Abstract

Rice is a staple food in Indonesia and globally, but its production is threatened by pests such as the brown planthopper. Conventional pest control methods, including pesticides and traditional techniques, often prove ineffective and have negative environmental impacts. Light traps have been explored as an alternative due to the brown planthopper's phototactic behavior, yet existing designs lack efficiency in capturing pests. This study presents an IoT-based solar-powered pest control system that integrates light as an attractant and an electric trap for effective pest elimination. The system features real-time monitoring of voltage, current, and light intensity using an LCD display, powered by a 35 Wp solar panel and managed through an Arduino Uno microcontroller. Experimental results show that brown planthoppers are most attracted to an LED light with an intensity of 780 lux, operating at 11.5 V and 0.97 A. The system consumes 112.52 Wh, with a full battery charge requiring approximately 6 hours and 7 minutes. These findings highlight the potential of a sustainable, energy-efficient solution for pest control in rice agriculture.

Abstract

River water pollution in Cilacap Regency is caused by industrial activities related to oil refining and river crossing traffic, which generate wastewater containing Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and heavy metals such as lead. This study aims to evaluate the performance of biomass-based activated carbon—derived from coconut fronds and laban wood sawdust—in river water purification through physicochemical characterization and adsorption kinetics approaches. The activated carbon was characterized according to the Indonesian National Standard (SNI) 06-3730-1995, and its surface area was analyzed using the Brunauer–Emmett–Teller (BET) method. Characterization results for AC-PK 1(100) showed a moisture content of 0.1085%, ash content of 3.05%, iodine adsorption capacity of 571 mg/g, and a surface area of 110.595 m²/g. The adsorption process after 15 minutes demonstrated that the activated carbon was effective in reducing water quality parameters, with the pH reaching neutral (7) and TSS decreasing to 212 mg/L, meeting Class III standards based on Government Regulation No. 82 of 2001. However, the TDS value of 4690 mg/L did not meet the quality standard. Kinetic studies indicated that the first-order reaction model best described the adsorption mechanism, with R² values approaching 1. The adsorption rate constants were 0.0041 min⁻¹ for TSS and 0.0686 min⁻¹ for TDS. These findings suggest the potential application of biomass waste as a raw material for activated carbon in environmentally friendly river water purification technologies.

Abstract

Around 143,000 people die every year in developing countries due to exposure to the heavy metal lead (Pb). This, combined with increased heavy metal pollution as a result of increasing industry. Lead can enter the bodies of living creatures through food, drink, air, or through the skin. Fossil fuels, cats, pesticides, soil, toys, car batteries and other sources produce lead. Iron (Fe), Manganese (Mn), Zinc (Zn), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Nickel (Ni), and Mercury (Hg) are pollutant elements heavy metals originating from industry. These heavy metals can be harmful to human health depending on which part of the body they are most bound to. To determine the bioconcentration factor (BCF) of the heavy metal lead (Pb) in the consumption of fish originating from fishing grounds in Tegal Katilayu Cilacap sea waters. Analysis of lead (Pb) levels in sea water and the bodies of tuna, mackerel and tuna was carried out using the Atomic Absorption Spectrophotometry (AAS) instrument at the Jendral Soedirman University Laboratory. Meanwhile, sea air pH measurements were carried out directly while still at the Tegalkatilayu Cilacap waters. The sea air pH obtained was still neutral, namely 7.43 and was still in the range (6.5 -8.0). Based on the results of heavy metal tests using Atomic Absorption Spectrophotometry (AAS) of Tegalkatilayu sea air, a concentration of 0.236 ppm was obtained, which has passed the maximum quality standard of 0.05 ppm. Meanwhile, test results for the heavy metal lead (Pb) in the body of tuna were 2,291 ppm, tuna 2,892 ppm, and mackerel 0,716 ppm. The degree of acidity (pH) in Tegalkatilayu waters is still within the range (6.5 – 8.0), namely an average pH of 7.34. The lead (Pb) content in sea water was found to be an average of 0.236 ppm, according to the Decree of the Minister of Environment of the Republic of Indonesia No. 51 of 2004 concerning sea water quality standards for port waters has exceeded the maximum limit of 0.05 ppm. Meanwhile, the lead (Pb) content in the body of tuna is 2.291 ppm, tuna is 2.892 ppm, and mackerel is 0.716 ppm. This has resulted in marine air pollution and accumulation of the heavy metal lead (Pb) in fish bodies. The bioconcentration of heavy metal factors contained in the fish's body was found to be <100, which is still in the low category. There needs to be regular monitoring regarding the maximum fish consumption limit for humans per week which has accumulated heavy metals based on body weight, age and gender. Thus, it can reduce the accumulation of the heavy metal lead (Pb) in the human body. Keywords: pH of sea water, bioconcentration of heavy metal factors.

