Abstract

Protected forests serve as the fundamental protection for the support system of life, regulating water resources, preventing floods, controlling erosion, mitigating saltwater intrusion, and preserving soil fertility. However, in reality, many protected forests are converted into agricultural land. To address this issue, the government grants land use permits through the Community Forest (HKm) system. The HKm system typically involves planting a combination of agricultural and forestry crops (agroforestry). The variety of crops grown in one area yields abundant harvests, but it also generates a significant amount of waste. Consequently, waste becomes a problem, although plant waste can be utilized to make compost. The objective of this community service activity is to provide education and training on making compost blocks. The method employed in this activity is education and training provided to farmers. The results of this community service activity enhance the knowledge of the Pujo Makmur Farmer Group regarding the benefits of compost blocks, the process of making them, and their usage.

Abstract

Sugar palm (Arenga pinnata) is a palm plant that has many benefits but has a hard seed coat and is impermeable to water and oxygen. besides that the palm skin also contains ligin so that the seeds is dormant. Proper scarification technique needs to be done to overcome the dormancy in the palm seeds. Fermentation and deopercolation are scarification methods used to break the dormancy period of palm seeds. The purpose of this study was to determine the scarification method to break the dormancy period of sugar palm seeds by using the percent germination parameter. Fermentation was carried out with cow dung tested for 0.2, 4, 6 weeks. While deopercolation was carried out using sandpaper with a paper roughness level of 80, sanding was carried out on the backs of the palm seeds where the roots would appear. Each treatment was repeated three times in each replication using 15 sugar palm seeds. This research was conducted for 2 months in the greenhouse of the Faculty of Agriculture, University of Lampung. The results showed that the best treatment was the fermentation method for 6 weeks combined with deopercolation with a germination percentage value of 82.22%. The use of abrasive paper for the deopercolation method needs further research, the results of this study can be used in the practice of sugar palm cultivation

Abstract

Pertumbuhan kota yang pesat di Kota Madya Bandar Lampung mendorong kebutuhan akan pemantauan dan pengelolaan lahan terbuka hijau (RTH) secara efektif. RTH memiliki peran vital dalam menjaga keseimbangan ekosistem dan kualitas lingkungan perkotaan. Penelitian ini bertujuan untuk mengidentifikasi tutupan lahan terbuka hijau menggunakan pendekatan machine learning dengan algoritma Gaussian Mixture Model (GMM). Data citra satelit resolusi menengah digunakan sebagai basis pengolahan spasial, yang kemudian diproses melalui tahapan pra-pemrosesan seperti koreksi geometrik dan peningkatan citra. GMM diterapkan untuk melakukan klasifikasi tak terawasi terhadap jenis tutupan lahan berdasarkan spektrum nilai piksel. Hasil analisis menunjukkan bahwa algoritma GMM mampu memetakan area RTH dengan akurasi yang cukup tinggi, dan memberikan informasi spasial yang mendukung perencanaan kota berkelanjutan. Studi ini menegaskan potensi penggunaan metode machine learning dalam pemetaan tutupan lahan secara efisien dan adaptif di wilayah urban.

Abstract

Ekosistem mangrove memiliki fungsi ekologis yang penting, antara lain sebagai penahan abrasi, habitat biota perairan, penyerap karbon, serta penunjang ekonomi masyarakat pesisir. Namun kawasan mangrove di Kecamatan Labuhan Maringgai mengalami degradasi serius akibat konversi lahan, abrasi pantai, dan tekanan aktivitas masyarakat pesisir yang tidak terkendali. Pemantauan kondisi mangrove dapat dilakukan dengan memanfaatkan teknologi penginderaan jauh. Penelitian ini bertujuan untuk membandingkan kinerja indeks vegetasi NDVI, GNDVI, dan SAVI dalam mendeteksi kerapatan tutupan lahan mangrove secara cepat dan akurat, serta melakukan reklasifikasi dan estimasi perubahan luas tutupan mangrove periode 2013–2025. Penelitian ini dilakukan pada bulan Februari 2025 di Kecamatan Labuhan Maringgai, Kabupaten Lampung Timur, Lampung. Metode yang digunakan meliputi analisis citra satelit Landsat 8 dengan pengolahan NDVI, GNDVI, dan SAVI, dilengkapi validasi lapangan melalui Ground Truth Point (GTP). Hasil penelitian menunjukkan bahwa NDVI dengan model regresi cubic memiliki akurasi tertinggi dalam mendeteksi kerapatan mangrove dengan nilai R² sebesar 0,978 dan F sebesar 237,969. Sementara itu, GNDVI dan SAVI lebih efisien menggunakan model linear karena sederhana namun stabil. Reklasifikasi peta indeks vegetasi menunjukkan bahwa tutupan mangrove di Kabupaten Lampung Timur mengalami dinamika yang fluktuatif, dengan peningkatan pada tahun 2015–2017 namun penurunan drastis sejak 2019 hingga mencapai titik terendah pada 2025 akibat tekanan antropogenik dan abrasi pantai.

Abstract

Nature-based tourism continues to grow as a popular tourism activity among the public. Effective destination management must prioritize destination quality to provide an optimal visitor experience. This study aimed to analyze visitors’ perceptions of the quality of the Jungle Tracking nature tourism destination in Sumber Agung Village. Perceptions were assessed based on five aspects: tourist attractions, infrastructure, facilities and services, accommodation, and organization and human resources. This study used a survey method with questionnaires distributed to 68 visitors participating in Jungle Tracking activities during the research period. Most respondents were dominated by young visitors aged 17–25 years. Data were analyzed descriptively using a Likert scale. The results showed that visitors’ perceptions of the quality of the Jungle Tracking destination were generally in the “fairly good” to “good” categories. The tourist attraction aspect received the highest assessment due to the natural scenery and environmental conditions of the area. Meanwhile, infrastructure and tourism facilities were considered adequate, although several components still need improvement, particularly directional signs, tourist information, and management coordination. Improving facilities and destination management is necessary to support sustainable nature tourism development in Sumber Agung Village.

Abstract

Coffee production potential is matched by waste from grinding coffee cherries. However, the coffee cherry peel (husk) is rich in essential nutrients for plant growth, including potassium, phosphorus, and nitrogen. Therefore, the purpose of this research was conducted to determine the physical quality of coffee husk compost given the addition of EM4 bioactivator. This study consisted of 2 treatments and 4 replications, namely control (coffee husk + sawdust + goat manure) and EM4 (coffee husk + sawdust + goat manure + EM4). Observations were made every 3 days until the compost was ripe with the parameters of temperature, humidity, color, smell, and texture. The results showed that the entire coffee husk compost had matured within 36 days and exhibited physical characteristics according to SNI 19-7030-2004. According to the matured compost speed, treatment with mixing compost materials using EM4 shows a faster time than without EM4. In addition, the addition of EM4 gives better results in terms of texture, color, and smell compared to compost without EM4
