Abstract

The policy of renewable energy in Indonesia is expressed in the government regulation no. 79 in 2014 regarding the national energy policy. In the document, renewable energy is targeted to reach 23% in 2025, and a minimum of 31% in 2050. One of the developed renewable energies is biomass which is produced by lamtoro, a plant which has been employed as a mixture in coal at Anggrek steam power plant 2×25 MW Gorontalo. As much of 1% to 5% of lamtoro is added in 1,000 ton of coal per day. The research aims to create a thematic map of the distribution of lamtoro to meet the need of co-firing at Anggrek steam power plant. The result of research shows the total area of field which has been planted with lamtoro is 69,074 ha, scattered in 14 districts. Meanwhile the largest area is Kabila Bone district (22,070 ha), and the smallest area is East Bulango district (0.228 ha). The estimated potential of lamtoro in 14 districts of Bone Bolango regency is about 916,439.86 ton/ha/year.

Abstract

The photovoltaic (PV) panel makes it possible for everyone to produce electricity in their own house. However, the panel is quite a costly investment and requires much consideration to maximize its potential. The roof has variables that would impact electricity generation. The roof of housing in Indonesia was built generally in a complex shape, a combination of gable and hip roofs. This research is conducted to break down factors affecting PV productivity in regard to the roof’s aspects. A computer simulation using Ladybug plugin in Rhinoceros software has been done to achieve the target. Initially, the performance of PV panels on the gable, and hip roof, is analyzed respectively. It is found that the roof’s slope, and orientation, contribute more to the amount of electricity produced than the shape itself. These factors were used to assess the PV potential in several housing models employing simple and complex roof (more than 2 surfaces) construction in the city of Gorontalo. Eventually, a comparison between the estimation of real PV production on housing, and the estimation provided by the simulation is conducted to verify the assessment method. The difference is about 4%, as proof the simulation result is reliable.

Abstract

Drop voltage and power loss at the distribution system of electricity power in the Kotamobagu Area are caused by several factors, a namely far distance of a place that is distributed by electricity power from the source, imbalance load, equipment age, the diameter of the conductor, a distance of powerhouse to the consumer is too far and connection point are caused for technical loss. If it keeps happening, it will decrease the reliability of the electric power system and the distributed quality of the electricity power as well as it can damage the equipment. Therefore, unbalanced loading should be decreased at the phase, and overloading at the network will cause PT PLN (Persero) loss in the Kotamobagu Area. This research aims to analyze voltage drop, percentage of voltage drop, and power loss at every medium voltage feeder of 20 KV that is supplied from PLTD (Steam Power Plant) Kotamobagu until every transformer of distribution at peak load. After it is analyzed, the feeder OK 1, OK 2, OK 3, OK 4, OK 5 obtain the most significant value of drop voltage for 7.221 KV, 1.94 KV, 6.472 KV, 5.04 KV, 4.878 KV, respectively, with a percentage value of 56.507%, 10.742%, 47.841%, 33.689 %,32.257%. All OK happen at powerhouse K-153 (Kobo Besar), K-158 (RS. Monompia Kotamobagu), K-187 (Poopo I), K-201 (Motoboi Kecil), K-287 (Moyag I), respectively. The most significant power loss of 11.890 KW, 4.820 KW, 9.819 KW, 7.311 KW, 10.533 KW happen at powerhouse K-140 (Matali I), K-158 (RS. Monompia Kotamobagu), K-167 (Bilalang V), K-201 (Motoboi Kecil) and K-287 (Moyag I), respectively.

Abstract

The leakage current in the lightning arrester can be used as an indicator to determine the aging level of the arrester. Leakage current is influenced by contaminants in the arrester insulation. This research analyzes the effect of soluble contamination on the internal and external leakage current of lightning arresters as an indicator of arrester degradation. The contaminant used is NaCl (Sodium Chloride) which is dissolved in water, and a ZnO type lighting arrester to determine the level of NaCl contamination, the ESDD (Equivalent Salt Deposit Density) method is used. Lightning arresters that have been contaminated are measured for internal and external leakage currents flowing through the arrester insulation. Based on the experiments that have been carried out, the increase in leakage current in the internal lightning arrester for light, medium and heavy levels of contamination increases by an average of 30% for all test voltages. When compared with the international standard IEC 61643-1 which is determined at 1 mA, the internal leakage current value for light, medium and heavy pollution of the ZnO type Lightning arrester still meets the standard. However, if you use the PLN testing standard, namely 150 µA, the internal leakage current value for light, medium and heavy pollution of the ZnO type Lightning arrester does not meet the standard. Meanwhile, with low and medium contamination, there is no leakage current that occurs on the external part of the Lightning arrester. significant change

Abstract

Di zaman sekarang ini banyak terjadi perkembangan di ilmu pengetahuan di bidang teknologi, salah satunya adalah internet. Dengan adanya internet seseorang dapat bertukar informasi walaupun dengan jarak yang sangat jauh. Di sisi lain beberapa pihak memanfaatkan internet untuk kegiatan yang merugikan pihak lain yaitu pencurian informasi. Berbagai macam teknik digunakan untuk melindunginya, salah satunya dengan digital watermarking. Melalui digital watermarking informasi akan disisipkan ke dalam media digital tanpa mempengaruhi media digital itu sendiri. Beberapa media digial yang dapat digunakan yaitu citra, video, suara, dan teks. Singular Value Decomposition (SVD) merupakan salah satu metode menyisipkan informasi ke dalam media digital. Metode tersebut mendekomposisi citra digital menjadi matriks-matriks persegi. Metode penyisipan informasi dengan SVD ternyata cukup baik dalam mempertahankan citra pada saat proses ekstraksi. Dari hasil percobaan menghasilkan tingkat kemiripan terhadap informasi asli sebesar 0.97200. Hasil ini menunjukkan bahwa implementasi digital watermarking dengan menggunakan metode SVD ternyata menunjukkan kinerja ketahanan yang cukup baik.