Abstract

Ketapang leaves are an example of biomass that can be used to make briquettes. However, ketapang leaves produce a low calorific value, so they require additional ingredients to increase the calorific value, one of which is coconut shell. This research aims to evaluate how variations in raw material composition and adhesive content of tapioca flour affect the quality of briquettes on the parameters of calorific value, water content, ash content, volatile substances, fixed carbon content, and density. The method applied in this research involved mixing ketapang leaf charcoal and coconut shell charcoal, then adding adhesive in the form of tapioca flour. The study results showed that all the briquettes tested met SNI 8966-2021 standards except for the density parameter. The conclusion of this study is that the greater the composition of the briquette raw materials and the lower the adhesive content of tapioca flour, the better the quality of the briquettes. The mixed briquettes that produce the best quality are composed of 20% Ketapang leaf charcoal and 80% coconut shell charcoal. The tapioca flour adhesive that delivers the best quality briquettes is at a percentage of 5%.

Abstract

Tinta cumi merupakan limbah sampingan dari cumi-cumi yang belum termanfaatkan dengan baik. Pemanfaatan tinta cumi masih terbatas pada produk segar, yang mengakibatkannya tidak bisa disimpan dalam waktu yang lama. Sehingga diperlukan olahan lanjutan untuk memperpanjang masa simpan seperti dijadikan dalam bentuk serbuk. Tujuan penelitian ini adalah untuk mengetahui karakteristik fisikokimia tinta cumi yang telah diawetkan dalam bentuk serbuk. Metode penelitian yang digunakan pada penelitian ini adalah deskriptif eksploratif dengan melakukan pengamatan pada serbuk tinta cumi. Pengamatan dilakukan dengan melakukan analisis proksimat, analisis SEM-EDX dan analisis FT-IR. Kandungan lemak dan protein serbuk tinta cumi memiliki nilai lebih rendah dibandingkan dengan bagian tubuh lainya. Analisis SEM-EDX menunjukan bahwa serbuk tinta cumi memiliki bentuk yang tidak beraturan dengan unsur penyusun utama C, N dan O. Hasil analisis FT-IR menunjukan bahwa gugus fungsi yang terdapat di dalam serbuk tinta cumi adalah gugus fungsi fenolik (O-H) dan amina (N-H) yang berpotensi menjadi senyawa antibakteri dan juga antioksidan.Kata Kunci : ABSTRACTSquid ink is a byproduct of squid that has not been utilized properly. Despite its potential, the use of squid ink is still limited to fresh products, which means it cannot be stored for a long time. Therefore, further processing is needed to extend the shelf life, such as making it into powder form. The objective of this study is to determine the physicochemical characteristics of squid ink that has been preserved in powder form. The research method used is exploratory descriptive by observing the squid ink powder. Proximate analysis, SEM-EDX analysis, and FT-IR analysis were carried out to observe the powder. The fat and protein content of squid ink powder is lower compared to other body parts. SEM-EDX analysis shows that squid ink powder has an irregular shape with the main constituent elements of Carbon, Nitrogen, and Oxygen. The results of FT-IR analysis show that squid ink powder contains functional groups of phenolic (O-H) and amine (N-H), which have the potential to be an antibacterial compound and an antioxidant.
