Abstract

Pondok Pesantren (PP) mengelola sumberdaya yang terbatas, namun harus dioptimalkan terutama dalam hal makanan yang disajikan pada santri. Asupan makanan pada santri yang tinggal di PP akan berpengaruh pada status gizinya. Risiko akan menjadi lebih besar pada santriwati karena terkait fungsi biologisnya, mengalami menstruasi tiap bulan sehingga risiko anemia menjadi lebih besar pada santriwati jika asupan makanan kurang seimbang. Kurang seimbangnya asupan makanan di PP disebabkan rendahnya food literacy para santri dan pengelola PP. Food literacy adalah pengetahuan tentang sumber dan fungsi makanan. Gerakan sapu bersih anemia dilakukan melalui pendidikan gizi dan pelatihan perancangan menu untuk pencegahan anemia yang bisa diterapkan di PP.  Kegiatan ini dilaksanakan di PP NI dan PPRRSA Kabupaten Jember.  Kegiatan ini berlangsung efektif. Hal ini terbukti dari peningkatan pengetahuan santriwati tentang anemia dan pencegahannya melalui pengaturan asupan makanan serta kemampuan menyusun menu yang sehat dan ekonomis dari para pengelolaPPyang semakin baik.

Abstract

Results of previous research have proven that soil organic matter (humic and biochar compounds) can increase and maintain soil fertility and protect environmental resilience. The purpose of this study was to increase the abundance of microorganisms in young soil (regosol) with biopelet fertilizer composed of a combination of biochar, chicken manure, and shrimp waste to improve soil fertility. The experimental design used was a randomized block design with two factors, namely the composition and dosage of biopelets. The compositions of biopelet were 70% biochar, 15% chicken manure and 15% fish waste (B1); 50% biochar, 25% chicken manure and 25 % fish waste (B2): and 20% biochar, 40% chicken manure and 40% fish waste (B3). The dosage used was four levels (0, 2.5, 5, and 10 t/ha).The results showed that the application of biopelet fertilizer to the regosol soil reduced soil pH from slightly alkaline to near neutral, and the addition of up to 10 t biopelet/ha increased soil organic C content from 1.17% to 1.72%, as well as increasing the availability of N, P, and K nutrients. Improvement in pH, organic-C, and soil macronutrients was followed by an increase in the abundance of soil microorganisms, especially bacteria.

Abstract

Most of the activities of the use of organic fertilizers and natural additions of organic matter in agricultural intensification fields in Indonesia have not been able to compensate for the rate of decline in soil organic matter by the decomposition process. Biochar has a high C level and has the mean residence time in a long period in the soils. It has been proven that biochar applications may increase soil Carbon but have not been able to increase plant production. Therefore, the use of biochar combined with organic waste rich in nutrients is essential to develop. The purpose of this study was to determine the effectiveness of some biochar compositions with sugar cane, chicken manure, fish waste in the form of biopellet fertilizer on improving the chemical properties of sandy soils and the vegetative growth of soybean plants. This study used a completely randomized block design with two factors. The first factor (B) was the composition of biochar consisting of three levels, namely: 70% biochar, 15% chicken manure, 15% fish waste (B1), 50 % biochar, 25% chicken manure, 25% fish waste (B2), and 20% biochar, 40% chicken manure, 40% fish waste (B3). The second factor (D) was the dose of biopellet fertilizers consisting of four levels, namely: control (D0), 2.5 t/ha (D1), 5 t/ha (D2), and 10 t/ha (D3). The results showed that the addition of biopellet fertilizer effectively improved soil chemical properties (pH, C-organic, and CEC) and the availability of N, P, and K of the sandy soil. The effectiveness of increasing the soil total-N varied from 32.42 to 75.79%, P-available varied from 17.46 to 40.69%, and exchangeable K ranged from 8.7 to 25.67%. Improvement of soil chemical properties and the availability of N, P, and K by biopellet fertilizer application increased plant growth but reduced the weight of root nodules.

