Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh ukuran kuming terhadap pertumbuhan dan hasil tanaman ubi jalar. Perlakuan dalam penelitian ini adalah kuming kecil dengan diameter 25 cm (P1), Kuming sedang dengan diameter 50 cm (P2), dan Kuming besar dengan diameter 100 cm (P3). Hasil penelitian menunjukan bahwa Ukuran kuming (kecil, sedang, dan besar) mempengaruhi pertumbuhan vegetatif (panjang sulur, jumlah sulur, dan berat brangkasan daun) dan generatif (berat brangkasan akar, berat akar pensil, berat akar serabut, jumlah akar pensil, dan panjang akar pensil) pada tanaman ubi jalar. Pada variable pengamatan panjang sulur kuming yang memberikan hasil tertinggi adalah kuming sedang (P2), sedangkan hasil tertinggi untuk jumlah sulur dan berat brangkasan daun terdapat pada perlakuan kuming kecil (P1). Pada penelitian ini tidak menghasilkan umbi (umbi kecil, umbi sedang, umbi besar), tetapi yang dihasilkan adalah umbi-umbi pensil dan terdapat banyak akar serabut. Kekurangan unsur hara dalam tanah terutama unsur kalium dan juga kemampuan adaptasi varietas yang rendah diduga merupakan faktor yang mempengaruhi hasil pertumbuhan vegetatif maupun pertumbuhan generatif tanaman ubi jalar. Kata kunci : Kuming; Pertumbuhan dan Hasil Tanam; Ubi Jalar

Abstract

Abstract The potential of sago in Merauke Regency is very large when compared to other regions in Papua. Sago is a plant with high socio-cultural and economic values ​​in the Papuan community in general and for the Marind ethnic group in particular. Tambat processing centers in Merauke Regency only exist in Kampung Tambat, where almost all of these sago starch products are sold to meet market needs. However, due to limited production, it has not fulfilled market needs, this can be seen from the sago starch produced is always sold out. The purpose of this study was to obtain a picture of the sago processing business. Data collection techniques were carried out by field observations and interviews. The results of the study showed that there were two farmer groups namely the Marind and Mandobo groups who carried out sago plant development and sago starch processing activities. Sago processing technology is still traditionally carried out in stages: felling, stripping the skin, grating and extraction processes. The average income of a sago processor in a one-time processing that takes 3-4 days for the Marind group is Rp. 730,000 and the Mandobo group Rp. 680,000. Sago starch marketing is still limited to meet the needs of the local market. Keywords : processing sago starch; Tambat village

Abstract

Heterosis indication for high yield in F1 offspring has a very important meaning in the formation of hybrid varieties of corn (Zea mays L.). Through artificial hybrid between the parents, it can be found out the potential of a hybrid combination result, the value of heterosis, and the combined power. Hybrids between a few lines or corn varieties are to obtain a new hybrid with superior character compared to its parents which are expected to have high heterosis value. This research aims to find out heterosis value of some quantitative characters of F1 and F1R; a hybrid of two species of corn. It is conducted at Doyo Lama Village, Waibu Sub-district, Jayapura District, from October 2018 to August 2019. The research method is an experimental method in which the research consists of two stages; (1) experiment 1: hybrid between parents using single cross of hybrid method towards 2 genotypes of corn parents (J-Doyo 1 and J-Arso 1)to produce 2 genotypes of hybrid: F1 and F1R. (2) experiment 2: genetic evaluation to presume heterosis value from the character being studied. The findings reveal that F1 hybrid of JH-Arsol male x Doyol female has superiority for all characters compared to both parents, such as cobs length is 18,07 cm, cobs diameter is 5,10 cm, the number of rows of seeds per cob is 13,67 rows of seeds. Meanwhile, F1R JH hybrid of JH-Arsol female x Doyol male has superiority for all characters compared to both parents, such as cobs length is 22,93 cm, cobs diameter is 4,73 cm, the number of rows of seeds per cob is 13,00 rows of seeds. The offspring of F1 and F1R hybrid has more superiority than the parents, which is shown by positive heterosis value for all characters being studied.

