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.

Palembang: Penerbit dan Percetakan Universitas Sriwijaya (UNSRI).Fruitfly were the most detrimental pests in plant cultivation in Indonesia so that fruitfly were the main pests of horticultural crops, one of which was chili plants. This observation aimed to determine the percentage of fruitfly attacks on chili (Capsicum annum L. ) plants. The percentage of attacks was carried out by calculating the amount of plant damage used a formula to found out how much damage to chili plants. For the researched method used a literature studied. From the results of the studied, it was found that chili plants was attacked by Bactrocera carambolae and Bactrocera papayae. The percentage of fruitfly attacks on chili was calculated used the following formula; p (percentage of fruitfly attacks) = ???? (number of large chilies infested) divided by ???? (number of large chilies infested) plus ???? (number of healthy chilies) multiplied by 100 percent. In Pancasari village, Sukasada, Buleleng, the highest percentage of attacks was in the AVPP 1003-B line with a percentage of 66.49% and the lowest attacked was in the Kencana variety with a percentage of 23.82%. While in the Dusun Sandan area, Bangli village, Baturiti district, Tabanan regency, the highest percentage of attacks was in the AVPP 1004 line with a percentage of 31.02% and the lowest percentage was in the local variety Kencana, namely 4.12 %. The conclusion is that the largest attack between the two areas are in Pancasari village, Sukasada, Buleleng, in the AVPP 1003-B line with a percentage of 66.49%. And the lowest attack is in Sandan hamlet, Bangli village, Baturiti district, Tabanan regency on the Kencana local variety, which was 4.12 %.

Hamidson H, Singarimbu M, Umayah A. 2021. Cross-inoculation of the pathogen collectotrichum gloeosporioides in rubber, red chilli, papaya, and banana plant. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 142-153. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The aim of this study was to determine the relationship and the level of virulence of C. gloeosporioides on rubber, chili, papaya, and banana plants. The study used a factorial randomized block design consisting of two factors. The factors included 4 types of inoculum sources and 4 types of host plant factors. The results of observations on the growth of C. gloeospporioides on PDA media showed that C. gloeosporioides as a source of banana inoculum had the highest growth rate of 16.8 mm/day followed by papaya 14.29 mm/day, rubber 9.04 mm/day and chili 6.69 mm. /day. The fastest incubation period from the chili inoculum source was in the CbiPp 4 hsi treatment, from the rubber inoculum source was in the KiPp 6 hsi treatment, from the papaya inoculum source was in the PpiK 4 hsi treatment, and from the banana inoculum source was in the PsiK and PsiPp 4 hsi treatment. Observation of the number of spots showed not insignificant effect on the inoculum source factor, significant effect on the plant factor the interaction between the two factors. Observation of spot diameter showed a very significant influence on the inoculum source factor, plants and their interactions. Cluster analysis using hierarchical method showed that Ppi and Psi were very close, slightly far from Cbi and very far from Ki. The relationship of each plant could be seen in chili and banana which were very close, a bit far from rubber plants and very far from papaya plants. The closeness of C. gloeosporioides to the host indicated by the correspondence analysis was seen between Ki and papaya, Cbi to chili, Psi to rubber and Ppi closer to papaya.

The effect of intercropping chili with cabbage on pests and plant disease in Kerinjing Village Pagar Alam city. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp.101-113. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red chili (Capsicum annuum) belongs to the family Solanaceae and is one of the vegetable commodities that has many benefits, high economic value. The aim of this field practice is to find out the difference in intensity of pest and disease attacks on intercropping and monoculture chili plants. This field practice was carried out in Kerinjing Village, Dempo Utara District, Kota Pagar Alam, South Sumatra. The reseach uses the case method by deliberate sampling in a field by counting the number of mounds in the field and determining the sample on the mound to be observed. On the two fields that were observed were found pests and diseases that attacked the chili plants namely mandibular pests and curly diseases, yellow disease and leaf spot disease. The average intensity of mandibular pest attacks on monocultures is 2.7% while on intercropping is 11.12%. The mean intensity of attacks of curly diseases was 33.87% in monocultures and 22.35 in intercropping. In jaundice, the mean intensity of attack was 14.87% in monoculture land and 8.25% in intercropping land while the mean intensity of spotting was 5.67% in monoculture land and 1.30% in intercropping land. From the observations that have been made that there is no significant difference between monoculture land and intercropping land for pests and diseases of chili plants. Weather affects the attack of pests and diseases on both fields, where dry weather affects the spread of disease-causing vectors so that the intensity of the attacks is higher. And also the use of crop rotation that is not right also exacerbates the level of pest and disease attacks on chili plants.

