Abstract

Aloe vera ekstract is an ingredient that has many benefits, but currently there is no specific research on the use of aloe vera juice in making Greek yogurt. This study aims to determine the effect of variations in incubation temperature on the physicochemical properties of Greek yogurt with the addition of aloe vera ektract. The design used in this study is a non-factorial completely randomized design with 3 treatments and 5 replications. The treatment consists of P1 = incubation temperature 43°C, P2 = incubation temperature 46°C, and P3 = incubation temperature 49°C. The parameters observed include viscosity, yield, pH, water content, protein content, and fat content. The results showed that differences in incubation temperature had a significant effect (P < 0.01) on the value of viscosity, yield, pH, water content, and fat content but did not significantly affect the protein content of Greek yogurt with aloe vera extract, which was 8.85% - 8.95%. The best treatment was found in P3, namely an incubation temperature of 49°C.

Abstract

Melon (Cucumis melo L.) is a high-economic-value horticultural commodity whose production success greatly depends on optimal early vegetative growth. Melon seedlings transplanted late are prone to physiological stress that can hinder vegetative development, requiring strategies to support plant adaptation. This study serves as a preliminary research to assess the effectiveness of the recommended dosage of 1% on the vegetative growth of delayed transplanted melon seedlings (16 days after sowing). The experiment was conducted with two treatments: no biostimulant application as control (P0) and 1% biostimulant application (P1), each with 16 replications, resulting in a total of 32 experimental units. Observed parameters included plant height, leaf number, stem diameter, and internode length at 7, 14, and 21 days after transplanting (DAT). The t-test results showed that biostimulant application had no significant effect (p<0.05) on all observed variables through the end of the vegetative phase. This study indicates that applying biostimulant at a 1% concentration was ineffective in restoring vegetative growth in delayed-transplant melon seedlings, suggesting the need for further research with different doses and application frequencies.

Abstract

The Special Purpose Forest Area of the University of Muhammadiyah Mataram has the potential to be a location for education and biodiversity conservation. This study aims to analyze diversity, species richness, and evenness of vegetation as indicators of forest ecosystem conditions. The study was conducted in June 2025 using a quantitative descriptive approach in 16 observation plots across four growth strata. The analysis was carried out using the Shannon-Wiener index for diversity, Margalef for species richness, and Pielou for evenness. The results showed that the tree stratum had a value of H' = 2.703, R = 5.951, and E = 0.780, reflecting a vegetation community with high and even diversity and distribution of individuals. In contrast, the seedling stratum showed very low values of H' = 0.049, R = 1.443, and E = 0.071, indicating the dominance of certain species and limited natural regeneration. Overall, 44 species from 24 families with a total of 236 individuals were identified. This pattern indicates an unbalanced vegetation structure across strata, with higher community stability at the tree level compared to younger growth levels. This finding provides a scientific basis for sustainable forest management and conservation planning.

Abstract

The increasing generation of palm oil waste poses a serious challenge as it can cause environmental pollution if left unutilized. One environmentally friendly solution is to convert palm oil waste into organic fertilizer through maggot bioconversion. This study aimed to mitigate environmental impacts by converting palm oil waste into organic fertilizer using Black Soldier Fly (BSF) larvae and to evaluate its effects on the growth of pakcoy (Brassica rapa L.). The experiment was conducted in Tepian Batang Village, Paser Regency, East Kalimantan, using a two-factor randomized block design with three kasgot (maggot compost) doses (40 g, 80 g, 120 g) and three types of palm oil waste-based growing media (empty fruit bunches, decomposed fronds, and palm ash), each applied at 150 g. Growth parameters observed included plant height, number of leaves, fresh weight, and dry weight of pakcoy. The results showed that the combination of 80 g kasgot and 150 g decomposed fronds (K2M2) increased plant height to 3.67 cm (↑11% compared to the overall mean), leaf number to 10.40 (↑15%), and fresh and dry weight to 47.75 g (↑28%). This combination proved most effective in accelerating vegetative growth of pakcoy. These findings highlight the potential of utilizing palm oil waste as a high-quality organic fertilizer to support sustainable agriculture and circular economy initiatives.

