Abstract

Proses pemasakan dan kristalisasi gula semut, selama ini masih dilakukan dengan metode konvensional. Metode tersebut memiliki kelemahan karena gula yang dihasilkan mengandung kadar air yang tinggi dan memerlukan waktu untuk proses pembuatan yang lama. Tujuan dari penelitian ini adalah memodifikasi dan menganalisis mesin semi otomatis gula semut untuk menghasilkan gula semut dengan kadar air yang lebih rendah. Alat yang digunakan adalah Mesin Pemasak Semi Otomatis Gula Semut. Perlakuan pada penelitian ini terdiri dari frekuensi dan kecepatan pengaduk. Perlakuan kontrol mesin meliputi kecepatan pengaduk dengan penambahan inverter, alat pengaduk, blower (pengganti kipas), dan alat penggerus dengan perlakuan pengaturan 3 (tiga) frekuensi yaitu 20 Hz, 30 Hz, dan 40 Hz dan kecepatan putaran alat pengaduk yaitu 12 rpm, 18 rpm dan 24 rpm. Kedua perlakuan dilakukan pengulangan sebanyak 3 (tiga) kali. Pengujian mesin menggunakan bahan baku nira kelapa sebanyak 20 l. Peubah dilakukan dengan memperhitungkan penurunan kadar air, kecepatan pengaduk, torsi, kecepatan bahan bakar (LPG), dan biaya listrik. Modifikasi mesin pemasak semi otomatis dengan perubahan kipas menjadi blower dan penambahan inverter menghasilkan durasi pemasakan yang lebih cepat dibanding mesin pemasak sebelum modifikasi. Waktu yang digunakan mesin pemasak setelah modifikasi adalah 119,7 menit pada proses evaporasi dan 12 menit pada proses kristalisasi, sedangkan sebelum modifikasi, waktu yang digunakan untuk proses evaporasi adalah 150 menit dan 40 menit pada proses kristalisasi. Kadar air yang dihasilkan setelah modifikasi berkisar 2,17 – 2,81 % sedangkan sebelum modifikasi 2,96 – 4,56 %. Selain itu, ukuran partikel gula semut yang dihasilkan jauh lebih seragam dimandingkan dengan mesin pemasak sebelum modifikasi (berbentuk bongkahan).

Abstract

Biodegradable pots made from biomass waste offer an environmentally friendly alternative to replace plastic polybags in plant cultivation. This study aimed to evaluate the effect of different raw materials used in making biodegradable pots on the vegetative growth of chili pepper plants. Two treatments were applied: pots made from Kepok banana stem fibers (B1) and pots made from rice straw (B2), each with four replications. The observed parameters included root length, plant height, stem diameter, and number of leaves over 27 days after planting. The results showed that pots made from rice straw produced better growth in all parameters compared to those made from banana stem fibers. The longest root length was found in treatment B2U1 (19 cm), the tallest plants in B2U2 (23.6 cm), and the largest stem diameter also in B2U2 (0.37 cm). These differences are attributed to the physical characteristics of the raw materials: rice straw pots have lower density and a porous structure that facilitates root penetration and growth, while banana stem pots have higher density and fiber mass, resulting in a denser structure that restricts root development. Therefore, it can be concluded that biodegradable pots made from rice straw are more effective in supporting the vegetative growth of chili pepper plants than those made from banana stem fibers. Keywords: Banana Stem, Biodegradable Pot, Densities, Kepok Banana Stem, Rice Straw, Vegetative Phase.

Abstract

The high volume of fruit waste in Lampung and Indonesia in general requires environmentally friendly waste management solutions. This study aims to utilize such waste for liquid organic fertilizer by evaluating the effects of mixing fruit waste-based liquid organic fertilizer (LOF) with AB Mix nutrients on the growth of red spinach (Alternanthera amoena Voss) in a Static Aerated Technique (SAT) hydroponic system. The research employed a Completely Randomized Design (CRD) with a single factor, consisting of five treatment combinations of LOF and AB Mix concentrations (0–100%) and three replications. Observed parameters included plant height, number of leaves, plant weight, root length and weight, stem diameter, and water use efficiency. The results showed that the use of pure AB Mix (100%) produced the best growth outcomes compared to the mixed or pure LOF treatments. The lower growth and productivity in the LOF treatments were attributed to the low levels of macronutrients (N, P, K) in the produced LOF, as well as the presence of sediment that hindered nutrient absorption and the upward flow of nutrient solution from the reservoir to the plant root zone. Nevertheless, the combination of LOF and AB Mix still shows potential as an alternative nutrient source for hydroponic cultivation if optimally formulated.  Keywords:  AB Mix, Fruit Waste, Liquid Organic Fertilizer, Red Spinach, SAT Hydroponics,

