Abstract

Lampung Province with South Sumatra, which has occupied Indonesia as the third largest exporter after Brazila in the past three decades. This export appeal has triggered the encroachment of protected forests for coffee cultivation (Bakri et al, 2018), which is now an eco-labeling issue of the risk of degradation on environmental quality. Since the coffee is already a protected HHBK product especially following HKm scheme, it has been conducted this research from August to September 2017 in Kecamatan Air Naningan, Tanggamus District, Lampung. Observation of tree shade, pole, shrubs and nurseries has made 30 plots of samples of vegetation observations over coffee agroforestry. Productivity data of coffee, kinds and types of inputs and prices in cultivation were obtained through interviews of HKm participants in accordance with each plot plus 2 other participants adjacent to the land. The OLS method is used to formulate the matetamtical relationship between coffee productivity and shading type for tree phase [Y1] and pole phase [Y2] with 5% accuracy level. Selection is done (i) choosing shade type which has positive parameter value to [Y1] only to be used to establish combination of silvicultural improvement design; (ii) perform input-output analysis to assign Net B / C, NPV and IRR for each type and phase shade as a local ecological silviculture act. Conclusion: (1) Types [and phases] that have real positive effects: petai (Parkia speciosa), and medang (Phoebe hunanensis), sonokeling (Dalbergia latifolia) [poles], (2) silviculture improvement plan with coffee composition + petai + medang and coffee + petai + sonokeling have NPV Rp.230.981.284 and Rp. 232.301.462, Net B / C obtained 61,3 and 62,1 and IRR obtained by 33,9% and 34,0%.Lampung Province with South Sumatra, which has occupied Indonesia as the third largest exporter after Brazila in the past three decades.

Abstract

Daya kompetisiekspor biji kopi esensinya sangat ditentukan oleh citarasa minumannya terutama unsur fragrance yang harus dibentuk dalam budidaya ekologis alami, bukan melalui proses pabrikasi untuk merespon isu lingkungan maupun ekolobeling. Penelitian ini bertujuan merumuskanmodel matematik antara kualitas fragrancekopi robusta sebagai fungsi dari faktor ekologis tanaman dan merancang pengembangan kedua kualitas itu. Penelitian dilaksanakan di KPHL Batutegi, fokus dalam HKm Sidodadi di Kecamatan Air Naningan, Tanggamus Lampung mulaiJuni sampai Juli 2017.Pengamatan vegetasi fase pohon, pancang, tiang dan semai dilakukan dengan pembuatan 15 plot sample ukuran 20m x 20m, dengan beda elevasi sekitar25m dari 400sampai 1.200m dpl. Sampling buahkopi 2-3 kg per plot secara komposit. Analisis citarasa dilakukan di Puslit Kopi dan Kakao Jember. Metode OLS (ordinary least square) pada taraf nyata 5-10% diterapkan dengan variabel respon fragrance, dengan variabel prediktorjenis-jenisnaungan.Hasil penelitian bahwayang berpengaruh nyata: terhadap fragrance fase pohon (durian), fase pancang (jambu), dan fase semai (bandotan, cempaka, cengkeh, kakao, kentangan, kerinyuh, dan takelan).

Abstract

One of the tourist destinations in Wan Abdul Rachman Forest Park in Lampung, which has a variety of butterflies, namely the Gita Persada Butterfly Park. Research development needs to be done so that this park gives visitors satisfaction and the sustainability of butterflies. This study aims to study how visitors perceive tourism activities. The method used through direct observation and closed interviews containing questionnaires with aspects of assessment of facilities and shuttles, accommodation, infrastructure and tourist attractions. The data obtained were analyzed using One Score One Indicator and analyzed using a Likert Scale. The results of the study show that the facilitation and service aspects, as well as infrastructure, are classified as normal, while the tourist objects are classified as good. Visitors' perceptions stated that repairs should be made to the parking area, construction of counters, gift shops, information signs, tourgues, camping ground, homestays, tree houses and photo booths.

Abstract

Pendugaan karbon di atas permukaan tanah dari vegetasi mangrove di Kecamatan Labuhan Maringgai, Kabupaten Lampung Timur penting dilakukan karena memiliki kemampuan mengikat karbon jauh lebih tinggi dibandingkan dengan hutan terestrial dan hutan hujan tropis. Penelitian ini bertujuan untuk menduga stok karbon di atas permukaan tanah dari ekosistem mangrove menggunakan inventarisasi hutan terestrial dan citra satelit resolusi tinggi. Jenis mangrove dipetakan menggunakan citra satelit resolusi tinggi SPOT 6/7 menggunakan metode Object-Oriented Classification (OOC), dan di dalam lokasi mangrove telah dibuat 33 sampel plot masing-masing seluas 400 . Dari hasil analisis citra satelit didapatkan akurasi peta tipe mangrove yang sangat baik (97,75% dari akurasi keseluruhan), sehingga dapat dipetakan sebanyak 486 hektar kawasan mangrove di lokasi penelitian. Kawasan mangrove terluas terletak di Desa Margasari dan Sriminosari. Dari inventarisasi hutan didapatkan rata-rata stok karbon di atas permukaan tanah hutan mangrove adalah 65 tC / ha, dengan total estimasi stok karbon di atas permukaan tanah adalah 25.796,39 tC.
