Abstract

The provision of appropriate technology for farmers was necessary to optimize the productivity of rice plants, especially in acidic sulfate fields. The purpose of study were to determine optimal dose of NPK fertilizer and right pruning time to increase growth and yield of rice plants in acidic sulfate fields. Research was conducted in acidic sulfate fields of Rasau Jaya Tiga village, Kubu Raya district, from August to December 2022. This experiment utilized a factorial randomized design group, with two factors namely: factor I and factor II. Factor I was NPK fertilizer (N): N1 = 0.9 kg/plot, N2 = 1.8 kg/plot, N3 = 2.7 kg/plot, N4 = 4.5 kg/plot. Factor II was leaf pruning (P): P0 = No Pruning, P1 = Pruning 30 days after planting (dap), P2 = Pruning 37 dap, P3 = Pruning 44 dap, P4 = Pruning 51 dap, and P5 = Pruning 58 dap. Observed variables were plant height, number of tillers, number of productive tillers, number of grains per panicle, amount of grain contained per panicle, and dry weight of grain per plot. Data were analyzed using F and Tukey tests at a 5% level of significance. The interaction of pruning treatment and NPK has an unsignificant effect on all observed parameters. NPK treatment and pruning singularly have a significant effect on all observed parameters. Pruning of the plant at 44 dap (P3) and NPK fertilizer dose of 4.5 kg/plot (N4) yielded the best results in all observed variables. Keywords: Acidic Sulphate Lands,  Fertilizer, Productivity, Pruning, Rice

Abstract

Produksi cabai rawit dalam dua tahun terakhir di kecamatan Rasau Jaya mengalami penurunan produksi yang sangat signifikan. Yang disebabkan oleh serangan organisme penganggu tanaman (OPT) khususnya patogen jamur Fusarium sp. dengan tingkat serangan berkisar 20 – 40 %. Upaya pengendalian patogen penyebab penyakit pada cabai rawit, para petani di desa Rasau Jaya Tiga masih menggunakan pestisida sintetik. Penggunaan pestisida sintetik yang terus -menerus dapat menyebabkan efek toksik pada petani dan mencemari lingkungan. Selain itu, tidak menentunya harga jual cabai mejadi salah satu permasalahan yang dihadapi oleh mitra, salah satu upaya yang dapat dilakukan untuk meningkatkan pendapatan petani pada saat rendahnya harga adalah melakukan pengolahan cabai rawit segar, menjadi cabai rawit olahan menjadi beberapa produk olah sehingga mengurangi kerugian petani dan meningkatkan nilai tambah komoditi. Tujuan dan target luaran kegiatan ini yaitu : 1. peningkatan pemahaman mengenai pencegahan serangan pathogen melalui sanitasi lingkungan dan perlakuan tanaman; 2. berkurangnya tingkat serangan pathogen; 3. peningkatan pemahaman dan keterampilan penggunaan pestisida hayati; 4. berkurangnya penggunaan pestisida sintetik; 5. peningkatan pemahaman dan keterampilan penggunaan jamur Trichoderma sp. dan metabolit sekundernya; dan 6. peningkatan peningkatan keterampilan petani dalam pengolahan cabai rawit segar mejadi produk olahan cabai yang meningkatkan nilai tambah komoditi cabai rawit.

