    Abstract

    This study explores how to improve the productivity of hydroponic leafy vegetables by balancing Total Dissolved Solids (TDS) and nutrient solution pH. Using bok choy in a floating raft system, the research applies a controlled experimental design to observe how these parameters interact in supporting vegetative growth and yield. Daily monitoring and careful adjustment of nutrient levels and pH are emphasized to ensure optimal nutrient uptake. Balanced TDS and pH conditions enhanced leaf formation and biomass accumulation, while imbalances caused nutrient stress and growth inhibition. This study offers practical guidance for growers to synchronize TDS and pH in real-time for improved nutrient management. The findings contribute to precision hydroponics aligned with sustainable agriculture, specifically supporting sustainable development goals (SDGs) for SDG 2 (Zero Hunger) through efficient food production and SDG 12 (Responsible Consumption and Production) by encouraging optimal use of agricultural inputs. © 2026 Universitas Pendidikan Indonesia.

    Authors: Mira Suryani, Setiawan Hadi, Ayi Muhammad Iqbal Nasuha

    DOI: 10.1109/IAC.2016.7905698

    Abstract

    Nowadays, the development of information technology both in terms of hardware and software has been growing rapidly. Many people used technology to search many types of information. On the other hand, there are information on Sundanese ancient manuscript as cultural heritage with many valuable information still accessed manually, such as the manuscript which located in Situs Kabuyutan Ciburuy, Garut, Jawa Barat. Many people with many purposes (i.e. Research, education, etc.) came to access directly. Its becoming a problem because due to lack of maintainability, the manuscripts became fragile. Furthermore, the information will be lost. So, the emergency solution should be proposed to preserve this valuable heritage. We proposed a retrieval system using the probability approach that can be effective for search the information in ancient Sundanese language. The two probability approaches: Bayesian Networks and Divergence form Randomness have been compared. The 50 queries for three different types of structured query have been run and evaluated by Mean Average Precision (MAP). The results give that the effective methods come from Bayesian Network. There is another finding during the building process of retrieval system. The interactive visualization can be delivered by the retrieval system according to the given query. © 2016 IEEE.

  • Adventure Game as Learning Media for Introducing Music Interval and Ear Training to Kids

    Adventure Game as Learning Media for Introducing Music Interval and Ear Training to Kids

    Authors: Muhammad Ilham Rizqyawan, Galih Hermawan

    DOI: 10.1109/ICACOMIT.2015.7440200

    Abstract

    Interval plays is a major role in music theory so that almost every musician must recognize musical intervals. On the other hand, interval can not be separated from relative pitch, an ability to recognize interval by ear. A common problem in learning music theory and ear training are it can be bored, less fun and less challenging for students. Therefore, Game-Based Learning (GBL) is proposed in this study as a learning method for musical interval and ear training. An experiment with pretest and post-test is conducted, and as a treatment, an adventure game with proposed approach was built. Pre-test and post-test includes both theoretical and relative pitch test. Theoretical test is written test with multiple choices of theoretical questions about learning material presented on each stage. Relative pitch test were conducted by playing a random musical interval and asked the student to guess what interval it is. The result is the game could give an improvement in theoretical test score by 79.22% and 19.23% in relative pitch test. © 2015 IEEE.

  • Predictors of Life Aspirations’ Fulfillment as an effort of Social Workers to Improve the Living Standards of Rural Community

    Authors: Dewi Kurniasih ; Yudi Rusfiana

    DOI: –

    Abstract

    With prevalent poverty, poor health conditions, limited economic possibilities, and limited access to education, rural people are deprived of most of life’s fundamental essentials. Several social organizations have recognized these potential problems and are attempting to improve rural communities. Considering the importance of social organizations in enhancing the living standards of rural communities, the current study investigates the role of social workers, i.e., rural familiarity and interest, social connections, and place integration, in enhancing community participation and satisfaction, thereby enabling individuals to realize their life goals. A quantitative research approach was utilized to collect data from 480 socially low-income families in rural communities in the Indonesian provinces of South Kalimantan and Banjarmasin. By statistically evaluating the obtained data, it was shown that social workers’ traits were vital in providing rural communities with employment prospects by beginning various programs to encourage their involvement and contentment with such projects and activities. Their higher degree of happiness and participation led to realizing their life goals. This study contributes to the existing sociology literature by giving empirical evidence about the role of social workers in enhancing the fulfillment of life aspirations in rural communities, resulting in higher living standards. © 2022, Oxbridge Publishing House.
