Abstract

Abstract               There are many beach tourist destinations in Cilacap Regency, Central Java that can be visited, one of which is Widarapayung beach. Widarapayung Beach is located in Binangun District, Cilacap Regency which is managed under the auspices of the Cilacap Regency Tourism and Culture Office whose implementation is managed by the KODIM 0703 Cilacap Cooperative. The impact of the COVID-19 pandemic and the implementation of the PSBB caused the manager to have difficulty in providing information regarding the facilities available at Widarapayung Beach to potential visitors.                During the pandemic and the implementation of the PSBB, all information publications on Widarapayung beach were limited. Not all information about Widarapayung beach is known by the surrounding community or people from outside Cilacap. One of the multimedia developments that can provide visitors with the introduction of Widarapayung beach landmarks to make it easier to find more interesting information about Widarapayung beach by developing Augmented Reality technology. The result of this research activity is to implement Augmented Reality technology for the introduction of Widarapayung beach landmarks, Cilacap Regency so that visitors can more easily find out the facilities and information in Widarapayung based on Android. Keywords: augmented reality; landmark; widarapayung beach

Abstract

Assets are resources owned by an entity. Cilacap State Polytechnic is a higher education institution that has many assets. Current asset maintenance and repair services are still carried out conventionally. Each work unit must fill out a maintenance and repair proposal form and then submit it to the Maintenance, Repair, and Maintenance Unit (UP3). The proposal will be recorded and scheduled to be followed up by the Technician. The problem that occurs is that the proposal form is often scattered and even lost so the response time is often slow. In addition, maintenance and repair schedules are often not ordered according to the time of the request. This has an impact on the abandonment of work in certain work units. The purpose of this research is to create an information system for the repair and maintenance of campus assets. In order for maintenance and repair services to be carried out according to the time of the request, the FCFS method is applied. Thus, the service process for maintaining and repairing campus assets becomes more organized, schedules (queues) are sequenced, and the response time for incident handling is faster.

Abstract

Tracer study is a method used by several Vocational High Schools (SMK) to collect alumni data and monitor alumni progress. The problem is in monitoring the alumni who do not only stay in Cilacap but outside of the city as well. Moreover, the data collection method is still simple by only using a questionnaire form filled out when they take their diplomas. This condition is less effective because many alumni are still looking for a job, therefore it is difficult to check up on them all the time. This study aims to create a tracer study application using the waterfall method. The testing phase uses the Blackbox testing method. Based on the test results, the application can make it easier for BKK administrators to collect alumni data and help monitor the alumni progress by checking the percentage of alumni status and making it easier for alumni to fill out questionnaires. The results of the overall usability test conducted on 30 respondents resulted in the predicate "Very Good" with an average of 85.51%.

Abstract

Permasalahan yang dihadapi oleh para petani holtikutura di kabupaten cilacap saat ini cukup kompleks khususnya dalam hal pemasaran produk. Permasalahan tersebut diantaranya adalah metode pemasaran yang belum maksimal karena berbagai macam keterbatasan media promosi dan pengetahuan tentang cara-cara promosi sehingga hasil pertanian hanya dipasarkan di daerah Cilacap saja, serta belum optimalnya pemanfaatan teknologi dikarenakan sarana yang terbatas dan ruang gerak yang terbatas apalagi seperti kondisi sekarang yaitu pandemi covid-19. Pemasaran online yang dilakukan oleh Petani Holtikultura Cilacap (PHC) memerlukan sebuah sarana yang lebih luas cakupannya, seperti sebuah media marketplace yang khusus menjual produk hasil pertanian dari seluruh wilayah kabupaten Cilacap. Berdasarkan kesepakatan antara tim pelaksana dan mitra, maka solusi yang menjadi prioritas utama adalah masalah strategi media pemasaran, pemanfaatan marketplace untuk pemasaran hasil pertanian di seluruh wilayah kabupaten Cilacap. Kegiatan tersebut dikemas dalam suatu bentuk pelatihan-pelatihan, diantaranya pelatihan pengelolaan marketplace yang bertujuan agar hasil pertanian dapat dipasarkan ke luar daerah Cilacap.  Target luaran yang diharapkan adalah adanya peningkatan perekonomian, serta peningkatan pengetahuan anggota PHC terkait dengan sistem pemasaran dan branding yaitu digital marketing. Selain itu diharapkan adanya peningkatan kesejahteraan dan perekonomian bagi anggota PHC karena permintaan hasil pertanian yang meningkat.

Abstract

One source of regional income for Cilacap Regency is the management of vehicle parking lots. Currently, parking area management is carried out by recording the identity of the parking location based on the street name, while the withdrawal of parking fees is carried out by towing officers who come to the parking location and then record it in a book. The current management of parking lots is still inaccurate because there are several street names that have more than one parking area which results in data redundancy. The conventional parking fee collection system causes frequent discrepancies in reports due to the potential for misuse of parking fees. The absence of tools that can be used by related agencies to control reports is the cause of the problem. The research objective is to develop an information system by applying LBS technology which functions to detect parking points precisely and QR Code Detection which functions to detect the identity of parking attendants. System development uses the ADDIE model. The results of the research are an information system for mapping parking lots and picking up parking fees based on Andorid which can help manage vehicle parking lots which includes mapping the location of parking lots and picking up vehicle parking fees.

Abstract

Hydroponic system is a technique of cultivating plants without using soil as a growing medium, but using water that is given nutrients and oxygen as a growing medium. Cultivation with hydroponic techniques must be able to pay attention and control nutrients, water content, and water ph. This research aims to create a lettuce cultivation system with intelligent hydroponic techniques using the ATmega2560 microcontroller. This system uses Arduino Mega as the control center, TDS sensor to monitor nutrition, PH sensor to monitor water acidity, and ultrasonic sensor to monitor water level. The optimal growth characteristic of lettuce is that the acidity level must be at pH 5.5-6.5 with the nutrients provided at 685-950 ppm. This system can help lettuce cultivation with hydroponic techniques by monitoring and controlling nutrients, pH, and water content in cultivated plants in real time to optimize lettuce growth.

Abstract

Junk goods are no longer piles of worthless goods for businessmen who are keen to see the economic value by taking this opportunity by becoming a pelapak company to buy and sell junk goods purchased from collectors to be sold to buyers. The problems found with Pelapak include the manual recording of sales administration which has the potential to cause recording errors. Pelapak does not know for sure the stock of junk they own and those owned by collectors because the locations of the collectors are far apart. Orders of junk goods between pelapak and collectors are still via telephone so pelapak does not know which collectors are in the process of sending goods. Problems also occur on the part of collectors including unprofessional sales transactions. Based on these problems, a used goods stock management system is needed using the Economic Order Quantity (EOQ) method. The purpose of this study is to build a used goods stock management information system that can monitor the availability of used goods owned by collectors and pelapak. System development uses the prototype method and designs with concepts. The results of the research are that the system created can help find out the stock and the amount in each collector, recap sales reports, provide accurate information, facilitate business transactions and fulfill sales targets to buyers.
