Abstract

ABSTRACTThe Effects of Recorded Predator Noise on Metabolism and Daily Activities of Rice-field RatThe use of poisonous rodenticides for controlling rice-field rat (Rattus argentiventer) in agricultural storehouses is the most common option, recently. This option was the easiest, the most effective and also efficient. In the other hand, the application of poisonous rodenticides causes various harmful risks. Rodenticides have potentialities for poisoning human, non-target animals, and other components of environment such as water and soil. The experiment aimed to explore the effects of recorded predator noise on metabolism and daily activities of rice-field rat. Results showed that the recorded of predator noise caused metabolic disorders that were indicated by the decrease of food and beverage intake by rice-field rat and the decrease of its body weight significantly, while the daily activities disorders were indicated by spending more time for locomotion and less time for foraging and resting. In conclusion, the treatments have an effect as repellent for rice-field rat.Keywords: Rice-field rat, Repellent, Pest, Metabolism, Daily activitiesABSTRAKPengendalian tikus sawah (Rattus argentiventer) di gudang-gudang tempat penyimpanan produk pertanian selama ini mengandalkan cara pengendalian kimiawi dengan menggunakan rodentisida. Salah satu potensi berbahaya dari cara pengendalian tersebut adalah sisa-sisa repihan rodentisida dapat pula mengontaminasi produk pertanian secara langsung, juga mengontaminasi lingkungan termasuk tanah dan air. Penelitian ini bertujuan untuk mengekplorasi pengaruh rekaman suara predator tikus yang diputar secara terus menerus dan berulang-ulang terhadap metabolime dan aktivitas harian tikus sawah di laboratioum yang selanjutnya dapat dimanfaatkan untuk pengedalian tikus sawah yang aman dan ramah lingkungan. Hasil penelitan menunjukkan bahwa tikus sawah yang diberi perlakuan suara predator mengalami gangguan metabolime yang ditandai dengan konsumsi makan dan minum, serta produksi feses dan sekresi urin yang berbeda dengan kontrol di kandang metabolisme. Tikus sawah yang diberi perlakuan suara predator juga mengalami gangguan pola aktivitas harian yang ditandai dengan jumlah waktu yang dihabiskan untuk locomotion (bergerak), foraging (makan dan minum) dan resting (terdiam dan tidur) yang berbeda dengan kontrol. Hasil ini menunjukkan bahwa suara predator memiliki potensi untuk diaplikasikan pada lokasi-lokasi tertentu, terutama gudang penyimpanan produk pertanian dengan tujuan untuk menolak dan mengusir serangan tikus sawah.Kata Kunci: Tikus sawah, Repelen, Hama, Metabolisme, Aktivitas harian

Abstract

Burung bondol jawa (Lonchura leucogastroides) merupakan salah satu hama pada tanaman padi ketika memasuki fase generatif. Petani seringkali menjaga sawah selama sehari penuh untuk mengendalikan hama burung. Cara tersebut kurang efektif karena banyak waktu petani yang terbuang hanya untuk mengendalikan burung. Penelitian ini bertujuan untuk mengetahui tingkat kematangan padi yang disukai bondol jawa dan mengetahui kelimpahan kunjungan tertinggi burung bondol jawa di sawah. Penelitian dilakukan pada bulan Maret hingga bulan Mei 2020 bertempat di lahan sawah milik petani di Desa Cileles, Jatinangor dan Laboratorium Vertebrata, Fakultas Pertanian, Universitas Padjadjaran. Metode uji kelimpahan kunjungan tertinggi dilakukan dengan menghitung jumlah burung yang berkunjung pada lahan penelitian. Sementara itu, metode uji preferensi pada bondol jawa dilakukan dengan membandingkan bagaimana cara makan bondol jawa ketika diberi pakan padi yang matang susu dan padi yang sudah matang penuh. Hasil penelitian menunjukkan bahwa bondol jawa menyerang sepanjang pengamatan, yaitu 11 MST-14 MST. Tingkat kematangan padi yang disukai bondol jawa adalah saat matang susu. Kelimpahan bondol jawa mengunjungi sawah adalah saat sore hari, yaitu mulai dari jam 14.00 hingga jam 17.00. Hal ini menunjukkan bahwa masa tersebut dapat digunakan petani untuk mengendalikan hama burung di sawah.

Abstract

The use of Bacillus amyloliquefaciens based fungicide has increased along with the modernization of agriculture. On the other hand, freshwater culture is generally juxtaposed with agricultural land. This study was conducted to determine the fungicide's sublethal effect on the survival and haematologist of common carp and tilapia as non-target organisms. The method used was a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used are: (A) control (0 ppm fungicide), (B) 0.5 ppm fungicide, (C) 1 ppm fungicide, and (D) 10 ppm fungicide. Observation time is 96 hours. Survival, white blood cells, and red blood cells are analyzed using analysis of variance, while the feed response, shock response, and water quality are analyzed descriptively. The results showed that 10 ppm fungicide was not lethal to common carp and tilapia with a survival rate of almost 100%. During 96 hours of fungicide exposure, the average white blood cell (WBC) of common carp increased from 8.84-10.46 x 104 cells/mm3 to 9.56-11.48 x 104 cells/mm3. Meanwhile, the mean WBC of tilapia increased from 11.36-19.44 x 104 cells/mm3 to 20.52-37.38 x 104 cells/mm3. The average red blood cell (RBC) of common carp decreased from 6.60-7.01 x 106 cells/mm3 to 6.06-6.76 x 106 cells/mm3. Meanwhile, the mean RBC of tilapia decreased from 5.26-7.55 x 106 cells/mm3 to 2.21-3.76 x 106 cells/mm3. The results showed that the feed response did not change during the study, but the shock response decreased at 96 hours. Water quality during the study was still in the optimal range for common carp and tilapia culture. Key words : Bacillus amyloliquefaciens, fungicide, sublethal effect, common carp, tilapia

