Abstract

Weeds always appear in minimal or intensive tillage and cause less optimal growth of cucumbers. This study aims to determine the effect of arthropod diversity on the surface of cucumber plants with weed and non-weed land treatments. The research was conducted in the village of Ujanmas Baru, Muara Enim Regency, South Sumatra. Arthropod observations were carried out using 3 visual methods, pantrap and pitfall traps and the results were analyzed using the calculation of Diversity Index (H'), Individual Distribution (E') and Dominance Index (C). The index obtained in the pitfall traps of the study area with no weeds and weeds in the vegetative and generative phases was categorized in the medium category (H'= 0.56-1.27). The dominant index value of soil arthropods in pitfall traps treated on non-weeds and weeds in the vegetative and generative phases was categorized in the high category range (D = 0.35-0.82). However, in this study the species caught in pan traps were treated on non-weed land and weed land with a diversity index (H') categorized as moderate and a dominant index value (D) categorized as low. The conclusion of this study was that the species of arthropods found in cucumber plants treated with weeds and no weeds did not significantly affect the diversity of arthropods on the cucumber soil surface. Arthropod diversity in cucumber plants in both treatments with pitfall traps and pantrap included in the moderate category with the highest diversity index values of 1.27 and 2.19. Arthropod insect pests found on the surface of the cucumber planting soil consisted of 4 orders and 8 families dominated by Collembola sp and Acheta sp.

Abstract

BBTV (Banana Bunchy Top Virus) is a viral disease that attacks cultivated banana plants and can cause stunting. The symptoms of BBTV disease attack on banana plants are narrowed, piled up leaves and stunted plants. The disease is caused by an insect vector. Pentalonia nigronervosa is the vector insect that transmits BBTV disease. The purpose of the research was to see the java turmeric plant as an alternative host for population growth and BBTV disease vector. The method in the study used a Randomized Group Design. This treatment consists of two treatments with 10 replications. Based on the results of research conducted on the population of P. nigronervosa experienced fluctuations, but high growth in water media. BBTV disease that attacks banana plants in each treatment has the highest incidence in the control treatment, namely, 73.33% dan the lowest disease incidence the turmeric treatment was 6.67%. The highest intensity of BBTV disease attack in the control treatment was 42.06%, while the lowest in the Javanese turmeric treatment was 1.50%. P. nigronervosa inoculated on Javanese turmeric for 72 days can suppress BBTV disease transmission. However, based on the analysis of each treatment, no significant differences were found. P. nigronervosa has the highest population in the soil medium 95.4 individuals and water medium 86.7 individuals. The population of P. nigronervosa has a good development in turmeric plants.

Abstract

Pujiastuti et al, 2017. Production of Bacillus thuringiensis Spores in Agricultural Waste with Addition of Golden Snail Shell Powder and its Toxicity Against Spodoptera litura Fabr. (Lepidoptera: Noctuidae). JLSO 6(2):150-157.Armyworm or Spodoptera litura is an important pest on the cultivation of plants. Controlling by using biological agents such as Bacillus thuringiensis is an alternative to the use of chemical insecticides which cause a negative impact on insects and environment. B. thuringiensis-based bio insecticide can be reproduced by using agricultural waste with the addition of golden snail shell flour. The study was aimed to investigate the production of B. thuringiensis spores on agricultural waste media and the addition of golden snail shell flour and its toxicity to armyworm, as well. The research design was a completely randomized design with 10 treatments and 3 replications. Treatment were the media of agricultural waste: 50 mL coconut water, 50 mL of tofu liquid waste, 50 mL of rice wash water and mixture of three media (v/v/v, 1:1:1) with the addition of golden shell flour as much as 5 g and mineral salt of CaCl2, MgSO4, K2HPO4, KH2PO4. The results showed the production of bacterial spores ranged from 8.90x107 spores/mL to 9.51x107 spores/mL with the highest production in the mixed treatment of the three waste media (coconut water, tofu waste and rice laundry water). In this treatment the level of toxicity was 40% in larvae of armyworm. The weight of leaf feed consumed by armyworm at various treatments was ranged from 36.33 to 46.67 g/10 larvae. The addition of mashed shell flour to growth media of B. thuringiensis did not increase the number of spores.

Abstract

Astuti et al, 2018. Utilization of Organic Waste in the Making of Bacillus thuringiensis-based Bioinsecticides as Agents for Control of Caisim Brassica juncea Pests. JLSO 7(2):136-143. Bacillus thuringiensis was one of the entomopathogenic bacteria that can produces toxic crystal proteine (ᴕ-endotoksin). The use of bioinsecticide as a biological agent in pest control was one component of integrated pest control (IPM). The aimed of this reseacrh was to know the population of pests in plants and the percentage of damage to plants that exist in each treatment. The research was conducted in a vegetable garden in the Banyuasin district in November 2017 until January 2018. The research method used a randomized block design with 5 treatments and 4 blocks. The treatment was Bacillus thuringiensis KJ3R5 cultured in coconut water and rice washing water  (A), Bacillus thuringiensis LC2 cultured in coconut water and tofu wastewater (B), commercial Bacillus thuringiensis (C), inorganic insecticide (sidametrin) (D), and water as control (E). The variables observed were arthropod populations on the canopy and ground surface of choy sum (Brassica rapa var. parachinensis or Brassica chinensis var. parachinensis) plants. The results showed that 4 species of pests i.e. Pyllotreta crucifera, Spodoptera litura, Plutella xylostella, and Helula sp. Treatment with Bacillus thuringiensis LC2 (B) resulted in reduction of plant damage by 61%.