Abstract

Crude palm oil (CPO) productivity in Central Lampung Regency, at 2.25 tons/ha/year, remains below the national average of 3.90 tons/ha/year. One of the contributing factors is that oil palm plants are not growing optimally. This is reflected by the fact that the canopy cover is not dense or uniform. The objective of this study was to assess the dense or crown of oil palm trees using remote sensing technology from satellite imagery. In this study, Sentinel-2 imagery was used to oil palm canopy closure, and Landsat 8 imagery was used for land suitability analysis. The research method includes the vegetation index analysis by Normalized Difference Vegetation Index (NDVI), land moisture index by the Normalized Difference Moisture Index (NDMI), Land Surface Temperature (LST), and land suitability parameters. The results of the analysis are then macthed with the conditions of oil palm plants in the field. The results obtained from this study indicate that oil palm plantations in the Bekri District can be categorised into two discrete classes: Class S2 (sufficiently suitable) and Class S3 (marginally suitable). The total area encompassed by these classes is 8,903 hectares, with Class S2 covering 7,615 hectares and Class S3 covering 218 hectares. Moreover, the study revealed that 3,721 hectares were conducive to optimal plant growth with a dense crown, 765 hectares exhibited normal crown and growth, and 310 hectares displayed suboptimal growth with an indicated uniform dense crown. The overall accuracy rate of the study is 81.82%. There is a positive correlation between NDVI and NDMI values with a correlation coefficient (R2) of 0.8426, but there is a negative correlation between the NDVI and LST values with a correlation coefficient of -0.586.

Abstract

Background: Energy demand continues to increase along with population growth and human activities, while the availability of fossil energy in Indonesia is becoming increasingly limited. On the other hand, agricultural biomass wastes such as cassava stems, bamboo stems, coconut shells, and corn cobs are abundantly available but have not yet been optimally utilized as alternative energy sources.Aims: The aim of this research is to to evaluate the effect of combining biomass wastes of cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder on the physical characteristics and energy value of biobriquettes, as well as to assess their conformity with briquette quality standards as an alternative fuel.Methods: This study produced biobriquettes from cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder with two concentrations (7% and 10%). The biobriquettes were evaluated for physical and energy characteristics, including density, moisture content, compressive strength, shatter resistance index, calorific value, and burning rate, following SNI 01-6235-2000.Result: Evaluation of biobriquette quality based on SNI 01-6235-2000 shows that all treatments meet the requirements for density, moisture content, and Shatter Resistance Index, indicating good physical quality and mechanical durability. For calorific value, only treatments P2T1, P2T2, P3T1, and P3T2 meet the minimum SNI standard (? 5,000 cal/g), while P1T1 and P1T2 do not. Overall, the biobriquettes produced have the potential to comply with SNI 01-6235-2000 as an alternative fuel, although optimization of biomass composition is still needed to improve calorific value.Conclusion: The combination of cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder was able to produce biobriquettes suitable as an alternative fuel. Treatments P2 and P3, particularly with a 7% binder concentration, met the calorific value requirement of SNI 01-6235-2000, indicating that a lower tapioca binder concentration is more effective and has strong potential for development as a renewable energy source based on biomass waste.

Abstract

Sandy soil is characterized by a high infiltration rate and low water retention capacity, making it less effective in supplying water for plant growth. This study aimed to analyze the effect of rice husk biochar application on infiltration and water retention capacity in sandy soil. The experiment was conducted from July to August 2024 at the Greenhouse of the Department of Agricultural Engineering, Faculty of Agriculture, University of Lampung. Four treatments were applied: A1 (0% biochar), A2 (10%), A3 (15%), and A4 (20%), each replicated three times. Observed parameters included soil moisture content, infiltration rate, water holding capacity, and the duration of water content change. Results indicated that rice husk biochar addition reduced the infiltration rate of sandy soil, with the lowest value observed in A4 (20%) at 6.42 mm/hour compared to the control A1 (0%) at 7.89 mm/hour. The time required for soil moisture to decrease from 14% to 8% was shortest in A1 (96 hours) and longest in A4 (456 hours). It can be concluded that rice husk biochar enhances the water retention ability of sandy soil and slows down moisture loss, with the 20% dose being the most effective treatment in improving water holding capacity.
