The classification of the aroma pattern of pork oil and canola oil on the chemometric-based electronic nose has been classified. The electronic nose used is a series of chemical sensors combined in parallel. Sensors are made of semiconductor material that can detect changes in gas in the air. Each sample measured by an electronic nose provides output in the form of different voltages on each sensor. The data processing method used is Linear Discriminant Analysis (LDA) which is able to classify based on patterns. The samples used were canola oil, pork oil and a mixture of pork oil and canola oil with a percentage of 50%: 50%. The results of the classification of electronic nose patterns with samples of pork oil and canola oil show that each sample is fairly well clustered with the value of the first disk function is 99.9% and the second discriminant function value is 0.1%.

Distilled water in the laboratory is highly important since it is a basic requirement in the lab work and/or research. The large use of distilled water in the Faculty of Mathematics and Natural Sciences University of Lambung Mangkurat (FMIPA ULM) obliged to depend on its own by providing the equipment to produce distilled water. The efficiency of water is low during producing one liter distilled water due to 35 liters is needed. Several studies have conducted focusing on the energy efficiency and the use of alternative energy in the distilled water production. Efficiency is not only limited on the heating energy sources, but also the cooling component. One of the attempts is modifying the cooling water circulation in the distillation equipment. It aimed that the cooling water is not wasted but is returned to the circuit. In this study, a cooling water circulation modification was carried out by adding a radiator set, submersible pump and storage tank. The distilled water produced from this circuit will be compared with distilled water from distillation equipment without modification. The parameters compared which are: temperature, volume, electrical conductivity and pH. Our research results show that the modified distillation equipment series is feasible to apply since the electrical conductivity of the resulting distilled water is lower than before modification process and also the sediment attached to the boiler wall is formed slower than the distillation equipment without modification. With the need for a lower volume of raw water, a series of modified distillation equipment is also suitable for use in the dry season or during water distribution is not smooth.

Technological processes for modification of materials, deposition, and prevented fumes in the pyrolysis processes are used gases materials in the medium with vacuum pressure or atmospheric air pressure. Therefore, it is essential to understand heat flow transport for designing an eﬃcient reactor or find the substrate's excellent position in the reactor or furnace for growing materials. We evaluated the energy transfer phenomena in the form of temperature distribution and heat flow for various heating sources for the gases and solid materials by Gauss-Seidel equation. The thermal conductivity coefficient (k), number of heating sources, and position of heating sources show an essential parameter for transmitting the distribution of the heat. For high k value shows efficiently for heat transfer at low temperature due to the atom's position close each other. The heat also affects to the phonon and lattice vibration like a wave which successfully shows these phenomena in this study.

Climatologically, Aceh is influenced by global, regional, and local phenomena strongly influenced by the hilly mountain topography. Aceh is also surrounded by Indian Ocean in the west, Malacca Strait in the east and Andaman Sea in the north that making climate conditions more varied. The old season zone is not compatible to explain this condition. This paper makes an updated analysis by combining the observational and satellite data for rainfall activity explanation. We use k-means clustering based on the analysis of blending data between observation data and satellite imaging that produces more specific and updated season zone (ZOM). The clusters obtained are newly season zones that provide more specific mapping for dry and rainy season information. The updated season zone of 15 ZOM clusters based on k-means can figure a clear variation that means the accuracy of difference rainfall value can be more precise. From this research, the updated season zone can provide effective planning about strengthened from various government sectors in the future that can give a better policy to the public community.

Activated carbon is a carbon with an amorphous structure arranged in a parallel hexagonal ring. In this research, activated carbon has been synthesized from sago waste. The purpose of this research was to synthesize activated carbon with ZnCl2 activator and investigate the effect of ZnCl2 activator concentration on the characteristics of activated carbon. Synthesis of activated carbon was carried out with the following stages: dehydration, carbonization, silica extraction with NaOH and ZnCl2 activation with variations in concentrations of 5, 15 and 20%. The characterization of activated carbon was carried out by analyzing the crystal structure and morphology, which was conducted using a scanning electron microscope and x-ray diffractometer. The characterization results showed that the best activated carbon was synthesized from 15% ZnCl2 activator due to its amorphous structure with a relatively small pore size of 2 µm.

ABSTRAK - Peningkatan konsumsi energi listrik tidak diimbangi dengan ketersediaan sumber energi fosil yang selama ini digunakan sebagai bahan bakar oleh mayoritas pembangkit listrik di Indonesia, sehingga memunculkan permasalahan keamanan ketersediaan energi listrik. Salah satu cara mengatasi permasalahan tersebut adalah dengan pemanfaatan Energi Baru Terbarukan dari limbah pertanian yang digunakan sebagai bahan bakar Pembangkit Listrik Tenaga Biomassa (PLTBm). Pulau Sumbawa salah satu daerah yang memiliki potensi biomassa limbah tongkol jagung yang melimpah yang dapat dimanfaatkan sebagai bahan bakar PLTBm skala kecil maupun skala besar dengan cara pembakaran langsung. Penelitian ini menggunakan data dari Dinas Pertanian dan Perkebunan NTB tahun 2018 sebagai referensi untuk mengetahui potensi limbah tongkol jagung, dikarenakan jagung di pulau Sumbawa dijual pipilan, maka tongkol jagung hanya dibuang begitu saja. Oleh karena itu diperlukan perencanaan membangun PLTBm untuk memanfaatkan potensi tongkol jagung yang ada di pulau Sumbawa tersebut. Penelitian ini merancang desain struktur sebuah PLTBm skala kecil bahan bakar tongkol jagung menggunakan software Autodesk Inventor 2017. Hasil rancangan desain struktur PLTBm pada penelitian ini sudah memenuhi standar keamanan untuk dilakukan pembangunan PLTBm secara riil berdasarkan hasil simulasi Computer Aided Engineering (CAE) yang telah dilakukan menggunakan Finite Element Analysis (FEA), dari hasil simulasi didapatkan nilai safety factor minimum adalah 1,26 ul dan maximum 15 ul.KATA KUNCI: Autodesk Inventor 2017; Desain PLTBm; FEA; Simulasi CAE ABSTRACT - The increase in electricity consumption is not matched by the availability of fossil energy sources that have been used as fuel by the majority of power plants in Indonesia, which raises the security problem of the availability of electrical energy. One of the ways to overcome this problem is by utilizing New and Renewable Energy from agricultural waste which is used as fuel for Biomass Power Plant (PLTBm). Sumbawa Island is an area that has the potential for abundant corn cobs biomass which can be used as fuel for small and large scale PLTBm by direct combustion. This study uses data from the NTB Agriculture and Plantation Office in 2018 as a reference to determine the potential for corn cobs waste, because corn on the island of Sumbawa is sold as pipilan, so corn cobs are just thrown away. Therefore a plan is needed to build a PLTBm to take advantage of the potential of the corn cobs on the island of Sumbawa. This study designed the structural design of a small-scale PLTBm for corn cobs using Autodesk Inventor 2017 software. The results of the PLTBm structural design in this study have met the safety standards for real PLTBm construction based on the results of Computer Aided Engineering (CAE) simulations that have been done Finite Element Analysis (FEA), from the simulation results obtained the minimum safety factor value is 1.26 ul and a maximum of 15 ulKEYWORDS: Autodesk Inventor 2017; CAE Simulation; FEA; PLTBm Design
