Published: August 2020

Lahan gambut mencakup 3% dari daratan bumi dan menyimpan sebagian besar
sumber daya karbon dunia yang kurang lebih setara dengan 1/3 dari karbon dalam tanah global. Selama kurun waktu 12 tahun terjadi penurunan kandungan karbon sebesar 438 juta ton di provinsi Jambi yang disebabkan oleh perubahan penggunaan lahan, pembukaan lahan, sisem drainase dan dan kebakaran lahan gambut. Adanya penurunan jumlah cadangan karbon tersebut mengindikasikan karbon yang semula berada pada lahan gambut telah teremisi ke atmosfer sehingga berdampak pada pemanasan global. Hutan Lindung Gambung (HLG) Londerang adalah salah satu ekosistem hutan gambut tropis yang masih tersisa di Sumatera bagian tengah dengan kondisi sangat kritis akibat peristiwa kebakaran hutan, dengan demikian fungsi ekologinya tidak lagi berjalan optimal. Penelitian ini bertujuan untuk memprediksi jumlah cadangan karbon bawah permukaan, mengetahui potensi emisi karbon serta memberikan arahan pengelolaan karbon di areal hutan lindung gambut Londerang, Kabupaten Tanjung Jabung Timur. Pelaksanaan penelitian ini menggunakan Metode Survei. Penentuan titik-titik pengamatan dibuat secara transek yaitu tegak lurus terhadap tanggul sungai dengan grid 500 x 1000 m sehingga diperoleh 38 titik pengamatan pada lokasi penelitian seluas 19.00 Ha. Jumlah total cadangan karbon bawah permukaan di areal penelitian seluas 19.00 Ha adalah 6.654.152,19 ton atau 3502 ton/Ha. Potensi emisi karbon yang dihasilkan akibat hilangnya gambut setebal 10 cm karena terbakar pada lahan penelitian seluas 1900 Ha adalah sebesar 12367,1 ton C atau 6,509 ton/Ha. Upaya-upaya yang perlu dilakukan untuk menekan laju emisi karbon dan mempertahankan fungsi lahan gambut sebagai pengikat karbon dalam jumlah yang besar adalah dengan melakukan restorasi hidrologi dan revegetasi.

Observations about the impact of environmental parameters and time, on fortified vegetable oil, using typical commercial grade linear low density polyethylene (LLDPE) packaging during typical shelf-life conditions, are minimal. We tested the long-term (12 months) impact of temperature and illuminance (light: 100 to 150 lux and darkness <1 lux) on refined bleached deodorized palm olein (RBDPOL), fortified with vitamin A, and without antioxidant. Results showed degradation of fortified RBDPOL with 70 ppm vitamin A was approximately 19% at 18-22oC in Light, 18% at 18-22oC in Darkness, 38% at 32-33oC in light and 24% 32-33oC in darkness. A similar trend was observed at 45 ppm vitamin A. Exposure to both heat and light impacted vitamin A degradation, but was primarily attributed to prolonged exposure at elevated temperature, irrespective of the packaging material. This short study validates extensive research by Silalahi et al., (2017), doi:10.1111/ijfs.13462 on the impact of environmental effects of fortified vegetable frying oil, during extensive storage life periods.

This study aims (1) to assess the factors of production and their effects on soybean production, and to investigate the ability of input levels, such as area and others to explain the response of production; and (2). assess the response of farmer supply to input prices, receipt of gross expectations, from related variables, and other exogenous variables.
This research was conducted in 2017 in East Tanjab Regency. The method of analysis in its application is sorted based on the research objectives namely the Empirical Model of the Response Response Function. From the research, the results obtained from the soybean supply response model are strongly influenced by many factors. Among internal and external factors such as soybean prices, use of inputs, and seasons, which are quite relevant where soybean production increases because soybean prices increase. It also added that soybean production decreases when the input variables used are not in accordance with the provisions. As expected it was also found that the harvested area was also a significant determinant of crops. Furthermore it was found that soybean production increased during the rainy season. This finding is consistent with the fact that water availability is an important factor for soybean plants. The analysis also explained that soybean farmers in tidal land in the study area responded to the change in the use of efficient inputs. Supply of output is a response to soybean production. On input requests, many are sensitive to the use of labor, maintenance / harvesting labor. The elasticity of production obtained complements the part of the data base needed to evaluate the policy implications of using alternative inputs from soybean supply and input demand.
