Abstract

Bayam brazil merupakan sayur bergizi tinggi dan sangat potensial dikembangkan dalam program Rumah Pangan Lestari (RPL). Pengembangannya secara berkelanjutan dan ramah lingkungan, seperti pupuk organik sebagai sumber unsur hara masih membutuhkan banyak kajian. Penelitian ini bertujuan untuk mempelajari pertumbuhan dan hasil tanaman bayam brazil akibat perlakuan berbagai jenis pupuk organik padat dan pupuk organik cair (POC) serta kombinasinya. Metode eksperimental digunakan dengan perlakuan-perlakuan sebagai berikut: (A) pupuk anorganik NPK (16-16-16) sebagai pembanding, (B) pupuk organik kotoran ayam , (C) pupuk organik kotoran sapi, (D) pupuk organik bekas cacing, (E) pupuk organik kotoran ayam dengan POC Nasa, (F) pupuk organik kotoran sapi dengan POC Nasa, dan (G) pupuk organik bekas cacing dengan POC Nasa (G). Percobaan dirancang menggunakan rancangan acak lengkap non-faktorial dengan empat ulangan. Hasil penelitian menunjukkan bahwa pupuk organik padat atau kombinasi pupuk padat organik dengan POC berpengaruh secara nyata terhadap diameter batang dan total hasil pada umur 35 hari setelah tanam. Total berat basah dan berat konsumsi per tanaman tertinggi dihasilkan oleh perlakuan B, yaitu secara berturut-turut 90,1 g dan 58,9 g per tanaman. Hasil dari perlakuan B lebih rendah dari hasil perlakuan A, namun berbeda secara tidak nyata. Pupuk organik kotoran ayam dapat digunakan sebagai sumber unsur dalam pengembangan tanaman bayam brazil dalam skala rumah tangga.

Abstract

This study aimed to determine the appropriate weeding time and its effect on growth and yield on several generations of mung bean seeds (Vigna radiata L.) planted in a dry land. A field trial was conducted from September to November 2018 in the hamlet of Amor-amor, Gumantar Village, Kayangan District, North Lombok Regency. The weeding times tested were: 2 weeks after planting, 4 weeks after planting and without weeding. Meanwhile, the seed generation factors were: foundation seeds, the first-generation of extension seeds and the second-generation of extension seeds. All the treatments were arranged factorially using a Randomized Block Design with 3 replications. The results showed that there was no interaction between weeding time and seed generation in affecting plant growth, but weeding time and seed generation affected crop yields. The highest yield of mung bean seeds was obtained from weeding treatment at 2 weeks after planting, while the seed generation that gave the highest yield was the second extension seeds. To grow mung beans of Vima-1 variety in dry lands, it is recommended to do weeding at 2 weeks after planting and to use the second generation of extension seeds.

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

Abstract

The use of inorganic fertilizers in high doses for chili pepper (Capsicum frutescens L.) cultivation can negatively impact plant productivity over time. This study aimed to evaluate the effectiveness of chicken manure (CM) and foliar fertilizer (FF) in reducing the reliance on inorganic fertilizers for chili pepper plants grown in dryland conditions. The experiment was conducted in Gumantar Village, North Lombok Regency, from March to August 2023. As the control, an inorganic fertilizer treatment with NPK (16-16-16) at a dose of 1,200 kg/ha was used. The tested treatments included 85% NPK + CM, 70% NPK + CM, 55% NPK + CM, 85% NPK + CM + FF, 70% NPK + CM + FF, and 55% NPK + CM + FF. The dose of chicken manure applied was 20 tons/ha. These treatments were arranged using a randomized block design with three replications. The results indicated that CM, with or without FF, could increase the percentage of flowers that developed into fruits. There were no significant differences in the growth and yield of chili plants among the various treatments, suggesting that CM, with or without FF, could effectively replace up to 45% of the inorganic fertilizers used. This finding indicates that the dependence on inorganic fertilizers in chili pepper cultivation in drylands can be gradually reduced by incorporating organic and foliar fertilizers

Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the horticultural commodities that needed throughout the year. In certain season, such as the rainy season, production tends to be low due to the low yield of chilies. Therefore, it is important to get the cultivation technology of cayenne pepper outside the season. This research aimed to study growth and yield of two varieties of cayenne pepper grown off-season treated with different concentrations of POMI foliar fertilizer. One experiment was carried out in October 2020 to March 2021 in a dryland of Gumantar Village, Kayangan District, North Lombok Regency. The factors tested were varieties (Sret and Taruna) and POMI foliar fertilizer concentrations (0%, 1.0% and 1.5%). The treatments were arranged using a factorial randomized block design (RBD) with three replications. The results showed that the variety and concentration of POMI leaf fertilizer interacted in affecting the number of flowers and the number of fruits. The highest number of flowers and fruit was produced by Taruna variety which was treated with POMI foliar fertilizer at 1.5% concentration. Taruna variety showed a better growth and yield than Sret while the concentration of POMI foliar fertilizer which produced the best growth and yield was 1.5%. To get high yields in off-season chili cultivation, it is recommended to grow Taruna varieties and be treated with POMI foliar fertilizer with a concentration of 1.5%.

