Abstract

Barangay Malinta has a regular garbage waste collection schedule. Biodegradable wastes are collected on Mondays, Wednesdays, and Fridays while non-biodegradable wastes are collected on Saturdays. The barangay is compliant to the RA 9001 (Solid Waste Management) however, they do not have a Material Recovery Facility (MRF). The absence of MRF is due to geographical location of the barangay which prohibits the establishment of the MRF facility due to its proximity to Laguna bay. The study aims to determine the perception of the respondents regarding the Clean-up Drive activities at the Saran River and to integrate it with the recommendations to aid in the improvement of the cleaning efforts for the said river, particularly at Barangay Malinta, Los Baños, Laguna, Philippines. Random sampling was used to identify residents to be included in the survey. The data were analyzed using percentage and mean. The results showed that the level of awareness among respondents residing Saran river is high. In terms of attitude, most of them strongly agreed that there will be a clean-up in the river and penalized those who will throw their waste in the river, most of the respondents are satisfied with the on-going river clean-up and optimistic that the river can still be cleaned and revived, and most of the respondents are willing to contribute amount and will be paid in the barangay as funding to river clean-up.

Abstract

Secara geografis, Kecamatan Utan terletak di wilayah pesisir Kabupaten Sumbawa, dengan potensi perikanan dan kelautan yang melimpah. Salah satu potensi yang ada di Kecamatan Utan adalah budidaya udang. Sementara itu, pengelolaan sumber daya alam di kawasan hutan pesisirnya selama ini cenderung kurang ditingkatkan, hal ini disebabkan oleh berbagai hal, salah satunya kurangnya kesadaran masyarakat akan pentingnya penghijauan pantai dan pemeliharaan hutan pantai yang ada. Melalui program pembibitan mangrove sebagai upaya pemulihan lingkungan di kawasan pesisir ini diharapkan dapat menumbuhkan kesadaran dan peran aktif masyarakat akan pentingnya lingkungan yang sehat. Hasil dari kegiatan pengabdian ini menunjukkan keberhasilan  dengan terbentuknya kelompok petani mangrove, pembinaan kelompok petani mangrove dengan melakukan edukasi berkala dan pembangunan rumah pembibitan mangrove. Rumah pembibitan mangrove ini dikelola langsung oleh sekelompok petani mangrove dan berhasil menghasilkan 2.500-4.000 bibit mangrove serta berhasil dipasarkan. Kesimpulannya, kegiatan pengabdian ini berhasil dilaksanakan dan terbukti mampu meningkatkan kesejahteraan petani di sekitar pesisir. Selain itu, dengan adanya pembibitan mangrove ini, masyarakat dapat ikut berkontribusi dalam proses penanamannya sehingga banyak karbon yang terserap di atmosfer dan kualitas udara di lingkungan Sumbawa menjadi berkualitas. Artinya perekonomian, sosial dan lingkungan menjadi berkelanjutan.

Abstract

Sektor pertanian merupakan salah satu yang paling rentan terhadap dampak perubahan iklim. Oleh karena itu, perubahan iklim memerlukan strategi adaptasi dan mitigasi, mengingat penghidupan petani sangat bergantung pada lingkungan alam dan faktor iklim. Penelitian ini bertujuan untuk mengetahui tingkat pengetahuan dan persepsi rumah tangga tani terhadap dampak perubahan iklim pada sektor pertanian. Penelitian dilakukan di Desa Batu Dulang, Kecamatan Batulanteh, Kabupaten Sumbawa, yang terkenal dengan praktik pertanian agroforestri. Pendekatan yang digunakan adalah kuantitatif dan kualitatif. Data kuantitatif dikumpulkan melalui survei rumah tangga tani dan dianalisis secara deskriptif menggunakan tabel. Survei melibatkan 100 responden dengan pertanyaan terkait pengetahuan dan persepsi mereka tentang perubahan iklim. Data kualitatif dikumpulkan melalui wawancara mendalam dengan rumah tangga tani untuk memperoleh pemahaman mendalam tentang pengalaman dan pemahaman masyarakat terkait perubahan iklim dan dampaknya. Hasil penelitian menunjukkan bahwa meskipun sebagian besar petani di Desa Batu Dulang telah menerapkan sistem pertanian agroforestri, mereka belum memiliki pengetahuan yang cukup tentang perubahan iklim dan dampaknya terhadap aktivitas pertanian. Namun, mereka menyadari bahwa pemanasan global sedang terjadi, yang ditandai dengan peningkatan suhu yang dirasakan. Informasi yang tersebar di antara petani cenderung merujuk pada praktik dan teknologi pertanian, sementara informasi terkait peringatan bencana dan faktor iklim masih terbatas. Sebagian besar informasi yang diterima petani berasal dari rekan sejawat dan organisasi tani seperti gapoktan. Diperlukan peningkatan literasi iklim dan penyuluhan intensif untuk meningkatkan pemahaman petani di Desa Batu Dulang mengenai dampak perubahan iklim, sehingga mereka dapat melakukan mitigasi yang tepat.

