Distribution is the process of moving, managing, and storing goods from suppliers to customers in the supply chain. This process includes not only the delivery of raw materials from suppliers to manufacturers, but also the distribution of finished products to the end consumer. Distribution plays an important role in a company's profitability because it affects operational costs, delivery efficiency, and perceived value by customers. Successful well-managed distribution will increase customer satisfaction and strengthen the company's competitiveness in the market. PT. XYZ is one of the LPG distributors that provides 3 kg cylinders. This company serves a variety of consumers, ranging from households, small businesses, to retailers, with a coverage of distribution areas in Serang City. The distribution process is carried out based on sales orders and needs in 14 bases, where each base has a different level of demand according to consumer needs. However, PT. XYZ faces obstacles in achieving the optimal level of service, where the average service level only reaches 97.40%. An imbalance between inventory and demand at the base often leads to an oversupply or understock, resulting in backorders on some demands. This condition has a negative impact on customer satisfaction and overall distribution effectiveness. To overcome this problem, PT. XYZ developed a distribution dashboard by applying the Distribution Requirements Planning (DRP) method. Through this approach, distribution planning becomes more systematic, base needs can be met appropriately, and stocks can be managed more effectively. This dashboard also supports delivery scheduling and more coordinated marketing activities. The results of the implementation of the DRP dashboard in 2023 show a significant increase with a service level that has successfully reached 99%, minimizing backorders, and increasing customer trust and satisfaction.

Aquaponics is a combined system of fish farming techniques and hydroponic plant cultivation. Fish manure and feed residues are very dependent on the supply of nutrients in the aquaponic system of red tilapia (Oreochromis niloticus) aquaculture. The level of production of vegetable crops in a certain area is also influenced by the total nutrient input ratio of feed to domestic fish per day. The aquaponic system utilizes optimum water supply for each commodity by utilizing a recirculation system. The type of fish used is fish that live in freshwater, a type of tilapia. Fish farming includes the maintenance of fish, which pays attention to the growth and development of fish. Hydroponics itself is a way of farming without using soil as a medium but using water which contains controlled nutrients containing the essential elements needed for plant growth.

Bitcoin and Altcoin are digital currencies (cryptocurrencies) that use blockchain technology, a technology that can monitor, supervise, record, and record every transaction that occurs in digital currency. Bitcoin is decentralized, meaning it is spread everywhere, not centralized and cannot be regulated by authorities or other institutions. In making transactions, it is very necessary to recognize digital currencies such as identity, core business, projects being developed, volume of demand and supply, and other indicators. The need to find out information about coins/crypto tokens before trading, is a very helpful thing for traders because of concerns about coins/tokens that are indicated as scam or rugpull. Coinmarketcap.com and coingecko are data provider sites related to bitcoin and altcoins around the world, which can help find and analyze related information about tokens/cryptocoins to be traded, but do not guarantee accuracy, but can minimize the occurrence of greater losses. Digital currencies provide business opportunities and loopholes to be able to generate profit from every coin/token traded, but on the other hand these assets are risky for traders and investors due to their high volatility which makes market price movements difficult to predict (unpredictable). To be able to overcome this problem it is necessary to manage finances by taking 10% for trading from the main salary earned, dividing which assets are needed for trading and which are for daily / other living needs and self-control well, when is it time to trade, rest, and when to pause. That way it can save other assets when the other asset is experiencing a decline, so it doesn't disturb the main asset.
