Abstract

This study aims to analyze the effect of implementing the modular construction method on time and cost efficiency in building construction projects. The technique used in this study is a quantitative approach with data collection through documentation research and interviews with project managers, contractors, and technical teams. The study's results indicate that implementing the modular construction method can save project time by around 20% to 28% and costs by 20% to 24%. These savings are obtained by reducing work time on-site and carrying out several jobs off-site parallel. However, the main challenges are higher initial costs and difficulties adapting modular designs to local conditions. Limited knowledge of this method among contractors is also an obstacle to its implementation. In conclusion, the modular construction method can increase time and cost efficiency in construction projects, but training and increased knowledge are needed for its implementation to be more optimal

Abstract

Rubber plants in East Kalimantan have a great plantation area 123,460 ha consisting of smallholder 95,240 ha, large state 3,630, and large private 25,638 hectares, with a total production of 55,690 tons. The abundant production of rubber plants in East Kalimantan is still utilized in the tree trunk part as raw material for making latex. The rubber seeds as dregs have not been optimally utilized. Rubber seeds are relatively high in nutrition, especially protein content 16.33%, 21.6% fat, and 30.9% carbohydrates. The rubber seeds are less optimally used due to high HCN levels. The possibility diversification of rubber seed is employing the mellorine ice cream. This study aims to analyze the decreasing HCN levels in the boiling time of rubber seeds at (0, 30, 60, 90, and 100 minute) and formulation of rubber seed and water ratio (A1-3:1); (A2-1,5:1); (A3-1:1) by complete randomized design (CRD) on proximate and organoleptic properties. It was found by ANOVA that the proportion of ingredients did not affect the organoleptic color and aroma but significantly swayed the texture and taste. The organoleptic scale is (0-5) and is not within the very likely criteria. The ratio prescription influences mellorine ice cream's physicochemical, where the more rubber seeds used, the higher proximate levels. The best formulation is A1 (3:1), where it gets an organoleptic value of color (4.25), aroma (3.5), texture (4.00), taste (4.40), 0.127% ash content, fat 8.36%, protein 1.57%, carbohydrate 9.08 %, and crude fibre 0.50%. Ultimately, the rubber seeds can be processed into protein source materials for mellorine ice cream, but the protein is still below SNI standards. A modification method is needed to release HCN but does not cause excessive protein denaturation.

Abstract

Sebuah Perkumpulan Programmer dengan nama Perkumpulan Penggiat Programmer Indonesia, selain menjadi wadah berkumpulnya para programmer juga menjadi tempat untuk menjual, dan memasarkan program yang telah ataupun program akan dipesan oleh para programmer atau konsumennya, oleh karena itu dibutuhkan sebuah aplikasi yang dapat mendukung bagaimana konsumen dapat memperoleh kepuasan dalam menggunakan jasa pemrograman di perkumpulan penggiat programmer Indonesia. Yang akan dibentuk adalah rancang bangun dari aplikasi pendukung kepuasan, bagaimana dan faktor apa saja yang nantinya akan menjadi acuan para konsumen untuk memilih menggunakan jasa programmer, sehingga nantinya para programmer dapat meningkatkan kemampuannya agar jasanya dapat digunakan oleh konsumen

Abstract

Perkumpulan Penggiat Programmer Indonesia merupakan perkumpulan yang digunakan untuk memasarkan hasil dari produk program dari para programmer. Lalu agar produk yang dijual bisa laku dipasarkan diperlukan sebuah penelittian untuk mengetahui bagaiaman kepuasan pelanggan yang membeli produk program pada Perkumpulan Penggiat Programmer Indonesai. Dilakukan pengumpulan data dari para konsumen yang aada lalu akan dilakukan analisis dengan menggunakan Partial Least Square – Structural equation Modeling (PLS-SEM). Digunakannya PLS-SEM dikarena uji dengan PLS-SEM yang dapat digunakan pada semua skala data, tidak membutuhkan banyak asumsi dan ukuran sampelnya tidak harus besar. Dari hasil analisis mengunakan metode PLS-SEM didapatkan bahwa Kinerja, Kehandalan, Daya Tahan, Estetika, Kualitas, Membeli Secara Teratur dan Menolak Produk lain tidak signifikan pada model yang dibangun sehingga variabel tersebut dihilangkan dari model karena memiliki nilai loading dibawah 0,5. Dan didapatkan Kualitas produk dan Loyalitas Pelanggan hanya mempengaruhi Kepuasan pelanggan sebesar 2 % dan Loyalitas Pelangganlah yang mempunyai pengaruh besar terhadap Kepuasan Pelanggan sebesar 28%.
