Abstract

Meloidogyne spp. merupakan nematoda parasit yang dapat menurunkan produktivitas tomat. Pemanfaatan seluruh bagian tanaman Tagetes patula L. dalam bentuk serbuk sebagai nematisida nabati dapat menjadi salah satu alternatif pengendalian nematoda ramah lingkungan. Tujuan penelitian untuk mengetahui pengaruh dan dosis serbuk T. patula yang efektif dalam menekan serangan nematoda bengkak akar (Meloidogyne spp.) pada tanaman tomat. Penelitian dilaksanakan pada bulan Maret sampai Juni 2021 di Laboratorium Fitopatologi, Divisi Laboratorium Nematologi dan Rumah Kaca Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Padjadjaran, Jatinangor. Penelitian menggunakan metode percobaan dengan Rancangan Acak Kelompok (RAK) yang terdiri atas 6 perlakuan dan 4 ulangan. Perlakuan terdiri atas kontrol (tanpa serbuk T. patula), serbuk T. patula sebanyak 10, 20, 30, 40 g per 2 kg tanah dan karbofuran 2 g per 2 kg tanah. Hasil penelitian menunjukkan bahwa aplikasi serbuk T. patula berpengaruh dalam menekan serangan Meloidogyne spp. pada tanaman tomat. Serbuk T. patula berpotensi menurunkan jumlah juvenil II Meloidogyne spp. dalam 100 ml tanah dan cenderung menurunkan jumlah gall. Aplikasi serbuk T. patula 40 g/2 kg tanah mengakibatkan jumlah gall terendah (32,25 gall) dengan penekanan 41,36%, dan jumlah juvenil II Meloidogyne spp. dalam 100 ml tanah terendah (12,30 ekor) dengan penekanan 51,49% yang menunjukkan setara dengan aplikasi karbofuran 2 g/2 kg tanah.

Abstract

Tanaman beracun oleander (Nerium oleander) memiliki potensi untuk mengendalikan hama utama tanaman jagung, salah satunya ulat grayak jagung (Spodopetera frugiperda). Namun demikian, studi ekstrak daun N. oleander yang disiapkan dengan menggunakan pelarut yang berbeda belum diketahui efektivitasnya dalam mengendalikan S. frugiperda. Penelitian ini bertujuan untuk mengetahui perbedaan berbagai pelarut ekstrak daun N. oleander terhadap terhadap mortalitas, konsumsi makan, dan kelulushidupan larva S. frugiperda. Penelitian melibatkan ekstraksi daun N. oleander berdasarkan perbedaan polaritas pelarut (n-hexane, etanol, metanol, air) untuk lima konsentrasi uji yang berbeda serta perlakuan kontrol yang diulang empat kali menggunakan Rancangan Acak Lengkap (RAL) pada larva S. frugiperda instar III. Hasil penelitian menunjukkan bahwa ekstrak kasar metanol daun N. oleander memberikan pengaruh penghambatan konsumsi pakan larva S. frugiperda sebesar 0,071 ± 0,028 g dibandingkan kontrol 0,642 ± 0,031 g. Selain itu, ekstrak kasar metanol daun N. oleander menunjukkan persentase mortalitas tertinggi sebesar 97,5 ± 0,50%, diikuti oleh ekstrak kasar air 70 ± 0,82%, ekstrak kasar etanol 57,50 ± 0,96%, dan ekstrak kasar n-hexane 50,00 ± 0,82%. Kelulushidupan larva, pupa, dan imago S. frugiperda menunjukkan nilai persentase terendah sebesar 2-3,4% ketika diaplikasikan ekstrak kasar metanol daun N. oleander. Secara keseluruhan, metanol adalah pelarut yang paling baik untuk mengekstrak daun N. oleander terhadap mortalitas, daya konsumsi, dan kelulushidupan larva S. frugiperda.

Abstract

Munia birds (Lonchura spp.) are pests that attack paddy plants during the reproductive phase. The traditional methods of controlling birds are considered less effective because birds can adapt to the tools used. This study aimed to determine the effectiveness of a metallic light-based bird-repellent prototype to reduce paddy yield loss. The experiment was conducted in Cileles Village paddy fields, Jatinangor Subdistrict, Sumedang Regency, West Java Province, Indonesia. The effectivity of the prototype was tested by measuring the effective distance (m2), counting the frequency of bird visits (number of visits), bird populations, and the level of paddy damage (%), and paddy yield (kg/64 m2). The result of the experiment showed that 3 m was an effectual deterrent factor for the prototype, thus the tool can protect paddy plants with an area of 28.26 m2. The frequency of bird arrivals in the treatment was 22.25 times, compared to 61.25 times in the control; the bird population in the treatment was 48.25 birds, while the control was 108.75 birds; the level of damage to paddy panicles in the treatment was 10.11%, compared to 37.79% in the control; and the production of paddy yield with the repellent was higher (33.37 kg/64 m2) than the control (23.09 kg/64 m2). This innovative prototype was potentially able to deter bird pests in the paddy fields.

