Abstract

The problem of good plant nutrition is still a question mark, the use of fertilizer and PGPR can increase plant growth and yield. This study aims to determine the effect and interaction of seed soaking using PGPR and chicken manure doses on the growth and yield of cucumbers. This study was carried out on land owned by residents in Tambun Village, Tolitoli Regency, Central Sulawesi Province, using a Randomized Block Design (RAK) factorial treatment, namely the first factor of seed soaking consisting of 3 levels, namely: W0 (control), W1 (4 hours), W2 (6 hours). The second factor, the dose of chicken manure consisting of 3 levels, namely: D0 (control), D1 (3 kg), D2 (4 kg). Each treatment was repeated 3 times so that there were 27 beds in total, each bed consisting of 4 sample plants, so that the total number of plants was 108 plants. The results showed that soaking cucumber seeds using PGPR could increase growth well with a soaking time of 6 hours including: plant height, number of leaves, number of segments. In the generative phase, soaking seeds using PGPR can increase growth by observing the number of flowers. The treatment of chicken manure doses has an effect on plant growth and yield in the 4 kg treatment including: plant height, number of leaves, number of internodes, and number of flowers. The best combination of treatment on the growth of cucumber seeds soaking using PGPR and chicken manure doses is in the W2D2 treatment, namely 6 hours of seed soaking and 4 kg of fertilizer dose. Soaking seeds with a combination of chicken manure can increase vegetative and generative plant growth.

Abstract

This study aimed to determine the effect of chicken manure bokashi and NPK Phonska fertilizer on the growth and yield of sweet corn (Zea Mays saccaharate sturt). The research was conducted at the Experimental Farm of the Faculty of Agriculture, Madako University Tolitoli, from March to May 2025, using a factorial Randomized Complete Block Design (RCBD) with two treatment factors. The first factor was the dosage of chicken manure bokashi (B), consisting of B0 = without bokashi, B1 = 5 tons/ha (1 kg/plot), and B2 = 10 tons/ha (2 kg/plot). The second factor was the dosage of NPK Phonska fertilizer (N), consisting of N0 = without NPK, N1 = (80 g/plot or equivalent to 6 g/plant), and N2 = (140 g/plot or equivalent to 11 g/plant). Each treatment combination was replicated three times, resulting in 27 experimental plots. The results showed a significant interaction between chicken manure bokashi and NPK Phonska fertilizer on plant height, number of leaves, fresh cob weight, cob weight with husk, cob length, and number of kernels per row. The best combination was obtained with B2N2 (bokashi 10 tons/ha and NPK Phonska 700 kg/ha), producing a plant height of 166.06 cm, 7.00 leaves, fresh cob weight of 398.06 g, cob weight with husk of 567.78 g, cob length of 22.00 cm, and 40.61 kernels per row.

Abstract

This study aimed to evaluate the effect of the interaction between NPK Mutiara fertiliser dosage and branch pruning on the growth and yield of tomato plants (Lycopersicum esculentum Mill.). The experiment was carried out from March to May 2024 at the experimental field of the Faculty of Agriculture, Madako University, Tolitoli, Tambun Village, Baolan District, Tolitoli Regency. A factorial Randomised Block Design (RBD) was used with two factors: NPK Mutiara fertiliser dosage (0 g/plant, 15 g/plant, and 25 g/plant) and branch pruning (no pruning, leaving three main branches, and leaving four main branches). Each treatment combination was replicated three times, resulting in 27 experimental units. The results revealed a significant interaction between NPK Mutiara fertiliser and branch pruning on plant height (51.92 cm) and fruit weight per sample (391.50 g). The single factor of branch pruning had a highly significant effect on fruit diameter at 67 days after planting (48.47 mm) and 74 days after planting (57.86 mm), with the best performance observed in treatments leaving 3–4 main branches. Overall, applying NPK Mutiara fertiliser at 25 g/plant combined with pruning to 3–4 main branches enhanced the growth and yield of tomato plants.

Abstract

Shallots (Allium ascalonicum L.) are one of the important horticultural commodities in Indonesia whose productivity is greatly influenced by cultivation techniques, especially mulch and organic fertilizer. This study was conducted to increase the growth and yield of shallots through various types of mulch and doses of chicken manure. The study was conducted in the Faculty of Agriculture practice field, Madako University, Tolitoli, Tolitoli Regency, Central Sulawesi, for three months, from February to April 2024. The design used was a two-factor Randomized Block Design (RBD), namely the type of mulch (M0: without mulch, M1: rice husk charcoal, M2: plastic mulch) and the dose of chicken manure (K0: without fertilizer, K1: 10 tons/ha, K2: 20 tons/ha), each with three replications. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that the plastic mulch treatment (M2) significantly affected the fresh weight of tubers with leaves, the fresh weight of tubers without leaves, and the number of tubers. Meanwhile, a dose of 20 tons/ha of chicken manure (K2) significantly affected the fresh weight of tubers both with and without leaves. The interaction between the two factors was insignificant, so their effects were independent. Thus, increasing the dose of chicken manure (K2) still produced the highest yield regardless of the type of mulch used.

Abstract

This community service activity was carried out in Kabinuang Village, Dampal Utara District, as an effort to address the issue of underutilized vacant land around residents' gardens. Unused land that is not productively managed has the potential to become idle land, contributing neither to food security nor to the economic improvement of the community. This activity aimed to provide education, training, and assistance to the community in managing vacant land into productive areas through the cultivation of horticultural crops and medicinal plants. The methods used included initial observation, socialization, basic cultivation technique training, and monitoring of the activity outcomes. The results of the service showed an increase in community knowledge and skills in utilizing vacant land, as well as the establishment of several productive garden plots as pilot examples in the village. This initiative is expected to serve as an initial step toward the sustainable use of land to support local food security and improve the welfare of the people of Kabinuang Village.

Abstract

Bambapula Village is a coastal area with an abundant number of coconut trees, resulting in a large amount of coconut fiber waste. The use of this waste is still very limited, generally only sold at low prices or burned, which causes negative impacts in the form of air pollution and health problems. In fact, coconut fiber has the potential to be processed into alternative planting media, especially in dry land conditions in coastal areas. This service activity aims to improve the knowledge and skills of PKK women and coconut farmers in utilizing coconut fiber waste productively. The method used is Asset Based Community Development (ABCD), with an emphasis on the utilization of available local assets. Activities include socialization, technical training on making planting media from coconut fibers, and assistance in sustainable waste management management. The results of the activity show that the community is able to understand and practice coconut fiber processing techniques as a planting medium, as well as gain insight into the added value of the economy and its ecological benefits. Thus, this activity contributes to the empowerment of coastal communities through the use of integrated, sustainable, and economically valuable coconut waste.
