Abstract

Hermetia illucens, well-known as black soldier fly (BSF), is an insect easily found in subtropical and tropical regions. It contains high protein and lipids. BSF is known as one of the biological agents consuming organic components, thus having a high potential to overcome organic waste problems. BSF has promising advantages due to its long development time in the larval stage (compared to other flies) and its ability to self-separate from organic waste. BSF with large protein and lipid content can substitute the commonly used protein source in aquaculture, poultry and livestock compound diet formulation, which can be an option to overcome limited sources of future food and feed insecurity. This review analyses the latest study of bioconversion using BSF from the viewpoint of nutrient composition, degradation rate and biomass results from different feed treatments. Various feed and growth mediums have been studied to obtain high protein and lipid biomass. Hopefully, the information will provide new research directions and solutions for converting agro-industrial waste using bioconversion with BSF.

Abstract

This paper aimed to comprehensively review the potential valorization of oil palm empty fruit bunches (OPEFBs) into activated carbon and its potential application. Activated carbon is carbon processed through dual phases, including carbonization and activation. Firstly, this process converts biomass into carbon thermally with zero to little oxygen conditions. Next, the carbon needs to be activated to stimulate the formation of pores and reduce impurities. The activated carbon’s quality is influenced by the activation process, which can be done physically, chemically, or physiochemically. Activated carbon has an amorphous structure and abundant internal pore structure, thus increasing the surface area. In Indonesia, the quality of active carbon is regulated by Indonesian National Standards or SNI 06-370-1995.  The factors influencing the activation step include activator agent type,  activator agent concentration, activation ratio and time, etc. . Generally, activated carbon can be widely applied to various sectors, such as agriculture (i.e., slow-released fertilizer, fertilizer, etc.), waste treatment (i.e., adsorbent, activator in anaerobic digestion/AD, bioremediation, etc.), gas purification, ceramic membrane, etc. However, further in-depth investigation is required to determine potential scaling-up and commercialization.

Abstract

Biothermoplastic composites are mixtures of two or more polymers from biological materials with other materials that can melt when heated and harden again when cooled. The formation of packaging trays from biothermoplastic composites is greatly influenced by many factors including temperature and molding time. This study aims to determine the effect of molding temperature and time on the characteristics of tray packaging from thermoplastic starch, thermoplastic glucomannan and latic polyacud biothermoplastic composite raw materials. This study used a 2-factor with 9 treatments, each treatment repeated as many as 2. The first factor is temperature (S) which consists of 3 temperature levels 130  (S1), 145  (S2), 160  (S3). The second factor is time (W) which consists of 3 levels of 30 seconds (W1), 45 seconds (W2), 60 seconds (W3). The results showed that temperature and molding time significantly affected the tensile strength, elongation at break, elasticity, thickness development, density, biodegradation time and leakage test of TPS/TPG/PLA biothermoplastic composite tray packaging. The best tray packaging was obtained at molding with a temperature of 160 ℃ and a time of 45 seconds with a tensile strength value of 42.20  MPa, elongation at break value of 0.70%, modulus young of 6, 12 GPa, swelling of 0.47%, density of 1.31 g/cm3, biodegradation time of 24.00 days and leakage test (not leak). However, modulus young, elongation at break and density have not met the standards set.

Abstract

This study aims to analyze the performance enhancement of an induced draft cooling tower through modifications to the water distribution piping line, as well as to evaluate the thermal and hydraulic performance before and after modification. The initial system exhibited relatively low cooling effectiveness due to uneven water distribution and limited heat transfer between air and water within the tower. Therefore, the piping layout was redesigned to improve flow uniformity, enlarge the air–water contact area, and minimize heat losses, thereby enhancing overall cooling efficiency. The experimental tests were conducted under identical operating conditions with an inlet water temperature of 38 °C. The results showed that the outlet water temperature decreased from 33.78 °C (before modification) to 28.95 °C (after modification). The range increased from 5.17 °C to 9.12 °C, while the approach decreased from 4.68 °C to 2.61 °C, indicating a more effective cooling process approaching ideal conditions. Furthermore, the cooling capacity showed a substantial increase from 21,717.4 kW to 61,515.1 kW, signifying that the modified cooling tower can dissipate a greater amount of heat and support higher cooling demands in industrial operations. In addition, the system effectiveness improved from 52.45% to 77.58%, demonstrating a significant enhancement in heat transfer efficiency as a result of improved fluid distribution. On the other hand, the total head loss increased from 39.11 m to 63.71 m, indicating higher flow resistance due to the new configuration, but it remained within acceptable limits. Overall, the study concludes that modifying the piping line in the induced draft cooling tower significantly improves thermal performance, cooling effectiveness, and capacity, making the redesigned configuration a viable approach to increase the efficiency of large-scale industrial cooling systems..

