Abstract

The oxygen demand in Salatiga city is increasing due to the increasing of population and vehicles. This oxygen can be met if the development of Green Open Space (GOS) is growing, However, this has not been well identified how many GOS are needed for oxygen demands in the city of Salatiga. The purpose of this research is to identify how many green open spaces are needed in Salatiga city based on the oxygen demand there. This research uses a quantitative descriptive method by calculating the area of land use included in the category of GOS, and calculating the oxygen demand of citizens and motorized vehicles. In determining the need for green space, calculations are carried out using the Gerarkis formula to obtain the results of green space needs by calculating the green space based on oxygen demand. Based on the analysis of land use, the total GOS in 2023 for the city of Salatiga was 1,046.21 hectares which consists of green belt, horticultural areas, plantation areas, local protection areas, cemeteries, urban forests and parks. The trend of oxygen demand increases in line with the population growth from 2018 to 2022; along with increasing motorized vehicles, while buses have decreased due people are not willing to use public transport. It can be concluded that the existing green spaces in Salatiga City cannot meet the oxygen demand of the population and motorized vehicles. Where the green space area must be increased to meet oxygen demand based on population and motor vehicle data in 2023 is 267.21 hectares

Abstract

Onion (Allium fistulosum L.) is one of the plants that is used as a spice in cooking. Leaf onions can be planted on peat soil, but to get good growth, proper fertilization is needed because of the low nutrient content in peat soil. The purpose of this study is to obtain the best dose of NPK fertilizer enriched with biofertilizer for the growth and yield of leeks on peat soils. This research was carried out in the experimental land of the Faculty of Agriculture, Tanjungpura University from February 2024 to May 2024. The method used was a Complete Random Design (RAL) which consisted of 5 levels of treatment that were repeated 4 times, each replicate consisted of 4 plant samples so that there were a total of 80 plants. The treatment levels used in this study are as follows: h1 = NPK 400kg/ha, h2 = NPK 350 kg/ha, h3 = NPK 300 kg/ha, h4 = NPK 250 kg/ha, h5 = NPK 200 kg/ha. The variables observed in this study were plant height, number of saplings per clump, fresh weight of plants, root volume, and dry weight of plants. The results showed that the application of NPK fertilizer enriched with biofertilizer at a dose of 200 kg/ha was the best dose and could streamline the use of NPK fertilizer by 50% of the NPK fertilizer dose of 400 kg/ha in increasing the growth and yield of onion on peat soil.

Abstract

The use of agricultural technology supported by competency and extension is expected to increase the motivation of cocoa farmers in the Jayapura district and have an impact on improving the welfare of farmers. In this research, we will examine how competence, agricultural technology, and extension impact performance, which is mediated by motivation. Questionnaires were distributed to 210 cocoa farmers in Jayapura district, and the data collected was analyzed using covariance-based SEM (CB-SEM). The results show that competence, agricultural technology, and extension significantly affect motivation and performance. Likewise, motivation has a significant effect on farmer performance and is significant in mediating the influence of competence, agricultural technology, and extension on performance. Based on these findings, it is hoped that the Jayapura Regency Agriculture Service will be able to provide education to farmers in using agricultural technology so that the competence and motivation of cocoa farmers in the Jayapura Regency will increase.

Abstract

This study aims to 1) determine the description of pineapple farming 2) analyze the effect of people's business credit (KUR) on pineapple farming production in Sungai Gelam District, Muaro Jambi Regency. The data used in this study are primary data and secondary data. The analysis method used is the classical assumption test based on ordinary least square and path analysis. The percentage ratio of the amount of KUR to the total cost per hectare of pineapple farming is 210.3%, this indicates that the use of the amount of KUR loans by farmers exceeds the total cost of pineapple farming in one harvest season. The amount of KUR is too large for the total cost of farming of IDR 6,644,737 per hectare. The results of the study indicate that the variables that are significant in the use of production are the variables of land area and People's Business Credit (KUR).

Abstract

Cultivation of soybean plants in Ultisols is faced with problems of acidity and high Al content, as well as low fertility in both macro and micronutrients. This research aims to determine the effect of the interaction of chicken manure and egg shells on the availability of N, P, and K nutrients and the growth of soybean plants. The research was conducted from January to May 2022 at the Experimental Garden, Faculty of Agriculture, Tanjungpura University. A Randomized Block Design (RAK) with two factors, namely chicken manure (0, 50, 75, and 100 tons/ha) and egg shells (0, 1, 2, and 3 tons/ha) was used in this experiment. The research results showed that the interaction of providing chicken manure (100 tons/ha) and egg shells (3 tons/ha) could increase N nutrient availability by 86.66%. Providing 50 tons/ha of chicken manure can increase soil pH and P and K nutrient availability by 4.01%, 286.66%, and 95.29% respectively. The growth parameters of plant height, stem diameter, and number of leaves increased by 91.48%, 120.83%, and 221.27%, respectively. Providing 1 ton/ha of eggshells can increase soil pH by 2.48%. These results confirm that the application of chicken manure and egg shells can increase the availability of soil nutrients and increase the growth of soybean plants in Ultisols.

Abstract

 The problems in melon cultivation include the decreasing availability of agricultural land and suboptimal productivity. To address these issues, a review of melon cultivation techniques is necessary, focusing on adjusting plant spacing and increasing the number of fruits per plant. This study aims to examine the effects of plant spacing and the number of fruits per plant on melon (Cucumis melo L.) production. The research was conducted on the horticultural land of Politeknik Negeri Lampung from June to September 2022. The experimental design used was a factorial Randomized Block Design (RBD) with two factors, each repeated three times. The first factor was plant spacing with three levels: 40 cm x 60 cm (J1), 60 cm x 60 cm (J2), and 80 cm x 60 cm (J3). The second factor was the number of fruits per plant with three levels: one fruit per plant (P1), two fruits per plant (P2), and three fruits per plant (P3). The observed parameters included weight per fruit (kg), fruit weight per plant (kg), fruit diameter (cm), flesh thickness (cm), and soluble solid content (ᵒbrix). Data analysis was performed using variance analysis followed by the LSD test at 5%. The results showed that a plant spacing of 60 cm x 60 cm with two fruits per plant and a plant spacing of 80 cm x 60 cm with two fruits per plant yielded better results for all parameters except for soluble solid content.

Abstract

Hygiene products commonly contain SLS (Sodium Lauryl Sulfate) which can trigger skin irritation or cause dandruff on the scalp. Through innovation and technological advancements, a 3-in-1 soap is planned to be studied to create a natural soap that is effective and contains natural ingredients that are beneficial for skin health. The aim of this research is to determine the physical and chemical characteristics of the 3-in-1 hygiene product based on sapindus (Sapindus rarak) and pineapple peel extract, and also to assess the potential microbial contamination in the 3-in-1 hygiene product. The research method used is the RAL (Randomized Complete Block Design) with 2 factors: sapindus concentration (A=15%, 22.5%, and 30%) and pineapple peel extract (B=9%, 18%, and 27%) with 3 replications. Testing parameters include physicochemical quality (viscosity, specific gravity, foam stability, and pH) as well as the inhibition ability against S. aureus and E. coli. The results show that variations in treatment have a significant effect on all test parameters except specific gravity. The best treatment was obtained by comparing data with SNI 4085:2017, resulting in treatment A2B2 with viscosity of 10,57±0,05de cp, specific gravity of 25.99±0.09 g/ml, foam stability of 71,27±0,25e %, and pH of 4,01±0,10c, with inhibition zone against E. coli of 5±0,00a mm and 6±1,41ab mm.
