PT. Dinamika Sejahtera Mandiri (PT. DSM) merupakan perusahaan swasta yang bergerak di bidang pertambangan bauksit dengan sistem penambangan terbuka, sehingga menghasilkan hamparan tanah dengan kandungan bahan organik  dan unsur hara sangat rendah serta toksik tinggi sehingga lahan menjadi kritis. Upaya perbaikan lingkungan dilakukan dengan rehabilitasi lahan agar tidak menimbulkan kerusakan berkelanjutan. PT. DSM menggunakan penambahan biostimulan dalam rehabilitasi lahan, namun karena biaya yang mahal maka dilakukan alternatif menggunakan cocopeat sebagai pengganti topsoil dengan biaya terjangkau. Lokasi penelitian terletak di lahan pascatambang bauksit milik PT. DSM yang berada di Desa Teraju, Kecamatan Toba, Kabupaten Sanggau, Provinsi Kalimantan Barat. Total sampel tanah yang diuji sebanyak 23 sampel, terdiri dari 5 perlakuan dengan masing-masing perlakuan dilakukan pengulangan sebanyak 3 kali, yaitu perlakuan A tanpa perlakuan di lahan dengan topsoil, perlakuan B tanpa perlakuan di lahan tanpa topsoil, perlakuan C 100% cocopeat, perlakuan D 50% cocopeat + 25% arang sekam + 25% kotoran ayam dan perlakuan E 60% cocopeat + 25% arang sekam + 15% kotoran ayam. Hasil penelitian menunjukan kandungan parameter pH, % C- organik, KTK, dan N total dalam media tanam cocopeat memiliki kandungan yang lebih baik daripada topsoil dan tanah pascatambang, namun parameter P2O5, kadar debu, liat, dan pasir, topsoil memiliki kandungan yang lebih baik daripada cocopeat dan tanah pascatambang. Kandungan parameter fisik dan kimia terendah terdapat pada tanah pascatambang. Komposisi media tanam kombinasi cocopeat, arang sekam, dan kotoran ayam memiliki pengaruh yang baik terhadap pertumbuhan tanaman sengon karena memiliki unsur hara yang lebih baik dibandingkan dengan topsoil, tanpa topsoil atau hanya cocopeat saja. Dosis variasi paling optimal dalam pertumbuhan sengon dari segi pertumbuhan fisik tanaman yaitu pada variasi perlakuan kode tanam D, yaitu memiliki pertambahan tinggi tanaman rata-rata 13,7cm dan cabang daun sebanyak 6 helai yang lebih signifikan dibandingkan perlakuan media tanam lainnya. AbstractPT. Dinamika Sejahtera Mandiri (PT. DSM) is a private company engaged in bauxite mining with an open mining system, resulting in a stretch of land with very low organic and nutrient content and high toxicity so that the land becomes critical. Efforts to improve the environment are carried out by rehabilitating land so as not to cause sustainable damage. PT. DSM uses biostimulants in land rehabilitation, but an alternative is to use cocopeat as a substitute for topsoil at an affordable price because of the high cost. The research location is located on the bauxite post-mining land owned by PT. DSM is located in Teraju Village, Toba District, Sanggau Regency, West Kalimantan Province. Total soil samples tested were 23 samples, consisting of 5 treatments with each treatment being repeated three times, namely treatment A without treatment on land with topsoil, treatment B without treatment on the ground without topsoil, treatment C 100% cocopeat, treatment D 50% cocopeat + 25% husk charcoal + 25% chicken manure and treatment E 60% cocopeat + 25% husk charcoal + 15% chicken manure. The results showed that the pH,% C- organic, CEC, and total N content in the cocopeat growing medium had a better range than topsoil and post-mining soil. Still, the P2O5 parameters, the content of dust, clay, and sand, topsoil had better content. Then cocopeat and post-mining land. The lowest range of physical and chemical parameters is found in post-mining soil. The composition of the planting medium combination of cocopeat, husk charcoal, and chicken manure has a good effect on the growth of Sengon plants because it has better nutrients than topsoil, without topsoil, or just cocopeat. The most optimal dose of variation in the evolution of Sengon in terms of physical plant growth is the variation in the treatment of planting code D, which has an average plant height increase of 13.7 cm and six-leaf branches, which is more significant than the treatment of other growing media.

