Memberdayakan Rumah Tangga untuk Pengelolaan Sampah Berkelanjutan: Studi Kesadaran Masyarakat di Kota Semarang

Environmental sustainability issues, particularly related to the increasing amount of waste, have become a major concern in Semarang, the capital of Central Java Province. The generation of waste is influenced by low public awareness, economic growth, and the presence of urban centers, industries, and educational institutions. Semarang has recorded a high economic growth rate, even surpassing the national average, contributing to the rise in waste. Various initiatives have been undertaken by the local government, such as establishing waste banks and implementing paid plastic bags, yet the waste problem remains difficult to solve without household awareness, as they are the largest contributors. This study employs a mixed-methods approach in six urban villages, with 50 respondents from each. The findings indicate that public awareness regarding waste sorting from households is still low, despite its crucial role in reducing waste volume and supporting environmental sustainability. Women, due to their domestic roles, play a key part in waste sorting, but the active participation of all community members is essential for the success of sustainable waste management programs.Keywords : environmental sustainability, waste management, waste sorting, household awareness, Semarang

The Assessment of Peak Discharge Increment Due to Land Use Change in the Serang Welahan Drainage 1 (SWD 1) River, Central Java Province, Semarang

SWD1 River is located in one of those flood-prone areas in Central Java that generates flood hazards causing high risk to the surrounding rice fields and communities. However, a comprehensive study of flood hazards in SWD1 River has never been conducted. Nowadays, previous comprehensive flood studies in Indonesia only available for several very developed areas, such as the Jakarta Flood [1] – [5], Bandung Flood and Solo Flood , or new iconic area for mangrove conservation such as Langsa City . Most previous studies conclude that flood hazards in Indonesia are commonly generated by rain runoff, tides, and dam break flows, or a combination of these generators . Existing conditions show that SWD 1 is unable to accommodate runoff from the Wulan River, causing flooding. Based on rainfall data from BMKG, the maximum rainfall per month for a year reaches 323 mm. This study is an effort to analyze the impact of land use change.The research method used analysis of the influence of changes in CN (Curve Number) due to changes in land use on flood discharge as shown through changes in the Soil Conservation Service (SCS-CN) hydrograph on discharge and runoff volume. The selection of the SCS-CN method is due to its widespread adoption in various regions, its extensive use in numerous analytical studies, and its suitability for the characteristics of the watershed under review.The analysis results show that there has been a change in flood discharge from 2019 and 2022 with values of 366.920 and 371.154 m3/second. The discharge values did not change significantly because the CN values were as follows, 83.25 and 83.36. Through analysis, it can be seen that an increase in discharge of 1.14% from 2011 to 2022.The several alternatives are needed to reduce flooding, such as watershed conservation upstream, minimizing land use changes and building flood mitigation infrastructure downstream.

Understanding the determinants of the empowered earthworm farmers’ behavior

Earthworm (Lumbricus rubellus) farming offers a unique solution for poverty alleviation in rural Indonesia by transforming agricultural waste into economic opportunities while supporting sustainable farming practices. Empowering these farmers is crucial for enhancing their cultivation techniques and economic outcomes. This study examines the key factors that influence the behavior of empowered earthworm farmers, using the Theory of Planned Behavior (TPB) as its framework. Conducted in Temanggung Regency, Central Java Province, Indonesia, in 2023, the study involved 201 respondents selected through a snowball sampling method. Information was gathered via a survey and then examined using PLS-SEM. The findings indicate that empowerment programs significantly influence farmers’ attitudes, social norms, and perceived behavioral control, which drive their intention to become empowered. Empowered intentions and perceived behavioral control strongly predict farmers’ empowered behaviors, which, in turn, enhance their economic well-being. Notably, the study also found that farmers' personality traits do not moderate the relationship between intention and behavior, suggesting that empowerment programs are broadly effective across different farmer profiles. This study underscores the importance of empowerment initiatives in promoting sustainable farming practices, improving farmers' livelihoods, notably the livelihood of farmers, as the empowerment program is based on dynamic open innovation.

