Abstract

The productivity of plant cultivation can be increased through intensive care and maintenance. Maintenance and maintenance consist of applying fertilizers or nutrients, weeding, pruning, and watering. Watering systems in hydroponic, aquaponic, and other plant cultivation will affect crop yields. Watering is important in maintaining lost moisture during the day, and at night as a substitute for the moisture lost at night. This study aims to design a watering tool for plant cultivation using the help of digital Internet of Things (IoT) technology. To make plant cultivation there is no lack and excess of water and nutrients. This tool can do watering remotely and can monitor moisture and soil temperature conditions via a smartphone device. Apart from helping farmers, this tool can be installed in plantations, nurseries, city parks, hotels, offices, and homes.

Abstract

The economy of a country is basically supported by many sectors, one of which is the automotive industry sector with the designation as a provider of transportation facilities. The policy regarding transportation facilities is supported by the ministry of industry which issued a policy on environmentally friendly cars or low cost green cars (LCGC). Apart from being environmentally friendly, the car also has an affordable price in the community. Forecasting sales of LCGC cars is important for many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to company targets. This will have an impact on the life and death of the automotive industry sector in the region. Important forecasting is done by many companies that use past sales data to predict the amount of production that must be done so that goods continue to sell according to the company's target. The data used in this research is secondary data. The secondary data needed in this study is the data on LCGC car sales in Indonesia from December 2019 to November 2020 obtained from secondary data sources. The data analysis method used in this research is exponential smoothing and trend analysis using POM QM software for Windows. The results also show that a good method to use as a sales forecasting method is the exponential smoothing method. This is because this method has a smaller MAPE value than the MAPE value in the trend analysis method. The MAPE figure for exponential smoothing is 4.9%, while the MAPE figure on the trend analysis method is 6.69%. In the exponential smoothing method, it is predicted that the sales of LCGC type cars in the next period are approximately 8448 units, while according to the trend analysis method, the sales forecast for the next period is 3894 units.

Abstract

This study aims to analyze the planning of sugar production capacity is efficient or not in PG Mojo Sragen. Although the level of sugar production capacity in a particular year still exceeds capacity and also lacks capacity. The production capacity planning analyzed includes the available capacity and the required capacity of each station, namely the refining station, evaporation, cooking, turning, Waste Water Treatment Plant (WWTP), and stamfloor (sugar packaging place). The analysis method used is RCCP (Rought Cut Capacity Planning). The results showed that the comparison of the efficiency of each workstation which was said to be inefficient was found at the evaporation workstation, WWTP, and stamfloor. The three stations have lower available capacity compared to the higher required capacity. This research is expected to provide insight for PG Mojo Sragen to increase available capacity through better alternatives.

Abstract

In Oyster Mushroom cultivation, nutrition is one of the factors that affect productivity. Eggshells are known to contain substances that can be used as nutrients in Oyster Mushrooms because they contain 98.2% calcium carbonate. Other nutritional content is 0.9% magnesium and 0.9% phosphorus, the eggshell membrane consists of 69% protein, 2.5% fat, 1.5% water and 27% ash which are substances needed by mushrooms to live. An experiment to study the effect of three dosage levels of eggshell nutrients on the growth of white oyster mushrooms (Pleurotus ostreatus). The experiment was designed in a completely randomised design with 10 treatments and four replications. The treatments were: Control (without eggshell nutrition), P1 25 grams, P2 50 grams, P3 75 grams. Thus, there were 40 experimental sample units. This experiment was conducted from 1 July to 30 July 2024. The experiment was conducted at CV. Lembah Spora, Polokarto Village, Polokarto District, Sukoharjo Regency.

Abstract

The purpose of this study is to examine the degree of GDP inequality between Central Java Province's districts and cities. This study's methodology is the Theil Index, which uses secondary data from GDP based on relevant prices for the business sector in 2024 that were obtained from the Central Statistics Agency (BPS). According to the study's findings, the degree of inequality in Central Java Province is indicated by the Theil Index, which has a value of 0.837, or nearly 1. This value shows that there is an uneven distribution of GDP between regions, with Semarang City having the highest GDP at 208,797 and Magelang City having the lowest at 7,690. Although there are still disparities or inequality between districts or cities due to variations in the GDP distribution process between Central Java regions, this indicates that the amount of disparity in the region is comparatively low. The processing industry sector is the largest contributor to Central Java's GDP, while other services are the least significant contributor.

Abstract

The diversification of the Kampung Lele business through catfish chips products aims to increase the income of farmers and absorb the relatively large fresh catfish sizes, namely 1 kg containing 3, 4, 5 that are not sold. In reality, catfish chips products face obstacles in marketing because there is no team that connects the sale of catfish chips products outside Java and people do not buy catfish chips every day, so it has not been able to increase the income of catfish farmers in Kampung Lele Boyolali. The purpose of this study is to determine the market potential of catfish chips in Kampung Lele Boyolali. The analytical methods used were Return on Investment (ROI) and marketing margin analysis. The ROI analysis showed an efficiency of 79%, and a marketing margin of Rp 12,000 per three catfish chip variants. Therefore, catfish chip production in Kampung Lele Boyolali has the potential to be further developed with a market development strategy that accommodates and is appropriate for the future.
