Abstract

The long-term dependence of tobacco farmers on synthetic chemical fertilizers may reduce soil quality and crop productivity. One of the main challenges in tobacco production is producing high-quality seedlings that can support optimal plant productivity. This study aimed to determine the best bioagent treatment to tobacco. The used a non-factorial randomized block design with four growing-media treatments: P0 (control), P1 (Azotobacter), P2 (Biohumic), and P3 (Azotobacter + Biohumic). Each treatment was replicated three times. The results showed that the combination of Azotobacter and Biohumic (P3) produced the highest mean values for all observed plant growth parameters. This response was presumably associated with the synergy between nitrogen fixation by Azotobacter and improved nutrient availability and root-zone conditions by Biohumic.

Abstract

Palm kernel meal is a byproduct of the palm oil industry that possesses good nutritional potential but is limited by its high crude fiber content. Fermentation using the bacterium Bacillus cereus V9 can serve as a solution to reduce crude fiber and enhance the nutritional value of palm kernel meal, thereby potentially replacing a portion of commercial feed. This study aims to determine the optimal level of commercial feed replacement with fermented palm kernel meal (BISF) on broiler body weight gain. This study employed a completely randomized design (CRD) with 5 treatments and 4 replicates. The treatments tested were levels of commercial feed replacement with FPK, namely: P0 (100% Commercial Feed), P1 (95% Commercial Feed + 5% FPK), P2 (90% Commercial Feed + 10% BISF), P3 (85% Commercial Feed + 15% BISF), and P4 (80% Commercial Feed + 20% BISF). The parameters observed included feed intake, body weight gain, and feed conversion ratio. Data were analyzed using analysis of variance. The results showed that the use of BISF to partially replace commercial rations did not affect (P>0.05) feed consumption, body weight gain, and feed conversion in broilers. It was concluded that BISF administration up to 20% can partially replace commercial rations without affecting broiler body weight gain.

Abstract

Sweet potatoes (Ipomoea batatas L.) are an important source of carbohydrates in Indonesia’s food diversification program. Sweet potato production declined from 2020 to 2021, in line with a decrease in harvested area. One effort to increase the productivity of this crop is through optimal planting distance and the use of biofertilizers containing bacteria that play a role in decomposing organic matter and providing nutrients for the plants. This study aims to determine the effect of the combination of planting distance and biofertilizer application frequency on the growth and yield of sweet potato plants. The study was conducted experimentally using a Completely Randomized Design (CRD) with six treatment combinations of planting distances (75 x 20 cm, 25 cm, and 30 cm) and biofertilizer application frequencies (3 and 4 times), each at 10 ml, with three replications. Analysis results showed that a planting distance of 75 x 30 cm with 3 or 4 applications of biofertilizer optimally increased the number of branches, fresh canopy weight, number and diameter of tubers, and the sweet potato harvest index.

Abstract

Water balance analysis is one approach in evaluating the balance between water avaibility and water need in rice fields in an irrigation area. This study aims to determine the avaibility of irrigation Area, carawali Village, Watang Pulu District, which is the area with the largest rice field are in the region, and took place from Febrary to June 2025. The method used is a quantitive mothed, with several analytical approaches, including analysis of the mainstay discharge with the Weibull approach, calculation of water needs using the Penman Modification FAO method, water balance analysis with a water balance approach, and evaluation of irrigation netwotk afficiency using Microsft Excel. The data used consist of irrigation discharge data, rainfall, climatology, cropping patterns, and irrigation network schemes for the period 2017-2024. The results of the study showed thet water surplus condition occurred in the November-Januari (II) and April-June (II) periods, while water deficits occurred in February-April (I) and July-October (II) which reflects the inability of water avaibility to meet needs due to low rainfall and irrigation discharage.

Abstract

Wheat imports are increasing due to the demand for wheat consumption, especially processed wheat, but not balanced by the production of wheat seed raw materials. To overcome this problem, it is necessary to assemble New Superior Varieties of wheat that are adaptive to Indonesian environmental conditions. This VUB assembly begins with the formation of an initial population conventionally, one of which can be through the use of chemical mutagens, namely colchicine. This study aims to obtain an effective colchicine concentration in increasing genetic variation, increasing genetic variation in the initial population of M0 wheat mutants, obtaining morphophysiological characters that have high coefficients of diversity, and obtaining M1 wheat seeds as candidates for the next generation. This research method begins with the selection stage of wheat parent seeds from several wheat varieties based on the physical aspects of the seeds and the characteristics of the yield components, soaking the sprouts using a colchicine mutagen solution, and planting the sprouts from the selected wheat parent seeds using a randomized block design consisting of five colchicine mutagen soaking treatments, namely without soaking; 400 ppm colchicine soaking; 600 ppm colchicine soaking; 800 ppm colchicine soaking; and 1000 ppm colchicine soaking. Each treatment was repeated three times. The results showed that 400 ppm of colchicine mutagen was an effective and dominant concentration for increasing genetic variation based on growth percentage, plant height, leaf number, and leaf length. The use of colchicine mutagens increased genetic variation due to its polyploidy properties, which are determined by the number of stomata formed.

Abstract

Red betel (Piper crocatum Ruiz & Pav.) can be propagated using stem cuttings, but cutting success is affected by planting media and phytohormone application. This study aimed to determine the effects of planting media composition and natural phytohormone type on the growth of red betel stem cuttings. The experiment was arranged in a randomized block design with two factors. The first factor was planting media composition, consisting of husk charcoal and sand at ratios of 1:1, 1:2, and 2:1. The second factor was phytohormone type, consisting of a control, shallot extract, aloe vera extract, and bean sprout extract. The observed variables were cutting success percentage, days to shoot emergence, plant length, shoot length, root length, and number of leaves. The results showed that the interaction between planting media composition and phytohormone type had no significant effect on all observed variables. However, the husk charcoal and sand medium at a ratio of 2:1 tended to produce better growth, with cutting success reaching 100% in several phytohormone treatments, root length reaching 7.00 cm, plant length reaching 18.53 cm, and shoot emergence occurring as early as 32 days after planting. Among the phytohormones, aloe vera extract tended to improve cutting success, shoot length, and number of leaves compared with the other treatments. These findings indicate that a planting medium with a higher proportion of husk charcoal, combined with natural phytohormones, particularly aloe vera extract, has potential to support the early growth of red betel stem cuttings.
