Abstract

Kerusakan lahan gambut disebabkan oleh berbagai faktor, diantaranya pemanfaatan dengan membuat saluran-saluran drainase yang berlebihan, sehingga lahan gambut basah menjadi kering, dan rawan untuk kejadian kebakaran berulang. Pemerintah Indonesia membentuk Badan Restorasi Gambut yang bertujuan untuk percepatan pemulihan kawasan dan pengembalian fungsi hidrologis gambut. Kegiatan Pengembangan masyarakat yang dilakukan bertujuan untuk meningkatkan dan mengembangkan pendapatan masyarakat melalui usahatani masyarakat di kawasan target prioritas restorasi gambut. Hasil kegiatan menunjukkan bahwa petani di Kampung Misik mengusahakan lahan dengan tidak melakukan pembakaran. Kegiatan pertanian adalah sayur, buah-buahan, yaitu: jagung manis, melon, gambas, pare, bawang daun, dan cabe. Luas lahan yang diusahakan oleh petani rata-rata 550m2, dengan rata-rata pendapatan per periode tanam sebesar Rp. 3.786.417,- atau Rp. 1.262.139,- per bulan, dengan rasio penerimaan dan biaya (R/C) yang paling baik adalah usahatani tanaman pare dengan nilai 7, sedangkan yang terkecil adalah jagung manis, terung, dan melon dengan nilai 3. Penguatan usahatani masyarakat melalui suntikan modal usaha dapat digunakan sebagai modal usahatani berikutnya. Beberapa petani dapat mengembangkan usahataninya dalam bentuk luasan tanam ataupun ragam usahataninya. Pembentukan modal usahatani saat ini telah dimulai dengan adanya kewajiban iuran setiap bulan yang disampaikan dalam pertemuan rutin setiap bulan.

Abstract

Pengelolaan lahan gambut berkelanjutan diupayakan dengan restorasi lahan gambut untuk mempercepat pemulihan fungsi ekosistem rawa gambut pada satu kesatuan hidrologis gambut dan untuk perlindungan dan pengaturan tata air alaminya. Kajian ini mengobservasi potensi skema perhutanan sosial sebagai salah satu strategi merestorasi lahan gambut dengan mencermati kebijakan praktik (lokal) di masyarakat, potensi keekonomian dan kawasan yang berpotensi. Kajian ini berdasarkan desk study, pencermatan terhadap hasil penelitian mitra penelitian Deputi Penelitian dan Pengembangan Badan Restorasi Gambut, khususnya terkait paludikultur yang dikategorikan sebagai studi kasus yang memungkinkan bagi perhutanan sosial, juga dilaksanakan observasi lapangan untuk pendalaman studi kasus. Kajian ini memdapatkan gambaran bahwa PP No. 57/2016 dapat mendukung sinergi dengan konsep perhutanan sosial. Beberapa praktik (lokal) memungkinkan partisipasi masyarakat dalam pengelolaan lahan gambut dengan mendapatkan keuntunan dari berbagai jasa ekosistem (pada studi kasus di Sungai Beras, Tanjung Jabung Timur, Jambi), paludikultur yang dapat merevegetasi dan berintegrasi dengan pengelolaan hutan terdekat (studi kasus revegetasi Hutan Lindung Londerang, Tanjung Jabung Timur, Jambi), menurunkan konflik sosial (studi kasus di Kesatuan Pengeloaan Hutan Lindung Gambut Beram Itam, Tanjung Jabung Barat), Jambi); sementara di Kepulauan Meranti, riset aksi agroforestry mendapatkan bahwa kesadaran masyarakat tentang praktik bijak pengelolaan produk kayu dan non kayu berpotensi untuk diterapkan dalam praktik perhutanan sosial. Sementara, restorasi gambut terintegrasi dimungkinkan dengan mengadaptasikan konsep perhutanan sosial pada kawasan gambut berfungsi budidaya. Hal ini dapat meningkatkan manfaat bagi masyarakat baik keekonomian dari pertanian dan jasa ekosistem lainnya yang disedikakan oleh model pengelolaan kehutanan; dan memfasilitasi perubahan bertahap bagi reforestai di lahan gambut. Perhutanan sosial di lahan gambut memiliki potensi menjadi tradeoff antara kepentingan sosial, nilai ekonomi, dan lingkungan.Potential Implementation of Social Forestry in Engaging Community Participation in Restoring PeatlandsAbstractSustainable peatland management of tropical peatland is efforted by restoration to accelerate restoring peatland ecosystem function within an area of Peatland Hydrological Unit (PHU), and to preserve water and regulate water system in a natural way. This study observes the possibility of social forestry scheme as a strategy to restore peatlands by discussing regulations, local practices of communities, potential economic benefits, and potential areas. Our observation is based on desk study and reviewing research outputsof Deputy Research and Development of Peat Restoration Agency particularly related paludiculture, we classified the case study which social-forestry enabler, as well as field observation. This shows that PP No. 57/2016 enables peat restoration operationalizing withsocial forestry concepts. Some (local) practices enable community participation in managing peatlands by gaining benefits from several ecosystem services (case study in Sungai Beras, East Tanjung Jabung, Jambi), integrating with other forestry management nearby (case study in Protected Peat Forest Londerang, East Tanjung Jabung, Jambi), decreasing social conflict (case study in Beram Itam, West Tanjung Jabung, Jambi); while in Kepulauan Meranti, action research in agroforestry elicited that the awareness about the wise practices in managing timber product and non timber forest product is potential for social forestry practices. Meanwhile, integrated peat restoration is possible by adapting the concept of forestry to cultivation function of peatlands. This practice will increase the benefit to the communities from economic benefits from agriculture and ecosystem services provided by forestry management model in a longer period; and facilitate a stepwise change towards reforestation. Social forestry in peatland has the potential to be a trade-off between social interests, economic values, and environment.