Abstract

Bacillus thuringiensis is an entomopathogenic bacterium isolated from the soil and  has been widely used as an active ingredient in the manufacture of bioinsecticides. The target insects are very specific and depend on the type of protein content. Epilachna sp. are important insect pests because both larvae and adults as plant-eating pests. The research aimed was to investigate the effectivity  of  B. thuringiensis against the larvae of Epilachna sp.. B. thuringiensis- bio-insecticide was prepared using isolates originally from freshwater swamp soil of South Sumatra (SMR04). Epilachna sp larvae were mass-reared with Solanum torvum leaf feed in the laboratory. The design used was a completely randomized design, with 6 treatments and 5 replications. Treatments were spore concentration contained in the bioinsecticide solution included: 1 x 108, 1 x 107, 1 x 106, 1 x 105 spores/mL, commercial bio-insecticide and without treatment as a control. Each replication used 10 individual of the 2nd larvae. Statistical test results showed larval mortality in B. thuringiensis treatment was significantly different from commercial bio-insecticide treatment. The highest mortality of bio-insecticide treatment occurred at a concentration of 108 spores/ml (40.00 %) and the lowest was at a concentration of 105 spores/mL (18.01 %). The lowest LT50 value of bio-insecticide treatment was at a concentration of 108 spores/mL, namely 79.37 hours. The control of larvae included in the Coleoptera order was still not satisfactory yet, considering the presence of protein content in B. thuringiensis strain SMR04 which did not match the type of protein required.

Abstract

Integrated Pest Control in Chili Plantations with a Focus on Bioinsecticide Applications with Active Ingredients Bacillus thuringiensis. Bacillus thuringiensis is an entomopathogenic bacterium that plays important role in controlling plant pests. These bacteria can be propagated with agricultural waste media producing bioinsecticides. The use of bioinsecticides for controlling insect pests on chili plants was done through community service activities. The activity was carried out in Tanjung Baru Village, North Inderalaya Sub-district, Ogan Ilir Regency, South Sumatra, from August to October 2021. As one of the chili producing centers, farmers in Tanjung Baru Village grew chili almost all year round. Insects pests attacing chili plants were aphids, thrips, armyworms and fruit flies. Control is mostly done with synthetic insecticides, which are often mixed. Control activities focusing on the use of bioinsecticides with B. thuringiensis-based were carried out to overcome this problem. An initial demonstration plot was made for farmers to see the results of the experiment. The next stage farmers were given skills to make these bioinsecticides. To measure the success of the activity, a feedback survey was conducted amongfarmers. The survey results showed 80% of farmers were interested in using B. thuringiensis-based bioinsecticide and intended to use it. Regarding the skills of making bioinsecticides, more than 90% were interested in making their own, because waste materials as a medium for propagation were available in abundance. Chili farmers in Tanjung Baru Village can receive information from outsiders and showed a desire to change their old habit (use of chemical insecticides) to switch to biological control.

Hal ini, dikarenakan masyarakat belum mengetahui kandungan gizi, vitamin dan mineral sayuran untuk memenuhi nutrisi dalam tubuh manusia. Hama dan penyakit dalam budidaya sayuran masih menjadi permasalahan. Untuk mengurangi permasalahan tersebut perlu dilakukan pengendalian hama dan penyakit yang ramah lingkungan. Pengendalian yang ramah lingkungan menggunakan tanaman-tanaman yang ada di desa tersebut. Tujuan pengabdian ini untuk budidaya sayuran dan pengendalian organisme penganggu tanaman menggunakan pestisida nabati. Metode dalam kegiatan ini dengan melakukan penyuluhan secara langsung. Penyuluhan penggunaan budidaya tanaman sayuran dilakukan menggunakan metode ceramah serta pendampingan. Berdasarkan hasil sosialisasi pengendalian hama dan penyakit tanaman dengan menggunakan tanaman sudah dilakukan oleh masyarakat. Akan tetapi, kegiatan ini dilakukan secara tradisional dengan merendam bagian tanaman selama 24 jam. Pemanfaatan tanaman sebagai pestisida nabati masih sedikit dilakukan oleh masyarakat. Hal ini dikarenakan budidaya sayuran masih sedikit dilakukan dan beberapa tanaman saja. Kesimpulan pengendalian mengunakan pestisida nabati sudah dilakukan oleh masyarakat dan masih sedikit. Budidaya sayuran paling banyak di tanam yaitu, cabai dan terung.   Kata Kunci: pestisida, nabati, pengendalian, sayuran
