Pencucian biodiesel merupakan salah satu tahapan dalam proses pembuatan biodiesel. Proses ini bertujuan untuk menghilangkan sisa pengotor yang dapat mengurangi kualitas biodiesel.Pada penelitiandigunakan pencucian dan pemisahan cairan dengan metode mechanical stirring berdasarkan prinsip gravitasi. Umumnya, untuk menentukan batas permukaan antara biodiesel dan air pada pabrik kecil, digunakan penglihatan visual oleh operator. Pada penelitian ini, dibuat seperangkat sensor elektromagnetik untuk menggantikan fungsi operator tersebut.Perangkat sensor bekerja berdasarkan prinsip induktansi bersama pada LVDT (Linear Variable Differential Transformer), sesuai dengan Hukum Faraday dan Hukum Lenz. Pengujian kinerja sensor dilakukan pada miniplant pencucian biodiesel. Sensor juga diuji untuk mendapatkan karakteristik statis dan dinamisnya.Sensor bekerja dengan baik untuk mendeteksi batas permukaan biodiesel dan air ketika cairan dialirkan dengan kecepatan 1,29Ã—10-1m.s-1. Sensor telah diuji dan bekerja baik pada saat digunakan sebagai pemicu PLC (Programmable Logic Controller) pada sistem otomasi pencucian biodiesel.Kata kunci: pencucian biodiesel, otomasi, sensor elektromagnetik, LVDT.

This research aims to determine the effect of concentration and interval of application of kepok banana peel liquid organic fertilizer on the growth and best results of kailan plants (Brassica oleracea). The research was carried out from May to July 2023 on land around Sekaran Village, Wonosari, Klaten with an altitude of ± 71 meters above sea level. Completely Randomized Design (CRD) with two treatments, namely the concentration of kepok banana peel POC and the interval for giving kepok banana peel POC. The concentration treatment consists of 4 levels (P0: 0 ml/L water, P1: 150 ml/L water, P2: 250 ml/L water, P3: 350 ml/L water) and spraying intervals I1 (every 3 days) & I2 (every 6 days). There were 8 experimental units with 4 replications where each experimental unit consisted of 3 sample plants so there were 96 plants. Plant height, number of leaves, root volume, fresh plant weight, and plant consumption weight are the observation parameters. The results showed that concentration had a significant effect on plant height. The P0 concentration gave the best results on kailan plant height. Spraying intervals have a significant effect on the number of leaves, root volume, and fresh plant weight. The I2 spraying interval provides the best results for the growth and yield of kailan plants. The best interaction was also produced by the P3I2 treatment (giving kepok banana peel POC 350 ml/L of water with spraying intervals every 6 days).

This study aims to analyze the implementation of the Village Information System (SID) in Pematang Gajah Village based on Article 86 of Law No. 6 of 2014 concerning Villages, as well as identify inhibiting and supporting factors in its implementation. Pematang Gajah Village has been developing the Village Website since 2022 as a form of SID implementation. This research uses a qualitative approach with data collection techniques in the form of observation, interviews, and documentation. The results show that even though SID has been equipped with hardware, software, and networks, access to information to the public has not been optimal due to uneven socialization. In addition, SID does not contain data on the development of villages and rural areas, and has not been supported by planning information from local governments. The main inhibiting factors include limited understanding of the community and village apparatus towards technology, incomplete socialization, and unstable internet networks. On the other hand, the existence of village websites, budget allocation, and the availability of technological devices are significant supporting factors. The commitment of village officials in gradually increasing the use of SID is also an important capital in system sustainability. This study recommends increasing human resource capacity, equitable distribution of socialization, and strengthening infrastructure support as strategic steps in optimizing SID at the village level.

Penelitian ini bertujuan untuk menganalisis pengaruh sikap investasi dan norma subjektif terhadap minat investasi reksa dana pada mahasiswa penerima beasiswa KSE Universitas Jambi dengan literasi keuangan sebagai variable moderasi. Pendekatan yang digunakan Adalah kuantitatif melalui survey kuesioner, dengan sampel sebanyak 49 mahasiswa penerima beasiswa KSE Universitas Jambi yang secara aktif mendapatkan bantuan dari Yayasan Karya Salemba Empat yaitu dana beasiswa dan program-program pengembangan diri khususnya mengenai literasi keuangan. Analisis data dilakukan dengan menggunakan Partial Least Square - Structural Equation Modeling (PLS-SEM) melalui perangkat lunak SmartPLS 4. Hasil penelitian menunjukkan bahwa norma subjektif berpengaruh positif dan signifikan terhadap minat investasi. Sementara itu, sikap investasi menunjukkan pengaruh positif namun tidak signifikan. Selain itu, literasi keuangan tidak berperan sebagai moderator yang signifikan dalam hubungan kedua variabel independent terhadap minat investasi. Temuan ini mengindikasi bahwa meskipun mahasiswa memiliki pemahaman keuangan yang baik serta pandangan positif mengenai investasi, dorongan dan opini dari lingkungan sosial tetap menjadi faktor utama yang membentuk minat investasi mereka. Dengan demikian dapat disimpulkan bahwa pembentukan minat investasi mahasiswa penerima beasiswa lebih dipengaruhi oleh aspek sosial-psikologis dibandingkan dibandingkan oleh kapasitas pengetahuan keuangan yang dimiliki secara individual.