Abstract

Marginal alluvial soils are characterized by low fertility, acidic pH, and limited nutrient availability, which constrain agricultural productivity. This study investigated the effects of goat manure and liquid organic fertilizer (POC) from tofu wastewater on okra growth and yield in alluvial soil. A completely randomized factorial design was employed with two factors: goat manure doses (50, 100, 150 g/polybag) and tofu wastewater POC concentrations (10%, 20%, 30%), each replicated three times, resulting in 27 experimental units. Soil analysis revealed significant improvements in chemical and physical properties after treatment application. Initial soil pH increased from 4.82 to 5.9, organic carbon content rose from 1.82% to 3.05%, total nitrogen increased from 0.16% to 0.42%, and available phosphorus improved from 18.3 ppm to 92.14 ppm. Physical properties also enhanced with bulk density decreasing from 1.62 to 1.24 g/cm³ and total porosity increasing from 34.21% to 46.37%. ANOVA analysis showed significant effects of POC concentration on plant height and fruit weight, with 20% concentration producing optimal results. Goat manure significantly influenced fruit weight, with the highest dose (150 g/polybag) yielding 89.44 g compared to 56.96 g at the lowest dose. No significant interactions were observed between the two factors. The results demonstrate that combined application of goat manure and tofu wastewater POC effectively transforms degraded alluvial soil into fertile growing medium, supporting sustainable okra production in marginal lands.

Abstract

Urea fertilizer has a relatively high nitrogen content (45%) compared to any other nitrogen-source fertilizers. However, due to urea's ability to dissolve readily, nitrogen fertilizer in the form of urea often has a poor efficacy. The environment will lose around 70% of the urea fertilizer during the process, including soil ammonia evaporation and urea degradation. One of the methods to increase fertilization effectiveness is to coat it with slow-release fertilizer technology. The specific objective of this study is to determine the characteristics of urea slow release fertilizer with an encapsulation technique by using natural zeolite biocomposites-alginate and nitrogen release patterns as slow release fertilizer candidates. The characteristics of biocomposites were evaluated using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and spectrophotometer analysis for nitrogen release tests. This experiment used natural zeolite biocomposite-alginate to encapsulate the urea as an environmentally friendly slow-release fertilizer. The FTIR spectroscopy showed the presence of natural zeolite-alginate biocomposite. The SEM images showed the surface morphology of urea which had been coated by a natural zeolite-alginate biocomposite. The percentage of urea released for 72 hours at zeolite-alginate ratio of 1:1, 2:1, 3:1 were 16.10%, 21.03%, and 17.51%, respectively. This result shows that urea encapsulated by biocomposite with 1:1 ratio has the least percentage of urea release compared to the others. The biocomposite with 1:1 ratio exhibited the best performance in resisting nitrogen release from urea fertilizer. This study indicates that natural zeolite-alginate biocomposite is an alternative candidate for developing the efficiency of slow-release urea fertilizer.

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural crop in Indonesia, yet its productivity remains relatively low, especially in suboptimal lands such as alluvial soils. This study aimed to evaluate the effects of combining chicken manure and NPK Mutiara fertilizer on the growth and yield of shallots in alluvial soils of West Kalimantan. The research was conducted from January to March 2025 at the Experimental Garden of the Faculty of Agriculture, Panca Bhakti University, Pontianak, using a factorial Completely Randomized Design (CRD) with two factors: chicken manure (40, 80, and 120 g/polybag) and NPK Mutiara fertilizer (6.22, 7.95, and 9.26 g/polybag). Observed parameters included plant height, number of leaves, number of bulbs, and fresh bulb weight. The results showed that the combination of treatments had no significant effect on all growth and yield parameters. However, the combination of a3n3 (120 g chicken manure and 9.26 g NPK Mutiara) produced the highest average plant height (33.11 cm), while the a2n3 combination resulted in the highest fresh bulb weight (116.67 g). The absence of significant effects is presumed to be due to insufficient nutrient supply under acidic and organic-poor alluvial soil conditions. Further research is needed to determine the optimal dosage and fertilization combination to improve shallot yields on suboptimal land. Recommended to adjust the dosage of chicken manure and NPK Mutiara fertilizer for optimal results, use high-quality seeds with a greater number of active buds, and improve the organic matter content of alluvial soil prior to planting.

