This research aims to determine the potential of the botanical pesticide papaya leaves and neem leaves treated with aloe vera leaf adhesive and without aloe vera leaf adhesive in controlling leaf pests on mustard greens in the Unlam Faculty of Agriculture Experimental Garden. The design used in this research was a one-factor Completely Randomized Design (CRD) with 5 treatments and 4 replications. Each experimental unit consisted of 4 polybags with 2 mustard plants planted in each polybag. Overall in this study there were 160 mustard plants, treatments consisted of K = Control (water), P1 = Papaya leaf solution + aloe vera leaves, P2 = Neem leaf solution + aloe vera leaves, P3 = Papaya leaf solution without aloe vera leaves, P4 = Neem leaf solution. The results of this study showed that all Botanical pesticide treatments sprayed on mustard greens showed no difference, namely P1 = (42.33%), P2 = (38.82%), P3 = (37.53%), P4 = (36.92%). However, it is significantly different from the control, 47.69%. The lowest leaf pest attack was seen in the neem leaf (P4) 34.92%.

There are many problems and negative impacts caused by insects on chili plants (Capsicum annum L.), so one alternative environmentally friendly control method is to use insect traps, one of the traps that can be used is the yellow trap. The aim of this research is to find out how effective yellow traps are against pests in red chili plantations. This method uses a completely randomized design (CRD) with one factor consisting of four treatments (T1 30 cm, T2 60 cm, T3 90 cm and T4 120 cm), which was repeated 6 times. The results of this study showed that all yellow trap treatments showed that the treatment in the first to sixth weeks had no real effect on trap setting and tended to decrease the number of catches. It was found that the percentage of insect intensity in the observations showed that the highest percentage figure for the T3 treatment was 3.81%, while the lowest percentage figure for the T1 treatment was 3.28%.

Entomopathogens are microorganisms that can cause disease in insects. Entomopathogenic fungi are one type of bioinsecticide that can kill insects by infecting them through the skin, digestive tract, spiracles and other holes. This research aims to identify entomopathogenic fungi from around oil palm plants. The method used in this research began with a survey and purposive sampling of soil samples taken at the oil palm plantation of PT Mulia Agro Permai Timur Sampit, Central Kalimantan. Samples were taken at five different points, one sample was obtained at each point at a depth of 15-20 cm. From the isolation results, five types of isolates were obtained, namely the fungi Penicillium spp., Mucor spp., Trichoderma spp., Metarhizium spp., and Beauveria spp. From the Koch Postulate test using Hong Kong caterpillar larvae (Tenebrio molitor) as test larvae which were inoculated with entomopathogenic fungi. The results showed that the five fungus isolates were able to cause death in the test larvae with different death times for each isolate.

A monophage herbivorous insect called S. pectinicornis can be utilized to biologically control the weed Pistia stratiotes. Insect mass reproduction followed by release into the target weed area is one technique that can be used. The quality of the feed must be taken into consideration during maintenance in order to increase the fitness of S. pectinicornis insects and enable them to function at their best. The fertilization procedure can improve the nutritional value of P. stratiotes as a feed source. The experiment involved applying NPK fertilizer to P. stratiotes at 6 different levels: 0 g (control); 5 g; 10 g; 15 g; 20 g; and 25 g. The findings demonstrated that when NPK fertilizer was applied to Pistia stratiotes, S. pectiniconis larvae, pupae, and imago had a better chance of surviving than controls. S. pectinicornis showed improved insect growth and development since its lifespan was shorter than controls at every developmental stage. The ideal NPK fertilizer dose for maintaining Pistia stratiotes as feed during S. pectinicornis propagation is 15g/20 L of water.

Shallots are one of the most important commodities in the market and they are easily damaged/rotten. This is due to several factors, including natural factors that often occur and cannot be predicted. One of these natural factors is plant-disturbing organisms. Some of them belong to the phylum Arthropods. This study aims to determine the effect of giving some botanical pesticides on shallots to the diversity of arthropods in the soil in peatlands and to determine the abundance of arthropods. This study used a one-factor Randomized Block Design (RBD) consisting of five treatments, namely without pesticides, chemical pesticides, kirinyuh leaf extracts, kepayang seed extracts and galam leaf extracts with four replications, so that there were 20 experimental units. The parameters observed were arthropod type and abundance. There was an effect of giving botanical insecticides on the diversity of arthropods and the evenness of arthropod species in shallot plants on peatlands. The highest diversity was in the control treatment (1.49) and the lowest diversity was in galam leaf extract (0.96). The highest abundance of arthropods was in the group of arthropods of the scavenger type, which indeed dominated the soil by 86.67%.

This study aims to examine the life balance of the biological control agent Spodoptera pectinicornis fed Pistia stratiotes with NPK and AB mix fertilization.. The research was carried out from March to May 2021 at the Laboratory Pengendalian Hayati and Greenhouse Entomology Faculty of Agriculture University Lambung Mangkurat Banjarbaru. The data in this study were analyzed descriptively by calculating the population. S. pectinicornis in one life cycle. There are 3 treatments and 3 replications on the 100 egg s. pectinicornis, The highest gross reproductive rate (GRR) was in the AB mix treatment of 1912 individuals/generation. The highest net reproduction rate (Ro) was found in the AB mix treatment of 129.520. The average value of the shortest generation period (T) in the NPK fertilizer treatment was only 26.334 days. The highest intrinsic growth rate (r) was found in the AB mix fertilizer treatment of 0.164 individuals/parent/day. The calculation of the limited growth rate (λ) showed that the AB mix treatment had the highest population increase of 1,174 individuals/parent/day. Apu wood treated with NPK and AB mix fertilizers can increase the rate of population development in the life table of the insect S. pectinicornis.

Potensi Asap Cair Tandan Kosong Kelapa Sawit Untuk Menekan Pertumbuhan Gulma Teki (Cyperus kyllingia): Potential of Liquid Smoke from Empty Palm Oil Bunches To suppress the growth of Cyperus kyllingia Khairunida, Khairunida; Soedijo, Samharinto; ., Salamiah

C. kyllingia is an annual weed that can cause problems because it can reduce the quantity and quality of cultivated plant production, so this weed needs to be controlled. Weed control with synthetic herbicides is currently more popular because its effectiveness can be seen more quickly. However, if synthetic herbicides are used for a long period of time, they will affect soil conditions. Therefore, an alternative weed control using liquid smoke from empty oil palm fruit bunches (TKKS) is needed. The research aims to determine the potential of TKKS liquid smoke in controlling the growth of sedge weed (C. kyllingia). The design used a 1 factor Completely Randomized Design consisting of 5 treatments and 5 replications with liquid smoke concentrations of 0%, 8.3%, 16.6%, 25% and 33.3%. Research shows that TKKS liquid smoke has the potential to be used as a natural herbicide because it has an effect on suppressing the growth of the C. kyllingia weed. The best concentration that can suppress weed growth is 33.3% liquid smoke.
