Abstract

Energi angin merupakan salah satu potensi energi terbarukan yang dapat memberikan kontribusiterhadap  kebutuhan  energi  listrik  rumah  tinggal.  Pembangkit  energi  angin bebas  polusi  (CO2)maka pembangkit ini dapat menjawab masalah lingkungan hidup dan ketersediaan sumber energysifatnya dapat diperbaharui (renewable) serta penelitian ini mendukung program pemerintah kotaPadang untuk menjadi lumbung energy terbarukan. Tujuan yang ingin dihasilkan adalah dibuatnyasebuah turbin angin  dalam kapasitas kecil (micro) yang dapat membantu menyuplai listrik sebuahrumah tinggal  dan mampu beroperasi di daerah  kecepatan angin rendah kemudian dapat di set uppada  atap  rumah.  Metodologi  yang  digunakan  untuk  pencapaian  tujuan  adalah  metodaeksperimental  dengan  tahap-tahapan  sebagai  berikut  pengambilan  data  angin  lapangan;  disainturbin angin; pemilihan bahan; pembuatan turbin angin dan pengujian alat.  Kota Padang Sumbartermasuk wilayah yang memiliki kecepatan angin rendah antara 2-6 m/s, maka jenis turbin anginyang cocok adalah  turbin angin tipe savonius karena bisa berputar pada kecepatan angin rendah(low  wind  velocity)    dengan  putaran  awal  (starting)  dapat  terjadi  pada  kecepatan  2m/s  sertakonstruksinya yang sangat sederhana. Disain  turbin yang dibuat adalah berbentuk savonius 2 sududengan  konstruksi  overlap  antara  kedua  sudu  dengan  tujuan  untuk  memanfaatkan  tekanan  anginbalikan dari sudu satu  ke sudu kedua dan sebaliknya sehingga dapat meningkatkan putaran  rotor.Rancangan  turbin  savonius  di  buat  4  tingkat.  Bahan  yang  digunakan  untuk  sudu  turbin  adalahaluminium  dan  jenis  poros  hollow.    Generator  yang  dipakai  adalah  generator  magnet  permanenPanasonic  400watt  yang  dapat  menghasilkan  daya  pada  putaran  rendah  (150  rpm)  ;  Untukmeningkatkan rpm yang sampai ke generator digunakan system transmisi sabuk dan pully denganperbandingan  transmisi  5:1.  Kemudian  tipe  bearing  yang  digunakan  adalah  ball  bearingbearing.Dari hasil pengujian didapat daya maksimum yang dihasilkan adalah 7,7watt dengan putaran rotor340rpm dengan kecepatan angin 5,68m/s dan Cp 0.3

Abstract

Telah dilakukan rancangbangun dan penyuluhan penggunaan instalasi peralatan hidroponik untuk Madrasah Tsanawiyah Negeri 7 (MTsN 7) Kota Padang dalam kegiatan tim Pengabdian Kepada Masyarakat Politeknik Negeri Padang. Tujuan dari kegiatan ini adalah dalam rangka Tridharma perguruan tinggi, dan untuk menciptakan lingkungan yang asri di sekolah tersebut. Untuk mempertahankan keasriannya, maka tim pengabdian PNP bersedia menyumbangkan instalasi hidroponik, agar MTsN mempunyai green house untuk membudidayakan tanaman hias, tanaman obat-obatan, dan sayuran. Kegiatan ini dilakukan mulai dari rancangbangun, setting peralatan, dan penyuluhan cara menggunakannya. Hasil dari kegiatan ini menunjukan antusias yang besar dari sivitas akademika MTsN 7 untuk menciptakan lingkungan yang sehat dan asri. Sehingga Adiwiyata Nasional yang sudah diperoleh dapat dipertahankan.

Abstract

Composite materials is increasingly experiencing an increa- sing trend, the manufacture of composites currently uses a lot of natural fiber reinforcement, Oil Palm Empty Fruit Bunches (OPEFB) fiber is a fiber that comes from oil palm empty fruit bunches waste that grows a lot in Indonesia and has the potential to be used as reinforcement in the manufacture of composites. With natural fiber reinforcement. The manufacture of composites in this study varied the fiber volume fraction by 5%, 15%, and 25%. Many previous studies on composite materials have focused on studying the physical and mechanical properties of composites. Even though damage to a structure or material is not only caused by static loads but also by dynamic loads. Vibration is a dynamic load experienced by material or structure, so it is necessary to determine the dynamic character of composite materials, one of the dynamic characteristics of materials is their natural frequency, the determination of the natural frequency in this study was carried out by using the finite element method in the ANSYS software. The results of the analysis in the form of tensile strength values and modulus of elasticity were obtained from tensile testing and dynamic characters in the form of natural frequencies and vibration modes were obtained from the analysis modal simulation process. From the results of the tensile test, it was found that the composite with a variation of 15% OPEFB fiber volume had the highest tensile strength and modulus of elasticity, as well as the results of the analysis modal simulation, a composite with 15% OPPEFB fiber, had the highest natural frequency value among the other two variations.

Abstract

The closure of TikTok Shop has caused significant polemics, especially regarding the responsibility of e-commerce platforms as well as operational impacts on business and society, such as decreased revenue in the shipping sector, including J&T Express Bandar Lampung. This study aims to analyse the post-closure impact of TikTok Shop on J&T Express' revenue volume, and evaluate it from a sharia perspective. Using a qualitative approach, data were collected through questionnaires, observations, interviews, and documentation in the form of reports and literature. Data collection techniques include field observations and interviews with relevant parties. The results showed that the closure of TikTok Shop had a significant impact, reflected in the decrease in receipt volume at J&T Express Tanjung Gading, where around 70% of revenue came from the platform. From a sharia perspective, the closure of TikTok Shop can be considered appropriate if the platform violates sharia principles, such as justice, responsibility, and consumer protection. If the shutdown contributes to the reduction of exploitation and economic injustice, then the action is in line with sharia values.

Abstract

This study aims to determine the balance of the money and goods markets from an Islamic economic perspective. The research method used is the study of literature from articles, papers, books, and other sources that support the problem under study. The results of this study indicate that Islamic economics states that when prices are fixed, income and interest, or the expected rate of profit, are at a level that balances the commodity market and the money market. The equilibrium level of income and welfare is at the intersection of the IS and LM curves, using the interest rate and the expected rate of return. In Islamic economics, a similar mechanism occurs in the economy that income and the anticipated rate of return lead to the equilibrium level. However, as previously mentioned, changes in income do not directly cause changes in the money market interest rate, which creates a balance between the demand for money and the money supply. Therefore, the interest rate on the interest income panel can only be determined by the IS curve without the LM curve. In other words, the interest rate always appears on the IS curve but can also occur outside the LM curve.
