Abstract

Plantations of fast growing tree species are imperative in climate change mitigation efforts as of their enormous potential for carbon storage and, this potential largely affected by tree species type. This study estimates biomass and soil organic carbon (SOC) under fast-growing tree species in western Ethiopia. Parameters, height (H) and diameter at breast height (DBH) were measured in permanently plots to evaluate the biomass carbon stock of selected species. Soil samples (0–15 and 15-30 cm) were also collected to determine soil organic carbon (SOC) and bulk density. Above and below-ground biomass (AGB) and (BGB) were estimated using the species-specific allometric equations while SOC was analysed in the laboratory. The results showed that the highest biomass carbon stock was recorded for Eucalyptus globulus (5.7Mg C ha-1) and the lowest was recorded for Eucalyptus grandis (1.2 Mg C ha-1). The highest and lowest mean total soil organic carbon (SOC) was recorded for Eucalyptus saligna (60 Mg C ha-1), and Eucalyptus viminalis (35.4 Mg C ha-1), respectively. This study revealed plantation sites could enhance carbon stock accumulation both in the biomass and soil organic carbon. Hence, considering of incorporating fast growing tree species in plantations is useful in climate change mitigation strategies.

Abstract

ABSTRACT Plant-Microbial Fuel Cell (P-MFC) is a green technology because it uses a biocathode in the cathode compartment and also uses microorganisms to break down the chemical energy of organic matter into electrical energy. In this research, molasses and Saccharomyces cereviceae were used as substrates and Ceratophyllum demersum as a biocathode in the cathode compartment. The purpose of this study was to determine the potential variation in plant weight of C. demersum as a biocathode in the P-MFC system. The results of this study indicated that the maximum current at the biocathode was at a weight of 70 g, namely 0.180 mA with a power density value of 13.664 mW.m-2 and the maximum potential difference at the biocathode was at a weight of 40 g, which as 0.310 mV with a power density value of 30.787 mW.m-2. Therefore, coontail water plant has the potential as biocathode. Keywords:  biochatode, molasses, P-MFC, raccoon tail water, Saccharomyces cereviceae

Abstract

ABSTRAK  Padatan lumpur tinja (cake) merupakan hasil olahan dari instalasi pengolahan lumpur tinja (IPLT). Cake kering yang dihasilkan IPLT Banyuroto sebanyak 33,6 m³/bulan dan kondisinya belum ada pemanfaatan lanjutan, sehingga hanya menjadi timbulan limbah. Salah satu upaya lanjut yang dapat dilakukan adalah dengan mengolahnya menjadi Pupuk Bokashi Tinja (PBT). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan Jerami dan sekam padi pada kualitas PBT serta menentukan variasi terbaik dari campuran komposisi untuk menghasilkan PBT. Percobaan dilakukan dengan 5 variasi perbandingan lumpur tinja (LT) dan campuran jerami dan sekam padi (JSP) menggunakan aktivator EM4 dan waktu fermentasi selama 14 hari. Variasi yang digunakan adalah 100%LT; 90%LT+10%JSP; 80%LT+20%JSP; 70%LT+30%JSP; dan 60%LT+40%JSP. Analisis regresi linear digunakan untuk mengetahui pengaruh variasi PBT dan komposisi terbaik PBT. Hasil penelitian menunjukkan lumpur tinja sebelum pengolahan memiliki kandungan E. Coli, pH, C-organik, dan Rasio C/N yang sesuai standar mutu sedangkan cake setelah pengolahan memiliki kandungan E.Coli, pH, C-organik, N-total, dan Rasio C/N yang sudah sesuai standar mutu sebagai pupuk organik berdasarkan Kepmentan RI No.261/KPTS/SR.310/M/4/2019. Komposisi terbaik pada penelitian ini yaitu pada variasi 80%LT+20%JSP dengan pH 6.70, C-organik 31.965%, N-total 2.372%, rasio C/N 13.479. Kata kunci: IPLT, lumpur tinja, pupuk bokashi tinja, pengolahan lumpur ABSTRACT Fecal sludge solids (cake) is a byproduct of the fecal sludge treatment plant (FSTP). Banyuroto FSTP produces 33.6 m³/month of dry cake. The fecal cake is generally only dumped in the FSTP area without any further utilization and only becomes waste. One of further effort that can be done is processing it into Fecal Bokashi Fertilizer (FBF). The purpose of this research was to determine the effect of the addition of rice straw and rice husk on Fecal Bokhasi Fertilizer and the best variation of FBT. The experiment was conducted using 5 variations of the ratio of fecal sludge (FS) and a mixture of rice straw and rice husk (RSRH) using an EM4 activator and fermentation time for 14 days. The variations used were 100%FS; 90%FS+10%RSRH; 80%FS+20%RSRH; 70%FS+30%RSRH; and 60%FS+40%RSRH. Linear regression analysis was used to determine the effect of FBF variation and the best FBF composition. The results showed that fecal sludge before treatment had E. Coli, pH, C-organic content, and C/N Ratio that met the quality standards while the cake after treatment had E. Coli, pH, C-organic content, N-total, and C/N Ratio that met the quality standards as organic fertilizer based on the Indonesian Minister of Agriculture Decree No.261/KPTS/SR.310/M/4/2019. The best composition in this research is in the 80%FS + 20%RSRH variation with pH 6.70, C-organic 31.965%, N-total 2.372%, C/N ratio 13.479. Keywords:  FSTP, fecal sludge, fecal bokashi fertilizer, sludge treatment

Berdasarkan hasil klasifikasi tingkat bahaya erosi pada kawasan UB Forest menunjukkan bahwa kelas tingkat bahaya erosi bervariasi dari kelas Sangat Ringan (SR) hingga kelas Sangat Berat (SB). Berdasarkan hasil perhitungan dan klasifikasi, rekomendasi mitigasi atau upaya konservasi tanah yang diberikan memberikan perubahan yang signifikan pada kelas tingkat bahaya erosi setiap satuan lahan. Sehingga, terdapat perubahan signifikan pada nilai erosi potensial dan kelas erosi. Kata kunci: agroforestri, erosi, Kawasan UB Forest ABSTRACT Erosion is the movement of soil from one place to another caused by certain media such as water, wind, and so on. Land use is the main factor of ecosystem change which is very influential compared to other factors such as climate, soil, and topography. This study aims to map the level of erosion hazard and determine recommendations for land conservation technology in the UB Forest area, Malang Regency. The time of research was carried out from May to November 2022. The research area is in the UB Forest area with an area of 554 ha to be precise in Tawangargo Village, Malang Regency. The data processing method is carried out using the Universal Soil Loss Equation (USLE) and the Geographic Information System, namely the overlay method. The Erosion Hazard Level is calculated by comparing the erosion rate of a land unit with the effective soil depth. Land management in the UB Forest area consists of agroforestry land, residential land, and undisturbed shrub land. Based on the classification results of the erosion hazard level in the UB Forest area, it shows that the erosion hazard class varies from Very Light (SR) to Very Severe (SB) classes. Based on the results of calculations and classifications, the mitigation recommendations or soil conservation efforts given to provide a significant change in the class of erosion hazard level for each land unit. Thus, there is a significant change in the potential erosion value and erosion class. Keywords:  agroforestry, erosion, UB Forest Area
