Abstract

One of the obstacles to melon cultivation is the availability of seeds and the high price of melon seeds. This condition causes the need to assemble superior melon varieties with the expected characters. This study aims to form a pure line of melon with certain superior characteristics and can be proposed as a new high-yielding variety in the open-pollinated category. The research was conducted at the Experimental Garden of the Agrotechnology Study Program, Faculty of Agriculture, Trunojoyo University, Madura, from September-December 2022. This study used a randomized block design method. The treatments used were nine pure lines of melon (PK-669, D-162, PK-361, PK-165, PK-114, D-029, D-5089, PK-211, and comparison). Each treatment was repeated three times, and each experimental unit consisted of 12 plants. Research data were analyzed using analysis of variance (ANOVA) and HSD test α = 0.05. The selection advancement was analyzed by comparing character data for each generation. The research showed that the results of the characterization of ten melon lines S0-S4 generation on the characters of fruit length, fruit diameter, flesh thickness, and melon fruit weight showed a decreasing trend in each generation. The S4 generation (9.17 °brix) in the character of the average sugar content there was an increase that was not significantly different from the S3 generation (9.03 °brix), while the number of seeds in each generation had an average value that was not significantly different but occurred an increase in the number of seeds in the S3 (372) and S4 (381) generations. An increase in one generation of the population in the linear regression equation is estimated to reduce the character of fruit length by 0.50 cm, fruit diameter by 0.465 cm, flesh thickness by 0.140 cm, fruit weight by 0.199 Kg, sugar content by 0.752 °brix, and a number of seeds by 5.4.

Abstract

Along with the development of naval technology, the roles, tasks and functions of the support of the Motorized Transport Battalion (Yon Angmor) have the complexity and dynamics of movement in supporting the implementation of Amphibious Operations, which are very important and have high traffic. In this study, conducted to identify and analyze organizational readiness, readiness in the field of Operations as an element of Satbanmin, and the readiness in the field of Logistics as an element of Satbanmin in the implementation of Amphibious Operations. The results of the measurement using SEM AMOS 23 software from the measurement model of the three variables of operational readiness, organizational readiness and logistical support readiness that affect administrative assistance support, that the operational readiness variable produces the highest value of 0.566. This means that the implementation of the operational readiness of the Yon Angmor in supporting administrative assistance in Amphibious operations can be carried out optimally and according to SOPs, despite having obstacles and problems in organizational readiness. So, to answer the existing problems, the Yon Angmor needs to plan the formation of an organization through organizational validation, as well as calculating risk management in supporting administrative assistance in the implementation of comprehensive amphibious.

Abstract

This research was conducted at the DPR RI Building Office in September 2022 with the aim of examining the extent to which management influences the Biotic, Abiotic and Cultural Environment in realizing the DPR RI as a Modern Parliament with a sample of 30 people from DPR RI Office Employees. This study uses a descriptive quantitative method, namely research that describes the research object at the current state based on the facts as they are, then analyzed and interpreted using IBM SPSS Version 27 Software. The research results of the biotic environment variable (X1) have a positive and significant effect on the manifestation of the DPR RI as a modern parliament complex (Y) with an R value of 0.877, while the coefficient of determination (R2) is 0.769 or 76.9%. This shows that the biotic environment variable (X1) has a contribution of 76.9% to the realization of the DPR RI as a modern parliament (Y) variable. The abiotic environment variable (X2) has a positive and significant effect on the Realization of the DPR RI as a modern parliament (Y), the R value is 0.786. While the coefficient of determination (R2) is 0.617 or 61.7%. This shows that the Abiotic Environment variable (X2) has a contribution of 61.7% to the Realization of the DPR RI as a Modern Parliament (Y) variable. Biotic environment (X1), abiotic environment (X2) and cultural (X3) variables have a positive and significant effect on the realization of the DPR RI as a modern parliament (Y). The R value is 0.945, while the coefficient of determination (R2) is 0.893 or 89.3%.