Abstract

Sandy soil has low productivity; it takes some efforts to gain the quality of sandy soil by giving organic material. The organic materials that can be used are Bokashi water hyacinth and Azolla liquid organic fertilizer. The aim of this study is to know the effect of Bokashi water hyacinth fertilization and Azolla liquid organic fertilizer on the uptake of N element and the growth of soybean plant in sandy soil. This study uses Complete Random Design (CRD) which consists 9 combinations, i.e. B0 (Control), B1 (0g N Bokashi and 0.5g N POC), B2 (0g N Bokashi and 0.4g N POC), B3 (0.1g N Bokashi and 0.4g N POC, B4 (0.2g N Bokashi and 0.3g N POC), B5 (0.3g N Bokashi and 0.2g N POC), B6 (0.4g N Bokashi and 0.1g N POC), B7 (0.4g N Bokashi and 0g N POC) and B8 (0.5g N Bokashi and 0g N POC). The combination of 11,45 gr water hyacinth is equal to 0,3 % N 30 ml and Azolla POC is equal to 0,2 % N on soybean plant which absorbs the highest N and has the highest amount of effective nodules. The nutrient availability is related to nutrient composition which is available in the ground and can be absorbed by plants.

Abstract

Tanah masam merupakan tanah dengan nilai pH rendah, umumnya jumlah populasi mikroorganisme yang terbatas dan konsentrasi unsur hara rendah, terutama ketersediaan unsur hara fosfat. Penelitian ini bertujuan untuk mengetahui pengaruh kemampuan pemberian bakteri pelarut fosfat (BPF) dalam meningkatkan ketersediaan fosfor tanah masam. Penelitian ini dilaksanakan di Laboratorium Biologi Tanah Fakultas Pertanian Universitas Jember mulai bulan Agustus 2020 hingga Juni 2021. Tahapan penelitian yaitu uji kualitatif pelarutan fosfat pada media Pikovskaya agar, uji aktivitas bakteri pelarut fosfat secara kuantitatif pada media Pikovskaya cair di beberapa kondisi masam (pH 4, pH 5, pH 6, dan pH 7), serta uji aktivitas bakteri pelarut fosfat pada dua jenis tanah masam (Inceptisol dan Ultisol). Bakteri yang digunakan yaitu bakteri Pseudomonas sp dan Bacillus valezensis. Parameter yang diamati yaitu perubahan pH, konsentrasi P-tersedia,  respirasi  dan jumlah populasi bakteri. Hasil penelitian menunjukkan adanya aktivitas kedua BPF yang di uji pada media padat Pikovskaya dengan adanya Indeks pelarutan sebesar 2,21  hingga 2,59 dalam kategori “sedang”.  Pengujian aktivitas BPF pada media cair dengan beberapa kondisi pH menunjukkan adanya aktivitas pelarutan fosfat hingga hari ke-15. Kondisi pH 6 memberikan aktivitas pelarutan fosfat yang tertinggi yaitu 21,87 ppm oleh bakteri Pseudomonas sp. Aktivitas kedua BPF pada tanah masam (Inceptisol dan Ultisol) memberikan pengaruh terhadap peningkatan konsentrasi ketersediaan P dibandingkan konsentrasi awal. Pada Inceptisol dengan inokulasi Pseudomonas sp pada hari ke-30 meningkat 65%, sedangkan pada Ultisol meningkat 162%. Aktivitas Bacillus valezensis pada Inceptisol meningkatkan 217% sedangkan pada Ultisol meningkat sebesar 243%

Abstract

Phosphorous (P) contents in many soils are varies highly along with their ability to provide available P to plant growth. Soils may contain very high in total P, but low in available P due to high P adsorbed by soil matrix and all their adsorbing agents. This research which using natural materials was aimed to increase P availability in some high-P absorption soils. The natural materials utilized for extracting P were organic matter, P extracting bacterial, and rock phosphate. Those materials were interacted to high P absorption soils which were: Oxisol, Inceptisol, and Andisol. The detail objectives of this research were: (1) to study the potential of P-extracting agents (organic matter, and P-extracting bacteria) in releasing P of three high P- absorption soils; (2) to quantify the -age of P coming from the treatments; (3) to calculate the efficiency of P utilization by plant; and (4) to quantify Residual P in soils. The P mobility was analyzed by radioisotope technique using KH232PO4 carrier free solution. The results showed that adding soil organic matter increased the available P by 15.24% in Oxisol, 40.18 in Inceptisol, and by 7.34% in Andisol. Plant sorption toward P from % P used efficiency(%-PUE) up to 60 days was still very low, 0.65 to 9.34%. This was in accordance with the residual P in soils which were still quite high ranging from 94% to 96% in Andisol, 91%97% in Inceptisol, and 96%-98% in Oxisol. The implication of the results of this research, however, is that the application of natural materials in improving soil P availability provides a longtimeresidual effect which could give benefit to the following crops.Keywords: Andisols; Inceptisol; Oxisols; P. diminuta; PUE;  rock phosphate[How to Cite: Mudjiharjati A, TC Setiawati and MH Pandutama. 2012.

