With the development of technology every time, all lines of life are computerized. Likewise, an expert system for determining personality types can help psychologists complete their tasks quickly, precisely and easily. Besides the lack of psychologists in handling cases of personality type analysis is an important note why an expert-based expert determination system is needed. In this study an expert system that was built using a desktop interface can also be based online. Not only when you meet a psychologist you can use it, but you can also use anyone using a PC or smartphone. This research uses the Case Based Reasoning method, where this method is a suitable method in the formulation of new knowledge of the examination of patients in the field of psychology. Referring to a study conducted by Florence Littauer who divided personality types into 4 parts namely Melancholy, Saguinis, Koleris and Plegmatis. It is hoped that this research can help patients and psychologists in analyzing and determining their personality precisely, quickly and easily

The need for lightweight concrete in a variety of applications of modern construction technology is increasing rapidly, the weight and compressive strength of structural lightweight concrete is 1,850 kg / m 3 , and the compressive strength of 17.2 MPa. Many methods are used to obtain lightweight concrete, including in this study conducting experiments to make structural lightweight concrete using iron wood waste, iron wood is made to replace rough aggregate by cutting iron wood into pieces and then coated with leakproof without dropping paint followed by sprinkling sand while the paint is still wet. From the test results the weight and compressive strength at 28 days, concrete weight 1772 kg / m 3 , and compressive strength 17.99 MPa. From the results of strong and compressive strength tests using iron wood waste as a substitute for coarse aggregate, concrete using iron wood aggregate meets the standards as structural lightweight concrete. That the use of iron wood waste as a substitute for coarse aggregate in the way that we make can be an alternative as a substitute for coarse aggregate for making structural lightweight concrete. This material in addition to being used as material for making structural lightweight concrete can also help reduce waste.

Pada jurnal ini kami membuat sebuah system pengendali lampu rumah dengan Mikrokontroler arduino uno R3 menggunakan Android dengan memanfaatkan Fitur speech recognition yang ada pada smartphone android yang dapat dimanfaatkan untuk mengendalikan lampu rumah menggunakan perintah suara., Sehingga untuk menghidupkan atau mematikan lampu rumah tidak lagi dilakukan secara manual, melainkan dengan cara yg lebih mudah yaitu cukup dengan memberikan perintah suara kepada smartphone android yang dihubungkan dengan Arduino melalui Bluetooth. Pengendalian lampu tidak akan bekerja jika smartphone android diluar jarak jangkauan pancaran bluetooth dari bluetooth module karena sambungan bluetooth akan terputus secara otomatis.

Pondasi merupakan suatu konstruksi pada bagian dasar bangunan yang berfungsi meneruskan beban dari struktur bangunan bagian atas ke lapisan tanah. Pembangunan Gedung Control Room di Proyek Pipa Gas Tanjung Batu Kalimantan Timur direncanakan menggunakan pondasi tiang bor ukuran 30 cm dan kedalaman 18 m dibawah muka tanah. Peneliti ingin melakukan perencanaan ulang pondasi tiang bor menggunakan 3 alternatif variasi diameter tiang pancang. Penelitian ini bertujuan mengetahui nilai kapasitas daya dukung dan penurunan. Teknik pengumpulan data yang digunakan adalah data sekunder berupa gambar teknis gedung, data hasil penyelidikan tanah dengan metode sondir dan standar penetration test. Hasil penelitian nilai kapasitas daya dukung ultimit tiang bor eksisting yaitu 434,559 Ton. Nilai kapasitas daya dukung ultimit perencanaan pondasi dengan metode Meyerhoff pada diameter 0,3 yaitu 295,16 Ton, diameter 0,4 yaitu 393,547 Ton dan diameter 0,5 m yaitu 491,933 Ton. Sedangkan dengan metode Aoki & De Alencer pada diameter 0,3 yaitu 285,109 Ton, diameter 0,4 yaitu 406,914 Ton dan diameter 0,5 m yaitu 543,047 Ton. Direkomendasi alternatif desain perencanaan pondasi tiang pancang diameter 0,5 m metode Aoki & De Alencer dengan jumlah 3 tiang dalam 1 kelompok tiang. Hal ini berdasarkan hasil kapasitas dukung kelompok (Qg) lebih besar dari metode Meyerhoff, dari nilai penurunan, nilai penuruan 0,062 m lebih kecil dari nilai penurunan tiang bor pondasi eksisting 0,084 m dan  nilai penurunan tiang dengan  metode Meyerhoff  0,089 m.Keywords: Pondasi Tiang Pancang, Kapasitas Daya Dukung, Penurunan

This research raises the topic of decision support systems using the Moora method. Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) is a multi-objective system that optimizes two or more conflicting attributes simultaneously. This method is applied to solve problems with complex mathematical calculations. The MOORA method has a level of flexibility and ease of understanding in separating the subjective part of an evaluation process into decision weight criteria with several decision-making attributes. This method has a good level of selectivity because it can determine the objectives of conflicting criteria. Where the criteria can be beneficial (benefit) or not profitable (cost). The object of the research is Village-Owned Enterprises in Kampar Regency. In the research process using at least 5 measurement criteria that will be processed in order to obtain a decision. In the Moora method, there are several process steps that must be carried out, including the following: Determining the purpose of identifying the relevant evaluation attributes and inputting the criteria value in an alternative where the value will be processed and the result will be a decision. Create a MOORA Decision Matrix Matrix of Normalization Moora Calculating the value of MOORA's multi-objective optimization Determine the Rank Value from the results of the MOORA calculation The output of this research can be used as input for local governments in making decisions. The results of this study can certainly be a motivation for other BumDes who are not in the best ranking. The results of this study will be more complex when using more complex aspects of the assessment. convenience of interested parties to be able to find our articles.