Abstract

Power losses that occur in transmission lines result in various impacts that arise, including a decrease in voltage on the transmission line, low power factor that occurs. To reduce the occurrence of power losses that occur in transmission lines, capacitors are installed. In installing capacitors, attention must be paid to the channels that use them, the location of the capacitor and the size of the capacitor used. This is done so that the placement of the capacitor can be optimal in reducing the power losses that occur.This analysis is applied using the fast de-coupling method on a 20 kV power system.with applicationMatlab 7.0, after analysisknowntotal P loss – loss = 76,025 kW, and Q loss = 216,077 kVAR. After optimization by adding a capacitor to bus 2, it was found that the power losses were smaller, namely total P loss – loss = 46,438 kW and Q loss = 125,307 kVAR.

Abstract

The cooling tower circulating pump circulates cooling water throughout the cooling system by controlling the rotation of the circulating pump using an inverter. The method in this research uses quantitative methods. The research aims to analyze two circulating pump units with and without inverter. The results of one year of research on circulation pumps without inverter consumed 48,180 kWh of electrical energy and circulation pumps with inverter consumed 31,083.4 kWh of electrical energy, the resulting electrical energy savings was 17,096.6 kWh at a cost of IDR 19,058,263.9. Using an inverter can save electric energy consumption because the speed of the circulation pump can be adjusted, which causes the output voltage to vary and not always remain constant at the maximum value, so the electric energy consumption is lower.

Abstract

The coal feeder motor is a three-phase induction motor whose speed is regulated by the Variable Speed Drive (VSD). The coal feeder motor functions as a medium for distributing coal fuel to the combustion chamber in the boiler which aims for the combustion process in heating water on the pipe wall (wall tube) which will be used as steam to drive the turbine. Before supplying coal, first pay attention to the amount of coal entering the coal feeder, because it will affect the coal flow and motor performance. The more coal that enters the coal feeder, the greater the coal flow, just as the high speed of the motor will increase the flow of coal entering the furnace. From the research results, the calculation of the change in motor speed to the torque of the coal feeder motor at a speed of 115.2 rpm obtained a torque of 7.88 Nm, at a speed of 144 rpm obtained a torque of 6.68 Nm, at a speed of 230.4 rpm obtained a torque of 5.33 Nm and at a speed of 288 rpm obtained a torque of 4.48 Nm%. at a speed of 115.2 rpm an efficiency of 31.05% was obtained, at a speed of 144 rpm an efficiency of 29.55% was obtained.

Abstract

Electricity is a very important need, especially in the field of information technology development, educational facilities and households. The application of alternative electrical energy sources as backup energy by utilizing DC (direct current) energy sources from batteries (accu) which are converted through circuit stages so that they can be used as AC (Alternating current) backup energy sources. PLN electricity used to charge the battery (charge) through a step down transformer to 24Vac then rectified through a rectifier circuit in the form of a bridge rectifier aims to rectify the AC voltage to a DC voltage of 24Vdc to charge the 24Vdc battery. This automatic charger test aims to obtain the performance of the circuit that will cut off the charging current at a voltage of 13.5V on a 12V battery with a capacity of 5AH automatically when the battery is fully charged. Where the battery input comes from the rectifier output of 13.5V and the battery output will be used as input from the inverter. Before the automatic Charger circuit is connected to the battery, the battery input voltage is set at 11.5Vdc. Charging the charger produces a voltage of 13.5 volts with a maximum charging current of 1.17Amperes with a charger time of 2.5 hours, the charging process from a voltage of 11.5 Volts increases to 13.5 Volts. The temperature of the battery when charging must also be monitored so that there is no excessive heat that can damage the battery cells which reduces the life of the battery.

Abstract

1 Phase AC motors are often used as drivers on equipment with full speed or relatively constant speed, especially in industry or households. Power consumption on 1 Phase AC motors with constant speed is greater, therefore it can cause waste in the use of electrical energy. To overcome this problem, a way is needed to save electrical energy, especially in the operation of 1 Phase AC motors. One effort to save on electrical energy consumption, especially in the use or operation of 1 Phase AC motors is by using a power converter in the form of an inverter. From the results of the study that has been obtained, the use of 1 Phase AC Motors when operated using two motors without being connected to an inverter, the power measured on the measuring instrument reaches 0.796 kW with electrical energy of 1.194 kWh. If the 1 Phase AC Motor is operated using an Inverter, the power measured on the measuring instrument reaches 0.408 kW with electrical energy of 0.612 kWh. The comparison of the use of electrical energy of 1 Phase AC motors using an inverter is lower than the use of electrical energy of 1 Phase AC motors without using an inverter, which can be used as savings in electrical energy in monthly usage.
