Abstract

Sari, D. D., Sulaiman, F., Irmawati, I., Rethanasya, D., Sonnia, R. R., Damayanti, S. H., Pamungkas, R., Miralisa, A. T. (2024). Growth and yield of cassava alabio plants (Dioscorea alata L.) given liquid organic fertilizer (POC) from goat manure. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 235–243). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Ubi alabio (Dioscorea alata L.) is a type of yam plant that is widely cultivated in lebak swamplands and is classified as a shrub and grows vines with a length of 3-10 metres. Problems that are still faced by many farmers, namely the presence of pest attacks by caterpillars, beetles and aphids so that good tillage and plant maintenance are needed. This study aimed to determine the optimal growth results of alabio sweet potatoes with the use of Liquid Organic Fertiliser from goat manure. The method used is Randomised Group Design (RAK), which is a repetition method. The results of this study that the goat manure POC factor consists of 5 levels with 5 replicates and each replicate consists of 5 plants, so that the number of plants observed is 125 plants. In stem length, goat manure POC affects plant growth, stem length is increasingly influential at week 4 after planting, but at week 16 the plant has no real effect. In the analysis of stem height observations, goat manure POC had no significant effect on the growth of the main stem height with the highest number of 546 cm at 16 weeks after planting. For the number of leaves, POC has no significant effect on the observation variable time at the highest result is at 291.8 at 16 weeks after planting. In the observation of the number of branches, goat manure POC had no significant effect on the number of branches, for the highest results obtained at 6.44 at 16 weeks after planting. This study concluded that the use of POC from goat manure can be a good alternative to increase agricultural yields, although it is necessary to choose the right concentration to achieve optimal results.

Abstract

Irmawati, I., Sefrila, M., Susilawati, S., Tambunan, R. T., Poerbaputra, Y. D., Sinaga, A. P. P., Praptawara, M. Y. A., Hutabarat, R. V. M., Simanjuntak, R. (2024). Morphophysiological characteristics and production of bima brebes shallot variety by providing liquid organic fertilizer in a floating cultivation system. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 202–211).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Shallot cultivation requires the application of technology that is appropriate to the conditions of the agroecosystem plants being planted in order to provide high yields. This research aimed to determine the growth and yield of shallot plants of the Bima Brebes variety which are cultivated using a floating farming system with the addition of liquid organic fertilizer. This research was structured using the Randomized Group Design (RAK) method by carrying out 4 treatment levels, namely P0 = Control (100% NPK), P1 =4 mL L-1POC, P2 = 8 mL L-1 POC, P3 = 16 mL L-1 POC. The results of the diversity analysis showed that the application of liquid organic fertilizer (POC) given to the plants showed that the results were not significantly affected in all growth parameters of the shallot plants. Parameters observed included plant height, number of tillers, number of leaves, level of greenness of leaves, fresh weight of berries, fresh weight of tubers, dry weight of berries, air dried weight of tubers, and tuber diameter. The best leaf length of shallot plants was found in treatment P3 with plant height reaching 32.37 cm. This shows that liquid organic fertilizer can meet the nutrient needs of shallot plants for plant height growth. Research shows that the application of liquid organic fertilizer with treatment at a dose of 16 mL L-1 is able to provide the best results for all parameters of growth and yield of shallot plants.

Abstract

Susilawati, S., Haqqi, V. D., & Irmawati, I. (2024). The application of chicken manure fertilizer on the growth and yield of shalot (Allium ascalonicum L.) plants of the tajuk variety in a floating system. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 799–816).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Shallots are one of the plants that produce economically valuable bulbs that can becultivated conventionally or with a floating farming system. The purpose of this study was to determine the impact and best dosage of providing variations in chicken manure fertilizer with a floating system on the growth and yield of shallots (Allium ascalonicum L.) tajuk variety. This research was conducted at the Embung Faculty of Agriculture, Sriwijaya University with coordinates 003 ° 13'16 "LS and 104 ° 39'03" BT in July to August 2024. The study was conducted using a Randomized Block Design (RAB) consisting of 4 treatments and 3 replications. The variation of fertilizer doses used in this study were P0 = Control (Without chicken manure fertilizer), P1= 10 Tons/ha (40 grams of chicken manure fertilizer/polybag, P2= 20 Tons/ha (80 grams chicken manure fertilizer/polybag), P3 = 30 Tons/ha (120 grams of chicken manure fertilizer/polybag). The parameters observed were plant height, number of leaves, leaf area, leaf greenness level per week, leaf greenness level per hour, leaf growth age, fresh weight of shoots, dry weight of shoots, number of tillers, number of bulbs, bulb length, bulb diameter, bulb volume, fresh bulb rice, air dried of bulb weight, and root length. The results of the study showed that variations in the dose of chicken manure fertilizer did not have a significant effect on the growth and yield of shallots planted in a floating system. Even so, a dose of 10 tons/ha or 80 grams/polybag (P2) produced better growth and production than other treatment.

Abstract

Inaya, R., Irmawati, I., Susilawati, S., Helen, H., Herlin, W., & Negara, Z. P. (2024). The effect of different sterilization techniques on the contamination levels of duku leaf midrib explant in In-Vitro Culture. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 667–678). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Duku plant (Lansium domesticum) is one of the popular tropical fruit in indonesia. Using the idea of plant cells' totipotency, tissue culture is an alternate method for a quick and massive propagation of high-quality duku plant seedlings. This research was aimed to evaluate different sterilization materials and procedures on duku leaf midrib explants through tissue culture. The research was conducted from June to September 2024 at Tissue Culture Laboratory, Department  of  Agronomy, Universitas Sriwijaya (2°59’23.4”S 104°43’53.4”E). A combination of  sterilizing substances, including 70% alcohol, fungicide, bactericide, liquid detergent, and NaOCl, were utilized in this sterilization procedures. The percentage of live explants, browning explants, and explants infected with bacteria or fungi then were calculated using parametric descriptive analysis. The results showed that the P3 treatment's sterilant combination liquid detergent for 3 minutes, 0.2% of fungicide and bactericide for 10 minutes, 1% NaOCl for 15 minutes, and 70% alcohol for 5 minute produced the highest percentage of live explants (46%) with a relatively low percentage of contaminated explants (30%) and the lowest percentage of browning explants (23%). Thus P3 treatment was concluded as the best treatment to reduce the contamination level and browning of duku leaf midrib explant.

Abstract

[GROWTH AND HARVESTING FREQUENCY OF RED CHILI PLANTS WITH THE APPLICATION OF  NPK FERTILIZERS CULTIVATED ON SUB-OPTIMAL LAND IN FLOATING CULTURE SYSTEM]. The low productivity of red chili in South Sumatra is mostly due to its cultivation was conducted in sub-optimal land that is less favorable for producing vegetable crops. This study aimed to evaluate growth and yield of red chili plants under suboptimal conditions using various doses of NPK fertilizer. The experiment was carried out from June to October 2022, at the water reservoir and experimental field (as a comparison) at the Faculty of Agriculture Universitas Sriwijaya, Indralaya, South Sumatra with an altitude of 10 m above sea level. Both experiments were arranged in a randomized block design with three replications and one factor in the group, namely NPK fertilizer doses (0, 5, 10, and 15 g/polybag). For the experiment in the water reservoir, each treatment was arranged randomly in a 200 cm x 100 cm bamboo raft (for each group). The results showed that the application of NPK fertilizer in floating cultivation did not increase plant height, number of leaves, shoot diameter, and harvesting frequency of red chili. It was concluded that the application of NPK fertilizer in floating cultivation did not increase growth and harvesting frequency of red chili.