Abstract

Dry land with low rainfall results in minimal availability of irrigation water. However, the lack of irrigation water is not an obstacle in cultivation if the right, effective and efficient irrigation method is applied, namely drip irrigation. This study aims to see the effect of applying drip irrigation techniques with different water discharge treatments on tomato plant growth. This research was conducted in Batu Putik Village, East Lombok Regency from August 12, 2020 to September 20, 2020. This research method uses experimental methods by conducting direct experiments in the field. This study used a Completely Randomized Design (CRD) with 3 treatments 4 times repeated so that 12 experimental units were obtained. Each treatment was P1 with a 90° tap slope discharge, P2 with a 45° tap slope discharge, and P3 with a 15° tap slope discharge. The research data were analyzed using ANOVA. The results of the drip irrigation technique design performance test showed an average uniformity coefficient percentage of 94% in all treatments. The results of this test provide an insignificant effect on plant height, stem diameter, and number of leaves of tomato plants. So this insignificant result shows that the application in the field in relation to water efficiency should use P1 with less water distribution but gives the same effect as P2, and P3 on tomato plant growth. While in wet and dry stems, there is a significant effect between treatments.

Abstract

Sweet potato (Ipomoea batatas L.) is a staple food commodity in Wamena, Papua Highlands, yet its productivity has declined due to pest infestations. This study aimed to identify the infestation of Cylas formicarius (sweet potato weevil) and analyze its impact on yield quality and quantity. Field surveys were conducted using a cross-sectional observational design, morphological identification of pests, and descriptive analysis of leaf, stem, and tuber damage. Results revealed that C. formicarius was the predominant pest, characterized by leaf perforations, stem cracks, and decayed tubers containing larvae. Such damage significantly reduced harvest quality and quantity, rendering tubers unsuitable for consumption and storage. The discussion highlights that humid environmental conditions and traditional farming practices increase infestation risks. In conclusion, C. formicarius poses a serious threat to sustainable sweet potato production in Wamena, thus requiring urgent ecological interventions. Recommended strategies include implementing ecologically based integrated pest management, such as crop rotation, the use of local botanical insecticides, pheromone traps, and farmer education.

Abstract

Agricultural wastes such as cocoa shells and groundnut shells hold significant potential as environmentally friendly alternative energy sources, particularly in West Nusa Tenggara Province, where these commodities are produced in abundance. However, their utilization as biomass energy materials remains limited and underdeveloped. In response to this potential, this study aims to evaluate the effect of varying tapioca starch adhesive concentrations on the characteristics of briquettes made from a mixture of cocoa shell charcoal and peanut shells. The research was conducted experimentally using three adhesive concentrations (10%, 20%, and 30%), with tests performed on calorific value, moisture content, ash content, and flame duration. The results revealed that increasing the adhesive concentration tended to decrease the calorific value and increase both the moisture and ash contents, although it extended the flame duration. The briquettes with 10% adhesive concentration exhibited the best performance, achieving a calorific value of 5,310 cal/g, a moisture content of 7.57%, an ash content of 7.56%, and a flame duration of 73 minutes. These values comply with the Indonesian National Standard (SNI) for charcoal briquettes, which require a minimum calorific value of 5,000 cal/g, a maximum moisture content of 8%, and a maximum ash content of 8%. These findings highlight the importance of proper adhesive formulation to improve the quality of local biomass-based briquettes and support the transition toward clean and sustainable energy..

