Abstract

Cleaner Production (CP) practices comprised environmental strategy perpetually applied in the production, processes, and services to bolster efficiency, safety, and environmental friendliness. Some factors are to be considered to achieve a cleaner production strategy: stakeholders establishment, surveys, utilization, and impact, as well as how the top management devote their practices towards cleaner production. Combining with the mindset of sustainable stocks and resources, this exercise of cleaner production provides advantages of minimum toxic wastes and residues. In this study, we prioritize this practice to be applied in the aluminum industry, of which cleaner production action has not yet been employed. Small and medium businesses now no longer have enough monetary assets to put money into cleaner production practices because they require high-cost investment. This study aimed to determine the factors that have an impact on the application of cleaner production. The method used is regression analysis. The regression analysis results showed that three variables were tested to be significant and had a Root Mean Square Error (RMSE) value of 3.05 which means good. Three variables that affected the implementation of cleaner production include measurement of fuel usage, efforts to improve production process efficiency, and waste reuse by product. From the calculation results, the coefficient of determination (R2) was 0.550 (the influence was quite strong). The results of this study can be used as a recommendation for the government to increase the implementation cleaner production in Jombang Regency.

Giri Kedaton Site was a kingdom founded by SunanGiri and served as the Core City II Gresik in 1487 AD. Currently Giri Kedaton transforms to become cultural tourism object in religious or pilgrimage tourism sector. In 2002-2005, the local government conducted preservation and conservation activities at the Giri Kedaton site. The purpose of this study was to identify the characteristics as well asto measure the vitality of Giri Kedaton site, and determine the variables that may affect the vitality of the sites. The identification of the characteristics of the GiriKedaton site is explained by researcher by using qualitative descriptive analysis, while the frequency distribution analysis was employed to assess the vitality, and the variable effect was analyzed by multivariate linear regression. Based on its mode value on an analysis of a frequency distribution obtained value vitality giri kedaton site is low, from the results of linear regression analysis multivariate obtained the best method that is a enter methode, where model is as follows : Y = - 2.884 + 0,075 X1+ 0,039 X2 + 0,055 X3 + 0,119 X4 + 0,174 X5 + 0,115 X6 + 0,108 X7 + 0,110 X8 + 0,071 X9 + 0,158 X10 + 0,005 X11 + 0,92 X12 + 0,159 X13 + 0,265 X14 + 0,153 X15. Based on the result analysis of the regression (t-test) variable influence significantly is government's support (0.002), sidewalks (0.005) and housings (0.047). The conclusion of this study showed that the Giri Kedaton site has supporting function as religious tourism but there is still lacks of adequate infrastructures and facilities including parking areas and economic facilities. In addition to the length of visit (1-3 hours) and the frequency of visits (first visit) have a low value which indicates that the Giri Kedaton site has limited tourism attraction; in other words, it has not been recognized by most visitors. For the vitality of Giri Kedaton site is low as the travelers rated the infrastructure aspects not sufficient to support the site as a religious tourism attraction. For the multivariate linear regression model used was the enter model and only three independent variables who is influential significantly to the site that is government's support (X14), sidewalks (X5), conditions of housing facilities (X10).

Abstract

In daily life, papayas are often discarded and become waste due to overripeness or not being consumed in time. Based on their composition, papayas have strong potential as a base for non-food products due to their wide-ranging benefits. Papain enzymes, vitamins A, C, and E, as well as flavonoids and saponins found in papaya, have been shown to possess antioxidant and antibacterial properties, and can act as natural exfoliating agents for the skin. These characteristics make papaya a promising natural ingredient for developing body care products such as bar soap. Accordingly, a Pengabdian kepada Masyarakat activity was carried out to introduce the use of papaya as a raw material for natural bar soap. This initiative aimed not only to address the issue of papaya waste but also to educate the community on the economic potential of household-level food processing. The activity was conducted through an educational and participatory approach, involving socialization and hands-on training. As a result, the program received positive responses and high enthusiasm from participants, and helped introduce new skills with potential for independent application and added household economic value.

