Abstract

Pokdarwis Bokoharjo merupakan kelompok sadar wisata Prabu Boko yang terletak di kawasan Prambanan, Sleman yang dikelilingi oleh Candi Boko dan Candi Banyunibo. Pokdarwis Prabu Boko aktif dalam kegiatan budaya dimana sebagian besar anggotanya bekerja sebagai tour guide serta bersama dengan Bumdes mengelola Candi Banyunibo. Hasil observasi menunjukkan mitra pernah memiliki UMKM yang memproduksi makanan keripik singkong namun karena pandemic Covid-19, kegiatan UMKM Pokdarwis tersebut terhenti, sehingga perlu dilakukan pemberdayaan kembali UMKM tersebut agar dapat membantu pemulihan pendapatan mitra dengan cara memproduksi makanan khas Bokoharjo. Langkah pendampingan yang dilakukan antara lain melakukan sosialisasi kepada mitra, menentukan produk unggulan yang akan diproduksi, memberikan pelatihan produksi produk inovatif pangan, pelatihan pengemasan serta pelatihan manajemen usaha dan pemasaran. Hasil program ini adalah terbentuknya kembali UMKM Pokdarwis, terciptanya makanan khas Bokoharjo yaitu getuk kimpul dan wedang dupak serta peningkatan pengetahuan mitra terhadap kimpul dan rempah-rempah maupun peningkatan keterampilan mitra dalam pengolahan produksi makanan yang baik maupun manajemen pengolahan usaha dan pemasaran.

Abstract

A hand-held spectrometer can be used to evaluate oil palm (Elaeis guineensis Jacq.) leaf nutrient contents without being destructive. This study aims to develop regression equations and analyze the performance of the prediction models for Nitrogen, Phosphate, and Potassium leaf nutrient contents. The dependent variable in this study was the result of the analysis of nutrient contents in frond number 17 which was carried out in the laboratory, while the independent variable was the leaf reflectance value scanned with a hand-held spectrometer. The Normalized Difference approach is used to create a vegetation index from the combination of reflectance values at two wavelengths. Vegetation index with the highest correlation value to the nutrient content of leaves, is used to make a prediction model for leaf nutrients using the Simple Linear Regression. The regression equations formed to predict the contents of nutrients N, P, and K have high R2. The RMSE values of the predicted contents of N, P, and K nutrients, respectively were 0.21, 0.01, and 0.13; and correctness values of those nutrients respectively were 93.29%, 95.5%, and 88.81%. Keywords:  Hand-held spectrometer,  Oil palm,  Prediction,  Leaf nutrients contents.

Abstract

This study aimed to develop a prediction model for the nutrient content of N, P, K, Mg, and Ca in oil palm leaves using the Normalized Difference RedEdge (NDRE) vegetation index derived from multispectral camera data. Data acquisition was carried out by an unmanned aerial vehicle (UAV), which was correlated to leaf sample analysis of the 17th frond number. Results showed that simple regression analysis successfully represented nutrient content (N, P, K, Mg, and Ca) based on NDRE values. Based on the MAPE and Correctness values, the nutrient content prediction model for N and P yields reliable results, while for K, Mg, and Ca, they are considered good, with Correctness values of 95.5%, 96.6%, 88.8%, 87.3%, and 90.0% for N, P, K, Mg, and Ca, respectively. The study found that the NDRE vegetation index can be used to predict the nutrient content of oil palm leaves with  reliable results in accuracy for N and P, and good accuracy for K, Mg, and Ca. This is a promising finding, as it could lead to the development of a non-destructive and rapid method for monitoring the nutrient status of oil palm trees, with the validation models for N, P, K, Mg, and Ca are yN = 1.1089x - 0.2497, yP = 0.99x + 0.002, yK = 1.204x - 0.1576, yMg = 0.9149x + 0.0183, and yCa = 1.0418x - 0.0218. Keywords: Multispectral Cameras, Oil Palm, Leaf Nutrient Contents, Prediction.

