Design of Solar-Powered Automatic Plant Watering Based on Internet of Things Agus Supardi, Afnan Hajidah Fara Anisa Department of Electrical Engineering, Universitas Muhammadiyah Surakarta, Surakarta, Central Java, Indonesia Abstract Water is crucial to the growth of plants. Without enough water to meet their demands, plants cannot develop healthily. Therefore, watering the plants must be done regularly. The majority of farmers still hand-water their plants- thus, they require automated plant-watering equipment. This study aims to design a solar-powered automatic plant watering based on the Internet of Things. This equipment utilizes soil moisture sensors to water plants automatically. The soil moisture data read by the NodeMCU ESP8266 microcontroller will be used as a reference for automatically turning on and off the water pump. Solar panels are utilized to bridge the gap in sources of electricity on agricultural property. The INA21 sensor is used to read solar panel output data, such as voltage and current. All of the sensor^s data will be sent to Blynk via the WiFi module and shown on the LCD for monitoring purposes. Comparing soil tester and soil moisture sensor results yields an error of 3.1%. The equipment was tested in the morning by manually running the water pump for five minutes, or until the soil moisture reached 78%. When the soil humidity drops to 37% in the afternoon, the water pump turns on automatically. Plant watering stops automatically after 4 minutes and 13 seconds when the soil moisture has reached 71%. The solar panel supplies the water pump with a voltage of 12.08 V and a current of 1.08 A.

The Influence of the Concentration of Palm-Based MES Surfactant with 96% Ethanol Additive on Aqueous Ability and Phase Behavior in 39-degree API Crude Oil Muhammad Faiz1, Rini Setiati2*, Havidh Pramadika1, Muhammad Taufiq Fathaddin2, Berkah Hani3 1Departement of Petroleum Engineering, Universitas Trisakti, Jakarta, Indonesia 2Master Program of Petroleum Engineering, Universitas Trisakti, Jakarta, Indonesia 3Department of Petroleum Engineering, Universitas Tanri Abeng, Jakarta, Indonesia Corresponding Emails: rinisetiati[at]trisakti.ac.id Abstract This study examines Enhanced Oil Recovery (EOR) via surfactant flooding, specifically using plant-derived Methyl Ester Sulfonate (MES) surfactant from palm oil. It assesses MES surfactant^s impact on aqueous ability and phase behavior in a 39-degree API crude oil reservoir. In this study, varied surfactant concentrations, supplemented with 96% ethanol as a co-surfactant (ranging from 0.5% to 2%), underwent stability tests. These involved heating the solutions in test tubes at 60 degree Celsius for 2 weeks. Phase behavior tests combine palm-based MES surfactant and crude oil at equal volume ratios, forming an emulsion. The emulsion^s condition was observed over 3 weeks in an oven. The research results show clear and homogeneous MES surfactant solutions. The Phase Behavior test produced a stable middle-phase microemulsion at a 25.75% volume, maintained with a 2% MES surfactant concentration and 2% co-surfactant concentration. In contrast, the previous study without co-surfactant only yielded an upper-phase emulsion. From these results, it can be concluded that the addition of co-surfactant can transform upper-phase emulsion into middle-phase emulsion. In this study, palm-based MES surfactant can be used as a surfactant injection fluid, with a composition of 2% MES surfactant and 2% co-surfactant, resulting in a middle-phase microemulsion of 25.75%.

