Abstract

The phenomenon of a total solar eclipse (total solar eclipse) can only occur within a period of 100 years, until now, even the natural phenomena related research is very interesting to do mainly related to metabolic processes that occur in green plants or high level. In the study, the behavior of Mimosa pudica plant will be measured by using a sensor device. The sensor device with PISA algorithm will monitor environmental factors such as light intensity, temperature, humidity and atmospheric pressure at the time of a solar eclipse total. In this case, changes in the behavior of Mimosa pudica plant to sunlight will be validated by using a digital camera to obtain information leaf movement. The results of this study the sun upon the occurrence of a total eclipse, the temperature conditions around the plant Mimosa pudica average 26oC. The movement of the leaves of Mimosa pudica move to close when the temperature of 25° C at 07. 43 pm. Leaves of Mimosa pudica reopened at 7:52 pm when the temperature is more than 27oC. sunlight at 7:24 o'clock pm at the time of the total solar eclipse of 1800 Lux. From the results of the measurements, light intensity sensor node at 07:25 - 07.29 pm downhill until the condition is 0 Lux, which means the condition is very dark with no light around the plant. From the results of measurements made at 07:39 hours GMT where the changes in air temperature around the leaf on the value of 25.59°C and light intensity levels 1729.4 Lux, Mimosa pudica leaves start to close. By the time the sun began to shine the light level the surface of the leaves, and the air temperature increases, the leaves of Mimosa pudica made the decision to seal the surface of the leaf, after 3 minutes the leaves will open again because there is no stimulus temperature and light. This research also analyzed the data with modeling RGB on the surface of the leaves to get the data chlorophyll Before the solar eclipse average picture chlorophyll on the leaf surface is 0.68149. By the time the sun shone on the condition of 3% on average 0.15494 prior to the occurrence of a total solar eclipse. On the condition of the leaves cover the average - average 0.29555, and after a solar eclipse passing and riding conditions and uneven irradiation, the average value of chlorophyll on the leaf surface is 0.54612.

Abstract

Peatland is a unique ecosystem with water saturation; peatland regulates hydrological processes, climate, environmental conditions, and biodiversity. Poor management practises regarding peatlands can lead to land degradation, and peatland degradation typically has negative effects. Recent tropical peatland research in Indonesia has predominantly revolved around the examination of the ecological consequences resulting from various management approaches. There is little study on farmers' agroforestry efforts to preserve and restore degraded peatlands. A comprehensive examination was undertaken to assess a range of facts, information, and scholarly articles pertaining to the practise of agroforestry on peatlands in Indonesia. The primary incentive for farmers to adopt agroforestry systems originates from their recognition of the impending scarcity of trees. By integrating intercrops with cultivated trees, farmers anticipate generating adequate money to fulfil their family's economic requirements. Farmers who choose intensive intercropping practises are motivated by market demand, whereas farmers who do not adopt this approach tend to favour crops that necessitate less rigorous management. The provision of governmental assistance holds significant importance, and there is a pressing need for additional guidance and support. The potential for rehabilitating degraded peatlands by the implementation of agroforestry practises of native tree species is considerable. Their growth patterns contribute to enhanced vegetative coverage, resulting in heightened moisture levels, reduced temperatures, diminished fire hazards, and improved peat soil quality. The relationship between the physiography of the land and the depth of the peat is directly associated with the patterns and components of agroforestry in peatland environments.

Abstract

Salah satu ciri gambut adalah rentan terbakar pada musim kemarau. Jika gambut terbakar maka akan sulit untuk dipadamkan karena material gambut terdiri dari bahan organik yang menjadi bahan bakar ketika kering. Kebakaran mengakibatkan perubahan sifat fisik tanah akibat hilangnya bahan organik tanah akibat panasnya api sehingga merusak struktur tanah, meningkatkan bulk density dan menurunkan porositas tanah. Peningkatan bulk density dapat mengakibatkan peningkatan tingkat kematangan gambut sehingga mempercepat penurunan permukaan tanah dan pelepasan CO2. Bulk density merupakan indikasi kepadatan tanah, semakin padat tanah maka semakin tinggi pula bulk density yang berarti semakin sulit air untuk melewatinya. Penelitian ini bertujuan untuk mengetahui persentase hari tergenang yang ditunjukkan dengan nilai tinggi muka air lebih dari 0 m dan bulk density pada berbagai tutupan lahan yaitu hutan dan lahan terbakar di Provinsi Kalimantan Tengah. Hasil penelitian menunjukkan bahwa nilai bulk density dipengaruhi oleh faktor tinggi muka air dan faktor kebakaran. Bulk density pada lokasi hutan KHDTK Tumbang Nusa sebesar 0,175 g cm-3 dengan persentase hari tergenang sebesar 0%, hutan Taman Nasional Sebangau mempunyai nilai bulk density sebesar 0,054 g cm-3 dengan persentase hari tergenang sebesar 14,30%, areal bekas terbakar bagian selatan mempunyai nilai bulk density sebesar 0,076 g cm-3 dengan persentase hari tergenang sebesar 0% dan bekas terbakar dari Taman Nasional Sebangau 0,082 g cm-3 dengan persentase hari tergenang sebesar 50,90%.
