Photovoltaic traffic light system is a significant application of renewable energy source. The development of the system is an alternative effort of local authority to reduce expenditure for paying fees to power supplier which the power comes from conventional energy source. Since photovoltaic (PV) modules still have relatively low conversion efficiency, an alternative control of maximum power point tracking (MPPT) method is applied to the traffic light system. MPPT is intended to catch up the maximum power at daytime in order to charge the battery at the maximum rate in which the power from the battery is intended to be used at night time or cloudy day. MPPT is actually a DC-DC converter that can step up or down voltage in order to achieve the maximum power using Pulse Width Modulation (PWM) control. From experiment, we obtained the voltage of operation using MPPT is at 16.454 V, this value has error of 2.6%, if we compared with maximum power point voltage of PV module that is 16.9 V. Based on this result it can be said that this MPPT control works successfully to deliver the power from PV module to battery maximally.

Â As one of alternative sources of renewable energy, wind energy has an excellence prospect in Indonesia, particularly in coastal and hilly areas which have potential wind to generate electricity for residential uses. There is urgent need to locally develop low cost inverter of wind generator system for residential use. Recent developments in power electronic converters and embedded computing allow improvement of power electronic converter devices that enable integration of microcontrollers in its design. In this project, an inverter circuit with suitable control scheme design was developed. The circuit was to be used with a selected topology of Wind Energy Conversion System (WECS) to convert electricity generated by a 500W direct-drive permanent magnet type wind generator which is typical for residential use. From single phase AC output of the generator, a rectifier circuit is designed to convert AC to DC voltage. Then a DC-DC boost converter is used to step up the voltage to a nominal DC voltage suitable for domestic use. The proposed inverter then will convert the DC voltage to sinusoidal AC. The duty cycle of sinusoidal Pulse-Width Modulated (SPWM) signal controlling switches in the inverter was generated by a microcontroller. The lab-scale experimental rig involves simulation of wind generator by running a geared DC motor coupled with 500W wind generator where the prototype circuit was connected at the generator output. The experimental circuit produced single phase 240V sinusoidal AC voltage with frequency of 50Hz. Measured total harmonics distortion (THD) of the voltage across load was 4.0% which is within the limit of 5% as recommended by IEEE Standard 519-1992.

Indonesia as the biggest archipelago country and situated in equator is very vulnerable to the adverse effect of climate change. There are two main categories of efforts to handle the issues in climate change; that are how to mitigate it and how to adapt to the change. One of the main culprits of climate change is the emission of carbon gas due to fossil fuel energy utilization contributing 302 million tonnes CO2 equivalent.President of the Republic of Indonesia in 2009 in the G-20 Meeting, Pittsburgh, USA, and in 2010 in COP 15 UNFCCC, Copenhagen, Denmark issued the national voluntary target to reduce greenhouse gas emission by year 2020 as much as 26% from business-as-usual by national domestic efforts. This emission reduction will further be improved as much as 41% from business-as-usual by international supports. The Government of Indonesia issued a national action plan to reduce greenhouse gases emission which is enforced by Presidential Regulation No. 61/2011. To achieve this target in energy sector,REFF-Burn (Reducing Emission from Fossil Fuel Burning) concept has been proposed by Sumiarso. Based on REFF-Burn Technology Portfolio, reducing emission from fossil-fuel burning is categorized in three different stages, which are pre-combustion, during combustion and post-combustion. In pre-combustion stage, utilization of clean energy is one of the wise choices. The perspective of the clean energy resources and utilization in Indonesia is discussed in this paper.

Industri tekstil punya peran penting dalam perekonomian Indonesia. Akibat dari produk yang cacat perusahaan dapat mengalami kerugian baik kerugian finansial maupun kerugian non-material. Saat ini metode yang digunakan dalam deteksi cacat kain banyak dilakukan secara tradisional atau semi modern, sehingga perlu ada alat dengan inovasi baru yang dapat membantu pendeteksian cacat kain yang dapat digunakan baik untuk pendeteksian cacat kain secara tradisional maupun dengan metode modern. Pada penelitian ini dengan menambahkan sistem mekanik yang dapat menambah kemudahan dan ketelitian pendeteksian cacat. Pada penelitian ini telah dirancang sistem mekanik alat deteksi cacat kain ukuran dimensi 2100 mm x 2000 mm x 2500 mm yang menggunakan penggerak motor AC 1 phase 0,2 kW / ¼ HP, menggunakan gearbox 1:20 dan menggunakan transmisi v-belt untuk menghantar daya putar ke poros dengan kecepatan putar 84 rpm. Rancangan alat deteksi cacat kain ini adalah berbentuk horizontal. Perencanaan transmisi menggunakan v-belt dengan 2 buah puli berdiameter (d1) Ø76,22 mm atau 3 inch dan (d2) Ø88,9 mm atau 3 ½ inch. Bantalan untuk menompang poros bertipe UCF 204 dengan diameter dalam 20 mm. Untuk poros memiliki diameter 30 mm dan panjang 2120 mm menggunakan material AISI 304 dengan putaran poros 84 rpm dan momen putar yang didapat sebesar 139,14 kg.mm. Sistem mekanik deteksi cacat kain ini masih dapat ditingkatkan dengan mengganti poros utama 1 dan poros utama 2 menggunakan poros as padat supaya lebih stabil saat melakukan penggulungan kain, serta mengganti roda pada bagian penompang poros dengan bantalan UCF 204 supaya saat poros sedang berjalan gerakan putarnya stabil.
