Abstract

Insecticides are a type of pesticide that is commonly used by farmers to eradicate insect pests, one of which is the stink bug. Excessive use results in resistance and contamination of soil, water, and air. Another alternative is bioinsecticides which are safe and do not cause resistance. In this study, the samples used were gadung and bintaro root extracts. The method used is maceration, after the maceration process, the filtrate will be tested on the target animal, looking for the best insecticide mortality and screening for phytochemicals. Lastly, the best bioinsecticide solutions were identified using FT-IR and UV-Vis spectrophotometers. The best bioinsecticide solutions with 60% and 40% mortality were bioinsecticides with a concentration of 70% gadung and 30% gadung 20% bintaro. Phytochemical screening tests were carried out on both of them, the results were positive for terpenoids and alkaloids. Identification using the FTIR spectrophotometer showed that the bioinsecticide solution contained secondary metabolites with O-H groups appearing at absorption wave number 3260 cm-1, C=O groups appearing at wave number 1637cm-1,, and C-H groups appearing at wave number 1359 cm-1. The results of the UV-Vis spectrum showed that the bioinsecticide solution had the C=C functional group as indicated by the appearance of peaks at a wavelength of 210 nm, 217 nm, and 223 nm.

Abstract

ABSTRAK KWT Bungsu Cantik merupakan salah satu kelompok wanita tani yang berada di kelurahan Penengahan Raya, Kota Bandar Lampung memiliki potensi sumberdaya manusia (SDM) yang dapat memiliki kontribusi terhadap keberlanjutan lingkungan melalui kegiatan pengolahan sampah. Namun saat ini kegiatan pengolahan sampah masih belum dikelola secara optimal karena masih kurangnya pemahaman mengenai pemilahan sampah, pembuatan sampah organik dan pemasaran produk kompos. Tujuan dari kegiatan pengabdian adalah membantu meningkatkan semangat dan kemampuan mitra untuk melakukan pemilahan sampah yang masih bisa dimanfaatkan kembali, membantu mengurangi permasalahan sampah yang terdapat di lingkungan mitra, dan memberikan pengetahuan kepada mitra mengenai aplikasi digital penjualan produk olahan dari sampah. Pelaksanaan PKM terdiri dari beberapa kegiatan. Kegiatan pertama adalah penyuluhan Penyuluhan Pemilahan Sampah Dan Pembuatan Kompos. Kedua, kegiatan Pemanfaatan Aplikasi Digital Dalam Pemasaran Produk. Terjadi peningkatan pengetahuan peserta setelah dilakukan PKM yang artinya kegiatan ini dapat memberikan manfaat bagi peserta sehingga peserta memahami pentingnya pengolahan sampah dan dapat membuat pupuk kompos yang bisa dimanfaatkan untuk pupuk pada tanaman perkarangan, kebun maupun untuk dijual. Peserta juga dapat menggunakan aplikasi Jual Beli Sampah sehingga memudahkan dalam pemasaran produk. Kata Kunci: Aplikasi Digital, Kelompok Wanita Tani, Kompos, Sampah  ABSTRACT KWT Bungsu Cantik is a group of women farmers in the Penengahan Raya sub-district, Bandar Lampung City, which has the potential for human resources (HR) who can contribute to environmental goals through waste processing activities. However, these activities are currently not managed optimally due to a lack of understanding regarding waste sorting, organic waste processing, and compost product marketing. The service activities aim to increase partner’s enthusiasm and ability to short reusable waste, reduce waste problems in the partner environment, and provide knowledge to partners regarding digital applications for marketing waste-processed products. The implementation of PKM consists of several activities. The first is education on Waste Sorting and Compost Making. The second focuses on using digital applications for product marketing. There was an increase in participants' knowledge after PKM was carried out, indicating this program benefits by enhancing their understanding of waste processing and compost production that can be used as fertilizer for yard plants, gardens, or sold. Additionally, participants are now able to use a Trash Buying and Selling application to facilitate product marketing.  Keywords: Compost, Digital Applications, Waste, Women's Farming Groups

Abstract

This research aims to obtain biodiesel by transesterification of coconut oil with MgO/SiO2 as a catalyst, with the objective to examine the effect of MgO loads on the performance of the catalysts expressed in terms of oil conversion. The MgO/SiO2 composites with different mass ratios of 1:1, 1:2, 1:3, 1:5, and 1:10 were synthesized from Mg(NO3)·6H2O and SiO2 extracted from rice husk silica using sol-gel method and followed by calcination at 800 °C for 6 h. The produced catalysts were then tested in the transesterification of coconut oil to investigate the effect of catalyst composition, oil to methanol ratios, and reaction times. The experiments were carried out using a fixed catalyst load of 10% oil (w/v) and at 70 °C. The catalyst with the highest performance was then characterized by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to confirm the formation of crystalline MgO/SiO2. The highest conversion of the transesterification product was analyzed using gas chromatography-mass spectrometry (GC-MS) technique to confirm the biodiesel production. The XRD diffractogram of the synthesized sample is characterized by the presence of sharp peaks confirming the existence of the sample as crystalline material attributed to the pyroxene-ideal (MgO3Si) phase. The existence of the sample as crystalline material is also supported by the absence of a broad diffraction peak attributed to amorphous rice husk silica, and SEM image of the sample which is characterized by the visible existence of crystalline structure in the forms of platelet prismatic, and tetrahedral shaped structures. The results demonstrated that the highest conversion (98%) was achieved with the use of MgO/SiO2 (1:5) as a catalyst, a ratio of oil to methanol of 1:6, and a reaction time of 4 h. The formation of methyl esters was confirmed by the results of GC-MS analysis.

Abstract

In this research, palm oil mill effluent (POME), was pyrolized using a modified Lampung natural zeolite (LNZ) catalyst. Modification was conducted by reducing the Si/Al molar ratio to 1 by mixing certain mass of food grade aluminum food dissolved in 1.0 M NaOH solution and certain mass of LNZ. The mixture was homogenized using a magnetic stirrer, left at room temperature for 12 hours, and finally subjected to hydrothermal crystallization at 100 ºC for 72 hours. The solid sample produced was dried and calcined at 600 °C for 6 hours then characterized using X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) techniques to evaluate the formation of zeolite-A. The BCO produced from the pyrolysis experiment was analyzed using gas chromatography-mass spectrometry (GC-MS), revealing the presence of hydrocarbon as the main components (70%), suggesting the promising potential of the catalyst for further investigation.
