Abstract

This research aims to determine the effect of the combination of silica and paklobutrazaol on increasing cayenne pepper production. The research was conducted in North Lombok at an altitude of 300 m above sea level with dry, sandy soil conditions. The research was carried out for 7 months, from May to October 2023. The materials used were free-pollen cayenne pepper of the CBR 25 variety, liquid silica, and paclobutrazole. The research design used was a factorial randomized block design (RAK). The first factor is paclobutrazol, which consists of 3 levels of treatment: without paklobutrazol, paclobutrazol 250 ppm, and paclobutrazol 500 ppm. The second factor is silica with two levels, namely without silica and 2 ml/L silica. The results showed that silica application resulted in growth that was not significantly different in plant height, diameter, and canopy width but significantly different in the percentage of flower fall and fruit set per plant. Plants applied with silica gave a smaller percentage of flower fall than without silica at 12.17%, and fruit weight per plant was heavier at 182.75 gr/plant. Giving paclobutrazol to plants gave significantly different results in plant height, stem diameter, crown width, number of flowers, percentage of flower drop, number of fruit, and fruit weight per plant. From the results, it can be seen that the treatment with 500 ppm paclobutrazol gave the highest number of flowers, number of fruits, and fruit weight compared to other treatments. The interaction between silica and paclobutrazol gave results that were not significantly different except for plant height.

Abstract

Cocoa (Theobroma cacao L.) is an economically valuable crop, especially in the chocolate industry. However, cocoa seedling productivity in Indonesia faces challenges such as low-quality seedlings and suboptimal cultivation practices. This study aimed to evaluate the effect of cow manure on the growth of cocoa seedlings from smallholder farms in North Lombok, focusing on its potential as a sustainable nursery management practice. The experiment was conducted using a randomized complete block design with five treatments involving different ratios of cow manure and standard nursery media (topsoil and sand). Seedling growth parameters such as germination rate, seedling height, stem diameter, leaf number, and biomass accumulation were measured at 30, 60, and 90 days after planting. The results showed significant improvements in all growth parameters with the application of cow manure compared to the control. The best performance was observed at 300 g of cow manure per polybag, resulting in a maximum seedling height of 35.2 cm, 14.2 leaves per seedling, and a dry biomass of 34.7 g. The cow manure enhanced soil fertility, improved water retention, and supported microbial activity, contributing to better seedling vigor. In conclusion, cow manure is a viable organic amendment for cocoa seedling production, especially in resource-constrained farming systems

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh berbagai konsentrasi POC GDM terhadap pertumbuhan dan hasil jamur tiram coklat. Percobaan dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) dengan lima perlakuan konsentrasi POC GDM (0, 10, 20, 30, dan 40 ml/liter air) dalam lima blok dengan sepuluh ulangan. Total 250 baglog jamur digunakan dengan sistem tanam gantung. Aplikasi pupuk dilakukan sekali per pekan (20 ml/baglog) selama dua bulan penelitian (September-Oktober 2024) di Desa Sukadana, Lombok Tengah. Parameter yang diamati meliputi panjang tangkai, lebar tudung buah, jumlah kuntum, jumlah badan buah, dan berat basah. Analisis data dilakukan dengan metode ANOVA pada tingkat signifikansi 5%. Hasil penelitian menunjukkan konsentrasi POC GDM tidak memberikan pengaruh signifikan terhadap semua parameter. Meskipun demikian, konsentrasi 20 ml/liter air menunjukkan nilai tertinggi untuk jumlah badan buah (3,42) dan berat basah (34,17 gram), sementara konsentrasi yang lebih tinggi (30 ml/liter dan 40 ml/liter air) menunjukkan performa lebih baik pada parameter morfologi seperti panjang tangkai dan lebar tudung. Faktor lingkungan seperti kelembaban, suhu, dan intensitas cahaya, serta karakteristik media tanam diduga lebih berpengaruh terhadap pertumbuhan jamur tiram dibandingkan aplikasi POC GDM.

Abstract

Cashew tree plantations often experience fallow periods, causing the soil layer to be more easily eroded. As a result, the process of decreasing land productivity is happening more quickly. The right action to overcome this problem is to utilize the reciprocal relationship between plants and livestock to form an integrated ecological farming model. The purpose of this activity is to improve farmers' knowledge and skills in managing cashew nut plantations by implementing integrated ecological farming, processing agricultural waste, weeds and other forage for animal feed, and processing manure and livestock waste into organic fertilizer. The approach method used is participatory action in the form of direct training and assistance in the field from May 5, 2024 to November 6, 2024. The results of the activity showed that the implementation of training and mentoring for the application of integrated ecological farming models on cashew nut stands took place in an orderly, safe and smooth manner. The knowledge and skills of members of the Tunas Mekar farmer group, Lendang Mamben hamlet, Anyar Village, Bayan, North Lombok increased, as evidenced by their high participation, enthusiasm and enthusiasm in following the entire series of activities. The cultivation of peanuts and corn crops resulted in higher income and profits for farmers compared to the cultivation of long beans. In addition to being able to provide higher profits, the average BC-ratio for cultivating these two types of crops is also relatively higher compared to cultivating long beans, namely 2.81 for corn and 2.67 for peanuts

Abstract

This Community Service activity was carried out in Labangkara, Sukadana Village, Bayan District, North Lombok Regency, from July to November 2024, in collaboration with the Padi Subur farmer group. Agriculture in this village is dominated by dry land with low productivity and crop diversification. Farmers face challenges in cultivation that is not yet intensive and reliance on chemical inputs such as inorganic fertilizers, pesticides, and herbicides, which increase production costs and cause environmental pollution, threatening agricultural sustainability. On the other hand, livestock waste (cattle and goats) in this village has not been utilized, causing environmental impacts such as unpleasant odors from ammonia and hydrogen sulfide gases, as well as health risks. The aim of this activity was to provide knowledge and skills to farmer group members on making compost from livestock waste, to support crop diversification and sustainable agriculture. The approach used was the participatory action method, involving the community fully from planning to evaluation. The results showed a significant increase in participants' understanding, seen from their ability to explain the steps of compost making after the training. Participants' enthusiasm and active participation, both in discussions and independent practice, were also very high, indicating their great interest in managing animal waste into useful compost. This success confirms the effectiveness of interactive and practical training methods, as well as demonstrative methods, in increasing knowledge and learning motivation.

Abstract

Drylands with limited resource support need to increase their productivity. One indicator of land productivity is the land equivalence ratio (LER). This research aimed to study the growth and yield of red chili due to the effect of varieties and peanut planting times in intercropping systems to increase dryland productivity. One experiment was conducted in Amor-amor Hamlet, Gumantar Village, Kayangan Sub-district, North Lombok Regency, from March to August 2023. The red chili varieties tested were Baja MC (hybrid) and Landung (non-hybrid). Meanwhile, peanut (Hypoma 2 variety) planting time was at the same time, one week after planting (WAP) of chili and 3 WAP. The treatments were arranged factorially using a Randomized Block Design with three replications. All component crops had monoculture treatments to calculate LER. The results showed no interaction between variety and planting time on all parameters observed. Variety had no significant effect on growth and LER but significantly affected the yield of chili. The Landung variety produced higher yields than the Baja MC variety. Planting time treatment had no significant effect on growth and LER but significantly affected the yield of chili. The planting time of peanut that produced the highest yield was 3 WAP. The intercropping of chili with peanuts at all planting times increased dryland productivity with LER values greater than 1.0
