Abstract

Jurnal ini memaparkan hasil penelitian tentang penambahan distributed generation pada sistem distribusi 20kV penyulang Pujon saat terjadi gangguan sympathetic trip. Pembangkit tersebut diantaranya mikrohidro dan wind turbine. Variabel yang diamati adalah pengaruh penambahan distributed generation terhadap perubahan setelan rele gangguan tanah dan perubahan setelan rele saat gangguan sympathetic trip. Bertambahnya pembangkit yang dihubungkan ke sistem akan meningkatkan arus hubung singkat. Pada saat terjadi gangguan satu fasa ke tanah, arus kapasitif pada penyulang sehat dimana terhubung pada bus yang sama akan memberikan sumbangan arus ke titik gangguan. Berubahnya nilai arus gangguan satu fasa ke tanah, menyebabkan perubahan setelan pada rele gangguan tanah baik di sisi incoming maupun outgoing, sehingga diperlukan resetting tms pada rele. Dari hasil analisis, besarnya arus gangguan dapat mempercepat waktu kerja rele. Untuk menghindari gangguan sympathetic trip pada penyulang yang sehat saat terjadi gangguan satu fasa ke tanah, setting arus pada rele gangguan tanah harus melebihi besar arus kapasitif. Kata kunci : distributed generation, gangguan hubung singkat, sympathetic trip, arus kapasitif, DGR.

Abstract

Iron (Fe) is a micro essential needed by plants in small amounts and can be toxic when available in large quantities. This study aimed to evaluate how Fe exposure affects the growth of C. callothyrsus and L. leucocephala seedlings. This study used a completely randomized design with factorial, where the first factor consisted of two levels of seedlings (C. calothyrsus and L. leucocephala), and the second factor consisted of Fe concentration which consisted of 8 levels (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, and 1.75 mM). The results showed that treatment of seedlings species and concentration of Fe was able to significantly affect the growth parameters (height, root length, root dry weight, shoots, and plant dry weight) of seedlings. The control treatment (without Fe) showed the highest growth response compared to those treated with Fe exposure and an increase in Fe concentration was able to reduce all growth parameters in both seedlings. The 0.5 mM Fe concentration reduced all growth parameters of C. calothyrsus drastically, while in L. leucocephala, the Fe 0.75 concentration was able to decrease all growth parameters drastically. The tolerance index of both seedlings decreased with increasing Fe concentration. The rate of photosynthesis did not show a significant difference between treatments, meanwhile, it had a significant effect on chlorophyll affect chlorophyll (a, b, and total chlorophyll) and carotenoid content. The highest Fe content in C. calothyrsus seedlings was at a concentration of 1.5 mM (4.40%), while in L. leucocephala seedlings, the highest Fe content was at 1.7 mM (2.87%).

Abstract

One of the problems with acidic soil is its high aluminum (Al) content, which can cause toxicity to plants. this study was conducted to evaluate the preliminary growth and tolerance of L. leucocephala seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, namely Al concentration, consisting of 5 levels (0, 2, 4, 6, and 8 mM). The evaluation of seedling growth and tolerance assessed included: height, root length, dry weight of roots and shoots, tolerance index, SPAD (Soil Plant Analysis Development) chlorophyll, and photosynthesis rate. The results showed that Al exposure reduced all growth parameters (height, root length, dry weight of roots and shoots) of L. leucocephala seedlings. The tolerance index of L. leucocephala seedlings also decreased significantly (up to 43.68%) with increasing Al concentration. Meanwhile, chlorophyll and photosynthesis rate parameters increased with Al exposure of 2-4 mM, but decreased with higher Al exposure (6-8 mM). The threshold value or sensitivity of L. leucocephala seedlings to Al exposure was less than two mM. The L. leucocephala species can also serve as an alternative for land rehabilitation with high Al content as post-coal mining land.

Abstract

Aluminum (Al) is one of the problems and is a factor inhibiting plant growth on soils with acidic pH. This study aims to examine the growth response of Eucalyptus pellita and Eucalypus Deglupta seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, where the Al concentration consisted of 5 levels, namely: 0 mM (control), 2 mM, 4 mM, 6 mM, and 8 mM with 3 repetitions each and each repetition consisted of 3 units of the plant. The results showed that Al treatment had a significant effect on the growth parameters of both plant types, except for the root dry weight parameter for E. deglupta. Increasing the Al concentration can reduce almost all growth parameters. The 4 mM Al concentration was able to increase the height growth, plant dry weight (roots and shoots), and tolerance index for the E. pellita species, while the Al 2 mM concentration was able to increase the root growth of E. deglupta plants. Almost all growth parameters for E. pellita species were higher than that of E. deglupta, except for the SPAD chlorophyll index. The concentrations of 6 mM and 8 mM were toxic to E. pellita and E. deglupta.
