Abstract

Some previous studies suggested pros and cons regarding the correlation between investment and economic growth. The study is to determined if investment in Indonesia has a positive influence on the economic growth in Indonesia. This study uses a Vector Auto Regression/ VAR. Variables used in this study include economic growth, investment growth, export growth and import growth. The calculations show that investment growth and export growth has a positive effect on economic growth, whereas import growth has a negative effect on economic growth in Indonesia. These results indicate that the driver of economic growth is investment and exports. Thus, the government must create a climate to increase the role of investment in economic growth.   Beberapa kajian terdahulu menyatakan adanya pro dan kontra mengenai korelasi antara investasi dengan pertumbuhan ekonomi. Hipotesis yang ingin dibuktikan dalam kajian ini adalah investasi di Indonesia memiliki pengaruh yang positif dengan pertumbuhan ekonomi di Indonesia. Penelitian ini menggunakan metode Vector Auto Regression (VAR). Variabel yang digunakan dalam penelitian ini antara lain pertumbuhan ekonomi, pertumbuhan investasi, pertumbuhan ekspor dan pertumbuhan impor. Hasil perhitungan menunjukkan bahwa pertumbuhan investasi dan pertumbuhan ekspor memiliki pengaruh positif terhadap pertumbuhan ekonomi, sebaliknya pertumbuhan impor memiliki pengaruh negative terhadap pertumbuhan ekonomi di Indonesia. Hasil ini mengindikasikan bahwa pendorong pertumbuhan ekonomi adalah investasi dan ekspor. Dengan demikian pemerintah harus menciptakan iklim untuk meningkatkan peran investasi dalam pertumbuhan ekonomi.

In addition, some places of worship have historical values ​​that need to be known by many people. For example, the oldest mosque in Papua and West Papua is in Fakfak Regency. Regarding to this problem, an information system was created that can display information about places of worship in Fakfak. The method used in this research is a waterfall process model. This application is tested using black box methods and questionnaires. The result reveals that an Android-based application of the Geographic Information System for Places of Worship in Fakfak Regency can help to make it easier for tourists and the Fakfak community to find and obtain information related to places of worship in Fakfak. The results of the black box test state that the functions of the application are running well. The questionnaire test gave results from questions filled out by 20 respondents who stated that the application of the Geographic Information System for Places of Worship was suitable to use by the Fakfak community in obtaining information about places of worship and information on religious history and making it easier for users to find the location of the worship places they wanted to visit.

Abstract

The textile industry is growing very rapidly, the dye waste produced if thrown away can damage the environment. The dye waste can be degraded by electrocoagulation process or using photocatalyst. Electrocoagulation is a process of destabilizing a suspension so that it forms or flocs that are easily separated with the help of an electric current. Titania nanotube arrays are a commonly used photocatalyst. This catalyst is activated when exposed to light. The present study has investigated the impact of pH on the integration of electrocoagulation and photocatalysis processes. From the research conducted, it was found that the best waste degradation electrocoagulation process was at pH 10 with a decrease in dye reduction of 67.72%, for the photocatalyst degradation process the best results were at pH 10 with a decrease in dye reduction of 30.76%. The optimal conditions for the combination of photocatalysis and electrocoagulation were obtained at pH 10 with a reduction in dye waste of 71.6%.

Abstract

Inaportnet adalah platform internet yang berpusat pada standar operasional pelabuhan untuk mengelola kegiatan di pelabuhan dan untuk memberikan perizinan seperti surat persetujuan berlayar. Tujuan dari Inaportnet untuk mempercepat proses izin surat persetujuan berlayar untuk menciptakan pelayanan kapal yang berkualitas dan efisien. Penelitian ini bertujuan untuk mengetahui peran Inaportnet dalam penerbitan surat persetujuan berlayar serta untuk mengetahui kendala-kendala yang dihadapi dan upaya yang dilakukan dalam penerbitan surat persetujuan berlayar melalui Inaportnet di Kantor Kersyahbandaran dan Otoritas Pelabuhan Kelas I Pontianak. Metode penelitian ini menggunakan metode kualitatif deskriptif dengan melakukan wawancara kepada responden, observasi, dan dokumentasi. Hasil penelitian yang dilakukan oleh peneliti bahwasanya didapatkan rata-rata naik turunnya laju pertumbuhan dari tahun 2019-2023 sebesar 7%. Hasil tersebut mengalami peningkatan dari tahun-tahun sebelumnya. Hal ini membuktikan bahwa peran Inaportnet untuk menunjang kelancaran penerbitan surat persetujuan berlayar sudah berjalan baik. Namun kendala terbesar dalam penerapan Inaportnet adalah masih perlunya peningkatan kualitas koneksi internet, supaya pengguna jasa lebih mudah dalam mengoperasikan sistem Inaportnet.
