This study aims to increase the production of glutinous corn by applying mycorrhizal biofertilisers and NPK fertilisers. This research was conducted in Campagayya Village, Galesong District, Takalar Regency, South Sulawesi Province. This research was conducted from May to August 2022 in Campagaya Village, Galesong District, Takalar Regency. This study was structured using a split-plot design consisting of a main plot and subplots as the main plot was the application of mycorrhizal biofertiliser, which consisted of two levels: without mycorrhizal application and mycorrhizal application ten g/plant. As subplots, NPK fertilisation comprised 100, 200, and 300 kg/ha doses. Six treatment combinations were obtained from these two factors, and each was repeated three times to get 18 experimental units. The experimental results showed that the administration of mycorrhiza resulted in better growth and production of glutinous corn, shown by taller plants and heavier cob production. The interaction between mycorrhizal administration and 200 kg NPK/ha fertilisation resulted in a larger cob diameter of 55.54 mm.

The research aims to identify symptoms and analyze the effectiveness of phytoremediation of water hyacinth and water lettuce in lead-contaminated water. This research was conducted at Moncongloe Lappara Village, Maros District. Testing of water samples at the Laboratory of Soil, Plants, Fertilizer and Water Research Institute for Agricultural Technology, Maros. Plant samples tested at the Laboratory of Feed Chemistry, Hasanuddin University, Makassar, South Sulawesi. The study took place in July - August 2020. The research was an experimental study using a Randomized Block Design (RBD), which consisted of 2 experiments that used two types of aquatic plants: water hyacinth and water lettuce. The two plants were tested in artificial wastewater at concentrations of 0.43 ppm, 2.43 ppm, 4.43 ppm, and 6.43 ppm, followed by an analysis of water and plant samples in the laboratory. The observed parameters, namely plant morphology, heavy metal levels of lead (Pb), and phytoremediation effectiveness values. The results of the research show that aquatic plants, water hyacinths, and water lettuce can remediate water contaminated with lead (Pb). Even though the water hyacinth and water lettuce experienced symptoms of toxicity in the form of chlorosis and necrosis, these two plants were able to survive growth up to 15 days after planting. The phytoremediation ability of water hyacinth plants can reach an effectiveness of 82.27% with a reduction in metals in water that can reach 5.29 ppm. The phytoremediation ability of water lettuce plants can reach an effectiveness of 42.61% with a reduction in metals in water that can reach 2.74 ppm.

Bamboo root bacteria consist of pseudomonas and Bacillus polymixa bacteria, which can bind or fix nitrogen from nature. This study aims to determine the effect of the concentration of bamboo root bacteria on several varieties of long bean plants and the interaction between the concentration of bamboo root bacteria and types on the growth and production of long beans. This research was conducted from May 2022 to July at the Faculty of Agriculture, Fisheries and Animal Husbandry. Nineteen November University Kolaka. This study used a Randomized Block Design (RAK). The first factor is the long bean variety, which consists of 3 levels, namely V1 = Canton Tavi variety, V2 = Parade Tavi variety, and V3 = Pertiwi variety. The second factor was the concentration of bamboo root bacteria concentration treatment consisting of 3 levels, namely K0 = control, K1 = 5 ml/liter of water, and K2 = 7 ml/liter of water. This study consisted of 9 treatments, three replications, and 27 experimental units. The data were analyzed using analysis of variance and then continued with Duncan's test. The result of the research showed that the best long bean variety was Kanton Tavi (V1), and the best bacterial source concentration for long bean growth is 10 ml/liter air (K2), which was shown in the characteristics of plant length, number of leaves, number of pods per plant, and length of pods per plant. There was no interaction effect between the concentration of bamboo root bacteria and variety on all observed long bean growth and yield variables. The concentration of bacterial pathogens and types significantly affected the variables leaf length, number of leaves, 50% flowering age, number of pods per plant, and size of pods per plant.

Priming is one method to increase the viability and vigour of seeds that have experienced a decline. Priming materials consist of inorganic and organic priming studies to determine the effect of organic priming and soaking time on degenerated sweet corn seeds. The study was a completely randomized design with randomised and three replications. The first factor was the priming material type, consisting of four levels: without priming agent, PEG 6000 15%, coconut water 15%, and tomato fruit extract 15%. The second factor is the soaking duration which consists of two of The results showed that coconut water was the best organic priming agent and increased germination power, germination speed, growth uniformity, and corn seed germination dry weight of 6.33%, 4.29%/etmal, 6.17%, and 0.028 grams respectively compared to the seeds before priming, and when compared to the control, coconut water increased germination by 3.3%, germination speed by 2.8%/etmal, growth uniformity by 4.5%, and germination dry weight by 0.022 grams. Soaking the seeds for 24 hours gave better results than 12 hours for all observed parameters and there was no interaction. The type of organic priming material and the soaking time for all parameters were observed. Coconut water can be an alternative to inorganic priming in improving the ability of deteriorated sweet corn seeds.

