Abstract

Gibberellin (GA₃) is a growth hormone that is essential in plant physiological processes. At present, gibberellins are employed in commerce to enhance the physical traits and yield of various vegetable, horticultural, ornamental, and medicinal crops. This research aimed to study the effects of gibberellin application on the morphological characteristics and yield of lettuce plants. The study was arranged in a Completely Randomized Design (CRD) with six treatments of gibberellins concentration with a hydroponic system, namely: G0 = control, G1 = 20 ppm, G2 = 40 ppm, G3 = 60 ppm, G4 = 80 ppm, and G5 = 100 ppm, and each treatment consisted of four replications. This research was conducted in May–July 2023 at the Kemuning Greenhouse, Belu Regency, East Nusa Tenggara. GA₃s were sprayed twice at 2 weeks after sowing and 1 week after transplanting. The results showed that the highest GA₃ concentration (100 ppm) had a negative impact on plant morphology and yield, producing the smallest number of leaves, too long stem, pale green leaves, and the lowest fresh weight. Meanwhile, GA₃ concentration of 40 ppm resulted in the highest number of leaves. However, this increase is not directly proportional to the fresh weight of the leaves. GA₃ concentration of 40 ppm resulted in the best and most efficient yield of leaves and fresh weight, making it highly recommended.

Abstract

Mangrove planting and coastal clean-up activities at Sukaer Laran Beach, Kenebibi Village, Belu Regency, East Nusa Tenggara, were carried out with the aim of rehabilitating coastal ecosystems and raising public awareness of the importance of environmental conservation. The activity involved lecturers and 25 cadet students from the Military Logistics Vocational Faculty (FVLM), Plantation Crop Cultivation Study Program, in collaboration with KPP Pratama Atambua. The program employed an andragogical approach, incorporating discussion and service learning methods, including a public outreach session on the importance of mangroves and coastal conservation, symbolic distribution of mangrove seedlings, planting activities, and a collective beach clean-up. The results showed increased community participation and successful rehabilitation of the coastal area through mangrove planting and waste reduction. This activity had a positive impact on coastal environmental sustainability and strengthened the role of local communities in preserving coastal ecosystems. Therefore, similar programs should continue to be supported to maintain environmental sustainability in East Nusa Tenggara's coastal regions.

Abstract

Soil tillage and the application of organic materials such as boiler ash play a crucial role in improving soil fertility and crop productivity. This study aimed to evaluate the effects of different tillage systems and boiler ash application on the growth and yield of sugarcane (Saccharum officinarum). The experiment was arranged in a randomized complete block design (RCBD) with five treatments and three replications, involving tillage variations (plowing, harrowing, subsoiling) and 40 tons ha⁻¹ of boiler ash. Data were analyzed using the LSD test at a 5% significance level. The results showed that treatment P5 produced the best growth performance, with a plant height of 2.85 cm, stem diameter of 2.33 cm, and 15 tillers at 9 weeks after planting. This treatment also achieved the highest yield of 122.79 tons ha⁻¹, with a 7.18% increase in productivity. Positive correlations were observed between yield and plant height (R² = 0.4593) as well as stem diameter (R² = 0.793). These findings suggest that the appropriate combination of tillage techniques and boiler ash application has the potential to sustainably enhance sugarcane productivity.

Abstract

South Lamaknen District is the center of coffee production in Belu Regency. Coffee production is influenced by external and internal factors, H. vastatrix attacks are among the main external factors that limit coffee production in this district. Data information related to leaf rust disease in Belu district does not yet exist. Data on the distribution and severity of coffee leaf rust disease in this district do not yet exist. Such data is needed to determine appropriate control strategies to improve coffee production. The study aimed to obtain data on the severity of coffee leaf rust disease in smallholder coffee plantations in Belu Regency. The research method used was purposive random sampling (PRS) in the Belu people's coffee center in Lakmaras and Henes Villages, South Lamaknen District, with a geographical location between 9 ْ0.9' 26.61"N and 125 ْ 09' 50" LS, at an altitude between 866,7 – 1007,7 m above sea level. This study shows that coffee leaf rust disease is spread in geographical locations 9 ْ 0.9' 26.61"N and 125 ْ 09' 50" LS. The highest intensity of coffee leaf rust disease occurred in Henes village, which was 39%, while Lakmaras village was 22%. External factors affecting the incidence and severity of disease are temperature and use distance between coffee plants.
