Abstract

This study aims to determine the level of readiness of the Batik Tulis Small and Medium Industry in Sidoarjo district in implementing One Village One Product (OVOP) by mapping the assessment criteria based on the Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) matrices, as a first step in conducting analysis using the Strengths, Weakness, Opportunities, and Threats (SWOT) method. OVOP is a way to develop the potential of an area that was pioneered by Dr. Morihiko Hiramatsu has succeeded in alleviating poverty in Japan's Oita Prefecture through the Japan External Trade Organization (JETRO) by motivating the economies of several developing countries albeit under different names. Base on the identification of the performance of 30 small and medium industries (SMI) spread across 5 batik centers, it can be seen that the level of readiness is 81%. The results of the 82 evaluation criteria means that the product quality is good and has been classified as 4 star even though the marketing area is only in the country. So that the value still needs to be increased on several indicators (A). Aspects of Production, Product and Community Development, (B). Marketing Aspects and Product History, (C). Aspects of Product Type, Quality, and Market Opportunities. Of the 25 indicators of OVOP product assessment for the batik category, when mapped in the IFE matrix, 8 are seen as strengths and 4 of weakness, while in the EFE matrix, 7 of opportunity and 6 of threats are seen.

Abstract

Land cover heterogeneity can affect the structure of biodiversity in the supplied niche, so it is necessary to know the taxa community. This study aimed to understand the effect of land cover variation on the diversity and community structure of soil arthropods. The types of habitats used include urban areas, agroforestry, gardens, and natural forests which are determined in the Malang Region, East Java, Indonesia. Hand sorting and hay bait traps were applied in this study to obtain a variety of arthropod soils and the Berlese-Tullgren funnel was used to extract them. As a result, there are 25 families from 15 orders collected based on their ecological roles. The abundance of Philoscidae in sites S1 and S2 (urban green space), Talitridae in site S6 (agroforestry), and Isotomidae in sites S3, S4, and S5 (highland mixed forest) was highest and dominant. Site S7 has the highest diversity (H' = 2.56; 1-D = 0.90; J' = 0.76) even though its family richness is lower. The site S3 counter-site had relatively high taxa richness (TR = 13), but low diversity (H' = 1.02; 1-D = 0.39; J' = 0.16). Based on clustering analysis and NMDS ordination, 3 classifications of habitat types were obtained, namely I (S6 & S7), II (S3, S4 & S5), and III (S1 & S2). Mixed forest habitats contain a more complex diversity of soil arthropods, which can serve as a model for improving the fertility of disturbed ecosystems.

Abstract

One of the efforts to manage the risk of ground movement is to identify landslide-prone area characteristics. This study aimed to investigate the geophysical, geotechnical, and vegetation characteristics of landslide and non-landslide areas. This study adopted the resistivity geoelectric method to identify the type and structure of subsurface materials in landslide and non-landslide regions in Pujon and Ngantang, Malang Regency. Measurements in this study were done in four locations. Each geoelectric measurement path at each location was determined to be 100 m long. The electrodes were spaced apart by 10 m for measurements between the current electrode and the potential electrode. The dipole-dipole configuration of the geoelectric survey trajectory is determined based on the former landslide event to predict underground material. In addition, an investigation of geological, geotechnical, and vegetation characteristics was carried out. The results showed that the geophysical, soil, and vegetation characteristics of the landslide and non-landslide slopes were similar. The geophysical characteristics of the soil in all study locations indicate the presence of a slipping surface, which makes the land prone to landslides. The slipping plane was formed due to differences in the types of rocks between the surface and deep layers. The existence of vegetation has an important role in landslide management. Non-landslide areas tended to have denser tree vegetation and a higher number of shrub species.

