Bakri B, Warsito W, Karimudin Y. 2019. Characterization of raw land in Pulau Rimau to support liquid waste application land palm oil factory. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 90-96. Palembang: Unsri Press.The study aimed to determine the physical and chemical properties of soil to support Land Application of palm oil mill effluent. The research method is carried out by survey method by taking soil samples at several depths. The results showed pH (2.98 - 2.93), C org (38.22 - 61.62 g / kg), N tot (0.84 - 0.95), P brey 1 (1.35 - 1 , 80 mg / kg), K-dd (0.19 - 0.32), Na (0.55 - 1.09 cmol / Kg), Ca (1.8 - 3.23 cmol / kg), Mg ( 0.55 - 1.81 cmol / kg), CEC (17.40 - 19.58 cmol / kg), KBL (14.94 - 32%), Sand (36.99 - 40.94%), Dust ( 40.63 - 55.57%), Clay (7.55 - 22.38%), BD (0.74 - 1.08 g / cm³), RPT (60 - 72%), Permeability (0.27 - 3.45 cm / hour). The results of the analysis show that nutrient-poor soils, but the physical condition of the soil is quite helpful for the media providing land applications for palm oil mill effluent.Keywords: palm oil mills, soil properties, waste

Abstract

Sulistyani DP, Napoleon A, Hermawan A, Bakri B, Warsito W, Riza MFR.  2022. Liquid organic fertilizer (Poc) from tofu liquid waste with banana hump decomposer in pokcay plant growth. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 129-135.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Tofu liquid waste can be used as a new alternative that can be used as liquid organic fertilizer because in the tofu liquid waste it has various nutrients needed for the plant growth process. Based on the research, it shows that the nutrient content in tofu liquid waste before and after liquid fertilizer is made does not meet the standard of liquid fertilizer. To improve the quality of tofu liquid waste as liquid fertilizer, one of them is the addition of local microorganisms (MOL) from banana hump. The specific purpose of the study was to determine the effect of liquid organic fertilizer from tofu liquid waste with the addition of a banana hump decomposer on pokcay plants. Liquid organic fertilizer is one of the efforts to improve the physical and chemical properties of the soil, one of which is Ultisol, so it is expected to increase the growth of pokcay plants to be applied. Ultisols include soils that have very low nutrients and high soil acidity. Poor macronutrient content. Therefore, researchers made efforts so that ultisols could increase the availability of soil nutrients. Liquid organic fertilizer has many advantages, namely the ease of application to soil and plants, which only needs to be watered. The results showed that there was an effect of the dose of liquid organic fertilizer sprinkled on the soil planted with pokcay on the growth, namely plant height, number of leaves, leaf green level, wet weight and dry weight.

Abstract

Achadi T, Haikal U, Angraini L, Ghifari MA, Yakup Y, Marlina M, Warsito W. 2022. Growth and yield of legume crops with liquid organic from various fruit residues. In : Herlinda S et al. (Eds), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 217-225. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Liquid organic fertilizer is the result from decomposition of organic matter derived from animals or plants. Liquid organic fertilizer is made from damaged or rotten fruit and from the skin of the fruit (banana, papaya, pineapple and a mixture of all three). This study aimed to determine the effect of liquid organic fertilizer (POC) on the growth and yield of legumes (Soybeans, Peanuts and Green Beans). This research was conducted from July to October 2022. This study used a Complete Randomized Design with eight treatments including controls, namely A (recommended NPK fertilizer), B (POC of banana fruit residue), C (POC of pineapple fruit residue), D (POC sis of Papaya fruit), E (POC of banana + pineapple fruit residue), F (POC of banana + papaya fruit residue), G (POC of pineapple fruit residue + papaya) and H (remaining banana fruit + pineapple + papaya). The results showed that liquid organic fertilizer were not significantly different the recommended NPK fertilizer to all variables with out number of branches and productive branch of Soybeans and numbers of branches of Peanuts so hope that liquid organic fertilizer from Various Fruit Residues increase to Yield of Legume Crops (Soybeans, Peanuts and Green Beans).

Abstract

Setyawan D, Maren A, Budianta D, Warsito W, Priatna SJ. 2022. Liquid organic fertilizer from pineapple peel waste for rural rubber land improvement in West Payaraman, Ogan Ilir. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 878-884.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Rubber plantations are an important source of income in Payaraman District, Ogan Ilir and are generally cultivated on marginal lands. Meanwhile, pineapple peel waste that is not utilized will pile up into garbage even though it can be used as liquid organic fertilizer or compost. This study aimed to assess the effectiveness of POC pineapple peel waste in increasing soil N, P, and K nutrients and latex production. The study used a split plot design with the main plot of weed clearing (without and with weeding) while the subplots were POC doses of 0, 1, 2, 3 and 4% (equivalent to 0, 10, 20, 30 and 40 ml POC). per liter of water). Watering is done with a frequency of once per week. The treatment was repeated three times. The experimental unit consisted of 30 mature rubber trees. Latex is collected weekly. The results showed that the POC of pineapple peel had a pH of 3.95; 0.05 % N; 0.027 % P and 0.19 % K. The initial soil pH value from 4.13 to 4.18 increased to around pH 5.0 after POC application for 4 weeks. Likewise, the total N content is about 0.26%; P-total 100 mg/kg and K-total 14 mg/kg. ANOVA results showed that the best treatment was a dose of 30 ml/liter with a latex production of 770 g/tree. Based on these observations, it can be concluded that the POC of pineapple waste has the potential to improve soil fertility and latex production. Weeding is important to reduce nutrient competition with rubber plants.