Abstract

Biotermoplastic is a one of the innovation to improve the physical and mechanical properties of bioplastics. This study aims to determine the effect of the type and concentration of compatibilizer on the characteristics of biothermoplastic composites and to determine the type and concentration of the right compatibilizer to produce the best characteristics of biothermoplastic composites of thermoplastic starch/thermoplastic glucomannan/polylactic acid (TPS/TPG/PLA). This research utilizes a Completely Randomized Design (CRD) with 6 treatments, namely J1KI (maleic acid anhydride 5%), J1K2 (maleic acid anhydride 7,5%), J1K2 (maleic acid anhydride 10%), J2K1 (stearic acid 5%), J2K2 (stearic acid 7,5%), and J2K3 (stearic acid 10%), with 3 replications. The variables observed in this study were tensile strength, elongation at break, elasticity, swelling, density, melting point and biodegradation time. The data were analyzed by analysis of variance (ANOVA) and further tested using the Honestly Significant Difference (HSD) test. The results showed that the type and concentration of compatibilizer had a very significant effect on the values ​​of tensile strength, elongation at break, elasticity, swelling, density, melting point and biodegradation time. The best characteristics of biothermoplastic composites of thermoplastic starch/thermoplastic glucomannan/polylactic acid were obtained by using 10% anhydrous maleic acid compatibilizer with a tensile strength value of 30.43 MPa, an elongation at break of 0.90%, elasticity of 3.38 GPa, swelling of 0.51%, density of 1.52 g/cm3, melting point of 149.77oC and biodegradation time of 17.667 days.

Abstract

Determination of biothermoplastic composite formulation is essential to produce the best biothermoplastic composite characteristics and meet the standards. This study seeks to identify the characteristics of the best biothermoplastic composites in variations of thermoplastic starch formulations, thermoplastic glucomannan and polylactic acid. This study used a Completely Randomized Design (CRD) with 5 treatments of TPS/TPG formulas with PLA, namely 90:10, 80:20, 70:30, 60:40, 50:50. There were 4 repetitions of each treatment, for a total of 20 experimental units. The variables observed were tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density. The diversity analysis showed that the formulation of thermoplastic starch-thermoplastic glucomannan and polylactic acid had a very significant effect on the tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density of biothermoplastic composites. Biothermoplastic composites with the formulation of TPS/TPG: PLA = 50:50 produced the best characteristics with a tensile strength of 26.71 MPa, elasticity of 932.04 MPa, elongation at break of 2.89%, biodegradation of 15.25 days, melting point of 152.65oC, density of 1.26 g/cm3 and swelling of 1.32%.

Abstract

Pemantauan parameter penyinaran matahari sebagai pemicu evaporasi di Waduk Jatiluhur masih menggunakan Sunshine Recorder Campbell Stokes yang memiliki kelemahan mendasar, yaitu ketidakakuratan data, subjektivitas pembacaan manual, serta tidak adanya pencatatan parameter pendukung seperti suhu lingkungan. Kondisi ini menyebabkan data evaporasi yang dihasilkan kurang komprehensif dan tidak cukup reliabel untuk mendukung manajemen waduk secara optimal. Penelitian ini bertujuan mengembangkan sistem pemantauan intensitas cahaya matahari berbasis Internet of Things (IoT) yang mampu merekam data secara komprehensif, meliputi intensitas cahaya, durasi penyinaran efektif, suhu lingkungan, serta waktu pengukuran secara real-time dengan akurasi tinggi dan objektif. Sistem data logger dikembangkan menggunakan sensor BH1750FVI untuk mengukur intensitas cahaya, modul RTC DS3231 untuk pencatatan waktu presisi sekaligus suhu lingkungan, ESP32 sebagai pengendali utama dan modul SD Card sebagai penyimpanan cadangan saat jaringan internet mengalami gangguan. Protokol MQTT digunakan untuk pengiriman data ke cloud, sedangkan bot Telegram diintegrasikan untuk menyajikan data secara langsung. Hasil pengujian menunjukkan bahwa alat berhasil merekam keempat parameter kunci secara simultan dan akurat. Sensor BH1750FVI dan RTC DS3231 menunjukkan kinerja yang stabil dan presisi. Sistem ini terbukti mampu mengatasi keterbatasan Campbell Stokes dengan menghasilkan data yang objektif, tercatat pada bot Telegram, tersimpan di SD Card dan Google Sheet, serta terkirim melalui MQTT. Dengan demikian, sistem ini memberikan solusi pemantauan evaporasi yang komprehensif, real-time, dan andal untuk mendukung pengelolaan Waduk Jatiluhur secara lebih efektif.
