Abstract

Penelitian ini bertujuan untuk mengkaji bagaimana keragaman produk memengaruhi nilai pelanggan dan implikasinya terhadap kepuasan konsumen pada Astra Credit Companies (ACC) Cabang Bandung 1 Naripan. Pendekatan penelitian yang digunakan adalah deskriptif verifikatif dengan metode kuantitatif. Sampel diperoleh dari 96 konsumen ACC yang berlokasi di wilayah Bandung Raya menggunakan teknik purposive sampling, dan data dianalisis melalui regresi linear berganda dengan bantuan SPSS versi 21. Hasil penelitian menunjukkan: (1) keragaman produk berpengaruh signifikan dan positif terhadap nilai pelanggan, (2) nilai pelanggan berpengaruh positif terhadap kepuasan konsumen, serta (3) keragaman produk berdampak langsung dan tidak langsung terhadap kepuasan konsumen melalui nilai pelanggan sebagai variabel mediasi. Persamaan regresi yang dihasilkan adalah Ŷ = 28,873 + 0,317X1 + 0,396X2, dengan nilai koefisien determinasi (R²) 0,608. Artinya, 60,8% variasi kepuasan konsumen dijelaskan oleh keragaman produk dan nilai pelanggan. Keterbatasan penelitian ini meliputi cakupan geografis yang terbatas pada satu cabang ACC dan penggunaan metode cross-sectional yang tidak dapat menangkap perubahan preferensi konsumen dari waktu ke waktu.

Abstract

The surfaces of three major tectonic plates the Eurasian Plate, the Indo Australian Plate, and the Pacific Plate intersect in Indonesia. This condition creates a high risk of earthquakes and landslides in areas located at these plate boundaries. The urgency of this research lies in developing a landslide detection device to help communities living in landslide-prone areas remain alert to disasters that may occur at any time. The objective of this study is to develop an Internet of Things (IoT)-based landslide detection device powered by solar energy. This device does not rely on external power sources but utilizes solar energy as its primary power supply. The research employs an experimental method. The steps include problem identification, literature review, system development methodology, design and application development, testing, and analysis of test results.Landslide detection is carried out using vibration sensors to detect ground tremors that may indicate a landslide, tilt sensors to monitor changes in ground inclination, and soil moisture sensors to measure soil humidity. An Arduino microcontroller processes data from the sensors and transmits signals to the warning system, while solar panels generate electrical energy from sunlight. The use of solar cells is optimized by calculating the required energy capacity to operate the sensors, Arduino board, and early warning system.

Abstract

Arabica coffee (Coffea arabica L) is one of Indonesia”s mainstay plants to develop the world's largest coffee producer. The high level of demand for coffee bean products requires the provision of large quantities and quality seeds. Nursery is the first step in coffee cultivation which affects productivity and crop production. The latest biofertilizer innovation is to utilize phosphate solubilizing microorganisms as biological fertilizers. This study aims to determine the effect and interaction of the addition of rhizosphere bacterial suspension and bacterial capsules on Arabica coffee plants. The research design used was a completely randomized design (CRD), consisting of 16 treatments with 2 replications. The first factor was the administration of a rhizosphere bacterial suspension consisting of R0:0 .ml, R1:10 ml:R2:20 ml, R3:30 ml and the second factor was the addition of a bacterial capsule consisting of A0:0 gr, A1:10 gr, A2. :20 g, A3:30 g. Isolates from oil palm soil obtained 14 isolates of rhizosphere bacteria. The best observation of plant height was the R3 treatment (24.55 cm). The observation of the number of leaves was R3 (15,25 cm). for the leaf area parameter the highest number was obtained R3 (25.53 cm). The test results showed that the application of suspension microcapsules and rhizosphere bacteria significantly increased the growth of Arabica coffee (Coffea arabica L)Key words: Rhizosphere bacteria, suspension, microcapsules INTISARIKopi arabica (Coffea arabica L) merupakan salah satu tanaman andalan Indonesia dalam perkembangan penghasil kopi terbesar di dunia Tingginya laju permintaan akan produk-produk biji kopi menuntut penyediaan bibit dalam jumlah besar dan berkualitas. Pembibitan merupakan langkah awal dalam pembudidayaan kopi yang berpengaruh terhadap produktifitas dan produksi tanaman. Inovasi pupuk hayati yang terbaru adalah memanfaatkan mikroganisme pelarut fosfat sebagai biofertilizer. Penelitian ini bertujuan untuk mengetahui pengaruh dan intraksi  penambahan suspensi bakteri rhizosfer dan kapsul bakteri terhadap tanaman kopi arabica.  Rancangan penelitian yang digunakan adalah rancangan acak lengkap ( RAL), terdiri 16 perlakuan dengan 2 ulangan. Faktor pertama adalah pemberian suspensi bakteri rhizosfer yang terdiri dari R0: 0 ml, R1:10 ml: R2:20ml, R3:30 ml dan faktor kedua adalah penambahan kapsul bakteri yang terdiri dari A0: 0 g, A1: 10 g, A2:20 g, A3: 30 g. Isolat dari tanah kelapa sawit diproleh  14 isolat bakteri rhizosfer. Pengamatan tinggi tanaman terbaik adalah perlakuan R3 (24,55 cm) pengamatan jumlah daun adalah A2 (15,25 cm). untuk parameter luas daun angka tertinggi diperoleh R3 (25,53 cm). Hasil pengujian menunjukkan bahwa aplikasi mikrokapsul suspensi dan bakteri rhizosfer secara nyata meningkatkan pertumbuhan tanaman kopi arabica (Coffea arabica L). Kata kunci: Bakteri Rhizosfer, suspensi, mikrokapsul

Abstract

A good library that is able to provide the right information for users,it’s all based on good management as well. The function of managements is so that goals can run in an orderly manner as expected. In this study using field research with a qualitative approach. Techniques used for data collection using observation, interviews and documentation. Meanwhile, the data analysis technique went throught the stages of data reduction, data presentation and verification. In this study, researchers want to examine the MAN Asahan library in management functions, namely planning, organization, actuacting, controlling and evaluation. The result of this study are that the MAN Asahan library has three planning programs, namely long-term, medium-term and short-term programs. Which the task is carried out or carried out in accordance with the duties of the libraries who work in accordance with their respective fields. The shortage of the MAN Asahan library is still the lack of the number of collection and the facilities of the MAN Asahan library are still many that are not suitable for users. Keywords: Library Management, Management Function
