Abstract

Drug development continues to be carried out so that drugs can work effectively. Creating a drug formula can be achieved by combining two or more synergistic drug compounds by hybridization, blending, or synthesis. This study reports findings of antioxidant activity using the good DPPH method from the synthesis of eugenol and salicylic acid using the encapsulation technique. The encapsulation technique uses chitosan as a coating material to protect the active ingredients, taking advantage of its unique functional characteristics, including the ability to form bonds with the crosslink agent sodium tripolyphosphate (Na-TPP) at a speed of 13,500 rpm with a pH of 4.2 to optimize the formulation. The encapsulation system produced majority particles measuring 241.0 ± 19.8 nm, with an encapsulation efficiency of 58.29 ± 0.40%. The results of the compound antioxidant test (CS-ES NP) showed better results than pure ES, with an IC50 value of 1.64 ?g/mL. The morphology results after encapsulation showed round and dense particles, indicating that the ES compound was successfully encapsulated. Keywords: encapsulation, antioxidant, eugenyl salicylate, blending

Abstract

Penelitian ini menganalisis bagaimana luas lahan, modal, dan hasil produksi mempengaruhi pendapatan petani adalah tujuan dari budidaya kentang, dalam konteks Desa Kanreapia di Kabupaten Gowa. Tujuannya adalah untuk mengungkap dinamika spesifik yang mempengaruhi pendapatan petani kentang di Kabupaten Gowa dalam rangka menunjang ketahanan pangan nasional. Keunikan penelitian ini terletak pada dinamika di Desa Kanreapia, yang dapat memberikan kontribusi pengetahuan dan keilmuan yang berbeda dari pengetahuan yang sudah ada saat ini. Penelitian ini menggunakan analisis regresi untuk menilai signifikansi statistik dari luas lahan, modal, dan produksivitas pertanian terhadap pendapatan petani. Hasil penelitian menunjukkan bahwa luas lahan dan modal tidak mempengaruhi, sementara hasil produksi dan pendapatan menunjukan nilai positif signifikan. Implikasi praktis dari penelitian ini adalah dapat menjadi rekomondasi bagi para pembuat kebijakan dan praktisi yang terlibat dalam pembangunan pertanian berkelanjutan, dan memberikan strategi untuk meningkatkan kesejahteraan finansial petani kentang di Indonesia. Kata kunci: luas lahan, modal, hasil produksi, pendapatan, petani kentang

Abstract

Limpasan yang sering terjadi di Kampung Andamui Masjid, Kecamatan Curug, Kota Serang, terutama saat musim hujan, disebabkan oleh sistem drainase yang tidak optimal. Penelitian ini bertujuan untuk menganalisis kondisi drainase yang ada dan mencari solusi terbaik untuk mengatasi permasalahan banjir tersebut. Metode penelitian meliputi observasi lapangan, wawancara, dan analisis data curah hujan selama 15 tahun terakhir menggunakan metode Log Pearson Tipe III dan Gumbel. Hasil penelitian menunjukkan bahwa drainase di wilayah ini sering tersumbat oleh limbah rumah tangga dan dimensinya yang belum memadai sehingga tidak mampu menampung aliran air dengan baik. Seperti pada Area II, hasil perhitungan debit rancangan adalah 0,0074 m³/detik, sementara debit saluran drainase sebesar 0,178 m³/detik. Ketidaksesuaian antara debit rancangan dan dimensi saluran drainase ini menyebabkan terjadinya limpasan air yang berkontribusi pada banjir. Untuk mengatasi masalah ini, maka diperlukan evaluasi kondisi drainase serta merekomendasikan penerapan konsep green infrastructure yang memanfaatkan vegetasi alami untuk meningkatkan penyerapan air dan mengurangi limpasan permukaan. Partisipasi aktif dari masyarakat dan dukungan pemerintah sangat diperlukan untuk implementasi dan pemeliharaan jangka panjang dari solusi ini.Keywords: kampung andamui masjid, drainage, runoff, green roof

Abstract

Glass waste is one of the residual waste construction materials that can be recycled by turning its particles into smaller sizes so that the processing of glass waste will be easier, especially in terms of safety. This study aims to test the performance and performance of glass waste crushing machines, determine the rotation speed of the shredder gear in glass waste crushing machines and to determine the production efficiency of glass waste crushing machines. This research uses experimental methods with field experiments, by analyzing the machine directly. The parameters observed were testing the feasibility of tool performance by looking at the results of glass waste shredding, the production efficiency of the glass waste shredder and knowing the rotation speed of the crushing gear in the glass waste shredder. The results showed that glass waste with a thickness of 0.2 cm that had been crushed obtained an average value of 1405.2 grams and for a thickness of 0.5 cm, 1376.2 grams. At the speed of rotation of the glass waste crusher gear, the average value obtained by glass with a thickness of 0.2 cm is more than glass with a thickness of 0.5 cm, namely 16.98 rpm while glass with a thickness of 0.5 cm is 13.82 cm. The results of the calculation of the production efficiency of the glass waste shredder with a thickness of 0.2 cm have the highest result at the 5th repetition of glass entry, that is 94.80% and the lowest at the 1st repetition is 92.53%, and for glass with a thickness of 0.5 cm the highest result is obtained at the 2nd repetition of glass entry, that is 92.66% and the lowest result at the 1st repetition is 89.66%. Keywords: glass shredder machine, glass waste, waste processing, performance test, waste materials

Abstract

Indonesia is a country with the largest palm oil industry in the world. Palm oil mill effluent is oily and non-toxic liquid waste, the result of palm oil processing. Although non-toxic, the effluent can cause environmental disasters because it is dumped in open ponds and releases large amounts of methane gas and other harmful gases that cause greenhouse gas emissions. This research was conducted with experimental research methods. The purpose of this study, namely to obtain an explanation of the problem studied in the explanation in the form of a causal relationship between the dependent variable and the independent variable that affects the occurrence of the problem. In the biogas turbine section, it is made by adjusting the working principle of water turbines in general. The biogas storage section uses an existing biogas system and then the gas is channeled through a inch pipe. After that the gas flows so that it rotates the turbine and the turbine rotates then produces electricity and is accommodated in a 12 Volt battery so that it can be used at night without having to turn on the turbine. stored on the battery when the battery is full will be turned off by the control system in the device design so that it is effective and efficient.
