At present, it is difficult to obtain the large size of wood beams, whereas the need to support heavy constructions is high. On the other hand, significant amount of small wood beams and log are available everywhere. Usually, these small wood beams and log are used to non-structural, or even for firewood. The objective of this study is to create a technology to made large structural wood beam by using the small wood beams. This study used 17 test models with the dimensions 40 mm x 90 mm x 1900 mm with the composition, 5 test beams made of whole mahoni (full section-BU), 6 test compiled wood beams made of 2 side layers (BS2BS), and 6 test compiled wood beams of 3 side layers (BS3BS). From those compiled beams made, three of them are made without strengthening, and the other three are given double steel bar strengthening using steel bar with the diamater is 8 mm. The result of this research shows that the load capacity of compiled wood beam increase significantly, i.e. about 87 % for BS2BS and 96% for BS3BS. The stiffness also increses as well, i.e. 79,4% for BS2BS and 90,5% for BS3BS. Therefore, it can proved technically, that it is possible to make big wood beam structure for heavy construction by using smaller dimension beams which has load capacity and performance is near with the whole beam.

Semakin berkembangnya dunia konstruksi para pekerja dituntut untuk semakin kreatif dalam menciptakan inovasi yang baru. Beton merupakan bahan campuran antara semen, agregat kasar, agregat halus, air dan dengan atau tanpa bahan tambahan (admixture) dengan perbandingan tertentu. Penggunaan zat adiktif digunakan dalam upaya peningkatan kualitas beton. Salah satu zat adiktif yang dapat digunakan adalah Sika Plastiment VZ. Sika Plastiment VZ adalah bahan campuran beton yang berbentuk cairan dan sebagai pengurang air yang memberikan efek memperlambat waktu setting pada sebuah adonan beton. Penelitian ini dilakukan untuk mengetahui pengaruh penambahan sika plastiment VZ kedalam bahan campuran beton terhadap kuat tekan beton. Penelitian ini menggunakan sampel berbentuk kubus dengan pembagian 3 sampel untuk beton normal dan 3 sampel lainnya untuk beton dengan penambahan sika palstiment VZ. Benda uji akan dilihat nilai kuat tekannya pada usia 7, 14, dan 28 hari. Hasil penelitian menunjukkan kuat tekan beton pada umur 28 hari menunjukkan jika nilai kuat tekan beton normal yaitu sebesar 40.74 Mpa sedangkan beton dengan bahan tambah sika Plastiment VZ menunjukkan nilai sebesar 70.92 Mpa. Hasil perbandingan keduanya menunjukkan bahwa penambahan sika plastiment VZ memiliki nilai yang lebih tinggi sehingga dengan menambahkan bahan tambah tersebut dalam campuran beton merupakan pilihan yang tepat. Metode grouting merupakan salah satu metode perbaikan beton bocor dalam kondisi beton keropos dibagian sambungan beton yang berguna untuk mengontrol durasi pengerasan.

In this era there are a lot of real estate that stands with attractive prices, facilities and home designs. Real Estate is a land and buildings on it and arranged in an orderly manner. With the rapid growth of society, it is very influential in buying ready-to-live houses that match the criteria and prices they want. However, many people have difficulty in finding a house ready to live in that fits the criteria and price range they want. Therefore, by making the Trend Analysis Application for Ready-to-occupy Houses, it can provide alternative choices to users according to the criteria that buyers want, such as having a garage, garden, building area, having how many floors and so on as well as the price they want. This application was developed using the Least Square Method Trend Analysis Method for datasets of ready-to-occupy houses collected from one housing estate agency. The steps carried out by the researchers started from collecting housing data, then the data was processed using the least square method with R- studio tools and then formulated into the PHP programming language to become a web program. After the web program was successfully built, researchers conducted a survey to determine the level of user satisfaction with the application, which was 77.8% of the 18 survey participants. Based on the presentation, it can be concluded that this research is feasible in providing home recommendations for customers.

The objective of this study is to analyse the impact of stable soybean prices on the productivity of tofu sales, taking into account the mediating variable of industrial growth patterns in tofu firms located in the Tulungagung region. This study employs a quantitative technique as its research method. The data processing in this study uses the smartPLS SEM (Partial Least Squares - Structural Equation Modelling) programme. PLS has the capacity to elucidate the correlation between variables and conduct comprehensive analyses within a single test. In order to test the hypothesis, specifically utilising statistical values, the t-statistic value utilised with an alpha level of 5% is 1.96. Findings of the research: The first hypothesis testing confirmed that the Industrial Development Pattern (Z) really influenced Sales Productivity (Y). The findings of testing the second hypothesis confirm that there is a significant effect of Price Stability (X) on Sales Productivity (Y). The findings of testing the third hypothesis confirm that Price Stability (X) has a significant impact on Sales Productivity (Y). The findings of testing the fourth hypothesis have been validated. The variable X, which represents price stability, has a significant influence on the variable Y, which represents sales productivity, via means of the variable Z, which represents industrial development patterns.
