Abstract

Sulaiman, F., Aritonang, A. G. A., Habibah. D.F., Sitompul, G. E. Y., Trijayanti., S., Yuniarti, Y., Sitorus, V.J.R. (2023). Hydroponic lettuce cultivation at the agricultural technology assessment Center Jalan Mentok, Bangka Belitung Islands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 230-236).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Lettuce is an agricultural product that is generally consumed in fresh form to produce good hygiene. For the benefit of human beings, which is a top priority, as the population of Indonesia increases, market demand in the food sector will also increase. The aimed of this research is to give the students work experience and knowledge in the field of hydroponics. The methods used in this study were observational and participatory. Results of this study were obtained when the 2nd DAP (Day After Plantation) carried out a nutritional solution check. Since the salad is already quite large and the nutrients are reduced, first nutritional addition was made to 425 ppm with Ph 6.1. Second nutritional component was added at 14 DAP to 570 ppm at pH 6.4.Third nutritional addition at 24 DAP was 745 ppm at pH 6.7. Fourth nutritional addition at 31 HST until the harvest was 800 ppm at pH 6.8. The nutrient solution is an important factor in this study because it is a determinant of the success of hydroponic cultivation. A nutrient requirement that is effectively met for the celery can make its growth more optimal. Generally speaking, hydroponics requires essential nutrients consisting of macro and micronutrients. The advice that can be given is need to increase the sustainability of hydroponic crop cultivation activities in the greenhouse as well as improve development on the basis of IoT (the Internet of Things) for automatic nutrition systems so that the quality of the plants produced is even better.

Abstract

Susilawati, S., Sodikin, E., Sulaiman ,F., & Irmawati, I. (2023). The effect of bulb size on the initial growth of three varieties of shallot (Allium ascalonicum L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 151-162).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Both vegetative (using bulbs as planting material) and generative (using seeds) methods can be used to cultivate shallot plants. Although using bulbs is simpler, it has a number of drawbacks, including the need for more seeds, relatively high costs, and the challenge of planning a planting timetable. In order to support the growth of three types of shallots, this study sought to assess the strength of the correlation and regression models of the bulb features.  The study was carried out during June and July 2023 in Tanjung Pering Village, Indralaya Utara Subdistrict, Ogan Ilir, South Sumatra, at coordinates 003 13'00" LS and 104 38'16" E. A Randomized Block Design with two components and three replications was employed in the study. The first factor is the utilization of three different varieties: Bauji, Bima Brebes, and Tajuk. The second component is bulb size, which comes in three sizes: small (1.5 cm), medium (1.5 cm to 2.0 cm), and large (>2.0 cm). The research plot measured 150  cm by 100 cm, and each treatment plot had 21 plants. The parameters that were measured included the bulb character, which included the diameter, weight, length, and volume of the bulb, and the bulbs initial growth, which included the leaf length, number of leaves, tillers, and SPAD value. Based on the coefficient of determination (R2), the findings demonstrated that the linear zero-intercept model consistently performed better than other regression models in correlating bulb diameter with bulb length, weight, and volume. The Tajuk variety had the most leaves and tillers but the lowest SPAD score when varieties and bulb sizes were combined early in growth. Shallot plants develop best in their early stages on little bulbs. Conclusion the most accurate model for correlation between bulbs characters uses a zero intercept linear regression model.

Abstract

Khamsaldin, S. G., Yakup, Y., Budianta, D., Sulaiman, F, (2023). Adaptability of gogo rice in rubber plant area produces. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 327-332).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Gogo rice is a dryland tolerant crop and can be grown as an intercrop under stands. However, the shade of standing plants is an obstacle to its growth in plantation land, so efforts are needed to obtain gogo rice varieties that are tolerant to shade conditions. This paper aimed to assess the development of hope strains of gogo rice that have multi-tolerant properties to biophysical conditions of drought stress that are resistant to shade through evaluation of the adaptability of selected gogo rice strains. The purpose of this study was to obtain new varieties of shade-resistant gogo rice from 5 shade-treated varieties of gogo rice. 5 varieties of gogo rice. Research was conducted on the growth and production of shade-tolerant gogo rice varieties and NPK doses (50 kg/ha, 75 kg/ha, 100 kg/ha). Genetic information is useful for obtaining new high-yielding varieties of gogo rice. This study begins with seed germination. This research was conducted at the TPH Provincial Agriculture Office. Sumsel. Tools used: polybags, paralon pipes, stationery, This study used a split plot design. This study consists of 2 factors, namely the shade factor (N) as the main plot and the variety factor (V) as the child plot. The watering factor as the main plot consists of 4 levels, namely: N1 = watered every 3 days, N2 = watering every 6 days. While the varietal factor as a plot consists of 5 (five) treatment levels, namely: V1 = Variety 1, V2 = Variety 2, V3 = Variety 3, V4 = Variety 4, and V5 = Variety 5. In total there were 4 main plots and 5 subplots with each treatment repeated 3 times with each trial unit repeated 3 times so that 60 polybags were obtained. Measurements of plant growth variables include: plant height (cm), number of leaves, number of saplings, leaf area (cm2): Calculated using the formula: LD (cm2) = ( p x l x k x n), where p = maximum leaf length, l = maximum leaf width, k = correction factor, n = number of leaves in one plant. Observations of yield variables include: total fresh weight of plants (g) and total dry weight of plants (g), number of productive tillers, panicle length (cm), number of panicle seeds (seeds), weight of seeds per plant, weight of 1000 seeds and % of hollow seeds per plant, proline content. The data collected were analyzed by variety analysis (Test F) at the level of 5%. If there is a noticeable effect (F test 5%) then proceed with the Isolated Real Difference Test (BNT) at the level of 5% to determine the difference between treatments.

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.
