Abstract

Petani jambu mete di dusun Renggorong, desa Sambik Elen, Bayan, Lombok Utara, kesulitan mendapatkan pupuk untuk memenuhi kebutuhan pemupukan tanaman jambu metenya. Akibatnya produksi nut mete rendah baik kuantitas maupun kualitas sehingga kurang diminanti oleh konsumen dan daya jualnya rendah. Solusi untuk mengatasi masalah itu adalah mencari sumber bahan pupuk alternatif, yaitu memanfaatkan kotoran hewan, limbah kandang ternak sapi dan limbah pertanian menjadi pupuk organik untuk menggantikan pemakaian pupuk an-organik yang harganya semakin mahal dan langka. Namun ada masalah yang harus diatasi, yaitu kurangnya pengetahuan dan keterampilan petani memproduksi pupuk organik. Selain itu kemampuan kewirausahaan dan wawasan agribisnis petani juga masih kurang. Karena masalah tersebut, maka telah dilaksanakan program penyuluhan yang bertujuan untuk meningkatkan pengetahuan dan keterampilan petani mengelola tanaman jambu metenya melalui aplikasi pupuk organik untuk menanggulangi kelangkaan dan mahalnya harga pupuk anorganik. Kegiatan penyuluhan berlangsung dengan tertib, aman dan lancar. Pengetahuan dan keterampilan petani untuk memproduksi pupuk organik meningkat, terbukti dari tingkat partisipasi dan antusiasme petani yang semula rendah setelah mengikuti penyuluhan dapat ditingkatkan menjadi tinggi. Aplikasi beberapa tindak agronomi secara intensif seperti aplikasi pupuk organik 15 - 20 ton ha-1 dan pupuk NPK Ponska 75 – 150 kg ha-1, memberikan hasil total bobot buah gelondong pohon-1 dan total bobot nut pohon-1 signifikan lebih tinggi dibandingkan dengan aplikasi NPK Ponska 300 kg ha-1 tanpa aplikasi pupuk organik. Dosis aplikasi pupuk organik padat untuk tanaman jagung, kacang tanah, kacang panjang dan cabe yang diusahakan pada tanah tegakan jambu mete 25 ton ha-1 dengan waktu aplikasi setelah pengolahan tanah.

Abstract

The aim of this community service activity is to train and mentor farmers to produce organic fertilizer from cattle pen waste to create a village community that is self-sufficient in meeting the fertilizer needs for its pineapple farming business. The activity used a participatory action method, which was carried out for 19 months. The results of the activities show that the implementation of the activities ran smoothly and successfully. Farmers' participation and enthusiasm, which was previously moderate, turned out to be increased to high after implementing direct assistance in the field. Farmers' knowledge and skills are increasing as evidenced by the fertilizer produced based on SNI standards which is classified as good quality. Organic fertilizer produced by farmers can be used as a substitute for Urea, ZK and TSP fertilizer because application of a dose of 25 tons ha-1 plus NPK Ponska dose of 100 kg ha-1 can balance the growth and yield of pineapple in plots fertilized with NPK dose of 500 kg ha-1 . So the recommended application dose for organic fertilizer produced by this program is 25 tons ha-1 plus NPK Ponska 100 kg ha-1 with the application time after soil processing.

Abstract

The aim of the research was to determine the diversity, distribution, dominance, and yield loss of corn due to competition from broadleaf weeds. Descriptive research method with direct survey techniques of research objects. Data were collected using 10 sample plots measuring 1 m2, which were placed using random sampling. Observation parameters include the population and dry biomass weight of weeds and corn. The data was analyzed descriptively and comparatively by calculating density, frequency, and dominance to obtain an important value index and summation diminance ratio (SDR). The results of the research showed that 14 species of broad-leaved weeds were found with high species diversity, distribution, dominance, and abundance indices. The competitiveness and relative weighted dominance of six weed species, namely Amaranthus spinusus, Amaranthus gracilis, Synedrella nodiliflora, Acalypha indica, Ageratum conyzoides, and Alternanthera philoxeroides, are higher than those of other weed species, causing corn yield losses of 5.56%–21.90%. Therefore, these six weed species must be controlled.

Abstract

The aim of the research is to examine the effect of intercropping corn with leguminous crops on weeds and land use efficiency. The experimental research method was designed using a randomized complete block design (RCBD) with three blocks. The treatments tested were monocrop planting patterns and intercropping between corn and leguminous crops. The results of the research showed that 16 weed species were found with high species diversity, evenness, dominance, and abundance, so that there were six dominant species that existed during plant growth. Peanuts and cowpeas are suitable for intercropping with corn because they can suppress the population and growth of weeds. Soybeans, green beans, and red beans are not suitable because they are not effective in suppressing the population and growth of weeds and compete with corn, so that corn yield losses due to competition are 38.20%–40.96% and due to weed competition, they reach 62.37%–63.77%.  The best ecological and agronomic land use efficiency was obtained by intercropping corn with peanuts and cowpeas, with NKL values based on dry biomass weights of 1.90 and 1.89 (NKL > 1) and dry seed weights of 1.79 and 1.78 (NKL > 1).

Abstract

The study aimed to describe and inventory the diversity of medicinal plant species used by the people of Bayan traditional village. The study used descriptive methods and data collection using survey techniques and semi-structured interviews. The survey location was determined by random sampling in the yards of the Sasak, Balinese, and Javanese tribes, each with three sampling points. Parameters observed were population characteristics, morphology, and how to use medicinal plants. The results showed that medicinal plants were found in the yards of the Javanese tribe in 50 species with 1197 individuals, the Balinese tribe in 47 species with 974 individuals, and the Sasak tribe in 35 species with 548 individuals. The dominant species with the highest abundance index were star gooseberry, agathi, turmeric, ginger, white tumeric, halviva, cat's whiskers, and noni. The medicinal plant species found have been used to treat 28 kinds of diseases. The form of plant life that is widely used for medicine is herbaceous. The part of the plant organ that is most widely used for traditional medicine raw materials is the leaf. The most common way to process medicinal plants is by boiling them, then drinking boiled water, finely grinding them, and drinking the juice.

Abstract

The causes of the low productivity of cocoa plants in the village of Rempek are that the plantations are planted with inferior seeds, the sanitary conditions of the plantations are poor, they receive little care, and the plants are old. Solutions to address these problems include: intensive care of the plantations, frequent, light, and simple pruning of the plants, integrated pest management, application of organic fertilizers, and rejuvenation of the plants through a polyclonal system. Another problem that needs to be addressed is the lack of knowledge and skills of farmers in managing cocoa plantations in the polyculture system. Furthermore, the entrepreneurial skills and agricultural knowledge of the farmers are also inadequate. Due to these issues, a training and support program has been established aimed at improving the knowledge and skills of farmers in managing cocoa plants in the polyclonal system. The execution of the training activities proceeded orderly, safely, and smoothly. The knowledge and skills of the participants in cultivating cocoa plants improved, as evidenced by the participation rate and the initially low enthusiasm, which could be raised to a high level after participating in the training. The management of cocoa plantations with a polyclone system and the intensive application of agronomic practices leads to a significantly higher total number of cocoa fruits per tree and a higher total weight of dry cocoa per tree compared to cocoa plantations that are only sporadically maintained and those that are not maintained as well as monoclonals.