Abstract

Climate variability is one of the factors that directly and greatly affect cropping system and plant yield. It is therefore very important to obtain a good understanding about climate variability or changes in the climate and the effect of these changes to clearly understand the vulnerability of food crops as well as its agronomic impacts for us to create and implement adaptive strategies to mitigate its negative effects. This study assessed the effect of climate in rice crop yield in both irrigated and rainfed ecotype farming system in Nueva Ecija Province in the Philippines using semi-annual yield data and the different climate variables such as seasonal rainfall, mean temperature, minimum temperature, and relative humidity by using empirical/statistical method through time series analysis, and correlation analysis. Results indicated that rice yield for irrigated and rainfed ecosystem type of farming in Nueva Ecija show an overall increasing trend from year 1991-2018, although there are observed decline and fluctuations in some years. The different climate variables (i.e., rainfall, temperature, and humidity) show fluctuating trends and irregularities spanning from the year 1991-2018. But it showed overall decreasing trends for relative humidity and increasing trends for rainfall, minimum temperature, and mean temperature. There are significant correlations between rice yield the all the climate variables in both irrigated and rainfed farming ecosystem types.

Abstract

Nowadays, processed natural rubber products such as crumb rubber have become the demands of global consumers who are oriented towards export markets. Therefore, the economic impact is felt more, but there are still other consequences. The consequences are not only economically beneficial but can also be detrimental to environmental conditions. The process of making natural rubber into crumb rubber causes a negative impact by means of air pollution in the form of odour, which is rarely noticed. The purposes of this study were to analyse the ammonia concentration resulting from the processing of natural rubber into crumb rubber, and to identify the impact of ammonia contamination on the environment, particularly human health. This research was conducted using a review method with the help of colandr machine learning. The results of the review show that the concentration of ammonia produced from the processing of natural rubber into crumb rubber in Indonesia has passed the specified quality standard threshold. It is found to impact the environment such as damage to aquatic ecosystems and air quality, as well as effects on human health such as respiratory problems.

Abstract

Bage is a traditional fermented fish in Sumbawa made from lemuru fish (Sardinella lemuru). The aims of this study were to determine the chemical properties (moisture content and crude protein), microbial properties, and the panellist’s preferences for bage fish products after the addition of chitosan during the process. Optimization analysis using Response Surface Methodology showed that the temperature acquired was 60.93˚C. The chitosan concentration amounted to 3.51%, resulting in a water content of 23.47% and protein content of 49.91%. The number of microbial colonies in all treatments did not exceed the maximum limit of salted fish category product, based on SNI 8273 – 2016, but the fungal growth was found in samples with a temperature of 53 and 55˚C on the 20th day. The highest level of panellist preference for taste and aroma of bage fish was at a treatment temperature of 60 ° C with the addition of chitosan 4.62%, whereas the best texture was obtained by treatment at a temperature of 53˚C with the addition of 4.62% chitosan

Abstract

The degradation of water quality in the environment can be attributed to the discharge of wastewater from shrimp ponds. Conversely, solid waste in the form of shrimp shells presents an entrepreneurial opportunity through the extraction of chitosan, a substance with the potential to enhance water quality while contributing to environmental sustainability. Sampling for this study was conducted at the Vannamei Nusantara Gemilang pond, located in Tambakrejo Village, Malang Regency, East Java. The research employed an experimental methodology with a quantitative approach, supplemented by a literature review. Various doses of chitosan solutions were tested on shrimp pond wastewater. The optimal results were obtained at a dosage of 80 mg/L, significantly outperforming the untreated water. The test outcomes for the 80 mg/L dosage included: BOD (Biochemical Oxygen Demand) at 4.62 mg/L, Nitrite concentration at 0.045 mg/L, turbidity at 3.55 NTU (Nephelometric Turbidity Units), TSS (Total Suspended Solids) at 14.6 mg/L, TDS (Total Dissolved Solids) at 2974 mg/L, pH level at 6.31, and temperature at 31.40°C. Notably, the Total Dissolved Solids (TDS) levels did not meet quality standards, highlighting the need for further process optimization. These findings emphasize the potential of chitosan extraction as a sustainable solution, while also underscoring the importance of continued research into the economic feasibility of this waste-to-wealth approach. Further studies are necessary to refine the wastewater treatment process, quantify the economic benefits, and ensure the long-term viability of this entrepreneurial venture in environmental sustainability.
