Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

The purpose of monitoring the water quality of Deli River at the Pemandian Alam in Mbelin Village, Sibolangit District was an effort to ensure that the Deli River at the meeting point of the Lau Betimus and Lau Petani were a Natural Bath that is safe from pollution. At the confluence point of the Lau Betimus and Lau Petani, it was observed based on the pollution index described by each station from upstream to downstream. The Deli River Pollution Index at the monitoring point of the Lau Betimus and the confluence of the Lau Petani were 0.49 and 0.55, which means the water quality is in good condition index or meets the quality standard. This means that the water quality at the observation station is still natural and has not been polluted by pollutants or waste.

Abstract

In every transaction activity in the company always affects the cash balance. Because the nature of cash is very easy to embezzle and misappropriate. So it is important to have an adequate accounting system so that the realization and use of cash can really be used to cover the company's costs. The accounting system is a cash disbursement accounting system. The purpose of this study is to determine the cash disbursement accounting system in terms of the parts involved, the documents required, the accounting records used, the procedures required, and the internal control system implemented by the company. The research methodology used is a field study by means of observation, interviews and literature studies. The steps used are to discuss the implementation of the Cash Disbursement System and Procedures at PT Federal Izumi Manufacturing. The results of the study show that the cash disbursement accounting system at PT Federal Izumi Manufacturing is fairly good, from the appropriate parts and functions, procedures, records and internal control elements to the complete and fairly good, only for the cash disbursement evidence document, namely the payment slip, only one document is made so that if the document is lost, the company does not have a backup for the document