THE URGENCY OF CUSTOMARY LAW IN PUBLIC LIFE IN INDONESIA AT THE MODERN ERA Ulya Shafa Firdausi, Ferry Irawan Febriansyah, Alfalachu Indiantoro, Hasto Prianggoro, Iqbal Nafi Nur Ikhram Universitas Muhammadiyah Ponorogo Abstract This article explains the urgency of the customary law on modern - day Indonesian life and the role that law can play in people^s lives. The purpose of this research is to celebrate the anniversary of civil law in the community of the United States of America. The research method used is the normative research method. The study suggests that the customary law is a law that reflects the personality and soul of a nation, so it is believed that some of the customary laws must be relevant to the establishment of an Indonesian legal system. Because the constitutional arrangement as it has been null and void eliminates the prevailing jurisdictional fact, the existing legal system authorizes the behavior of society in their daily lives. Indonesian social realities point to the existence of more than one legal system that effectively governs people^s lives, leading to the existence of a system of laws outside the formal law system that is enforced against the existence of indigenous peoples by their system. As part of the social reality of Indonesia, the existence of these so-called indigenous peoples obviously cannot be understated, even then a growing tendency for their existence to be maintained and fought for more in favor of the introduction of cultural rights as part of human rights. The conclusion is that the traditional laws of Indonesia are essential and necessary in people^s lives and as the basis for formal understates.

REGULATORY SANDBOX: DECRYPTING INDONESIA^S ATTEMPTS TO REGULATE FINTECH DISRUPTION Wardah Yuspin, Aditya Nurrahman, Mohd Zakhiri Md Nor Faculty of Law, Universitas Muhammadiyah Surakarta, Surakarta, Indonesia School of Law, Universiti Utara Malaysia, Kedah, Malaysia Abstract Introduction: The rapid development of Fintech and Shariah Fintech in Indonesia presents concerns because fintech development considerably outpaces the rate at which regulators issue legal standards. Then, implementing the Regulatory Sandbox is the most excellent solution to this problem. Purpose: As a result, this article aims to compare the regulatory sandbox frameworks of Indonesia and Malaysia. Method: The qualitative research method was used in this study. Data will be gathered through library research and a semi-structured interview. A comparison method is also used to analyze the data. Main Finding: The findings of this study show that the Malaysian version of the Regulatory Sandbox is more accessible to assess than the Indonesian version because the assessment is agreed upon by both parties, Fintech players and the Central Bank of Malaysia (BNM), and the Malaysian version of the Regulatory Sandbox has a more apparent status of permitted or rejected. The Malaysian Central Bank oversees the Regulatory Sandbox, making the process faster, more effective, and efficient. Implementing the Regulatory Sandbox has led to a 10% decline in registered Shariah Fintech and a 100% increase in licensed Shariah Fintech. Aside from the sandbox, the enabling components that assist Shariah Fintech in Malaysia in developing swiftly are regulatory factors, good educational institutions, and infrastructure that satisfies research needs to promote the expansion of Malaysia^s Fintech industry. Implication: A lack of study also compares the Indonesian version of the Regulatory Sandbox to the Malaysian version. However, implementing the Regulatory Sandbox in Fintech and Shariah Fintech in Indonesia needs to be improved.

Traditional Knowledge and Intellectual Property Rights Shu-Mei Tang, Yen-Tzu Chuang Financial & Economic Law, Asia University, Taiwan Abstract Caused by the information delivery mechanism of traditional knowledge being collective memory of indigenous people passed down through generations, it differs from the traditional intellectual property framework that modern society use. Essential to the development of new drugs, this indigenous knowledge on plants and animals plays a crucial role. It not only contributes to their own survival but also holds immense value for the broader benefit of humanity. Given the global demand for medicinal botanicals, preserving biodiversity becomes imperative for the well-being of future generations. However, extending intellectual property rights to indigenous knowledge presents challenges due to its inherent nature. The current era witnesses a shift in traditional medicine, with increased efforts to involve indigenous people and local communities in international negotiations and policymaking processes related to their knowledge and resources. While offering clear directions on patentability determination, there is a need for improved provisions to balance intellectual property rights and the public interest.