Abstract

TPS 3R is a community-based waste management approach aimed at reducing waste generation through reduce, reuse, and recycle activities. However, the operational sustainability of TPS 3R still faces several challenges,including  waste processing effectiveness, and community participation. This study aims to analyze the community’s Willingness to Pay (WTP) for waste management fees and to formulate priority recommendations for improving the performance of TPS 3R Banjar Sugihan using the Quality Function Deployment (QFD) method. The research was conducted in Banjar Sugihan Village, Tandes District, Surabaya City, involving 563 household respondents. WTP analysis was carried out using the bidding game method, while QFD analysis was conducted through the preparation of the House of Quality (HoQ). The results showed that the community’s WTP ranged from IDR 16,000 to IDR 19,000 per month. If applied to all 3,758 households in Banjar Sugihan Village, the potential retribution revenue is estimated to reach IDR 60,128,000–IDR 71,402,000 per month. The QFD analysis indicated that the priority strategies for improving TPS 3R performance include enhancing infrastructure facilities, optimizing waste sorting and processing, increasing waste processing capacity, strengthening human resource capacity, and implementing a WTP-based retribution system. Therefore, the implementation of a WTP-based retribution system and priority strategies derived from QFD analysis are expected to support the sustainability of waste management at TPS 3R Banjar Sugihan.

Abstract

Ungkapan “a city without old buildings is just like a man without memory” sangat relevan untuk mengungkapkan betapa pentingnya makna sejarah pada bangunan kuno di suatu tempat, terlebih bangunan kuno itu selain mempunyai sejarah, juga mempunyai locus, makna ataupun nilai yang tinggi. Akan tetapi, perkembangan kota secara ekonomi dan dinamika sosial yang semakin modern akan menenggelamkan makna sejarah sebuah kota jika tidak ada momentum untuk menjaga dan melestarikannya yang akan mengakibatkan sebuah proses pelupaan terhadap sejarah. Tujuan penelitian ini adalah mengidentifikasi kawasan sejarah dan bangunan kuno, mengidentifikasi memori-memori masyarakat gacor5000 terhadap bangunan kuno dan mengetahui tipologi memori kolektif yang terbentuk dari keberadaan bangunan kuno sehingga dapat dimaknai proses pembentukan sejarah di Kota Bima di masa kesultanan Bima. Metode analisis yang digunakan adalah deskriptif kualitatif. Hasil yang ditemukan adalah bahwa terbentuknya tiga memori kolektif Kota Bima dalam bangunan kuno yaitu memasarkan memori, penaklukan memori dan memisahkan memori. Kata Kunci: Bangunan Kuno, Kawasan Sejarah, Tipologi Memori Kolektif

Abstract

Household waste, including residues from daily activities, can negatively impact the environment if not properly managed. This study focuses on household waste management in RT 03 RW 01 Desa Ngadilangkung, Kecamatan Kepanjen, Kabupaten Malang, with the aim of raising awareness and knowledge among the community about the benefits of rice washing water. The methods used include primary surveys through observations and interviews with village officials, the head of RW, the head of RT, and the community. The survey results indicate that most households have not optimally utilized rice washing water, with only 6% of households engaging in processing and 94% not recycling. Socialization efforts were conducted to educate the community on the production of liquid organic fertilizer (POC) from rice washing water, which is expected to improve waste management and more effectively utilize household waste. The outreach results indicate a significant potential for the application of POC in the village, although there remains a need for further education on waste management.

Abstract

Increasing amounts of household waste due to population growth may lead to problems if it is not accompanied by an efficient waste management system. Along with efficiency, waste management should include waste reduction which can be implemented through Reduce, Reuse, and Recycle (3R concept). 3R can be conducted in a facility called TPS3R. Bandung, one of the big cities in Indonesia has implemented 3R in TPS3R. There are a growing number of TPS3Rs being built, but most of them lack management capacity. Out of seven TPS3Rs in Bandung City, TPS3R Saling Asih has the lowest capacity to treat the waste which is only 28.89% of the total waste production in the serviced area. Therefore, this research aims to evaluate the Level of Service (LoS) TPS3R Saling Asih using indicators scored based on some criteria. The score is weighted according to the importance and the urgency. The indicators are grouped into five aspects i.e., related regulation products, technical-technological, management institutional, financial operational, and participation. The evaluation results gained a relative value of 14.25 indicating less function. The recommendations for the results were preparation for performance improvement focusing on the indicators with low values.

