Abstract

Durian (Durio zibethinus Murr.) is a tropical fruit commodity with high economic value and increasing market demand. However, increasing durian production in Indonesia still faces obstacles, particularly the limited availability of high-quality seedlings. Data from the Sijunjung Regency Central Statistics Agency (2024) shows that durian production fluctuates, namely 31,043 tons in 2022, increasing to 36,107 tons in 2023, then decreasing to 34,177.40 tons in 2024. This condition indicates the need for improvements in cultivation technology, especially in the seedling supply stage. Vegetative propagation through grafting techniques using the cleft grafting method is an effective alternative because it can produce uniform seedlings and accelerate the fruiting period. The success of grafting can be improved through the use of natural organic growth regulators (ZPT), such as coconut water, shallot extract, bean sprout extract, and bamboo shoot extract. This study aims to determine the effect of various types and doses of organic ZPT on the success and growth of durian grafting and to determine the best ZPT. The study used a randomized block design with five treatments and five replicates. The treatments consisted of a control without PGR, 250 ml/plant of red onion extract, 200 ml/plant of bean sprout extract, 250 ml/plant of coconut water, and 250 ml/plant of bamboo shoot extract. The data were analyzed using ANOVA, and if there were significant differences, they were followed up with Duncan's multiple range test at a 5% level. The results showed that all treatments produced a 100% survival rate. Organic PGRs had a significant effect on the number of leaves and upper stem diameter, but no significant effect on the increase in shoot length and lower stem diameter. Bean sprout extract produced the highest number of leaves, while coconut water produced the largest upper stem diameter. Keywords: cuttings, durian, growth regulators, organic plant, seeds, slits

Abstract

Cocoa  (Theobroma  cacao  L.)  is  a  plantation  crop  of  high  economic  value  that  requires  high-quality  seedlings  to  support  optimal  field  productivity.  One  of  the  main  constraints  in  cocoa  nurseries,  particularly  for  the  Trinitario  variety  in  Jorong  Kampung  Juar,  Nagari  Tanjung,  is  the  use  of  planting  media  derived  from  burned  soil,  which  is  generally  low  in  nutrients  and  may  contain  potentially  toxic  compounds.  Cocopeat,  a  by-product  of  coconut  husk  processing,  has  potential  as  an  alternative  growing  medium  due  to  its  physical  properties,  including  high  water-holding  capacity,  improved  aeration,  and  a  pH  suitable  for  cocoa  growth.  This  study  aimed  to  evaluate  the  effects  of  different  cocopeat-based  growing  media  compositions  on  the  growth  of  cocoa  seedlings  and  to  assess  their  suitability  as  an  alternative  nursery  medium.  The  study  employed  a  Completely  Randomized  Design  (CRD)  with  four  treatments  and  five  replications.  The  treatments  consisted  of  soil  and  goat  manure  as  the  control,  and  three  cocopeat  application  rates  of  450  g,  550  g,  and  650  g  per  polybag.  Observed  parameters  included  plant  height,  number  of  leaves,  stem  diameter,  growing  media  temperature,  growing  media  pH,  leaf  color,  and  plant  survival  percentage.  Data  were  analyzed  using  analysis  of  variance  (ANOVA),  and  the  coefficient  of  variation  was  used  to  evaluate  data  homogeneity  and  experimental  precision.  The  results  showed  that  the  application  of  cocopeat  at  different  rates  did  not  significantly  affect  any  of  the  observed  growth  parameters  of  cocoa  seedlings.  Nevertheless,  a  positive  growth  trend  was  observed  in  several  vegetative  parameters  in  treatments  containing  cocopeat,  particularly  in  maintaining  stable  moisture,  temperature,  and  pH  of  the  growing  media.  The  low  coefficients  of  variation  across  most  parameters  indicated  that  the  data  were  homogeneous  and  the  experiment  had  a  high  level  of  reliability.  All  treatments  resulted  in  a  100%  survival  rate,  indicating  that  cocopeat-based  growing  media  are  safe  and  suitable  for  cocoa  seedling  production.  Therefore,  cocopeat  can  be  used  as  an  alternative  growing  medium  for  cocoa  nurseries,  although  adjustments  in  composition  are  necessary  to  optimize  its  benefits  under  local  condition. Keywords:  cocoa  seedlings,  cocopeat, cocoa, vegetative

