Abstract

Ubi jalar (Ipomoea batatas) merupakan tanaman pangan alternatif atau pengganti beras yang telah lama dikenal dan digemari oleh masyarakat. Hama penggerek batang merupakan salah satu hama utama yang dirasakan merugikannya. Bagaimana tingkat kerusakannya pada dua cara tanam belum banyak laporannya. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana tingkat kerusakan yang diakibatkan oleh hama penggerek batang pada dua cara tanam Penelitian dilakukan di lahan sawah dengan percobaan lapangan. Percobaan dirancang dengan rancangan acak kelompok dengan dua perlakuan yaitu cara tanaman dalam karung (K) dan kontrol dalam bedengan tanah (C). Masing-masing Perlakuan diulang sebanyak enam kali (blok) dan setiap blok ditanam 4 stek ubi jalar klon tailan. Secara keseluruhan diperoleh 12 petak percobaan yang terdiri dari masing-masing petak ada empat stek klon ubi jalar. Hasil penelitian menunjukkan bahwa Cara tanam biasa (kontrol) diserang oleh tiga spesies serangga penggerek batang yaitu Omphisa Anastomosalis (Lepidoptera: Pyralidae), Cylas Formicarius (Coleoptera: Curculionidae) dan Oberea sp. (Coleoptera: Cerambycidae). Cara tanam dengan wadah karung hanya diserang oleh dua spesies serangga hama, yaitu Omphisa Anastomosalis (Lepidoptera: Pyralidae), dan Oberea sp. (Coleoptera: Cerambycidae). Intensitas kerusakan yang ditimbulkan oleh ketiga serangga hama penggerek batang di cara tanam dalam karung (30,92±7,44%) lebih kecil dibandingkan dengan kontrol sebesar (42,94±4,70%).

Abstract

Mercury is one of the heavy metals that has the highest toxicity in the global environment. Mercury can cause environmental damage and if it enters the food chain it can have negative impacts on human health. In overcoming the problem of mercury entering the food chain, it is very important to study the mobility and distribution of mercury in the soil. The presence of mercury (Hg2+) in soil is largely controlled by adsorption reactions with certain specific adsorption patterns. Therefore, it is very important to study mercury adsorption on several different types of soil in order to get an idea of ​​how adsorption occurs in West Sumbawa Regency. The aim of this research is to determine the pattern and capacity of mercury adsorption on various large groups of soil in West Sumbawa Regency and the relationship between soil properties and mercury adsorption. The results of the research show that the adsorption isotherm pattern in the great soil groups Endoaquepts, Ustipsamments, and Udorthents more closely follows the Langmuir adsorption model, while the great soil groups Haplustepts, Hapludolls, Eutrudepts and Ustifluvents follow the Freundlich adsorption model. The major soil group that has the highest maximum mercury adsorption capacity in West Sumbawa Regency is Endoaquepts at 4,604 mg/g.

Abstract

This research investigates the effect of soil amendments in the form of cow, form goat manures and PGPR biofertilizer on cotton plants intercropped with corn in the dry lands of North Lombok Regency. The research aims is to determine the growth and yield response of cotton plants due to the application of soil amendments and PGPR in an intercropped system with corn in dryland areas. The research was conducted from December 2023 to June 2024 in Andalan Village, Bayan District, North Lombok Regency. The method used is an experimental method with field trials. The design used was Randomized Block Design (RBD), incorporating two factors: soil amendment treatment (P) as the main plot and PGPR (K) concentration treatments as the subplot. Soil amendments consisted of three levels: P0 (no cow manure and no goat manure), P1 (20 tons/ha cow manure), P2 (20 tons/ha goat manure). PGPR concentration consisted of four levels: K0 (without PGPR), K1 (20 ml/liter PGPR application), K2 (30 ml/liter PGPR application), and K3 (40 ml/liter PGPR application). The research results indicated that the application of 20 tons/ha of goat manure (P2) produced the highest average across all observed parameters (plant height, number of leaves, branch number, stem diameter, and plant yield). Similarly, the application of 40 ml/liter PGPR produced the highest average for these observed parameters. Based on the results of the land equivalent ratio (LER) analysis, this integration system shows highly suitable and relevant to be applied in the dry lands of North Lombok.