Abstract

This study aims to develop an empirical estimation model of oil palm production through the canopy cover area approach and oil palm vegetation index with multispectral camera technology. The oil palm production estimation method was carried out by comparing the NDVI and NDRE index transformation algorithms. The basis for estimation an area of ± 0.3 ha. The results showed that there is relatively strong relationship between canopy cover area and FFB production (kg) with a coefficient of determination R² = 0.573. The results also revealed that NDVI value and the number of FFB have a fairly strong relationship with R² of 0.488. The NDRE value correlated to the number of FFB at a strong relationship with R² of 0.605. 4) the results of the analysis between NDVI Value and FFB Production (kg) have a strong relationship (r = 0.704) with a coefficient of determination of R² = 0.496; 5) the results of the analysis between NDRE Value and FFB Production (kg) have a strong relationship (r = 0.797) with a coefficient of determination of R² = 0.635; 6) The NDRE value is the independent variable that provides the best response, both to the Number of FFB and FFB Production (kg); 7) the best regression equation obtained for FFB production (kg) is Y(FFB Production (kg)) = 1153.8– (3621.9*NDRE); and 8) the best regression equation obtained for the number of FFB is Y(Number of FFB) = 113.98 – (379.53*NDRE). Keywords: Canopy cover area, Multispectral camera, NDRE, NDVI, Oil palm production.

Abstract

Abstract:  The aloe vera plants cultivated by the Sumber Rejeki Women Farmers Group are currently in poor condition, characterized by yellowing leaves. This indicates a significant nutrient deficiency. However, the group members lack the skills to produce organic fertilizer. To address this, community service initiatives are needed to provide training on the production and application of Liquid Organic Fertilizer (LOF) using locally available materials, specifically goat manure and aloe vera leaf scraps. The primary objective of this program is to empower the members with the practical knowledge to create and apply this organic fertilizer to restore the health of their aloe vera crops. employed methods such as socialization, construction of fermentation barrels, hands-on training, evaluation, and mentoring. The training significantly improved participants' understanding, with overall comprehension of liquid organic fertilizer (increasing by 47%, knowledge of production methods rising by 41%, awareness of benefits growing by 29%, and familiarity with materials increasing by 50%. The resulting liquid organic fertilizer had an average composition of 0.56% organic carbon, 0.03% total nitrogen, 0.02% P₂O₅, 0.07% K₂O, and a C/N ratio of 18.86. Aloe vera plants fertilized with this liquid organic fertilizer exhibited greener fronds, a higher number of fronds, longer fronds, and an average frond weight of 300-400 grams.Abstrak: Tanaman lidah buaya milik KWT Sumber Rejeki mengalami penurunan kualitas yang ditandai dengan pelepah berwarna kekuningan. Kondisi ini menunjukkan kurangnya nutrisi, namun para anggota belum memiliki keterampilan untuk memproduksi pupuk secara mandiri. Oleh karena itu perlu dilakukan pelatihan pembuatan Pupuk Organik Cair (POC) dengan memanfaatkan bahan-bahan lokal yang tersedia yaitu kotoran kambing dan sisa-sisa pelepah lidah buaya. Tujuan pengabdian masyarakat ini adalah memberikan pelatihan pembuatan pupuk organik cair berbahan baku kotoran kambing dan sisa-sisa pelepah lidah buaya serta aplikasinya pada tanaman lidah buaya. Metode yang dilakukan meliputi sosialisasi, pembuatan tong fermentasi serta pelatihan dan praktek pembuatan pupuk organik cair serta evaluasi kegiatan dan pendampingan. Tingkat pemahaman peserta pelatihan POC terdapat kenaikan 47%, dengan tingkat pemahanan sangat paham 18% dan cukup paham 82%. Pengetahuan peserta mengenai cara pembuatan POC meningkat sebesar 41%  dengan tingkat pemahanam 9% sangat paham dan 91% cukup paham. Pemahaman mengenai manfaat POC mengalami peningkatan 29% (tadinya  71% menjadi 100% peserta). Pemahaman mengenai bahan-bahan yang digunakan untuk membuat POC meningkat sebesar 50%. POC yang dihasilkan mempunyai rata-rata kadar C-organik 0,56%, kadar N total 0,03%, kadar P2O5 0,02%, kadar K2O 0,07% dan rasio C/N sebesar 18,86. Tanaman lidah buaya yang dipupuk dengan POC akan memiliki warna pelepah yang hijau, jumlah pelepah lebih banyak, pelepahnya lebih panjang dan berat pelepah sekitar 300-400 gram
