Abstract

The rice brown planthoper, Nilaparvata lugens Stal (Homoptera: Delphacidae), is one of  key pests on rice. The use of insecticides unwisely has caused N. lugens to develop resistance. The objective of this research was to determine the potency of N. lugens to develop resistance through laboratory, selections to fipronil, a relatively new insecticide.  A population of N. lugens was collected from rice field in Muntilan, Central Java during the outbreak in 2001. Selections were carried out every generation for four generations against third instars. Selection was started by dipping Cisadane rice seedlings in a solution of fipronil (50 ppm). The concentration was increased every generation, and the concentration used for the last selection (the fourth generation) was 250 ppm. To determine the rate of resistance development, biassays were carried out to estimate LC50 of fipronil against selected and non-selected populations of N. lugens, and their LC50 values were compared to that of the laboratory population. The laboratory population has been in the laboratory for 15 years without any insecticides exposure. The founding population was as susceptible as the laboratory population to fipronil because their LC50 values were similar. Even though the concentration for selections was increased from generation to generation, the survival rate of N. lugens increased steadily. After four generations of selection, the resistance of selected population was 27.3 times than the non-selected population. These findings indicate that N. lugens population has the potency to develop resistance to fipronil in a continuous selection pressure is applied.

Abstract

Mikroba agens hayati dari perakaran tanaman berpotensi untuk dimanfaatkan sebagai Biopestisida, baik sebagai biofungisida maupun bioinsektisida.  Tujuan kegiatan ini adalah memberikan pelatihan kepada kelompok tani Rukun Bersama di Kota Palangka Raya agar mampu membuat biopestisida secara mudah dan murah untuk mengendalikan hama dan penyakit yang ramah lingkungan. Biopestisida merupakan alternatif mengurangi penggunaan pestisida kimia, sehingga dapat menghemat biaya usaha tani di masa Pandemi Covid 19. Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilaksanakan pada bulan Agustus hingga September 2021 pada Kelompok Tani Rukun Bersama yang berlokasi di Kelurahan Tanjung Pinang, Kota Palangka Raya, Kalimantan Tengah. Metode pengabdian masyarakat dengan cara diskusi interaktif, pelatihan secara langsung teknik isolasi agens hayati menggunakan umpan nasi dan umpan serangga larva ulat hongkong (Tenebrio molitor), pembuatan biopestisida formulasi padat dan formulasi cair. Hasil evaluasi menunjukkan bahwa 100% petani pengetahuannya meningkat terhadap mikroba agens hayati yang bermanfaat sebagai bahan pembuatan Biopestisida, seperti jamur Trichoderma sp., Beauveria sp. dan Metarhizium sp. yang diisolasi dari perakaran tanaman bambu, serai, sirih, pisang, cabai dan putri malu.  Petani secara mandiri mampu membuat biopestisida formulasi padat dan cair, dengan tingkat kontaminasi pada substrat hanya sekitar 5 %, hal ini menunjukkan bahwa petani terampil melakukan proses isolasi dan perbanyakan subtrat dengan tingkat keberhasilan hingga 95%. Microbial biological agents from the root zone of plants have the potential to be used as biopesticides, both as bio fungicides and bioinsecticides. The purpose of the current activity is to make biopesticides easy and feasibly to control pests and diseases that are also environmentally friendly. Biopesticides are an alternative to reduce the use of chemical pesticides and save farming costs during the Covid-19 Pandemic. This Community Service activity was carried out from August to September 2021 at the Rukun Bersama Farmer Group in Tanjung Pinang Village, Palangka Raya city, Central Kalimantan province. Community service methods included interactive discussions, hands-on training on biological agent isolation techniques using rice bait and insect bait for Hong Kong caterpillar larvae (Tenebrio molitor), and the production of solid formulations and liquid formulations of biopesticides. The results of the evaluation showed that 100% of farmers' knowledge was increased about microbial biological agents that were useful as ingredients for making biopesticides, such as Trichoderma sp., Beauveria sp. and Metarhizium sp. isolated from the roots of bamboo, lemongrass, sirih (Piper betle), banana, chili and putri malu (Mimosa pudica). Farmers independently made solid and liquid biopesticide formulations with a substrate contamination level of about 5%. It showed that farmers were skilled in the process of isolation and substrate propagation with a success rate of up to 95%.

Abstract

Lebak swamp weeds such as Kayambang (Salvinia molesta) grow abundantly. They can be used as compost, which effectively improves soil fertility, increasing nutrients N, P, and P K quickly and environmentally friendly. The effectiveness of compost fertilizer needs to be increased by adding indigenous microbes as decomposers and biological agents to control plant diseases. The activities carried out to empower horticultural farmer groups on sandy land in Tanjung Pinang Village, Palangka Raya are through socialization, training in composting with three types of antagonist fungus Trichoderma sp. (Trichocompost), facilitate the procurement of weed chopping machines, assist farmers in horticultural crop cultivation, and increase farmers' independence in self-supporting organic fertilizers. The use of Kayambang as Trichocompost with microbial decomposers and indigenous biological agents is new knowledge for partner farmers. The application of Trichocompost on the demonstration plots shows that eggplant plant growth and yields are excellent, meaning that Trichocompost can improve the fertility of sandy soils. Farmers participating in the training stated that the use of Trichocompost could reduce farming costs because it can substitute for manure that has been used by farmers and can meet the self-help needs of organic fertilizers. Participants wanted an advanced mentoring program because the farmers had not yet mastered the isolation or propagation of biological agents and decomposer microbes.

