Abstract

Shallot is one of important horticultural crops in Indonesia; shallot consumption per capita is estimated to be 4.6 kg per year. The objective of this study was to evaluate the effect of combining biofertilizer and organic fertilizer on the production of shallot in Sukabanjar village, Pesawaran, Lampung, Indonesia. The study was set up using a randomized completely block design with two factors, biofertilizers and various organic fertilizers, i.e. cow manure, chicken manure, rice straw compost, oyster mushroom baglog. Our study demonstrated that combining biofertilizer and organic fertilizer significantly increased the number, diameter, and fresh and dry weight of tubers of “Bima Brebes” shallot. Shallots treated with biofertilizer combined with oyster mushroom baglog produced the highest tuber yield of 1788 g compared to 282 g in the control.

Abstract

Fruit quality is an important aspect that requires attention and more study when it comes to commercializing tropical fruits, including guava ‘Kristal’. This study aimed to evaluate the effect of bagging treatment and altitude of growing orchard on fruit quality of guava (Psidium guajava var. ‘Kristal’). This study was conducted at two local orchards managed by small-scale farmers, at Gunung Batu (1000 meters above sea level, m asl) and Brajaselebah (25 m asl), Lampung Province, Indonesia. A nested design was applied to test 5 types of bagging treatments and 2 levels of land altitude. Fruit quality was assessed by measuring both physical and chemical characteristics. Fruit size indicated by fruit weight and diameter was significantly larger in lowland compared to highland. The total soluble solids (TSS) were significantly higher in the lowland compared to the highland, while titratable acid (TA) showed an opposite result. Vitamin C of the fruits varied from140 to 146 mg per 100 g. Different types of fruit bagging and land altitudes did not affect the physical and chemical characteristics of “Kristal” guava fruits. Fruit scar intensity was higher in lowland, especially in fruit without bagging. Fruit bagging is highly recommended for farmers due to the success of this treatment to reduce fruit scar intensity, thus resulting in good fruit quality, irrespective of the growing locations.

Abstract

ABSTRACT Arrangement of Guava Flowering (Psidium guajava L.) ‘Krystal’ through the Application of Different Strangulation Times. The seasonal production of guava (Psidium guajava) requires flowering manipulation technique such strangulation in order to be available throughout the years. This study aimed to explain the relationship between strangulation time, the period of flowering and harvesting of guava cv 'Krystal'. The experiment was conducted from February to December 2017, in Cikabayan experimental garden of IPB University, Bogor, Indonesia. The experiment used a completely randomized design with single factor, i.e strangulation times that consisted of control (no strangulation), strangulation in March, in April and in May. The results showed that strangulation treatment was able to accelerate the emergence of flowers and increase the number of generative shoots, the number of flowers per tree and the number of fruits harvested. The increase of flowering response on strangulated trees was supported by a higher leaf C/N compared to control, which is related to the low leaf N content in strangulation treatments. The strangulation treatment could accelerate the time of flower emergence six days earlier than control.  Keywords: guava, C/N, flowering induction, ringing, seasonal production ABSTRAK Produksi buah jambu biji (Psidium guajava) yang bersifat musiman memerlukan teknik pengaturan pembungaan agar dapat tersedia sepanjang tahun. Penelitian ini bertujuan untuk menjelaskan keterkaitan antara waktu strangulasi dengan pola pembungaan dan panen buah jambu biji ‘Kristal’. Percobaan dilaksanakan mulai Februari sampai Desember 2017, di Kebun Percobaan Cikabayan IPB Bogor. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan faktor tunggal yaitu waktu strangulasi yang terdiri dari 4 (empat) taraf, yakni tanpa strangulasi, strangulasi bulan Maret, strangulasi bulan April dan strangulasi bulan Mei. Hasil penelitian menunjukkan bahwa perlakuan strangulasi mampu mempercepat munculnya bunga dan meningkatkan jumlah tunas generatif, jumlah bunga per pohon, jumlah bakal buah per pohon dan jumlah buah yang dipanen. Peningkatan respon pembungaan akibat strangulasi didukung oleh C/N daun yang lebih tinggi dibandingkan tanpa stangulasi, yang berhubungan dengan rendahnya kandungan nitrogen daun pada perlakuan strangulasi. Perlakuan strangulasi mampu mempercepat waktu muncul bunga 6 hari lebih cepat dibandingkan tanpa strangulasi.Kata kunci: jambu biji, C/N, induksi pembungaan, pencekikan batang, produksi musiman

