Pengabdian masyarakat penting untuk dilakukan guna mengembangkan tatanan maupun taraf hidup masyarakat di suatu daerah. Salah satunya di Nagari Sungai Kambut yang mana banyak penduduknya belum atau tidak bekerja dan sebagian lainnya hanya mengurus rumah tangga. Jumlah petani maupun pekebun juga tidak begitu banyak. Oleh sebab itu dilakukan pengabdian berupa pendampingan dalam mengoptimalkan pemanfaatan pekarangan rumah untuk ditanami buah-buahan. Harapannya dapat menambah pengetahuan dan meningkatkan keterampilan penduduk setempat. Buah-buahan yang dihasilkan juga bisa menjadi sumber penghasilan, selain hanya untuk konsumsi sendiri. Kegiatan pengabdian diawali dengan sosialisasi, penyuluhan dan diikuti pendampingan penanaman tanaman buah. Selama sosialisasi warga aktif melontarkan berbagai pertanyaan baik dari cara menanam, pemeliharaan bahkan pasca panen. Melihat respon masyarakat yang antusias menunjukkan program pengabdian ini mempu meningkatkan pengetahuan tentang pentingnya pemanfaatan pekarangan, terutama untuk penanaman buah. Antusiasme mereka menjadi bukti rasa ingin tahu yang cukup tinggi. Di samping itu, kegiatan ini menjadi sarana pembelajaran masyarakat serta mampu melatih mahasiswa untuk mendorong masyarakat, sehingga mau melakukan penanaman buah melalui pemanfaatan lahan pekarangan.
<p>The bleaching process at the crude palm oil (CPO) refinery stage is one of the processes sufficient to determine the quality of the cooking oil produced. CPO is refined to eliminate the unacceptable substances before consumption. The process produces spent bleaching earth (SBE) and deoiled bleaching earth (DBE) classified as hazardous and toxic material waste. However, according to several studies, SBE and DBE have the potential as filler materials in NPK fertilizers. This study aimed to study the effect of SBE and DBE filler-based NPK fertilization on the soil nutrient status and growth characteristics of soybean, thereby determining if the SBE and DBE materials can be used to replace some of the filler components in the NPK fertilizers. The study was a single factor experiment arranged in a Randomized Complete Block Design (RCBD) consisting of four blocks as replications. The treatments tested were fertilization of 10% bentonite clay mineral filler-based NPK (control), 5% bentonite clay mineral + 5% SBE filler-based NPK and 5% bentonite clay mineral + 5% DBE filler-based NPK. The data were analyzed using ANOVA and tested using LSD test at a 95% confidence level. The results showed that the SBE and DBE materials could partially replace the filler components in bentonite clay filler-based NPK fertilizers, which were shown to have the same effect on soil chemical properties and levels of heavy metals after treatment, levels and uptake of N, P, K, Ca and Mg in plants tissues and growth characteristic in the form of total dry weight.</p>
The objective of the study was to study the effects of spent bleaching earth (SBE) and deoiled bleaching earth (DBE) filler-based NPK fertilizers on the agronomical characteristics of soybean as a model crop. A field experiment was arranged in a single factor of randomized complete block design (RCBD) with four blocks as replications. The treatments were 1) NPK fertilizer with 10% of BC (control), 2) NPK fertilizer with 5% of BC + 5% of SBE, and 3) NPK fertilizer with 5% BC + 5% DBE. The variables observed were the levels of heavy metals in leaf tissue and the agronomic characteristics of soybean plants. The observations were made on several variables of agronomical crop characters. The data were then analyzed with analysis of variance (ANOVA) at 5% levels and continued with the Least Significant Difference (LSD) test if there were differences among treatments. The results confirmed that the SBE and DBE materials could partly replace the filler components in NPK fertilizers, which has been proven to have the same impact on the agronomical characteristics of soybean in the form of leaf area, root volume, number of pods per plant, number of seeds per plant, and seed yield per hectar.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