Passionflower is a member of Passifloraceae family, it can be used as medicinal and ornamental plants in addition to its consumption as fruit in the world. Guava (Psidium guajava L.) fruits, which has a rich nutrient content, are consumed both fresh and processed. Passionfruit and guava plants, which can only be cultivated in temperate southern coasts in our country, have gained commercial importance because of the fruits' export potential, high medical importance and nutrient. This study was carried out to determine the effects of some bioactivator applications on the criteria of sapling growth and development of passionflower and guava plants. The experiment was conducted between 2018-2019 under greenhouse conditions. Saplings obtained from seed germination in Akdeniz University Faculty of Agriculture Research and Experiment Area were used as plant material. 3 different commercial preparations called Messenger, Crop-set and ISR-2000 were used as bioactivators. Plant height (cm), stem diameter (mm) and number of leaves (number / plant) were measured weekly, in order to determine the effect of the applications on the growth and development of saplings. At the end of the study, it was determined that the highest average plant height (10.17 cm), stem diameter (13.53 mm) were obtained in ISR-2000 application. The highest average plant height (11.93 cm), stem diameter (16.44 mm) and number of leaves (9.07 units / plant) were obtained from Messenger application in guava plant. When the results obtained are evaluated, it is recommended that ISR-2000 bioactivator can be applied in passionflower sapling cultivation and Messenger bioactivator can be applied for guava sapling cultivation.

Water Waste

The wastewater from washed rice water (WRW) is often recommended as a source of plant nutrients in most Asian countries, even though most current research on WRW lack scientific rigor, particularly on the effects of rice washing intensity, volumetric water-to-rice ratio (W:R), and condition of the WRW before plant application. This research was thus carried out: (1) to determine how various rice washing intensities, fermentation periods (FP), and W:R would affect the nutrient content in WRW, and (2) to isolate, identify, and characterize the bacterial community from fermented WRW. The WRW was prepared at several rice washing intensities (50, 80, and 100 rpm), FP (0, 3, 6, and 9 days), and W:R (1:1, 3:1, and 6:1). The concentrations of all elements (except P, Mg, and Zn) and available N forms increased with increasing FP and W:R. Beneficial N-fixing and P- and K-solubilizing bacteria were additionally detected in WRW, which helped to increase the concentrations of these elements. Monovalent nutrients -N, , and K are soluble in water. Thus, they were easily leached out of the rice grains and why their concentrations increased with W:R. The bacteria population in WRW increased until 3 days of fermentation, then declined, possibly because there was an insufficient C content in WRW to be a source of energy for bacteria to support their prolonged growth. While C levels in WRW declined over time, total N levels increased then decreased after 3 days, where the latter was most possibly due to the denitrification and ammonification process, which had led to the increase in -N and . The optimum FP and W:R for high nutrient concentrations and bacterial population were found to be 3 to 9 days and 3:1 to 6:1, respectively. WRW contained nutrients and beneficial bacterial species to support plant growth.

Preparation of Natural multi-nutrient Slow Release Fertilizer (NSRF) aims to reduce the environmental burden from some waste and increase the efficiency of fertilizer in releasing nutrient content. In this study,slow-release fertilizer was prepared from all natural components from waste which aredried chicken manure (N source), struvite (P source), and palm empty fruit bunch ash (K source). The equal weight of the three main nutrient sources was used with the addition of starch powder as the binder by 10%, 15% and 20% of the total nutrient mixture. The mixture of all nutrient with binder was granulated using pan granulator. Dried NSRF granule was tested using sand bed release method to observe the release profile of the contained nutrient. Based on the results of a 30-day leaching study, it was found that increasing concentration of binder will reduce the release of the nutrient from NSRF granules.

Dry weights and nutrient contents of all aboveground biomass components were estimated for four seed sources of 11-year-old loblolly pine (Pinustaeda L.) grown in plantations of the same spacing on an old-field site of high quality in the hilly region of north-central Arkansas, U.S.A. Soil nutrient content was estimated to a depth of 0.61 m. Stand data averaged over all seeds sources are in agreement with published reports for dry weight and nutrient accumulation for loblolly pine if differences associated with seasonal variation are considered. Seed source significantly affected total dry matter and nutrient accumulations. Estimated total aboveground mean annual accumulation of biomass for the four seed sources ranged from 5.99 × 103 to 11.17 × 103 kg/ha per year. Elemental accumulation (kilograms per hectare per year) ranged from 14.06 to 23.66 for N, 1.54 to 3.45 for P, and 6.96 to 18.43 for K. On the average, trees comprise 84% of the aboveground plant biomass and contain 76% of the N, 77% of the P, and 90%, of the K associated with plant tissue. The significant influence of seed source on these stand values can affect the potential impact of short rotation, total tree harvesting on long-term site productivity. The elemental content of the tree biomass ranged from 7 to 11% of the total N, 20 to 35% of the P, and 14 to 30% of the K in the soil–litter–plant system.

The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).
