Pelepah sawit berpotensi sangat besar untuk dikembangkan menjadi pupuk organik. Setidaknya ada 3 kelebihan pelepah sawit dibanding bahan lainnya yaitu pertama, kita memiliki lahan perkebunan sawit yang sangat luas; kedua, pelepah sawit tersedia sepanjang tahun dengan harga murah atau bahkan gratis; danÂ ketiga sudah ada teknologi untuk mencacah pelepah sawit yang keras yaitu mesin chopper. Dengan tiga pertimbangan diatas kami mengembangkan pupuk POPS atau pupuk organik pelepah sawit. Untuk mengevalusi seberapa efektif pupuk ini, kami telah melaksanakan penelitian selama dua tahun pada tanaman padi sawah dengan metode pertanian organik. Sebagai pembanding kami menggunakan bokashi pupuk kandang dan pupuk kimia. Tiga taraf dosis digunakan untuk melihat respon tanaman terhadap perbedaan tingkat hara yang diberikan. Hasil penelitian menunjukkan bahwa pada tahun pertama penelitian hasil padi dengan menggunakan pupuk pops lebih rendah dibandingkan dengan aplikasi pupuk kimia yaitu 5,16 dan 5,39 ton per hektar berturut-turut untuk pupuk pops dan kimia. Namun pada tahun kedua, hasil padi dengan pupuk pops meningkat signifikan sedangkan dengan pupuk kimia hasilnya menurun sehingga terjadi perubahan ranking dimana pupuk pops menjadi lebih tinggi hasilnya dibanding pupuk kimia yaitu 6,47 ton per hektar untuk pupuk pops sedangkan pupuk kimia hasilnya hanya 4,77 ton per hektar. Dari sini kami menyimpulkan bahwa aplikasi pupuk pops berdampak positif pada peningkatan produksi padi secara berkelanjutan dimana hasil tanaman padi akan meningkat seiring waktu.Â Kata kunci: pelepah sawit, pupuk organik, pertanian organik, padi

An intensive research about the application of Oil palm frond (OPF) organic fertilizer on paddy rice and soybean had been done for consecutive three years. The crops showed better growth and yield by years by OPF organic fertilizer compared to farmyard manure and chemical fertilizer. This finding was due to the adequate nutrient contents in OPF organic fertilizer which consist of more than 4% of N, P and K as required by national organic standard (SNI). However, the C/N ratio was rather high which more than 25%. This research aimed to evaluate new formulations of OPF organic fertilizer with the intention of finding ideal C/N ratio as required by SNI. In order to meet this objective, the study was conducted by mixing OPF chopped with various high N content organic materials. The best formulation was mixing of OPF chopped with oil palm leaves, farmyard manure and fish waste liquid fertilizer. The N content in this new formulation was 2.10% which was higher than previous OPF formulation 1.52%. Thus the C/N ratio became much lower in new formulation compared to previous one, 13.83% and 35.96% consecutively.

Oil palm fronds have huge potential to be developed as a source of organic fertiliser by chopping hard frond to become soft smooth pieces and ready to be proceed in bokashi fertilising system. This research aimed to evaluate the application of oil palm frond organic fertiliser on soybean growth and yield compared to cow manure and chemical fertilisers. Three levels of Nitrogen were applied 60, 90 and 120 kg of N/ha. This study had been done in Padang Rambun village, Seluma District, Bengkulu Province under wet land rice field condition and using rice-soybean rotation. Split plot design and least significant design (LSD) 5% were applied to analyse the data. The results showed that kinds and dosage levels gave very significant effect to all parameters but there was no significant effect between them. LSD analysis proved that oil palm frond organic fertiliser was better than manure bokashi in term of plant height and number of pods but had no significant effect on weight of seeds per plot. Furthermore, increasing of nitrogen level improved growth and yield of soybean meaning that the dosage given did not meet the optimum level for soybean growth and yield.

The investigation was done to use the allelopathical potency of tested weeds as botanical herbicide, to find the best concentration of weed extract, to find the effect of allelopathy to either weed of onion or the onion. The experiment was carried out in experimental land of Agriculture Faculty, The University of Hazairin, North Bengkulu and Laboratory of Agronomy for four months.The experiment was arranged factorially in a randomized block design with three replications. The kinds of extract weeds were Imperata cylindrica, Cyperus rotundus, Mikania micrantha and Ageratum conyzoides. Concentration was applied at 0%, 10%, 20%, 30%, and 40%.The result concluded that extract, concentration or interaction of the two not only affected insignificant to growth and yield of onion but also dry weight of weed. However, extract of Cyperus rotundus tent to suppress the weed around the onion. Concentration of extract showed inconsistent response to all parameters. It probably because the concentration was still low so that the effect of maintenance was dominant.

The availability of farm inputs which can be gotten easily, cheaply at anytime is one of important keys to successful of organik agriculture practice. Organik fertilizer which is made of fronds of oil palm, or we call it POPS fertilizer, is an alternative fertilizer that fulfill that expectation. There are at least four advantages of using fronds as source of organik fertilizer are available in abundant amounts, very cheap or even free, as product product and could be chop by using chopper machine. A research had been done in irrigated wetland field located in Padang Rambun village in Seluma District, Bengkulu Province from January to May 2018. A split plot design was used to analyze three kinds of fertilizers were POPS, cow manure bokashi and anorganik fertilizers and three levels of nitrogen dosages were 120, 90 and 60 kg/ha. The results showed that POPS fertilizer gave the best rice performances on height, number of tillers, number of productive tillers and yield (6.81 ton/ha). In addition, the highest dosage provided best yield by 6.69 ton/ha. Finally, the rice productivity has consistently increased since the first year of POPS fertilizer application.