Abstract

The objectives of the study are to determine the effect of both type and dosage of aquatic plants bokashi on the growth and yield of red onion in alluvial soil. The research design used was Factorial Completely Randomized Design (CRD) consisting of two factors, namely type and the dose of aquatic plants bokashi. The first factor consisted of three types of bokashi, i.e., giant Salvinia (Salvinia molesta), water cabbage (Pistia stratiotes) and water hyacinth (Eichornia crassipes), respectively. The second factor were four levels of bokashi dosage which were 0 tons ha-1, 10 tons ha-1 (0.2 kg/polybag), 20 tons ha-1 (0.5 kg/polybag) and 30 tons ha-1 (0.8 kg/polybag). The study was conducted from March to May 2017, located in the greenhouse of the Department of Agronomy, Faculty of Agriculture, University of Palangka Raya. The results showed that there was no interaction between the type and dose of bokashi on all variables observed. The dosage of bokashi affected plant height, leaf number, fresh weight and dry weight of biomass per clump, dry weight of bulbs and tuber diameter, but did not significantly affect the number of bulbs. The bokashi type did not significantly affect all observed variables. However, the water hyacinth bokashi tended to be better than other treatments

Abstract

Mangrove plants that usually grow on tidal swampland are very important as water storage as well as wave retention. Also, these kinds of plants are developed potentially as one source of natural insecticide. The use of botanical insecticide will reduce environmental pollution due to excessive use of chemical pesticides. The study purpose is to determine the effectiveness of extraction from several species of mangrove plants that act potentially as natural insecticides to control cabbage pests in tidal swamplands. The study was carried out using a complete randomized design, 4 treatments and 3 controls (i.e. chemical insecticides, botanical insecticide, and without insecticide), with 5 replications. The results showed that the mangrove species extract of buta-buta, bakau and jeruju as botanical insecticide was effective against cabbage crop pest, with value of average death of caterpillar in range from 86.00 to 86.67%.

Abstract

In an effort to increase crop production often faced with pest attacks. Major losses resulting in crop failure can occur if the disturbance is not handled properly. The yield loss due to Crocidolomia pavonana cabbage crop pests is quite high reaching 80%. This pest is often found in every planting season of mustard plants. In addition, this pest is also spread quite widely in dry land and wetlands (tidal swamps and lowland swamps). Pests are generally controlled by chemical insecticides. Excessive use of chemical insecticides will have a negative impact on the environment such as resistance, and killing of natural enemies of pests. As an alternative, plant extracts can be used as natural insecticides in controlling this pest. The purpose of this study was to determine the effectiveness of galam extracts against pest cabbage plants C.pavonana. The study was conducted at the Laboratory of Pests Disease Research Institute for Swamp Farming Banjarbaru, South Kalimantan in March - September 2018. This study uses a completely randomized design with 3 treatments with plant extracts, 3 treatments without control, and 5 repetitions each. Each treatment uses 15 larvae of C. pavonana instar 2 on fresh mustard leaves. Botanical insecticide is formulated by dissolving solid extracts. The results showed that the use of galam extract can suppress cabbage crop pests with a mortality rate reaching 90.67%

Abstract

One type of pest that often attacks soybean plant leaves in tidal swamplands is the armyworm pest. The intensity of leaf damage due to armyworm attack in tidal swamps ranges from 30-95%, and can even lead to crop failure. In controlling pests in soybean plants in general, always rely on chemical insecticides. The use of these chemical insecticides has a negative impact on the environment. To overcome this, the control is directed towards environmentally friendly pest control by utilizing swamp plants as a botanical insecticide. The study used a randomized block design (RBD) with 3 treatments of swamp plant extracts (galam, kirinyuh, kepayang) and 3 controls, namely without control, botanical insecticide made from neem, chemical insecticide with the active ingredient kloraniliprol. The aim of this study was to obtain a swamp plant extract that could be used in controlling armyworm pests (Spodoptera litura). The results showed that the three types of swamp plants could be used as botanical insecticides in controlling armyworm pests, and has an effectiveness value above 70%. The highest effectiveness of botanical insecticides was obtained at the age of 75 DAP, namely Galam (78.29%), Kirinyuh (78.86%) and Kepayang (78.85%).

Abstract

The irreversible drying indicated by the hydrophobic characteristic is one of the characteristics of peat which can be used to indicate the level of peatland degradation. Hydrophobic peat usually occurs as a result of fire or intensive drought which is mainly caused by peat land conversion. The objective of this research is to study the effect of land use on peat hydrophobicity, based on FTIR spectra and water penetration drop time. The result show that hydrophobicity characteristics of peat is influence by land use differences. The abandoned or scrub land has higher hydrophobic characteristic which indicated by slow water penetration time and the higher hydrophobic index based on the FTIR method, compared with rubber and palm oil plantation. Organic compounds that appear and cause peat to become hydrophobic include carboxyl, hydroxyl phenolic groups, and high lignin content.