Abstract

The chrysanthemum plant (Chrysanthemum morifolium Ramat.) contains many secondary metabolites such as flavonoids and various volatile compounds that can be utilized as drugs. Tissue culture can be an alternative to enhance the production of certain secondary metabolite. The study aimed to determine the types of secondary metabolites that contained in shoot culture, callus and field plants of C. morifolium. The research method was exploration in the laboratory to analyze and compare the content of secondary metabolite from shoot culture, callus and field plants of C. morifolium. Callus was induced by explants of C. morifolium plantlet stems and leaves respectively on MS medium with an addition of 3 ppm 2,4-D + 2 ppm kinetin and 4 ppm 2,4-D. For shoot culture, single nodule explants with one leaf were planted on MS media with the addition of 1 ppm BAP. The secondary metabolite compouds were analized and identified by GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that various types of secondary metabolites contained in shoot culture, callus and field plants of C. morifolium. In callus culture from leaf explants, four compounds from groups of alcohol, acetic acid and organosilicon were identified, whereas in callus culture from stem explants were identified eight compounds from aldehydes, esters, alkanes, and carboxylic acids group. In the shoot culture, nine compounds of alcohol, ketone, aldehyde, cycloalkane and organosilicon group were identified, while in the field plants five compounds were identified from the cycloalkanes, ketones, organoborones and organosilicon group. Some detected compounds have a potential as precursors of alkaloid, phenolic, and flavonoid.Keywords: chrysanthemum, culture, shoots, callus, secondary metabolites.

Abstract

Pemahaman petani yang rendah tentang konservasi tanah dan air akan membuat lahan pertanian rentan terhadap erosi yang pada akhirnya menurunkan produktivitas lahan pertanian. Tujuan kegiatan tersebut adalah untuk memberikan pemahaman kepada para petani di daerah tersebut tentang pentingnya penerapan konservasi tanah dan air. Kegiatan pengabdian kepada masyarakat berupa penyuluhan dengan pentingnya pemahaman konservasi tanah dan air bagi petani di Desa Karyajaya dan Panembong, Kecamatan Bayongbong, Kabupaten Garut. Berdasarkan hasil data kuesioner yang dikumpulkan, dapat disimpulkan bahwa pada awalnya peserta penyuluhan memiliki pengetahuan yang minim tentang wawasan konservasi tanah dan air, khususnya dampak erosi dan metode yang bisa digunakan dalam menurunkan terjadinya erosi. Setelah dilakukan penyuluh­an, terlihat peningkatan wawasan serta keinginan petani untuk menjaga lingkungan pertanian agar terhindar dari dampak erosi.

Abstract

Imidacloprid is a synthetic chemical compound used as an insecticide product. Despite the benefits that insecticides provided in controlling plant pests and increasing crop yields, the use of insecticides was associated with side effects in humans The purpose of this study was to evaluate the active ingredient of imidacloprid 200 g/l in an insecticide formulation to ensure the safety of the pesticide for the applicator. This study was conducted based on appropriate toxicological tests and assessment based on pre-clinical tests in the form of evaluation of irritation and sensitization. The method used was descriptive quantitative based on the OECD 404, 405, and 406 guidelines for albino New Zealand rabbits and adult Dunkin Hartley albino guinea pigs. The results showed that the imidacloprid compound did not cause irritation symptoms in the eyes (cornea, iris, conjunctiva, and chemosis) and skin (erythema and edema) with a score of zero (0). In addition, the results of the sensitization test at a concentration of 12.5 - 100% did not show the formation of erythema which was indicated by a score of zero (0). In conclusion, imidacloprid 200 g/l did not caused irritation and sensitivity reactions in test animals so this compound is safe to use as an insecticide.

Abstract

Whiteflies Aleurodicus dispersus and Bemisia tabaci are major pest on several horticultural crops because of their feeding activity which absorbs fluids through the phloem. They are also Geminivirus vectors. Whiteflies reduce yield crop around 30%-100% on high attack. Whiteflies have morphological variety that affect feeding and reproduction behaviour in certain host plant. Identification was carried out on the puparium shape because of phenotype variations depend on the physical character of the leaf surface. This research aimed to study differences the morphology of whiteflies puparium in several plants and to create an identification key in PDF format. This research used the literature study method from textbooks and published national and international journal. The samples were taken from Bandung Regency and West Bandung Regency, West Java on tomatoes, chayote, peanuts, and beans. Then puparium was prepared in a microscope slides-mounted and morphological identification was carried out. The result obtained are subdorsum of A. dispersus has compound pores and thorax without tracheal comb. Lingula is very long, usually extending past the vasiform orifice and has two pairs of setae at the end. While the puparium of B. tabaci has lobe-shaped lingula and usually short not extending past vasiform orifice. Puparium has caudal furrow and a pair of caudal setae at the end. Subdorsum without compound pores and submarginal row of papillae absent. The result of puparium observation was photographed and used for making identification key in PDF format. Other literature study on the biological character and the whiteflies control technique are carried out to support comprehensive information for making the identification key. This identification key in PDF format can be used as a tool to identify A. dispersus and B. tabaci.