Abstract

The Ornamental Grass Waste Bank (BSRH) is an institution with a cooperative legal entity, the establishment of which is facilitated by the Pontianak City Government through the Pontianak City Environmental Service. Until now, BSRH has focused more on managing inorganic waste in handicraft materials, decorations, and souvenirs. Meanwhile, some organic wastes are processed into organic fertilizers. The obstacle faced by the BSRH is the non-optimal management of organic waste into fertilizer because of the lack of skilled personnel in processing waste into organic fertilizer.  This PKM activity aims to transfer knowledge about organic waste processing using effective decomposing microorganisms. The implementation method used in this activity consists of three stages: preparation, implementation and training, and monitoring and evaluation. Based on the results of the activities that were carried out, it was found that all BSRH members who participated in the training and practice of making bokashi from organic waste gained new understanding and knowledge in utilizing organic waste as bokashi fertilizer and interest in applying it in the future. From the questionnaire given, data showed that 80% of BSRH members had never participated in similar activities, while all BSRH members (100%) stated that the training activity on making bokashi fertilizer from organic waste was useful, providing new knowledge and interest in its application. This training and practice of making bokashi fertilizer can provide knowledge and skills for solving problems regarding organic waste in the surrounding environment into more useful materials.

Abstract

Jambu air merupakan salah satu buah tropis yang banyak digemari masyarakat karena rasanya yang manis dan menyegarkan, namun memiliki daya simpan yang relatif singkat pada suhu ruang, yaitu hanya 3–4 hari. Kondisi ini menjadi kendala dalam distribusi dan pemasaran buah segar, sehingga diperlukan teknologi pascapanen yang dapat memperpanjang umur simpannya. Penelitian ini bertujuan untuk mengetahui formulasi edible coating dari pati biji durian terbaik dalam mempertahankan umur simpan dan kualitas jambu air. Penelitian dilakukan melalui tiga tahapan, yaitu (1) ekstraksi pati dari biji durian, (2) pembuatan larutan edible coating, dan (3) pengaplikasian edible coating pada buah jambu air. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor perlakuan, dan hasilnya dianalisis menggunakan sidik ragam (ANOVA) yang dilanjutkan dengan uji Beda Nyata Jujur (BNJ) atau Tukey pada taraf 5%. Hasil penelitian menunjukkan bahwa penggunaan edible coating berbasis pati biji durian berpengaruh nyata terhadap karakteristik jambu air, meliputi kadar air, kadar vitamin C, susut bobot, dan total padatan terlarut pada berbagai perlakuan dan lama penyimpanan. Berdasarkan parameter kadar air dan susut bobot, perlakuan dengan pati biji durian 6% memberikan hasil terbaik dalam menekan penurunan kadar air dan susut bobot selama penyimpanan hingga 15 hari pada suhu ruang. Penelitian ini merekomendasikan pemanfaatan pati biji durian sebagai bahan dasar edible coating yang ramah lingkungan untuk memperpanjang umur simpan buah tropis seperti jambu air dan mengurangi limbah pertanian yang belum termanfaatkan secara optimal.

Abstract

The use of Ultisol soil for agriculture has problems, namely low soil organic matter and acidity. This can be overcome by adding organic matter to the soil to act as an ameliorant. The ameliorant can be applied by utilizing coconut waste that has been processed into bioactive compost charcoal. Bioactive compost charcoal is a mixture of charcoal (biochar) and compost composted using Trichoderma harzianum. This study aims to determine the effect of bioactive compost charcoal and incubation period on soybean growth in Ultisol soil. This study used a completely randomized design (CRD) factorial pattern, consisting of two treatment factors. The first factor was bioactive compost charcoal with 4 levels (0; 5; 10; 15 tons ha⁻¹) and the second factor was incubation period with 3 levels (0; 2; 4 weeks). Each treatment was repeated 3 times, consisting of 3 plants, for a total of 108 plants. The results of this study showed that a dose of 15 tons ha⁻¹ of bioactive compost charcoal significantly increased plant height (46,05 cm), number of leaves (55,19 leaves), root volume (7,44 cm³), and plant dry weight (14,40 g), while a dose of 10 tons ha⁻¹ resulted in the highest number of soybean branches (5,37 branches) in Ultisol soil.