Abstract

The discovery of illegal dumping activities in Bangkalan sub-district shows that there is inequality in services provided by the waste collection system. This needs to be reviewed through calculations from an analysis of the effectiveness of the waste collection system in order to assess the performance of waste collection at temporary waste shelter sites in Bangkalan District and improve environmental livability. Therefore, this research aims to evaluate the effectiveness of the waste collection system in Bangkalan Regency through the performance of each temporary waste shelter. The analysis used is the effectiveness of the waste collection system by dividing the output value by the input. The results of the effectiveness analysis will be compared with the Jakstranas document, which states that a temporary waste shelter can be said to be effective if it has an effectiveness value of 100%. Based on calculations, three temporary waste shelter were found in Bangkalan District whose value was below 100%, namely Pangeranan 3R Waste Management which has a percentage value of 15%, recycling house which has a percentage value of 26%, and Martajasah 3R Waste Management, which has a percentage value of 54%. This can be caused by an uneven waste collection system, limited waste infrastructure, limited waste officers, and a lack of public awareness. Apart from that, the existence of illegal dumpings around the temporary waste shelter area is also evidence that the temporary waste shelter is not running effectively.

Abstract

AbstrakBerbagai permasalahan transportasi yang sering dialami dengan kepadatan lalu lintas yang tinggi salah satunya adalah kecelakaan lalu lintas. Kecelakaan lalu lintas di Kota Surabaya pada tahun 2017 tercatat sebanyak 1.338 kejadian kecelakaan. Jumlah kejadian kecelakaan ini didominasi oleh kendaraan pribadi seperti sepeda motor dan mobil. Penelitian ini bertujuan membuat model peluang kecelakaan mobil di Kota Surabaya yang didasarkan pada data karakteristik jalan dan karakteristik pengendara untuk mengetahui tindakan yang tepat dalam menurunkan angka kecelakaan mobil. Metode yang digunakan dalam penelitian ini adalah analisis generalized linear model (GLM) untuk melihat model peluang kecelakaan mobil berdasarkan karakteristik jalan dan regresi logistik biner untuk melihat model peluang kecelakaan mobil berdasarkan karakteristik pengendara mobil. Penelitian ini difokuskan pada six ruas jalan yang memiliki tingkat kecelakaan tertinggi dan sedang, serta diwakilkan dengan 348 responden pengendara mobil. Dari hasil analisis GLM didapatkan model peluang kecelakaan McA = ??4,5 − 0,707 Lebar badan jalan yang menunjukkan bahwa hanya lebar badan jalan yang mempengaruhi peluang kecelakaan mobil. Hal ini dapat diintepretasikan bahwa jika lebar badan jalan memiliki peningkatan 10% dari lebar badan jalan sebelumnya, maka model pendekatan dengan GLM memprediksi akan terjadi peningkatan jumlah kecelakaan mobil sebanyak 84 korban. Dari hasil analisis regresi logistik biner didapatkan model peluang kecelakaan di mana perilaku pengendara yang mempengaruhi peluang kecelakaan mobil adalah membawa surat berkendara seperti SIM dan STNK (X3.6), mematuhi lampu lalu lintas (X3.10), memberi tanda berbelok/darurat (X3.11), menggunakan sabuk pengaman (X3.12), dan mengantuk saat mengendarai (X3.13).Kata kunci: Model kecelakaan, pengendara mobil, generalized-linear-model, Kota Surabaya.AbstractSimulation Study of Car Accident Model to Improve Traffic Safety in the Urban Area: Various transportation problems that are often experienced with high traffic density, one of which is a traffic accident. The number of accidents is dominated by private vehicles such as motorbikes and cars. This study aimed to make a car accident model in Surabaya Ciy based on the road and the driver characteristics to find out the right actions in reducing the number of car accidents. The study used the analysis of generalized linear model (GLM) and binary logistic regression. It focused on six road segments that have the highest and moderate accident rates, and it was represented by 348 respondents of car drivers. The results of the GLM analysis obtained a probability model of McA = ????,?? − ??,??? ?? ???????? ????? ???? which shows only the width of the road body that affects the chances of a car accident. It can be interpreted that if the road width has increased by 10% from the previous road width, the GLM approach model predicts an increase in the number of car accidents by 84 victims. Furthermore, the driver’s behavior that affects the chances of a car accident include carrying a driver license and vehicle registration (X3.6), obeying a traffic light (X3.10), giving a turning/emergency sign (X3.11), using a seat belt (X3.12), and being drowsy when driving (X3.13).Keywords: Accident model, car driver, generalized-linear-model, Surabaya City.