Abstract

Bananas are one of the important commodities produced by Indonesian farmers. These commodities are mostly sold in raw form or as perishable products, resulting in relatively low economic value. The development of a processing industry is important to extend the shelf life of products and increase added value at every stage of the production chain. This study aims to analyse the added value of processed banana products in North Batukliang District. The research approach used is descriptive, with the aim of providing a systematic description of the issues under study. The research objects include banana processing businesses that play a role in creating added value in the region. Respondents were selected using snowball sampling because the population size was not known with certainty. The data were analysed using the Hayami value-added method to obtain comprehensive results. The results showed that banana sale products generated added value of IDR 10,484/kg of raw materials, which was higher than banana chips, which had a value of IDR 3,278/kg of raw materials. The added value ratio generated is 68% for banana chips and 46% for banana chips. These findings indicate that increasing the production of banana chips can be a more profitable strategy for businesses because it provides higher economic added value and supports the development of local agro-industry. This study recommends that businesses increase the scale of banana chip production to optimise profits.

Abstract

Mikro serat (holoselulosa) dari serat batang pohon nunang memiliki karakteristik mekanik, ketahanan panas yang baik dan densitas ringan sehingga cocok untuk material kemasan hasil pertanian (biokomposit). Lembaran serat nunang diperoleh dengan merendam kulit batang nunang dalam air dan dipotong ±1 cm untuk diblender, dan dilanjutkan proses pengayakan 40 mesh. Serat makro nunang kemudian diputihkan dengan larutan NaClO2 5% dan dimerserisasi dengan larutan NaOH 9% pada suhu 65 °C dan kecepatan 500 rpm selama 2 jam di atas magnetic stirrer. Hasil uji FTIR mengungkapkan telah hilangnya serapan pada bilangan gelombang 2026–1698 cm-1 yang merupakan indikasi hilangnya senyawa lignin, hemiselulosa, lilin dan senyawa pengotor lainnya. Pengujian difraksi sinar-X (XRD) menunjukkan niilai indeks kekristalan yang lebih tinggi setelah perlakuan kimia NaClO2 dan NaOH, sementara itu pengamatan foto SEM menunjukkan fitur permukaan yang lebih kasar sebagai tanda larutnya material pengotor. Setelah perlakuan kimia serat mikro juga mengindikasikan ketahanan termal yang lebih tinggi. Penelitian ini menunjukkan bahwa serat mikro nunang setelah perlakuan kimia memiliki potensi untuk industri kemasan hasil pertanian seperti film transparan ataupun bioplastik.

Abstract

Sumbawa is known as a cow's milk producing area in West Nusa Tenggara Province. Unfortunately, the use of Sumbawa cow's milk is limited to milk candy products. In fact, the potential for dairy processing is very diverse, one of which is the typical synbiotic cheese product from Sumbawa. This study aims to analyze the effect of prebiotic types on the physical characteristics and organoleptic tests (level of liking) of typical Sumbawa synbiotic cheese products. The physical characteristics tested include pH and color, while the organoleptic test includes taste, aroma, texture and color. This research is experimental in nature by conducting experiments in the laboratory, using a completely randomized design with one factor, namely the type of prebiotic. The types of prebiotics used are uwi flour, seaweed flour and soybean flour. The three types of prebiotics used gave pH test results ranging from 5.82-5.90. The resulting pH value did not have a significant effect on the type of prebiotic used. Analysis of the physical properties of color obtained a range of L values of 76-80, a values of 0-3, b 7-19, Hue 69-90, and ∆E 12.13-3.37 from all treatments. The results of the color analysis showed that all samples were in quadrant one, which indicates that the cheese was yellow with varying intensities. Cheese with prebiotic soy flour is more yellow than prebiotic uwi flour and seaweed. The prebiotic type of cheese product made from yam flour had a significant effect on the color test results, while the organoleptic test results showed that the prebiotic type of yam flour and seaweed flour samples were the most popular in terms of taste, aroma and texture. When compared to the three treatments, cheese made from seaweed flour had the best level of acceptance. The potential for developing synbiotic cheese in the Sumbawa region is very large to produce products that can be accepted by the wider community.