Abstract

This study aims to look at the application of acetoin-producing rizobacteria as biofertilizers for boosting the growth of rice plants in dissolving phosphates and fixing nitrogen. The experimental design used was a randomized block design (RBD), consisting of 6 (six) treatments, 4 (four) treatments with rizobacteria isolates (Rg21 isolates, Pd13 isolates, Pd7 isolates, and Bb7 isolates), one treatment with synthetic acetoin, and one control. Each treatment was repeated 4 (four) times so that there were 24 experimental units consisting of 10 pots of rice plants. The size of the pot used is a surface diameter of 30 cm, filled with growth media in the form of a layer of paddy soil (taken to a depth of 20 cm from the soil surface) and compost with a ratio of 3: 1. The results showed that the treatment of rhizobacteria producing acetoin was able to spur the growth of rice plants by dissolving phosphates that were still bound by colloidal soil so that it was not available for plants to become available P. Likewise, rhizobacterial treatment is able to fix Nitrogen by changing enzymatically organic N compounds into ammonium

Abstract

This study was to examine the effect of changes in digestive tract that is seen from the length of the small intestine size of broiler chickens given kefir. The study used 200 MB of broiler DOC as many as 200 animals which were kept randomly in a cage plot. The study was conducted for 5 weeks with 4 treatments and repeated 5 times so that the number of experimental units was 20 units. The treatments to be tested were: T0 = basal ration (control), T1 = basal ration + 1.5% probiotic, T2 = basal ration + 3% probiotic, T3 = basal ration + 4.5%. Kefir used was derived from goat milk which was given 10% kefir grain fermented for 48 hours. The data obtained were analyzed for variance based on a completely randomized design and continued using duncan test. The results showed that the final body weight was significantly different (P <0.05), while the feed efficiency, relative length of duodenum, jejunum, ileum, overall small intestine and cecum had no significant effect (P> 0.05). The conclusion that the administration of probiotics in the form of kefir has no significant effect on the relative length of the small intestine and cecum, but has a significant effect on final body weight. The use of kefir needs to be considered in terms of cost because it uses milk as a fermentation media.

Abstract

The sea highway program aims to connect the western and eastern parts of Indonesia and reduce price disparities. The implementation began in December 2020 using ship namely Logistik Nusantara 2 with route from Merauke-Pomako-Kokas-Sorong-Korido-Merauke. The capacity of T19 is 1500 tons with revolving for one month. The purpose of this study is to evaluate the implementation of sea highway program route T19 in supporting the Merauke food estate program. Methodology used qualitative through literature study and verification primary data with interviewed the stakeholders. The results showed that the main cargo from Merauke is rice as market demand from Jayapura, Timika and Sorong. The shipload return to Merauke is chipped rock, sand, and rock ash. The differences of distribution cost is Rp. 150/kg when compared to private shipping. However, the loading capacity is relatively low, on average, 33.46% are filled, while the return load is 10.47%. The conclusion, sea highway program for the T19 route is an important vehicle in the distribution and marketing process of rice, especially for distributing rice from surplus to deficit areas. The contribution is very important in developing the food estate program, but it is necessary to optimalization of these transportation to fullfill the load target.

Abstract

Tanaman hias krisan merupakan salah satu tanaman hortikultura yang saat ini banyak diminati oleh kalangan pecinta tanaman hias khususnya di daerah perkotaan. Saat ini budidaya tanaman krisan hanya terbatas di dataran tinggi, sehingga permintaan pasar akan bunga krisan belum bisa dipenuhi secara berkelanjutan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian PGPR air limbah cucian beras dan ekstrak akar rumput gajah serta pengaruh macam media tanam untuk pertumbuhan produksi bibit stek tanaman krisan sehingga dapat diperoleh bibit yang berpotensi tumbuh dan berkembang di dataran rendah. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial dengan perlakuan konsentrasi PGPR (air cucian beras dan ekstrak akar rumput gajah) dan macam media tanam. Penelitian ini menggunakan analisis ragam dengan model Rancangan Acak Lengkap (RAL) Faktorial, jika terdapat beda nyata maka dilanjutkan menggunakan uji BNJ 5%. Hasil penelitian ini menunjukkan bahwa faktor perlakuan kombinasi perlakuan PGPR dan media tanam terdapat interaksi nyata terhadap parameter jumlah daun tanaman krisan, nampak pada kombinasi konsentrasi PGPR 400 ml/l + sekam bakar+tanah (2:1) pada pengamatan 35 HST. Kemudian faktor tunggal perlakuan media tanam memberikan pengaruh nyata terhadap parameter pertumbuhan tanaman krisan. Selain itu faktor tunggal pemberian PGPR memberikan pengaruh nyata terhadap parameter pertumbuhan tanaman krisan.