This is a serious problem whose root cause lies in the country^s low commitment to reducing CO2 emissions due to corrupt practices and weak democracy (Povitkina, 2018), as well as how the influence of oligarchic capitalism that aggressively invests in foreign and creates natural damage, deforestation, and degradation of environmental quality (Goerner, 2019). The extent of the role of international legal mechanisms under the 2015 Paris Convention to overcome these problems. This research question are: (1). Legal accountability for perpetrators of corruption in the energy sector that contribute to the adverse effects of climate change within the framework of international law- (2). Diplomatic mechanisms and international law as well as national legal mechanisms in preventing corruption in the energy sector in an effort to prevent climate change. This research uses socio-legal methods, to identify political-economic aspects that influence the State policies and the commitment of the international community regarding eradication corruption in energy and climate change. The results of this study explain that limited jurisdiction to deal with perpetrators of energy corruption crimes makes compliance in the prevention of corruption crimes highly dependent on the political-legal of each country, including for TNCs / MNCs that invest abroad and bribe foreign public officials in accordance with UNCAC regulations. Therefore, the importance of international cooperation in tackling climate change as a follow-up to the 2015 Paris convention, both universal, regional, and bilateral cooperation, including encouraging TNC / MNC compliance in making green investments in anticipating climate change that occurs as a direct or indirect result of corruption in the energy sectorit This Sample Abstract You Can Edit It Again Later Keywords: Energy Sector Corruption, Climate Change, International Cooperation Share Link | Plain Format | Corresponding Author (Satria Unggul Wicaksana Prakasa)

Effect of Partial Substitution of Broiler Chicken Rations with Gliricidia Sepium Leaf Meal on Production Performance, Carcass, Fat and Digestive Organs Ali Mursyid Wahyu Mulyono (a), Muhammad Husein (a*), Gilang Prasetyo (a), Wiwit Solichah (a), Sri Sukaryani (a), Diwi Acita Irawati (b) a) Faculty of Agriculture, Universitas Veteran Bangun Nusantara, Indonesia *muhhusein0102[at]gmail.com b) Vocational Faculty , Universitas Muhammadiyah Karanganyar, Indonesia Abstract The research aims to determine the effect of the substitution of Gliricidia sepium leaf meal (GLM) in broiler rations on production performance, carcass weight, fat and digestive organs. The experimental method used a Completely Randomized Design (CRD) with five treatments and four replications using 100 broiler chickens aged 11 days. The treatments in this study consisted of P0: 100% commercial ration, P1: 98% commercial ration + 2% GLM, P2: 96% commercial ration + 4% GLM, P3: 94% commercial ration + 6% GLM, and P4: 92% commercial ration + 8% GLM. The ration treatment is given to chickens aged 11 days until harvest 32 days. The parameters observed included production performance such as feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR), carcass, fat and digestive organs such as proventriculus weight, gizzard weight, duodenum weight, and jejunum + ileum weight. Rations and drinking water are provided ad libitum. The research results showed that the use of GLM to substitute feed up to a level of 8% did not have a significant effect (p>0.05) on production performance, fat and digestive organs. However, carcass weight yielded significant results (p<0.05). This research concluded that the substitution of part of the broiler chicken ration with Gliricidia sepium leaf meal up to a level of 8% in the chicken ration did not have a significant effect on the production performance, fat and digestive organs of broiler chickens, but has a significant impact on feed conversion ratio and percentage of carcass weight. The best use of Gliricidia sepium leaf meal in broiler rations is at the 4% level.

Until now, no information has been reported regarding further phytochemical tests and antibacterial activity of ecoenzyme solution. Based on these facts, it was deemed necessary to carry out this research in order to obtain scientific information regarding phytochemical activity using thin layer chromatography (TLC) as well as antibacterial activity contained in ecoenzyme solution. Initial screening for phytochemical content was carried out by testing alkaloids compound using the Wagner method, testing flavonoids and saponins compound using strong acid method. Further phytochemical tests were carried out using TLC using a silica gel plate with mobile phase, i.e. Methanol: ammonia for alkaloid test, n-hexane: ethyl acetate: formic acid for flavonoid test, and chloroform: methanol for saponin test. Antibacterial activity test was carried out using disc method. Initial screening results on the phytochemical content of ecoenzyme solutions showed that three ecoenzyme solutions tested did not contain saponins. The TLC results showed that ecoenzyme solution derived from skin of 3 types of fruit contained flavonoids and saponins, also this ecoenzyme has the best antibacterial activity against gram-positive and negative bacteria.
