Abstract

The increase in market demand for mustard needs to be balanced with an increase in production, one of which is by utilizing peat land which is balanced with the provision of gibberellin as a plant growth regulating hormone. This study aims to determine the best concentration of gibberellin (GA3) in increasing the growth and yield of mustard on peat soil. The research was conducted at West Kalimantan Province, Southeast Pontianak Sub-district. The research was conducted from September 12nd "“ October 12nd 2020. The method used was a Completely Randomized Design with 4 levels concentration of gibberellin, namely was p1 (10 ppm); p2 (20 ppm); p3 (30 ppm); p4 (40 ppm). Each treatment was repeated 6 times and consisted of 4 plant samples so the whole plant samples were 96 plants. The variables observed were plant height, number of leaves, leaf area, root volume, plant dry weight and plant fresh weight. The results showed the various concentrations of gibberellin could increase plant height, leaf number, leaf area and fresh weight of caisim mustard plants. The efficient gibberellin concentration was obtained at 30 ppm based on the yield potential of the plant, namely plant fresh weight with an average of 23.72 grams.

Abstract

Security comes from the Latin word secure, significantly different from the dangers, fears, and threats associated with traditional and non-traditional security methods. Meanwhile, defense is defined as the most vital technology for the state in carrying out its national security function. National security is defined as the dynamic state of a country which covers all aspects of the nation's life in facing threats. National security includes protection for the state, society, and individuals. Until now, experts have provided several different definitions of the terms security and defense. This article analyzes the current digital information security threats in national security strategies and the implementation of adequate legal protections. This article applies a descriptive qualitative research approach by conducting document analysis. This article describes various information security threats in Indonesia, including disinformation, privilege escalation, and protection against phishing threats, data forgery, and card crime. The similarities and differences between the concepts of defense and security can be observed through regulations, the terminology used, institutions, and constitutions. This article shows that national information security is closely related to policy and closely relates to security, especially ITE policies. It cannot be separated that the security situation of a country depends on security and defense but synergistically with other factors, namely economic, political, legal, socio-cultural, ideological, geographical, and demographic.

Abstract

Kalimantan relies significantly on peat water as a water source. However, due to its high organic content, acidic nature, and intense color, it is not safe to drink. To address this issue, researchers proposed an eco-friendly coagulant, calcium lactate, to remove suspended solids. To test its effectiveness, the coagulant was compared to membrane technologies, specifically nanofiltration (NF) and reverse osmosis (RO), at Rasau Jaya General Hospital in West Kalimantan between April and October 2022. Different pressures, 40, 60, and 80 Psi, were used to test both methods. Before and after treatment, the levels of total coliform, E. coli, pH, total dissolved solid (TDS), turbidity, color, and calcium were examined. The results showed that the best outcomes were achieved at 60 Psi. The combination of 0.8 mg/l calcium lactate and NF met all the standard values, except for color (29 TCU). Calcium lactate and RO, however, produced safe drinking water at 60 Psi from all analyzed parameters (E. coli=0, total coliform=0, pH=6.5, TDS=7.1, nephelometric turbidity units (NTU)=2.8 NTU, color=8.7 TCU, and calcium 7.6 mg/l). The reduction of bacteriological substances achieved 100% for both methods. Overall, the combination of calcium lactate and RO yielded slightly better results than NF.