Abstract

Banana (Musa spp.) is one of the agricultural commodities that’s widely cultivated and used by the local community. Currently, only 101 types of local varieties of bananas are registered in Indonesia; one of them is the Roid banana from Jatigede District. Roid bananas grow wild without any mandatory special care. Continuous use without any conservation and preservation efforts can lead to scarcity of Roid banana germplasm as a genetic resource. Therefore, it is necessary to identify the distribution and diversity of Roid bananas through in situ exploration and characterization activities. This study aimed to identify the potential for genetic diversity and develop conservation efforts for the local variety of Roid banana (Musa spp.) in Jatigede District. This research was conducted from November 2021 - March 2022 in three villages in Jatigede District: Ciranggem Village, Jemah Village, and Mekarasih Village. The research used exploratory, survey, and interview methods as data collection techniques. Based on the results of the study, Jatigede District has a wide genetic diversity and distant kinship among Roid banana accessions. Characters that contributed to genetic diversity among accessions were the width of the midrib margin, the diameter of the bunch, and the length of the pseudostem. MS1.3 was the selected accession with its potential characteristics: more combs in bunches, leaf width of 71-80 cm, leaf length of 171-220 cm, and the number of rhizomes > 5 tillers.

Abstract

The fall armyworm (FAW), Spodoptera frugiperda, is one of the major pests of maize, exhibiting high adaptability and causing significant losses to agriculture in Indonesia. An environmentally friendly approach to controlling FAW infestations involves using local toxic plants, such as Cerbera odollam, also known as Bintaro, which contains cardenolide glycosides, saponins, and alkaloids with potential as botanical insecticides. This study aimed to evaluate the effect of the methanol extract of C. odollam leaves on the locomotion and exploration activities of FAW larvae. The test was conducted using the leaf dip method at concentrations of 0, 1000, 2000, and 4000 ppm, with six replications. The samples were then analyzed and observed using the Organism Video Tracking Application ToxTrac v2.96. Results showed that higher extract concentrations led to a decrease in larval speed, from 17.48 mm/s to 1.83 mm/s, and a reduction in exploration area, from 48 to 9. In addition, larval immobility duration (freeze activity) increased nearly sevenfold compared to the control. These findings indicate that C. odollam shows promise as a natural insecticide that repels FAW larvae by limiting their movement and exploratory behavior.

Abstract

Insecticides can be used to overcome pest attacks in agricultural and plantation sectors. The botanical insecticide is more widely used because more friendly to the environment than chemical insecticides. Neem is one of the plants that can be used as basic ingredient for botanical insecticides because it contains the compound azadirachtin. Insecticide enter the cultivation area because carried by flowing water. Tilapia is a fish that can be used as a bioindicator of pollution levels, water quality, and changes in the aquatic environment. This study aims to determine the effect of exposure insecticide with azadirachtin active ingredient on growth and survival rate of tilapia. This research was conducted in March and August for the preliminary test and September-October 2022 for the main test at Ciparanje Inland Aquaculture Hatchery, Padjadjaran University. The fish used in this study averaged 6,70 ± 0,014 cm. This study used experimental method, Completely Randomized Design with five treatments and three replications. The treatments used were exposure to insecticides with different doses, namely A(0 ppm), B(26.25 ppm), C(52.5 ppm), D(78.75 ppm), E(105 ppm). Parameters observed included absolute length growth and weight growth, survival rate, and water quality until 28th day. Growth and survival data analyzed using the F test and continued with Duncan's test at the 95% level of confidence. The results showed that exposure insecticide can inhibited growth and affected the survival of tilapia. Treatment C(52.5 ppm) is a safe concentration for the survival of tilapia and the highest growth is the treatment without addition of insecticide.

Abstract

This research aims to examine the effect of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin on the survival and growth of common carp (Cyprinus carpio). The study was conducted from September to October 2022 at the Ciparanje Inland Fisheries Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used was an experimental method, and the experimental design employed was a completely randomized design (CRD). The study included six treatments with three replications. The test fish used were Majalaya strain common carp fingerling, measuring 7-8 cm, obtained from the Cibiru Fish Seed Center in Bandung City. The treatments examined in this study were Treatment A (0 ppm), B (12.8 ppm), C (25.6 ppm), D (38.4 ppm), E (51.2 ppm), and F (64 ppm). The insecticides were administered once at the beginning of the research in the water, which served as the maintenance medium, according to the treatment concentrations. The parameters observed were survival rate, growth, and water quality. Observations were conducted for 28 days after the application of the plant-based insecticides. The highest percentage of survival was found in Treatment A (control) at 100%, while the lowest percentage of survival was observed in Treatment F (64 ppm) at 81.7%. The highest absolute length growth was recorded in Treatment A (control) at 2.73 cm, and the lowest absolute length growth was observed in Treatment F (64 ppm) at 1.97 cm. The highest weight growth was observed in Treatment A (control) at 4.2 g, and the lowest absolute weight growth was found in Treatment F (64 ppm) at 2.6 g. The research indicates that the growth and survival of common carp fingerling (Cyprinus carpio) decrease due to the influence of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin.