Gustianingtyas M, Herlinda S, Anggraini E, Arsi A, Suwandi S, Hasbi H, Verawaty M, Setiawan A, Elfita E, Suparman S, Hamidson H, Khodijah K. 2020. Weight of spodoptera litura larvae and chili leaf area eaten after treated with some entomopathogenic fungal isolates. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Spodoptera litura is one of the important insect pests on chili in Indonesia that attacks the vegetative and generative phases. This study aimed to observe the effect of the entomopathogenic fungal isolates explored from the low and highlands on the decrease in feed and weight of S. litura larvae. The experiment was arranged in a Randomized Block Design (RBD) with 52 treatments consisted of 29 isolate of Beauveria bassiana and 23 isolate of Metarhizium spp. applied on 25 second instar of S. litura per replicate. The results showed that the body weight of larvae applied to B. bassiana isolates on the first day of observation was significantly different from the control. The body weight of larvae on the first day of observation of BJgTs isolates (0.30 g) and Bby (0.31 g) was significantly different and lower than the other treatments. The body weight of larvae applied isolate Metarhizium spp. significantly different from the controls. The body weight of larvae on the 9 day applied isolates MPdMs2 (4.74) and MKbTp2 (4.63) was significantly different from other treatments, the leaf area eaten was significantly different from the 7 day to the 12 day of observation. From this research, it can be concluded that B. bassiana isolates coded BJgTs and Bby, isolates Metarhizium spp. MPdMs2 and MKbTp2 codes are isolates that have an effect on reducing feed and larvae weight and cause changes in behavior of S. litura larvae.

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The cultivation of vegetable crops is very much practiced by farmers both in the highlands and in the lowlands. In the cultivation of vegetables, pests and diseases cannot be separated. Pests that attack cucumber plants can be detrimental both in quality and quantity. The purpose of this study was to determine the insect pests that attack cucumber plants. Observations were made by comparing 2 cucumber fields. The comparison of the 2 fields was then carried out using the t test method. The results of observations on cucumber plants in the field were 4 species of insect pests that attack cucumber plants. Insects that attack cucumber plants consist of Diaphania sp., Aulacophora similis, Bemisia tabaci and Liriomyza sp.. The population of insect pests was found only 3 species based on visual observation and the intensity of pest attacks on cucumber plants was found to be 4 species of insect pests that attack these plants. In the t test results on insect populations, the species of Bemisia tabaci were significantly different in land 1 and land 2, while Diaphania sp. And A. Similis is not real different. The intensity of insect pests of Diaphania sp., Aulacophora similis and Liriomyza sp. Unreal different. However, the intensity of the Bemisia Tabaci attack was significantly different. The intensity of insect pests attack on land 1 was 44.76%, while on land 2 was 42.97%. Cultivation of cucumber with technical culture affects insect pests and the intensity of pest attacks.

Arsi A, SHK Suparman, Hamidson H, Umayah A, Gunawan B, Pujiastuti Y, Pratama R, Pratiwi FA. 2022. The effect of technical culture on disease attacks on oyong (Luffa Acutangula) plants in Kuripan Village, Kecamatan Four Petulai Dangku. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 1011-1022. Palembang: Penerbit dan Percetakan Universitas Sriwijaya (UNSRI).The luffa plant/oyong is a fruit vegetable that is widely consumed by Indonesians in the form of fresh fruit The nutritional value of luffa is quite good because this fruit vegetable is a source of vitamins and minerals. Oyong plant is a climbing plant/vine. Oyong plants need a dry climate, with sufficient water availability throughout the season. Agricultural cultivation systems are never free from pests or diseases. In the field of farmers, there is not much knowledge about plant diseases or the causes of the disease itself. For this reason, this research practice aims to determine the effect of intercropping on disease attacks on Oyong (Luffa acutangula) plants. Field practice has been carried out in Kuripan Village, Empat Petulai Dangku District, Muara Enim Regency, South Sumatra Province from May to June 2022. The observation method used in this field practice is the direct observation method in the field which is carried out by determining the land, the land being taken has different cropping patterns. Then determine the plants to be sampled using the diagonal method. The data collected were primary data in the form of direct observation of symptoms in the field and secondary data obtained from farmer interviews. From the observation, there were 2 types of diseases, namely brown spots and virus mosaic.
