Abstract

Peningkatan jumlah limbah yang dihasilkan oleh industri sangat erat kaitannya dengan penambahan jumlah industri itu sendiri, terutama limbah Bahan Berbahaya dan Beracun (B3). Bagaimanapun, masalah pengolahan limbah B3 merupakan masalah yang sangat krusial. Sampai saat ini masih terjadi keterbatasan fasilitas pengolahan limbah B3 sehingga sebagai alternatifnya adalah perlunya peningkatan-peningkatan cara pengolahan limbah tersebut melalui penelitian dan pengembangan. Dalam penelitian ini Pemadatan/Penstabilan (S/S) digunakan sebagai salah satu cara untuk pengolahan lumpur yang berasal dari industri automobile (PT. Hicom Teck See). Tujuan penelitian ini adalah untuk membuktikan bahwa (S/S) merupakan salah satu cara pilihan untuk pengolahan limbah, membandingkan dan menilai tingkat efektifitas penggunaan semen (GGBS) dan sekam padi, mengukur dan membandingkan nilai kadar resapan air lindi dengan menggunakan metode JLT-13. Sebelum pengolahan, hasil konsentrasi logam berat yang tertinggi pada sampel ini adalah Na (44.2 mg/l) diikuti oleh Fe, Mg, As, Zn, Al, Mn, Cu, Pb dan Ni dan konsentrasi Fe dalam hal ini berada di atas ambang batas Environmental Quality Act (EQA). Hasil penelitian ini juga menunjukkan bahwa S/S merupakan salah satu alternatif metode yang dapat diterapkan untuk mengolah B3. Sekam padi juga efektif untuk menekan laju konsentrasi logam berat sebanyak 50%. Hasil Uji kekuatan (Compressive Strength) dari limbah ini menunjukkan nilai 414 kPa.

Abstract

Porang (Amorphophallus muelleri Blume) is an agricultural commodity with increasing export value; however, its production is limited by challenges in propagation. Bulbil propagation is considered the most effective method, but it is hindered by a dormancy period that prolongs the growth process. One potential solution is the application of cytokinin-type plant growth regulators, such as Benzyl Amino Purine (BAP). This study aimed to determine the optimal combination of BAP concentration and soaking duration to stimulate shoot growth in porang bulbils. The experiment was conducted from September to November 2023 at the Agronomy and Agrostology Laboratory and the UIN Agriculture Research and Development Station (UARDS) screen house, Faculty of Agriculture and Animal Science, Universitas Islam Sulthan Syarif Kasim Riau. A Completely Randomized Design (CRD) with two factors was used: BAP concentration (0, 50, 100, and 150 mg/L) and soaking duration (1, 2, and 3 hours), with three replications. Observed parameters included germination capacity, time to shoot emergence, shoot length, number of shoots, and percentage of rooted shoots. Results showed that the combination of 150 mg/L BAP and 3 hours of soaking produced the best outcomes in terms of germination capacity (100%), time to shoot emergence (21 days), shoot length (34.2 cm), and number of shoots (205). The highest percentage of rooted shoots (59.1%) was observed with a BAP concentration of 50 mg/L, while the best soaking time for rooting (56.7%) was 1 hour. In conclusion, the most effective treatment for promoting porang bulbil sprouting was 150 mg/L BAP with a soaking duration of 3 hours.

Abstract

Biochar with a high organic matter composition is considered to be an ameliorant for Ultisol. Providing biochar as an ameliorant needs to be studied because it will cause an increase in micronutrients, most of which are excessive in Ultisol. This study aims to determine the effect of several levels of biochar dosage from corn cob as a base material on changes in micronutrients in Ultisol soil. This research was conducted in a greenhouse and in the Laboratory of Agrostology, Feed Industry and Soil Science, State Islamic University of Sultan Syarif Kasim Riau. Experiments with several doses of biochar as treatment, e.g., 0%, 5%, 10%, and 15% of the composition of the growing media were arranged in a Completely Randomized Design (CRD) with six replications. The parameters observed were the micronutrient content of Boron (B), Copper (Cu), Zinc (Zn), Iron (Fe) and Aluminum (Al). The experimental results showed that giving corn cob biochar with doses of 0.5%, 10% and 15% did not significantly change the levels of B, Cu and Zn Ultisol. Biochar at a dose of 10% significantly increased the soil Zn content and decreased Al-dd Ultisol solubility.