Abstract

AbstractDue to the limited availability of potassium and phosphate in soil and the high price of their synthetic mineral fertilizers, the importance of minerals-solubilizing microorganismshas been increasingly significant aimed at sustainable agriculture achievement. Apatite and leucite are considerably abundant minerals; however, their solubility is low. This study was aimed to study the effects of the combination of phosphate-and potassium-solubilizing bacteria (PhSB and PSB) and humic acid of cassava as bioleaching agents in the solubilization process of potassium and phosphate from agromineral material. Some leucite agromineral materials were obtained from Situbondo and Pati, while apatite materials were obtained from Tuban and Ciamis, Indonesia. The minerals were treated with 2.10 x 107CFU/g PhSB and 1.61 x 107CFU/g PSB isolates, combined with 100 ppm organic C humic compounds from cassava as the media. The minerals solubility was monitored every two weeks for 12 weeks ofobservation, which includes the concentration of dissolved K and P, as well as the pH of the media. The presence of organic acids was observed to monitor the bacterial activity by using HPLC, while the physical changes of the rock surface due to bacterial dissolution were scanned by using scanning electron microscopy (SEM). The results showed that the highest dissolution of P was recorded at week 4 (344.23 ppm) released from Tuban apatite with the combination of PhSB and PSB under the humic compound.In contrast, the highest K dissolution was obtained at week 6 for Situbondo leucite (44.21 me/100 g) with a combination of humic cassava compound and PSB only. Statistical analyses showed a mark different on both minerals for dissolution of K and P. The SEM result indicates breakage of the rock surface after a three month observation period indicating that the dissolution minerals occurred. Selected organic acids such as citric, ferulic, coumaric, syringic, and malic acids were detected during the treatment.[Keywords: leucite, apatite, humic compounds, organic acid] Abstrak     Ketersediaan kalium (K) dan fosfat (P) dalam tanah terbatas,danharga pupuk sintetik relatif mahal, menjadikan mikroorganismepelarut mineral memegang peranan penting dalam menunjang pertanian berkelanjutan.Batuan mineral apatit dan leusitmerupakan sumber daya mineral dengan ketersediaan tinggi tetapi mempunyai kelarutan mineral rendah. Penelitian bertujuan untukmempelajari pengaruh kombinasi bakteri pelarut fosfat (BPF), bakteri pelarut kalium (BPK), dan humatsingkong sebagai agen bioleachingdalam proses pelarutan K dan P dari bahan agromineral.

Abstract

Phosphorus (P) is one of the essential nutrients that functions is metabolism in plant. Based on these functions, it indicates that nutrient P has an important role for plant growth and production. However, its availability in soil is very low, which is less than 0.01% of the total P. Therefore, the availability of P nutrients in the soil needs to be increased by increasing the activity of soil microorganisms through the use of phosphate solubilization bacteria. This research is aimed to show the changes in the physiological characteristics of tomato plants through the application of phosphate solubilization bacteria and rock phosphate. Experiment using factorial randomized block design (RBD) which consisted of 2 factors with 2 consultation levels on the first factor (phosphate solubilization bacteria) and 4 levels on the second factor (rock phosphate), and it consist of 8 combinationed of phosphate solubilization bacteria and rock phosphate with 3 replicated. The results showed that the combination treatment of phosphate solubilization bacteria and rock phosphate affected the physiological characteristics of tomato plants, especially on the variables of stomata density, leaf chlorophyll, plant height, plant dry weight, fruit weight and plant P-tissue content in the vegetative final phase. The recommendation of an efficient fertilizer combination to improve physiological characteristics and high yields is use the phosphate solubilization bacteria and rock phosphate 0.69 grams Keywords: phosphate solubilization bacteria, physiological characteristic, rock phosphate