In our country, marginal land occupy for about 50 million hectares or almost one forth of total land. In Sumatra, nearly all marginal land is dominated by podzolik soil which about 10 million hectares. The main problems of this soil are including low pH, high Al content, low cation exchange capacity, and poor of nutrient and organic matter level, therefore the growth and yield of plants can not be optimal. Traditionally, farmers use lime to solve this problem, but this method only influences the chemical aspect but not the biological one. The solution we offer in research is by applying biochar. It is high in carbon, porous and could improve soil fertility. This research aimed to know and evaluate the impact of biochar application on growth and yield of corn. The result showed that biochar gave positive impact on growth and yield of corn. By using biochar the corn height reached 155,67 cm while applying lime could only grew till 56 cm and 20 cm by using no ameliorant or control. Furthermore, the corn seed weight was thrice by biochar than by lime that were 194,5 g compared to 42 g per plant. Meanwhile, the corn plants were failed to produce yield in treatment of chemical fertiliser and control.

Indonesia is the second greatest fish producer in the world after China with a total production of almost seven million tonnes in 2018. Meanwhile, Bengkulu is one of the provinces that are rich in fish resources. However, about 30-60% of fish produced is considered fish waste. Ikan rucah is small fish that has low or no economical value, thus it is regarded as a waste. Ikan rucah should be managed to avoid its negative effects on the environment. One of the options is by transforming it into organic fertilizer. Nevertheless, producing organic fertilizer by using fish waste is complicated since it will be easily rotten in futile fermentation. Thus, the objective of the research was aimed to evaluate the maturity of fish waste bokashi by using three parameters including physical, chemical, and biological aspects. The study had been carried out in the Laboratory of Agrotechnology, Faculty of Agriculture, University of Hazairin, Bengkulu in late 2020. The research was begun by preparing fish waste in three drying levels that were 85%, 70%, and 30% water content thus they were stated as fresh, medium, and dry fish waste, respectively. Each of those was then fermented in anaerobic methods for 2 and 3 weeks. The bokashi produced then analyzed in the physical, chemical, and biological characteristics. The results of this study confirmed that ikan rucah could be used as a source of organic material for organic fertilizer. Every treatment tested showed a good maturity level in physical parameters. Furthermore, the important findings were the high contents of main nutrients that were 1.5-5% and 4-5%, respectively for nitrogen and phosphorus. In addition, the biological maturity reached after 3 weeks of fermentation that confirmed germination index (GI) of about more than 100% or categorized as highly mature.

Okra is one of many vegetables that could be cultivated in tropical climate countries. This crop also has healthy and pharmacy benefits. However, not many farmers grow okra in Indonesia yet. According to some literatures, okra is sensitive to low pH soil. This problem might be solved by applying organic fertilizer, in this case we tried to use organic fertilizer made from sugarcane baggase which available abundantly in Bengkulu. This research aimed to evaluate the effect of sugarcane baggase organic fertilizer on the growth and yield of okra. This study had been done in January-March 2019 in Bengkulu Province. The treatments were three dosages of sugarcane baggase: 10, 15, and 20 t/ha, and 200 kg of NPK (chemical fertilizer) was used as control. All data were analyzed with Anova and LSD 5%. Some important findings in this research as follow. Firstly, organic fertilizer made from sugarcane baggase had sufficient N, P, and K nutrient contents as required by national standard 2019. Secondly, the organic fertilizer had positive effect on decreasing soil acidity. Thirdly, the organic fertilizer showed similar effect as chemical fertilizer had in terms of plant height and number of pod. However, the chemical fertilizer confirmed significant effect than organic fertilizer on behalf of number of leaves, total weight of pods per plant, and productivity of okra (t/ha). The highest productivity of okra by applying the highest dosage of sugarcane baggase organic fertilizer was 6.01 t/ha, meanwhile it was 8.01 t/ha by applying chemical fertilizer.

One of the essential sub-sectors that should develop to support the agricultural sector is the post-harvest agro-industry. Sederhana is the largest tofu factory in Bukit Peninjauan I village. The factory produces tofu daily to fulfill two traditional markets in Bengkulu City. This study aimed to evaluate the production cost, profit, income, R/C ratio, and added value at every production process. The study had been carried out in the Sederhana tofu factory in Bukit Peninjauan I village, Sukaraja sub-district, Seluma District, Bengkulu Province in November 2020. The data used in this paper were both primer and secondary data. The business qualification was determined by analyzing total cost, profit, income, R/C ratio, and added value. The results of this research showed that the Sederhana tofu factory had good quality business qualifications. For every 400 kg of soybean per production per day, it needed the total cost of Rp. 5,381,056.82. Meanwhile, the profit was about Rp. 6,600,000, and the income reached Rp. 1,218,943.18. Thus, the R/C ratio was 1.23 which was profitable. Besides, the added value was Rp. 6,433.34 per kg of soybean. However, the added value was the gross value since it contained labor income and share.
