Abstract

The problem of plastic waste in the ocean is a global problem that endangers the quality of sea water and the marine ecosystem as a whole. This article discusses the relationship between how to manage plastic waste and how it affects seawater quality, such as pH, temperature, salinity, dissolved oxygen (DO), and biological oxygen demand (BOD5). Research from the literature shows that plastic waste, especially microplastics and macroplastics, can affect the chemical and physical quality of sea water. For example, a decrease in pH levels due to accumulated organic acids, local heating due to sunlight absorbed by plastic, and changes in salinity due to interaction with fresh water. In addition, the accumulation of plastic causes a reduction in dissolved oxygen (DO) and an increase in BOD5 levels, which is detrimental to marine ecosystems. Decreased water quality can endanger marine species because these species are very dependent on the chemical balance of the water. Despite much research on the impact of plastic waste on water quality, there remains a gap in understanding the long-term impacts and the need for more comprehensive plastic waste management. Further research is needed to resolve these issues and create more effective management strategies.

Abstract

Government Regulation Number 61 of 2009 concerning Ports, classifies seaports in Indonesia based on a hierarchy consisting of transport ports (PU), collecting ports (PP), feeder ports (PP), consisting of: territorial feeder ports (PR) and territorial feeder ports (PR) and territorial feeder ports (PR). local feeder ports (PL Based on the decision of the Local Feeder Port (PL). In this research using literature study, where this method is a systematic, explicit and reproducible method to identify, bring up and synthesize the works of research results. The purpose of this research is to analyze the Wind Port Development Strategy Analysis of basic facilities, functional facilities and supporting facilities and problems that exist in the Gunungsitoli City Ship Port, analyzing port development The fishing port is very important for fishermen, because it is a point of preservation of land and sea and a place for storage and distribution of goods. In developing the port there must be cooperation between fishermen and communities in the coastal environment and must also be in contact with the government so that it can build a good port in North Nias Regency and get facilities that support the performance of fishermen or coastal communities. fishermen and communities in the coastal environment and must also be in contact with the government so that it can build a good port.

Abstract

One solution to urban farming is hydroponic cultivation. Currently, the development of the world of agriculture, especially in the field of hydroponics, is increasingly rapid. When compared to conventional farming, hydroponics has advantages that conventional farming does not have. One plant that is often cultivated hydroponically is the cherry tomato plant. The growth and production of tomatoes with a good hydroponic system requires the right concentration and volume of nutrients. This research used a non-factorial randomized block design (CRD) with Nutrient concentration (N) treatment, consisting of 5 levels, namely: N1 = 800 ppm, N2 = 900 ppm, N3 = 1000 ppm, N4 = 1100 ppm and N5 = 1200 ppm. The results showed that nutrient concentration had an effect on the generative growth phase, but had no significant effect on the vegetative growth phase of cherry tomato plants. Nutrient concentration influences the morphology and physiology of cherry tomato plants. Nutrient concentration had a significant effect on the production of cherry tomato plants hydroponically with the heaviest fruit weight per plant found in the AB Mix nutrient concentration of 1000 ppm (N3) of 97.89 g.

Abstract

Perkembangan teknologi digital telah mendorong perubahan signifikan dalam perilaku konsumen, khususnya dalam proses pengambilan keputusan pembelian pada konteks belanja daring. Kondisi ini menuntut pelaku usaha untuk memahami secara komprehensif faktor-faktor yang memengaruhi keputusan pembelian agar mampu bersaing secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis dan memetakan perkembangan kajian ilmiah terkait faktor-faktor penentu keputusan pembelian dengan menitikberatkan pada kualitas produk dan harga. Penelitian ini menggunakan pendekatan kualitatif dengan metode analisis bibliometrik. Data diperoleh dari publikasi ilmiah terindeks Scopus yang dikumpulkan melalui aplikasi Publish or Perish dengan rentang tahun 2018–2026, kemudian dianalisis menggunakan perangkat lunak VOSviewer. Hasil analisis menunjukkan bahwa kualitas produk dan harga merupakan determinan utama keputusan pembelian yang berinteraksi dengan variabel lain seperti citra, persepsi keadilan harga, pengalaman, dan hubungan konsumen. Pemetaan bibliometrik juga memperlihatkan adanya pergeseran fokus penelitian dari atribut produk menuju pengalaman dan hubungan konsumen, meskipun kualitas produk dan harga tetap menjadi fondasi utama dalam keputusan pembelian. Temuan penelitian ini memberikan kontribusi teoretis dalam memperkaya kajian pemasaran serta implikasi praktis bagi pelaku usaha dalam merumuskan strategi pemasaran yang berorientasi pada konsumen dan dinamika pasar digital.
