.Kata kunci: anatomi, Catharanthus roseus, kalus, morfologi, triptofanAbstractA research on the morphological and anatomical changes on tryptophan-treated callus of Catharanthus roseus was conducted. This study aimed to complete the information about the changes, particularly on anatomical and morphological structure of Catharanthus roseus callus cells after treatment of 175 mg/L precursor tryptophan. Anatomical observations was conducted using paraffin method, documented using a Nikon microscope with a 10x10 magnification and the photograph was taken using the Nikon DXM 100 W Halogen 1200F camera. The appearance of callus morphology was documented by Cannon digital camera. The results showed that the growth of tryptophan-treated callus was slower at the beginning, but it survived by 40-day culture. Non-tryptophan callus grew rapidly by 18-day culture and did not grow later on. Tryptophan-treated callus for 40 days grew well, whereas control callus was damaged or lysis. The tryptophan-treated callus after 28 times subcultures showed cell wall thickening, whereas the control callus cells are lysis or damaged.Keywords: anatomy, callus, Catharanthus roseus, morphology, tryptophan

Penelitian ini bertujuan menganalisis kehadiran logam-logam berat timbal (Pb), kadmium (Cd), tembaga (Cu) dan seng (Zn) di air dan sedimen Sungai Lowatag. Penelitian ini menggunakan metode purposive sampling pada tiga stasiun yang tersebar dari hulu ke hilir. Pengambilan sampel sedimen dilakukan secara komposit di tiap stasiun. Sampel air diulang sebanyak tiga kali di tiap stasiun. Kehadiran logam berat-logam  berat  pada sedimen dengan konsentrasi berbeda-beda yaitu Cu berturut-turut dari Stasiun I, II dan III yaitu 13; 17 dan 13 mg/kg dan Zn yaitu 73; 48 dan 56 mg/kg. Kehadiran logam berat Pb di sedimen dari Stasiun I, II dan III yaitu 28; 19,1 dan 28,2 mg/kg masih di bawah Nilai Ambang Batas (NAB) menurut RNO/1981 sebesar 10 mg/kg – 70 mg/kg. Kehadiran logam berat Cd berturut-turut 3,83;  2,69 dan 4,03 mg/kg telah melampaui NAB menurut RNO/1981 (0,1 mg/kg – 2,0 mg/kg).

ABSTRAKBurung merupakan salah satu fauna yang memiliki keanekaragaman hayati yang cukup tinggi di Indonesia dengan jumlah 1598 jenis burung, di antaranya terdapat burung pemangsa. Elang jawa (Nisaetus bartelsi) yang merupakan burung endemik di Pulau Jawa. Taman Nasional Gunung Halimun Salak (TNGHS) merupakan habitat bagi elang Jawa, hal ini dikarenakan kondisinya yang masih cukup baik. Penelitian ini bertujuan untuk mempelajari dan menganalisis aktivitas harian elang Jawa serta faktor yang mempengaruhi aktivitas elang jawa di TNGHS. Metode yang digunakan yaitu survei dan pemantauan sarang, pengamatan aktivitas harian, pengumpulan dan analisis data.

This observation aims to study and find out the daily activities of the Javanese eagle and the factors that influence the activity of the Javan Hawk Eagle in HSNP. The methods used are nest surveying and monitoring, observing daily activities, collecting and analyzing data. Based on observations by Nisaetus bartelsi in HSNP, it was found that the Javan Hawk eagle's daily activity was perched with a percentage of 66%, and flew 34% with the highest frequency of activity at 10:00 to 14:00.