The experiment was used Complete Randomized Block Design (CRBD) with two treatment factors namely; POC Jakaba (J0 = without POC, J1 = 250 ml/polybag, J2 = 500 ml/polybag, J3 = 750 ml/polybag) and chicken manure POP (A0= without POP, A1=500 g/polybag, A2 = 1000 g/polybag, A3 = 1500 g/polybag), with three replications, resulting in a total of 48 plots. The parameters were measured plant length, stem diameter, fruit length and diameter, and fruit weight per sample and per plot. The results were showed that Jakaba POC had a significantly effect on plant length, stem diameter, and fruit weight/plot, respectively. For chicken fesses POP, there was no significantly effect on the parameters of stem diameter, fruit length, and fruit diameter, but a significant effect on the parameters of plant length, fruit weight/sample, and fruit weight/plot. The interaction between Jakaba POC and chicken fesses POP had no significantly effect on all parameters. It can be concluded that the chicken fesses POP was good at a dose of 1000 grams/polybag as compared to other treatments. While Jakaba POC was better at 500 mL/polybag. Keywords: Jakaba POC, chicken manure POP, growth, yield, timun suri

Abstract

Scallions are high-value economic crop that contains essential nutrients and minerals that support health. This study aimed to determine the effect of various concentrations of liquid organic fertilizer derived from goat urine on the growth and yield of scallions. The research was conducted in Tongko Village, Baroko Subdistrict, Enrekang Regency, from April to July 2025. The Complete Randomized Block Design (CRBD) Single-Factor method was applied in this study, using five different treatments and six replicates. The concentrations of liquid organic fertilizer tested include 0% (0 ml.l-1), 2.5% (25 ml.l-1), 5% (50 ml.l-1), 7.5% (75 ml.l-1), and 10% (100 ml.l-1). The data obtained were analyzed using analysis of variance, followed by the Least Significant Difference test at α 5% significance level. The results showed that applying liquid organic fertilizer derived from goat urine did not affect scallion plant height and leaf number. However, it substantially impacts the fresh and economic weight of the plants, with a concentration 10% (100 ml.l-1) being the best for enhancing the growth and yield of scallions. Further research is recommended to test higher concentrations to achieve maximum scallion growth and yield under field conditions.Keywords: concentrations, goat urine, liquid organic fertilizer, scallion

Abstract

The use of livestock waste as liquid organic fertilizer (LOF) is a sustainable solution for reducing dependence on chemical fertilizers and improving environmental quality. Goat manure has potential as a raw material for LOF because it contains the macronutrients nitrogen (N), phosphorus (P), and potassium (K), as well as microorganisms that play a role in the decomposition process. This study aims to analyze the dynamics of the microbial population (bacteria and fungi), changes in NPK nutrient content, and environmental conditions during the fermentation of goat manure POC. The study was conducted over 21 days at the Biology Laboratory of the Department of Agroindustry, University of Padang, using a completely randomized design with eight fermentation time points and three replicates. Microbial populations were analyzed using the Total Plate Count (TPC) method, while NPK content was measured using a Rapid NPK tester. Data were analyzed using ANOVA and the DMRT post-hoc test at the 5% level. The results showed that fermentation duration had a highly significant effect on microbial population and nutrient content. Bacterial population peaked on day 18, while fungal population was highest on day 15 of fermentation. The highest nitrogen content was obtained on day 21, while phosphorus and potassium were highest from days 18 to 21. The pH value remained relatively stable within the neutral range, and the temperature remained within the mesophilic range, which supports microbial activity. It was concluded that fermentation for 18–21 days produced POC with optimal biological and chemical quality and has the potential to be used as an environmentally friendly liquid organic fertilizer. Keywords: liquid organic fertilizer, goat manure, fermentation, microorganisms, NPK

Abstract

Pakcoy (Brassica rapa L.) is a leafy vegetable with high nutritional value widely consumed in Indonesia. However, its productivity in the field is often limited by inadequate macro and micronutrient availability in the soil. Balanced fertilization using both organic and inorganic sources is crucial to support optimal growth and yield. This study aimed to determine the effects of chicken manure and NPK 20-20-20 fertilizer, both individually and in combination, on the growth and yield of pakcoy plants. The research was conducted over two months (June–August) at the experimental field of the University of Community Development using a factorial Randomized Complete Block Design (RCBD) with two factors: chicken manure (0, 1, 2, and 3 kg/plot) and NPK 20-20-20 fertilizer (0, 15, 20, and 25 g/plot), each with three replications. Observed parameters included plant height, number of leaves, shoot fresh weight, and root length. The results showed that chicken manure significantly affected plant height (weeks 1 and 4) and shoot fresh weight. The K2 treatment (2 kg/plot) produced the highest results with a plant height of 41.2 cm and a fresh weight of 118.1 g. NPK fertilizer alone had limited effect, but N1 (15 g/plot) yielded the longest root (28.9 cm) and the highest shoot fresh weight (128.5 g). The interaction between the two fertilizers was significant, with the K2N1 combination producing the highest shoot weight (203.0 g), and K1N1 yielding the longest root (40.1 cm). In conclusion, the combination of 2 kg/plot chicken manure and 15 g/plot NPK fertilizer is the most effective treatment to enhance pakcoy growth and yield. Moderate doses of organic and inorganic fertilizers are proven to support sustainable pakcoy cultivation. Keywords: chicken manure, growth, NPK 20-20-20, pakcoy, yield