Abstract

This research discusses the application of the balance principle in laboratory waste management as a strategy to minimize environmental impacts. This principle aims to balance laboratory activities and environmental protection by reducing waste at the source, sorting it out, and using environmentally friendly waste processing technology. The research used a descriptive qualitative approach in the Mataram University laboratory. The research results show that applying the balance principle is still not optimal due to limited understanding, infrastructure and adequate policy support. Recommended strategies include implementing the 3R principle (Reduce, Reuse, Recycle), selecting safer chemicals, and increasing training and preparing clear SOPs. Waste identification reached (50%), with limitations in storage (44%) and transportation (43%). Management and final disposal were minimal (33% and 38%), increasing environmental risks. Documentation, reporting (43%), and regulatory compliance (43%) still need to be improved. The K3 aspect is quite good (54%), but emergency response procedures are still weak. Sustainable management (37%) and environmental monitoring (43%) lack effort in mitigating environmental impacts. Applying the principle of balance is important to achieve sustainable laboratory waste management.

Abstract

One of the primary challenges in rice cultivation is the disturbance caused by pest infestations. Among the pests that frequently cause damage to rice plants is the white rice stem borer (Scirpophaga innotata). The life cycle of Scirpophaga innotata comprises egg, larva, pupa, and adult stages. This article is based on a literature review and discusses the natural enemies most commonly encountered at each stage of the Scirpophaga innotata life cycle. The findings of this article can be summarized as follows: Natural enemies of the white rice stem borer during the egg stage include parasitoids such as Trichogramma japonicum Ashm., Tetrastichus schoenobii, and Telenomus rowani, as well as the predator Conocephalus sp. During the larva-pupa stage, parasitoids such as Apantheles sp., Bracon sp., Tropobracon sp., and Temelucha bigutella are present, along with predators like Miscrapis crocea and Harmonia octomaculata. Regarding the adult stage, parasitoids were not found to be natural enemies of adult S. innotata. However, the most commonly encountered predators include Coccinella transversalis (Thunberg) and Paederus sp.

Abstract

Edamame (Glycine max (L.) Merril) is a legume commodity with high economic potential, and its production demand continues to increase in both domestic and export markets. However, edamame productivity is often constrained by pest attacks (OPT) such as Spodoptera litura, Etiella zinckenella, Riptortus linearis, and other major pests. In this study, the presence of spider predators in edamame plants was examined in relation to different concentrations of a botanical pesticide derived from paitan leaves (Tithonia diversifolia). Using a Randomized Block Design (RBD) with six treatments (P0, control), P1, P2, P3, P4, and P5, each with four replications, the study was place in Sembalun Village, East Lombok Regency, from May to July 2024. Three indices—the dominance index, the abundance index, and the Shannon-Wiener diversity index (H')—were used to evaluate the data. The results showed 6 spider genera from 5 families, with Pardosa and Pirata being the most dominant. The highest population was found in the control (P0) and decreased with increasing pesticide concentration. The highest diversity index was at P0 (H’=1.382) and the lowest at P5 (H’=1.222), with the evenness index categorized as moderate and the highest dominance index at P2 (0.372). In conclusion, higher concentrations of paitan leaf extract reduced the presence of spider predators, indicating that its application should consider appropriate doses to avoid harming natural enemies.

Abstract

The use of natural enemies as pest control has long been known, but has been largely replaced by the rapid development of chemical pesticide industry technology, especially since the green revolution. One alternative pest control technology that is quite promising to be developed is the use of biological agents (predators or parasotoids) that have more natural characteristics than chemical characteristics. With the presence of natural enemies which are then used to suppress pest populations, it will be safe for human health and the environment. It can be hoped that the agricultural products produced will be acceptable and highly competitive on the global market. Considering the Sembalun area as a tourism destination, it will be very relevant if the local community understands good horticultural practices. The intervention of using technology for farmers as an alternative in good Horticultural Cultivation is highly expected by farmers in the Sembalun area. Therefore, assistance is needed to implement integrated Pest Management in good Horticultural practices. The method used in this activity is the Action Research Method by applying a Participatory Action Program approach from participants through discussion and group work in all activities. The result is that farmers are very interested in implementing good horticultural cultivation, especially with habitat management approaches such as using refugia plants to control pests. Participating farmers increase their knowledge and skills to recognize differences in pests and natural enemies (predators and parasitoids) found on potato plants that are integrated with refugia plants. The target group has increased knowledge and understanding of the importance of implementing Integrated Pest Management (IPM) practices in horticultural cultivation. It is hoped that training and assistance activities for healthy horticultural cultivation efforts will continue both by the university team and related agencies. This kind of activity needs to be continued by the participating group and spread to other groups nearby. There is a need for assistance in applying for Prima 3 and Prima 2 food safety certification to farmer groups in the Sembalun Agrotourism Area, so that the number of products from certified horticultural business actors will increase. Activities to implement Integrated Pest Management in horticultural farming business groups in the Sembalun Tourism Area need to continue