The physiography of the catchment area at the foot of Mount Latimojong in the Mata Allo River is one part of the Saddang watershed, which is located in Baraka District, Enrekang Regency, South Sulawesi, covering an area of 15,915 km2. Land use patterns in the Saddang sub-watershed include forest, shrubs, coffee plantations, pepper fields, upland rice, corn monoculture and peanut-corn intercropping. This watershed needs serious attention because most of its area is on a slope of 15-40%, with erosion hazard (EHL) varying from mild to severe erosion. The loss of soil organic carbon (C-organic) is measured from the soil carried along with runoff, and its magnitude depends on the land use type. The results of the measurement of soil organic matter loss on forest land use were 13.25 kg/ha, bushland 59.55 kg/ha, coffee plantations 365.91 kg/ha, pepper gardens 321.2 kg/ha, paddy fields 383.80 kg/ha, corn monoculture 427.91 kg/ga, corn-peanut intercropping 168.26 kg/ha, and open land without vegetation 659.86 kg/ha. Forest and bushland are the best in conserving soil organic matter. Still, it is economically unprofitable for the community, so the pattern of land use for corn-peanut intercropping can be used as an alternative to agricultural business to maintain and conserve organic C (soil organic matter).

The very low productivity of Ultisol and many inhibiting factors in its utilization make this soil not widely used as agricultural land, especially for vegetable cultivation. Giving chicken manure compost is an alternative to increase Ultisol productivity. This study aims to determine the productivity of Ultisol, which has been composted with chicken manure for land kale (Ipomea reptans Poir). The experiment was conducted at the Green House of the Faculty of Agriculture, University of Muhammadiyah Makassar. The experiment was amending Ultisol with chicken manure compost at 0 t/ha, 10 t/ha, 20 t/ha, and 30 t/ha arranged using a Randomized Block Design (RBD), which was repeated three times. Ultisol that has been processed in such a way and dried weighed 2 kg/polybag, planted with land kale seeds to evaluate the growth of these plants during the experiment. The final result of this experiment is to get an overview of Ultisol soil productivity after improving chicken manure compost, mainly to be used as vegetable land. The results of the experiment showed that chicken manure compost was able to provide good growth of land kale on Ultisol. Chicken manure compost of as much as 30 t/ha gave the highest yield of all parameters observed in land kale plants. However, a dose of 20 t/ha chicken manure compost increased the productivity of Ultisol soil, especially in its use as vegetable farming land.

In Indonesia, attacks by armyworm caterpillars often occur on soybeans, cabbage, tomatoes and onions. Farmers still rely on synthetic insecticides to control pests that have been carried out so far. In addition, farmers who use insecticides generally exceed the recommended dosage, which can disrupt ecosystems and human health. This research aims to activate the effectiveness of papaya leaf, taro leaf and tobacco extracts on the death of grayak caterpillars on tomato plants (Lycopersium esculentum M.) to reduce insect mortality. Additionally, the most potent doses of this extract are sought after. The Makassar City Industrial Research and Development Center and the Indonesian Muslim University Pest and Disease Laboratory both participated in this research, which took place from March to May 2023. The equipment used included blenders, buckets, filters, jerry cans, plastic bottles, sprayers, Petri dishes, glasses, measuring spoons, stirrers, markers, name tags, and stationery. Meanwhile, the ingredients consist of 3 litres of air, 1 kilogram of papaya leaves, cigarettes and taro each, 1 litre of sunlight each, and 500 ml of 5% alcohol each. The research experimental design was a Completely Randomized Design (CRD) with five treatments, namely Control (P0-), Chemical pesticide (abenz), P1 (25%), P2 (50%) and P3 (75%) with three replications. It takes 15 insects because there are five insects per repetition. The results of this research were obtained. The greater the concentration of biopesticide in papaya leaves, tobacco leaves and taro leaves used, the greater the mortality of pests in the plants. 75% concentrate of papaya leaf biopesticide, tobacco leaves and taro leaves can be used as vegetable biopesticides because they contain active compounds that can harm plant pests.

This study examined fermented cocoa beans' physical and chemical qualities from six superior cocoa clones in South Sulawesi. The locations for sampling the cocoa pods were North Luwu Regency and Bantaeng Regency. This research was arranged using a randomised block design (RBD), which consisted of 6 treatments, namely clones MCC 01, MCC 02, Sulawesi 01, Sulawesi 02, Local, and clone GTB with three replications. Data were analysed using ANOVA, and if there was a significant effect, it was continued with the Least Significant Difference (LSD) test at the 5% level. Parameters observed were bean size (number of seeds per 100 gram), moisture content, fat content, pH and total titrated acid. The results showed that the MCC 02 clone gave the best results on the number of seeds per 100 grams with an average number of grains of 53.50 (AA quality), 52.99% fat content, 6.68% moisture content, pH 5.43, and total acid titrate 7.93%.