Abstract

Pakchoy (Brassica sinensis L.) merupakan tanaman sayuran yang kualitasnya sangat ditentukan oleh tekstur yang renyah. Salah satu cara untuk mendapatkan kualitas tersebut dapat ditempuh dengan penambahan bahan organik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian bahan organik berupa limbah baglog jamur dan pemberian takaran NPK serta interaksinya terhadap pertumbuhan dan produksi tanaman pakchoy. Penelitian ini telah dilaksanakan pada bulan April sampai dengan bulan Juni 2014 di kebun percobaan Universitas Lampung. Penelitian ini disusun dengan menggunakan Rancangan Teracak Sempurna (RTS) yang disusun secara faktorial dengan tiga ulangan. Faktor pertama adalah dosis limbah baglog jamur (P) dan faktor kedua adalah takaran NPK mutiara 16-16-16 (L). Pertama: p 0 = 0 kg m -2 , p 1 = 10 kg m -2 , dan kedua: l 0 = 0 g m -2 NPK, l 1 = 50 g m -2 NPK, l 2 = 100 g m -2 NPK, l 3 = 150 g m -2 NPK, l 4 = 200 g m -2 NPK. Setiap kombinasi perlakuan diulang tiga kali dan setiap satuan percobaan terdiri dari 25 tanaman sehingga didapatkan 30 satuan percobaan dan total tanaman sebanyak 750 tanaman. Perlakuan yang menunjukkan pengaruh nyata dilanjutkan dengan pemisahan nilai tengah menggunakanuji Beda Nyata Terkecil (BNT) pada taraf α 5%. Hasil penelitian menunjukkan bahwa pemberian bahan organik berupa limbah baglog jamur berpengaruh nyata terhadap variabel bobot kering tanaman. Pemberian pupuk takaran NPK juga berpengaruh nyata terhadap semua variabel pengamatan dan dosis terbaik terdapat pada 200 g m -2 , sedangkan interaksi antara dua perlakuan tersebut tidak memberikan pengaruh yang nyata terhadap semua variabel pengamatan.

Abstract

Pelatihan pembuatan dan pengemasan masker kopi dilatarbelakangi oleh banyaknya produksi kopi di Desa Manggarai, salah satu desa peghasil kopi robusta di Kabupaten Lampung Barat. Namun, karena minimnya infomasi, pengalaman dan edukasi, kopi hanya dijual dalam bentuk mentah atau bubuk kopi saja, oleh sebab itu diperlukan adanya diversivikasi olahan kopi yang dapat meningkatkan nilai jual kopi, salah satunya adalah masker berbahan dasar kopi. Kegiatan ini dilaksanAkan pada 25 Januari 2020 di Desa Manggarai dengan diikuti oleh 24 peserta dari ibu ibu kelompok wanita tani dan BUMDES dengan di pandu dengan mahasiswa KKN Unila. Kegiatan yang dilakukan yaitu dimulai dengan penjelasan mengenai produk turunan dari kopi yang dapat dimanfaatkan sebagai masker yang berfungsi sebagai produk perawatan wajah, kemudian dilanjutkan praktik pembuatan masker. Masker berbahan dasar campuran antara kopi, kunyit dan beras dimana ketiga bahan tersebut masing masing diblender kemudian dicampur menjadi satu, setelah itu dilakukan pengemasan dan ditempel stiker yang telah didesain sebelumnya. Dari kegiatan tersebut diharapkan peserta dapat mengadopsi dan menduplikasi sebagai produk unggulan desa yang dapat di jual melalui BUMDES. Testimoni peserta yang mencoba adalah jerawat menjadi cepat kempes dan adanya rasa lebih baik/segar pada wajah setelah memakai masker.

Abstract

Umumnya bahan tanam Singkong berasal dari stek batang yang diambil dari sisa panen penanaman sebelumnya. Jumlah akar yang tumbuh pada stek batang dan menjadi umbi adalah salah satu faktor yang menentukan tinggi rendahnya produksi singkong. Beberapa literatur menyatakan bahwa beberapa sistem pelukaan batang atau pengeratan akan mempegaruhi pertumbuhan dan jumlah akar yang tumbuh dari batang. Tujuan penelitian ini adalah untuk mengetahui pengaruh pengeratan pada pertumbuhan akar (panjang dan jumlah) dan produksi umbi Singkong. Peneltian ini berlangsung pada bulan Juli sampai November 2020 di Laboratorium Lapang Terpadu Fakultas Pertanian, Universitas Lampung. Hasil penelitian memperlihatkan bahwa perlakuan pengeratan akan meningkatkan panjang akar, dan jumlah akar singkong hingga umur 8 minggu setelah tanam, tetapi kemudian menurun pada 16 miggu setelah tanam. Pertumbuhan akar singkong optimum yang terjadi pada umur 8 minggu ditandai dengan panjang akar maksimum sepanjang 17.97 cm dan jumlah akar sebanyak 41,42 buah. Dalam aspek produksi, pada minggu ke 16 setelah tanam terjadi penurunan jumlah umbi singkong dari 7,25 buah pada perlakuan kontrol menjadi 4,375 buah pada perlakuan keratan. Hal ini diduga karena penerapan teknik budidaya yang kurang tepat terutama pada kegiatan pemupukan dan pemangkasan.

Abstract

This research aims to analyze the impact of climate change on the productivity of rice farming businesses, know the knowledge, attitudes, and adaptability to climate change, and present a review and criticism analysis for product updates related to climate change. The study respondents numbered 100 rice farmers in Lampung Province. The processed data is analyzed by using descriptive statistics, using Crosstabs analysis to calculate the frequency and percentage of two or more variables at once while to see the influence of farmer behavior is using path analysis. The results of this study showed that the impact of climate change greatly affects rice farming businesses which leads to a decrease in the productivity of farmers' rice farming businesses. The lack of knowledge of farmers about climate change and the attitude of farmers in dealing with climate change are great concern, but in the follow-up to curiosity and problem solving tends to be less, this is due to farmers less enthusiastic in determining the attitude of climate change. The level of adaptation of farmers to climate change only occurs when determining planting time, so it needs to increase the power due to climate change. Recommendations from these results, among others, related to regulations that require renewal. This update obtained two perspectives, namely the legal perspective and the perspective of the development of the climate issue itself.