A preliminary report of integrating sheep farming in combination with adopting biogas technology in organic rice farming systems in upland areas in Indonesia

The research was conducted in upland areas in Grabag Subdistrict Magelang Regency, Central Java Province (UPL1) and Kertasari Subdistrict, Tasikmalaya Regency, West Java Province (UPL2), Indonesia. At each upland area, a demo plot with a 17 m3 digester has been established, and 120 sheep were introduced. A combination of sheep and beef cattle manure was used as a biogas substrate. The soil sample of one and three-year conversion of ORF was collected, and macro and micro minerals were analyzed. The biogas quality was analyzed, including dry matter (DM), nitrogen (N), carbon (C) and nitrogen-ammonia (N-NH3). The greenhouse (GHG) emissions, including methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O), were measured. The results indicated that C-organic content at three-year conversions of ORF in UPL1 was much lower (P<0.05) than the one-year conversion. The average CH4, CO2, and N2O contents in UPL1 were 661, 477.3, and 0.16 mg/m2/day, respectively. The average CH4, CO2, and N2O contents in UPL2 were 3328, 3038 and 2.42 mg/m2/day, respectively. In UPL1, the proportion of CH4 was 52.5 %, CO2 was 47.4 %, and N2O was 0.01 % while the proportion of CH4 was 57.9 %, CO2 was 42.0 %, and N2O was 0.01 % in UPL2. To conclude, integrating sheep farming in combination with adopting biogas technology in the ORF system improves manure management and provides organic fertilizer, which subsequently reduces the use of artificial fertilizer and avoids GHG emissions.v

Land suitability evaluation in the Northern Limestone Mountains of Tuban Regency, East Java for torch ginger (Etlingera elatior Smith) cultivation

Torch ginger (Etlingera elatior) is a herbaceous plant from Southeast Asia, traditionally used as herbal medicine by local people due to its antibacterial, antiviral, anti-inflammatory, anti-allergic, antioxidant, and anti-cancer properties. Despite its various benefits, this plant has struggled to enter the market because it has not been cultivated on a large scale. Therefore, the opportunity for commercial cultivation of this plant remains wide open. Tuban Regency is a potential agricultural district in Java, strategically positioned on the main road between Central Java Province and East Java Province. Unfortunately, little research has been conducted on land suitability evaluation in Tuban Regency’s agricultural areas. This research aimed to evaluate land suitability for torch ginger cultivation in Tuban Regency. Based on the studies conducted, agricultural land in Tuban Regency is quite fertile, but adequate irrigation is necessary to help the plants survive during the dry season. Torch ginger naturally grows in densely vegetated areas with sufficient water availability. Therefore, cultivating torch ginger in Tuban requires several special treatments, such as maintaining water availability, providing shade and mulch to regulate temperature and humidity, applying phosphorus and organic fertilizers to address phosphorus fixation in limestone soil, and using growth regulators like paclobutrazol to overcome flowering inhibition. From the various literature that has been studied, it was found that the land in the Northern Limestone Mountains of Tuban Regency, is quite fertile and suitable for agricultural land.

Expert perspectives on disaster risk reduction strategies in the tourist area of Borobudur-Yogyakarta-Prambanan in Indonesia

Tourism plays a crucial role in the economic growth of many countries. However, tourist destinations located in disaster-prone areas face increased vulnerability in the event of natural disasters. It is essential for these areas to have specific interventions, plans, and policies that focus on reducing disaster risk, while ensuring the safety of residents and tourists. This study proposes strategies for minimizing disaster risk using Indonesia's Borobudur-Yogyakarta-Prambanan (BYP) region as a case study. The study used an Analytical Hierarchial Process in a Strengths Weaknesses Opportunities and Threats (SWOT-AHP) analysis to prioritize factors through pairwise comparisons and develop strategic alternatives based on expert perspectives. Primary data were collected through aSWOT-AHP questionnaire that was provided to 22 experts in tourism and disaster management in Central Java and Yogyakarta Special Provinces. Secondary data were obtained from government documents, specifically the Disaster Risk Reduction Plan for the BYP regions (2023–2027). The results indicate that “implementing land-use policies to promote tourism development while considering disasters” is the most important strategy, based on expert judgment. The BYP tourist destinations provided a case study to identify strategies to reduce disaster risk in tourism areas.
