Abstract

Waste management in West Nusa Tenggara Provincial Government focuses on two main things, namely the reduction and handling and providing of TPA which is still operated with an open dumping system. Application of an open system in TPA will cause many problems, including air pollution by methane gas and the greenhouse effect. This study aims to determine the potential methane gas content of the Kebon Kongok landfill as an alternative energy source by modelling using LandGEM. The data in this study consisted of the year of the TPA operation plan and the annual data on the waste generation of TPA. The results showed that the potential content of methane gas was 12,999,633.62 m3/year, or equivalent to 14,520.88 MWh/year, in the form of gas as much as 9,966.38 Megagrams of LPG/ year. Therefore, the Kebon Kongok TPA has the potential to be used as a power plant fuelled by methane gas and facilitates electricity connections for the surrounding community because when compared to other existing renewable energy plants in the Lombok Electricity System, the capacity of 1.66 Megawatts was already  equivalent to the power generation  capacity which are already operating commercially.

Abstract

This article is a part of studies to investigate the potential of natural products from Lombok Island for antidiabetic agents. This study was directed to learn the metabolite variations of peanut hulls collected from three different locations in Lombok Island. The hull samples were extracted in methanol, followed by partition process into three fractions using three solvents with varied polarities (dichloromethane, hexane and acetone). The fractions were then separated and identified for their chemical composition by using GC-MS instrument. Metabolite variations of three extracts showed that the antidiabetic compounds stigmast-5-en-3-ol and oleic acid were found in all three locations with different percentages of abundance. Another antidiabetic compound, linoleic acid, was only identified in peanut hulls from the village of Pringga Jurang (PJ). Besides the antidiabetic compounds, there were other major compounds with known biological activities discussed to find other uses of the hulls.

Abstract

The purpose of the service is to design a wastewater treatment installation system that will be used for laboratory waste in the Mataram STTL environment. The problem of liquid waste from the laboratory in the STTL Mataram environment from the existing conditions does not yet have a Waste Water Management Installation (IPAL). Liquid waste from the laboratory is still in the same network as domestic liquid waste. So it is necessary to make a special WWTP for the liquid waste of the Mataram STTL Environmental Laboratory. Before making the WWTP first, knowing the content of the wastewater, this aims to find out what types of waste are most commonly found in laboratory liquid waste, so that laboratory wastewater testing is carried out using several parameters such as BOD, COD, TSS, pH and Colifrom. In testing the wastewater of the Mataram STTL Laboratory, Colifrom bacteria are bacteria that exceed the Threshold Value and wastewater treatment plants can be made during the service process. ABSTRAKTujuan pengabdian untuk merancang sistem instalasi pengolahan air limbah yang akan digunakan terhadap limbah Laboratorium di lingkungan STTL Mataram. Permasalahan limbah cair dari Laboratorium di lingkungan STTL Mataram dari kondisi yang ada belum mempunyai Instalasi Pengelolaan Air Limbah (IPAL). Limbah cair dari Laboratorium masih dalam satu jaringan dengan limbah cair domestik. Sehingga perlu di buatkan IPAL khusus untuk limbah cair Laboratorium Lingkungan STTL Mataram. Sebelum membuat IPAL terlebih dahulu mengetahui kandungan dari air limbah tersebut hal ini bertujuan untuk mengetahui jenis limbah apa saja yang paling banyak terdapat pada limbah cair laboratorium sehingga dilakukan pengujian air limbah Laboratorium dengan menggunakan beberapa parameter seperti BOD, COD, TSS, pH dan Colifrom. Dalam pengujian air limbah Laboratorium STTL Mataram, bakteri Colifrom merupakan bakteri yang melebihi Nilai Ambang Batas dan instalasi pengolaahan air limbah dapat dibuat selama proses pengabdian berlangsung.

Abstract

This researh aims to detect the presence of histamine by forming complex compounds of 5-fluorouracil, Mn (II) metal ions and alizarin red S reagents. This type of research is a laboratory experiment. This research was conducted at the Ikip Chemistry Laboratory in 2019. The results showed that the Test Kit that was made could be used to detect the presence of histamine determining the existence of histamine qualitatively viewable color formed based on complex compounds of  Mn(II)-His-5FU-ARS seen from the shift in wavelength of maximum generated.. The making of the histamine test kit is made by varying the concentration of 10-100 ppm at 10 ppm   intervals under optimum conditions and can be used to make a color comparator solution. Then  the method validity test is done by making a standard histamine curve that gives a regression equation  y = 0.001x + 0.3364 with a correlation coefficient (r2) = 0.9972. Based on the validity test method, the accuracy value is in the range of  95.0-106% and the results of the test kit on tuna samples indicate that the histamine test kit made has a good accuracy value because the average recovery value is 96%.

Abstract

Cigarette butt waste can be used for biopesticides for environmentally friendly agricultural activities. Biopesticides cigarette can be produced by conducting a maceration extraction test using polar, non-polar, and semi-polar compounds and conducting a Mass Spectrometer Chromatography (GC-MS) test. This study aims to determine the effectiveness of bio-pesticide based on tobacco extract from cigarette butt waste for maize (Zea mays L.)". The highest yield value was the ethanol sample of 1.208%, compared to the N-hexane sample of 0.25% and the DCM sample of 0.6%. For the comparison of solvents used were 500 ml of ethanol, 250 ml of N-hexane, and 250 ml for DCM as well. After conducting the GC-MS test, the compounds obtained are alkaloid compounds, phenolic compounds, sesquiterpenoid compounds, and terpenoid compounds, each of which has benefits as a pest control or deterrent to plants. For the effectiveness test results on Corn (Zea mays L.), there was no intensity of pest attack on the ethanol sample, N-hexane sample, and DCM sample. In contrast, there was a pest attack intensity of 0.3% for the control sample. Therefore, the Biopesticides studied are similar to synthetic pesticides because they can eradicate pests and make growth effective faster.

Abstract

Kabupaten Lombok Barat dalam mengurus sendiri rumah tangganya termasuk melakukan pengendalian dan pengelolaan sampah telah membuat suatu Peraturan Perundang-undangan yaitu Peraturan Bupati Lombok Barat Nomor 6a Tahun 2015 tentang Pengelolaan persampahan/kebersihan. Zero waste merupakan salah satu upaya untuk meminimalisir sampah mulai dari produksi sampah berakhirnya suatu produksi.. Prinsip yang digunakan dalam konsep zero waste ini tidak hanya 3R (Reduce, Reuse, Recycle), namun juga 4R hingga 5R yaitu Reduce, Ruse, Recycle, Replace, dan Replant. Desa Suka Makmur memiliki 12 Dusun, di antaranya adalah Dusun Egok Selatan dan Dusun Egok Tengah. Berdasarkan observasi tim dengan cara menemui Kepala Desa Suka Makmur dan Kepala Dususn Egok Tegah dan Kepala Dusun Egok Selatan diperoleh suatu masalah yaitu terkait dengan sampah rumah tangga. Berbagai macam jenis sampah rumah tangga di antaranya adalah sampah pelastik, sampah sisa makanan, sampah sayuran, kulit buah, dedaunan dsbPengabdian Kepada Masyarakat ini akan melakukan sosialisasi atau Pelatihan Pengelolan Sampah Rumah Tangga dengan Konsep Zero Waste di Dusun Egok Selatan dan Egok Tengah Desa Suka Makmur Kec. Gerung Lombok Barat Tahun 2022.