Abstract

Cayenne pepper is one of the horticultural commodities that its production is low in the rainy season (off-season) due to the high potential for flower abortion and plant disease attacks. This study aimed to determine the effect of manure plus and varieties on the growth and yield of some cayenne pepper varieties planted off- season. The experiment was carried out in the 2020/2021 rainy season in Gumantar Village, Kayangan District, North Lombok Regency. The treatments were arranged using a Split Plot design with three replications. The main plot was manure treatment with 2 treatment levels, with and without manure plus, while as sub-plots were varieties, Taruna, Sret and Mutiara Bumi. The results showed that plant height and number of leaves at the age of 56 DAP and 98 DAP were significantly affected by manure plus treatment, and by variety too. The effect of varietal treatment showed significantly different on yield variables, such as fruit weight per plant and fruit weight per plot. The highest yield was shown by Taruna variety while Sret and Mutiara Bumi varieties did not show different results. There was an interaction between the treatment of manure and variety on the variable number of flowers, number of fruits and percentage of flower abortion. The best interaction effect occurred in the treatment of Taruna variety treated with manure plus. From the results of this study, it can be suggested to grow Taruna variety treated with manure plus to obtain high yields of cayenne pepper grown off-season on drylands.

Abstract

Gumantar Village is in North Lombok Regency, West Nusa Tenggara. This village is classified as a developing village with many problems, including stunting. Stunting is caused by mothers and children's lack of adequate nutrition and nutrients, which impacts children's physical and mental growth as the nation's golden generation. Therefore, it is vital to prevent stunting in Gumantar Village, considering the village is the frontline in eradicating stunting. To prevent stunting, the KKN-PMD group of Mataram University initiated the utilization of white Jack bean (Canavalia ensiformis) as a raw material for making tempeh to replace soybeans to increase nutritious food and the economy in Gumantar Village. The activity was carried out from December 2023 to January 2024. This tempeh-making aimed to fulfill the community's nutritional intake through tempeh, which is rich in properties and nutrients and can become a community income to improve the economy. The method used through the work program to reduce stunting rates in Gumantar Village was healthy village socialization on stunting prevention, a stunting campaign through Posyandu, and nutritious food demonstrations to make tempeh from white Jack beans. Other activities carried out to prevent stunting were sexual education to children and socialization of early marriage to adolescents who are experiencing the puberty phase. The results of the socialization activities and demonstrations of processing white Jack beans as a primary ingredient for making tempeh were that the community had a better understanding of how to prevent stunting and how to make tempeh from white Jack beans—most of the community members like the tempeh both in terms of taste, shape, and texture. Participants well accepted sexual education and early marriage socialization.

Abstract

The quality of coffee, including taste and aroma, is determined mainly by the timeliness of harvesting and post-harvest processes. The quality of Robusta coffee produced in Tenggorong Hamlet, Gumantar Village, North Lombok Regency is still relatively low because the harvesting of coffee beans is carried out using the strip picking method and not the selective picking method. The post-harvest method is still inappropriate, especially in the section for producing green beans. This extension aimed to improve the quality of Gumantar Village coffee through activities to increase farmers' knowledge and capacity in conducting harvest and post-harvest processes. Marketing facilitation activities were also carried out using various applicable process standards. The results and evaluation of the activities showed an increase in coffee farmers' knowledge and capacity in selective picking and post-harvest coffee processing. Coffee processing methods that determine the taste, such as green bean preparation and roasting, have also been well understood. The facilitation has resulted in a business identification number (NIB), label and packaging logo with 'Sangakopi' product brand rights, halal certificate, and distribution permit. It is expected that 'Sangakopi' products will enter the NTB Mall shortly.

Abstract

Maize and mungbean are two common crops grown in dryland areas with sandy soil structures. This study aimed to explore the potential of adding cayenne pepper to increase crop diversity using strip intercropping (SI) as a potential system to improve farmers' return. There were seven treatments tested: monoculture maize, monoculture mungbean, monoculture cayenne pepper, SI maize and mungbean, SI maize and cayenne pepper, SI mungbean and cayenne pepper, and SI maize, mungbean, and cayenne pepper. The size of the treatment plot was 700 cm × 500 cm, and all the treatments were arranged in a Randomized Block Design with three replications. The study showed no difference in the land equivalent ratio (LER) for all the SI treatments, with a value of around 1.0. This indicates no advantage of SI over monocropping in terms of land usage. However, when the market prices valued the yield of each component crop in SI at harvest, the highest economic value came from monocrop cayenne pepper treatment (IDR 246 million ha-1). All the SI treatments involving cayenne pepper resulted in a higher return than the monoculture of maize or mungbean. The lowest economic value was shown by monoculture mungbean treatment (IDR 33.1 million ha-1). These results indicate that diversifying crops can improve farmers' return, especially by incorporating cayenne pepper in dryland with sandy soil.