Abstract

East Java was one of the top five waste Indonesian producers in 2020, and the waste bank is a promising strategy for managing domestic waste better. This study aims to evaluate the performance and sustainability of waste banks in East Java. The research was conducted by observing 40 Surabaya, Malang, and Gresik waste banks. The interview involved managers and 10% of waste bank customers. The bank’s performance and sustainability were determined by some indices: effectiveness, elasticity, zero-waste index (ZWI), and diversion rate. Results showed that waste banks varied in the establishment age (6 to 10 years) and performance (moderate to high). The highest proportion of waste managed by waste banks was plastic and paper. However, some of them also managed degradable waste. The Gresik and Malang District waste banks were established younger and performed better than the Surabaya City ones.  All waste banks reduced waste slightly, as shown by the ZWI index (0.20 to 0.40) and diversion rate (21 to 40%) in reducing waste volume disposal to landfills. Its sustainability constraints were facilities, prices, partners, community or government support, and the COVID-19 pandemic. Waste banks provided some benefits, including increasing sorted waste, environmental sanitation, income, and culture changes. Keywords: Covid-19, East Java, performance, sustainability, waste banks

Abstract

Brantas River is the largest river in East Java, flowing from the city of Batu upstream until downstream in Surabaya and Sidoarjo. This river plays a crucial role as a vital natural resource that supports the various needs of the surrounding communities. This study serves as a preliminary investigation with the primary aim of assessing the water quality in three different zones of the Brantas River: the upper, middle, and downstream sites. Additionally, this research includes a review to identify the organisms exposed to water pollution in the Brantas River. The study was conducted from November 2020 to April 2023, utilizing an exploratory observational method at 19 observation stations. The data obtained was subsequently analyzed using a descriptive approach. Various parameters were observed, including pH (a measure of acidity or alkalinity), hardness (the concentration of calcium and magnesium ions), alkalinity (the capacity of water to neutralize acids), nitrate, nitrite, fluoride, and heavy metals such as lead (Pb), copper (Cu), and iron (Fe). The research findings indicate that in several upstream areas of the Brantas River, there were elevated hardness, nitrate, lead (Pb), and iron (Fe) that exceeded the established water quality standards. In the middle section of the river, water quality was generally satisfactory, although a few locations exhibited slightly elevated levels of lead (Pb). Meanwhile, all locations downstream of the Brantas River demonstrated water quality that exceeded the prescribed standards. After a literature review, it was discovered that various biota in the Brantas River have been exposed to pollutants, including fish species and plants like Ipomea aquatica and Eichhornia crassipes. Therefore, it is necessary and urgent to improve water management and monitoring plants and biota in the Brantas River to preserve organisms in aquatic and terrestrial ecosystems.

Abstract

Organic waste easily emits horrible smells if not quickly processed. One way to process organic waste is by using an aerobic composter on a household scale. Organic waste processing has been socialized through the Department of Hygiene and Parks of Surabaya since 2002. This study aims to measure Jambangan village residents' participation rate in processing organic waste with composters. The method of this study is a survey of the Jambangan village residents that have installed the composters and have the space to place the composters. The data will then be analyzed with descriptive statistics. The data shows that Jambangan village residents' participation rate in processing organic waste with aerobic composters is very low. This is caused by a lack of knowledge and awareness among the public, combined with limited space availability. These factors contribute to the low participation rate of the community in organic waste processing. Keywords: composter,  jambangan village, participation, organic waste

Abstract

The Leachate Treatment Plant (LTP) at Supit Urang Landfill produces a by-product of dewatered sludge that has not been utilized optimally and according to its potential. Sludge is a highly organic material that agriculture can reuse as a fertilizer or soil conditioning agent. However, its potential heavy metals possess environmental risks. Currently, sludge from the dewatering process is disposed of in landfills. Sludge left open without further handling will potentially be a source of environmental pollution that will cause unpleasant odors. This study aims to identify how to utilize sludge as raw material for compost mixtures. The approach applied in this research was quantitative with an experimental design. Sludge was mixed with ready-made compost and EM4 solution. Composting is carried out with three different ratios of sludge and compost, which consist of (w/w) 1:1 (M1), 1:2 (M2), and 1:3 (M3). The addition of EM4 solution (10% of the mixture weight) was used to enhance the efficiency of the composting process. The result revealed that after 21 days, the quality of co-composting sludge and ready-made compost met the requirements of SNI 19-7030-2004. The best results were obtained in mixture M3 (C-Org = 17.92%, Ntotal = 1.71%, Ptotal = 0.80%, Ktotal = 1.33%, C/N-ratio = 10.38, Cd = 2.47 mg.kg-1, Hg = 0.0 mg.kg-1). These findings suggest that sludge has the potential to be used as raw material for compost mixtures.
